The influence of blood lactate on brainstem excitability was tested by using the blink reflex (BR) recovery cycle on 18 sprinters. Blood lactate was measured before maximal cycling, at the end, as well as 5 and 10 min after the exhaustion. Blood lactate was associated with a decrement of R2 whereas only small changes were observed after an intravenous infusion of lactate. It seems, therefore, that lactate influences BR mainly by acting at the cortical level.
通过对18名短跑运动员进行眨眼反射（BR）恢复周期测试，研究了血乳酸对脑干兴奋性的影响。在最大强度骑行前、结束时以及力竭后5分钟和10分钟测量血乳酸。血乳酸与R2的降低有关，而静脉输注乳酸后仅观察到微小变化。因此，乳酸似乎主要通过作用于皮层水平来影响眨眼反射。
