Development of the Estimate of Computer Assistance Program for Checkmark Position by Different Bend Radius of Curvature of Different Lanes in 4x100m Relay

Abstract

This study aims to discuss the effect of radius of curvature on the checkmark in different lanes of 4×100m relay and offer appropriate suggestion of checkmark according to the speed of different runners. The objects of research were sixteen outstanding players of senior high school and college who had accepted the long-term training in 4×100m relay. The research obtained the interval time of checkmark calculation of each runner in 130m to calculate the interval speed by SPM100. This study found that the forecast formula of bend speed developed by Greene in 1985 could be used in present PU track, thus we applied it to substitute the actual measurement. Experimental checkmark was calculated from the interval speed of incoming runner in last 30m and the starting speed of outgoing runner in 30m. Traditional checkmark was the original used distance. Both of them had the obvious differences (P< .05). Hence, the two checkmarks had different results. Comparing the individual grade, the grades of experimental checkmark were better than the grades of traditional checkmark. Therefore, the estimate of computer assistance program for checkmark position by the different bend radius of curvature of different lanes in 4×100 m relay could be applied to the real competitions which can provide the runners and coaches as prompt references, which expect to reduce the possibility of mistakes of baton exchange and let relay process more easily completed. © Springer International Publishing Switzerland 2014.
