Many top golfers have limited pronation or hip adduction when their swing is unstable. We suspected these limitations could be the cause of an unstable swing. To clarify this relation, we made a limited model by taping and the swing was analyzed. A professional female golfer, with a stable swing swung a driver. A stick-figure was made. The angular velocity both of the hip and the shoulder, the linear velocity of both of the wrist and the club head during the swing were analyzed by a three-dimensional motion analyzing system. The parameters were compared with those when her pronation or hip adduction was restricted by taping. In a normal swing, the forward swing started in order of the hip, the shoulder and the wrist joint. The maximum velocity appeared in order of the hip, the shoulder and the wrist. The velocity of these joints decreased just before the impact. The club head speed was maximum just at the impact. In the restricted swing, the angular velocity of the shoulder became maximum earlier than that of the hip joint, moreover the angular velocity of the hip joint became faster than that of the shoulder joint. A change in the kinetic chain was seen. In an ideal swing, motion appeared from proximally to distally. The results infer that the limitation of ROM could be a cause of unstable swing and reducing the limitation could improve the swing.
