Role of nutrition in performance enhancement and postexercise recovery

Updated by: Linda J. Editorial team. Nutrition and athletic performance. You are more likely to be tired and perform poorly during sports when you do not get enough: Calories Carbohydrates Fluids Iron, vitamins, and other minerals Protein. However, the amount of each food group you need will depend on: The type of sport The amount of training you do The amount of time you spend doing the activity or exercise People tend to overestimate the amount of calories they burn per workout so it is important to avoid taking in more energy than you expend exercising.

Complex carbohydrates are found in foods such as pasta, bagels, whole grain breads, and rice. They provide energy, fiber , vitamins, and minerals. These foods are low in fat.

Simple sugars , such as soft drinks, jams and jellies, and candy provide a lot of calories, but they do not provide vitamins, minerals, and other nutrients. What matters most is the total amount of carbohydrates you eat each day. A little more than half of your calories should come from carbohydrates.

You can satisfy this need by having: Five to 10 ounces to milliliters of a sports drink every 15 to 20 minutes Two to three handfuls of pretzels One-half to two-thirds cup 40 to 55 grams of low-fat granola After exercise, you need to eat carbohydrates to rebuild the stores of energy in your muscles if you are working out heavily. People who exercise or train for more than 90 minutes should eat or drink more carbohydrates, possibly with protein, 2 hours later. Try a sports bar, trail mix with nuts, or yogurt and granola For workouts lasting less than 60 minute, water is most often all that is needed.

But it is also a myth that a high-protein diet will promote muscle growth. Only strength training and exercise will change muscle. Athletes, even body builders, need only a little bit of extra protein to support muscle growth. Athletes can easily meet this increased need by eating more total calories eating more food.

Amino acid supplements and eating a lot of protein are not recommended. Some ideas for keeping enough fluids in the body include: Make sure you drink plenty of fluids with every meal, whether or not you will be exercising.

Drink about 16 ounces 2 cups or milliliters of water 2 hours before a workout. It is important to start exercising with enough water in your body. Water is best for the first hour. Switching to an energy drink after the first hour will help you get enough electrolytes.

Choose skinless chicken or turkey or remove the skin. Shopping Take time when food shopping and read food labels carefully to help you choose foods that are lower in saturates.

How to stay well hydrated Sufficient fluid intake is essential for exercise and optimum recovery. The amount an individual sweats varies from person to person and depends on: Intensity and duration — longer and higher intensity exercise can cause greater sweat loss. Environmental temperature — in hot, humid conditions sweat loss can increase. Clothing — the more clothing that is worn, the quicker you are likely to heat up which may cause greater sweat loss. Genetics — some people are just more likely to sweat than others. Generally, the more a person sweats, the more they will need to drink.

For more information on healthy hydration click here Putting nutrition into practice The timing of eating and exercising can be important for how you feel and perform during your chosen activity. Before: Ideally, your pre-exercise meal should be low in fat and contain a portion of starchy foods, such as porridge, pasta or potatoes, and should be around hours before exercising. For example , if you have an exercise class at 5pm, have your pre-exercise meal at around 2pm.

You could eat a small snack between your pre-exercise meal and exercise to top up energy levels. If you do, it is best to wait minutes before taking part in any vigorous sports or exercise. Making sure you are well hydrated before you start an exercise session is important, so try to drink regularly throughout the day and with your pre-exercise meal.

During : Consuming some carbohydrates during exercise can enhance performance but this generally only applies to individuals participating in endurance or high intensity sports that last over 60 minutes, as this is when carbohydrate stores may substantially decrease e. Try to sip small amounts of fluids whenever possible during exercise to stay hydrated.

Keep sipping water before and during the activity, if possible, to keep hydration levels topped up. After : Food and fluid intake is also important for optimum recovery after exercise. After a long run or exercise class, your carbohydrate stores will be lower, so it is important to replenish them, especially if you are doing more exercise later on that day or the following day.

The post-exercise meal should be based on starchy foods preferably wholegrain and include some high quality, lean protein. Consuming this as soon as possible after exercise will be most beneficial for recovery, restoring glycogen levels and muscle protein. If you are unable to have a meal soon after exercise, try to have a small snack that contains carbohydrate and protein, such as a banana and a glass of low fat milk, within the first minutes following exercise to begin the recovery process, especially if you have exercise within the next eight hours.

To replace the fluid lost from sweating, it is vital to restore hydration levels as part of recovery, so remember to drink plenty of fluids after exercising. Tips to plan your meals and snacks:. Preparation - your pre-exercise meal, whether it is breakfast or lunch, should be around hours before and include a good amount of starchy foods to ensure you have enough fuel in the tank.

A small snack minutes before exercise can help to top up energy levels. Connect with us Foodafactoflife. BNF Nutrition. Subscribe to our newsletter! Full Name Required field.
