Abstract: 本研究的主要目的是以測力板分析獲得原地垂直跳時的重心位置、速度和加速度為效標,計算影片分析法中不同人體肢段參數獲得的人體重心位置、速度和加速度的整體誤差值。實驗以Kistler測力板分析系統(600Hz)收集、計算國內健康大專男生18名(22.8 ± 3.5歲、173.5 ± 5.2公分、67.9 ± 5.5 公斤)進行原地垂直跳時的重心運動學參數變化,並同步以Peak Performance影片分析系統(120Hz)記錄動作過程,通過影片分析法輸入不同人體肢段參數,以計算原地垂直跳時的重心運動學參數,再與測力板過程的運動學參數比較其誤差的大小。影片分析使用的人體肢段參數包括:Dempster屍體法、Clauser迴歸公式法、Zatizorsky & Seluyanov的γ-射線法、胡德貴的電腦斷層掃描法、Hanavan模型法、Matsui的數學模型法和王金成的數學模型法。研究結果顯示垂直跳動作的用力階段重心位移、速度和加速度平均估計標準誤差分別為0.029 ± 0.009m、0.164 ± 0.040m/s、2.369 ± 0.527m/s2;騰空階段重心位移、速度和加速度平均誤差分別為0.041 ± 0.016m、0.187 ± 0.061m/s、0.897 ± 0.263m/s2。而通過Zatziorsky & Seluyanov的γ-射線法、胡德貴的電腦斷層掃描法和Hanavan模型法獲得的人體肢段參數,對於本研究動作描述動心運動學參數的誤差明顯小於其他的肢段參數(p<.05)。本研究的結果將可提供給國內生物力學研究者作為選擇不同人體肢段參數的動態性誤差範圍參考,而本研究開發的方法對於人體測量學的研究與誤差的探究上不僅是一個頗具創意的手段,也是誤差偵測在方法學上的重要突破。
The purpose of this study is to use the displacement, velocity, and acceleration of body center of mass when performing the standing vertical jump from the force plate as a criterion to compare the errors of videotape when using different body segment parameters. Eighteen healthy male academics were served as the subjects for this study. A Kistler force plate (600Hz) and a Peak Performance high speed camera (120Hz) were synchro-nized to collect the subject performing the standing vertical jump. The vertical ground reaction forces and subject mass were used to calculate kinematical variables for the body center of mass during the vertical jumping. It was used as a criterion to compare the results of the body center of mss calculated from the videotape by using different methods of body segment parameters. Those methods including Dempster, Clauser, Zatziorsky & Seluyanov, Hu, Hanavan, Matsui, and Wang studies. The results showed the average standard error of estimate for displacement, velocity, and acceleration during action phase were 0.029 � 0.009m, 0.164 � 0.040m/s, 2.369 � 0.527m/s2 respectively. During the flight phase, the average standard error of estimate for displacement, velocity, and acceleration were 0.041 � 0.016m, 0.187 � 0.061m/s, 0.897 � 0.263m/s2 respectively. This study also indicated the error of kinematical variables in the body center of mass by Zatziorsky & Seluyanov, Hu, and Hanavan model were lower significantly than the other body segment parameters.The purpose of this study is to use the displacement, velocity, and acceleration of body center of mass when performing the standing vertical jump from the force plate as a criterion to compare the errors of videotape when using different body segment parameters.
