Comparing the effectiveness of circadian rhythm and menstrual period on the recovery of a session of exhausting activity in inactive young women
Design
Clinical trial with one group, experimental group in follicular phase and luteal phase conditions in a crossover manner in the morning and evening
Settings and conduct
The exercise testing protocol will be as follows: First warm up - adopt a standard warm up protocol: 5 minutes of cycling at 50-60 rpm with load = 2% of body weight, rest before the Wingate test. A shorter warm up (5-10 minutes) at submaximal effort is sufficient for experienced athletes and then perform the Wingate protocol - maintain the seat height and ergometer calibration throughout the sessions. The resistance load should be 0.075 kg/kg body weight for women. Provide strong verbal encouragement.
