For endurance athletes, the protein recommendation is typically in the range of 1.2 to 1.4 grams of protein per kilogram of body weight per day. This level of protein intake supports the recovery, repair, and adaptation of muscle tissues that endurance athletes frequently require due to their high training volumes.

Endurance activities, such as long-distance running or cycling, predominantly rely on aerobic metabolism which can lead to muscle breakdown during prolonged exercise. Therefore, sufficient protein intake is essential for maintaining muscle mass and aiding in recovery processes, which helps improve performance and reduces the risk of injury.

While other options suggest higher protein intake, they are generally reserved for specific situations, such as muscle building or intense strength training where muscle hypertrophy is the primary goal. For endurance athletes, the recommended intake ensures they receive enough protein to support their specific recovery needs without excessive consumption that may not provide additional benefits in their training context.
