The aim of this study was to compare the validity of two field tests of aerobic fitness for predicting maximal oxygen uptake (VO2max) in a group of adolescent schoolchildren. Twenty four schoolboys (means age = 15.6 +/- 0.6 yr) and twenty four schoolgirls (means age = 15.4 +/- 0.7 yr) underwent three different tests of aerobic capacity, with one week separating each assessment. The test were: (a) VO2max, using a continuous, progressive treadmill protocol, (b) a physical work capacity test at a heart rate of 170 beats per minute (PWC170), and (c) a 20-metre endurance shuttle run (20-MST), using a modified lapscoring protocol. Heart rates were monitored continuously in all tests. Results (means +/- SD) for boys n = 23) and girls (n = 18) respectively were: VO2max, 53.3 +/- 5.9 and 42.6 +/- 5.8 ml.kg-1.min-1; PWC170, 2.84 +/- 0.47 and 1.86 +/- 0.39 w.kg-1; 20-MST, 81.7 +/- 15.9 and 50.4 +/- 12.5 laps. Linear regression of PWC170 and 20-MST on VO2max scores (n = 41), revealed similarly high powers of prediction for both field tests (PWC170 vs VO2max, r = 0.84; 20-MST vs VO2max, r = 0.87), with an indication that the shuttle run test may be preferable for use with girls. In conclusion, the PWC170 and 20-MST field tests both appear to be valid predictors of VO2max in adolescent schoolchildren. However constraints of time and tester expertise favour the 20-MST for the assessment of aerobic capacity in the field.
本研究的目的是比较两种有氧适能现场测试方法预测一组青春期学童最大摄氧量（VO2max）的有效性。24名男学生（平均年龄 = 15.6 ± 0.6岁）和24名女学生（平均年龄 = 15.4 ± 0.7岁）进行了三项不同的有氧能力测试，每次评估间隔一周。测试项目包括：（a）使用连续渐进式跑步机方案测定VO2max，（b）心率为每分钟170次时的体力工作能力测试（PWC170），以及（c）使用改良的圈数计分方案进行的20米耐力穿梭跑（20-MST）。所有测试均持续监测心率。男生（n = 23）和女生（n = 18）的结果（平均值±标准差）分别为：VO2max为53.3 ± 5.9和42.6 ± 5.8毫升·千克⁻¹·分钟⁻¹；PWC170为2.84 ± 0.47和1.86 ± 0.39瓦·千克⁻¹；20-MST为81.7 ± 15.9和50.4 ± 12.5圈。PWC170和20-MST对VO2max分数（n = 41）的线性回归显示，两种现场测试的预测能力同样高（PWC170与VO2max，r = 0.84；20-MST与VO2max，r = 0.87），表明穿梭跑测试可能更适合女生使用。总之，PWC170和20-MST现场测试似乎都是青春期学童VO2max的有效预测指标。然而，考虑到时间和测试人员专业知识的限制，20-MST更适合用于现场有氧能力评估。
