摘要

本研究旨在探討登山杖數量、杖柄形狀與坡度對於登山健行者生理成本之影響。共有12位女性受試者參與實驗，每位受試者在負重4公斤背包下，檢定登山杖數量（單杖、雙杖）、杖柄形狀（直柄、T柄）以及坡度（平地、上坡、下坡）對於心搏率（HR）和主觀知覺施力評量（RPE）之效應。為了比較起見，每位受試者均在三種不同的坡度下進行無杖的實驗。結果發現：(1)登山杖數量對於平均心搏率有顯著的效應，以無杖為最高，雙杖為最低；登山杖數量對於整體RPE無顯著效應，但對於腿部RPE有顯著的效應，以單杖為最高，雙杖為最低；(2)杖柄形狀對於平均心搏率、整體RPE及身體各部位RPE均無顯著的效應；(3)坡度對於平均心搏率、整體RPE以及身體各部位RPE均有非常顯著的效應，平均心搏率以上坡為最大，其次為平地，最小為下坡，整體RPE與身體各部位RPE除了腿部外，皆以上坡為最高，其次為平地，下坡為最低，而腿部RPE則以上坡為最高，其次為下坡，平地為最低；(4)整體而言，建議登山健行者在上坡時使用雙杖直柄作為登山輔具；下坡時雙杖直柄或雙杖T柄皆推薦使用；平地則不建議使用登山杖。

This study was investigates the number of trekking poles, pole handle shape and slope of walking surface effects on the physiological costs of mountaineering. A total of 12 female subjects were recruited for these experiments. Carrying a four kilogram backpack, the effects of pole number of poles (the single pole, double poles), pole handle shape (straight handle, T handle) and walking surface slope (flat, uphill and downhill) effects on the heart rate (HR) and the ratings of perceived exertion (RPE) were tested. For the sake of comparison, each subject carried out a without pole experiment of three different slopes. The results showed that: (1) the number of poles had a significant effect on the average heart rate, with no pole the highest and double poles the lowest; (2) the handle shape had no significant effect on the average heart rate, the overall RPE and the body parts RPE; (3) the slope had significant effects on the HR, overall RPE and body parts RPE. The average heart rate uphill was the highest, followed by downhill, with the flat surface the smallest. In addition to the legs RPE, the overall RPE and body parts RPE uphill were the highest, followed by the flat and downhill. The legs RPE for uphill was the highest, followed by downhill, with the flat surface the smallest. It is recommended that mountain hikers use double poles with a straight handle as aids while moving uphill, use double poles with straight or T handle as aids while moving downhill, and use no pole on a flat surface.
