Effects of diet and/or low-intensity resistance exercise training on arterial stiffness, adiposity, and lean mass in obese postmenopausal women.

Background: Obesity and aging are associated with increased arterial stiffness as indicated by an increased pulse-wave velocity (PWV). We evaluated the independent and combined effects on PWV and body composition of a hypocaloric diet and low-intensity resistance exercise training (LIRET) with slow movement.

Methods: Forty-one postmenopausal women (mean age, 54±6 years; body mass index (BMI), 33.

Whole-body vibration training reduces arterial stiffness, blood pressure and sympathovagal balance in young overweight/obese women.

Obesity is associated with early cardiovascular dysfunction and reduced muscle strength. Whole-body vibration (WBV) training may improve arterial function and muscle strength. The effects of WBV training on arterial stiffness (brachial-ankle pulse wave velocity, baPWV), wave reflection (augmentation index, AIx), brachial systolic blood pressure (bSBP), aortic systolic blood pressure (aSBP), heart rate variability, and muscle strength (one-repetition maximum, 1RM) were examined in 10 young (21 ± 2 year) overweight/obese women (body mass index, BMI = 29.

Acute exercise with whole-body vibration decreases wave reflection and leg arterial stiffness.

Aim: Whole-body vibration exercise (WBV) acutely decreases brachial-ankle pulse wave velocity (baPWV), an index of systemic arterial stiffness. However, the effect of WBV on segmental PWV and aortic hemodynamics is unknown. We examined the acute effects of WBV on arterial function.

Creatine supplementation attenuates hemodynamic and arterial stiffness responses following an acute bout of isokinetic exercise.

Arterial stiffness and hemodynamics may be increased following a bout of resistance exercise. Oral creatine supplementation (Cr) may attenuate cardiovascular responses after exercise via improved anaerobic metabolism. This study was aimed to determine the effect of Cr on hemodynamic and arterial stiffness responses after acute isokinetic exercise.

Oral L-citrulline supplementation attenuates blood pressure response to cold pressor test in young men.

Background: Oral L-citrulline is efficiently converted to L-arginine, which has been shown to decrease brachial blood pressure (BP) at rest and during the cold pressor test (CPT). However, aortic BP may better reflect cardiovascular risk than brachial BP. The purpose of this study was to test the hypothesis that oral L-citrulline supplementation attenuates brachial BP and aortic hemodynamic responses to CPT.
