Protein intake varies among different types of athletes due to their specific training demands. Endurance athletes typically require 1.2 to 1.4 grams of protein per kilogram of body weight, focusing on recovery and muscle repair. In contrast, strength athletes may need higher amounts, around 1.6 to 2.2 grams, to promote muscle growth and maintenance. Therefore, tailoring protein intake to an athlete's training type and overall goals is vital for optimal performance and recovery.
