Description of intervention(s) / exposure
Women of exercise group performed muscular strengthening exercises of 60 minutes twice a week for three months. The exercise protocol consisted of warm-up, stretching, muscular strengthening of quadriceps, hamstring, calf muscle, paravertebral, and abdominal muscles as well as relaxing.
Muscular strength training started with 60% of one repetition maximum (1 RM) (2 series of 10-15 repetitions), achieving 85% until the end of the 3-month period (4 series of 6 repetitions each).
The exercise for the pelvic floor muscles consisted of performing 10 maximal contractions of the pelvic floor muscles kept for 6-8 seconds. At the end of a series of 10 contractions were performed three rapid contractions. The interval between a contractions was 6 seconds. The series were held in four positions: lying in the lateral, sitting, all fours and standing.
The exercise protocol was administered in groups up to 10 women by a physiotherapist.
