Effects of Respiratory Muscle Training on Heart, Lung, Metabolism, and Exercise in Adults After Bariatric Surgery

What this Trial Is About

Obesity, caused by excess body fat, is linked to chronic diseases and puts stress on the respiratory system, leading to breathing problems and reduced exercise ability. This research aims to find out how respiratory muscle training affects heart, lung, metabolic health, and physical fitness in patients who have undergone bariatric surgery. The study is a randomized clinical trial lasting 12 weeks and includes adults aged 18 to 60 who recently had bariatric surgery. Participants are divided into four groups combining two approaches institutionalized therapeutic exercise and inspiratory muscle training using a pressure threshold device, or their respective controls using a sham simulated device. Exercise includes aerobic and neuromuscular training with increasing intensities over 12 weeks. Inspiratory muscle training starts at 30% of maximum inspiratory pressure and increases to 60%, performed 5 times a week. Control groups receive sham training or usual care. Before and after the 12-week program, researchers will assess maximum inspiratory pressure, sleep apnea, walking distance, and sit-to-stand ability. Additional measures include sleep quality, heart rate, blood pressure, blood sugar control, lipid profile, body composition, quality of life, anxiety, depression, and risk of sleep apnea. The study tracks these outcomes to understand how respiratory muscle training influences health and exercise capacity after bariatric surgery.
