背景與目的：健康體適能與爬樓梯表現之相關性並不清楚。本研究探用健康體適能檢測評估爬樓梯參賽者，分析成人健康體適能所測的每個項目與爬樓梯成績之相關性。方法：有發炎或未控制之全身性疾病而影響爬樓梯是參賽者的排除條件，149位符合條件的臺大醫院員工（66位男性與83位女性），平均年齡38.7±9.1歲，參加爬15層樓（共366階）之爬樓梯競賽。受試者在賽前接受健康體適能測試，內容包含修正式哈佛登階測試(modified Harvard step test, HST)；握力；身體質量指數；腰臀比及軀幹柔軟度之測量。利用爬樓梯競賽成績完成的層樓登階的時間。皮爾森相關係數分析健康體適能所測的不同項目與爬樓梯表現之相關性。結果：依年齡與性別調整後的相關係數，發現登階心肺耐力指數；身體質量指數；腰臀比與爬樓梯時間有明顯相關(γ=0.3-0.36, p<0.001)。爬樓梯時間與軀幹柔軟度呈負相關(γ=-0.18, p<0.05)，但其相關係數很低。上肢肌力與爬樓梯表現則無明顯相關。結論：健康體適能的心肺耐力及體組成評估，與爬樓梯的表現有相關，然而，爬樓梯訓練也可作為加強運動改善心肺耐力及體組成之方式。

Background and Purposes: The relationship between health-related physical fitness (HRPF) and 15-floor stair-climbing performance is not clear. In this study, the subjects received HRPF assessment before a 15-floor stair-climbing contest. The correlation between the components of HRPF and stair-climbing performance in healthy adults were analyzed. Methods: One hundred forty-nine qualified subjects (66 males and 83 females) with mean age of 38.7±9.1 years working at the National Taiwan University Hospital participated in the 15-floor stair-climbing competition (total 366 steps). The HRPF including physical fitness index (PFI), grip strength, body mass index (BMI), waist-hip ratio (WHR) and trunk flexibility were assessed before the competition. The exclusion criteria were with inflammatory or uncontrolled systemic disease that affected the stairs-climbing. The Pearson correlation analysis was performed to examine the relationship between HRPF and stair-climbing time. Results: After the adjustment of age and gender, we found that the correlation of PFI, BMI and WHR with the stair-climbing time (γ=0.30-0.36, p<0.001) was significant. The trunk flexibility was also negatively correlated (γ=-0.18, p<0.05) with stair-climbing time. However, the grip strength was not correlated with the stair-climbing performance. Conclusions: The cardiopulmonary endurance and body composition are correlated with the performance of stair-climbing. The cardiopulmonary exercises are suggested for the improvement of stair-climbing performance, and on the other hand, stair-climbing can also be a kind of activity to improve cardiopulmonary endurance and body com position.
