本研究透過健康體適能的測量，了解至大坑登山步道活動民眾健康體適能情況，並比較不同健康體適能評估等級民眾血脂肪及登山步道活動前，後脈搏和血壓反應的差異。 本研究對象係利用假日至大坑風景區2號登山步道之遊客，且自願全程接受本研究測量流程者。共754名，年齡42.29±8.24歲，男受試者372名，年齡41.47±5.66歲；女受試者382名，年齡43.24±9.77歲。 本研究結果顯示受試者身體質量指數男、女受試者分別為22.93±3.0、21.62±2.61；肱三頭肌皮脂厚(mm)男、女受試者分別為26.32±7.00、19.47±3.04；優勢手握力(公斤)男、女受試者分別為47.07±7.52、27.13±8.53；60秒腹肌耐力(次)男、女受試者分別為27.92±6.12、19.02±4.45；柔軟度(公分)男、女試者分別為4.35±7.59、5.98±8.42．體力指數男、女受試者分別54.13±5.81、56.64±6.45。 經電腦輔助健康體適能評估系統評量結果顯示本次受試民眾評估等級”劣”者佔9.0，”差”者佔25.0，”可”者占26.0%, “良”者占35.0%，”優”者佔5.0%。 不同健康體適能評估等級受試者登山步道活動前安靜脈搏數、舒張壓無顯著差異。登山步道活動前受試者健康體適能評個等級”劣”者安靜收縮壓明顯偏高(p<0.05)。 不同健康體適能評估等級受試者在登步道第一站(第一陡峭坡道終點)活動後脈搏，結果顯示健康體適能評估等級”劣”、”差”者明顯高於健康體適能評估等級”良”、”優”者(p=0.05)；就登至第一陡峭坡道處活動後收縮壓而言，受試者健康體適能評估等級”劣”、”差”、”可”者收縮壓明顯高於健康體適能評估等級”良”、”優”者(p<0.05)，而運動後舒張壓則無顯著差異。 不同健康體適能評估等級受試者健康體適能評估等級”良、”優”者安靜禁食血膽固醇、三酸甘油脂明顯低於健康體適能評估等級”劣”、”差”者(p,0.01)。 研究結果顯示受試者健康體適能評估等級屬”劣”者登山步道活動(第一陡峭坡道終點站處)後收縮壓和安靜時收縮壓比較，有顯著性差異(P<0.05)。研究結果將應用於臺中市政府大坑風景區管理站，設立告示牌：經中臺醫護技術學院保健隊測量健康體適能等級屬”劣”者民眾，不建議登2號步道，或登2號步道過程應參考設立於步道上”2號登山步道陡峭處登山建議”標語牌。

The purpose of this study were: (1) to understand the health-related physical fitness of residents in the Ta-keng hiking trails scenic area, and(2) to compare to fasting, resting serum lipid and blood pressure, pulse among subjects of different health-related physical fitness classifications before and after trail-hiking. There are 754 subjects, whose mean age is 42.29±8.24 years old. The number of male subjects is 372, whose mean age is 41.47±5.66 years old. Female subjects number 382, whose mean age is 43.24±9.77 years old. The subjects have these average measurements: (1) The mean BMI of male and female subjects is 22.93±3.20 and 21.62±2.61 respectively. (2) The mean tricep skinfold value of male and female subjects is 26.32±7.00 mm and 19.47±3.04 mm respectively. (3) The mean muscle strength of male and female subjects is 47.07±7.52Kg and 27.13±8.53 Kg respectively. (4) The mean muscle endurance of male and female subjects is 27.92±6.12 times and 19.02±4.45 times per minute respectively. (5) The mean flexibility of male and female subjects is 4.36±7.59 cm and 5.98±8.42 cm respectively. (6) the mean PI value of male and female subjects is 54.13±5.81 and 56.64±6.45 respectively. The health-related physical fitness of the subjects was calculated with the assistance of the computer system; CAI Assessment Program on Health-Related Physical Fitness. The subjects health-related physical fitness are classified as (1) excellent, 5.0% (2) good, 35.0% (3) acceptable, 26.0% (4) fair, 25.0% and (50 poor, 9.0%. The result in table 4 show that before taking the trail, those who have different health-related physical fitness classifications have no significant different in resting pulse and diatonic blood pressure. However, those subjects whose health-related physical fitness is classified as “poor” have significantly higher values of systolic blood pressure (p<0.05) than those in other classifications. After taking the trail, there significantly faster pulses in groups whose health-related physical fitness were classified as “poor” or “fair” than those in the “excellent” and “good” groups(p<0.05); there were significantly higher values of systolic blood pressure in groups whose health-related physical fitness were classified as “poor”, “fair”, or “acceptable” than in the other classifications(p<0.05); there were no significant differences in diatonic blood pressure in the five groups after taking the trail. The result in table 5 show those subjects whose health-related physical fitness were classified as “excellent” or “good” have significantly lower levels of resting and fasting blood cholesterol, triglyceride than those subjects whose health-related physical fitness are classified as “poor” or “fair”. Results show that those whose health-related physical fitness was classified as “poor” have significantly increase systolic blood pressure (p<0.05) after taking the trail. According to these results the Taichung Civic Center will establish a trail-hikers’ bulletin board recommending trail-takers whose health-related physical fitness is classified as “poor”, take trail number 2 carefully or avoid choosing trail number 2 due to the danger presented by significantly increased systolic blood pressure.
