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. You can gradually increase your dose as long as your body tolerates it. Supplementing with omega-3 fats such as fish oil may improve sports performance and recovery from intense exercise.
You can certainly get omega-3s from your diet by eating foods such as fatty fish, flax and chia seeds, nuts, and soybeans. Plant-based omega-3 supplements are also available for those who follow a vegetarian or vegan diet.
Creatine is a compound your body produces from amino acids. It aids in energy production during short, high intensity activities. Supplementing daily with 5 g of creatine monohydrate — the most common form — has been shown to improve power and strength output during resistance training, which can carry over to sports performance.
Most sporting federations do not classify creatine as a banned substance, as its effects are modest compared with those of other compounds. Considering their low cost and wide availability and the extensive research behind them, creatine supplements may be worthwhile for some athletes.
Beta-alanine is another amino acid-based compound found in animal products such as beef and chicken. In your body, beta-alanine serves as a building block for carnosine, a compound responsible for helping to reduce the acidic environment within working muscles during high intensity exercise.
The most notable benefit of supplementing with beta-alanine is improvement in performance in high intensity exercises lasting 1—10 minutes. The commonly recommended research -based dosages range from 3.
Some people prefer to stick to the lower end of the range to avoid a potential side effect called paraesthesia , a tingling sensation in the extremities.
Sports nutritionists are responsible for implementing science-based nutrition protocols for athletes and staying on top of the latest research. At the highest level, sports nutrition programs are traditionally overseen and administered by registered dietitians specializing in this area.
These professionals serve to educate athletes on all aspects of nutrition related to sports performance, including taking in the right amount of food, nutrients, hydration, and supplementation when needed.
Lastly, sports nutritionists often work with athletes to address food allergies , intolerances , nutrition-related medical concerns, and — in collaboration with psychotherapists — any eating disorders or disordered eating that athletes may be experiencing.
One of the roles of sports nutritionists is to help debunk these myths and provide athletes with accurate information. Here are three of the top sports nutrition myths — and what the facts really say.
While protein intake is an important factor in gaining muscle, simply supplementing with protein will not cause any significant muscle gains.
To promote notable changes in muscle size, you need to regularly perform resistance training for an extended period of time while making sure your diet is on point. Even then, depending on a number of factors, including genetics, sex, and body size, you will likely not look bulky.
Another common myth in sports nutrition is that eating close to bedtime will cause additional fat gain. Many metabolic processes take place during sleep.
For example, eating two slices of pizza before bed is much more likely to result in fat gain than eating a cup of cottage cheese or Greek yogurt. Coffee gets a bad rap for being dehydrating. While sports nutrition is quite individualized, some general areas are important for most athletes.

Water is essential for life and hydration is important for health, especially in athletes and those who are physically active, who will likely have higher requirements.
Drinking enough fluid is essential for maximising exercise performance and ensuring optimum recovery. Exercising raises body temperature and so the body tries to cool down by sweating.
This causes the loss of water and salts through the skin. Generally, the more a person sweats, the more they will need to drink. Average sweat rates are estimated to be between 0.
Dehydration can cause tiredness and affect performance by reducing strength and aerobic capacity especially when exercising for longer periods. So, especially when exercising at higher levels or in warmer conditions, it is important to try and stay hydrated before, during and after exercise to prevent dehydration.
In most cases, unless training at a high intensity for over an hour, water is the best choice as it hydrates without providing excess calories or the sugars and acids found in some soft drinks that can damage teeth.
For more information on healthy hydration see our pages on this topic. For those who are recreationally active to a high level, or for athletes, managing hydration around training or competition is more important.
The higher intensity and longer duration of activity means that sweat rates tend to be higher. Again, the advice for this group would be to ensure they drinks fluids before, during and after exercise.
Rehydration would usually involve trying to drink around 1. Below are some examples of other drinks, other than water that may be used by athletes, both recreational and elite. Sports drinks can be expensive compared to other drinks; however it is easy to make them yourself!
To make your own isotonic sports drink, mix ml fruit squash containing sugar rather than sweeteners , ml water and a pinch of salt. Supplements are one of the most discussed aspects of nutrition for those who are physically active. However, whilst many athletes do supplement their diet, supplements are only a small part of a nutrition programme for training.
For most people who are active, a balanced diet can provide all the energy and nutrients the body needs without the need for supplements. Sports supplements can include micronutrients, macronutrients or other substances that may have been associated with a performance benefit, such as creatine, sodium bicarbonate or nitrate.
The main reasons people take supplements are to correct or prevent nutrient deficiencies that may impair health or performance; for convenient energy and nutrient intake around an exercise session; or to achieve a direct performance benefit.
Whilst adequate amounts of protein and carbohydrate are both essential in maximising performance and promoting recovery, most people should be able to get all the nutrients they need by eating a healthy, varied diet and, therefore, supplements are generally unnecessary.
For athletes, supplementing the diet may be beneficial, possibly on performance, on general health or for reducing injury and illness risk.
However, there is not much research on many of the commonly used supplements, and there are only a small number of supplements where there is good evidence for a direct benefit on performance, including caffeine, creatine in the form of creatine monohydrate , nitrate and sodium bicarbonate.
Even in these cases, the benefits on performance vary greatly depending on the individual and there is only evidence for a benefit in specific scenarios.
This means that any athletes considering supplementation will need to weigh the potential benefits with the possible negative impacts, such as negative effects on general health or performance, risk of accidental doping or risks of consuming toxic levels of substances such as caffeine.
The advice to consider supplementation for a performance benefit is for high performance athletes and should be carried out alongside expert advice from qualified sports nutritionists or dietitians. It is a common myth that consuming lots of excess protein gives people bigger muscles.
Quite often, people taking part in exercise focus on eating lots of protein, and consequently may not get enough carbohydrate, which is the most important source of energy for exercise.
The main role of protein in the body is for growth, repair and maintenance of body cells and tissues, such as muscle. Fifteen to 25g of high-quality protein has been shown to be enough for optimum muscle protein synthesis following any exercise or training session, for most people, and any excess protein that is ingested will be used for energy.
The recommendations for daily protein intake are set equally for both endurance training and resistance training athletes, so higher intakes are not recommended even for those exclusively trying to build muscle.
Any more protein than this will not be used for muscle building and just used as energy. Therefore, whilst among recreational gym-goers protein supplementation has become increasingly popular for muscle building, it is generally unnecessary. However, after competition or an intense training session, high quality protein powders can be a more convenient and transportable recovery method when there is limited access to food or if an individual does not feel hungry around exercise, and may be effective for maintenance, growth and repair of muscle.

Eating well for physical activity and sport can have many benefits including: allowing you to perform well in your chosen sport or activity reducing the risk of injury and illness ensuring the best recovery after exercise or a training programme However, the dietary patterns that will best suit an individual will depend on the amount and intensity of activity.
Physical activity when losing weight Doing physical activity will increase your energy expenditure the calories you use , as energy is required during exercise to fuel the contracting muscles, increased breathing and heart rate and metabolism.
Foods for fuel and exercise Carbohydrates Protein Vegetarian and vegan diets for athletes Fat Carbohydrates The main role of carbohydrates in physical activity is to provide energy. The table below shows the carbohydrate content of some common foods: Food source Serving size Carbohydrate content g per serving size Wholewheat pasta boiled g Protein Protein is important in sports performance as it can boost glycogen storage, reduce muscle soreness and promote muscle repair.
The table below shows the protein content of some common foods: Food source Serving size Protein content g per serving size Chicken breast grilled g Fat Fat is essential for the body in small amounts, but it is also high in calories.
How to stay well hydrated Water is essential for life and hydration is important for health, especially in athletes and those who are physically active, who will likely have higher requirements. The amount an individual sweats varies from person to person and depends on: intensity and duration of exercise — 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 sweat more than others. Sports drinks: sports drinks contain carbohydrates in the form of glucose, as well as electrolytes such as sodium.
Sodium will replace any lost from sweating and enhance rehydration, and glucose will replenish carbohydrate stores. Sports drinks have been shown to help endurance performance and recovery for active individuals performing endurance exercise over a longer duration 60 minutes or more e.
participating in a marathon. However, it is important to remember that sports drinks are like other soft drinks that contain sugars. This means that they can be high in calories and contribute to tooth decay, so they are only suitable if taking part in high-level endurance sports or if sweat loss is high.
Milk: Skimmed or semi-skimmed milk has been used in some studies as a post-exercise recovery drink. It contains minerals that can replace those lost via sweating, as well as providing nutrients involved in muscle function and bone health potassium and calcium.
It also naturally contains high quality protein and some carbohydrate in the form of lactose and is relatively cheap to buy.
Energy drinks: are not designed to replace the electrolytes lost in sweat and may contain other ingredients with stimulant properties, such as caffeine. As some are high in sugars, they can increase the risk of tooth decay and contain energy, which may cause weight gain if consumed in excess.
Supplements Supplements are one of the most discussed aspects of nutrition for those who are physically active.

For every pound grams you lose while exercising, you should drink 16 to 24 ounces to milliliters or 3 cups milliliters of fluid within the next 6 hours. Changing your body weight to improve performance must be done safely, or it may do more harm than good. Keeping your body weight too low, losing weight too quickly, or preventing weight gain in an unnatural way can have negative health effects.
It is important to set realistic body weight goals. Young athletes who are trying to lose weight should work with a registered dietitian. Experimenting with diets on your own can lead to poor eating habits with inadequate or excessive intake of certain nutrients. Speak with a health care professional to discuss a diet that is right for your sport, age, sex, and amount of training.

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 ten 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. PROTEIN Protein is important for muscle growth and to repair body tissues.
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.
Too much protein in the diet: Will be stored as increased body fat Can increase the chance for dehydration not enough fluids in the body Can lead to loss of calcium Can put an added burden on the kidneys Often, people who focus on eating extra protein may not get enough carbohydrates, which are the most important source of energy during exercise.
