Trail running at altitude was associated with post-exertional autonomic shifts in runners; hypothesis-generating for recovery dynamics, prospective confirmation needed.
Does a 46-km wilderness trail run at altitude alter cardiovascular autonomic modulation and baroreflexes in endurance runners?
Prolonged physical exertion at altitude induces acute sympathetic predominance followed by a delayed increase in vagal sensitivity at 24 hours.
L. Bernardi (1997) studied this question.
