- 中文摘要: 本研究探討當受試人員以心物法決定最大可受之抬舉重量時,所產生的人體反應關聯模式。研究分別就偶發性、持續性、與短暫性的抬舉作業建立各個工作負荷值(抬舉重量與頻率)與同步收集之肢體受力值(髖關節力矩與足底反作用力)、生理反應值(心跳率與耗氧量)、及心理反應值(主觀心理評價)間之假設模式。徑路分析之結果驗證了各模式之合宜性,並顯示如欲運用心物法決定一次可抬舉之最大可接受之重量時,將無法有效的整合肢體受力的反應;在進行每分鐘四次及六次之抬舉作業時,最大可接受之抬舉重量取決於受是人員之生理反應值;在進行每分鐘一次之抬舉作業時,肢體受力值是影響由心物法決定最大可接受之抬舉重量的支要因子。透過人體反應關聯模式之建立,研究結果提供了在不同抬舉頻率下,決定抬舉能力之人因工程途徑。
- 英文摘要: This research attempted to study the relationship between the lifting workload and the respondingbehaviors of the multiple stress while individuals used the psychophysical approach to determine themaximum acceptable weight of lift. The structural equation models of different lifting frequencies weredesigned to decompose relations among the lifting workload and the associated biomechanical(hip jointmoments and ground reaction forces), physiological (heart rate and oxygen consumption), and psychophysical(rate of perceived exertion) responses. The path analysis showed that the one time maximum liftingworkload might not be a good indicator of the psychophysical responses. For a lifting task of 4 lifts/min and 6 lifts/min, the MAWL appeared to depend upon the degree to which individuals evaluated thephysiological stresses imposed by the lifting workload. Task specific biomechanical responses areimportant individual variables affecting the interpretation of the relationship between the MAWL of llift/min and the psychophysical responses.
