| Objective:Nowadays in China, golf is in a fast developing stage, while the studies of golf are focus on the areas of investments of golf industry and managements of the clubs. There is few study focus on the area of teaching and training. What we can do is translating foreign teaching books, or inviting foreign coaches to train us, this kind of situation is bad for its own development and popularity.Method and Measure:Twenty-one male golfers were performing swings of each club (Driver, Iron4, Iron 7, PW), and the motions were captured by two high-speed cameras. Variables were compared using One-Way ANOVA.Results:Golfers were divided into four groups by Stroke Velocity Index. Maximum angular velocity of club during downswing was significant different between groups, which lead us to the key kinematic pattern of swing, time of downswing.Conclusions:1 The present study establish a new way for estimate the technique level of swing, the SVI way, it can distinguish different levels of golfers efficiently. Its accuracy and applicable range can be improved by further research.2 The time of downswing is the key kinematic pattern of swing, it indicates that low skill golfer can train for shorten the time of downswing to improve swing techniques.3 During the swing, the efficacious ways to shorten the time of downswing are: first, use the relation between backswing time and downswing time, shorten the backswing time will lead to shorten the time of downswing. Second, follow the order of "hip-shoulder-arm-club" kinetic train, what should be noticed is the arm velocity and the release point of wrist. Third, the theoretical analysis of swing indicates that, the improvement of the muscle coordination, the increase of muscle power, and the balance of muscle strength and the flexibility can be useful for shorten the time of downswing. |
