Protein needs for athletes can be calculated based on weight, activity level, and training intensity. Generally, athletes require a higher protein intake than sedentary individuals, with recommended levels ranging from 1.2 to 2.0 grams of protein per kilogram of body weight, depending on their sport and training goals. Endurance athletes may aim for the lower end of this range, while strength and power athletes often require more. Additionally, ensuring a balanced protein intake throughout the day supports better muscle recovery and growth.
