目的：探討大學女學生的800公尺跑走成績與最大攝氧量的相關性，並建立最大攝氧量之迴歸方程式。方法：招募12名自願參加的受試者（年齡：19.8±2.1 yr，身高：160.8±3.9 cm，體重：53.5±5.2 kg，BMI：20.7±1.9 kg/m^2），每位受試者以隨機的順序接受2個實驗處理，包含在田徑場進行800公尺跑走測驗與在實驗室以跑步機進行最大攝氧量測驗，兩個測驗間隔至少7天。所得數據以SPSS19.0統計套裝軟體進行分析，以皮爾森積差相關考驗800公尺跑走成績與最大攝氧量的相關性，並以簡單直線迴歸建立預測方程式。所有數據以平均數±標準差表示，並以p< .05 為達顯著差異。結果：本研究所測得800公尺跑走成績與最大攝氧量的相關為r = -.703（p< .05）。經迴歸建立的預測方程式為最大攝氧量（ml/kg/min）= 76.61- .142 × 800公尺跑走成績（秒），決定係數r^2 =.494，估計標準誤SEE =3.90。結論：本研究數據顯示大學女學生的800公尺跑走成績與最大攝氧量有顯著相關，可利用預測方程式評估最大攝氧量。

Purpose: To investigate the correlation between 800m walk/run and maximal oxygen uptake (VO2max) in university female students, and to establish a prediction equation of VO2max. Methods: Twelve (12) volunteer subjects were recruited (age: 19.8 ± 2.1 yr, height: 160.8 ± 3.9 cm, weight: 53.5 ± 5.2 kg, BMI: 20.7 ± 1.9 kg/m^2), all subjects received two experimental treatments in random order, including 800m walk/run test on the track and the treadmill test for VO2max in the laboratory. Two tests were separated by at least 7 days. The data were analyzed by SPSS 19.0 statistical software. The correlation between 800m walk/run and VO2max were tested by Pearson product-moment correlation, and established the prediction equation by simple regression analysis. All data were showed as mean ± standard deviation, the significance level was set at p< .05. Results: The correlation between 800m walk/run and VO2max was r =- .703(p< .05), and the prediction established by regression equation was VO2max (ml/kg/min) = 76.61 - .142 × 800m walk/run time (second), coefficient of determination r^2 = .494, standard error of estimation was SEE = 3.90. Conclusion: The data in this study indicate university female students 800m walk/run performance was significantly related to VO2max, and the 800m walk/run time can be used for VO2max prediction equation.
