The aim of this study was to assess the validity of a 20 metre multi-stage shuttle run (20-MST) as both a field test of cardiorespiratory endurance and as a predictor of competitive performance in a 10 kilometre (10 km) race. Nine male subjects (age 35.4 +/- 5.8 years) (mean +/- SD) underwent a laboratory test of maximum oxygen uptake on a treadmill (VO2 max 59.0 +/- 9.9 ml.kg.-1min-1), completed the 20-MST (score 105 +/- 23.7 laps/11.4 +/- 2.7 paliers) and competed in a 10 km race (finishing time 41.8 +/- 7.3 minutes). Analysis using Pearson's Product Moment Coefficient revealed high correlations between these variables (20-MST vs. VO2 max, r = 0.93; 20-MST vs. 10 km, r = -0.93; VO2 max vs. 10 km, r = -0.95). These results confirm that the 20-MST is a valid field test of cardio-respiratory endurance and suggest that it can additionally be used to predict relative running performance over 10 km.
本研究的目的是评估20米多级往返跑(20-MST)作为心肺耐力的现场测试以及10公里(10 km)比赛竞技表现预测指标的有效性。九名男性受试者(年龄35.4±5.8岁)(平均值±标准差)在跑步机上进行了最大摄氧量的实验室测试(最大摄氧量59.0±9.9毫升·千克⁻¹·分钟⁻¹),完成了20-MST测试(成绩为105±23.7圈/11.4±2.7级),并参加了10公里比赛(完赛时间41.8±7.3分钟)。使用皮尔逊积矩系数进行分析发现,这些变量之间存在高度相关性(20-MST与最大摄氧量,r = 0.93;20-MST与10公里,r = -0.93;最大摄氧量与10公里,r = -0.95)。这些结果证实,20-MST是心肺耐力的有效现场测试,并表明它还可用于预测10公里的相对跑步表现。
