What this trial studies

This observational study aims to explore the relationship between menstrual cycle phases and training loads in both elite and non-elite female athletes. By recruiting 200 competitive premenopausal female athletes, the study will track various performance metrics, hormonal responses, and health indicators over a year. Participants will be assessed at three different training load phases to evaluate how these factors influence athletic performance, injury prevalence, and overall health. The findings could help tailor training programs to better suit female athletes' physiological needs.

Why it matters

Potential benefit: If successful, this study could lead to improved training strategies and health outcomes for female athletes.

How similar studies have gone: While there is limited longitudinal data specifically addressing this topic, similar studies have shown promising results in understanding the impact of hormonal fluctuations on athletic performance.
