Purpose of the Research: The determination of the present research was to find out the influence of yoga exercise on balance and flexibility among male geriatric population. Materials and Methods: 30 elderly men who lived in the Anbagam Old Age Home, Mariappanagar, Annamalainagar Town, Chidambaram City, Tamilnadu were selected as subjects. The oldness of the subjects was ranged between 60 and 65 years.

Balance was measured by 4 stage balance test and flexibility was assessed by sit and reach test. Statistical Techniques Applied: The examination of ‘t’ – test and assumption of equality of variance (Leven’s test-homogeneity) and analysis of covariance (ANCOVA) was utilized to discover the critical contrast, assuming any, between groups on each selected variable, independently. In all the cases, 0.05 degree of certainty was fixed to test the importance, which was considered as proper. Results: The result of the study shows that the selected yoga practice has improve the balance and flexibility significantly. Conclusions: It was concluded from the consequences of the study that experimental group has bring positive changes in balance and flexibility as compare to the control group.
