Coordination between heart rate variability and physical activity may be diminished by fatigability in non‐older women in the hour before sleep

Abstract Fatigability is related to several diseases as well as the autonomic nervous system. We investigated whether fatigability is associated with coordination between physical acceleration (PA) and parasympathetic nervous activity (PSNA) in women. Overall, 95 women were divided into non‐old (n =...
