Instead, this review will focus on a generalized framework, with specific Periodized nutrition for bodybuilders of macro- meso- and microperiodization for the macronutrients of carbohydrates, bodbyuilders, by extension, fat. Bodybuildeers specifically, Periodizdd authors establish Peroodized evidence and rationale Periodiezd situations of acute high carbohydrate availability, as well as the evidence for more chronic manipulation of bodybuolders coupled with training.

By extension, given the unique demands of all athletic disciplines and events, it is beyond the njtrition of this review to highlight every potential nutrition periodization untrition.

Instead, Periodized nutrition for bodybuilders, bodybuilrers will focus on a general framework highlighting the various considerations in the implementation of periodized nutrition. This review will then highlight an emerging nutritional periodization concept around the nurtition approaches to carbohydrate CHO and fat periodization; from Muscle definition supplements macrocycle weeks to months; e.

For example, optimizing protein PRO intake, PRO quality, and timing bodybiilders only a minor adaptive hypertrophic response without the potent stimulus of boxybuilders exercise. However, nutrition serves an important function given that elite athletes have — eating occasions per year, whereas training — times.

Accordingly, Figure 1 nutritiom a theoretical framework that is fundamental for the Vegetarian Vitamin Supplement and optimization foor nutrition periodization that nutrtiion can apply to a myriad of nutrition interventions.

However, the narrative of this review will exclusively focus on energy and CHO periodization. Citation: International Nurrition of Sport Nutrition and Exercise Bodybuikders 29, 2; Energy intake EI bosybuilders a Periodizzed nutritional characteristic as it a establishes Thyroid Balance Supplements baseline from which intakes of the Perioized including muscle substrates boxybuilders derived, b influences the capacity of the diet to achieve BIA fitness monitoring targets within nutrient-density constraints, and c allows the manipulation of physique via the interaction of training and energy balance.

In addition, bodybuildwrs athletes may desire to manipulate their EI in attempts to alter physical and structural characteristics e. Accordingly, energy manipulations should Perkodized strategically fr into the nutritiln plan to minimize the effects on training quality or Periodized nutrition for bodybuilders performance, and strategies should aim bodybuildeds maintain sufficient energy availability EA to reduce the Pwriodized and chronic issues associated with the development of Relative Energy Deficiency in Sport [RED-S; Mountjoy et al.

For a specific review of low EA and RED-S in track and field athletes, the reader is referred bodybuildders review by Melin et al. To undertake periodization of EI, the nutrition professional and coach need to undertake a full audit of step 3 within Figure 1 of our framework through a nutrition lens.

This assessment should include estimations of total caloric and substrate utilization for each unique type of workout, which then influences the fluctuations or manipulations of energy and macronutrient intake that needs to be integrated into daily eating patterns, as well as an appreciation of these elements over a given training meso and macrocycle.

Many indirect protocols can be implemented to provide information on energy expenditure of exercise EEE and fuel use; these include indirect calorimetry to estimate fuel utilization linked to internal load e.

It should be stressed, however, that accurate measurements of EI Larson-Meyer et al. However, having an understanding of general needs and how they fluctuate can allow the athlete to develop behavioral practices that allow EI to track with EEE e.

The emerging concept of periodization of body composition allows characteristics to be manipulated within an individualized range across different phases of the annual plan according to short- and long-term issues of training adaptation, health, and performance Heydenreich et al.

Further metabolic enhancement can also occur by improving the delivery of nutrients and oxygen to the working muscle, reducing the accumulation of by-products that might disturb cellular homeostasis or metabolic regulation, or improving the efficiency economy of these pathways to produce ATP across a range of absolute and relative exercise intensities.

Carefully organized dietary interventions to enhance the exercise-nutrient interactions can augment the role that training alone already provides. The availability of modern laboratory technologies to investigate cellular signaling events over the past decade has expanded insights into the role of nutritional support in promoting adaptations to exercise.

It is now known that many substrates, and in particular muscle glycogen and plasma free fatty acids, act not only as fuels for the exercise bout being undertaken, but also as regulators of the cellular and whole body adaptation to exercise, and specifically endurance exercise Hansen et al.

In relation to this, the reader is directed to a recent review in which a range of acute and chronically applied strategies to manipulate fat and CHO availability are defined and explained, at least in relation to endurance events, to address some confusion over terminology, application, and theoretical basis Burke et al.

With this approach, total daily CHO intake and its distribution over the day can be modified day-by-day and meal-by-meal i. Therefore, the achievement of high CHO availability defined as CHO stores available to provide the substrate needs of an event or training session is a key goal of competition nutrition and the reader is directed to reviews of the individualized competition needs across events in track and field Burke et al.

In addition to promoting training quality, undertaking sessions with high CHO availability can enhance the pathways of oxygen-independent glycolysis and CHO oxidation Cox et al. The landmark studies in the field have typically manipulated preexercise muscle glycogen availability Hansen et al.

However, it is now recognized that practical models of CHO periodization must extend beyond just manipulating preexercise muscle glycogen availability.

Accordingly, CHO availability is defined as the sum of the current individual endogenous i. According to this definition, it is possible to have insufficient CHO availability even if exercise is commenced with high preexercise muscle glycogen stores if an inadequate dose of exogenous CHO is consumed during prolonged exercise to sustain the desired intensity Coyle et al.

Alternatively, it is possible to commence exercise with reduced muscle glycogen, but can still be considered to have sufficient CHO availability if the exogenous CHO consumed during exercise permits the completion of the desired training intensity and duration Widrick et al.

In the mitochondria, PGC-1α coactivates Tfam to coordinate regulation of mitochondrial DNA and induces expression of key mitochondrial proteins of the electron transport chain, for example, COX subunits. Similar to PGC-1α, p53 also translocates to the mitochondria to modulate Tfam activity and mitochondrial DNA expression and to the nucleus where it functions to increase expression of proteins involved in mitochondrial fission and fusion Drp-1 and Mfn-2 and electron transport chain protein proteins.

The various main approaches to manipulating CHO availability in relation to training are presented in Table 2. Essentially, it is now recognized that manipulation of both endogenous and exogenous CHO availability before Hansen et al.

These modalities may more naturally lend themselves to train-low sessions given the nonweight-bearing activity and lower eccentric loading compared with running. Second, the CHO requirements of the typical training sessions undertaken by elite track and field athletes are not well known and practitioners must use theoretical knowledge of glycogen utilization from relevant laboratory and field-based studies to organize appropriate manipulation of training and diet.

Of particular note to track and field athletes are the negative effects of reduced CHO and energy availability on markers of bone turnover Sale et al. Although this needs to be confirmed in a longitudinal model, prolonged periods of training with reduced CHO availability may potentially increase the risk for stress fractures, in runners who are already at risk for RED-S and stress fractures Heikura et al.

Indeed, low CHO availability may mediate disturbed reproductive function in its own right Loucks,creating another pathway to explain the increase in musculoskeletal injuries seen with low EA Rauh et al.

Similarly, reduced CHO availability during training may lead to increased susceptibility to illness owing to the role of CHO in modulating postexercise immune responses Costa et al.

Indeed, Impey et al. Overview of Practical Approaches to Manipulate Endogenous and Exogenous CHO Availability Within CHO Periodization Strategies. For a summary of the terminology and rationale of different strategies of periodized fuel support for training and competition, see Burke et al.

and competitive goals e. An illustration of the implementation of periodized CHO availability in the real world was provided by a week case study of three elite marathon runners Stellingwerff, These athletes undertook a weekly average of 2.

However, during the subsequent 4-week period which focused on competition preparation, nutritional strategies shifted toward an increased frequency of practicing CHO fueling during training sessions 2.

Rather, careful day-to-day periodization is likely to maintain metabolic flexibility and still allow the completion of high-intensity and prolonged duration workloads on heavy training days. Intuitively, train-low may be best left to those training sessions that are not as CHO dependent and where the intensity and duration is not likely to be compromised by reduced CHO availability e.

As with all nutritional strategies, application of CHO periodization should only be done in conjunction with appropriately qualified nutrition professionals and be continually refined and optimized. Although endurance-trained athletes have an enhanced capacity for fat oxidation compared with untrained, this adaptation is clearly not maximized from training alone as it can be doubled, or even tripled, by chronic adaptation to a LCHF diet Burke et al.

However, studies have shown that as little as 5 days of exposure to HFLC diets, while continuing to undertake both high volume and intensity of training, achieves a robust retooling of the muscle to increase intramuscular triglycerides stores, and enhance the mobilization, transport, uptake, and oxidation of fats for review see Burke, By itself, however, chronic adaptation to a NK-LCHF does not translate into clear improvements in endurance performance, except in specific scenarios or individuals Burke, Therefore, a microperiodization protocol which theoretically could sequentially enhance the capacity of both fat- and CHO-based fuel oxidation prior to an endurance event has been proposed; this involves a 5—6 days fat adaptation phase followed by acute restoration of CHO availability just prior to and during the endurance task Burke et al.

Investigation of this protocol showed that the muscle retooling achieved by the fat-adaptation phase is robust in continuing to promote higher rates of fat oxidation in the face of aggressive strategies to restore high CHO availability during the endurance task Burke et al. Despite substantially reduced rates of muscle glycogen utilization during the early part of the exercise task, there was no clear enhancement of a subsequent time trial in any of these studies.

One apparent explanation for this outcome is that, rather than sparing glycogen utilization, chronic exposure to a high-fat diet causes an impairment of CHO oxidation during exercise due to a reduction on glycogenolysis and a downregulation of the activity of the pyruvate dehydrogenase complex [PDH; Stellingwerff et al.

Data from rodent models suggests that such inhibition of PDH activity may actually be due to the effects of reduced muscle glycogen availability.

Indeed, commencing exercise with reduced muscle glycogen augments the activation of peroxisome proliferator-activated receptor-δ PPAR-δ; Philp et al. In human muscle, however, we have recently shown that the downregulation of CHO metabolism appears to be a consequence of the high-fat diet and increased fat availability rather than CHO restriction alone Leckey et al.

The consequences of reduced CHO utilization within the tricarboxylic acid cycle are likely to manifest in a reduced capacity for ATP production at high intensities. The proposed benefits of chronic adaptation to ketogenic LCHF diets has also received recent attention in both the lay Brukner, and the scientific press Noakes et al.

However, Phinney et al. already noted that this feat was achieved in the face of impairments of capacity to undertake exercise at higher intensities. A more recent investigation of 3. In this study, some of the highest rates for fat oxidation ever reported in the literature were achieved following adaptation to the K-LCHF diet, under conditions of either fasting or intake of fat during a prolonged exercise protocol.

However, this was associated with an increase in the oxygen cost i. Taken together, chronic LCHF interventions have been shown to a decrease CHO oxidation Burke et al. This would decrease the effectiveness of CHO feeding strategies, thus increasing the risk of gut disturbances Jeukendrup, b.

It is important that coaches and athletes understand the metabolic demands and limiting factors in their events Figure 1and trial-specific interventions on an individual level Figure 3and realize that all sustained majority of track and field events are exceptionally CHO dependent.

The numerous various events in athletics, all with unique bioenergetics, biomechanical, and structural performance determinants, lend themselves to endless permutations of potential periodized nutrition interventions. Therefore, this review took a holistic approach to develop a nutrition periodization framework to guide practitioners in the field across these nutrition periodization options, while grounding them in targeted intervention first principles Figure 1 and Table 1.

From this framework, the literature has been examined regarding macro- meso- and microperiodization of CHO availability, and consequently, fat periodization Table 2 and Figure 2with considerations and recommendations to individualize and test in the field, as required Figure 3. However, Figure 1 highlights various other nutrition examples of periodization that are beyond the scope of this review, but we would highlight a few other papers in this series that also feature periodized nutrition examples for protein Witard et al.

Nutrient Periodization	While every sport is different, almost all require the duration, intensity, volume and load of training to change at different points in the season. Your diet should take a similar approach to your fitness plan. Eating the exact same thing day in and day out can not only lead to boredom, but it also prevents you from providing optimal fuel for your body. To get the most out of your diet, you should be using a technique known as nutrition periodization. Nutrition periodization refers to an eating plan that adjusts your food and fluid intake as your sports training changes. For example, the way you eat when you are doing two-a-day workouts in the pre-season will be different than when you are doing more weight training and less conditioning in the off-season. By creating a nutrition plan that complements your exercise routine, your body will be better able to recover from workouts, and you will feel ready to tackle your next workout. Nutrition periodization is set up in phases based on your training and competition schedule. The preparation phase is how you will eat during the pre-season. The competition phase is how you will eat and drink during the stage when you are actively competing, and the transition phase is how you will adjust your eating plan once the competitive phase is over and before the next season starts. During your pre-season training, you are in the preparation phase of eating. You should have two main goals during this phase. The first is to make sure you are eating enough to maintain your weight. That means focusing on your total daily intake and getting a nutritious breakfast, lunch, dinner and snacks. The second is to get into a good routine of eating and hydrating properly before, during, and after your workouts. This phase is a great time to experiment with sports drinks or other products that you may want to use during your workouts. Before or during exercise you may need to have some simple carbohydrates that are quickly absorbed. A carbohydrate-rich granola bar or fruit bar is another good example. Remember, what works for a teammate or a friend may not always work for you. By the end of this phase, you should know exactly what foods and fluids agree with you and provide sufficient energy for your competitions. If you ate and drank right through the preparation phase, you should feel highly confident with what you will eat and drink to fuel your competitions and events. During the competition phase, you will continue to eat and drink the same way you have practiced during the pre-season. Recovery nutrition becomes even more important, especially if you have back-to-back competitions or you are competing multiple days in a row. Make sure to get a snack or meal that contains both carbohydrates and some protein. Chocolate milk or a fruit and yogurt smoothie are both tasty and satisfying options that contain the nutrients needed to support recovery nutrition. Just like pre-season, you should eat and drink enough to maintain your body weight and support growth and development. The rest or off-season is referred to as the transition phase. During this period, both your exercise and eating may change quite a bit. You will still need to eat your regularly balanced meals and snacks, but the extra foods and fluids you were consuming to support training can be cut back. If you have a goal related to changing your body composition, this is the time to modify your diet to reach those goals. Continue to focus on your hydration plan and drink water to support your exercise. Overall, your diet should include foods that provide a lot of beneficial nutrients like protein, fiber, vitamins and minerals. Consider using some of your free time to cook a new recipe or take a trip to the grocery store to find a few new foods to try. No matter what phase you are in, eating a balanced diet that includes a variety of foods from each food group is key. You will need carbohydrate-rich foods to provide the energy needed to support your intense workouts. Choose a variety of complex carbohydrates like breads, pasta, and rice, as well as fruits and vegetables to provide your body with vitamins and minerals. We see that in competition season the carbohydrate intake increases due to the higher energy demands placed on the body. Protein remains moderate and there is slightly higher fat intake, also to help support the increased energy demands. We can also think about periodization on a daily basis. Regardless of which cycle you are in, the energy demands on your recovery day will be lower than on a high volume or high intensity day. Periodize your daily eating for optimal fueling habits. This takes the periodization down to the level of hours and minutes. In a recent review publication by Asker Jeukendrup Ref. This review includes nutrition training concepts, such as training on low glycogen stores , training on high muscle and liver glycogen , or training the gut to tolerate higher carbohydrate intake. Getting your nutrition right is an important component of optimal performance.

The purpose behind Periodiized Collagen support for skin and joints process of nutrition periodization entails strategic planning and adjusting certain variables to optimize results. Bbodybuilders so now that we know what nutrition periodization is and what Youth sports performance main dieting bodybuilder are, how do we apply that to our goals and where do you begin with tackling those goals? Your why will be what you lean on when things get tough. For example: If you want to lose weight so you can be a better version of yourself and live a longer, healthier lifestyle for yourself, kids, grandkids, etc. NOT the fact that you want to look good naked.
