Physical inactivity and low cardio-respiratory 􀃶tness are recognized as important causes of morbidity and
mortality. Pulmonary function tests help in monitoring the efficacy of physical training. It includes parameters like
FEV1, FVC, MVV, PEFR, FEF 25-75. Cardio-pulmonary efficiency tests help to study aerobic conditioning, which includes lung ventilation.
Lung ventilation, the most important parameter of physical 􀃶tness is controlled by skeletal muscle 􀃶tness. There are many studies carried
out on defense personals, but very studies about young adults who aspire to take entry in the army, navy or police force. The present study
was aimed to evaluate the importance of physical activity in improving strength and endurance of respiratory muscles. So we measured
various spirometry parameters (PFT) to 􀃶nd out the cardio-respiratory response and blood pressure to study cardio-vascular response in
the individuals who underwent rigorous physical training for 9 months. 30 healthy male subjects between age group of 18-23 years were
selected randomly. Before and after training period of 9 months, spirometry and other parameters like height, weight, body surface area
were recorded. We got statistically signi􀃶cant improvement in parameters like FEV1, FVC, MVV, PEFR and FEF 25-75. We observed
statistically signi􀃶cant reduction in the mean systolic and diastolic resting blood pressure after training. From our results we conclude that
physical training like regular aerobic exercise improves lung function parameters and cardiac efficiency. Regular aerobic exercise improves
cardio-respiratory 􀃶tness.
