The purpose of this study was to develop a submaximal, 1.5-mile endurance test for college-aged students using walking, jogging, or running exercise. College students (N = 101: 52 men, 47 women), ages 18-26years, successfully completed the 1.5-mile test twice, and a maximal graded exercise test. Participants were instructed to achieve a "somewhat hard" exercise intensity (rating of perceived exertion = 13) and maintain a steady pace throughout each 1.5-mile test. Multiple linear regression generated the following prediction equation: VO2 max = 65.404 + 7.707 x gender (1 = male; 0 =female) - 0.159 x body mass (kg) - 0.843 x elapsed exercise time (min; walking, jogging orrunning). This equation shows acceptable validity (R = .86, SEE = 3.37 ml x kg(-1) min(-1)) similar to the accuracy of comparable field tests, and reliability (ICC = .93) is also comparable to similar models. The statistical shrinkage is minimal (R(press) = 0.85, SEE(press) = 3.51 ml x kg(-) x min(-1)); hence, it should provide comparable results when applied to other similar samples. A regression model (R =.90, and SEE = 2.87 ml x kg(-1) min(-1)) including exercise heart rate was also developed: VO2 max = 100.162 +/- 7.301 x gender(1 = male; 0 =female) - 0.164 x body mass (kg) - 1.273 x elapsed exercise time -0.156 x exercise heart rate, for those who have access to electronic heart rate monitors. This submaximal 1.5-mile test accurately predicts maximal oxygen uptake (VO2max) without measuring heart rate and is similar to the 1.5-mile run in that it allowsfor mass testing and requires only a flat, measured distance and a stopwatch. Further, it can accommodate a wide range of fitness levels (from walkers to runners).
本研究的目的是为大学生开发一种次最大强度的1.5英里耐力测试，采用步行、慢跑或跑步运动。18至26岁的大学生（N = 101：52名男性，47名女性）成功完成了两次1.5英里测试以及一次最大分级运动测试。参与者被要求达到“有点费力”的运动强度（主观用力程度评级 = 13），并在每次1.5英里测试中保持稳定的速度。多元线性回归得出以下预测方程：最大摄氧量 = 65.404 + 7.707×性别（1 = 男性；0 = 女性） - 0.159×体重（kg） - 0.843×运动时间（分钟；步行、慢跑或跑步）。该方程显示出可接受的有效性（R = 0.86，标准误 = 3.37 ml×kg⁻¹×min⁻¹），与类似现场测试的准确性相似，并且可靠性（组内相关系数 = 0.93）也与类似模型相当。统计收缩最小（交叉验证R = 0.85，交叉验证标准误 = 3.51 ml×kg⁻¹×min⁻¹）；因此，当应用于其他类似样本时，它应该能提供可比的结果。还开发了一个包含运动心率的回归模型（R = 0.90，标准误 = 2.87 ml×kg⁻¹×min⁻¹）：对于可以使用电子心率监测器的人，最大摄氧量 = 100.162 ± 7.301×性别（1 = 男性；0 = 女性） - 0.164×体重（kg） - 1.273×运动时间 - 0.156×运动心率。这种次最大强度的1.5英里测试无需测量心率就能准确预测最大摄氧量（VO₂max），并且与1.5英里跑类似，它允许进行大规模测试，只需要一个平坦的、测量好的距离和一个秒表。此外，它可以适应广泛的健身水平（从步行者到跑步者）。
