The benefits of physical activity go beyond just burning off calories and can help preserve muscle as you lose weight and increase the proportion of muscle in the body. We also know that physical activity, and spending less time sitting, can reduce your risk of developing several chronic diseases, such as heart disease.

The main role of carbohydrates in physical activity is to provide energy. For athletes, if their diet does not contain enough carbohydrate, it is likely that their performance and recovery will be impaired, as carbohydrate is the key fuel for the brain and for muscles during exercise.

The body can store carbohydrates in the muscles and liver as glycogen and use these stores as a source of fuel for physical activity. These glycogen stores are limited, so for those training at a high level, it is important to be fully fuelled at the start of any exercise.

Glycogen is the main source of energy at the start of exercise and during short bursts of exercise. If you are doing high intensity training for long periods and your glycogen stores are not sufficient you may feel tired, lack energy and not be able to perform at your best.

So, regular intake of carbohydrate-rich foods can be important in this case to keep stores topped up. The correct food choices can help ensure the body has enough energy for activity, as well as help aid recovery.

Starchy foods are an important source of carbohydrates in our diet. Wholegrain varieties also provide fibre, and a range of vitamins and minerals including B vitamins, iron, calcium and folate.

Find out more about this topic on our pages on starchy foods, sugar and fibre. The amount of carbohydrate you need will depend on the frequency, type, duration and intensity of physical activity you do.

Competitive sports people and athletes will likely require more carbohydrates than an average gym user to match the intensity of their activity level. If you are active at around the current recommended levels minutes of moderate activity or 75 minutes of high intensity activity plus two sessions of muscle strengthening activities per week , then you can follow general healthy eating guidance to base meals on starchy carbohydrates, choosing wholegrain and higher fibre options where possible.

For information about portion sizes of starchy foods you can use our Get portion wise! portion size guide. At this level of activity, it is unlikely you will need to consume extra carbohydrates by eating more or by using products like sports drinks or other carbohydrate supplements, and these can be counterproductive if you are trying to control your weight as they will contribute extra calories.

Sports drinks also contain sugars, which can damage teeth. Regardless of your level of activity, you should try not to meet your requirements by packing your entire carbohydrate intake into one meal. Spread out your intake over breakfast, lunch, dinner and snacks that fit around planned exercise.

For athletes and individuals who are recreationally active to a higher level such as training for a marathon , consuming additional carbohydrate may be beneficial for performance. Athletes can benefit from having some carbohydrate both before and after exercise to ensure adequate carbohydrate at the start of training and to replenish glycogen stores post exercise.

In longer duration, high intensity exercise minutes or more , such as a football match or a marathon, consuming some carbohydrate during exercise can also improve performance, for example in the form of a sports drink.

Estimated carbohydrate needs are outlined below and depend on the intensity and duration of the exercise sessions International Olympics Committee :.

For example, from this guidance, someone who weighs 70kg doing light activity would need g carbohydrate per day whereas if they were training at moderate to high intensity for 2 hours a day, they would need g carbohydrate per day.

Protein is important in sports performance as it can boost glycogen storage, reduce muscle soreness and promote muscle repair. For those who are active regularly, there may be benefit from consuming a portion of protein at each mealtime and spreading protein intake out throughout the day.

As some high protein foods can also be high in saturated fat, for example fatty meats or higher fat dairy products, it is important to choose lower fat options, such as lean meats. Most vegans get enough protein from their diets, but it is important to consume a variety of plant proteins to ensure enough essential amino acids are included.

This is known as the complementary action of proteins. More information on vegetarian and vegan diets is available on our page on this topic. Whilst there may be a benefit in increasing protein intakes for athletes and those recreationally active to a high level, the importance of high protein diets is often overstated for the general population.

It is a common misconception that high protein intakes alone increase muscle mass and focussing too much on eating lots of protein can mean not getting enough carbohydrate, which is a more efficient source of energy for exercise.

It is important to note that high protein intakes can increase your energy calorie intake, which can lead to excess weight gain. The current protein recommendations for the general population are 0. If you are participating in regular sport and exercise like training for a running or cycling event or lifting weights regularly, then your protein requirements may be slightly higher than the general sedentary population, to promote muscle tissue growth and repair.

For strength and endurance athletes, protein requirements are increased to around 1. The most recent recommendations for athletes from the American College of Sports Medicine ACSM also focus on protein timing, not just total intake, ensuring high quality protein is consumed throughout the day after key exercise sessions and around every 3—5 hours over multiple meals, depending on requirements.

In athletes that are in energy deficit, such as team sport players trying to lose weight gained in the off season, there may be a benefit in consuming protein amounts at the high end, or slightly higher, than the recommendations, to reduce the loss of muscle mass during weight loss.

Timing of protein consumption is important in the recovery period after training for athletes. Between 30 minutes and 2 hours after training, it is recommended to consume g of protein alongside some carbohydrate.

A whey protein shake contains around 20g of protein, which you can get from half a chicken breast or a small can of tuna. For more information on protein supplements, see the supplements section. To date, there is no clear evidence to suggest that vegetarian or vegan diets impact performance differently to a mixed diet, although it is important to recognise that whatever the dietary pattern chosen, it is important to follow a diet that is balanced to meet nutrient requirements.

More research is needed, to determine whether vegetarian or vegan diets can help athletic performance. More plant-based diets can provide a wide variety of nutrients and natural phytochemicals, plenty of fibre and tend to be low in saturated fat, salt and sugar.

Fat is essential for the body in small amounts, but it is also high in calories. The type of fat consumed is also important.

Studies have shown that replacing saturated fat with unsaturated fat in the diet can reduce blood cholesterol, which can lower the risk of heart disease and stroke.

Fat-rich foods usually contain a mixture of saturated and unsaturated fatty acids but choosing foods that contain higher amounts of unsaturated fat and less saturated fat, is preferable as most of us eat too much saturated fat.

Find more information on fat on our pages on this nutrient. If I am doing endurance training, should I be following low carbohydrate, high fat diets? Carbohydrate is important as an energy source during exercise.

If a health professional you trust agrees that it's safe to diet, they can work with you to create a healthy eating plan. When it comes to powering your game for the long haul, it's important to eat healthy, balanced meals and snacks to get the nutrients your body needs.

The MyPlate food guide can guide you on what kinds of foods and drinks to include in your diet. Besides getting the right amount of calories, teen athletes need a variety of nutrients from the foods they eat to keep performing at their best.

These include vitamins and minerals. Calcium and iron are two important minerals for athletes:. Athletes may need more protein than less-active teens, but most get plenty through a healthy diet. It's a myth that athletes need a huge daily intake of protein to build large, strong muscles.

Muscle growth comes from regular training and hard work. Good sources of protein are fish, lean meats and poultry, eggs, dairy, nuts, soy, and peanut butter. Carbohydrates are an excellent source of fuel. Cutting back on carbs or following low-carb diets isn't a good idea for athletes.

That's because restricting carbs can make you feel tired and worn out, which can hurt your performance. Good sources of carbs include fruits, vegetables, and grains. Choose whole grains such as brown rice, oatmeal, whole-wheat bread more often than processed options like white rice and white bread.

Whole grains provide the energy athletes need and the fiber and other nutrients to keep them healthy. Sugary carbs such as candy bars or sodas don't contain any of the other nutrients you need.

And eating candy bars or other sugary snacks just before practice or competition can give athletes a quick burst of energy, but then leave them to "crash" or run out of energy before they've finished working out. Everyone needs some fat each day, and this is extra true for athletes.

That's because active muscles quickly burn through carbs and need fats for long-lasting energy. Like carbs, not all fats are created equal. Choose healthier fats, such as the unsaturated fat found in most vegetable oils, fish, and nuts and seeds.

Limit trans fat like partially hydrogenated oils and saturated fat, found in fatty meat and dairy products like whole milk, cheese, and butter. Choosing when to eat fats is also important for athletes.

Fatty foods can slow digestion, so it's a good idea to avoid eating them for a few hours before exercising. Sports supplements promise to improve sports performance.

But few have proved to help, and some may do harm. Anabolic steroids can seriously mess with a person's hormones , causing unwanted side effects like testicular shrinkage and baldness in guys and facial hair growth in girls. Steroids can cause mental health problems, including depression and serious mood swings.

Some supplements contain hormones related to testosterone, such as DHEA dehydroepiandrosterone. These can have similar side effects to anabolic steroids.

Other sports supplements like creatine have not been tested in people younger than So the risks of taking them are not yet known. The general recommendation for protein intake to support lean body mass and sports performance is around 0.

They fuel your daily functions, from exercising to breathing, thinking, and eating. The other half can come from simpler starches such as white rice, white potatoes, pasta, and the occasional sweets and desserts. For example, an ultramarathon runner will need a vastly different amount of carbs than an Olympic weightlifter does.

For example, if you consume 2, calories per day, this would equate to — g daily. From there, you can adjust your carbohydrate intake to meet the energy demands of your sport or a given training session.

In select cases, such as in keto-adapted athletes , they will provide a larger portion of daily energy needs. Fats are unique because they provide 9 calories per gram, whereas protein and carbs provide 4 calories per gram. In addition to providing energy, fats assist in hormone production, serve as structural components of cell membranes, and facilitate metabolic processes, among other functions.

Fats provide a valuable source of calories, help support sport-related hormones, and can help promote recovery from exercise.

In particular, omega-3 fatty acids possess anti-inflammatory properties that have been shown to help athletes recover from intense training.

After protein and carbohydrates, fats will make up the rest of the calories in your diet. Another notable factor to consider when optimizing your sports nutrition is timing — when you eat a meal or a specific nutrient in relation to when you train or compete.

Timing your meals around training or competition may support enhanced recovery and tissue repair, enhanced muscle building, and improvements in your mood after high intensity exercise.

To best optimize muscle protein synthesis, the International Society of Sports Nutrition ISSN suggests consuming a meal containing 20—40 g of protein every 3—4 hours throughout the day. Consider consuming 30—60 g of a simple carbohydrate source within 30 minutes of exercising. For certain endurance athletes who complete training sessions or competitions lasting longer than 60 minutes, the ISSN recommends consuming 30—60 g of carbs per hour during the exercise session to maximize energy levels.

But if your intense training lasts less than 1 hour, you can probably wait until the session is over to replenish your carbs. When engaging in sustained high intensity exercise, you need to replenish fluids and electrolytes to prevent mild to potentially severe dehydration.

Athletes training or competing in hot conditions need to pay particularly close attention to their hydration status, as fluids and electrolytes can quickly become depleted in high temperatures. During an intense training session, athletes should consume 6—8 oz of fluid every 15 minutes to maintain a good fluid balance.

A common method to determine how much fluid to drink is to weigh yourself before and after training. Every pound 0. You can restore electrolytes by drinking sports drinks and eating foods high in sodium and potassium.

Because many sports drinks lack adequate electrolytes, some people choose to make their own. In addition, many companies make electrolyte tablets that can be combined with water to provide the necessary electrolytes to keep you hydrated.

There are endless snack choices that can top off your energy stores without leaving you feeling too full or sluggish. The ideal snack is balanced, providing a good ratio of macronutrients, but easy to prepare. When snacking before a workout, focus on lower fat options , as they tend to digest more quickly and are likely to leave you feeling less full.

After exercise, a snack that provides a good dose of protein and carbs is especially important for replenishing glycogen stores and supporting muscle protein synthesis.

They help provide an appropriate balance of energy, nutrients, and other bioactive compounds in food that are not often found in supplement form. That said, considering that athletes often have greater nutritional needs than the general population, supplementation can be used to fill in any gaps in the diet.

Protein powders are isolated forms of various proteins, such as whey, egg white, pea, brown rice, and soy. Protein powders typically contain 10—25 g of protein per scoop, making it easy and convenient to consume a solid dose of protein.

Research suggests that consuming a protein supplement around training can help promote recovery and aid in increases in lean body mass. For example, some people choose to add protein powder to their oats to boost their protein content a bit.

Carb supplements may help sustain your energy levels, particularly if you engage in endurance sports lasting longer than 1 hour. These concentrated forms of carbs usually provide about 25 g of simple carbs per serving, and some include add-ins such as caffeine or vitamins.

They come in gel or powder form. Many long-distance endurance athletes will aim to consume 1 carb energy gel containing 25 g of carbs every 30—45 minutes during an exercise session longer than 1 hour.

Sports drinks also often contain enough carbs to maintain energy levels, but some athletes prefer gels to prevent excessive fluid intake during training or events, as this may result in digestive distress.

Many athletes choose to take a high quality multivitamin that contains all the basic vitamins and minerals to make up for any potential gaps in their diet. This is likely a good idea for most people, as the potential benefits of supplementing with a multivitamin outweigh the risks. One vitamin in particular that athletes often supplement is vitamin D, especially during winter in areas with less sun exposure.

Low vitamin D levels have been shown to potentially affect sports performance, so supplementing is often recommended. Research shows that caffeine can improve strength and endurance in a wide range of sporting activities , such as running, jumping, throwing, and weightlifting.

Many athletes choose to drink a strong cup of coffee before training to get a boost, while others turn to supplements that contain synthetic forms of caffeine, such as pre-workouts.

Whichever form you decide to use, be sure to start out with a small amount.
