Research Abstract

The purpose of this investigation was suggestion of advanced start skill in competitive swimming. It was proposed that the posture on the starting platform with the back plate was more inclining forward than that on the flat platform as results of kinematically and kinetically examining. Because horizontal thrust of a rear leg was large in the backing plate condition、 it was shown that the back plate was suitable for horizontal acceleration. The time constant (TC) of the direction conversion after the entry was about 0.3 seconds. It was positive relation between TC and an amount of the horizontal speed decrease. Therefore、 it was proposed that large horizontal speed and shallow and straight entry control the velocity loss.
