Wave Reflection and Central Aortic Pressure Are Increased in Response to Static and Dynamic Muscle Contraction at Comparable Workloads

Abstract

Wave reflection and central aortic pressure are increased in response to static and dynamic muscle contraction at comparable workloads. We determined the effects of static and dynamic muscle contraction at equivalent workloads on central aortic pressure and wave reflection. At random, 14 healthy men and women (23 +/- 5 yr of age) performed a static handgrip forearm contraction [90 s at 30% of maximal voluntary contraction (MVC)], dynamic handgrip contractions (1 contraction/s for 180 s at 30% MVC), and a control trial.
