Knowra Sports nutrition Sports nutrition Sports nutrition is the study and practice of nutrition strategies that support athletic performance, training, recovery, and health. It applies dietary science to the demands of exercise and sport.
Carbohydrate loading : A planned increase in carbohydrate intake that raises muscle glycogen before prolonged endurance exercise. It is used before long events to increase the carbohydrate available for working muscles.
Muscle glycogen : The stored form of glucose in muscle, used as a fuel source during exercise. Carbohydrate intake replenishes this limited fuel reserve between demanding sessions.
Sports dietitian : A dietitian with expertise in nutrition for exercise, training, and athletic competition. Sports dietitians translate nutrition evidence into individualized plans for athletes.
Ketogenic diet : A very-low-carbohydrate, high-fat diet that induces the production of ketone bodies. Its restricted carbohydrate supply conflicts with fueling approaches often used for intense exercise.
Sports drink : A beverage formulated to supply fluid and carbohydrate, often with electrolytes, during exercise. It combines hydration and fuel when exercise lasts long enough to make both useful.
Exercise-induced muscle damage : Temporary structural disruption in muscle after strenuous exercise, often accompanied by soreness and reduced function. Recovery nutrition is intended to support repair after the physical stress of training.
Macronutrient : A nutrient required in relatively large amounts, including carbohydrate, protein, and fat. These nutrients supply energy and materials needed for exercise and tissue maintenance.
Intermittent fasting : Eating patterns that alternate periods of fasting with periods of food intake. Its timing constraints can make it harder to meet training fuel and recovery needs.
Caffeine and athletic performance : The effects of caffeine on exercise performance, including alertness, perceived effort, and endurance. Caffeine is a widely used ergogenic aid with effects that depend on dose and timing.
Sweat rate : The rate at which a person loses fluid through sweating during activity. Estimating sweat losses helps tailor fluid replacement to an athlete and environment.
