Nutrient timing for performance -
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!

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. If you have no appetite post-exercise, a recovery beverage may be a good option. To recover quickly and completely, your body needs healthy fuel like the choices shown here-beginning within 30 minutes of your session's end.

When to Start Replenishing Carbs AFTER exercise Training generally depletes muscle glycogen. What About PROTEIN? REHYDRATE Effectively With Fluids and Sodium Virtually all weight lost during exercise is fluid, so weighing yourself without clothes before and after exercise can help gauge net fluid losses.
Listen to Your Body's Timing Signals 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.
Consume only small amounts of protein; limit fats and fiber see these foods that are high in fiber that you should avoid! Hydration: At least 4 hours before an activity, aim for milliliters of water per kilogram of body weight.
Timing: Ideal for most people is to eat hours before an activity, up to about 1, nutritious calories. Consume calories if lead time is much shorter e. The classic nutrient timing train of thought has been to consume carbohydrate before a workout and protein afterward.
While this approach is logical, is it supported by current research? Some may argue that we actually have it backwards, and that protein is more effective prior to a workout. Furthermore, timing is not crucial as long as we consume adequate calories and nutrients within a hour period. Digestion, which is the process of breaking large food molecules into smaller ones, takes place primarily in the stomach.
Absorption, which is the process of up-taking nutrients into the blood stream and lymph system, takes place primarily in the small intestine. Utilizing nutrients carbohydrate, fat, protein, water, vitamins and minerals is directly related to the rate of gastric emptying, which is the time it takes to digest foods and release them from the stomach into the intestines.
Meals that are high in protein, fat or fiber and concentrated meals stay in the stomach longer and therefore absorb more slowly. Carbohydrates, liquids and semi-solid foods leave the stomach relatively quickly and absorb more rapidly. Enzymes are proteins that speed up reactions in the body and are essential components to digestion as well as exercise metabolism.
Physical activity triggers a number of reactions in the body and activates enzymes such as glycogen phosphorylase and glycogen synthase, which are responsible for turning glucose blood sugar into glycogen stored carbohydrate.
These enzymes remain active in the muscles for 30 to 60 minutes following exercise, and fuel consumed within this window can restore glycogen twice as fast as a meal consumed two hours later. The aforementioned anabolic window is a result of heightened enzyme activity following a workout.
During this time frame, your body is more likely to turn your shake or food into carbohydrate both in the muscles and liver rather than fat. Intense or long-duration exercise depletes muscle glycogen and breaks down muscle tissue protein. Therefore, the goal of post-exercise fueling is to replace muscle glycogen and begin regenerating muscle tissue.
Adequate carbohydrate and protein feeding post-exercise helps restore glycogen and protein stores, respectively. An important consideration, however, is how long it takes to utilize the energy we consume; carbohydrate can digest, absorb and subsequently raise blood glucose within 15 to 30 minutes.
Protein, on the other hand, digests more slowly and does not lead to peak amino acid levels in the blood for up to three hours. Thus, consuming protein two to three hours before the end of your workout one to two hours prior, in most cases could result in more rapid tissue regeneration post-workout.
But protein still plays an important role post-exercise, as it helps carbohydrate with its role. The addition of protein to carbohydrate increases insulin production.
Insulin is a hormone that facilitates the uptake and storage of carbohydrates and amino acids read more about hormones here.
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.
A recent trend in fitness and athletics is a push for real food instead of pills, powders and bars. 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.
