HRV inversely associated with late-race load in cyclists; hypothesis-generating for autonomic monitoring, needs prospective validation.
Does prolonged intense exercise affect resting heart rate and heart rate variability in professional cyclists?
Heart rate variability is strongly and inversely correlated with the volume and intensity of heavy exertion during prolonged professional cycling.
Earnest et al. (2004) studied this question.
