During sustained isometric exercise, central command has very little effect on muscle sympathetic nerve activity (MSNA). To determine if central command has a greater effect on MSNA during intermittent than during sustained contractions, MSNA was recorded with microelectrodes (peroneal nerve) during intermittent isometric handgrip at 25%, 50%, and 75% maximum voluntary contraction (MVC) in 9 human subjects with paced breathing. Similar experiments were performed in 11 additional subjects before… CONTINUE READING
