A nutrient required in large amounts, such as carbohydrates, proteins, and fats, essential for energy and bodily functions. Carbohydrate
A primary energy source, especially during high-intensity exercise, and crucial for replenishing glycogen stores. Protein
A macronutrient vital for muscle growth, repair, and preservation, with increased needs for athletes. Fat
A macronutrient used for energy, but not preferred during high-intensity activity; intake should remain moderate. Glycogen
A stored form of carbohydrate in muscles and liver, serving as a critical energy reserve during exercise. Meal Timing
The strategic scheduling of food intake before and after exercise to optimize energy, recovery, and performance. Carbohydrate Loading
A strategy used by endurance athletes to maximize muscle glycogen stores in preparation for prolonged events. Micronutrient
A nutrient needed in small amounts, such as vitamins and minerals, supporting metabolic and physiological functions. Antioxidant
A compound, like vitamins E and C, that neutralizes free radicals produced during physical activity. B Vitamin
A group of micronutrients essential for metabolizing carbohydrates and fats to produce ATP for muscle activity. Calcium
A mineral important for muscle contraction and bone structure, with increased needs in physically active individuals. Iron
A mineral necessary for hemoglobin formation and oxygen transport, especially important for athletes. Energy Requirement
The total amount of energy needed daily, which increases with physical activity, especially for athletes. Saturated Fat
A type of fat that, when consumed in excess, can increase disease risk, even in high-performance athletes. Glycogen Replenishment
The process of restoring muscle carbohydrate stores after exercise, optimized by post-exercise carbohydrate intake.
