Exercise for Better Bones – Day or Night?
Why are we doing this Study?
We know that humans have biological rhythms with the change of day and night cycle and these rhythms affect short- and long-term physiological and physical performance. The purpose of this study is to research the effects of the early morning vs early evening exercise on bone and related changes. We expect to find out whether the timing of exercise affects bone health.
