摘要

Background and Purpose: To investigate test-retest reliability and exercise heart rate of 6-minute walk test (6MWT) and to examine the relationship between 6-minute walk distance (6MWD) and gender, anthropometric variables, and exercise heart rate in healthy preschoolers aged 5-6 years. Methods: Thirty preschoolers were recruited for assessing 6MWT, exercise heart rate, and anthropometry. 6MWT was examined twice. Results: Mean 6MWD was 485.7 ± 42.3 m for boys and was 446.3 ± 40.7 m for girls. Test-retest reliability (intra-class correlation coefficient, ICC), standard error of measurement (SEM), and the smallest detectable difference were 0.82, 19.2, and 53.3 m respectively. 6MWT elicited a moderate exercise response in healthy preschoolers. Heart rate increased rapidly and reached a plateau in the first 1-3 minutes and declined to baseline level within 1-2 minutes after the completion of 6MWT. Height and the difference between baseline heart rate and maximum heart rate was each significantly associated with 6MWD. Conclusions: 6MWT can be reliably administered in healthy preschool boys and girls aged 5-6 years to assess their exercise capacity. Height and the maximum increment in heart rate during the 6MWT were closely associated with 6MWD.

背景與目的：本研究的目的是探討6分鐘行走測試於健康學齡前兒童的再測信度及其心跳反應，以及探討健康學齡前兒童6分鐘行走測試的步行距離與性別、體格、心跳反應的關連性。方法：共收集30位健康學齡前兒童，進行2次6分鐘行走測試，並測量其體格與心跳。結果：學齡前男童6分鐘行走測試的平均步行距離為485.7 ± 42.3公尺，女童則為446.3 ± 40.7公尺。再測信度（組內相關係數）、測量標準誤差、以及最小可偵測之差異則分別為0.82公尺、19.2公尺和53.3公尺。6分鐘行走測試對健康學齡前兒童而言相當於中等程度的運動強度。學齡前兒童之心跳自測試開始就快速地增加，在1 ~ 3分鐘內就達平原期，而心跳在測試結束後1~ 2分鐘內就恢復至基線期的水準。身高以及最大心跳與基線期心跳之差值分別與6分鐘行走測試的步行距離顯著相關。結論：應用6分鐘行走測試於評估5 ~ 6歲典型發展之學齡前男童與女童的運動能力是具有良好信度的。身高及6分鐘行走測試時增加心跳之最大值與6分鐘行走測試的步行距離顯著相關。
