摘要

本研究係針對女性偶發性的對稱抬舉作業採心物法來決定各種不同高度範圍的最大可承受抬舉重量(MAWL)，並使用受試者的人體測計和肌力變項來建立抬舉能力預測模式。共有12位女性大專學生參與實驗，每位受試者必須執行12種不同的作業，包括六種抬舉範圍(F-K, F-S, F-R, K-S, K-R, S-R)和二種抬舉頻率（一次最大和五分鐘一次）。在模式建立方面，本研究係採多重逐步迴歸技術分別就12種不同的組合逐一決定入選的預測變項並建立4個預測模式，結果以體重、指節高以及等慣性指節高抬舉肌力爲預測變項的整合型的預測模式爲最佳(R^2=0.941, PRESS=147)。此外，若基於設備上的限制，則可以使用另一個以體重、指節高和腰圍爲預測變項的模式作爲作業人員篩選之用(R^2=0.939, PRESS=198)。

This study used the psychophysical approach to determine the maximum acceptable weight of lift (MAWL) of infrequent lifting for 12 young Chinese female subjects, and used strength and anthropometric variables as predictors to develop prediction models. Each subject performed 12 different lifting tasks involving six lifting heights (F-K, F-S, F-R, K-S, K-P, S-R) and two lifting frequencies (one-time-maximum and 0.2 lifts/min). A total of four prediction models were developed by utilizing the stepwise regression technique. The results showed that models developed in this study could predict the MAWLs with a reasonable degree of accuracy. However, a comparison of the models revealed that the integrated model was better than the other models. The predictiors of isoinertial knuckle height strength, body weight and kuckle height were found as the best (P^2=0.941, PRESS=147).
