From brain to heart: cognitive performance shapes exercise- induced cardiac autonomic trajectories in older adults

Key Points

Individuals with higher cognitive performance exhibit greater adaptability in cardiac autonomic regulation during tests.
Notably, individuals with lower cognition show blunted heart rate variability (HRV) trajectories, indicating vulnerability.

Structured PICO

Does cognitive performance shape exercise-induced cardiac autonomic trajectories in older adults?

Population

Older adults

Intervention

2-Min Step Test

Outcome

Cardiac autonomic regulation (Heart Rate Variability trajectories)surrogate

2-Min Step Test-derived HRV responses may provide a non-invasive marker of cognitive health in aging.

Abstract

Older adults with better cognitive performance show healthier resting autonomic profiles and greater adaptability of cardiac autonomic regulation during a brief functional test. Blunted HRV trajectories in individuals with lower cognition may signal early neurophysiological vulnerability, and 2-Min Step Test-derived HRV responses may provide a non-invasive marker of cognitive health in aging.
