本研究目的旨在比較三分鐘登階測驗後，以走動、站立與靜坐等三種不同恢復方式的結果，並探討心肺耐力指數與3000公尺耐力跑成績的相關。以隨機取樣方式，抽取政戰學校二年級男生60名為受試對象，年齡在19-21歲間。所有受試者以平衡次序法，進行各兩次的三分鐘登階測驗後的走動、站立與靜坐恢復等方式的心跳數測量及3000公尺耐力跑步測驗。兩次測驗結果以平均數做為分析的依據。經SPSS 8.01中文版套裝統計軟體，進行分析，獲得以下的結果：三分鐘登階測驗後走動、站立與靜坐恢復方式所得之心肺耐力指數分別為77.93±8.94, 53.59±11.03 與51.99±10.48；3000公尺耐力跑成績（秒）為867.22±76.06。變異數分析結果顯示，三分鐘登階測驗後走動恢復所得的心肺耐力指數，顯著地低於站立與靜坐恢復方式(P<.01)。三分鐘登階測驗後的走動、站立與靜坐等三種恢復方式之心肺耐力指數均與3000公尺跑步成績無顯著的相關。本研究的結果，顯示三分鐘登階測驗後不同恢復方式影響心肺耐力的評估結果，本研究也顯示三分鐘之登階測驗不宜作為3000公尺跑步的替代項目。作者除建議國人從事三分鐘登階測驗後的恢復期間，應採用規定之恢復方式外，也建議重新評估三分鐘登階測驗對耐力跑的評估能力。

The purposes of this study were to compare the fitness indexes derived from different models, i.e. walking, standing and sitting models, following 3-mm step test and to investigate the relationships between fitness index and 3000-rn running performance. Fitness tests of sixty 19-21 year old healthy college males were measured in balanced order following three different kinds of recovery model following 3-mm step tests. Test and retest were carried out for different step tests and 3000-rn run performance, and mean values were used for statistical analysis (One way ANOVA with repeat measures; SPSS 8.01 Version). Results reveled that: 1) Mean Fitness Index derived from walking, standing and sitting models and 3000-rn run were 77.93 ± 8.94, 83.89 ± 11.03 and 81.99 ± 10.48 and 867.22 ± 76.06 sec respectively. 2) The Fitness Index followed walking model was significantly lower than those of standing and sitting models. 3) Fitness Indexes from three different recovery models were not significantly correlated to 3000 m run performance. The study indicated the needs of definite resting model be applied following 3-min step test and further validation of 3-min step test on cardiovascular fitness evaluation.
