Enrollment: 500
Sex: FEMALE
Minimum age (years): 20
Maximum age (years): 26
Standard ages: ADULT
Accepts healthy volunteers: yes
Allocation: NA
Intervention model: SINGLE_GROUP
Primary purpose: BASIC_SCIENCE

Brief 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.

* 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
