What are macronutrients and how do they contribute to sports nutrition?

Macronutrients are nutrients that provide energy in the form of calories and include carbohydrates, proteins, and fats. Carbohydrates are the body’s primary source of fuel during exercise, proteins are essential for muscle repair and growth, and fats provide energy and support hormone production. Balancing macronutrient intake is important for optimizing energy levels, supporting muscle function, and promoting recovery in athletes.
