简要总结
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.

研究组 & 干预措施
Young women during various of phases of menstrual cycle.
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.
干预措施: Static stretching (Procedure)
结局指标
主要结局
Hamstring flexibility
时间窗: Change measured before and immediately after static stretching during luteal phase of menstrual cycle
Hamstring flexibility will be assessed using AKE and PKE and SLR tests.
Hamstring passive stifness
时间窗: Change measured before and immediately after static stretching during luteal phase of menstrual cycle
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.
Trunk acivity is assessed using Stabilizer Pressure Biofeedback
时间窗: Three repetitions with a 30-second break between. The measure is taken during luteal phase of menstrual cycle
The torso activation scheme is measured during lower and upper limb motions using Chattanooga Stabilizer Pressure Biofeedback.
Passive Hamstring flexibility
时间窗: Change measured before and immediately after static stretching during luteal phase of menstrual cycle
Hamstring flexibility will be assessed using PKE test
Active Hamstring flexibility
时间窗: Change measured before and immediately after static stretching during luteal phase of menstrual cycle
Hamstring flexibility will be assessed using SLR tests.
Hamstring strength is tested using the Micro Fet Handheld Dynamometer.
时间窗: Change measured before and immediately after static stretching. The measure is taken during luteal phase of menstrual cycle
Muscle strength of hamstring is tested. Three repetitions of muscle strength testing are performed with two 30-second intervals. The participants are asked to press against the Dynamometer with the maximum effort for 5-7 seconds.
Strength of arm flexors and extensors and hip flexors is tested using the Micro Fet Handheld Dynamometer.
时间窗: Three repetitions for 5-7 seconds with two 30-second intervals . The measure is taken during luteal phase of menstrual cycle
