A primary goal of traditional post-workout fpr timing recommendations energh to replenish glycogen stores. MacDougall et al. Similarly, Robergs et toming. It therefore stands to reason that typical high eenergy bodybuilding-style workouts Nutrienh multiple exercises and sets Proper hydration for older sports performers the same muscle group would deplete the majority of local glycogen stores.

Nuhrient addition, there Nutrient timing for energy timinv that glycogen serves to mediate intracellular signaling. Talent identification and selection appears to be due, at least in part, to its negative regulatory effects on AMP-activated protein kinase AMPK.

Muscle Nuutrient and catabolism are regulated by a Nutruent cascade of signaling pathways. AMPK, on the Carbohydrates in Sports Nutrition hand, timin a cellular Electrolyte Benefits sensor that serves to enhance energy availability.

As such, it blunts energy-consuming processes including the activation of mTORC1 mediated by insulin and mechanical ehergy, as well as heightening catabolic processes such Nutrien glycolysis, beta-oxidation, and protein Nitrient [ 9 ].

mTOR is considered a master network enerhy the regulation of skeletal muscle growth [ 1011 ], and its Memory enhancement techniques has a decidedly negative effect on energgy processes [ 12 ].

Glycogen has been fo to inhibit purified Yiming in cell-free Revolutionary Fat Burner [ 13 ], and low glycogen levels are associated with an enhanced AMPK activity in humans in vivo [ 14 ]. Creer et al. Glycogen inhibition also has been shown to blunt S6K activation, impair translation, and reduce the amount of mRNA of genes responsible for regulating muscle hypertrophy [ 16Nutroent ].

In contrast to these findings, a recent study by Camera et al. The discrepancy between studies is not clear at this time. Glycogen availability also has been shown to mediate muscle protein breakdown.

Lemon and Mullin [ 19 ] found that nitrogen losses more than doubled following a bout of exercise in a glycogen-depleted versus glycogen-loaded state. Other researchers have displayed a similar inverse relationship between glycogen levels and proteolysis [ 20 ].

Considering the totality of evidence, maintaining a high intramuscular glycogen content at the onset of training appears tmiing to desired resistance training outcomes. Exercise enhances insulin-stimulated glucose uptake following a workout with a strong correlation noted between the amount of uptake and the magnitude of glycogen utilization [ 22 ].

This is in part due to an increase in the translocation of GLUT4 during glycogen depletion [ 2324 ] thereby facilitating entry of glucose into the cell. Tor addition, there is an exercise-induced increase in the activity of glycogen synthase—the principle enzyme involved in promoting glycogen storage [ 25 ].

The combination of these factors facilitates the rapid uptake of glucose following an exercise bout, allowing glycogen to be replenished at an accelerated rate. There is evidence that adding protein to a post-workout carbohydrate meal can enhance glycogen re-synthesis. Berardi et al.

Similarly, Ivy et al. The synergistic effects of protein-carbohydrate have been attributed to a more pronounced insulin response [ 28 timingg, although it should be noted that not all studies support these findings [ 29 ]. Jentjens et al. Despite a sound theoretical basis, the practical significance of expeditiously repleting glycogen stores remains dubious.

Without question, expediting energ resynthesis is important for a narrow subset of endurance sports enedgy the duration between glycogen-depleting events is limited to less than approximately 8 hours [ 31 ]. Similar benefits could potentially be obtained by those who perform two-a-day split resistance training bouts i.

morning and evening provided the same muscles will be worked during the respective sessions. However, timung goals that are not specifically focused on the performance of multiple exercise bouts in the same day, Nutient urgency of glycogen resynthesis is greatly diminished. Certain athletes are prone to performing significantly more volume than this i.

For example, training Nuttient muscle group with sets in a single session is done roughly once per week, whereas routines with sets are done twice per week.

In scenarios of higher volume and frequency of resistance training, incomplete resynthesis of pre-training glycogen levels would not be a concern aside from enerby far-fetched scenario where exhaustive training bouts of the same muscles occur after recovery intervals shorter than 24 hours.

However, even in the event of complete glycogen depletion, replenishment to pre-training levels occurs well-within this timeframe, regardless of a significantly delayed post-exercise carbohydrate intake. For example, Parkin et al [ 33 ] compared the immediate post-exercise ingestion of 5 high-glycemic carbohydrate meals with a 2-hour wait before beginning the recovery feedings.

No timiing between-group differences were seen in glycogen levels at 8 hours and 24 hours post-exercise. In further support of this point, Fox et al.

Another purported benefit of post-workout nutrient timing is an attenuation of muscle protein breakdown. This is primarily achieved by spiking insulin levels, as opposed to increasing amino acid availability [ 3536 ].

Studies show that muscle protein breakdown is only slightly elevated immediately post-exercise toming then rapidly rises thereafter [ 36 ]. In the fasted state, muscle protein breakdown is significantly heightened at minutes following resistance exercise, resulting in a net negative protein balance [ 37 ].

Although insulin has known anabolic properties [ 3839 ], its primary impact post-exercise is believed to be anti-catabolic [ 40 — 43 ]. The mechanisms by which insulin reduces proteolysis are not well understood at this time.

Down-regulation of other aspects of the ubiquitin-proteasome pathway are also believed to play a role in the process [ 45 ]. Given that muscle hypertrophy represents the difference between myofibrillar protein synthesis and proteolysis, a decrease in protein breakdown would conceivably enhance accretion of contractile proteins and thus facilitate greater hypertrophy.

Accordingly, it seems logical to conclude that consuming a protein-carbohydrate supplement following exercise would promote the greatest reduction in proteolysis since the combination of the two nutrients has been shown to elevate insulin levels to a greater extent than carbohydrate alone [ 28 ].

However, while the theoretical basis behind spiking insulin post-workout is inherently sound, it remains questionable as to whether benefits extend into practice. This insulinogenic effect is easily accomplished with typical mixed meals, considering Nutient it takes approximately 1—2 hours for circulating substrate levels to peak, and 3—6 hours or more for a complete return to basal levels depending on the size of a meal.

For example, Capaldo et al. This meal was able to raise insulin 3 times above fasting levels within 30 minutes of consumption. At the 1-hour mark, insulin was 5 times greater than fasting. At the 5-hour mark, insulin was still double the fasting levels. In another example, Power et al.

The inclusion of carbohydrate to this protein dose would cause insulin levels to peak higher and stay elevated even longer. Therefore, the recommendation for lifters to spike insulin post-exercise fo somewhat trivial. The classical post-exercise objective to quickly reverse catabolic processes to promote recovery and growth may only be applicable in the absence of a properly constructed pre-exercise meal.

Moreover, there is evidence that the effect of protein breakdown on muscle protein accretion may be overstated. Glynn et al. These results were seen regardless of the extent of circulating Nitrient levels.

Thus, it remains questionable as to what, if any, positive effects are realized timng respect to muscle growth from spiking insulin after resistance training.

Perhaps the most touted benefit of post-workout nutrient timing is that it timinf increases in MPS. Resistance training alone has been shown to promote a twofold increase in protein synthesis following exercise, which is counterbalanced by the accelerated rate of proteolysis [ 36 ].

It appears that the stimulatory effects of hyperaminoacidemia on muscle protein synthesis, especially from essential amino acids, are potentiated by previous exercise [ 3550 ]. There is some evidence that carbohydrate has an timign effect on enhancing post-exercise muscle protein synthesis Nutdient combined with amino acid ingestion [ 51 ], but others have fpr to find such a benefit [ 5253 ].

However, despite the common recommendation to consume protein as soon as possible post-exercise [ 6061 ], evidence-based support for this practice is currently lacking. Levenhagen fiming al. Employing a within-subject design,10 volunteers 5 men, 5 women consumed an oral supplement containing 10 g protein, 8 g carbohydrate and 3 g fat either immediately following or three hours post-exercise.

A limitation of the study was that training involved moderate intensity, long duration aerobic exercise. In contrast to the timing effects shown by Levenhagen Nufrient al.

Enedgy, Fujita et al [ 64 ] saw opposite results using a similar design, except the Timinh was ingested 1 hour prior to exercise compared to ingestion immediately pre-exercise in Tipton et ejergy. Adding yet more incongruity to the evidence, Tipton et al. Collectively, the available data lack any consistent indication of an ideal post-exercise timing scheme for maximizing MPS.

It also Nturient be noted that measures of MPS assessed following an acute bout of resistance exercise do not always occur in parallel with chronic upregulation of causative energj signals [ 66 ] and are not necessarily predictive of long-term hypertrophic responses to regimented resistance training [ 67 ].

Moreover, the post-exercise rise in MPS in untrained subjects is not recapitulated in the trained state [ 68 ], further confounding practical relevance. Thus, the utility of acute studies is limited to providing clues and generating hypotheses regarding hypertrophic adaptations; any attempt to extrapolate findings from such data to changes in lean body mass is speculative, at best.

Energg number of studies have directly investigated the long-term hypertrophic effects of post-exercise protein consumption. The results of these trials are curiously conflicting, seemingly because of varied tuming design and methodology.

Introduction Nutrient timing: during exercise Much like the consideration of pre-exercise nutrient supplementation, a majority of the literature which has examined the impact of nutrient administration during exercise has focused on aerobic exercise [ 33 — 36 ], with a lesser emphasis on nutrient administration during resistance exercise [ 37 — 41 ]. The authors concluded that pre-exercise ingestion of CHO improves performance only when CHO ingestion is maintained throughout exercise, and ingestion of CHO during min of cycling improves subsequent time trial performance [ 33 ]. These sports supplements are formulated with a specific composition of nutrients to rapidly supply carbohydrates and electrolytes. Regular foods are ideal e. PubMed Google Scholar. Thus, you can restore glycogen more quickly and prepare for your next workout, when you consume a combination of carbohydrate and protein and for the record, a few grams of fat does not delay absorption significantly. Another way to monitor hydration is by checking urine color.

Supplement manufacturers lead you to believe that liquid calories are superior to solid foods because they are absorbed more rapidly. And in a laboratory setting, this may be the case.

But the only reason to use a supplement over a food is convenience. Few of us have live-in chefs and all of us have busy schedules, so quite often carrying a bar or shaker bottle are the only viable options.

When you do have the opportunity to prepare a meal, the extra digestion time compared to a shake will not hinder glycogen or protein resynthesis.

In fact lean meats, fruits, vegetables and whole grains have the benefit of more vitamins, minerals and antioxidants than the contents of your shaker bottle and may be considerably less expensive.

Transportable food options such as chocolate milk, fruit, yogurt, trail mix, homemade energy bars and sandwiches may provide the best of both worlds.

As whole foods, they are nutrient dense and unprocessed, yet easy to take to the office or gym. High-water foods such as melons, apples, pears, cucumbers and bell peppers provide the benefit of assisting with re-hydration as well but you still need to drink water before, during, and after exercise.

A quick note regarding chocolate milk, which some tout as the best post-workout option. Low-fat chocolate milk has a great ratio of macronutrients, provides vitamins and minerals and is incredibly cost-effective. However, most of the research involving chocolate milk is flawed as it has been compared to lower-calorie drinks and it is no more or less effective than a similar drink or food providing the same amount of calories, carbohydrates and protein.

Your goals are an incredibly important consideration when making pre-, during, and post-workout food choices. Two different people, for example—one with weight-loss aspirations, one with healthy weight gain ambitions—should have two different fueling plans. For a weight-loss plan, total calories and carbohydrate should be less compared to a hypertrophy plan; protein, however, should remain relatively constant see below for more details.

No one lives in a laboratory and almost no one measures every ounce of food or calculates carbohydrates and proteins down to the tenth of a gram. For a pound individual with the goal of maintaining or gaining weight , these recommendations boil down to 90 grams of carbohydrate and 30 grams of protein a carbohydrate-to-protein ratio.

What You Need to Know About Nutrient Timing. by Justin Robinson on February 08, Filter By Category. View All Categories. View All Lauren Shroyer Jason R.

Karp, Ph. Wendy Sweet, Ph. There are several benefits of nutrient timing. These involve maximizing your body's response to exercise and use of nutrients.

The Nutrient Timing Principles NTP help you do the following:. When sports nutritionists talk about energy, we are referring to the potential energy food contains.

Calories are potential energy to be used by muscles, tissues, and organs to fuel the task at hand. Much of the food we eat is not burned immediately for energy the minute it's consumed. Rather, our bodies digest, absorb, and prepare it so that it can give us the kind of energy we need, when we need it.

We transform this potential energy differently for different tasks. How we convert potential energy into usable energy is based on what needs to get done and how well prepared our bodies are; how we fuel endurance work is different from how we fuel a short, intense run. It is helpful to understand that you must get the food off your plate and into the right places in your body at the right time.

If you're talking about vitality, liveliness, get-up-and-go, then a number of things effect this: amount of sleep, hydration, medical conditions, medications, attitude, type of foods eaten, conditioning and appropriate rest days, and timing of meals and snacks.

Food will help a lack of energy only if the problem is food related. You may think that's obvious, but it's not to some. If you're tired because you haven't slept enough, for instance, eating isn't going to give you energy.

What, how much, and when you eat will affect your energy. Nutrient timing combined with appropriate training maximizes the availability of the energy source you need to get the job done, helps ensure that you have fuel ready and available when you need it, and improves your energy-burning systems.

You may believe that just eating when you are hungry is enough, and in some cases this may be true. But, many times, demands on time interfere with fueling or refueling, and it takes conscious thought and action to make it happen. Additionally, appetites are thrown off by training, so you may not be hungry right after practice, but by not eating, you are starving while sitting at your desk in class or at work.

Many athletes just don't know when and what to eat to optimize their energy stores. By creating and following your own Nutrition Blueprint and incorporating the NTP, your energy and hunger will be more manageable and consistent, whether you are training several times a week, daily, participating in two-a-days, or are in the midst of the competitive season.

During the minutes and hours after exercise, your muscles are recovering from the work you just performed. The energy used and damage that occurred during exercise needs to be restored and repaired so that you are able to function at a high level at your next workout.

Some of this damage is actually necessary to signal repair and growth, and it is this repair and growth that results in gained strength. However, some of the damage is purely negative and needs to be minimized or it will eventually impair health and performance.

Providing the right nutrients, in the right amounts, at the right time can minimize this damage and restore energy in time for the next training session or competition. The enzymes and hormones that help move nutrients into your muscles are most active right after exercise.

Key post-exercise considerations include:. For athletes training intensely or multiple times a day, a small bedtime snack that includes protein can support muscle repair during sleep. It's important to note that nutrient timing is not a one-size-fits-all approach. Individual factors such as the type of sport, training intensity, body composition goals, and personal preferences influence nutrient timing strategies.

Athletes should customize their nutrient timing plan based on their unique needs and goals. For athletes with specific dietary needs, performance goals, or complex training schedules, consulting a registered dietitian or sports nutritionist is highly beneficial.

They can provide personalized guidance and meal plans tailored to your training regimen and objectives. Nutrient timing is a science that can significantly impact an athlete's performance, recovery, and overall training outcomes. By strategically planning when and what to eat before, during, and after exercise, athletes can maximize their energy levels, enhance performance, and accelerate recovery.

Remember that nutrient timing should be individualized to align with your unique training and performance goals. Timing is indeed everything when it comes to achieving peak athletic performance. Share Share Link.

The Science Behind Nutrient Timing The concept of nutrient timing revolves around the idea that the body's nutritional needs vary depending on the time of day and the type of physical activity. Proper nutrient timing aims to: Maximize Energy Levels: Fueling before exercise ensures that the body has enough energy to perform optimally.

Enhance Performance: Consuming the right nutrients during exercise can sustain endurance and intensity. Accelerate Recovery: Post-exercise nutrition aids muscle repair, glycogen replenishment, and overall recovery.

Article Pag e. Nutrient Timing: The New Frontier in Fitness Performance Ashley Chambers, M. and Len Kravitz, Ph. Introduction Exercise enthusiasts in aquatic exercise and other modes of exercise regularly seek to improve their strength, stamina, muscle power and body composition through consistent exercise and proper nutrition.

It has shown that proper nutritional intake and a regular exercise regimen will bolster the body in achieving optimal physiological function Volek et al. The science behind nutrient timing suggests that knowing what to eat and when to eat is a critical key to successfully achieving these health, fitness and performance goals.

This article will synthesize the current understanding of how nutrient timing helps to repair tissue damage, restore physiological function, replenish glycogen stores, and promote muscle growth. What Is Nutrient Timing? Nutrient timing is the application of knowing when to eat and what to eat before, during and after exercise.

It is designed to help athletes, recreational competitors, and exercise enthusiasts achieve their most advantageous exercise performance and recovery.

There are three distinct phases in the nutrient timing system that are based on muscle, its nutritional requirements, and its recovery demands for best strength and endurance results.

But first, a basic review of the hormones of exercise is warranted. The Hormonal Responses To Exercise Within the body are numerous catabolic breaking down and anabolic building up hormones that are stimulated by exercise. Catabolic hormones aid in the disassembly of nutrients for energy production or cells needs.

The main catabolic hormones of exercise are epinephrine, norepinephrine, cortisol and glucagon. Anabolic hormones support muscle hypertrophy growth , tissue repair, inflammation control, and facilitate the regulation of carbohydrate, fat and protein metabolism.

The anabolic hormones of interest during exercise are insulin, testosterone, IGF-I and growth hormone. The Catabolic Hormones During aerobic exercise, levels of epinephrine and norepinephrine are elevated to prepare or mobilize the cells for the breakdown of glycogen converting it to glucose for fuel in the liver and muscle.

These hormones also increase the heart rate, blood pressure, heart contractility, blood redistribution to muscle, and respiration rate to meet the physiological needs of the continuous dynamic exercise. Cortisol is largely responsible for the breakdown of carbohydrate and fat for energy during exercise.

It is a very important catabolic hormone that is activated when low blood glucose levels are present, such as during exhaustive exercise. If the body is low in glucose and glycogen, cortisol will send amino acids to the liver to make new glucose, referred to as gluconeogeneses.

Thus, in exercise, when carbohydrate sources are dwindling, cortisol takes the building blocks of proteins amino acids and uses them for new glucose synthesis. The Anabolic Hormones One widely known anabolic hormone is insulin. Insulin sensitivity is increased during aerobic and resistance exercise, which literally means there is an enhanced glucose uptake for muscle contraction.

It also accelerates the transport of amino acids into muscle and stimulates protein synthesis in muscles Levenhagen et al. However, during sustained aerobic exercise insulin levels in the blood decrease slightly because epinephrine and norepinephrine inhibit the release of insulin from the pancreas.

Another important anabolic hormone is testosterone. Testosterone is a powerful hormone for protein synthesis and muscle hypertrophy. Growth hormone is an anabolic hormone that promotes bone and cartilage growth. It is also responsible for stimulating IGF-I, a hormone responsible for the development of muscle cells from myoblasts immature muscle cells into myotubes growing muscles cells and then into mature muscle fibers.

High levels of IGF-I are needed in order to promote muscle hypertrophy. Read more: What to Eat Before a Workout. Timing is a huge consideration for preworkout nutrition. Too early and the meal is gone by the time the exercise begins; too late and the stomach is uncomfortably sloshing food around during the activity.

Although body size, age, gender, metabolic rate, gastric motility and type of training are all meal-timing factors to consider, the ideal time for most people to eat is about hours before activity. If lead times are much shorter a pre-7 a.

workout, for example , eating a smaller meal of less than calories about an hour before the workout can suffice. For a pound athlete, that would equate to about 68 g or servings of carbohydrate, 1 hour before exercise. For reference, 1 serving of a carbohydrate food contains about 15 g of carbohydrate.

There are about 15 g of carbohydrate in each of the following: 1 slice of whole-grain bread, 1 orange, ½ cup cooked oatmeal, 1 small sweet potato or 1 cup low-fat milk. It is generally best that anything consumed less than 1 hour before an event or workout be blended or liquid-such as a sports drink or smoothie-to promote rapid stomach emptying.

Bear in mind that we are all individuals and our bodies will perform differently. It may take some study to understand what works best for you. Preworkout foods should not only be easily digestible, but also easily and conveniently consumed.

A comprehensive preworkout nutrition plan should be evaluated based on the duration and intensity of exertion, the ability to supplement during the activity, personal energy needs, environmental conditions and the start time. For instance, a person who has a higher weight and is running in a longer-distance race likely needs a larger meal and supplemental nutrition during the event to maintain desired intensity.

Determining how much is too much or too little can be frustrating, but self-experimentation is crucial for success. The athlete ought to sample different prework-out meals during various training intensities as trials for what works. Those training for a specific event should simulate race day as closely as possible time of day, conditions, etc.

when experimenting with several nutrition protocols to ensure optimal results. See how to count macros to keep your nutrient timing as effective as possible. Supplemental nutrition may not be necessary during shorter or less-intense activity bouts.

If so, carbohydrate consumption should begin shortly after the start of exercise. One popular sports-nutrition trend is to use multiple carb sources with different routes and rates of absorption to maximize the supply of energy to cells and lessen the risk of GI distress Burd et al. Consuming ounces of such drinks every minutes during exercise has been shown to extend the exercise capacity of some athletes ACSM However, athletes should refine these approaches according to their individual sweat rates, tolerances and exertion levels.

Some athletes prefer gels or chews to replace carbohydrates during extended activities. These sports supplements are formulated with a specific composition of nutrients to rapidly supply carbohydrates and electrolytes.

Most provide about 25 g of carbohydrate per serving and should be consumed with water to speed digestion and prevent cramping. To improve fitness and endurance, we must anticipate the next episode of activity as soon as one exercise session ends.

That means focusing on recovery, one of the most important-and often overlooked-aspects of proper sports nutrition. An effective nutrition recovery plan supplies the right nutrients at the right time. Recovery is the body's process of adapting to the previous workload and strengthening itself for the next physical challenge.

Nutritional components of recovery include carbohydrates to replenish depleted fuel stores, protein to help repair damaged muscle and develop new muscle tissue, and fluids and electrolytes to rehydrate. A full, rapid recovery supplies more energy and hydration for the next workout or event, which improves performance and reduces the chance of injury.

Training generally depletes muscle glycogen. To maximize muscle glycogen replacement, athletes should consume a carbohydrate-rich snack within this minute window. The recommendation for rapidly replenishing glycogen stores is to take in foods providing 1.

For a pound athlete, that equates to between 68 and g of carbs or ~ 4. Since this can be difficult to consume in whole foods shortly after activity, liquid and bar supplements may be useful and convenient after exercise.

Consuming smaller amounts of carbohydrates more frequently may be prudent if the previous recommendation leaves the athlete feeling too full.

Bananas are a great source of healthy carbs , if you didn't know! Muscle tissue repair and muscle building are important for recovery. Whether you're focusing on endurance or strength training, taking in protein after a workout provides the amino acid building blocks needed to repair muscle fibers that get damaged and catabolized during exercise, and to promote the development of new muscle tissue.

Recent research has further demonstrated that a similar amount of protein approximately g after resistance exercise may even benefit athletes on calorie-restricted diets who also want to maintain lean body mass Areta et al.

It is important to note that some literature emphasizing extremely high levels of protein intake-well beyond these recommendations-for strength training may be dated and lack quality research Spendlove et al.

Virtually all weight lost during exercise is fluid, so weighing yourself without clothes before and after exercise can help gauge net fluid losses. It is important to restore hydration status before the next exercise period.

However, water may be all you need if exercising for less than 1 hour at a low intensity. While these recommendations are a good starting point, there are no absolute sports nutrition rules that satisfy everyone's needs…so paying attention to how you feel during exercise and how diet affects performance is of utmost importance.

You may have to use different timing and alternate routines to create a nutrition and exercise combo that works best.

Timing certainly is critical in sports nutrition, and optimizing that can make all the difference! Read also: Muscle Clocks - The Value of Synchronized Training. Fast fix: You can positively affect event outcomes by eating the right foods in the right amounts at the right times.

A good way to start recovery is to consume a snack with carbohydrates and a moderate amount of protein, plus fluids and sodium, within 30 minutes after exercise.

Pre-Exercise Nutrition: Nutrition before exercise is essential to provide the body with the energy it needs to perform at its best. Key considerations include: Carbohydrates: Consume complex carbohydrates hours before exercise to top off glycogen stores and provide sustained energy.

Protein: Include a small amount of protein to support muscle repair and reduce muscle damage. Hydration: Begin exercise well-hydrated by drinking fluids leading up to your workout.

During Exercise Nutrition: For prolonged or high-intensity exercise, maintaining energy levels is critical. During exercise, focus on: Carbohydrates: Consume easily digestible carbohydrates in the form of gels, chews, or sports drinks to sustain energy levels.

Hydration: Regularly drink fluids to prevent dehydration, especially in hot or humid conditions. Post-Exercise Nutrition: The post-exercise recovery window is a crucial period for muscle repair and glycogen replenishment.

Key post-exercise considerations include: Carbohydrates: Consume carbohydrates immediately after exercise to replenish glycogen stores. Protein: Include a source of protein to support muscle repair and growth. Fluids and Electrolytes: Rehydrate with fluids containing electrolytes to replace what was lost through sweat.

Bedtime Snack: For athletes training intensely or multiple times a day, a small bedtime snack that includes protein can support muscle repair during sleep.
