3D KINEMATIC COMPARISON BETWEEN ON-WATER AND ON ERGOMETER KAYAKING

Abstract

The purpose of this study is to propose a method for comparing on-water versus on ergometer kayaking. Two elite kayakers were filmed at 84 strokes per minute on an ergometer and in an indoor dock. Linear and angular time histories for the upper limbs were recorded and the kinematics repeatability on the ergometer and between the two environments was measured using a coefficient of multiple correlations (CMC). The kinema tics were, on the whole, repeatable within ergometer cycles and between the on-water and on ergometer environments except for shoulders . The main modifications concerned the motion of both shoulders in the frontal plane, these being explained by the specific resistance of the water and the kayakers' balance on water.
