中文摘要 | 運動鞋的功能主要在增加運動表現及減少運動傷害,一般認為避震能力好的運動 鞋能減少運動傷害的發生,能量反彈能力較好的運動鞋能增加運動表現,因此運動鞋的測試 項目多著重於其避震及能量反彈能力。 本研究使用兩種測試方法: ( 1 )材料測試: 以 SATRA 對 5 種專項各 4 個型號共 20 雙新購的運動鞋進行測試,測量參數有撞擊的負加速 度峰值及第一次反彈高度。 ( 2 )人體測試:八位男性受試者,在赤腳及穿著不同運動鞋 的情況下,以步行、慢跑及快跑的運動方式,藉由測力板,測量其足部著地時所受之地面反 作用力;另外,以原地垂直跳方式,測量其跳起的高度。材料測試結果,排球鞋的撞擊負加 速度約為 23g, 明顯較其他運動鞋的 10 ∼ 12g 高,反彈高度則在各運動鞋間並無太大差 異,大約都在 43 ∼ 47 %。人體測試結果,測得的撞擊力峰值及主動力峰值,在赤腳與穿 鞋時並沒有明顯的差異( p >.05 ),但最大負荷率則赤腳明顯比穿鞋時大( p <.05 ) ,各運動鞋間則沒有明顯差異; 而赤腳及穿上運動鞋的垂直跳高度,也無明顯差異( p > .05 )。由結果可知,以最大負荷率來評估運動鞋的避震能力較為恰當。雖然經由統計分析 ,材料測試與人體測試的結果不盡相同,但趨勢卻是一致,且兩種測試各有其適用的時機: 材料測試能快速反應出鞋底的力學特性且節省時間,因此可使用作為市售運動鞋的功能測試 方法;人體測試雖較費時,且測試結果因人而異,其變異性較大,但較接近真實的人體狀況 ,因此若個人設計專用運動鞋或醫療鞋時,就必須使用人體測試來檢驗鞋子旳功能。 |
英文摘要 | The primary functions of sports shoes are to promote the athletic performance and decrease the occurrence of sports injuries. A shoe with good cushioning ability can prevent the injuries, and one with good energy return ability can enhance the performance. Thus, most of tests for sports shoes focused on the cushioning and energy return ability. Two approaches were applied to test twenty new athletic shoes with various sizes in this study: (1) Material test--SATRA shoe testing instrument was used to measure the deceleration and rebound height of the impact striker, (2) Subject test--eight male subjects were asked to perform different ambulation with barefoot and different footwear conditions. Vertical ground reaction forces were measured using force platform while walking, jogging and sprinting. The heights were measured while the subjects perform the vertical jump. In the material test, the peak decelerations were about 10 ∼ 12 g excluding volleyball shoes (23 g), the rebound heights were about 43 ∼ 47%. In the subject test, the impact force peaks had no significant difference among the six footwear conditions, but the maximum loading rates for barefoot condition were significantly larger than those of other five footwear conditions. Therefore, using the maximum loading rate could better evaluate the cushioning ability of sports shoes compared to the impact force peak. The heights of vertical jump had no significant difference among six footwear conditions. Although the results of statistical analysis in the material and subject tests were not totally agree, they had the same tendency. Furthermore, they can be applied to test shoes in different approaches. Material test can show the mechanical characteristics of the soles quickly and save the testing time, so commercial shoes could be evaluated using the material test. Subject test is time consuming, but similar to real conditions, so a particular shoe designed for individual such as athlete or patient should be evaluated using subject test. |
