Abstract:
The purpose of the study was to the impact of weighted vest and weighted sled running on stride frequency of sprinters. To achieve the purpose of this study, forty five male sprinters from the Delhi Public school, Bangalore. The age, height and weight of the subjects ranged from 17 to 19 years, 155 to 165 centimeters 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. 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. The experimental groups had significant improvement on stride frequency when comparing to the control group.
