Birth control vs. natural cycle: muscle response to exercise
Part of Hormones & metabolism, Women’s health & pregnancy clinical trials.
This study compares how muscle protein responds to resistance exercise in women who use birth control pills versus those with natural menstrual cycles. Participants will do exercise sessions and have muscle samples taken to see how their bodies build protein.

This study tests whether simple body measurements can accurately predict muscle health in healthy young adults. It may help develop easier ways to assess muscle function without complex equipment.
This study compares how well your body uses protein from animal and microbial sources. It may help us understand which protein types are best for active, healthy adults.
This trial tests how different foods or diet patterns work together to help your body build more muscle protein. It’s designed for active, pre-menopausal women who are not pregnant and have regular cycles.
This study looks at how resistance training timed to your menstrual cycle affects muscle performance in women who have a natural cycle or take the pill.
This study examines how your menstrual cycle (or birth control pill) affects your athletic performance, health, and body. Researchers will compare female athletes with natural cycles to those using oral contraceptives to understand these differences better.
This study looks at how the menstrual cycle affects physical performance in active women. You track your cycle with an app and attend 3 lab visits to do exercise tests.
