Cardiac Responses to Isometric Exercise
The time course of cardiocirculatory responses to different levels of isometric handgrip (IHG) in sitting position were studied noninvasively in normal males and compared to supine IHG results in the same subjects. Control Comparisons. Resting postural differences were as expected: sitting heart rates (HR), preejection phase (PEP) and PEP/LVET were higher while left ventricular ejection time (L...
متن کاملRegular physical exercise improves cardiac autonomic and muscle vasodilatory responses to isometric exercise in healthy elderly
The objective of this study was to evaluate cardiac autonomic control and muscle vasodilation response during isometric exercise in sedentary and physically active older adults. Twenty healthy participants, 10 sedentary and 10 physically active older adults, were evaluated and paired by gender, age, and body mass index. Sympathetic and parasympathetic cardiac activity (spectral and symbolic hea...
متن کاملAcute cardiac functional and mechanical responses to isometric exercise in prehypertensive males
Isometric exercise (IE) training has been shown to reduce resting arterial blood pressure (ABP) in hypertensive, prehypertensive, and normotensive populations. However, the acute hemodynamic response of the heart to such exercise remains unclear. We therefore performed a comprehensive assessment of cardiac structure, function, and mechanics at rest and immediately post a single IE session in 26...

متن کاملDeterminants of skin sympathetic nerve responses to isometric exercise.
Exercise-induced increases in skin sympathetic nerve activity (SSNA) are similar between isometric handgrip (IHG) and leg extension (IKE) performed at 30% of maximal voluntary contraction (MVC). However, the precise effect of exercise intensity and level of fatigue on this relationship is unclear. This study tested the following hypotheses: 1) exercise intensity and fatigue level would not affe...
