In athletes, the increased need for protein is best explained by which of the following?

• A. Decreased protein oxidation
• B. Increased need for tissue repair
• C. Caloric restriction
• D. Protein quality differences

Answer: (B)

When athletes train, their muscles experience microtrauma that must be repaired and remodeled. Repairing damaged fibers and building new ones requires amino acids from dietary protein, so the body's demand for protein rises to support recovery and adaptation. This increased need is driven by tissue repair and growth processes that follow training, not by lower protein oxidation, calorie shortfalls, or simply protein quality. Protein oxidation can fluctuate with energy use, and while adequate calories and high-quality protein support recovery, the main reason for higher protein needs is the ongoing need to repair and remodel tissue after exercise.
