Effect of muscle exhaustion on kinematics of kayak rowing

Abstract

Changes in kinematic structure of stroke movements caused by exhaustion are investigated in the paper. Young oarsmen at the age of 15–16 years having qualification of the first sports category and the candidate for the master of sports took part in the experiment. At passage of a distance of 1000 m on rowing ergometer, a registration of dynamic parameters of every stroke with continuous videorecording has been made. Using obtained videodata, the analysis of stroke movements in various phases of stroke for a number of kinematic pairs has been carried out: oar–water, trunk–vertical, rotation of trunk around vertical axis, trunk–shoulder, shoulder–forearm. Possibility of determination of stroke movements parameters and estimations of change of stroke kinematic characteristics under the influence of exhaustion are shown.
