What is a proven effect of glutamine on post-exercise recovery?

Glutamine is an amino acid that plays a significant role in recovery following exercise. Its primary function related to post-exercise recovery revolves around its ability to aid in restoration and storage processes within the body. After intense physical activity, one of the body's priorities is to replenish glycogen stores and repair muscles. Glutamine helps to facilitate these processes by supporting the maintenance of nitrogen balance, aiding in protein synthesis, and promoting glycogen replenishment in muscles.

During periods of physical stress, such as after exercising, the body’s demand for glutamine may increase, and supplementation can assist in ensuring that adequate levels are available to support recovery. This involvement is particularly beneficial for athletes and those engaged in heavy training, as it contributes to faster recovery times, reduced muscle soreness, and better overall performance in subsequent workouts.

The other choices might suggest beneficial effects related to endurance, strength, or fat storage, but they do not accurately reflect the most supported and documented effect of glutamine on post-exercise recovery. The primary emphasis of research has been on its role in restoration and glycogen storage rather than the other factors listed.
