Menstrual Cycle Clinical Trial
Official title:
Biomechanical Changes in Young Women During Menstrual Cycle
The aim of the work is to assess the effect of the menstrual cycle on the biomechanical properties of the muscles. The study will be conducted among young women aged 20-25 with a regular menstrual cycle. During the test, muscle strength and muscle flexibility as well as activation times will be performed. The study will assess the effect of the stretching of the hamstring muscles on the biomechanical properties of the muscles in the different phases of the menstrual cycle.

Primary | Hamstring passive stifness | Hamstring stiffness will be assessed using TDK test. During the test the resistance of the elongated Hamstring muscle is measured. If the resistance value is smaller after the intervention it means that muscle stiffness changed. | Change measured before and immediately after static stretching during follicular phase of menstrual cycle | |
