Clinical Trial Summary

The goal of this clinical trial is to precise the impact of menstrual cycle and physical activity on the hamstrings muscle function in healthy active women. The main question it aims to answer is : is there a moment of the menstrual cycle when the muscle is better able to recover from a strenuous exercise ? Three appointments will be conducted to evaluate the hamstring muscles at difference moments of the menstrual cycle. Echographic and maximal force production measures will be done. Researchers will compare these results with a group taking oral contraceptives.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Hamstring muscles shear wave speed	Differences according to menstrual cycle phase in hamstring muscles shear wave speed, as measured by ultrasound elastography	Length of a menstrual cycle (around on 28 day average)
Secondary	Maximal voluntary force production	Differences according to menstrual cycle phase in maximal voluntary isometric hamstrings force production, as measured by an isokinetic dynamometer	Length of a menstrual cycle (around on 28 day average)
Secondary	Hamstring muscles thickness	Differences according to menstrual cycle phase in hamstring muscles thickness, as measured by ultrasound echography.	Length of a menstrual cycle (around on 28 day average)
Secondary	Hamstring muscles length of fascicles	Differences according to menstrual cycle phase in hamstring muscles fascicles' length, as measured by ultrasound echography.	Length of a menstrual cycle (around on 28 day average)
Secondary	Hamstring muscles pennation angle	Differences according to menstrual cycle phase in hamstring muscles pennation angle, as measured by ultrasound echography.	Length of a menstrual cycle (around on 28 day average)
Secondary	Hamstring muscles cross sectional area	Differences according to menstrual cycle phase in hamstring muscles cross sectional area, as measured by ultrasound echography.	Length of a menstrual cycle (around on 28 day average)
Secondary	Hamstring tendons length	Differences according to menstrual cycle phase in hamstring tendons length, as measured by ultrasound echography.	Length of a menstrual cycle (around on 28 day average)
Secondary	Maximal knee joint range of motion	Measure of the volunteer maximal knee range of motion, the maximum being defined by the volunteer as the greatest hip/leg angle reachable without feeling pain. The process is slowly conducted on an isokinetic ergometer by extending the knee joint (2°/s) until the volunteer reaches her maximal range of motion, at which point the movement is stopped and a security is placed.	Length of a menstrual cycle (around on 28 day average)
