Open for Recruitment
Many women develop irregular menstrual cycles which may make it difficult to become pregnant and increase the risk of osteoporosis. Why do exercise and diet have this effect in some women but not others? This study will help us understand how nutrition, exercise, and the environment affect women's reproductive cycles.
Participants will be asked to track three consecutive menstrual cycles and come in for 9-10 visits on specific days. Participants will undergo two 5-day exercise and diet regimens provided by the study. Procedures include a physical exam, fitness testing, measurement of body fat and bone density, blood sampling, and daily at home blood & urine tests.
Participants will be compensated for their time.
