Muscle chemoreflex increases renal sympathetic nerve activity during exercise.
Activation of the muscle chemoreflex increases sympathetic drive to skeletal muscle in humans. This study investigated whether activation of the muscle chemoreflex augments the renal sympathetic nerve activity (RSNA) response to dynamic exercise in rabbits. The muscle chemoreflex was evoked by hindlimb ischemia during exercise on a motorized treadmill. Seven New Zealand White rabbits performed ...
متن کاملAugmentation of exercise-induced muscle sympathetic nerve activity during muscle heating.
The muscle metabo- and mechanoreflexes have been shown to increase muscle sympathetic nerve activity (MSNA) during exercise. Group III and IV muscle afferents, which are believed to mediate this response, have been shown to be thermosensitive in animals. The purpose of the present study was to evaluate the effect of muscle temperature on MSNA responses during exercise. Eleven subjects performed...
متن کاملModulation of muscle sympathetic nerve activity to muscle heating during dynamic exercise.
Previous studies from our laboratory have demonstrated that altering muscle temperature of the exercising forearm can elicit changes in muscle sympathetic nerve activity (MSNA) during ischemic isometric handgrip. The purpose of the current study was to determine the interactive effect of muscle temperature and blood flow on MSNA responses during dynamic handgrip (DHG). Eight subjects performed ...
متن کاملMuscle pain perception and sympathetic nerve activity to exercise during opioid modulation.
The purpose of this experiment was to examine the effects of the endogenous opioid system on forearm muscle pain and muscle sympathetic nerve activity (MSNA) during dynamic fatiguing exercise. Twelve college-age men (24 +/- 4 yr) performed graded (1-min stages; 30 contractions/min) handgrip to fatigue 1 h after the ingestion of either 60 mg codeine, 50 mg naltrexone, or placebo. Pain (0-10 scal...
متن کاملMuscle sympathetic nerve activity during cold stress and isometric exercise in healthy older adults.
Cardiovascular mortality increases in cold weather in older adults, and physical activity may impart even greater cardiovascular risk than cold exposure alone. Human aging is associated with exaggerated pressor responses to whole body cooling; however, the sympathetic response to cold stress alone and in combination with isometric exercise is unknown. We hypothesized that cold stress would 1) i...
