Effects of sleep restriction on hormonal responses to resistance training are unclear

Determine how acute and chronic sleep restriction modulate endocrine responses to resistance training in humans, including testosterone, cortisol, growth hormone, and IGF‑1 dynamics during and after exercise.

Background

Sleep loss is known to impair performance and recovery, but its specific impact on the hormonal milieu elicited by resistance training is not well characterized. Resolving this uncertainty is important for athletes and populations with chronically restricted sleep.
