Age-related differences in the neuromuscular performance of fatigue-provoking exercise under severe whole-body hyperthermia conditions.

Neuromuscular performance during fatigue-provoking sustained isometric exercise under severe whole-body hyperthermia conditions appears to decline in both age groups, but a lower relative decline in torque production for older males may relate to lower psychological and thermophysiological strain along with a diminished dopamine response and prolactin release.
