AVALIAÇÃO DE FORÇA DO ASSOALHO PÉLVICO E DA COMPOSIÇÃO CORPORAL DE MULHERES PRATICANTES DE EXERCÍCIOS INTERMITENTES DE ALTA INTENSIDADE: ESTUDO TRANSVERSAL

Abstract

Background: The high intensity intermittent exercise (HIIE) has conquered many followers, especially women. Despite the benefits of this practice on energy expenditure and physical conditioning, it is not known whether the practice is beneficial on the pelvic floor. Theoretically, strenuous physical exercise can increase intra-abdominal pressure and is a risk factor for the development of pelvic floor disorders. Objective: To evaluate the pelvic floor and body composition of women who practice HIIE with and without urinary symptoms. Methods: Cross-sectional study, composed of adult women practicing HIIE. Participants answered a questionnaire that assesses the occurrence and severity of urinary incontinence and underwent analysis of the bioelectrical activity of the pelvic floor using Miotool electromyography equipment from Miotec and body composition analysis using bioimpedance. Results: Eleven women with a mean age of 37.81±5.39 years and modality practitioners for 26.90±16.97 months participated in this study. With 4 (36.3%) women without and 7 (63.6%) with urinary symptoms. There was a significant difference between the following EMG parameters: mean intensity of tonic contractions in uv (G1= 40.522±7.37 µv versus G2=26.50±12.69 µv p=0.004) time before peak (G1= 0.36±0 .25 sec versus G2=2.12±1.37 sec p=0.034) and time after the peak of tonic contractions (G1=0.60 ±0.20 sec versus G2=6.5±1.97 sec p= 0.004). Conclusion: The results of this study reinforce that the presence of urinary tract symptoms in these women is associated with a deficit in tonic fibers, where less bioelectrical activity can be observed, a delay in the onset of contractions and less capacity to maintain the tonic contraction over time.
