中文摘要 | 本研究旨在探討3種行李箱拉桿長比(拉桿長與身高比值分別為0.5、0.6及0.7)及3種拉桿握柄夾角(分別為0度、30度及60度)共九種組合下,對於拖行行李箱後受試者的握力差異、絆腳次數、翻箱次數、拖曳總時間以及實驗前/後主觀施力知覺評比差異的效應。十位華梵大學男性學生參與實驗,本研究採完全隨機集區他設計,自變項包括受試者、行李箱拉桿長比以及拉桿握柄夾角,其中受試者視為集區效應。握力差異、絆腳次數、翻箱次數、拖曳總時間以及實驗前/後主觀施力知覺評比差異等變數為本研究之應變項。研究結果顯示拉桿長比顯著影響絆腳次數、翻箱次數及拖曳總時間,0.5拉桿長比的絆腳與翻箱次數顯著多於0.6與0.7拉桿長比;拖曳總時間仍是0.5為最長。握柄夾角則對於上臂ΔRPE及全身ΔRPE有顯著效應,尤其,握柄夾角為30度時,上臂ΔRPE及全身ΔRPE顯著小於60度,顯示60度之握柄夾角於實驗後造成不適程度明顯較嚴重。主客觀各項結果顯示:0.6以上的拉桿長比與30度之握柄夾角為最佳之行李箱拉桿組合。 |
英文摘要 | This study aimed to evaluate the effect of the length-stature ratio (0.5, 0.6, 0.7) and the grip angle (0。, 30。, 60。) on the performance of transporting luggage by pulling manually. The length-stature ratio is the ratio of the length of carrying handle to stature. The grip angle is the angle between the longitudinal axial of the grip of carrying handle and horizontal line. Ten male subjects were recruited from Huafan University. Every subject had to carry the luggage, weighted 20kg, along the fixed route for 600 meters by pulling manually in each experimental trial. The dependent variables, the decrement in grip strength, number of stumbles, number of turning luggage over, elapsed time, upper arm ΔRPE and whole body ΔRPE, were measured. The results indicated that the length-stature ratio significantly influenced on the performance of transporting luggage, elapsed time, number of stumbles and turning luggage over. The length-stature ratio at 0.5 induced significantly longer elapsed time and greater number of stumbles and turning luggage over than that of at 0.6 and 0.7. The grip angle had significant effect on RPE, upper arm ΔRPE and whole body ΔRPE. The 300 grip angle had significantly smaller upper arm ΔRPE and whole body ΔRPE than that of the 600 grip angle. It indicated that the 600 grip angle leaded to severe discomfort at upper arm and whole body after carrying the 20-kg luggage for 600 meters. Based on the results, mentioned above, the carry handle of a suitcase with a 0.6 length-stature ratio handle length and a 300 grip angle was recommended. |
