Acute Deep Water Running Response and Linear Load Inspiratory Exercise in Overweight/Obese and Slim Adults: Randomized Study

Abstract

Introduction: Obesity causes several clinical manifestations, whether orthopedic, respiratory and cardiovascular, so aquatic and respiratory exercise are therapeutic options. Goal: To compare the acute effect of the use of linear inspiratory booster in subjects submitted to deep water running (DWR). Methods: Prospective, randomized study, single session of continuous exercise, DWR and respiratory exercise (PowerBreathe Classic, 50% Maximal Inspiratory Pressure -IMR), water temperature 32 to 36°C, in adults of both sexes, thin and overweight/obese. The subjects were divided into two DWR and DWR+TMI. Body mass index (BMI), anklebrachial index (ABI) and cardiorespiratory measures were evaluated. Data will be analyzed by normality test, dependent and independent t test, Wilcoxon and MannWhitney (p<0.05). Results: Eleven volunteers were evaluated, 8 (72.7%) were female Age: 27.00±9.56 years, BMI: 25.21±7.47 kg/m2, lean mass: 49.07±17.36 kg, Body fat: 20.79±11.84 kg, ABI: 1.01±0.02 mmHg. The DWR group had a 9 bpm increase in heart rate after exercise. Conclusion: DWR associated with IMT does not promote acute cardiorespiratory changes in young adults.
