Nutrient Timing

Maximize nutrient timing -

This timing also impacts the ability to gain strength and for the body to adapt to exercise. The strategy you use when timing nutrition will vary based on your desired goal. Protein is key to helping muscle grow. It is also critical for boosting muscle strength.

Consuming protein during the anabolic phase can help muscle repair after resistance exercise. It can even help reduce muscle protein breakdown the next morning according to one study.

Consuming 20 grams of protein after exercise helps support muscle protein synthesis. While it may be tempting to aim for more, one study found that this provides no additional benefit. Protein needs vary based on level of physical activity.

An athlete engaged in moderate-intensity exercise needs 0. An athlete engaging in more intense exercise needs more, or between 1. Those engaging in resistance exercise also need this higher amount.

What does nutrient timing look like if the goal is weight loss? Much of the research in this area involves eating habits, in general, as opposed to eating before, during, or after exercise.

One study that addresses this topic focuses on endurance athletes. It notes that fat loss can be achieved for this type of athlete by:. The path to fat loss without losing muscle changes depends on exercise intensity. If the intensity is high, increased carbohydrate consumption can help meet this demand.

If the workout is low intensity, focus more on protein. Performance nutrition is gaining in popularity. Some suggest that access to a sports dietitian can improve performance for pro athletes. This is the basis of an April article published in the Journal of the International Society of Sports Nutrition.

The strategy for nutrition timing varies based on the sport. If the athlete runs marathons, fueling up a few hours before the run provides energy for the event. Carbohydrate foods are best.

A good calorie count is calories or less. After the race, refuel with a light meal. If the sport relies on muscle strength, refuel with protein within a few hours. This helps the body as it repairs muscle damage. Approximately 20 grams is a good place to start.

More may be needed if the sport is intense. A carbohydrate rich meal a few hours before aerobic exercise helps provide the energy needed. Adding a little protein can help keep the energy going. Have a banana carbohydrate with some peanut butter protein. Or eat a couple of wheat crackers carbohydrate with cubes of cheese protein.

When lifting weights, post exercise protein is important. This will help the muscle tissue recover. It also aids in skeletal muscle growth.

Aim to consume this protein within a few hours. A protein shake is an easy option. Scrambling some eggs or having a salad with chicken are more options.

An endurance athlete needs enough energy to sustain movement long-term. This involves fueling the body with a high carbohydrate meal a few hours before the training.

If the training session is long, a carbohydrate snack may be needed during the workout. Afterward, have a light meal that includes both protein and carbs. Sports nutrition is an ever-changing field.

And every person is different. What works for one client or athlete may not work for another. Some may benefit from carbohydrate ingestion before exercise while others gain the most advantage by exercising in a fasted state. Working with a sports nutrition specialist can provide clients individualized guidance.

It takes into account their training program. It also considers how their body responds to protein and carbs. Levenhagen et 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 et al. Notably, Fujita et al [ 64 ] saw opposite results using a similar design, except the EAA-carbohydrate was ingested 1 hour prior to exercise compared to ingestion immediately pre-exercise in Tipton et al.

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 should 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 myogenic 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.

A 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 study design and methodology.

Moreover, a majority of studies employed both pre- and post-workout supplementation, making it impossible to tease out the impact of consuming nutrients after exercise. Esmarck et al. Thirteen untrained elderly male volunteers were matched in pairs based on body composition and daily protein intake and divided into two groups: P0 or P2.

Subjects performed a progressive resistance training program of multiple sets for the upper and lower body. Training was carried out 3 days a week for 12 weeks. At the end of the study period, cross-sectional area CSA of the quadriceps femoris and mean fiber area were significantly increased in the P0 group while no significant increase was seen in P2.

These results support the presence of a post-exercise window and suggest that delaying post-workout nutrient intake may impede muscular gains. In contrast to these findings, Verdijk et al. Twenty-eight untrained subjects were randomly assigned to receive either a protein or placebo supplement consumed immediately before and immediately following the exercise session.

Subjects performed multiple sets of leg press and knee extension 3 days per week, with the intensity of exercise progressively increased over the course of the 12 week training period.

No significant differences in muscle strength or hypertrophy were noted between groups at the end of the study period indicating that post exercise nutrient timing strategies do not enhance training-related adaptation. It should be noted that, as opposed to the study by Esmark et al.

In an elegant single-blinded design, Cribb and Hayes [ 70 ] found a significant benefit to post-exercise protein consumption in 23 recreational male bodybuilders.

Subjects were randomly divided into either a PRE-POST group that consumed a supplement containing protein, carbohydrate and creatine immediately before and after training or a MOR-EVE group that consumed the same supplement in the morning and evening at least 5 hours outside the workout.

Results showed that the PRE-POST group achieved a significantly greater increase in lean body mass and increased type II fiber area compared to MOR-EVE. Findings support the benefits of nutrient timing on training-induced muscular adaptations.

The study was limited by the addition of creatine monohydrate to the supplement, which may have facilitated increased uptake following training. Moreover, the fact that the supplement was taken both pre- and post-workout confounds whether an anabolic window mediated results.

Willoughby et al. Nineteen untrained male subjects were randomly assigned to either receive 20 g of protein or 20 grams dextrose administered 1 hour before and after resistance exercise.

Training was performed 4 times a week over the course of 10 weeks. At the end of the study period, total body mass, fat-free mass, and thigh mass was significantly greater in the protein-supplemented group compared to the group that received dextrose.

Given that the group receiving the protein supplement consumed an additional 40 grams of protein on training days, it is difficult to discern whether results were due to the increased protein intake or the timing of the supplement.

In a comprehensive study of well-trained subjects, Hoffman et al. Seven participants served as unsupplemented controls. Workouts consisted of 3—4 sets of 6—10 repetitions of multiple exercises for the entire body.

Training was carried out on 4 day-a-week split routine with intensity progressively increased over the course of the study period. After 10 weeks, no significant differences were noted between groups with respect to body mass and lean body mass. The study was limited by its use of DXA to assess body composition, which lacks the sensitivity to detect small changes in muscle mass compared to other imaging modalities such as MRI and CT [ 76 ].

Hulmi et al. High-intensity resistance training was carried out over 21 weeks. Supplementation was provided before and after exercise.

At the end of the study period, muscle CSA was significantly greater in the protein-supplemented group compared to placebo or control. A strength of the study was its long-term training period, providing support for the beneficial effects of nutrient timing on chronic hypertrophic gains. Again, however, it is unclear whether enhanced results associated with protein supplementation were due to timing or increased protein consumption.

Most recently, Erskine et al. Subjects were 33 untrained young males, pair-matched for habitual protein intake and strength response to a 3-week pre-study resistance training program. After a 6-week washout period where no training was performed, subjects were then randomly assigned to receive either a protein supplement or a placebo immediately before and after resistance exercise.

Training consisted of 6— 8 sets of elbow flexion carried out 3 days a week for 12 weeks. No significant differences were found in muscle volume or anatomical cross-sectional area between groups. The hypothesis is based largely on the pre-supposition that training is carried out in a fasted state.

During fasted exercise, a concomitant increase in muscle protein breakdown causes the pre-exercise net negative amino acid balance to persist in the post-exercise period despite training-induced increases in muscle protein synthesis [ 36 ].

Thus, in the case of resistance training after an overnight fast, it would make sense to provide immediate nutritional intervention--ideally in the form of a combination of protein and carbohydrate--for the purposes of promoting muscle protein synthesis and reducing proteolysis, thereby switching a net catabolic state into an anabolic one.

Over a chronic period, this tactic could conceivably lead cumulatively to an increased rate of gains in muscle mass. This inevitably begs the question of how pre-exercise nutrition might influence the urgency or effectiveness of post-exercise nutrition, since not everyone engages in fasted training.

Tipton et al. Although this finding was subsequently challenged by Fujita et al. These data indicate that even minimal-to-moderate pre-exercise EAA or high-quality protein taken immediately before resistance training is capable of sustaining amino acid delivery into the post-exercise period.

Given this scenario, immediate post-exercise protein dosing for the aim of mitigating catabolism seems redundant. The next scheduled protein-rich meal whether it occurs immediately or 1—2 hours post-exercise is likely sufficient for maximizing recovery and anabolism. On the other hand, there are others who might train before lunch or after work, where the previous meal was finished 4—6 hours prior to commencing exercise.

This lag in nutrient consumption can be considered significant enough to warrant post-exercise intervention if muscle retention or growth is the primary goal. Layman [ 77 ] estimated that the anabolic effect of a meal lasts hours based on the rate of postprandial amino acid metabolism.

However, infusion-based studies in rats [ 78 , 79 ] and humans [ 80 , 81 ] indicate that the postprandial rise in MPS from ingesting amino acids or a protein-rich meal is more transient, returning to baseline within 3 hours despite sustained elevations in amino acid availability.

In light of these findings, when training is initiated more than ~3—4 hours after the preceding meal, the classical recommendation to consume protein at least 25 g as soon as possible seems warranted in order to reverse the catabolic state, which in turn could expedite muscular recovery and growth.

However, as illustrated previously, minor pre-exercise nutritional interventions can be undertaken if a significant delay in the post-exercise meal is anticipated. An interesting area of speculation is the generalizability of these recommendations across training statuses and age groups.

Burd et al. This suggests a less global response in advanced trainees that potentially warrants closer attention to protein timing and type e. In addition to training status, age can influence training adaptations. The mechanisms underlying this phenomenon are not clear, but there is evidence that in younger adults, the acute anabolic response to protein feeding appears to plateau at a lower dose than in elderly subjects.

Illustrating this point, Moore et al. In contrast, Yang et al. These findings suggest that older subjects require higher individual protein doses for the purpose of optimizing the anabolic response to training. The body of research in this area has several limitations.

First, while there is an abundance of acute data, controlled, long-term trials that systematically compare the effects of various post-exercise timing schemes are lacking. The majority of chronic studies have examined pre- and post-exercise supplementation simultaneously, as opposed to comparing the two treatments against each other.

This prevents the possibility of isolating the effects of either treatment. That is, we cannot know whether pre- or post-exercise supplementation was the critical contributor to the outcomes or lack thereof. Another important limitation is that the majority of chronic studies neglect to match total protein intake between the conditions compared.

Further, dosing strategies employed in the preponderance of chronic nutrient timing studies have been overly conservative, providing only 10—20 g protein near the exercise bout. More research is needed using protein doses known to maximize acute anabolic response, which has been shown to be approximately 20—40 g, depending on age [ 84 , 85 ].

There is also a lack of chronic studies examining the co-ingestion of protein and carbohydrate near training. Thus far, chronic studies have yielded equivocal results. On the whole, they have not corroborated the consistency of positive outcomes seen in acute studies examining post-exercise nutrition.

Another limitation is that the majority of studies on the topic have been carried out in untrained individuals. Muscular adaptations in those without resistance training experience tend to be robust, and do not necessarily reflect gains experienced in trained subjects.

It therefore remains to be determined whether training status influences the hypertrophic response to post-exercise nutritional supplementation. A final limitation of the available research is that current methods used to assess muscle hypertrophy are widely disparate, and the accuracy of the measures obtained are inexact [ 68 ].

As such, it is questionable whether these tools are sensitive enough to detect small differences in muscular hypertrophy. Although minor variances in muscle mass would be of little relevance to the general population, they could be very meaningful for elite athletes and bodybuilders.

Thus, despite conflicting evidence, the potential benefits of post-exercise supplementation cannot be readily dismissed for those seeking to optimize a hypertrophic response.

Practical nutrient timing applications for the goal of muscle hypertrophy inevitably must be tempered with field observations and experience in order to bridge gaps in the scientific literature.

With that said, high-quality protein dosed at 0. For example, someone with 70 kg of LBM would consume roughly 28—35 g protein in both the pre- and post exercise meal. Exceeding this would be have minimal detriment if any, whereas significantly under-shooting or neglecting it altogether would not maximize the anabolic response.

Due to the transient anabolic impact of a protein-rich meal and its potential synergy with the trained state, pre- and post-exercise meals should not be separated by more than approximately 3—4 hours, given a typical resistance training bout lasting 45—90 minutes.

If protein is delivered within particularly large mixed-meals which are inherently more anticatabolic , a case can be made for lengthening the interval to 5—6 hours. This strategy covers the hypothetical timing benefits while allowing significant flexibility in the length of the feeding windows before and after training.

Specific timing within this general framework would vary depending on individual preference and tolerance, as well as exercise duration.

One of many possible examples involving a minute resistance training bout could have up to minute feeding windows on both sides of the bout, given central placement between the meals.

In contrast, bouts exceeding typical duration would default to shorter feeding windows if the 3—4 hour pre- to post-exercise meal interval is maintained. Even more so than with protein, carbohydrate dosage and timing relative to resistance training is a gray area lacking cohesive data to form concrete recommendations.

It is tempting to recommend pre- and post-exercise carbohydrate doses that at least match or exceed the amounts of protein consumed in these meals. However, carbohydrate availability during and after exercise is of greater concern for endurance as opposed to strength or hypertrophy goals.

Furthermore, the importance of co-ingesting post-exercise protein and carbohydrate has recently been challenged by studies examining the early recovery period, particularly when sufficient protein is provided. Koopman et al [ 52 ] found that after full-body resistance training, adding carbohydrate 0.

Subsequently, Staples et al [ 53 ] reported that after lower-body resistance exercise leg extensions , the increase in post-exercise muscle protein balance from ingesting 25 g whey isolate was not improved by an additional 50 g maltodextrin during a 3-hour recovery period.

For the goal of maximizing rates of muscle gain, these findings support the broader objective of meeting total daily carbohydrate need instead of specifically timing its constituent doses.

Collectively, these data indicate an increased potential for dietary flexibility while maintaining the pursuit of optimal timing.

But what is that something? That choice can make or break a workout. The majority of nutrients in a pre workout meal should come from carbohydrates, as these macronutrients immediately fuel the body. Some protein should be consumed as well, but not a significant amount, as protein takes longer to digest and does not serve an immediate need for the beginning of an activity.

Research has demonstrated that the type of carbohydrate consumed does not directly affect performance across the board Campbell et al. Regular foods are ideal e. Exercisers might also supplement with a piece of fruit, glass of low-fat chocolate milk or another preferred carbohydrate, depending on needs.

Pre-exercise fluids are critical to prevent dehydration. Before that, the athlete should drink enough water and fluids so that urine color is pale yellow and dilute-indicators of adequate hydration.

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.
