穿著不同鞋釘數高爾夫球鞋揮桿時前腳鞋底摩擦係數比較之探討

THE PRELIMINARY COMPARING STUDY ON FRONT FOOT SOLE’S COEFFICIENTS OF FRICTION WHEN WEARING GOLF SHOES WITH DIFFERENT SPIKES TO SWING.

本研究以球鞋底分別裝設11顆及7顆同款鞋釘及無安裝鞋釘之三款高爾夫球鞋於揮桿時前腳鞋底摩擦係數進行比較，進而初步了解鞋釘對於高爾夫球鞋摩擦係數的影響。以1名男性高爾夫球友為受試者，實驗時受試者需分別穿著上述三雙球鞋使用七號鐵桿進行揮桿擊球，動作過程中則使用VICON動作分析系統（六部M2攝影機，取樣頻率500Hz；1塊AMTI測力板，取樣頻率1000Hz）針對受試者的揮桿動作進行分期並擷取對地作用力數值。EXCEL套裝軟體則用來進行摩擦係數的計算。結果顯示穿著11顆鞋釘球鞋進行揮桿在摩擦係數的表現上有較佳的趨勢，7顆鞋釘球鞋次之，無鞋釘球鞋則較差。

In this study， three golf shoes with 11 spikes， 7 spikes and no spike were used to compare front foot sole’s coefficients of friction (COF) when the subject wearing them. All the spikes on these shoes are the same types. Then， how the spike to effect the COF of golf shoe could be comprehended. One male golf recreational player was recruited as subject. In experiment， the subject should wear these three shoes and using 7 iron to swing respectively. When the subject was acting swing， VICON motion analysis system (six M2 cameras， sampling rate: 500 Hz; one AMTI force plate， sampling rate: 1000 Hz) was used to divide its swing motion into several phases and gather values of force acting to the ground. EXCEL software was used to compute COF. Result showed the performance of COF was better when wearing golf shoe with 11 spikes to swing， the performance of COF was normal.
