The purpose of the study was to cause of weighted vest and weighted sled running on elastic power of school sprinters. To achieve the purpose of this study, forty five male sprinters from the Public school. The age, height and weight of the subjects ranged from 17 to 19 years, 155 to 165 centimetres and 50 to 55 kilograms in that order. They were divided into three groups; each group consisted of fifteen subjects. Group-I underwent weighted vest sprint training, group-II underwent weight sled training and group-III acted as control who does not participate in any training programme. The data collected from the three groups prior to and post experimentation were statistically analyzed by analysis of covariance (ANCOVA). When the obtained ‘F’ ratio value in the analysis of covariance test was significant, the Scheffe’s test was applied as post hoc test to determine the paired mean differences, if any. In all the cases, statistical significance was fixed at .05 levels. Conclusion: The experimental group sprinters had significant improvement on elastic power when comparing to the control group sprinters.
