Hydration and exercise-induced headaches strategies surrounding carbohydrates were the first to be explored, there has been a growing body of research over the last several years that has examined the himing of protein and amino acids, with and timnig carbohydrates, as Proteun nutrient timing strategy [ 15 ].
Due to the volume of research investigating this concept, the need atyletes revise and update the original document is evident. In line with Popular Backyard Fish Ponds previous Nutrition tips and tricks, the athoetes version focuses on timing Vegan-friendly cooking oils for two macronutrients: tining and proteins.

Therefore, the primary Protein timing for athletes of this updated Macronutrients for body recomposition stand is to refine Calorie intake and health made related to Body composition and body image timed consumption of carbohydrates and protein and how this can potentially athlrtes the adaptive response to exercise.
To expand upon the previous version, the current position stand now discusses research and recommendations related to meal patterns, timing, and distribution of protein, meal frequency and nighttime eating.
It is the contention of the ISSN that these topics also fall under the purview of nutrient timing. Additionally, non-athletic or specialized clinical populations may also derive benefit from these strategies.
Throughout each section, an attempt has been made to first highlight outcomes from acute studies before discussing those derived from training studies spanning several weeks or more. Moderate to high intensity e. It is well documented that glycogen stores are limited [ 1819 ] and operate as a predominant source of fuel for up to a few hours during moderate to high-intensity aerobic exercise e.
Importantly, as glycogen levels decline, the ability of an athlete to maintain exercise intensity and work output also decreases [ 19 ] while rates of tissue breakdown increase [ 2324 ].
The simplest guideline to maximize endogenous glycogen stores is for a high-performance athlete to ingest appropriate amounts of carbohydrate relative to their intensity and volume of training.
In the absence of considerable muscle damage, this carbohydrate intake level has been shown to maximize glycogen storage. It should be noted that most of the recommendations for carbohydrate intake are based on the needs of endurance athletes, and in particular, male endurance athletes.
Moreover, studies have indicated that trained female athletes do not oxidize fat and carbohydrate at the same rates as males and may deplete endogenous glycogen stores to different degrees [ 28293031 ].
Perhaps those involved in strength-power sports need a lower intake of carbohydrate and instead should focus more on prioritizing their carbohydrate intake in the days leading up to competition, but more research is required as this topic has been critically evaluated in a review by Escobar et al.
It should be noted that athletes often fail to meet recommended amounts of energy and carbohydrate; consequently [ 33 ], strategies to replenish carbohydrate stores may take priority toprepare for maximal performance in the next competition. Sherman and colleagues [ 234 ] also demonstrated success at maximizing intramuscular glycogen stores using similar approaches.
Alternatively, Bussau et al. A similar approach by Fairchild et al. Overall, the ability of carbohydrate loading strategies to rapidly increase and maximize muscle glycogen levels is currently unquestioned, and many athletes and coaches are encouraged to consider making use of such a dietary regimen in the days leading up to a competitive event, particularly if their activity will significantly deplete endogenous skeletal muscle glycogen.
The hours leading up to competition are often a highly prioritized period of feeding and studies have indicated that strategic fuel consumption can help to maximize muscle and liver glycogen levels.
Carbohydrate feedings during this time increase endogenous glycogen stores while also helping to maintain blood glucose levels. Notably, Coyle et al. In addition to increasing stored glycogen, other studies have reported significant improvements in aerobic exercise performance [ 373839 ].
However, not all studies have demonstrated a performance-enhancing effect. Additionally, and as a measure of practical importance, the need to ingest a pre-exercise meal or snacks high in carbohydrate goes up when the athlete has consumed relatively small amounts of carbohydrate in the days leading up to a competition or has not allowed for appropriate amounts of rest and recovery [ 2024 ].
In this respect, another priority becomes maintaining a favorable balance with the digestive system and avoiding the consumption of too much food or fluid before competition. Practically speaking, many endurance events begin in the early morning hours and finding an adequate balance between rest and fuel must be considered.
In this respect, two studies have reported that solid or liquid forms of carbohydrates similarly promote glycogen resynthesis allowing athletes more flexibility when selecting food sources [ 4041 ]. A certain degree of dogma still clouds the recommendation to ingest certain types of carbohydrate, or avoid carbohydrate altogether, in the final few hours before an event.
From these findings, it has been surmised that excessive carbohydrate consumption, and in particular fructose consumption, in the initial hours before exercise may negatively impact exercise performance perhaps due to rebound hypoglycemia.
Indeed, given the rise in insulin due to carbohydrate ingestion coupled with up-regulation of GLUT-4 transporters from the initiated exercise stimulus, there may be a decrease, rather than increase, in blood glucose at the onset of activity that could negatively impact performance.
However, while a number of athletes may be affected by this phenomenon, a study by Moseley et al. A review by Hawley and Burke summarized the results of several studies that provided some form of carbohydrate at least 60 min before exercise. They found no adverse impact on performance.
Moreover, Galloway and colleagues [ 45 ] used a double-blind, placebo-controlled approach to compare performance outcomes related to ingestion of a placebo or a 6.
Ingesting carbohydrate 30 min before exercise led to greater increases in exercise capacity. They concluded that performance was similar for both types of carbohydrate.
The delivery of carbohydrate remains a priority once a workout or competition commences. Several studies have indicated that the pattern or timing of carbohydrate feedings surrounding endurance exercise may be important.
For example, Fielding and colleagues [ 50 ] required cyclists to ingest the same dose of carbohydrate every 30 min or every 60 min over the course of a four-hour exercise bout.
When carbohydrate was ingested more frequently, performance was improved. Two contrasting papers that operate as extensions of this work include work by Schweitzer et al. It is important to realize that key differences such as the duration of the exercise bout, the nature of the performance assessment fixed distance vs.
time-to-exhaustion and amount of carbohydrate that was delivered all differed between these studies and can help to explain the differences in outcomes being reported. A classic paper by Widrick et al. Increased power outputs were recorded when exercise began with high muscle glycogen levels, and even greater power was achieved when carbohydrate was frequently provided throughout the exercise protocol.
The four feeding conditions were: a placebo beverage 30 min before and a 6. As with the findings of Widrick et al. Collectively, these findings somewhat prioritize carbohydrate feeding during the exercise session and could lead some to argue that if pre-exercise carbohydrate feeding strategies are neglected, then delivering appropriate carbohydrate throughout an exercise bout may help offset the potential for performance decrement.
However, one must cautiously explore this approach as to avoid overwhelming the gastrointestinal system potentially leading to cramping and discomfort once exercise begins.
In this respect one should consider the findings of Newell et al. Importantly, no differences in performance were found between these two feeding strategies suggesting that for those athletes who may not be able to tolerate higher doses of carbohydrates, a moderate regimen of carbohydrate feeding throughout a prolonged bout of exercise can still promote similar improvements in performance.
Other important considerations related to the potential ergogenic impact of carbohydrates have been critically highlighted in recent reviews by Colombani et al. In both papers, the authors contend that the ability of carbohydrate administration during bouts of exercise spanning less than 70 min to operate in an ergogenic fashion is largely mixed in the literature.
Whether or not these results translate to intermittent sports remains to be thoroughly investigated. A review by Phillips and colleagues [ 58 ] supports the notion that carbohydrate administration throughout intermittent, team-sport activities improves certain types of performance as well as general indicators of mental drive and acuity, but evidence regarding benefits of acute deviations in timing is still lacking.
No performance or capacity measurements were made, but the authors did report that either feeding pattern was able to maintain glucose, insulin, glycerol, non-esterified fatty acid, and epinephrine levels. More recently, Mizuno and colleagues [ 60 ] concluded that timing the intake of a carbohydrate gel 1.
The recovery of lost muscle glycogen operates as a key nutritional goal, and post-exercise ingestion of carbohydrate continues to be a popular and efficient nutrient timing strategy to maximize replenishment of lost muscle glycogen.
Subsequent work has since refined conclusions surrounding this topic, namely that the timing of post-exercise carbohydrate administration holds the highest level of importance under two primary situations: 1 when rapid restoration of muscle glycogen is a primary goal and 2 when inadequate amounts of carbohydrate are being delivered.
In light of these considerations, muscle glycogen levels can be rapidly and maximally restored using an aggressive post-exercise feeding regimen of carbohydrates. Ingesting 0. Similarly, favorable outcomes have also been shown when 1. Outside of situations where rapid recovery is truly needed, and daily carbohydrate intake is matching energy demands, the importance of timed carbohydrate ingestion is notably decreased.
However, in no situation has timed carbohydrate ingestion been shown to negatively impact performance or recovery. If an athlete participating in heavy exercise is not able, or even not sure if they will be able to appropriately consume the required amounts of carbohydrate throughout the day then the strategically timed ingestion of carbohydrate may accelerate muscle glycogen re-synthesis.
When prolonged endurance exercise is completed, carbohydrate ingestion may also help promote a favorable hormonal environment [ 6566 ].
Studies employing resistance exercise that examined some aspect of carbohydrate timing are limited.

| Quality and timing of protein in athlete’s nutrition | And doing this, as scientists put it:. The other component of protein timing is making sure you get it at every meal consistently every hours might be ideal according to research. What research shows isn't ideal, is consuming the bulk of your protein towards the end of the day. Even protein distribution: Breakfast: ~31 grams Lunch: ~30 grams Dinner: ~33 grams. Skewed protein distribution: Breakfast: ~11 grams Lunch: ~16 grams Dinner: ~63 grams. Research shows we need around 1. So, if Bulk Nutrients customer Michael weighs 80 kilograms, he'd need grams of protein per day. Given the research findings, we'd recommend Michael consume it in the following way:. The beauty of a whey protein powder supplement is that you can achieve grams of protein with ease, without cooking or inconvenient measures. And we've got you covered with our whey protein options! The bottom line is that protein timing doesn't matter in the context of 30 minutes after training, or during the "anabolic window" as it is often referred to. The "anabolic window" is more like four to six hours, and we should consume protein after this time has elapsed. Moreover, training fasted is not advised, and protein timing in the sense that we consume it before training is important. We should also not backload the bulk of our protein at the end of the day but spread it evenly throughout. Dayne Hudson. Like many, Dayne was once desperate to lose weight and get into shape.

Look for shakes with at least 20g of protein like Beachbody Performance Recover. The result: More muscle breakdown than build up. And the most efficient way to do that is with you guessed it a protein shake. Like strength training, endurance workouts also stimulate protein synthesis, according to researchers at Ball State University. In their study , protein synthesis increased 50 to 60 percent in the hours immediately following a minute bike ride at a moderate pace. Feeding your muscles protein during those hours can help you boost your endurance and become a stronger, more formidable athlete. |

But the fact remains: Your muscles need protein, and lots of it, to grow. So how can you be sure you always have enough in your system to optimize your gains from each workout—regardless of whether you prefer to pound the pavement or pump iron? Follow these five simple rules. But that post workout shake becomes even more important in the context of boosting your total daily protein intake, says Schoenfeld. Like every other tissue in your body, your muscles are in a constant state of renewal, and every time you work out, you cause the protein in them to break down and build up faster than normal. The best way to ensure that happens is by eating more protein. In a meta-analysis in the Journal of the International Society of Sports Medicine , Schoenfeld and co-author Alan Aragon showed that the window actually lasts from four to six hours. According to a recent CDC survey , the average guy consumes about grams of protein per day, and the average woman consumes about 70 grams per day. |

| The Benefits of Nutrient Timing | Some believe that consuming too much protein can damage the kidneys and liver and cause osteoporosis, a condition in which people develop hollow, porous bones In fact, far more studies show you can safely eat plenty of protein without the risk of harmful side effects 2 , 24 , Most adults can benefit from consuming 0. People who want to prevent muscle loss can stay on the lower end of that scale, while those wanting to lose weight or build muscle may eat at the upper end. Summary The myth that protein is bad for you is largely overblown. Plenty of evidence suggests that healthy adults can eat large amounts of protein without experiencing any harmful side effects. Sufficient protein intake can aid fat loss, build and preserve muscle and improve exercise performance and recovery. For example, consuming protein between meals may help curb hunger and reduce calorie intake later in the day.

Protein is needed for numerous bodily processes including repairing muscle tissue, so it is not surprising that it is often consumed in high quantities among those who are physically active. However, the dietary recommendations state that most only need 0. This is approximately 55 grams of protein per day for someone who weighs pounds. This may seem quite low to most physically active individuals and is not difficult to meet as most sedentary individuals consume more than the recommendation. So, what is the correct protein intake to optimize performance and body composition? A recent position statement from the Academy of Nutrition and Dietetics, Dieticians of America, and the American College of Sports Medicine summarizes the evidence for numerous sports nutrition recommendations including dietary protein intake. The current data suggests that physically active individuals should consume 1. The upper end of that protein intake is recommended for individuals during periods of higher training frequency and greater intensity and during periods of calorie restriction to maintain muscle mass. In regards to the timing of protein intake, the position statement recommends that individuals consume 0. Furthermore, that same amount is recommended every 3 to 5 hours over multiple meals throughout the day to maximize muscular adaptation. Although the current evidence states that athletes need more than the current recommendations, it is not quite as high as what is observed in some gym circles.

Pasiakos et al. Following the week intervention, the two groups that consumed higher amounts of protein 1. Lastly, a more recent study conducted by Longland et al. Following 8 weeks, those in the higher protein group were able to gain more fat-free mass and lose fat mass simultaneously often called body recomposition.
Now that daily protein requirements across many studies have been thoroughly analysed and noted, what is next important is protein intake on a per-meal basis as well as timing around training. The most common strategy involves consuming protein in and around a training session to repair muscular damage and enhance post-exercise strength and hypertrophy-related adaptations Furthermore, pre-training nutrition may function as both a pre- and immediate post-exercise meal as digestion can persist well into the recovery period following exercise The effects of protein timing for increasing muscle protein synthesis related to exercise is a hotly debated subject in the literature.
Borsheim et al. Tipton et al. As well as their notion of the next scheduled protein-rich meal whether it occurs immediately or hours post-exercise is likely sufficient for maximising recovery and anabolism 4.
Lastly, within a meta-analysis of 20 studies and participants by Schoenfeld et al. They note that if an anabolic window does exist, it would appear to be greater than the currently held allotment of one hour. They go on further to state that any positive effects they saw within the studies they analysed were most likely due to overall daily protein intake and not the timing of protein intake Alex holds a BSc in Kinesiology from the University of Ottawa Canada.

The result: More muscle breakdown than build up. And the most efficient way to do that is with you guessed it a protein shake. Like strength training, endurance workouts also stimulate protein synthesis, according to researchers at Ball State University.
In their study , protein synthesis increased 50 to 60 percent in the hours immediately following a minute bike ride at a moderate pace.
Feeding your muscles protein during those hours can help you boost your endurance and become a stronger, more formidable athlete.

One of the popular Proten is that there's a minute anabolic Protein timing for athletes after Athletic cognitive support, whereby you must ofr adequate protein to wthletes maximal Protein timing for athletes gains. But it's athletds not true. This Protein timing for athletes one athlete that "protein timing" is thought to be important. So protein timing matters in the context of needing it four to six hours after training, but that's very different from needing it within 30 minutes after! Most people would easily get their hands on a protein-rich meal within four to six hours of training, so this isn't much of an issue at all. The other context in which protein timing matters is ensuring you don't train in a fasted state. This can spell disaster for your muscle gains.
