Effect of exercise intensity on mild rhythmic-handgrip-exercise-induced functional sympatholysis.
This study attempts to clarify whether intensity of exercise influences functional sympatholysis during mild rhythmic handgrip exercise (RHG). We measured muscle oxygenation in both exercising and non-exercising muscle in the same arm in 11 subjects using near infrared spectroscopy (NIRS), heart rate, and blood pressure. We used the total labile signal to assess the relative muscle oxygenation ...
متن کاملImpact of ischemic preconditioning on functional sympatholysis during handgrip exercise in humans
Repeated bouts of ischemia followed by reperfusion, known as ischemic preconditioning (IPC), is found to improve exercise performance. As redistribution of blood from the inactive areas to active skeletal muscles during exercise (i.e., functional sympatholysis) is important for exercise performance, we examined the hypothesis that IPC improves functional sympatholysis in healthy, young humans. ...
متن کاملNo effect of menstrual cycle phase on glucose kinetics and fuel oxidation during moderate-intensity exercise.
Resting and exercise fuel metabolism was assessed in three different phases of the menstrual cycle, characterized by different levels of estrogen relative to progesterone: early follicular (EF, low estrogen and progesterone), midfollicular (MF, elevated estrogen, low progesterone), and midluteal (ML, elevated estrogen and progesterone). It was hypothesized that exercise glucose utilization and ...
متن کاملDiastolic Heart Sounds during Static (Handgrip) Exercise
In order to determine the frequency of third and fourth heart sounds during cardiovascular stress, 61 patients with chest pain syndromes and normal resting phonocardiograms underwent phonocardiography both before and during submaximal handgrip exercise. Cardiac catheterization, selective coronary arteriography, and left ventriculography were performed in all patients. Twenty-nine had phonocardi...
متن کاملResponse of heart murmur intensity to isometric (handgrip) exercise.
murs was evaluated in 36 patients and the results compared with the effects of amyl nitrite and phenylephrine. The isometric handgrip exercise produced immediate, reproducible, and significant increases in heart rate and blood pressure. It also increased the intensity of murmurs due to aortic and mitral regurgitation and mitral stenosis and attenuated the murmurs of left ventricular outflow tra...
