Beneficial effect of glutamine on exercise-induced apoptosis of rat neutrophils.

Introduction/purpose: The effect of a single bout of intensive exercise on apoptosis of rat neutrophils and the possible prevention by glutamine administration was examined. The experiments were performed in sexually immature and sexually mature male rats as to examine the possible involvement of sexual maturation in the effect of exercise.

Methods: Exercise was carried out on a treadmill for 1 h before rats were killed by decapitation.
