Rate pressure product in healthy individuals during an acute bout of isometric handgrip exercise

Abstract

Introduction: Meta-analyses have shown isometric resistance training (IRT) to produce a significant blood pressure lowering effect. Due to hypertensive responses during IRT some health professionals are reluctant to recommend IRT. Consequently moderate intensity aerobic exercise remains the preferred exercise modality for lowering blood pressure. Aerobic exercise at 60% max heart rate (HR) at 41 years, with HR 108 and systolic blood pressure (SBP) 140 would have a rate pressure product (RPP) of 15-20K. Aims: To measure surrogate myocardial oxygen consumption using peak RPP during IRT conducted at 'control intensities' 5%, 10% and 'intervention intensity' 30% of maximum voluntary contraction (MVC).
