Which of the following is NOT a role of nutrition in athletic performance?

The correct answer highlights that building muscle exclusively is not the sole role of nutrition in supporting athletic performance. While nutrition certainly plays a significant role in muscle repair and growth, this is just one aspect of a broader nutritional spectrum that impacts performance.

Nutrition serves multiple functions for athletes, which include providing essential vitamins and minerals that support various metabolic processes, aiding in fuel production for exercise to ensure energy is available for performance, and facilitating recovery after exertion to help maintain overall athletic readiness. Each of these roles is critical for optimal athletic function and longevity in sport. In contrast, the notion of building muscle exclusively oversimplifies the multifaceted role of nutrition, as athletic performance encompasses energy management, recovery, nutritional support, and overall health beyond just muscle hypertrophy.
