Traditionally, high impact exercise (including heavy weight lifting and running) has been discouraged in women with pelvic organ prolapse (POP). There is little research to support this, however, expert opinion hypothesised that high impact exercise results in significant increases in intra-abdominal pressure (IAP). This pressure may contribute to worsening POP symptoms by weakening the pelvic floor structures. This is a logical and reasonable assumption, however, is it correct?
