Details and patient eligibility

About

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.

Young women during various of phases of menstrual cycle.

Experimental group

Description:

The group of 40 young women will have their hamstring muscle stretched in different phases of the menstrual cycle: follicular, ovulatory and luteal. Static stretching will last 3x 45 seconds with a 15 second break between repetitions. Before and after the intervention a series of tests will be performed.

Treatment:

Procedure: Static stretching
