穿著牛頭牌新式與市售傳統人字拖鞋行走之運動生物力學分析

THE SPORTS BIOMECHANICAL ANALYSIS of WALKING WHEN WEARING BUFFALO NEW STYLE and COMMERCIAL TRADITIONAL FLIP-FLOPS

本研究主要針對穿著牛頭牌新式與市售傳統人字拖鞋行走時的運動生物力學參數進行比較。受詴者為男、女性大專學生各2名。實驗時受詴者分別穿著此兩款拖鞋以最適速度行走各5次，過程中以VICON動作分析系統(含六部M2攝影機，取樣頻率250 Hz)和AMTI測力板(均用右腳踩過，取樣頻率1000)進行資料之擷取。結果顯示牛頭牌新式拖鞋因為前、後削尖設計而導致人體在步態著地期有較小的踝關節運動；另外，牛頭牌新式拖鞋也藉由調整其材質成分比例，使得其避震力表現優於同為EVA材質的市售傳統人字拖鞋。

The purpose of this study was aimed to compare the sports biomechanical parameters when wearing Buffalo new style and commercial traditional flip-flops to walk. Two male and to female college students were recruited as subjects. In experiment， each subject must wear these two kinds of flip-flops to walk five times in its self-selected walking speed. In the process of walking， VICON motion analysis system (including six M2 cameras， sampling rate: 250Hz) and AMTI force plate (when passing force plate， subject must step into using its right foot， sampling rate: 1000Hz) were used to gather data. Results showed: (1) When wearing Buffalo new style flip-flops， human body would have smaller ankle joint motion in landing phase of gait due to Buffalo new style flip-flops had Sharpened design in its toe and heel. (2) By altering the material Composition ratio， Buffalo new style flip-flops performed better on cushion ability than commercial traditional flip-flops which had same EVA material similar to Buffalo new style flip-flops.
