登山杖之主客觀操作績效評估—以男性大學生為例
The Alpenstock Operability Performance Assessment-A Case Study of Male College Student
摘要
本研究係運用無線生理系統及多功能量測儀，受測者在不同登山方式（未用拐杖、握持一字杖、握持T字杖）、身體負重（0%、10%、20%）、坡度（0%、6%、12%）情形下進行動態實驗，分析心跳率、軀幹角度及肌肉活動度的變化，再以主觀評比（問卷調查）及客觀評比（心跳率、軀幹角度、肌肉活動度）評估操作績效。在主觀評比中，實驗前大部分受試者認為無使用登山杖較舒適及省力；實驗後則認為，未用登山杖在無負重且較平緩坡度（0%、6%）較為省力；當負重上升、坡度上升後，受試者則認為T字杖較為省力。客觀評比中，心跳率會因坡度及負重上升而升高，肌肉活動度及軀幹角度則受肌肉輪替影響而變化；結果顯示，T字杖較適用於平緩地形，一字杖較適用於陡峭地形。

This study is designed to perform dynamic experiments and analyze heart beat rate, trunk angle, and the changes of muscle activities utilizing the wireless physiological system and multi-function measuring instrument. The major influence factors measured in the study include climbing methods (unused alpenstock, held I-head alpenstock, held T-head alpenstock), weight-bearing (0%, 10%, 20%), and slope (0%, 6%, 12%).Based on the objective assessment and subjective assessment, the analysis ofvariations of heart rate, trunk angle, and muscle activity are conducted to assess of their operability. In the objective assessment by survey, most of the participants consider it more comfortable and labor-saving without using alpenstock before the experiment. Results after the experiment showed more labor-saving under the condition of non-weight-bearing and gentle slope (0%, 6%) without the help of alpenstock. However, the increasing weight-bearing and slope rate made the T-head alpenstock more labor-saving. In the subjective assessment, heart beat rate is increasing with slope and weight-bearing rise. Muscle activity and trunk angle are significantly affected by the changes of the muscle rotation. The results show that T-head alpenstock is suitable for flat terrain and I-head alpenstock is superior to steep terrain.
