Performance During Menstrual Cycle

This project aims to investigate if muscle strength and muscle power fluctuate during the menstrual cycle.

The hypothesis is that the greatest performance will be measured right before ovulation, and at it's lowest on day 1 and 2 of the menstrual cycle in women not using any form for hormonal protection.

And that the performance in women using birth control pills, not will variated in the period where they are taking pills (day 1-21).
