Open-close jumping may cause muscle contraction, but it will not cause uterine prolapse. The main cause of uterine prolapse is the loosening of the pelvic floor muscles and the ligaments during labor due to a large head during delivery, a long vaginal delivery, or multiple births. Uterine prolapse may also be associated with chronic coughing and constant increased abdominal pressure causing uterine prolapse, so ordinary exercise workouts, i.e., open and close jumping, will not cause uterine prolapse. The basic cause of uterine prolapse is due to relaxation of muscles and ligaments, and open and close jumping does not affect the muscles and ligaments of the pelvic floor in a bad way.
