For those involved in endurance sports, protein intake must be adjusted to support muscle repair and recovery. While general recommendations suggest 0.8 grams of protein per kilogram of body weight, endurance athletes may require 1.2 to 1.4 grams per kilogram. This increase accounts for the high level of physical stress and muscle breakdown experienced during prolonged activities. Consuming adequate protein not only aids recovery but also helps maintain lean muscle mass, supports metabolic function, and enhances overall athletic performance.
