A SIMPLE MATHEMATICAL MODELlNG FOR KINEMATIC, DYNAMIC STUDIES OF SWIM TURN PERFORMANCES

Abstract

A simple mathematical modefing for kinematic and dynamic studies of swim turn performances has been suggested. Side camera was used to obtain timing, hip displacement, velocity and acceleration characteristics of push-off and glide phases in order to justify the proposed modeling. Five elite swimmers were analyzed for a pilot study. It was concluded that this modeling was reliable and useful for feedback to swimmers and coaches on fast and effective turn performances. Water resistance and average leg muscle forces, velocities and accelerations in both push-off and glide phases have been estimated and compared with the results obtained by the other researchers.
