Twelve county standard hockey players completed a 30 second sprint on a non-motorised treadmill and an uphill treadmill running test to determine maximum oxygen uptake (VO2 max) before and after 6 weeks of high intensity training (fast runs 3-5 miles, intervals 30-300 m and circuit training), whilst 11 club standard players completed the same tests without any additional training. For the county standard group there was an 11.1% and 5.0% improvement in peak running speed and distance covered on the sprint treadmill respectively, a 4.2% improvement in VO2 max and an 11.5% improvement in run time to exhaustion during the VO2 max test (all p less than 0.01). No changes were observed for the club standard group. There were large increases in blood lactate (county group 13.26 +/- 1.83 mM) and blood glucose (county group 1.56 +/- 0.71 mM) concentrations as a result of the treadmill sprint, but there were no additional changes in these variables as a result of training. Thus, the mechanism of adaptation in this type of brief maximal exercise remains in question.
12名县级标准曲棍球运动员在非电动跑步机上进行了30秒冲刺，并进行了爬坡跑步机跑步测试，以确定在为期6周的高强度训练（快速跑3 - 5英里、间歇跑30 - 300米和循环训练）前后的最大摄氧量（VO2 max），而11名俱乐部标准运动员在没有任何额外训练的情况下完成了相同测试。对于县级标准组，冲刺跑步机上的峰值跑步速度和覆盖距离分别提高了11.1%和5.0%，VO2 max提高了4.2%，在VO2 max测试中至疲劳的跑步时间提高了11.5%（所有p值均小于0.01）。俱乐部标准组未观察到变化。跑步机冲刺导致血乳酸（县级组13.26 +/- 1.83 mM）和血糖（县级组1.56 +/- 0.71 mM）浓度大幅升高，但训练并未导致这些变量出现额外变化。因此，这种短暂最大运动的适应机制仍存在疑问。
