Biomechanical analysis in rowing involves consideration of the kinematics and kinetics of the boat-oar-rower mechanical system. The coaching of the rowing stroke has traditionally involved visual analysis of the kinematic parameters which represent the "aesthetics" of the rowing action. Visual analysis of these parameters may not provide sufficient information to accurately quantify or analyze the rowing stroke. A range of kinetic parameters influence these kinematic parameters and overall rowing performance. Kinetic parameters influence the boat, the oar and the rower, however the oar as the main propulsive element, has received the most research attention. Oar force analysis in rowing involves consideration of force-time, oar-angle-time and force-oar angle parameters. Rosing performance depends largely on the magnitude of the force applied to the oar and the angle (or distance) through which that force acts. A plot of this relationship, the force-angle profile, allows examination of biomechanical factors which limit a rower's performance and may assist the coach to recognize the processes involved in the determination of the best available rowing technique for a given rower.
