AI-Summary
What this Trial Is About
With an increase in number of female athletes in sport events, it is becoming more important to gain insight in female related sports physiology. A main difference between male anf female athletes is the menstrual cycle. During the menstrual cycle, female reproductive hormones fluctuate. These hormones are also of influence on endurance, recovery, muscle strenght and mental state. Therefore we hypothesize that training efficiancy, power and motivation to train differ during the menstrual cycle. In case there is a pattern seen during the menstrual cycle, training programs can be individualized taking the menstrual cycle into account leading to more effective training programs.
