Previous studies have identified differences in selected kinematic and kinetic variables between skilled (SG) and novice (NG) golfers. However no study has examined the unique factors that may differentiate these groups in three particularly critical areas; trunk rotational patterns, weight shift pattern, and the swing path. Thus, the purpose of this study was to examine specific kinematic and kinetic variables associated with these areas during a full-shot golf swing, relative to how they may differ between SG and NG Subjects included thirteen SG (23.94 +/- 3.13 yrs, average handicap = 0.80 +/- 2.55) and seventeen NG (26.31 +/- 4.89 yrs, average handicap = 30.76 +/- 5.54). Kinematic and kinetic data were obtained through high speed 3-D videography and force plates while the subject performed a full shot golf swing with a driver. Multiple trials of each golfer's swing were recorded and averaged for the analysis. Each of the selected variables was compared between the groups at eight selected temporal events using an independent T-test (significance at alpha = .05). The results indicated that critical differences existed between the groups at the back swing, initial phase of the down swing, and follow through. A trunk dominated back swing motion with a faster weight transfer pattern was evident in the SG, while the NG showed an arm dominated back swing motion with a slower weight transfer pattern. The SG initiated the down swing motion from the lower segments of the trunk with a faster weight transfer to the lead leg, while the NG initiated the down swing motion with whole trunk segments. These motion patterns appeared to significantly affect the cocking angle during the down swing. An increased anterior-posterior pelvic tilt, with a greater right-foot VGRF was evident in the SG at the follow through, while the NG showed less anterior-posterior tilting of the pelvis with a smaller right-foot VGRF. This study supported previous research on the golf swing, and provides new insight into the role of the trunk rotation and weight shift pattern in influencing the outcome of the swing.
