Metrics details. Nutrient timing for muscle growth groqth is a mucsle nutritional strategy that Lentils and vegetables the muscel of combinations of nutrients--primarily protein and carbohydrate--in and around an exercise session. Some have claimed that this approach can produce dramatic improvements in body composition. It has even been postulated that the timing of nutritional consumption may be more important than the absolute daily intake of nutrients. The post-exercise period is widely considered the most critical part of nutrient timing.

Nutrient timing for muscle growth -

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. Growth hormone also increases protein synthesis Volek, The Three Nutrient Timing Phases The nutrient timing system is split into three distinct phases: 1 Energy Phase just before and during workout 2 Anabolic Phase post 45 minutes of workout 3 Growth Phase remainder of the day The Energy Phase Muscle glycogen is the primary fuel followed by fat used by the body during exercise.

Low muscle glycogen stores result in muscle fatigue and the body's inability to complete high intensity exercise Levenhagen et al. The depletion of muscle glycogen is also a major contributing factor in acute muscle weakness and reduced force production Haff et al.

Both aerobic and anaerobic exercise decrease glycogen stores, so the need for carbohydrates is high for all types of exercise during this energy phase. Several hormonal and physiological responses occur during the energy phase.

Prior to aerobic exercise, protein intake with carbohydrate supplementation has been shown to stimulate protein synthesis post-exercise Volek et al. Carbohydrate supplementation prior to resistance training can increase the body's capacity to perform more sets, repetitions and prolong a resistance training workout Haff et al.

The Anabolic Phase: The Minute Optimal Window The anabolic phase is a critical phase occurring within 45 minutes post-exercise. It is during this time that muscle cells are particularly sensitive to insulin, making it necessary to ingest the proper nutrients in order to make gains in muscle endurance and strength.

If the proper nutrients are ingested 2 - 4 hours post-exercise they will not have the same effect. It is also during this time in which the anabolic hormones begin working to repair the muscle and decrease its inflammation. Immediate ingestion of carbohydrate is important because insulin sensitivity causes the muscle cell membranes to be more permeable to glucose within 45 minutes post-exercise.

This results in faster rates of glycogen storage and provides the body with enough glucose to initiate the recovery process Burke et al. Muscle glycogen stores are replenished the fastest within the first hour after exercise.

Consuming carbohydrate within an hour after exercise also helps to increase protein synthesis Gibala, The Growth Phase The growth phase consists of the 18 - 20 hours post-exercise when muscle repair, growth and strength occur.

According to authors Ivy and Portman, the goals of this phase are to maintain insulin sensitivity in order to continue to replenish glycogen stores and to maintain the anabolic state. Consuming a protein and carbohydrate meal within 1 - 3 hours after resistance training has a positive stimulating effect on protein synthesis Volek, Carbohydrate meals with moderate to high glycemic indexes are more favorable to enhance post-exercise fueling.

Higher levels of glycogen storage post-exercise are found in individuals who have eaten high glycemic foods when compared to those that have eaten low glycemic foods Burke et al. Nutrient Timing Supplement Guidelines: Putting it Together for Yourself and Your Clients Aquatic instructors expend a lot of energy in teaching and motivating students during multi-level fitness classes.

Clearly, nutrient timing may be a direction the aquatic profession may choose to pursue to determine if it provides more energy and faster recovery from a challenging teaching load.

As well, some students and clients may seek similar results. From the existing research, here are some recommended guidelines of nutrient timing.

It may be even more critical when resistance training according to an article in the Journal of Athletic Performance and Nutrition.

This article explains that it works by reducing protein degradation and increasing protein synthesis. Some research even suggests that the timing of other substances may offer more benefits.

A study looked at the timing of ergogenic aids and micronutrients. It noted that timing caffeine, nitrates, and creatine affect exercise performance. 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. At the same time, this professional can help with more than just nutrient timing.

They can offer advice on calorie intake, how to create a balanced meal, and more. You can offer this advice yourself by becoming a certified nutrition coach.
