Menstrual Cycle Impact on Performance

The menstrual cycle, which lasts about 28 days, causes hormonal fluctuations that can affect physical performance. During the first half (follicular phase), increased estrogen may enhance strength and endurance. Around ovulation, energy levels often peak. In the second half (luteal phase), rising progesterone can lead to fatigue, mood changes, and increased perception of effort, potentially reducing performance. Understanding these cycles can help athletes plan training and competition around times of optimal performance and manage symptoms that might hinder their activity.
