摘要

在跑步机上测定了59名平均年龄为11.8岁的儿童乳酸门槛心率(HR)。45分钟后,他们必须在自行车测力仪上进行vita maxima测试。负载以10瓦特/分钟的速度逐步增加。在测试期间,HR连续注册并每5秒存储一次。52例患儿的特征性断点明显;在7名儿童中没有发现断点-在2名儿童中,因为他们在达到乳酸阈值之前停止了运动,在5名儿童中,因为他们的HR从开始到负荷应用结束呈线性增加。断点HR与乳酸阈值HR相关性非常强(r = 0.99)。因此,作者认为Conconi试验的改进可以替代有创性儿童乳酸阈值测定。

[Comparison of heart rate to lactate threshold and to Conconi's threshold in children].

The heart rate (HR) at the lactate threshold was determined on a treadmill in 59 children with an average age of 11.8 years. 45 minutes later, they had to go through a vita maxima test on a bicycle ergometer. The load was increased stepwise by 10 Watt/min. During the tests HR was registered continually and stored every 5 seconds. In 52 children the characteristic break point was evident; in 7 children no break point could be found - in 2 children, because they had stopped the exercise before reaching the lactate threshold, and in 5 children because their HR increased linearly from the beginning until the end of the load application. HR at the break point correlated very strongly with HR at the lactate threshold (r = 0.99). Therefore the authors are of the opinion that the introduced modification of the Conconi test can substitute the invasive lactate threshold determination in children.
