Q

Enhance Resilience in Athletes: Role of Glutamine in Illness Prevention by Mika

relationship of Exercised-induced immunosuppression, athletes, and glutamine?

A

Strenuous exercise can deplete serum glutamine levels, as glutamine is used for energy and for tissue repair post-exercise. Lower glutamine availability can thus impair immune cell function, contributing to the temporary immunosuppression observed in endurance athletes and more susceptible to URTIs
