An oar blade behaves as unsteady hydrofoil and its load strongly depends on a reduced frequency of the rowing motion. The tank lest is carried out using a circulating water channel to estimate the load. Computational Fluid Dynamics (CFD) Simulation of a rotating flat plate in uniform flow, which corresponds to the tank lest in circulating water channel, reveals transient phenomena of flow field around the plate and explains the reason why the normal force coefficients strongly depend on the reduced frequency. The program which simulates the rowing motion of a single scull is developed. The force that pulls the oar handle and the motion of the rower's centre of mass are input values for the simulation. The input values represent the rower's performance, that is, the rower's power and body movements. The results of the simulation are in good agreement with the in-situ experiments, and the method can be used as a VPP (Velocity Prediction Program).
