Nutrition for competitive sports -
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.

The article looks at: Foods for fuel and exercise How to stay well hydrated Supplements. 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. Do I need to supplement protein to build muscle?
Protein: Protein has been a hot topic in sports and general nutrition for a long time. Protein recommendations for the general population are 0. Please note that you do not require expensive protein supplements to reach these recommendations.
The majority of people reading this post should have little problem meeting these requirements through a balanced diet. There is no evidence to suggest that the use of protein supplements will improve your muscle growth any better than protein from food when calorie intake is equal.
Protein is not a magical muscle builder, in order to make the most of your intake you must ensure you are consuming a sufficient amount of total calories. When it comes to post-training recovery, whether you are an elite or recreational athlete, adequate protein consumption has an important role to play.
Consuming about grams of protein, the amount in about 3-large eggs, with a post-training meal will help promote muscle recovery. Keep in mind that protein consumption in excess of this amount will most likely be used as an energy source for your body, rather than for muscle recovery ie: you might as well just have more carbohydrates instead.
Ideal animal protein sources include dairy, meat, eggs, fish or poultry whereas vegetarian athletes can turn to beans and tofu or other soy products. Remember to also include fluid and carbohydrates in your post-training meals.
Iron: Anyone who regularly engages in intense physical activity may have increased iron requirements. This may be especially true for female athletes, adolescents, vegetarians, long distance runners and anyone who restricts their intake of particular food groups without adequate planning.
If you fall into one of these categories you should ensure your health care practitioner regularly monitors your iron status. To learn more about iron requirements, iron-rich foods and iron absorption please have a look at the following Eat Right Ontario Iron Resource.
Other Micronutrients : Just like anyone else, athletes and active people are at risk of consuming a variety of nutrients at inadequate levels. Balancing training and competition commitments with everyday life, budgeting, work and school may leave less time and resources for food preparation.
Pressures to maintain a certain body weight or image may also contribute to unsafe food practices. If you often engage in extreme weight loss behaviours , restrict your calories or restrict certain food groups, you will be at even higher risker of micronutrient deficiency.
Vitamins and minerals that tend to be issues for athletes may include calcium, vitamin D, zinc, magnesium, vitamin C, vitamin E, the B vitamins and selenium. The quickest and best advice I can offer is you is to take a look at the Canadian Food Guide and ensure you are eating a great diversity of foods from each food group.
Diversifying your food intake is a great way to ensure balance in your micronutrient consumption. If you are a particularly high level athlete and you fear that your diet lacks adequacy or balance, you may consider having it reviewed more closely by a health professional as dietary shortcomings could potentially be harming your performance and your health.
Athletes and highly active people require more calories, particularly in the form of carbohydrates, to make up for energy use during exercise. It is most reasonable for athletes to seek extra calories from carbohydrate-based food groups such as grains, fruits and vegetables.
Athletes will certainly need to eat more foods from these groups than non-active individuals. Issues may arise when athletes are dissatisfied with their current body weight or body composition.
Depending on a great number of factors, altering your body weight or body composition could potentially improve your performance. This is highly dependent on the sport or activity that you are engaged in.
For example, in sports where speed is important a lighter, leaner composition may be advantageous. Regardless of your current status, it is very important that you do not engage in drastic weight loss behaviours.
Slight reductions to your caloric intake over time is the safest and best way to alter your body composition. Please keep in mind Altering your body composition takes time and severe restrictions to your calorie intake, especially during competition or training season, is dangerous:. You put yourself at risk of micronutrient deficiency which could have consequences on both your short and long-term health and wellbeing.
You put yourself at risk of caloric inadequacy, meaning you are not consuming enough energy to fuel your body for your athletic endeavours and risk severe detriment to your performance and physical progress.
If you are satisfied with the way you perform in your current state, you should not feel the need to make drastic changes. As training intensity increases, it is generally wise to ensure food consumption follows suit to ensure you are adequately fueled. A special note for any parents or coaches out there, it is never recommended to urge adolescents to diet as this could be detrimental to their physical and mental development, as well as their performance.
Hydration: Hydration is perhaps the single most important topic in sports nutrition. Aside from an increased calorie requirement, an increased fluid requirement is the other nutritional factor that distinguishes athletes from the general public. Athletes and active people need to consume extra fluids before, during and after exercise to account for fluid losses through sweat and to maintain adequate hydration status.
As a general rule, it is best to make a concious effort to consume water regularly throughout the day while paying special attention to your hydration status before games or events. It is recommended to consume between ml of water per kg of body weight at least 4 hours before sporting or training events.
This will allow your body to be in optimal performing condition. Once activity begins, fluid loss through sweat becomes important, particularly in endeavours of greater than an hour in duration where sweat losses may be higher. Sports drinks, which contain both carbohydrates and sodium, are an ideal hydration aid in such instances whereas water may be more suitable in endeavours an hour or under.
If you are a salty sweater, this may contribute to muscle cramping and decreased performance during physical activity. In such cases, consuming sports drinks with high sodium levels rather than water may be an even more important strategy to aid in your performance.
There is so much more to hydration and hydration science than I can do justice to in the time and space that I have alotted for this blog posting.
The doctor can work with you or refer you to a dietitian to develop a healthy eating plan for your young athlete. Kids need to eat well on game days.
The meal itself should not be very different from what they've eaten throughout training. Athletes can choose healthy foods they believe enhance their performance and don't cause any problems like stomach upset.
Athletes need to eat the right amount and mix of foods to support their higher level of activity. But that mix might not be too different from a normal healthy diet. Eating for sports should be another part of healthy eating for life.

Calcium and iron are two important minerals for athletes: Calcium helps build strong bones to resist breaking and stress fractures. Calcium-rich foods include low-fat dairy products like milk, yogurt, and cheese, as well as leafy green vegetables such as broccoli. Iron helps carry oxygen to all the different body parts that need it.
Iron-rich foods include lean meat, chicken, tuna, salmon, eggs, dried fruits, leafy green vegetables, and fortified whole grains. Protein: Protein helps build and repair muscles, and most kids get plenty of it through a balanced diet. Protein-rich foods include fish, lean meat and poultry, dairy products, beans, nuts, and soy products.

However, this form co,petitive nutritionis not applicable for spofts athlete and in every situation. The Ntrition of Liver detoxification program nutrition requires involvement with the particular type of sports, an athlete's current training stage, and athletes' individual requirements and objectives. Implementation takes time and individual motivation on the part of athletes and the specialist staff who engage intensively with the nutritional needs of athletes. In addition to adequate energy provision, it is important to divide the energy sensibly among the energy sources carbohydrates, fats, and protein. Performance athletes' higher need for protein can usually be covered in their regular diet; supplements are needed only in exceptional cases.Nutrition for competitive sports -
Beverages and foods that count toward daily water intake:. Athletes need to pay special attention to their pre-match meal and beverage choices, as these foods and fluids may need to last for hours during longer match play.
Examples of pre-match meals and beverages rich in carbohydrate and fluids are pasta, sandwiches, fresh fruit, granola bars, higher carbohydrate energy bars, sports drinks and fitness waters. These do not hydrate as well and act as diuretics.
Have a minimum of two liters available courtside. Thirst is not an accurate indicator of hydration level. To keep performing at your best, drink 7 to 10 oz of fluid every 10 to 15 minutes. Favor sports drinks to enhance rehydration. Sports drinks contain carbohydrate and electrolytes, like sodium.
Consuming carbohydrate during play has been shown to help players maintain more power and accuracy in serving and groundstrokes in long match play. For example, Gatorade contains 14 g carbohydrate per 8 oz, which is quickly absorbed and used by working muscles.
Sodium replacement is also important since a significant amount of sodium can be lost through sweat during play. Recent research also shows that sports players can loose a great deal of sodium during long play in the heat, some male players losing up to 2 grams of sodium in a single session!
Eat foods and drink fluids that replenish muscle energy stores and electrolytes lost in competition. Here are some guidelines to follow:. Begin by drinking a sports drink or fitness water as you walk off the court or field.
A simple way to check this is to check your body weight both before and after a match to note the body weight change. Trying a fruit smoothie with protein powder or a sports meal replacement shake at this time can aid with this as well as provide some additional hydration. Drink 1 — 2 cups of water-based beverages water, juice, milk with every meal and snack.
Target a 10 — 12 cup base minimum of these hydrating beverages per day. The Dietary Guidelines for Americans, — suggest that the optimal macronutrient ratios for adults are as follows:.
The International Sports Sciences Association ISSA notes that people can adjust these ratios based on the goal of physical activity. For example, an endurance athlete would increase the amount of carbohydrates they eat, while a strength athlete would increase their protein intake.
According to a review by the International Society of Sports Nutrition ISSN , typical macronutrient ratios for athletes are as follows:. Carbohydrates receive a great deal of attention in sports nutrition due to the vital role they play in athletic performance. Carbohydrates are typically the preferable fuel source for many athletes, particularly for high intensity and long duration exercise.
This is because they supply ample glycogen storage and blood glucose to fuel the demands of exercise. To maintain liver and muscle glycogen stores, athletes will need different amounts of carbohydrates depending on their exercise volume.
For example, an athlete weighing kg who performs high volume intense training would look to consume roughly 1,—1, g of carbohydrates.
Protein also plays an essential role in sports nutrition, as it provides the body with the necessary amount of amino acids to help build and repair muscles and tissues. Athletes doing intense training may benefit from ingesting more than two times the recommended daily amount RDA of protein in their diet.
For example, the dietary reference intake for adult females is 46 g, and for adult males — 56 g. That is why it may be beneficial for athletes to consume nearer to 92 g and g of protein, respectively.
The ISSA suggests that many athletes can safely consume 2 g of protein per 1 kg of body weight daily, compared with the RDA of 0. The ISSN also notes that optimal protein intake may vary from 1.
Higher amounts of protein can help athletes avoid protein catabolism and slow recovery, which the ISSN notes can contribute to injuries and muscle wasting over time.
For moderate amounts of intense training, an athlete should consume 1. For high volume intense training, the ISSN suggests 1. Healthy protein sources include:. Fats are essential in the diet to maintain bodily processes, such as hormone metabolism and neurotransmitter function.
Including healthy fats in the diet also helps satiety and can serve as a concentrated fuel source for athletes with high energy demands. Some athletes may choose to eat a ketogenic diet and consume higher amounts of fats. Healthy fat sources include oily fish , olive oil , avocados , nuts, and seeds.
Athletes should ensure they consume the essential vitamins and minerals they need to support their general health and sports performance. People can usually achieve adequate intakes of essential vitamins and minerals by eating a varied, balanced diet.
Some athletes may choose to take vitamin or mineral supplements or ergogenic aids, such as creatine. The ISSN recommends that consumers evaluate the validity and scientific merit of claims that manufacturers make about dietary supplements.
There is little evidence to support the efficacy or safety of many dietary supplements, including:. However, scientists have shown that other ergogenic aids, such as caffeine and creatine monohydrate, are safe and effective for athletes.
It is important to be aware that some athletic associations ban the use of certain nutritional supplements.
Moreover, athletes should ensure they maintain adequate hydration. Given that sweat losses are a combination of fluids and electrolytes, such as sodium and potassium, athletes may choose to and benefit from using sports drinks, milk , or both to meet some of their hydration needs.
The ISSN suggests that athletes training intensely for 2—6 hours per day 5—6 days of the week may burn over — calories per hour while exercising. As a result, athletes engaging in this level of activity may require 40—70 calories per 1 kg of body weight per day, compared with the average less active individual, who typically requires 25—35 calories per 1 kg of body weight daily.
According to the ISSN, athletes weighing 50— kg may require 2,—7, calories per day. It also notes that athletes weighing — kg may need to consume 6,—12, calories daily to meet training demands.
The timing and content of meals can help support training goals, reduce fatigue, and help optimize body composition.
Guidelines for the timing and amount of nutrition will vary depending on the type of athlete. For example, the ISSN advises strength athletes consume carbohydrates and protein or protein on its own up to 4 hours before and up to 2 hours after exercise.
The American College of Sports Medicine ACSM also notes the importance of consuming protein both before and after exercise for strength athletes. By contrast, endurance athletes would need to consume mostly carbohydrates and a small amount of protein roughly 1—4 hours before exercise.
Both the ISSN and ACSM emphasize the role of meal timing in optimizing recovery and performance and recommend athletes space nutrient intake evenly throughout the day, every 3—4 hours.
Some people may find that consuming meals too close to the beginning of exercise can cause digestive discomfort. It is therefore important to eat an appropriate amount and not exercise too quickly after eating. People who are training or racing at peak levels may find it challenging to consume enough food for their energy requirements without causing gastrointestinal GI discomfort, especially immediately before an important workout or race.
For example, the ISSA highlights the importance of hydration and carbohydrate loading for competitive swimmers. At the same time, it emphasizes consuming easily digestible carbohydrates, such as bananas and pasta, prior to events to avoid GI discomfort.
Athletes may need to work with a sports nutritionist, preferably a registered dietitian , to ensure they consume enough calories and nutrients to maintain their body weight, optimize performance and recovery, and plan a timing strategy that suits their body, sport, and schedule.
Athletes need to eat a healthy and varied diet that meets their nutrient requirements. Choosing whole grains and other fiber -rich carbohydrates as part of a daily diet generally promotes health. However, immediately prior to and during intense trainings and races, some athletes may prefer simpler, lower fiber carbohydrates to provide necessary fuel while minimizing GI distress.
The following is an example of what an athlete might eat in a day to meet their nutritional needs. Breakfast: eggs — either boiled, scrambled, or poached — with salmon , fresh spinach , and whole grain toast or bagel.
Lunch: stir-fry with chicken or tofu, brown rice , broccoli , green beans , and cherry tomatoes cooked in oil. Dinner: a baked sweet potato topped with turkey, bean chili, or both, served with a watercress , peppers, and avocado salad drizzled with olive oil and topped with hemp seeds.
Athletes will have different sporta needs compared with the general public. Strategies for long-term success may require more calories and Nutritiion to maintain Nootropic for Cognitive Decline and spotrs to compete at their optimum Liver detoxification program. In addition to consuming sufficient amounts of calories cmopetitive macronutrients, Liver detoxification program Njtrition also require more vitamins, minerals, and other nutrients for peak recovery and performance. In this article, we discuss macronutrient and micronutrient needs of athletes and look at calories, meal timing, and how to tailor requirements to specific sports. We also give meal examples for breakfast, lunch, and dinner. Having a suitable diet provides a person with enough energy and nutrients to meet the demands of training and exercise. In addition to helping a person perform optimally, it facilitates recovery.
