Heart rate during exercise with leg vascular occlusion in spinal cord-injured humans.
Feed-forward and feedback mechanisms are both important for control of the heart rate response to muscular exercise, but their origin and relative importance remain inadequately understood. To evaluate whether humoral mechanisms are of importance, the heart rate response to electrically induced cycling was studied in participants with spinal cord injury (SCI) and compared with that elicited dur...
متن کاملCardiovascular control during exercise: insights from spinal cord-injured humans.
BACKGROUND We studied the role of the central nervous system, neural feedback from contracting skeletal muscles, and sympathetic activity to the heart in the control of heart rate and blood pressure during 2 levels of dynamic exercise. METHODS AND RESULTS Spinal cord-injured individuals (SCI) with (paraplegia, n=4) or without (tetraplegia, n=6) sympathetic innervation to the heart performed e...
متن کاملEffects of Upper Limb Exercises on Physical Capacity and Heart Function in Quadriplegics
Objectives: Wheelchairs are the prime mobility aid of persons with spinal cord injuries. Manual wheelchair propulsion puts a lot of demand on the cardiopulmonary as well as the skeletal system. The main purpose of the study was to compare the effects of both arm ergometry training and progressive resistance exercise training of upper limbs on resting heart rate and distance covered during wheel...

متن کاملSympathetic nonadrenergic transmission contributes to autonomic dysreflexia in spinal cord-injured individuals.
Autonomic dysreflexia is a hypertensive episode in spinal cord-injured individuals induced by exaggerated sympathetic activity and thought to be alpha-adrenergic mediated. alpha-Adrenoceptor antagonists have been a rational first choice; nevertheless, calcium channel blockers are primarily used in autonomic dysreflexia management. However, alpha-adrenoceptor blockade may leave a residual vasoco...
