JOINT EFFECT OF STRIDE LENGTH AND STRIDE WIDTH ON RUNNING PERFORMANCE

The purpose of this study is to describe joint effect of stride length and stride width on running performance of 100m sprinters and 5000m distance runners during completion. Twenty runners (Ten100m sprinters & Ten 5000m distance) from All India Athletic Meet were selected for the study. The aged ranged from 18 - 25years, height ranged from 1.56 - 1.85 m, body weight rang ed from 49 - 75 kg were of subjects. The subject’s running motion was recorded using two Synchronised video cameras. One was secured to 2m behind 100m starting line for recording stride width and second was secured 18m away from first lane and 50 m from st arting line in filed area for recording the stride length. Softwares MPEG, Photo Studio, SthSDVD , Coral - 5 , Coral ? 9 , Player, and SPSS Software were used to analysed recorded data. F - Test has been applied to know the joint effect of stride length and stride width on running performance timings. The result was found that joint effect of stride length and stride width have significant effect on sprinter’s running while joint effect of stride length and stride width have no significant effect on 5000m lo ng distance running. Statistical significance was set at P< 0.05.
