Knowra Sports drink Sports drink A beverage formulated to replace fluids and electrolytes, often with carbohydrates, during or after physical exercise. Its composition can support fluid absorption and provide fuel during prolonged exertion.
Hydration : The process of supplying the body with water to maintain normal physiological function. Sports drinks are designed partly to restore water lost through sweat.
Osmolality : A measure of the concentration of dissolved particles per kilogram of solvent. Drink osmolality helps explain how carbohydrate concentration can affect intestinal water movement.
Endurance exercise : Physical activity sustained over an extended period, relying substantially on aerobic energy production. Long sessions can make drinkable carbohydrate and fluid replacement useful.
Water : A chemical compound made of hydrogen and oxygen, essential as a solvent and body fluid. For shorter or less strenuous activity, water often replaces fluid without added sugar or electrolytes.
Sports nutrition : The study and practice of nutrition strategies that support exercise, performance, and recovery. Sports drinks are one tool within broader plans for training fuel and fluid intake.
Electrolyte : A substance that produces electrically charged ions when dissolved in water or melted. Their dissolved ions, especially sodium, are the minerals sports drinks aim to replace.
Gastric emptying : The movement of stomach contents into the small intestine. A drink must leave the stomach before much of its fluid and carbohydrate can be absorbed.
Exercise-associated hyponatremia : A dangerously low blood sodium concentration occurring during or after prolonged exercise. Drinking excessive fluid, including sports drink, can still dilute blood sodium.
Energy drink : A beverage marketed to increase alertness or energy, commonly containing caffeine and other stimulants. Energy drinks target stimulation, whereas sports drinks primarily target fluid and fuel replacement.
Added sugar : Sugars added to foods or beverages during processing or preparation. Frequent consumption outside exercise can add substantial sugar to the diet.
