Effects of Hypopressive Abdominal Training on Ventilatory Capacity and Quality of Life: A Randomized Controlled Trial.

Pelvic floor dysfunctions, associated with alterations in respiratory mechanics and, consequently, quality of life, are the cause of the most frequent gynecological problems. Pelvic floor muscle training emerges as a first-line treatment, with new approaches such as hypopressive exercises. The aim of this study was to analyze the efficacy of an 8-week supervised training program of hypopressive exercises on the pelvic floor and its impact on improving the ventilatory mechanics and quality of life in women. Analysis of the spirometric parameters showed a significant main Group × Time effect for three parameters: the ratio of FEV/FVC ( = 0.030), the forced expiratory flow at 75% of the expired vital capacity ( < 0.001), and the forced expiratory flow over the middle half of the forced vital capacity ( = 0.005). No statistical significance was found regarding the SF-12 questionnaire components; only differences were found over time in the physical role ( = 0.023), bodily pain ( = 0.001), and vitality ( < 0.010) domains and in the physical component summary score ( = 0.010). After an 8-week intervention of hypopressive exercises, an improvement in the ventilatory and pulmonary capacities can be observed.
