The paper analyze the movement features specifically from the backswing, swing and follow through these three stages. The results show that Ramos's movement is reasonable. The body's center of gravity descends obviously, and the backswing reveals the mechanics principle that the large joints leads to the small joints. The whipping movement is obvious during the swinging stage, but the body's twist is smaller. During the follow through stage Ramos' stop movement is obvious, but at the end of the moment the legs are still in a state of bending, especially the right knee is still in a lower position, which shows that Ramos didn't stretch hip and knees sufficiently during the follow through stage.
