COMPARISON OF SNOWSHOEING KNIEMATICS ON GRASSLAND AND SAND COURSE – PILOT STUDY

Abstract

The purpose of this study was to compare the kinematics characteristics of snowshoeing on grassland and sand course in elite Hong Kong mentally handicapped athletes. Two athletes were asked to perform the snowshoeing on grassland and sand course with their maximal speed. Kinematics parameters included single leg support time, flight time, stride frequency, velocity of center of gravity (CG), vertical displacement of CG, cycle length, thigh and knee angle were measured. The results of low extremity kinematics supported that there were differences in movement pattern of snowshoeing between grassland and sand course.
