Muscle afferent and central command contributions to the cardiovascular response to isometric exercise of postural muscle in patients with mild chronic heart failure.
The roles of muscle afferent activity and central drive in controlling the compromised cardiovascular system of patients with mild chronic heart failure (CHF) during isometric exercise were examined. Blood pressure and heart rate responses were recorded in eight stable CHF patients (ejection fraction 20-40%; age 62+/-11 years) and in nine healthy age-matched controls during voluntary and electr...
متن کاملMuscle afferent inputs to cardiovascular control during isometric exercise vary with muscle group in patients with chronic heart failure.
It is not known whether the contribution of the muscle metaboreflex to the cardiovascular response to isometric exercise varies between different muscles in patients with CHF (chronic heart failure) or whether this depends upon muscle fibre type and training status. To resolve these issues BP (blood pressure) and HR (heart rate) responses were recorded in seven stable CHF patients (ejection fra...
متن کاملCardiovascular response to isometric exercise in normal adolescents.
The purpose of this study was to document the cardiovascular response to submaximal isometric handgrip (IHG) exercise in 32 normal adolescents. Left ventricular (LV) dimensions and systolic time intervals were recorded using echocardiography; blood pressure was measured by sphygmomanometry both at rest and during IHG exercise at 25% maximum contraction. This level of isometric exercise produced...
متن کاملCardiovascular response to exercise.
This article is intended for instructors who teach cardiovascular physiology. In our physiology course exercise physiology is used as a tool to review and integrate cardiovascular and respiratory physiology. It is assumed that the students already have mastered the fundamentals of cardiovascular and respiratory physiology. Because this paper is part of a cardiovascular refresher course, I have ...
متن کاملThe Response of Skeletal Muscle-Expressed Neurotrophins to Acute Resistance Exercise in Male Wistar Rats
Background. BDNF and NT-4/5 have been proposed to be involved in the coordinated adaptations of the neuromuscular system to the elevated level of activity, but an activity-dependent expression of neurotrophins in skeletal muscle is not well established. Objectives. We, therefore, investigated the effect of one session of resistance exercise on mRNA expression of some neurotrophins in Slow and ...
