Abstract: Having tested 5 excellent players by using a sail waving simulator, the author revealed the following findings: As the sail waving time increased, the physical strength of the excellent players would dwindle, but the main indexes for sail waving were reduced gradually, and sail waving became more and more unstable. When train-ing the players by using a sail waving simulator, the coach should emphasize the consciousness of relaxation when returning the sail, and the reduction of the sail returning speed. The problem of the players in China having a weak sail returning technique on the water can be solved by training the players to return the sail at an even speed on the sail waving simulator.
