Heart rate variability during static and dynamic breath-hold dives in elite divers
Autonomic Neuroscience: Basic and Clinical, 07/27/2012
Kiviniemi AM et al. – The authors concluded that apnea blunts the effects of exercise on cardiac vagal activity at the end of DA. However, higher heart rate (HR) during dynamic (DA) compared with static (SA) indicates larger cardiac sympathetic activity during DA, as suggested also by slightly higher (alpha)1.
