摘要

為探討規律運動與山區活動經驗對健行能力之影響，本研究以54名居住低海拔地區之男女為對象，男女各區分三組，男子規律運動組（N=7）、無規律運動組（N=12）、經常登山組（N=10）；女子規律運動組（N=7）、無規律運動組（N=13）、經常登山組（N=5）；所有受測者皆需在海拔2000至2200公尺（氧濃度17%）環境下接受以下三種測試：一、安靜生理值測試。二、上坡運動測試，需以最快速度完成在坡度21.2度，長250公尺共557階之階梯。三、森林健行測試，以平時在森林步道行走之速度完成。所有測試皆記錄完成時間、運動後及恢復三分鐘後之心跳與血氧飽和度，以觀察規律運動與山區活動經驗是否會影響健行能力，結果如下：一、平地與中等高地安靜與運動時之各項生理值差異：本研究在三分鐘登階後心跳從平地152.87 beats/min增加為中等高地158.88 beats/min，達顯著水準；血氧飽和度由平地97.5%降為中等高地94.13%，達顯著水準；收縮壓中等高地114.25 mm-Hg高於平地109.25 mm-Hg，達顯著水準。二、安靜生理值測試：（一）安靜心跳，男子規律運動組68.57下/分，低於無規律運動組81.08下/分，達顯著水準。（二）最大呼氣流量，男子規律運動組687.14升/秒，高於無規律運動組557.5升/秒，與經常登山組576升/秒，達顯著水準；女子規律運動組455.71升/秒亦高於無規律運動組379.23升/秒，達顯著水準。（三）收縮壓，女子經常登山組100 mm-Hg低於規律運動組115.42 mm-Hg與無規律運動組120.84 mm-Hg，達顯著水準。三、上坡速度測試：（一）上坡運動時間，女子規律運動組352.14秒與經常登山組360秒低於無規律運動組428.69秒，達顯著水準。（二）上坡運動後血氧濃度，女子規律運動組93.91%與經常登山組92.6%高於無規律運動組87.57%，達顯著水準。（三）上坡運動血氧飽和度下降百分比，男子經常登山組2.7%低於規律運動組5.1%與無規律運動組6.2%，達顯著水準；女子規律運動組2.5%與經常登山組3.1%亦低無規律運動組8.7%，達顯著水準。四、森林健行測試：（一）森林健行心跳強度，男子規律運動組55%低於無規律運動組62%，達顯著水準。（二）森林健行後血氧濃度，女子經常登山組95.6%高於無規律運動組93.57%，達顯著水準。由上述結果可知在中等高度之環境，從事最大運動測試與非最大運動測試時，有規律運動習慣與登山經驗者在運動表現與心肺功能上都優於無規律運動者，這兩個因素對健行能力有正面之影響。

The purpose of this study was to investigate regular exercise and mountain-living experience on hiking performance. Fifty four subjects were divided into three group 1) male regular exercise group (n=7), 2) male not regular exercise group (n=12), 3) male frequent mountain hiking group (n=10), 4) female regular exercise group (n=7), 5) female not regular exercise group (n=13) and 6) female frequent mountain hiking group (n=5). All the members were subject to following three tests at altitude around 2000m through 2200m: a) rest testing, b) stair climbing test-complete the 21.2 gradient/557 stairs ASAP, c) mountain trail hiking test-completed a trail at one's usual pace then collected time to finish, heart rate and SaO2 immediately after and 3' after test. Result as followed. Total time to finish stair-climbing test: female regular exercise group-352.14” and frequent mountain hiking group-360” were better than not regular group428.69”. SaO2 after stair climbing: female regular exercise group-93.91 % and frequent mountain hiking group-92.6 % were higher then those of not regular exercise group-87.57 %. The difference of SaO2 after stair-c1imbing: male frequent mountain hiking group-2.7 % was lower than those of regular exercise group-5.1 % and not regular exercise group-6.2 %; female regular exercise group-2.5 % and frequent mountain hiking-3.1 % were lower than those of not regular exercise group-8.7 %. Concerning mountain trail hiking test, relative exercise intensity (% maximum heart rate) of male regular exercise group-55 % was lower than those of not regular exercise group-62 %. The SaO2 after mountain hiking of female frequent mountain hiking group-95.6 % was higher than those of not regular exercise group-93.57 %. We concluded that regular exercise group had better cardiopulmonary function; frequent mountain hiking group had better oxygen uptake efficiency.
