Abstract
Background - Obese individuals with focus on weight reduction, neglecting the overall skeletal muscle performance, including respiratory muscles(RM) during Aerobic training. As altered respiratory muscle performance in the ensuing years may lead to respiratory muscle inefficacy, increasing work of breathing, reducing pulmonary functions; predisposing to obesity hyperventilation syndrome, obstructive sleep apnoea and reduced exercise tolerance. Purpose – The study assessed whether whole body endurance training affects respiratory muscle strength or we need to focus on RM Strengthening alongwith weight management as a separate entity to prevent respiratory disease secondary to obesity. Objectives - To examine the effect of aerobic training on RM strength in overweight and obese individuals. Method - Overweight and obese adults were randomized into experimental(EXP: n = 20) and control(CON: n = 20) groups. Anthropometric measurements, inspiratory & expiratory muscle strength, and estimated oxygen consumption(VO2) were assessed pre and post 8-weeks of aerobic exercise intervention. Experimental group performed a moderate intensity(Borg's RPE= 11 -13) supervised exercise training program 5 days/ week for 8 weeks with a passive Control group. Results - Along with weight reduction(P < 0.05), Inspiratory and expiratory muscle strength significantly improved in EXP Group(MIP = 26.79 % gain, MEP = 16.87% gain;P
