Nutrition for sports performance -
They may require more calories and macronutrients to maintain strength and energy to compete at their optimum level. In addition to consuming sufficient amounts of calories and macronutrients, athletes may 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.
Athletes may need to consider :. 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. 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. Choosing the right foods, zeroing in your macros, optimizing meal timing, ensuring good hydration, and selecting appropriate snacks can help you perform at your best.

But is it worth the hype? Our registered dietitian breaks…. There's no one set guide for how much water to drink. How much fluid each person needs depends on their age, size, level of physical activity, and environmental temperature. Athletes should drink before, during, and after exercise.
Don't wait until you feel thirsty, because thirst is a sign that your body has needed liquids for a while. Sports drinks are no better for you than water to keep you hydrated during sports.
But if you exercise for more than 60 to 90 minutes or in very hot weather, sports drinks may be a good option. The extra carbs and electrolytes may improve performance in these conditions. Otherwise your body will do just as well with water.
Avoid drinking carbonated drinks or juice because they could give you a stomachache while you're training or competing. Don't use energy drinks and other caffeine -containing drinks, like soda, tea, and coffee, for rehydration. You could end up drinking large amounts of caffeine, which can increase heart rate and blood pressure.
Too much caffeine can leave an athlete feeling anxious or jittery. Caffeine also can cause headaches and make it hard to sleep at night. These all can drag down your sports performance. Your performance on game day will depend on the foods you've eaten over the past several days and weeks.
You can boost your performance even more by paying attention to the food you eat on game day. Focus on a diet rich in carbohydrates, moderate in protein, and low in fat. Everyone is different, so get to know what works best for you.
