Experts have determined that extreme carbohydrate loading is unneccessary. Athletes can gradually increase their carbohydrate intake while reducing training load leading up to the race. Hyponatremia is not very common. Stachenfeld discusses strategies for susceptible athletes to prevent hyponatremia. Ingesting about grams of protein is sufficient to allow a maximal post-exercise muscle response.

Larger athletes may need to eat more protein after exercise because they require larger doses of protein to stimulate new protein synthesis.

Phillips recommends grams of protein to stimulate the rate of new muscle synthesis; however, the specific amount of protein within this range depends on the size of the athlete. Phillips explains why there is not a significant difference between protein isolates, concentrates and hydrosylates with respect to post-exercise recovery. An athlete has greater recovery needs since they usually expend more energy than the average population. Fatty acids found in fish oil and antioxidants found in red fruit and berries are important for brain development. Athletes can train their intestines to absorb carbohydrates during exercise, resulting in decreased GI problems and improved performance.

The sodium levels in pickle juice are very high, but it doesn't contain the right amount of fluid to rehydrate athletes. The best way for athletes to prevent heat cramps is to match sweat losses with fluid and sodium intake. Genetics attempts to link DNA variations to performance. Transcriptomics takes into account DNA and environmental factors, making it easier to detect differences in performance.

In the future, genomics may be able to help athletes personalize their training approach and predict injury-related responses. The most common nutrition mistake made by marathon runners is not practicing their race day nutrition plan during training. If their goal is to increase muscle mass, athletes may want to train later in the day. This timing may associate their training with their largest intake of amino acids. Relaxing at night will also help to decrease metabolic stress, which impairs adaptations to training. The night before a marathon is the last chance to fill muscle glycogen stores, so runners should choose foods high in carbohydrate.

Good options are rice, potatoes or pasta. The choice of what to eat for breakfast before a marathon is highly individual. The most important consideration is to get enough carbohydrate, at least g, to have enough fuel for the race. Endurance training will increase aerobic capacity, while strength training will increase muscle mass and alter the functionality of connective tissue.

Athletes looking to lose weight should balance energy intake and output, and eating before sleep is a personal preference. However, there could be an advantage to eating protein before sleep to promote protein synthesis. The biggest misconception about protein consumption is the notion that "more is better.

Biology - Proteins, Carbohydrates & Fats

Advice on the use of antioxidants depends on the type of training. Athletes should consume antioxidants during resistance training, but not endurance training. Individuals should consume fat in their diet since this nutrient is an important fuel source, aids vitamin absorption, acts as shock absorber for organs and is a component of membranes. During exercise fat stored in the muscle and adipose tissue supplies energy, so the type of dietary fat doesn't matter for performance.

However, good health saturated fats should be limited and omega-3 fatty acids encouraged. Carbohydrates are the main fuel source for an athlete during training, so this macronutrient should not be avoided when trying to lose weight. Sugar and salt, along with water and flavor, are the key components of a sports drink. Carbohydrates, including sugars, provide fuel and salt helps replace sweat losses.

The game of football involves repeated, short, high-intensity bursts of muscle contraction. The preferred energy source for burst or sprint activities is carbohydrate. Stop-and-go sports involve frequent transitions from one intensity to another. Therefore, the muscle relies heavily on carbohydrate as the main fuel source. Fluid needs during a race are highly individual and athletes should determine and practice their hydration strategy during training. The type of beverage to consume during a race is a personal decision.

However, for races of longer durations, athletes should include electrolytes. Athletes should also plan ahead and train with the beverages availabe on the course. It is also important the athlete is in positive energy balance and consumes additional calories from fat and carbohydrate. Due to the type of training stress and high energy expenditure, endurance athletes do not need to reduce protein intake to avoid gains in muscle mass. Dietary protein may help promote adaptations to endurance training. Information herein is intended for professional audiences, including scientists, coaches, medical professionals, athletic trainers, nutritionists, dietitians and other sports health professionals who have a fundamental understanding of human physiology.

The amount of carbohydrate needed during exercise varies depending on multiple factors Jeukendrup explains that the amount of carbohydrates needed during exercise depends on the intensity, type and duration of activity. The Two Categories of Carbohydrates Carbohydrate sources can be divided into two categories. Properties of anabolic post-exercise protein sources van Loon explains that rapidly digested and absorbed protein sources rich in the amino acid leucine, such as whey protein, are most anabolic following exercise.

The amount and type of carbohydrate athletes need for recovery van Loon explains the amount of carbohydrate needed after a workout and what sources athletes should look to consume. Why tired athletes may consume more calories Sleep-deprived people may consume more food. Avoiding GI Distress during a race Keys to avoiding GI distress include hydration and avoiding fiber, protein, fat and lactose rich foods. Foods that may cause GI distress Foods rich in fiber, protein, fat and lactose slow gastric emptying and should be avoided before and during exericse.

Non-nutritional causes of GI distress Movement of organs and decreased blood flow may contribute to GI issues during exercise.

Sports Nutrition: Facts on Carbohydrate, Fat and Protein

Determining risk for GI distress Factors that may increase an athlete's chance of experiencing GI distress. Tips to avoid GI distress During exercise of less than one hour, GI distress may be prevented by gargling rather than consuming carbohydrate. Many plant-based proteins are also high in fiber. Some fish and seafood sources come with a dose of Omega fatty acids.

Whey proteins offer the convenience of ease of preparation and portability. Those who strength train should aim for a minimum of 1 gram of protein per kilogram of bodyweight each day, according to a common recommendation. But the real gauge should be how well you recover after each training session or workout and how you are progressing toward your fitness goals. But a good place to start in figuring that out is understanding protein, fats, and carbohydrates so you and your clients can make informed decisions. Interested in becoming a go-to nutrition coach?

While too much Omega-6 may increase heart disease risk 1 , you need both for good health. EFAs are important for brain function, vision, cardiac health, skin and hair health, and fighting inflammation.

Supplements like fish and krill oil are also rich in Omega EFAs.

Monounsaturated fatty acids MUFAs — You can find this in a variety of foods and oils, including avocados, peanut butter, olive oil, and nuts. Found primarily in plant-based foods and oils, they help reduce heart disease risk by improving cholesterol profiles.


Too much in the diet can increase LDL and overall cholesterol levels, putting you at risk for heart disease. Sounds yummy, right? Even your favorite doughnut shop is probably using oils with trans fats to fry their donuts. Carbohydrates in the Garden of Good and Evil Carbs have recently become the nutritional devil, so to speak.

Carbohydrates come in a variety of forms, but for us, the most important are: Sugars — The simplest form of carbohydrate. Common varieties of sugars found in foods are fructose fruit sugar, sucrose table sugar , and lactose milk sugar. Fiber — Complex carbohydrates that come in soluble and insoluble varieties.

Both are important for digestion and cardiac health. Healthy Carbohydrates — Whole grains like rye, barley, and quinoa. Green leafy vegetables like lettuce, kale, and spinach. Veggies like broccoli, cauliflower, peppers, cucumbers, and zucchini. Fruits like apples, oranges, pears, berries, and melons.
