Four subjects were investigated with velocity of 25 and 15 km/h of 20 trials of the same three positions on a flat floor 50-m long in sports hall. The velocity-time function was measured by a tachogenerator mounted with a telemetry bicycle. Least squares method was used to estimate the Cd value. The results showed that the mean of Cd for DP and AP less than UP.
