Changes in movement parameters under various load conditions during breaststroke swimming were assessed in Coronary Artery Disease (CAD) patients. Kinematic analysis of time-discrete and time-continuous characteristics, and timing of the swim-movement was made during a breaststroke "load-steptest" in a flume for 26 male CAD-patients. Factor analysis was applied. The path of hands, feet and hips, the pause between propulsive phases and the angle of attack of hip-shoulder-water surface are of crucial importance in patients with CAD. These findings are supported by the factor analysis where comparable parameters were found to be of relevance. Results did indicate large individual variations in time-continues characteristics.
