Supports isometric handgrip training for BP reduction in normotensives; challenges MSNA mediation and extends nonpharmacologic intervention research.
Does isometric handgrip training reduce resting arterial pressure and muscle sympathetic nerve activity in normotensive subjects?
Isometric handgrip training effectively lowers resting diastolic and mean arterial pressure in normotensive individuals, though this reduction does not appear to be mediated by changes in resting muscle sympathetic nerve activity.
Ray et al. (2000) studied this question.
