Biomechanical Changes During Menstrual Cycle

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.

Inclusion Criteria:

• Regular menstrual cycle lasting 28 days (+/- 5 days)
• A menstrual cycle that has been present for at least 2 years
• No hormonal contraception
• Lack of pain in the lower spine
• No restriction of mobility in the hip joint

Exclusion Criteria:

• Irregular menstrual cycle
• BMI value below 18.5 and above 25
• Orthopedic disorders in the lower limb
• Neurological disorders
• Normal flexibility of the hamstring muscles
