Method: A Redlake cameras (frequency of 250Hz, the shutter is 1/500sec) take a player by the implementation of the National Taiwan Normal University Bhavsar action of 2D images, and make digital imaging and motion analysis, to understand the impact of the completion of Bhavsar action important factor, as coaches and players during a training reference. Result: 1. Subjects in the implementation of Bhavsar, the highest score move center of gravity vertical speed of in the second position, and shoulder angle extension rate in the fourth position, and ankle joint level speed and center of gravity level speed in the sixth position fast then the lowest score move. 2. Successful group and defeat group movement when center of gravity peak position, the ankle joint level speed reaches the significant difference, other parameters were no significant differences. Conclusion: In second position stress press center of gravity position down to stored the elastic potential energy in muscle, in fifth position, shoulder quickly pulled up, and ankle while stepping down to opposite the direction and overturned of the original formation, the more quick swing the key to success for this action.
