Clinical Trial Summary

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.

• Hamstring Muscles
• Menstrual Cycle
• Passive Stretching

Intervention

Procedure:
• Static stretching
Static stretching lasting 3 x 45 seconds will be performed in each of the examined women three times in different phases of the menstrual cycle: follicular, ovulatory and luteal. Before and after the intervention, a series of tests assessing the influence of stretching on biomechanical parameters will be carried out

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.
