View clinical trials related to Oral Contraceptive Use.
Filter by: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.
There is still no one who has studied how oral contraceptive use affects recovery in trained women after repeated high-intensity workouts. Consequently, a well-controlled study is needed. The project is designed as a controlled cohort study, where 20 oral contraceptive users will be compared with 20 non-users. After initial preliminary examination and habituation to the test procedures, the subjects will start the intervention in week 2 of their menstrual cycle / active contraceptive pill cycle. Before and 3h, 24h and 48h after 3 intense strength training sessions performed 2 days in a row, blood samples will be taken, muscle soreness measured and performance tests performed. The day before the first training session and over the 4 trial days, the subjects will receive a standardized diet.
