Background: Obesity is known to be a major risk of a whole range of cardiovascular, metabolic and respiratory disorders. In obese individuals, respiratory muscles cannot function efficiently due to increased load on them that they are required to overcome and also due to reduction in their capacity. Respiratory muscle fatigue is a potential mechanism for impaired exercise tolerance. Objective: The study aims to concentrate on finding whether adding Inspiratory muscle training (IMT) to their exercise protocol will be beneficial for overweight and obese individuals. Methods: Overweight and obese individuals were divided into group A (n = 30) and group B (n = 30) groups. BMI, inspiratory muscle strength and oxygen consumption (VO2max) were assessed pre and post-6-weeks of intervention. Group A performed inspiratory muscle training of 3 sets of 10 breathes followed by moderate intensity (Borg__ampersandsignrsquo;s RPE= 11 -13) of walking 20mins for 5 days/ week and progressing to 40mis at the end of 6 weeks. Group B performed only walking for 5 days/week for 6 weeks. Results: Group A showed statistically highly significant improvement in 6 min walk distance (p value=0.0001), PImax (p value= 0.0001) and VO2 max (p value= 0.0035). Thus showing significantly better results in Group A. whereas group B did not show any change post-intervention (p__ampersandsignge;0.05). Conclusion: Individuals who performed IMT along with walking showed greater improvement than the individuals who performed only walking.
