3分鐘26回／分登階測試推估最大攝氧量公式之探討

本研究旨在探討由國小女童進行3分鐘26回／分登階測試後之生理指標推估最大攝氧量公式，以10-12歲國小女童37位為受試者，身高為144.74±7.0公分，體重為40.38±8.80公斤。所有受試者隨機分為兩組，每組均完成最大攝氧量和3分鐘的26回／分登階測試之攝氧量測試，登階高度為受試者身高乘以0.187，每組測試至少間隔48小時。37位受試者利用多元逐步迴歸分析，以最大攝氧量作為自變項，而身高、體重、年龄、3分鐘26回／分登階測試後5秒到20秒心跳(R1)、1分到1分30秒心跳(R2)、2分到2分30秒心跳(R3)和3分到3分30秒(R4)的心跳作為依變項，建立估計最大攝氧量的迴歸公式。再者，以單位體重攝氧量作為自變項時，以身高、R1、R2、R3和R4作為依變項，建立估計單位體重攝氧量的迴歸公式。結果得到公式，最大攝氧量了12.922×體重（公斤）＋17.464×身高（公分）-644.186，其平方值為0.616。單位體重攝氧量=-0.88881×R2+0.82414×R2+55.4844，其平方值為0.2774。由此可知，本研究由3分鐘26回／分登階測試後生理指標來推估最大攝氧量公式或單位體重攝氧量時，其生理反應指標的心跳似不宜。

The purpose of the study was to investigate the predicted formulas of the VO2max form step exercise on female. 37 female subjects whose average height was 144.74±7.0 cm and weight was 40.38±8.80 kg. All subjects randomly divided into two groups, each group completed the maximal oxygen consumption and the oxygen consumption of 26 times/mm step exercise in three mm, between the two measurements take rests two days. Step height was adjusted to the 0.187 for the subject’s height. Multiple stepwise regression was used to analyze the relationship between the VO2max as dependent variable and weigh, height, recovery heart rate 5 ”-20” (R1), 1'-l' 30”(R2), 2'-2'30”(R3), 3'-3'30”(R4) following 3 minute step test as independent variables. The same method was used to analyze the relationship between the oxygen consumption/weigh as dependent variable and height, R1, R2, R3 and R4 following 3 minute step test as independent variables. The VO2max predicted formula is VO2max (L)=12.922×weigh(kg)+ 17.464×height(cm)-644.186(R^2=0.616). The oxygen consumption/weigh predicted formula is Oxygen consumption/weigh (ml/kg/min)=-0.88881×R2+0.824l4×R2+55.4844(R^2=0.2774) When compared with the values of VO2max and oxygen consumption/weigh predicted formulas, VO2max showed that it gave more valid estimates of VO2max than that of oxygen consumption/weigh. Conclusion, the predicted formulas will be not a valid estimates of the VO2max on 10-12 years female.
