目的：本研究針對優秀選手使用不同推桿握把尺寸對於握壓影響之探討，並比較優秀選手與初學者之握壓差異。方法：8位大學校隊選手及八位初學業餘人士參與本實驗。透過壓力感測系統，收集使用粗、中等及細推桿握把尺寸下，推桿過程中握壓變化情形。藉3D紅外線動作分析系統，將推桿動作分期。經資料處理後，透過相依樣本t考驗與重覆量數單因子變異數分析的方式進行分析。結果：優秀選手使用3種不同握把推桿，其推桿距離控制度與方向控制度未達顯著差異，而初學者使用細握把推桿時有較佳之方向控制能力。使用不同握把尺寸在推桿過程中，握壓皆在上桿期較弱，下桿期昇高，並在送桿期逐漸降低。結論：建議初學者使用較細之握把，來增加推桿表現之方向控制度。優秀選手與初學者之握壓趨勢是相當雷同的，因此握壓可能不是影響推桿表現的重大要素。未來可針對握把尺寸是否會影響腕關節活動做進一步之探討。

Purpose: The purpose of this study was to explore the effect of golf putter grip size on grip pressure in elite golfers. Methods: Eight expert college golfers and eight novice college golfers were involved in this study. The grip pressure was measured by Pliance-x System Golf sensor-S2035 at 50Hz with the sensor mat rolled on the putter to measure the grip pressure distribution during the putting stroke. The phase of putting stroke was identified from 150-Hz video. Intraclass were compared using dependent t-test and one-way analysis of variance to determine differences in grip pressure and putting performance. Results: There were no significant difference between putting distance and direction control in different putter grip size for elite players, but novice player had better direction control with thin grip than median grip. Expert and novice golfer's grip pressure for different grips did not remain the same throughout the whole stroke, it might be affected by the different phase of stroke and the stroke speed. Conclusion: The research discussed in this paper suggests that novice players should use a thin putting grip to improve direction control. There were similar trend in putting distribution between expert and novice players, therefore, grip pressure may not have a major influence in putting performance. The effect of putting grip size on wrist movement can be discussed in a further study.
