Abstract
The pelvic-floor muscles like any other muscle groups require regular exercise to maintain their function. A The pelvic-floor muscles, like any other muscle group, require regular exercise to maintain their function. A comprehensive health-enhancing training programme should include both strengthening and relaxing exercises for pelvic-floor muscles. The aim of this study was to answer the question whether a 6-week training based on strengthening and relaxing pelvic-floor muscles, performed under a supervision of an instructor or unsupervised, will improve their level of neuromuscular activity? The study participants were 45 female students of the Gdansk University of Physical Education and Sport in Gdansk (AWFiS) – healthy nulliparas at the age of 23 ± 3 y (M ± SD), randomly assigned to two groups. In group 1 (n = 14) women were trained 3 times a week under the supervision of an instructor, performing pelvic-floor muscle exercises integrated into high-low aerobic classes. Group 2 (n = 31) exercised without supervision, according to a written training plan. Before and after 6-week training in both groups we assessed the level of neuromuscular activity for the pelvic-floor muscles using surface electromyography (sEMG) with TeleMyo DTS Noraxon EMG and Sensors System (Scottsdale, AZ, USA) and vaginal probes. Two analysed training interventions appeared to be effective for the increase in pelvic-floor muscle EMG activity during contractions and its decrease during releasing. These results encourage recommending pelvic-floor muscle exercises both in the form of "home exercise" and incorporated into fitness classes.
