A PILOT STUDY ON COMPARSION OF KINEMATICS CHANGE OF LOWER EXTREMITY WITH DIFFERENET TENNIS SHOES DURING LANDING

Abstract

A study reported that the rate of getting ankle injury was 4.3 times higher among the basketball players who worn shoes with air cells in the heel than those worn shoes without air cells (McKay et aI., 2001). It was hypothesized that the higher rate of ankle injury was due to the air cells located in the heel decreased the rearfoot stability. In tennis, air cells technology also have been applied on tennis shoe construction. However, the kinematics change of the foot has not been reviewed on the tennis shoes with air cells in the heel. The purpose of this paper was to compare the kinematics change of the foot, especially the inversion of the foot, with different tennis shoes during the landing of the lateral jump movement.
