A KINEMATIC ANALYSIS TO THE EFFECT OF VELOCITY CHANGES ON THE TREADMILL OF FORWARD MOTION ON THE FEET DISTANCE IN FENCING

Abstract

PURPOSE The purpose of this study was to detect the effect of velocity on the displacement measured as a length between feet through the forward locomotion in fencing and to analyse the kinematics of the legs motion. METHODS six subjects from Jordan National Fencing team were studied in this investigation. Three males and three females were filmed using a Sony Video camera from the sagittal plane during the execution of forward locomotor motion on a treadmill. The speed of the treadmill was controlled and the subjects exposed to three different velocities 3, 7, and 11 km/h. Data were analysed from the screen of Television and were entered into a computer where "SAS" statistical packages was used to analyse the data. RESULTS The results were as follows: 1- There were significant differences for the increment of the velocities on the distance between feet for all subjects.2. There was a negative correlation between the increment of velocity and the distance between the feet. 3. There were a significant faults and mistakes in the kinematics of legs motion such as, forward and backward trunk swing during the forward motion. CONCLUSIONS It was concluded that there were great effect of velocities on the distance between the feet. It is therefore suggested to offer a specific training program to conserve the on-guard position during the forward motion.
