MECA_CYCLE: Characterization of the Mechanical Properties of the Hamstring Muscle Group in Female.
Study Details
Study Description
Brief 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.

| Experimental: Menstrual cycle group Women who are not currently taking any form of hormonal contraception and who present a regular menstrual cycle. |
Diagnostic Test: Hamstring muscles function assessment
Ultrasound echographic evaluation of the hamstring muscles during stretching and voluntary contractions, before and after a strenuous physical activity.

Outcome Measures
Primary Outcome Measures
- Hamstring muscles shear wave speed [Length of a menstrual cycle (around on 28 day average)]
Differences according to menstrual cycle phase in hamstring muscles shear wave speed, as measured by ultrasound elastography
Secondary Outcome Measures
- Maximal voluntary force production [Length of a menstrual cycle (around on 28 day average)]
Differences according to menstrual cycle phase in maximal voluntary isometric hamstrings force production, as measured by an isokinetic dynamometer
- Hamstring muscles thickness [Length of a menstrual cycle (around on 28 day average)]
Differences according to menstrual cycle phase in hamstring muscles thickness, as measured by ultrasound echography.
- Hamstring muscles length of fascicles [Length of a menstrual cycle (around on 28 day average)]
Differences according to menstrual cycle phase in hamstring muscles fascicles' length, as measured by ultrasound echography.
- Hamstring muscles pennation angle [Length of a menstrual cycle (around on 28 day average)]
Differences according to menstrual cycle phase in hamstring muscles pennation angle, as measured by ultrasound echography.
- Hamstring muscles cross sectional area [Length of a menstrual cycle (around on 28 day average)]
Differences according to menstrual cycle phase in hamstring muscles cross sectional area, as measured by ultrasound echography.
- Hamstring tendons length [Length of a menstrual cycle (around on 28 day average)]
Differences according to menstrual cycle phase in hamstring tendons length, as measured by ultrasound echography.
- Maximal knee joint range of motion [Length of a menstrual cycle (around on 28 day average)]
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.
