Macronutrient Optimization for Sports and Performance -
It is well documented that exercise performance is greatly influenced by nutrition. The key factor in coping with the heavy demands of exercise faced by elite athletes seems to be carbohydrate intake.
Players who begin a match with low glycogen stores will typically cover less distance and complete less high-speed runs, particularly in the second half, which can have huge ramifications on individual and potentially team performance and may contribute to the outcome of the match.
This emphasises the importance of prioritising a balanced diet that will improve an athletes physical performance on gameday. Carbohydrates are essential for optimal match day performance as it is the primary fuel for muscle during high intensity activities.
It is the key macronutrient for proper preparation for match day. Below is an example of what a typical athletes game day nutrition should look like with Kick Off according to Richard Allison.
From the carbohydrate loading to having a balanced healthy diet in the weeks and days building up to gameday.
With proper hydration, your body will be able to perform at its best. Hydration for athletes is essential to maintain normal blood circulation because this aids the delivery of nutrients and oxygen to every working muscle in the body.
As water is involved in the majority of chemical reactions involved in athletic performance it is therefore important that athletes are hydrated before, during and after physical activity to achieve their maximal physical performance.
Hydration enhances your motor neurons. Your muscles move only when they receive commands from your brain. These commands move through neural pathways, which depend on adequate hydration to function at their best.
When exercising, you need your motor neurons at their top potential — otherwise your speed and strength can decrease. Your body needs fluids to transport energy nutrients. Hydration helps regulate your body temperature.
A similar conclusion was also drawn by Pasiakos et al. Results from many single investigations indicate that in both men and women protein supplementation exerts a small to modest impact on strength development.
Pooled results of multiple studies using meta-analytic and other systematic approaches consistently indicate that protein supplementation 15 to 25 g over 4 to 21 weeks exerts a positive impact on performance.
Andersen et al. When the blend of milk proteins was provided, significantly greater increases in fat-free mass, muscle cross-sectional area in both the Type I and Type II muscle fibers occurred when compared to changes seen with carbohydrate consumption.
Collectively, a meta-analysis by Cermak and colleagues [ 35 ] reported a mean increase in fat-free mass of 0. Other reviews by Tipton, Phillips and Pasiakos, respectively, [ 36 , 38 , 39 ] provide further support that protein supplementation 15—25 g over 4—14 weeks augments lean mass accretion when combined with completion of a resistance training program.
Beyond accretion of fat-free mass, increasing daily protein intake through a combination of food and supplementation to levels above the recommended daily allowance RDA RDA 0. The majority of this work has been conducted using overweight and obese individuals who were prescribed an energy-restricted diet that delivered a greater ratio of protein relative to carbohydrate.
Greater amounts of fat were lost when higher amounts of protein were ingested, but even greater amounts of fat loss occurred when the exercise program was added to the high-protein diet group, resulting in significant decreases in body fat.
Each person was randomly assigned to consume a diet that contained either 1× 0. Participants were measured for changes in body weight and body composition.
While the greatest body weight loss occurred in the 1× RDA group, this group also lost the highest percentage of fat-free mass and lowest percentage of fat mass.
Collectively, these results indicate that increasing dietary protein can promote favorable adaptations in body composition through the promotion of fat-free mass accretion when combined with a hyperenergetic diet and a heavy resistance training program and can also promote the loss of fat mass when higher intakes of daily protein × the RDA are combined with an exercise program and a hypoenergetic diet.
When combined with a hyperenergetic diet and a heavy resistance-training program, protein supplementation may promote increases in skeletal muscle cross-sectional area and lean body mass.
When combined with a resistance-training program and a hypoenergetic diet, an elevated daily intake of protein 2 — 3× the RDA can promote greater losses of fat mass and greater overall improvements in body composition.
In the absence of feeding, muscle protein balance remains negative in response to an acute bout of resistance exercise [ 48 ]. Tipton et al. Later, Burd et al. Subsequently, these conclusions were supported by Borsheim [ 52 ] and Volpi [ 53 ].
The study by Borsheim also documented a dose-response outcome characterized by a near doubling of net protein balance in response to a three to six gram dose of the EAAs [ 52 ]. Building on this work, Tipton et al. These findings formed the theoretical concept of protein timing for resistance exercise that has since been transferred to not only other short-duration, high-intensity activities [ 56 ] but also endurance-based sports [ 57 ] and subsequent performance outcomes [ 58 ].
The strategic consumption of nutrition, namely protein or various forms of amino acids, in the hours immediately before and during exercise i. While earlier investigations reported positive effects from consumption of amino acids [ 37 , 46 , 61 ], it is now clear that intact protein supplements such as egg, whey, casein, beef, soy and even whole milk can evoke an anabolic response that can be similar or greater in magnitude to free form amino acids, assuming ingestion of equal EAA amounts [ 62 , 63 , 64 ].
For instance, whey protein ingested close to resistance exercise, promotes a higher activation phosphorylation of mTOR a key signaling protein found in myocytes that is linked to the synthesis of muscle proteins and its downstream mRNA translational signaling proteins i.
Moreover, it was found that the increased mTOR signaling corresponded with significantly greater muscle hypertrophy after 10 weeks of training [ 65 ]. However, the hypertrophic differences between protein consumption and a non-caloric placebo appeared to plateau by week 21, despite a persistently greater activation of this molecular signaling pathway from supplementation.
Results from other research groups [ 56 , 57 , 58 , 66 ] show that timing of protein near ± 2 h aerobic and anaerobic exercise training appears to provide a greater activation of the molecular signalling pathways that regulate myofibrillar and mitochondrial protein synthesis as well as glycogen synthesis.
It is widely reported that protein consumption directly after resistance exercise is an effective way to acutely promote a positive muscle protein balance [ 31 , 55 , 67 ], which if repeated over time should translate into a net gain or hypertrophy of muscle [ 68 ].
Pennings and colleagues [ 69 ] reported an increase in both the delivery and incorporation of dietary proteins into the skeletal muscle of young and older adults when protein was ingested shortly after completion of exercise.
These findings and others add to the theoretical basis for consumption of post-protein sooner rather than later after exercise, since post workout MPS rates peak within three hours and remain elevated for an additional 24—72 h [ 50 , 70 ].
This extended time frame also provides a rationale for both immediate and sustained i. These temporal considerations would also capture the peak elevation in signalling proteins shown to be pivotal for increasing the initiation of translation of muscle proteins, which for the most part appears to peak between 30 and 60 min after exercise [ 71 ].
However, these differences may be related to the type of protein used between the studies. The studies showing positive effects of protein timing used milk proteins, whereas the latter study used a collagen based protein supplement.
While a great deal of work has focused on post-exercise protein ingestion, other studies have suggested that pre-exercise and even intra-exercise ingestion may also support favorable changes in MPS and muscle protein breakdown [ 14 , 54 , 75 , 76 , 77 , 78 ].
Initially, Tipton and colleagues [ 54 ] directly compared immediate pre-exercise and immediate post-exercise ingestion of a mixture of carbohydrate 35 g and EAAs 6 g combination on changes in MPS. They reported that pre-exercise ingestion promoted higher rates of MPS while also demonstrating that nutrient ingestion prior to exercise increased nutrient delivery to a much greater extent than other immediate or one hour post-exercise time points.
These results were later challenged by Fujita in who employed an identical study design with a different tracer incorporation approach and concluded there was no difference between pre- or post-exercise ingestion [ 75 ].
Subsequent work by Tipton [ 79 ] also found that similar elevated rates of MPS were achieved when ingesting 20 g of a whey protein isolate immediately before or immediately after resistance exercise. At this point, whether any particular time of protein ingestion confers any unique advantage over other time points throughout a h day to improve strength and hypertrophy has yet to be adequately investigated.
To date, although a substantial amount of literature discusses this concept [ 60 , 80 ], a limited number of training studies have assessed whether immediate pre- and post-exercise protein consumption provides unique advantages compared to other time points [ 72 , 73 , 81 ].
Each study differed in population, training program, environment and nutrition utilized, with each reporting a different result. What is becoming clear is that the subject population, nutrition habits, dosing protocols on both training and non-training days, energy and macronutrient intake, as well as the exercise bout or training program itself should be carefully considered alongside the results.
In particular, the daily amount of protein intake seems to operate as a key consideration because the benefits of protein timing in relation to the peri-workout period seem to be lessened for people who are already ingesting appropriate amounts of protein e.
A literature review by Aragon and Schoenfeld [ 83 ] determined that while compelling evidence exists showing muscle is sensitized to protein ingestion following training, the increased sensitivity to protein ingestion might be greatest in the first five to six hours following exercise.
Thus, the importance of timing may be largely dependent on when a pre-workout meal was consumed, the size and composition of that meal and the total daily protein in the diet. In this respect, a pre-exercise meal will provide amino acids during and after exercise and therefore it stands to reason there is less need for immediate post-exercise protein ingestion if a pre-exercise meal is consumed less than five hours before the anticipated completion of a workout.
A meta-analysis by Schoenfeld et al. The authors concluded that total protein intake was the strongest predictor of muscular hypertrophy and that protein timing likely influences hypertrophy to a lesser degree.
However, the conclusions from this meta-analysis may be questioned because the majority of the studies analyzed were not protein timing studies but rather protein supplementation studies. In that respect, the meta-analysis provides evidence that protein supplementation i.
While a strong rationale remains to support the concept that the hours immediately before or after resistance exercise represents an opportune time to deliver key nutrients that will drive the accretion of fat-free mass and possibly other favorable adaptations, the majority of available literature suggests that other factors may indeed be operating to a similar degree that ultimately impact the observed adaptations.
In this respect, a key variable that must be accounted for is the absolute need for energy and protein required to appropriately set the body up to accumulate fat-free mass.
Thus, the most practical recommendation is to have athletes consume a meal during the post-workout or pre-workout time period since it may either help or have a neutral effect. In younger subjects, the ingestion of 20—30 g of any high biological value protein before or after resistance exercise appears to be sufficient to maximally stimulate MPS [ 21 , 64 ].
More recently, Macnaughton and colleagues [ 85 ] reported that 40 g of whey protein ingestion significantly increased the MPS responses compared to a 20 g feeding after an acute bout of whole-body resistance exercise, and that the absolute protein dose may operate as a more important consideration than providing a protein dose that is normalized to lean mass.
Free form EAAs, soy, milk, whey, caseinate, and other protein hydrolysates are all capable of activating MPS [ 86 ]. However, maximal stimulation of MPS, which results in higher net muscle protein accretion, is the product of the total amount of EAA in circulation as well as the pattern and appearance rate of aminoacidemia that modulates the MPS response [ 86 ].
Recent work has clarified that whey protein provides a distinct advantage over other protein sources including soy considered another fast absorbing protein and casein a slower acting protein source on acute stimulation of MPS [ 86 , 87 ].
Importantly, an elegant study by West and investigators [ 87 ] sought to match the delivery of EAAs in feeding patterns that replicated how whey and casein are digested.
The authors reported that a 25 g dose of whey protein that promoted rapid aminoacidemia further enhanced MPS and anabolic signaling when compared to an identical total dose of whey protein when delivered as ten separate 2. The advantages of whey protein are important to consider, particularly as all three sources rank similarly in assessments of protein quality [ 88 ].
In addition to soy, other plant sources e. have garnered interest as potential protein sources to consider. Unfortunately, research that examines the ability of these protein sources to modulate exercise performance and training adaptations is limited at this time. The investigators concluded that gains in strength, muscle thickness and body composition were similar between the two protein groups, suggesting that rice protein may be a suitable alternative to whey protein at promoting resistance training adaptations.
Furthermore, differences in absorption kinetics, and the subsequent impact on muscle protein metabolism appear to extend beyond the degree of hydrolysis and amino acid profiles [ 69 , 86 , 90 , 91 , 92 , 92 ]. For instance, unlike soy more of the EAAs from whey proteins hydrolysates and isolates survive splanchnic uptake and travel to the periphery to activate a higher net gain in muscle [ 86 ].
These characteristics yield a high concentration of amino acids in the blood aminoacidemia [ 69 , 87 ] that facilitates greater activation of MPS and net muscle protein accretion, in direct comparison to other protein choices [ 50 , 69 , 91 ].
The addition of creatine to whey protein supplementation appears to further augment these adaptations [ 27 , 72 , 95 ]; however, an optimal timing strategy for this combination remains unclear. The timing of protein-rich meals consumed throughout a day has the potential to influence adaptations to exercise.
Using similar methods, other studies over recent decades [ 53 , 62 , 87 , 91 , 96 , 97 , 98 , 99 , ] have established the following:.
The anabolic response to feeding is pronounced but transient. During the post-prandial phase 1—4 h after a meal MPS is elevated, resulting in a positive muscle protein balance. In contrast, MPS rates are lower in a fasted state and muscle protein balance is negative.
Protein accretion only occurs in the fed state. The concentration of EAA in the blood plasma regulates protein synthesis rates within muscle at rest and post exercise.
More recent work has established that protein-carbohydrate supplementation after strenuous endurance exercise stimulates contractile MPS via similar signaling pathways as resistance exercise [ 56 , 57 ].
That is, the consumption of a protein-containing meal up to 24 h after a single bout of resistance exercise results in a higher net stimulation of MPS and protein accretion than the same meal consumed after 24 h of inactivity [ 50 ]. The effect of insulin on MPS is dependent on its ability to increase amino acid availability, which does not occur when insulin is systematically increased e.
Taken together, these results seem to indicate that post-workout carbohydrate supplementation offers very little contribution from a muscle development standpoint provided adequate protein is consumed.
Importantly, these results are not to be interpreted to mean that carbohydrate administration offers no potential effect for an athlete engaging in moderate to high volumes of training, but rather that benefits derived from carbohydrate administration appear to more favorably impact aspects of muscle glycogen recovery as opposed to stimulating muscle protein accretion.
Eating before sleep has long been controversial [ , , ]. However, a methodological consideration in the original studies such as the population used, time of feeding, and size of the pre-sleep meal confounds firm conclusions about benefits or drawbacks.
Results from several investigations indicate that 30—40 g of casein protein ingested min prior to sleep [ ] or via nasogastric tubing [ ] increased overnight MPS in both young and old men, respectively. Likewise, in an acute setting, 30 g of whey protein, 30 g of casein protein, and 33 g of carbohydrate consumed min prior to sleep resulted in an elevated morning resting metabolic rate in young fit men compared to a non-caloric placebo [ ].
Interestingly, Madzima et al. This infers that casein protein consumed pre-sleep maintains overnight lipolysis and fat oxidation. This finding was further supported by Kinsey et al.
Similar to Madzima et al. Interestingly, the pre-sleep protein and carbohydrate ingestion resulted in elevated insulin concentrations the next morning and decreased hunger in this overweight population.
Of note, it appears that exercise training completely ameliorates any rise in insulin when eating at night before sleep [ ], while the combination of pre-sleep protein and exercise has been shown to reduce blood pressure and arterial stiffness in young obese women with prehypertension and hypertension [ ].
In athletes, evening chocolate milk consumption has also been shown to influence carbohydrate metabolism in the morning, but not running performance [ ].
In addition, data supports that exercise performed in the evening augments the overnight MPS response in both younger and older men [ , , ]. To date, only a few studies involving nighttime protein ingestion have been carried out for longer than four weeks.
Snijders et al. The group receiving the protein-centric supplement each night before sleep had greater improvements in muscle mass and strength over the week study.
Of note, this study was non-nitrogen balanced and the protein group received approximately 1. More recently, in a study in which total protein intake was equal, Antonio et al. They examined the effects on body composition and performance [ ].
All subjects maintained their usual exercise program. The authors reported no differences in body composition or performance between the morning and evening casein supplementation groups. However, it is worth noting that, although not statistically significant, the morning group added 0.
Although this finding was not statistically significant, it supports data from Burk et al. It should be noted that the subjects in the Burk et al. study were resistance training. A retrospective epidemiological study by Buckner et al. Thus, it appears that protein consumption in the evening before sleep might be an underutilized time to take advantage of a protein feeding opportunity that can potentially improve body composition and performance.
In addition to direct assessments of timed administration of nutrients, other studies have explored questions that center upon the pattern of when certain protein-containing meals are consumed.
Paddon-Jones et al. In this study, participants were given an EAA supplement three times a day for 28 days. Results indicated that acute stimulation of MPS provided by the supplement on day 1 resulted in a net gain of ~7.
When extrapolated over the entire day study, the predicted change in muscle mass corresponded to the actual change in muscle mass ~ g measured by dual-energy x-ray absorptiometry DEXA [ 97 ]. While these findings are important, it is vital to highlight that this study incorporated a bed rest model with no acute exercise stimulus while other work by Mitchell et al.
Interestingly, supplementation with 15 g of EAAs and 30 g of carbohydrate produced a greater anabolic effect increase in net phenylalanine balance than the ingestion of a mixed macronutrient meal, despite the fact that both interventions contained a similar dose of EAAs [ 96 ].
Most importantly, the consumption of the supplement did not interfere with the normal anabolic response to the meal consumed three hours later [ 96 ]. Areta et al.
The researchers compared the anabolic responses of three different patterns of ingestion a total of 80 g of protein throughout a h recovery period after resistance exercise. Using a group of healthy young adult males, the protein feeding strategies consisted of small pulsed 8 × 10 g , intermediate 4 × 20 g , or bolus 2 × 40 g administration of whey protein over the h measurement window.
Results showed that the intermediate dosing 4 × 20 g was superior for stimulating MPS for the h experimental period. Specifically, the rates of myofibrillar protein synthesis were optimized throughout the day of recovery by the consumption of 20 g protein every three hours compared to large 2 × 40 g , less frequent servings or smaller but more frequent 8 × 10 g patterns of protein intake [ 67 ].
Previously, the effect of various protein feeding strategies on skeletal MPS during an entire day was unknown.
This study provided novel information demonstrating that the regulation of MPS can be modulated by the timing and distribution of protein over 12 h after a single bout of resistance exercise. However, it should be noted that an 80 g dose of protein over a h period is quite low. The logical next step for researchers is to extend these findings into longitudinal training studies to see if these patterns can significantly affect resistance-training adaptations.
Indeed, published studies by Arnal [ ] and Tinsley [ ] have all made some attempt to examine the impact of adjusting the pattern of protein consumption across the day in combination with various forms of exercise. Collective results from these studies are mixed.
Thus, future studies in young adults should be designed to compare a balanced vs. skewed distribution pattern of daily protein intake on the daytime stimulation of MPS under resting and post-exercise conditions and training-induced changes in muscle mass, while taking into consideration the established optimal dose of protein contained in a single serving for young adults.
Without more conclusive evidence spanning several weeks, it seems pragmatic to recommend the consumption of at least g of protein ~0. In the absence of feeding and in response to resistance exercise, muscle protein balance remains negative. Skeletal muscle is sensitized to the effects of protein and amino acids for up to 24 h after completion of a bout of resistance exercise.
A protein dose of 20—40 g of protein 10—12 g of EAAs, 1—3 g of leucine stimulates MPS, which can help to promote a positive nitrogen balance.
The EAAs are critically needed for achieving maximal rates of MPS making high-quality, protein sources that are rich in EAAs and leucine the preferred sources of protein.
Studies have suggested that pre-exercise feedings of amino acids in combination with carbohydrate can achieve maximal rates of MPS, but protein and amino acid feedings during this time are not clearly documented to increase exercise performance. Total protein and calorie intake appears to be the most important consideration when it comes to promoting positive adaptations to resistance training, and the impact of timing strategies immediately before or immediately after to heighten these adaptations in non-athletic populations appears to be minimal.
Proteins provide the building blocks of all tissues via their constituent amino acids. Athletes consume dietary protein to repair and rebuild skeletal muscle and connective tissues following intense training bouts or athletic events.
A report in by Phillips [ ] summarized the findings surrounding protein requirements in resistance-trained athletes. Using a regression approach, he concluded that a protein intake of 1.
A key consideration regarding these recommended values is that all generated data were obtained using the nitrogen balance technique, which is known to underestimate protein requirements. Interestingly, two of the included papers had prescribed protein intakes of 2. All data points from these two studies also had the highest levels of positive nitrogen balance.
For an athlete seeking to ensure an anabolic environment, higher daily protein intakes might be needed. Another challenge that underpins the ability to universally and successfully recommend daily protein amounts are factors related to the volume of the exercise program, age, body composition and training status of the athlete; as well as the total energy intake in the diet, particularly for athletes who desire to lose fat and are restricting calories to accomplish this goal [ ].
For these reasons, and due to an increase of published studies in areas related to optimal protein dosing, timing and composition, protein needs are being recommended within this position stand on a per meal basis.
For example, Moore [ 31 ] found that muscle and albumin protein synthesis was optimized at approximately 20 g of egg protein at rest. Witard et al. Furthermore, while results from these studies offer indications of what optimal absolute dosing amounts may be, Phillips [ ] concluded that a relative dose of 0.
Once a total daily target protein intake has been achieved, the frequency and pattern with which optimal doses are ingested may serve as a key determinant of overall changes in protein synthetic rates. Research indicates that rates of MPS rapidly rise to peak levels within 30 min of protein ingestion and are maintained for up to three hours before rapidly beginning to lower to basal rates of MPS even though amino acids are still elevated in the blood [ ].
Using an oral ingestion model of 48 g of whey protein in healthy young men, rates of myofibrillar protein synthesis increased three-fold within 45—90 min before slowly declining to basal rates of MPS all while plasma concentration of EAAs remained significantly elevated [ ].
While largely unexplored in a human model, these authors relied upon an animal model and were able to reinstate increases in MPS using the consumption of leucine and carbohydrate min after ingestion of the first meal.
As such, it is suggested that individuals attempting to restrict caloric intake should consume three to four whole meals consisting of 20—40 g of protein per meal. While this recommendation stems primarily from initial work that indicated protein doses of 20—40 g favorably promote increased rates of MPS [ 31 , , ], Kim and colleagues [ ] recently reported that a 70 g dose of protein promoted a more favorable net balance of protein when compared to a 40 g dose due to a stronger attenuation of rates of muscle protein breakdown.
For those attempting to increase their calories, we suggest consuming small snacks between meals consisting of both a complete protein and a carbohydrate source.
This contention is supported by research from Paddon-Jones et al. These researchers compared three cal mixed macronutrient meals to three cal meals combined with three cal amino acid-carbohydrate snacks between meals. Additionally, using a protein distribution pattern of 20—25 g doses every three hours in response to a single bout of lower body resistance exercise appears to promote the greatest increase in MPS rates and phosphorylation of key intramuscular proteins linked to muscle hypertrophy [ ].
This simple addition could provide benefits for individuals looking to increase muscle mass and improve body composition in general while also striving to maintain or improve health and performance.
The current RDA for protein is 0. While previous recommendations have suggested a daily intake of 1. Daily and per dose needs are combinations of many factors including volume of exercise, age, body composition, total energy intake and training status of the athlete.
Daily intakes of 1. Even higher amounts ~70 g appear to be necessary to promote attenuation of muscle protein breakdown. Pacing or spreading these feeding episodes approximately three hours apart has been consistently reported to promote sustained, increased levels of MPS and performance benefits.
There are 20 total amino acids, comprised of 9 EAAs and 11 non-essential amino acids NEAAs. EAAs cannot be produced in the body and therefore must be consumed in the diet. Several methods exist to determine protein quality such as Chemical Score, Protein Efficiency Ratio, Biological Value, Protein Digestibility-Corrected Amino Acid Score PDCAAS and most recently, the Indicator Amino Acid Oxidation IAAO technique.
Ultimately, in vivo protein quality is typically defined as how effective a protein is at stimulating MPS and promoting muscle hypertrophy [ ]. Overall, research has shown that products containing animal and dairy-based proteins contain the highest percentage of EAAs and result in greater hypertrophy and protein synthesis following resistance training when compared to a vegetarian protein-matched control, which typically lacks one or more EAAs [ 86 , 93 , ].
Several studies, but not all, [ ] have indicated that EAAs alone stimulate protein synthesis in the same magnitude as a whole protein with the same EAA content [ 98 ].
For example, Borsheim et al. Moreover, Paddon-Jones and colleagues [ 96 ] found that a cal supplement containing 15 g of EAAs stimulated greater rates of protein synthesis than an cal meal with the same EAA content from a whole protein source.
While important, the impact of a larger meal on changes in circulation and the subsequent delivery of the relevant amino acids to the muscle might operate as important considerations when interpreting this data. In contrast, Katsanos and colleagues [ ] had 15 elderly subjects consume either 15 g of whey protein or individual doses of the essential and nonessential amino acids that were identical to what is found in a g whey protein dose on separate occasions.
Whey protein ingestion significantly increased leg phenylalanine balance, an index of muscle protein accrual, while EAA and NEAA ingestion exerted no significant impact on leg phenylalanine balance. This study, and the results reported by others [ ] have led to the suggestion that an approximate 10 g dose of EAAs might serve as an optimal dose to maximally stimulate MPS and that intact protein feedings of appropriate amounts as opposed to free amino acids to elderly individuals may stimulate greater improvements in leg muscle protein accrual.
Based on this research, scientists have also attempted to determine which of the EAAs are primarily responsible for modulating protein balance. The three branched-chain amino acids BCAAs , leucine, isoleucine, and valine are unique among the EAAs for their roles in protein metabolism [ ], neural function [ , , ], and blood glucose and insulin regulation [ ].
Additionally, enzymes responsible for the degradation of BCAAs operate in a rate-limiting fashion and are found in low levels in splanchnic tissues [ ]. Thus, orally ingested BCAAs appear rapidly in the bloodstream and expose muscle to high concentrations ultimately making them key components of skeletal MPS [ ].
Furthermore, Wilson and colleagues [ ] have recently demonstrated, in an animal model, that leucine ingestion alone and with carbohydrate consumed between meals min post-consumption extends protein synthesis by increasing the energy status of the muscle fiber.
Multiple human studies have supported the contention that leucine drives protein synthesis [ , ]. Moreover, this response may occur in a dose-dependent fashion, plateauing at approximately two g at rest [ 31 , ], and increasing up to 3. However, it is important to realize that the duration of protein synthesis after resistance exercise appears to be limited by both the signal leucine concentrations , ATP status, as well as the availability of substrate i.
As such, increasing leucine concentration may stimulate increases in muscle protein, but a higher total dose of all EAAs as free form amino acids or intact protein sources seems to be most suited for sustaining the increased rates of MPS [ ]. It is well known that exercise improves net muscle protein balance and in the absence of protein feeding, this balance becomes more negative.
When combined with protein feeding, net muscle protein balance after exercise becomes positive [ ]. Norton and Layman [ ] proposed that consumption of leucine, could turn a negative protein balance to a positive balance following an intense exercise bout by prolonging the MPS response to feeding.
In support, the ingestion of a protein or essential amino acid complex that contains sufficient amounts of leucine has been shown to shift protein balance to a net positive state after intense exercise training [ 46 , ].
Even though leucine has been demonstrated to independently stimulate protein synthesis, it is important to recognize that supplementation should not be with just leucine alone.
For instance, Wilson et al. In summary, athletes should focus on consuming adequate leucine content in each of their meals through selection of high-quality protein sources [ ].
Protein sources containing higher levels of the EAAs are considered to be higher quality sources of protein. The body uses 20 amino acids to make proteins, seven of which are essential nine conditionally , requiring their ingestion to meet daily needs. EAAs appear to be uniquely responsible for increasing MPS with doses ranging from 6 to 15 g all exerting stimulatory effects.
In addition, doses of approximately one to three g of leucine per meal appear to be needed to stimulate protein translation machinery. The BCAAs i. However, the extent to which these changes are aligned with changes in MPS remains to be fully explored.
While greater doses of leucine have been shown to independently stimulate increases in protein synthesis, a balanced consumption of the EAAs promotes the greatest increases.
Milk proteins have undergone extensive research related to their potential roles in augmenting adaptations from exercise training [ 86 , 93 ].
For example, consuming milk following exercise has been demonstrated to accelerate recovery from muscle damaging exercise [ ], increase glycogen replenishment [ ], improve hydration status [ , ], and improve protein balance to favor synthesis [ 86 , 93 ], ultimately resulting in increased gains in both neuromuscular strength and skeletal muscle hypertrophy [ 93 ].
Moreover, milk protein contains the highest score on the PDCAAS rating system, and in general contains the greatest density of leucine [ ].
Milk can be fractionated into two protein classes, casein and whey. While both are high in quality, the two differ in the rate at which they digest as well as the impact they have on protein metabolism [ , , ].
Whey protein is water soluble, mixes easily, and is rapidly digested [ ]. In contrast, casein is water insoluble, coagulates in the gut and is digested more slowly than whey protein [ ].
Casein also has intrinsic properties such as opioid peptides, which effectively slow gastric motility [ ]. Original research investigating the effects of digestion rate was conducted by Boirie, Dangin and colleagues [ , , ].
These researchers gave a 30 g bolus of whey protein and a 43 g bolus of casein protein to subjects on separate occasions and measured amino acid levels for several hours after ingestion.
They reported that the whey protein condition displayed robust hyperaminoacidemia min after administration. However, by min, amino acid concentrations had returned to baseline.
In contrast, the casein condition resulted in a slow increase in amino acid concentrations, which remained elevated above baseline after min.
Over the study duration, casein produced a greater whole body leucine balance than the whey protein condition, leading the researcher to suggest that prolonged, moderate hyperaminoacidemia is more effective at stimulating increases in whole body protein anabolism than a robust, short lasting hyperaminoacidemia.
While this research appears to support the efficacy of slower digesting proteins, subsequent work has questioned its validity in athletes. The first major criticism is that Boire and colleagues investigated whole body non-muscle and muscle protein balance instead of skeletal myofibrillar MPS.
These findings suggest that changes in whole body protein turnover may poorly reflect the level of skeletal muscle protein metabolism that may be taking place.
Trommelen and investigators [ ] examined 24 young men ingesting 30 g of casein protein with or without completion of a single bout of resistance exercise, and concluded that rates of MPS were increased, but whole-body protein synthesis rates were not impacted.
More recently, Tang and colleagues [ 86 ] investigated the effects of administering 22 g of hydrolyzed whey isolate and micellar casein 10 g of EAAs at both rest and following a single bout of resistance training in young males.
Moreover, these researchers reported that whey protein ingestion stimulated greater MPS at both rest and following exercise when compared to casein. In comparison to the control group, both whey and casein significantly increased leucine balance, but no differences were found between the two protein sources for amino acid uptake and muscle protein balance.
Additional research has also demonstrated that 10 weeks of whey protein supplementation in trained bodybuilders resulted in greater gains in lean mass 5. These findings suggest that the faster-digesting whey proteins may be more beneficial for skeletal muscle adaptations than the slower digesting casein.
Skeletal muscle glycogen stores are a critical element to both prolonged and high-intensity exercise. In skeletal muscle, glycogen synthase activity is considered one of the key regulatory factors for glycogen synthesis. Research has demonstrated that the addition of protein in the form of milk and whey protein isolate 0.
Further, the addition of protein facilitates repair and recovery of the exercised muscle [ 12 ]. These effects are thought to be related to a greater insulin response following the exercise bout.
Intriguingly, it has also been demonstrated that whey protein enhances glycogen synthesis in the liver and skeletal muscle more than casein in an insulin-independent fashion that appears to be due to its capacity to upregulate glycogen synthase activity [ ].
Therefore, the addition of milk protein to a post-workout meal may augment recovery, improve protein balance, and speed glycogen replenishment.
While athletes tend to view whey as the ideal protein for skeletal muscle repair and function it also has several health benefits. In particular, whey protein contains an array of biologically active peptides whose amino acids sequences give them specific signaling effects when liberated in the gut.
Furthermore, whey protein appears to play a role in enhancing lymphatic and immune system responses [ ].
In addition, α-lactalbumin contains an ample supply of tryptophan which increases cognitive performance under stress [ ], improves the quality of sleep [ , ], and may also speed wound healing [ ], properties which could be vital for recovery from combat and contact sporting events.
In addition, lactoferrin is also found in both milk and in whey protein, and has been demonstrated to have antibacterial, antiviral, and antioxidant properties [ ]. Moreover, there is some evidence that whey protein can bind iron and therefore increase its absorption and retention [ ].
Egg protein is often thought of as an ideal protein because its amino acid profile has been used as the standard for comparing other dietary proteins [ ]. Due to their excellent digestibility and amino acid content, eggs are an excellent source of protein for athletes.
While the consumption of eggs has been criticized due to their cholesterol content, a growing body of evidence demonstrates the lack of a relationship between egg consumption and coronary heart disease, making egg-based products more appealing [ ].
One large egg has 75 kcal and 6 g of protein, but only 1. Research using eggs as the protein source for athletic performance and body composition is lacking, perhaps due to less funding opportunities relative to funding for dairy.
Egg protein may be particularly important for athletes, as this protein source has been demonstrated to significantly increase protein synthesis of both skeletal muscle and plasma proteins after resistance exercise at both 20 and 40 g doses.
Leucine oxidation rates were found to increase following the 40 g dose, suggesting that this amount exceeds an optimal dose [ 31 ]. In addition to providing a cost effective, high-quality source of protein rich in leucine 0.
Functional foods are defined as foods that, by the presence of physiologically active components, provide a health benefit beyond basic nutrition [ ]. According to the Academy of Nutrition and Dietetics, functional foods should be consumed as part of a varied diet on a regular basis, at effective levels [ ].
Thus, it is essential that athletes select foods that meet protein requirements and also optimize health and prevent decrements in immune function following intense training.
Eggs are also rich in choline, a nutrient which may have positive effects on cognitive function [ ]. Moreover, eggs provide an excellent source of the carotenoid-based antioxidants lutein and zeaxanthin [ ].
Also, eggs can be prepared with most meal choices, whether at breakfast, lunch, or dinner. Such positive properties increase the probability of the athletes adhering to a diet rich in egg protein. Meat proteins are a major staple in the American diet and, depending on the cut of meat, contain varying amounts of fat and cholesterol.
Meat proteins are well known to be rich sources of the EAAs [ ]. Beef is a common source of dietary protein and is considered to be of high biological value because it contains the full balance of EAAs in a fraction similar to that found in human skeletal muscle [ ].
A standard serving of Moreover, this 30 g dose of beef protein has been shown to stimulate protein synthesis in both young and elderly subjects [ ]. In addition to its rich content of amino acids, beef and other flesh proteins can serve as important sources of micronutrients such as iron, selenium, vitamins A, B12 and folic acid.
This is a particularly important consideration for pregnant and breastfeeding women. Ultimately, as an essential part of a mixed diet, meat helps to ensure adequate distribution of essential micronutrients and amino acids to the body.
Research has shown that significant differences in skeletal muscle mass and body composition between older men who resistance train and either consume meat-based or lactoovovegetarian diet [ ]. Over a week period, whole-body density, fat-free mass, and whole-body muscle mass as measured by urinary creatinine excretion increased in the meat-sourced diet group but decreased in the lactoovovegetarian diet group.
These results indicate that not only do meat-based diets increase fat-free mass, but also they may specifically increase muscle mass, thus supporting the many benefits of meat-based diets. A diet high in meat protein in older adults may provide an important resource in reducing the risk of sarcopenia.
Positive results have also been seen in elite athletes that consume meat-based proteins, as opposed to vegetarian diets [ ]. For example, carnitine is a molecule that transports long-chain fatty acids into mitochondria for oxidation and is found in high amounts in meat.
While evidence is lacking to support an increase in fat oxidation with increased carnitine availability, carnitine has been linked to the sparing of muscle glycogen, and decreases in exercise-induced muscle damage [ ].
Certainly, more research is needed to support these assertions. Creatine is a naturally occurring compound found mainly in muscle. Vegetarians have lower total body creatine stores than omnivores, which demonstrates that regular meat eating has a significant effect on human creatine status [ ].
Moreover, creatine supplementation studies with vegetarians indicate that increased creatine uptake levels do exist in people who practice various forms of vegetarianism [ ]. Sharp and investigators [ ] published the only study known to compare different supplemental powdered forms of animal proteins on adaptations to resistance training such as increases in strength and improvements in body composition.
Forty-one men and women performed a standardized resistance-training program over eight weeks and consumed a daily 46 g dose of either hydrolyzed chicken protein, beef protein isolate, or whey protein concentrate in comparison to a control group.
All groups experienced similar increases in upper and lower-body strength, but all protein-supplemented groups reported significant increases in lean mass and decreases in fat mass. Meat-based diets have been shown to include additional overall health benefits.
Some studies have found that meat, as a protein source, is associated with higher serum levels of IGF-1 [ ], which in turn is related to increased bone mineralization and fewer fractures [ ]. A highly debated topic in nutrition and epidemiology is whether vegetarian diets are a healthier choice than omnivorous diets.
One key difference is the fact that vegetarian diets often lack equivalent amounts of protein when compared to omnivorous diets [ ].
However, with proper supplementation and careful nutritional choices, it is possible to have complete proteins in a vegetarian diet.
Generally by consuming high-quality, animal-based products meat, milk, eggs, and cheese an individual will achieve optimal growth as compared to ingesting only plant proteins [ ]. Research has shown that soy is considered a lower quality complete protein.
Hartman et al. They found that the participants that consumed the milk protein increased lean mass and decreased fat mass more than the control and soy groups. Moreover, the soy group was not significantly different from the control group. Similarly, a study by Tang and colleagues [ 86 ] directly compared the abilities of hydrolyzed whey isolate, soy isolate, and micellar casein to stimulate rates of MPS both at rest and in response to a single bout of lower body resistance training.
These authors reported that the ability of soy to stimulate MPS was greater than casein, but less than whey, at rest and in response to an acute resistance exercise stimulus. While soy is considered a complete protein, it contains lower amounts of BCAAs than bovine milk [ ]. Additionally, research has found that dietary soy phytoestrogens inhibit mTOR expression in skeletal muscle through activation of AMPK [ ].
Thus, not only does soy contain lower amounts of the EAAs and leucine, but soy protein may also be responsible for inhibiting growth factors and protein synthesis via its negative regulation of mTOR.
When considering the multitude of plant sources of protein, soy overwhelmingly has the most research. Limited evidence using wheat protein in older men has suggested that wheat protein stimulates significantly lower levels of MPS when compared to an identical dose 35 g of casein protein, but when this dose is increased nearly two fold 60 g this protein source is able to significantly increase rates of myofibrillar protein synthesis [ ].
As mentioned earlier, a study by Joy and colleagues [ 89 ] in which participants participated in resistance training program for eight weeks while taking identical, high doses of either rice or whey protein, demonstrated that rice protein stimulated similar increases in body composition adaptations to whey protein.
The majority of available science has explored the efficacy of ingesting single protein sources, but evidence continues to mount that combining protein sources may afford additional benefits [ ].
People who are training or racing at peak levels may find it challenging to consume enough food for their energy requirements without causing gastrointestinal GI discomfort, especially immediately before an important workout or race. For example, the ISSA highlights the importance of hydration and carbohydrate loading for competitive swimmers.
At the same time, it emphasizes consuming easily digestible carbohydrates, such as bananas and pasta, prior to events to avoid GI discomfort.
Athletes may need to work with a sports nutritionist, preferably a registered dietitian , to ensure they consume enough calories and nutrients to maintain their body weight, optimize performance and recovery, and plan a timing strategy that suits their body, sport, and schedule.
Athletes need to eat a healthy and varied diet that meets their nutrient requirements. Choosing whole grains and other fiber -rich carbohydrates as part of a daily diet generally promotes health.
However, immediately prior to and during intense trainings and races, some athletes may prefer simpler, lower fiber carbohydrates to provide necessary fuel while minimizing GI distress. The following is an example of what an athlete might eat in a day to meet their nutritional needs.
Breakfast: eggs — either boiled, scrambled, or poached — with salmon , fresh spinach , and whole grain toast or bagel. Lunch: stir-fry with chicken or tofu, brown rice , broccoli , green beans , and cherry tomatoes cooked in oil.
Dinner: a baked sweet potato topped with turkey, bean chili, or both, served with a watercress , peppers, and avocado salad drizzled with olive oil and topped with hemp seeds. Snacks are an important way for athletes to meet their calorie and nutrition needs and stay well fueled throughout the day.
Options include:. Athletes need to plan their diet to optimize their health and performance. They should consider their calorie and macronutrient needs and ensure they eat a varied diet that provides essential vitamins and minerals. Hydration and meal timing are also vital for performing well throughout the day.
Some athletes may choose to take dietary supplements. However, they should be mindful of safety and efficacy issues and ensure that their sporting association allows them. Both amateur and professional athletes may benefit from consulting with a sports nutritionist to help them plan the optimal diet for their individual needs and goals.

Medically reviewed by Alissa Palladino, MS, RDN, LD, CPT , Nutrition , Personal Training — By Louisa Richards on April 20, Importance Macronutrients Other nutrients Calories Meal timing Tailoring nutrition Example meals Summary Athletes will have different nutritional needs compared with the general public.
Why is nutrition important? Micronutrients, supplements, and hydration. Sufficient calories. Meal timing.
For athletes, maintaining Macronutrisnt proper Macronitrient balance is crucial in order to achieve peak Macronutrient Optimization for Sports and Performance and optimize their training. The right combination of macronutrients, including carbohydrates, Performancw, and fats, provides the body with the Mood enhancer diet and essential nutrients needed for optimal athletic performance. In this article, we will explore the importance of macronutrient balance for athletes and how it can enhance their overall performance and well-being. Macronutrients are the three main components of our diet that provide energy to the body. These include carbohydrates, proteins, and fats. Each macronutrient plays a unique role in fueling the body and supporting various physiological functions.
Macronutrient Optimization for Sports and Performance -
Recommendations suggest that for sustained or intermittent exercise longer than 90 minutes, athletes should consume 10—12 g of carbohydrate per kg of body mass BM per day in the 36—48 hours prior to exercise. We caught up with Richard Allison, Sports Performance Nutritionist, who gave some insightful pieces of information with regards to fuelling for performance.
Preparation is the key to match day, and this starts the day before your match. Often referred to as Match Day -1, the primary aim is to maximise both muscle and liver glycogen to ensure adequate carbohydrate availability to effectively prepare and recover for the match.
Carbohydrates are the primary fuel source for muscles during high-intensity activities; it is therefore a key macronutrient when preparing players for match play. It is well documented that exercise performance is greatly influenced by nutrition.
The key factor in coping with the heavy demands of exercise faced by elite athletes seems to be carbohydrate intake. Players who begin a match with low glycogen stores will typically cover less distance and complete less high-speed runs, particularly in the second half, which can have huge ramifications on individual and potentially team performance and may contribute to the outcome of the match.
This emphasises the importance of prioritising a balanced diet that will improve an athletes physical performance on gameday. Carbohydrates are essential for optimal match day performance as it is the primary fuel for muscle during high intensity activities.
It is the key macronutrient for proper preparation for match day. Below is an example of what a typical athletes game day nutrition should look like with Kick Off according to Richard Allison.
From the carbohydrate loading to having a balanced healthy diet in the weeks and days building up to gameday. With proper hydration, your body will be able to perform at its best.
Hydration for athletes is essential to maintain normal blood circulation because this aids the delivery of nutrients and oxygen to every working muscle in the body. As water is involved in the majority of chemical reactions involved in athletic performance it is therefore important that athletes are hydrated before, during and after physical activity to achieve their maximal physical performance.
Hydration enhances your motor neurons. Carbohydrates are typically the preferable fuel source for many athletes, particularly for high intensity and long duration exercise.
This is because they supply ample glycogen storage and blood glucose to fuel the demands of exercise. To maintain liver and muscle glycogen stores, athletes will need different amounts of carbohydrates depending on their exercise volume.
For example, an athlete weighing kg who performs high volume intense training would look to consume roughly 1,—1, g of carbohydrates.
Protein also plays an essential role in sports nutrition, as it provides the body with the necessary amount of amino acids to help build and repair muscles and tissues. Athletes doing intense training may benefit from ingesting more than two times the recommended daily amount RDA of protein in their diet.
For example, the dietary reference intake for adult females is 46 g, and for adult males — 56 g. That is why it may be beneficial for athletes to consume nearer to 92 g and g of protein, respectively.
The ISSA suggests that many athletes can safely consume 2 g of protein per 1 kg of body weight daily, compared with the RDA of 0.
The ISSN also notes that optimal protein intake may vary from 1. Higher amounts of protein can help athletes avoid protein catabolism and slow recovery, which the ISSN notes can contribute to injuries and muscle wasting over time. For moderate amounts of intense training, an athlete should consume 1.
For high volume intense training, the ISSN suggests 1. Healthy protein sources include:. Fats are essential in the diet to maintain bodily processes, such as hormone metabolism and neurotransmitter function. Including healthy fats in the diet also helps satiety and can serve as a concentrated fuel source for athletes with high energy demands.
Some athletes may choose to eat a ketogenic diet and consume higher amounts of fats. Healthy fat sources include oily fish , olive oil , avocados , nuts, and seeds.
Athletes should ensure they consume the essential vitamins and minerals they need to support their general health and sports performance.
People can usually achieve adequate intakes of essential vitamins and minerals by eating a varied, balanced diet. Some athletes may choose to take vitamin or mineral supplements or ergogenic aids, such as creatine. The ISSN recommends that consumers evaluate the validity and scientific merit of claims that manufacturers make about dietary supplements.
There is little evidence to support the efficacy or safety of many dietary supplements, including:. However, scientists have shown that other ergogenic aids, such as caffeine and creatine monohydrate, are safe and effective for athletes.
It is important to be aware that some athletic associations ban the use of certain nutritional supplements. Moreover, athletes should ensure they maintain adequate hydration. Given that sweat losses are a combination of fluids and electrolytes, such as sodium and potassium, athletes may choose to and benefit from using sports drinks, milk , or both to meet some of their hydration needs.
The ISSN suggests that athletes training intensely for 2—6 hours per day 5—6 days of the week may burn over — calories per hour while exercising. As a result, athletes engaging in this level of activity may require 40—70 calories per 1 kg of body weight per day, compared with the average less active individual, who typically requires 25—35 calories per 1 kg of body weight daily.
According to the ISSN, athletes weighing 50— kg may require 2,—7, calories per day. It also notes that athletes weighing — kg may need to consume 6,—12, calories daily to meet training demands. The timing and content of meals can help support training goals, reduce fatigue, and help optimize body composition.
Guidelines for the timing and amount of nutrition will vary depending on the type of athlete. For example, the ISSN advises strength athletes consume carbohydrates and protein or protein on its own up to 4 hours before and up to 2 hours after exercise.
The American College of Sports Medicine ACSM also notes the importance of consuming protein both before and after exercise for strength athletes. By contrast, endurance athletes would need to consume mostly carbohydrates and a small amount of protein roughly 1—4 hours before exercise.
Both the ISSN and ACSM emphasize the role of meal timing in optimizing recovery and performance and recommend athletes space nutrient intake evenly throughout the day, every 3—4 hours. Recovery : Consuming protein post-exercise aids in muscle recovery, helping to minimize muscle soreness and promote optimal performance in subsequent workouts.
Sources : Lean meats, poultry, fish, eggs, dairy products, legumes, and plant-based protein sources like tofu and tempeh are excellent options for meeting protein needs. Carbohydrates: The Body's Primary Energy Source Immediate Energy : Carbohydrates are broken down into glucose, which is used as the primary source of energy for muscles during high-intensity exercise.
Glycogen Stores : Consuming carbohydrates replenishes glycogen stores in muscles and the liver, which are essential for sustained energy during prolonged physical activity.
Complex vs. Simple Carbs : Complex carbohydrates like whole grains, fruits, and vegetables provide sustained energy, while simple carbohydrates from sources like fruits or sports drinks offer quick energy during intense exercise. Fats: An Additional Source of Energy Long-Term Energy : While carbohydrates are the primary fuel for high-intensity exercise, fats become a significant energy source during lower-intensity, prolonged activities.
Essential Fatty Acids : Fats provide essential fatty acids necessary for various bodily functions, including hormone production and cell membrane health. Sources : Include sources of healthy fats like avocados, nuts, seeds, olive oil, and fatty fish in your diet for a well-rounded approach to sports nutrition.
Many sports dietitians find themselves working with Perfirmance array of different sports and advising athletes Macronuhrient a wide Antioxidant foods for managing stress of needs. Macronufrient athletes rely on Perfor,ance Macronutrient Optimization for Sports and Performance system, while Macronutrient Optimization for Sports and Performance athletes primarily use Staying hydrated phosphagen Macronutrient Optimization for Sports and Performance Macronutroent fastest Spports for the body to resynthesize ATP. Another major difference between these two groups of athletes is the amount of energy they expend. Regardless of gender, age, or sport, endurance athletes burn a significant amount of calories during continuous distance training sessions that may last four hours and more. For them, keeping calorie intake high day after day is necessary. Power athletes, on the other hand, typically have lower calorie that may vary based on gender, age, sport, and goals.
