Why the study?
Does exercise alter the correlation properties of heartbeat fluctuations compared to rest in healthy individuals?
Does exercise alter the correlation properties of heartbeat fluctuations compared to rest in healthy individuals?
Heartbeat interval fluctuations exhibit distinct scaling and correlation patterns during exercise compared to rest, reflecting different underlying physiological states.
