The Comparison Of The Full Swing Between Excellent And Ordinary Golf Players

Purpose:This paper is to make a comparison between excellent golf players and ordinary ones on aspects of swing kinematic characteristics, the dynamic characteristics and the muscle work characteristics. The aim of this paper is to seek the differences between the excellent players and ordinary players on aspects of golf full swing.Methods:Use Qualisys infrared high-speed motion capture system, Mega, myoelectricity acquisition and analysis system and three-dimensional load respectively for excellent and ordinary golfers to test the synchronization in full swing,and use relative software to dispose and analyze original data which have been collected before.Results:1、Stem phase under good golf takes 0.29 ±0.29(s). General golf takes 0.41 ± 0.07(s). Outstanding person’s golf rod under the stage is significantly less than normal(P < 0.01).2、Good golf players’ biggest linear velocity shot moments is 0.012± 0.016(s), and the general ones is 0.069±0.007(s).3、The longest muscle discharge time of ordinary and excellent golf players are the external oblique muscle, and the length were 2.33±0.94(s), 2.40±1.04(s).4、Rod stage on ordinary with excellent golf is on the left side vertical peak, on the right side of the latissimus orsi RMS exist obvious differences(0.01 < P < 0.05).In phase over ordinary with excellent golf is on the left side the latissimus dorsi, there exists significant difference on the left rectus(0.01 < P < 0.05).Conclusion:1、Good golf players’ next bar stage time is shorter, and their swing rhythm control is more reasonable and higher quality.2、Good golf players’ maximum linear velocity moment is closer to the shot, swing in the process of knee joint is more stable, and the quality of swing is higher. Maximum linear velocity of the head moment the closer it gets to the ball, which can be used to evaluate if someone is a good golf players.3、Good golf players have more power to the use of ground reaction force, and the usage of their muscles is more reasonable.4、The sequence of the muscle power is from the external oblique muscle to the back of the upper chest muscles and then return to the waist. Good golf players have longer time to use their waist muscle with greater intensity.
