Suggests exaggerated hypoxic HR suppression in EIAH cyclists; leaves open mechanisms and performance relevance pending larger studies.
Does acute moderate hypoxia decrease peak heart rate more in endurance-trained cyclists with exercise-induced arterial hypoxemia compared to those without?
Acute moderate hypoxia leads to a more pronounced reduction in peak heart rate in endurance-trained cyclists who exhibit exercise-induced arterial hypoxemia.
Grataloup et al. (2007) studied this question.
