Nutrient timing for athletes -

To effectively implement nutrient timing, an understanding of macronutrient metabolism, energy systems, and exercise physiology is important. The metabolic fates of proteins, fats, and carbohydrates during rest, exercise, and recovery are imperative to science. While research on the manipulation of fats exists, specific timing strategies have yet to show clear and repeated success when augmenting performance or recovery.

These windows focus largely on glycogen availability in the muscles, or how saturated the muscles are with carbohydrates. It also considers the digestion and absorption rate of specific nutrients, and substrate utilization during exercise.

Moderate to high-intensity exercise relies heavily on carbohydrates as a fuel source, however, glycogen stores in the body are limited and can only supply the body with energy for up to a few hours during continued high-intensity bouts. Therefore, "filling up the gas tank" is imperative to improve performance and prevent fatigue.

It takes roughly about hours for carbohydrates to be fully digested and assimilated into muscle and liver glycogen. Therefore, the first feeding priority before exercise is a meal at least 4 hours before competition to fully saturate muscle glycogen stores.

Muscle recovery goals will vary based on the sport an athlete is participating in but can include muscle strength, muscle growth, or prevention of muscle soreness.

Since muscles store carbohydrates and amino acids make up the structure of skeletal tissues, feedings are largely focused on carbohydrates and proteins. When studies compared the effects of carbohydrate or protein feedings on muscle protein synthesis, they found that together they have the greatest effect on increasing muscle protein synthesis.

Regarding muscle strength and growth, it has been found that the greatest effect of protein consumption is largely dependent on the last dose consumed.

Regular protein feedings every hours in doses of grams have shown the greatest benefit in improving muscle growth, and strength and leading to favorable changes in body composition. However, regarding specific feeding windows, muscle protein synthesis is greatest immediately after up to 2 hours post-exercise.

How much protein should be consumed in that time frame? Can essential amino acids also do the trick?

Doses of g of essential amino acids can also maximally stimulate muscle protein synthesis. This can improve recovery and leads to favorable changes in body composition such as increases or maintenance in lean mass and decreases in fat mass. During exercise, frequent feedings of g of high GI carbs per hour of training can help increase performance, maintain normal blood glucose levels, and prevent early fatigue.

Post-exercise, protein should be consumed as soon as possible after exercise. However, you can still maximally stimulate muscle protein synthesis up to 2 hours post-exercise by consuming g of a rich protein.

When it comes to strength, recovery, and improved body composition it is recommended that protein be consumed in intervals of every hours to promote a positive state of nitrogen balance. If your goal is to build muscle, carbohydrates, and protein should be consumed together. Nutrient timing can be employed at any level, however, if you are looking to gain a competitive edge and boost your performance, nutrient timing may be the key to your success.

Her first introduction to working with professional athletes was back in when she worked at the UFC performance institute in Las Vegas, Nevada. Since then, Jackie has worked with various professional fighters and other clientele and now operates under her company she started back in March, The Fight Nutritionist LLC.

The Fight Nutritionist is dedicated to providing the most effective nutrition plans to ensure her athletes are performance at their absolute best. It also breaks down how to time protein intake. In an editorial published by Nutrition , it explains that nutrition timing is based on three phases:.

Energy phase : This is when the muscle releases enough energy to contract during exercise. Carbohydrate consumption at this time helps keep muscle glycogen stores from depleting. It also helps keep blood sugar from crashing. This reduces fatigue.

Add protein to the mix and muscle can exert more effort. It also stunts the rise of cortisol, aiding in muscle recovery. Anabolic phase : The 45 minutes after a workout is the anabolic phase. This is when damaged muscle protein starts to repair.

Muscle glycogen stores are starting to restore. During this phase, insulin sensitivity initially increases, then drops rapidly. Several hours after exercise, insulin resistance can occur.

This can slow muscle recovery and repair. Growth phase : The growth phase starts after the anabolic stage ends and continues until a new workout begins. Muscle hypertrophy occurs during this phase. Muscle glycogen is also fully replenished. While timing nutrition may seem like a lot of work, it does get easier with practice.

Plus, there are quite a few benefits in timing your meal or snack. Nutrient timing can help maximize muscle growth. A study reported that consuming whey protein after lower-body resistance training contributed to greater rectus femoris muscle size.

Timing your nutrition can also aid in fat loss. One study found that consuming a 1;1. Another study reports that nutrient timing also affects metabolism.

If the goal is improved performance, nutrition timing can help with this too. Research supports pre-exercise carbohydrate consumption for endurance athletes.

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.
