To study effects of regular practice of physical exercise on respiratory functions, respiratory pressures and respiratory endurance 100 healthy volunteers (M68:F32) from age group (17-26) years were included in the study. They practiced some slow walk, calisthenic & stretching exercises daily 1 hour for 3 months. Pulmonary function tests FVC, FEV1, FEV1/FVC, PEFR, FEF25%-75%, RR, TV, MV, MBC or MVV, BR, DI were recorded at start & end of the study. Apart from this MIP, MEP (respiratory pressures), breath holding time (BHT) & 40mmHg endurance test were also recorded. Physical training resulted in improved ventilatory functions in the form of increases in the PEFR, FEF 25-75% and prolongation of breath holding time (BHT) after 3 months of training. Three months Physical training produces a significant improvement in spirometric values. The present data provide more evidence to support the beneficial effect of physical exercise training on respiratory variables in healthy volunteers.
