Abstract (2. Language): 
Yoga is the science practiced in India since ancient times. It is derived from Sanskrit word Yuj means to bind together. Pranayama , a stage of yoga practice, is an ancient science which makes use of voluntary regulation of breathing and calm the mind. The present study was carried out in 60 healthy first year M.B.B.S. students (40 males & 20 females). These students were given Pranayama practice for one hour daily – 6 days in a week for two months. The subjects were assessed for various cardio respiratory parameters like respiratory rate (RR), FVC, FEV1 PEFR, MVV,pulse rate(PR),blood pressure before and after Pranayama practice. Statistical analysis was done by paired T test. There was significant decrease in RR while FVC, FEV1 PEFR, MVV were significantly increased in subjects after the practice of pranayama. There was highly significant increase in 40 mmHg endurance time and significant decrease in pulse rate.
