The present study aims to assess the impact of yoga practices on selected physiological indicators in school kids. There were expected to be substantial variations in physiological variables due to yogic exercises' influence on physiological variables in Shimla residential school boys. The present study recruited 48 boys from S.V.M. School, Vikas Nagar, Kasumpti, Shimla, Himachal Pradesh. A random sample strategy was utilized to acquire data. The present study employed a pre-test and post-test chosen group comprising a control and an experimental group. Data were obtained before and after eight weeks of training. The variables undertaken in the study were systolic blood pressure, diastolic blood pressure, pulse rate, vital capacity and forced capacity. The data were examined using the dependent t-test. The criterion of significance was fixed at p<0.05. There exists a significant difference in the diastolic blood pressure and pulse rate. And the other side exists no significant difference in systolic blood pressure, vital capacity and forced vital capacity. The study found that diastolic blood pressure and pulse rate dramatically enhanced due to the impact of eight weeks of yoga exercises. Still, the systolic blood pressure, vital capacity and forced vital capacity were significantly enhanced due to the effects eight-week but the enhanced level is low, that’s why the result is not significant for yoga exercises in Shimla's residential school boys.
