设计了20米穿梭跑极限多段试验，以测定小学生、参加健身课的健康成人和参加频繁起停运动（如篮球、击剑等）的运动员的最大有氧能力。参赛者在20米跑道上来回跑，必须触到20米线；与此同时，声音信号从预先录制好的磁带中发出。声音信号的频率每分钟从8.5公里每小时增加0.5公里。当受试者不再能跟上步伐时，用最后公布的阶段数从该阶段（速度= 8 + 0.5阶段号）对应的速度（X, km h-1）和年龄（A，年）预测最大摄氧量（VO2max） （Y, ml kg-1 min-1）： Y=31.025 + 3.238 X - 3.248A + 0.1536。AX, r = 0.71, 188名8-19岁的男女。为了获得这种回归，测试是单独进行的。终止后立即用4个20 s样品测量VO2，并通过反向外推恢复时间为零的O2恢复曲线估计VO2max。对于成年人，类似的测量表明，同样的方程可以用于保持年龄恒定在18岁（r=0.90, n = 77名18-50岁的男性和女性）。儿童（139名6-16岁的男孩和女孩）的重测信度系数为0.89，成人（81名20-45岁的男女）的重测信度系数为0.95。学龄儿童和成人也有正常数据，估计的VC2max与其他测试和/或人群相当。
A maximal multistage 20 m shuttle run test was designed to determine the maximal aerobic power of schoolchildren, healthy adults attending fitness class and athletes performing in sports with frequent stops and starts (e.g. basketball, fencing and so on). Subjects run back and forth on a 20 m course and must touch the 20 m line; at the same time a sound signal is emitted from a prerecorded tape. Frequency of the sound signals is increased 0.5 km h-1 each minute from a starting speed of 8.5 km h-1. When the subject can no longer follow the pace, the last stage number announced is used to predict maximal oxygen uptake (VO2max) (Y, ml kg-1 min-1) from the speed (X, km h-1) corresponding to that stage (speed = 8 + 0.5 stage no.) and age (A, year): Y=31.025 + 3.238 X - 3.248A + 0.1536.AX, r = 0.71 with 188 boys and girls aged 8-19 years. To obtain this regression, the test was performed individually. Right upon termination VO2 was measured with four 20 s samples and VO2max was estimated by retroextrapolating the O2 recovery curve at time zero of recovery. For adults, similar measurements indicated that the same equation could be used keeping age constant at 18 (r=0.90, n = 77 men and women 18-50 years old). Test-retest reliability coefficients were 0.89 for children (139 boys and girls 6-16 years old) and 0.95 for adults (81 men and women, 20-45 years old). Normal data are also available for schoolchildren and adults and estimated VC2max were found comparable to other tests and/or populations.
