本研究的目的，在利用效度概化的整合分析法，整合以往有關登階測驗評估最大攝氧量的效度研究，以瞭解登階測驗評估最大攝氧量的效度是否達到概化。45個登階測驗評估最大攝氧量的效度研究結果（單一階段與多重階段的登階測驗效度資料各有31個與14個，受試者人數共有2177人次，其中男性受試者共1717人次、女性受試者共460人次），經過效度概化的計算處理之後發現，不管最大攝氧量是以脚踏車測功器、原地跑步機或其他方式測量，登階測驗評估最大攝氧量的效度皆未達到概化。女性爲受試者的登階測驗效度優於男性，青少年爲受試者的單一階段登階測驗效度優於青少年以上年齡者，3分鐘運動時間的單一階段登階測驗效度優於5分鐘的運動時間。登階測驗評估最大攝氧量的方法較適合於青少年與女性，登階測驗的時間則以3分鐘的運動時間較爲有效。登階測驗評估最大攝氧量的真正效度則只在0.7左右。
The validity generalization model was utilized in this study to examine the generalizability of the validity of step test as a measure of the maximal oxygen intake. Forty five studies pertained to the validity of step test as a measure of the maximal oxygen intake had been reviewed, among which one-stage step test was utilized in 31 studies whereas multi-stage step test was utilized in the others. Among the 2177 participants reviewed, 1717 were males and 460 were females. The findings were indicated as follow:(1)the validity of step test as a measure of the maximal oxygen intake, that be measured on ergometer, tradmill or the others, was not found generalizable; (2)the validity of step test was more generalizable for women than for men; (3)the validity of one-stage step test was more generalizable for youth than other ages; and(4)the validity of one-stage step test was more generalizable for 3 min testing time frame than 5-min.In condusion, step test as a measure of the maximal oxygen intake is more appropriate for female and youth, further more, the 3 min testing time frame is more valid than the 5 min.
