Background and Aim: Yoga practice may be beneficial for promotion of good health and mental well-being of the children and helps them to adopt with the changing environment. The present study has been designed to find out the effects of 12 weeks of yoga practice on body composition and cardiopulmonary variables of 10–12 years female volunteers. Materials and Methods: Ninety-eight healthy female children volunteers (age 10–12 years) were screened, among them thirty eight were excluded, and the remaining 60 volunteers were randomly divided into: (i) experimental Group (n =30) and (b) control Group (n =30). Yoga practice (60 min/d, 06 d/wk for 12 wks) was followed in the yoga group with no yoga practice in control group. Body composition, heart rate, blood pressure, and pulmonary functions were assessed in both the groups at the beginning (0 week) and after 12 weeks. Results: Significant increase (P < 0.05) in forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), peak expiratory flow rate (PEFR), maximum ventilatory volume (MVV) and breath-holding time (BHT) and; decrease (P < 0.05) in percent body fat, total fat mass, body mass, resting heart rate (RHR), systolic blood pressure (SBP), respiratory rate (RR) were noted following a 12 week yoga practice among the yoga group participants. Further, the yoga group had significantly (P < 0.05) greater FVC, FEV1, MVV, and BHT and decreased fat mass, SBP, RHR, and RR when compared to the control group after 12 weeks of the study. In the control group, no such changes were noticed after 12 weeks of the study. Conclusion: Regular practice of yogic asanas, pranayama, and meditation improves body composition and cardiopulmonary functions of children.
