Kinematic Analysis of Short Game Swing Technique of Excellent Female Golfers in China
OBJECTIVE:This study investigates the distinctive characteristics of short game swing techniques in exceptional Chinese female golf players,offering theoretical underpinning for the scientific advancement of golf training programs.METHOD:Employing a three-dimensional high-frame video analysis,we captured and scrutinized the short game swing actions of 12 outstanding Chinese female professional golf players within the rough areas during competitions.RESULTS:(a)The mean values for swing speed(32.42±6.27 km/h)and ball speed(32.23±4.96 km/h)closely aligned.Horizontal flight distance exhibited a positive correlation with swing speed and ball speed(p＜0.05),while launch angle demonstrated a negative correlation with horizontal flight distance(p＜0.05).(b)The alteration in right hip angle during the upswing phase exhibited a positive correlation with horizontal flight distance(p＜0.05).(c)At the upswing apex,hip rotation on the sagittal plane showed negative correlations with launch angle,horizontal flight distance,roll distance,and stance width(p＜0.05).(d)The time taken for the downswing(0.28±0.03s)closely mirrored the follow-through time(0.29±0.09s),with downswing time constituting roughly half of the upswing time(0.68±0.10s).CONCLUSIONS:(a)Similar mean values for swing speed and ball speed suggest that clubhead speed may not be fully translated into ball speed in practical short game scenarios.(b)During the upswing phase,reducing angles in the right shoulder,right elbow,and right wrist proves effective in increasing swing speed and ball speed.Augmenting right hip rotation during this phase effectively enhances horizontal flight distance.(c)Decreasing stance width aids in diminishing upward center of gravity movement during the upswing,subsequently elevating launch angle.
