Menstrual cycle phases do not change vertical jump height in female football players

Female football players often wonder if their performance changes during different parts of their cycle. A new review looked at this question carefully. It examined seven studies involving female athletes. The main goal was to see if vertical jump height changed. This measure tracks how high an athlete can jump. The results showed no statistically significant differences were found between cycle phases. This means jump height stayed the same regardless of timing. The review noted some important limitations. There was substantial heterogeneity regarding how cycle phases were determined. Sample characteristics varied greatly across the studies. Testing protocols were not uniform. Methodological limitations in determining cycle phases also existed. Low statistical power was another concern. These factors mean findings should be interpreted cautiously. Current evidence is insufficient to determine whether cycle phases influence performance. Do not overstate the results. The data does not support higher jump values during specific phases. Athletes can train with confidence that their cycle does not alter this specific outcome.
