Aim: To study the difference between barefoot running and running with spikes conditions of sprinters in order to provide information about the potential effects of footwear on competitive runners. Method: The twenty six (n= 26) male sprinters of state/ inter-collegiate level participated and their age range 17 to 25 years were purposively selected as subjects from Haryana State, India. The 100m & 200m. sprint test, acceleration ability by 30m run, stride frequency by high knee action for one minutes, explosive leg strength by standing broad jump and force by using formula (f=ma) were measured in both bare foot and running with spikes running conditions of sprinters. Results: A statistical significant difference was observed for 100m & 200m. sprint test, acceleration ability, stride frequency, explosive leg strength and force in both bare foot and running with spikes running conditions of sprinters. The mean values of 100m sprint, 200m sprint, and acceleration run ability of sprinters run with shoe spikes conditions were found less as compared to sprinters run with barefoot. Hence it clearly indicates that shoe spike sprinters perform better as compared to barefoot running sprinters. Conclusion: It was concluded that shoe spike sprinters perform better for sprint of 100m, 200m, 30m, standing broad jump and force as compared to barefoot running sprinters.
