Why the study?
Does dynamic handgrip exercise alter mean arterial pressure and heart rate variability parameters in human participants?
Does dynamic handgrip exercise alter mean arterial pressure and heart rate variability parameters in human participants?
Changes in cardiovascular function during low-intensity handgrip exercise are primarily mediated by parasympathetic withdrawal, whereas higher intensity exercise recruits additional sympathetic outflow.

Suggests parasympathetic mediation at low-intensity handgrip; leaves open sympathetic contributions and clinical relevance pending larger studies.
