In Brief Objective: Menopause is associated with increased arterial stiffness and reduced muscle strength. Combined resistance (RE) endurance (EE) exercise training can decrease brachial-ankle pulse wave velocity (baPWV), an index of stiffness, in young men. We tested the hypothesis that combined circuit RE EE would improve baPWV, blood pressure (BP), strength postmenopausal women. Methods: Twenty-four women (age 47-68 y) were randomly assigned to a "no exercise" control (n = 12) or (EX; n...
Purpose: This study established the published prediction equations for energy expenditure of walking and running compared with measured values. To make this comparison we first determined whether differences exist in 1600 m versus running, occur due to being on track or treadmill. Methods: Energy was via indirect calorimetry 24 subjects while (1.41 m·s−1) (2.82 A subgroup also performed 1600-m run/walk track. The expenditures were equations. Results: Running required more (P < 0.01) than...
Summary Fibromyalgia (FM) is characterized by generalized muscle pain, low strength and autonomic dysfunction. Heart rate (HR) variability (HRV) reduced in individuals with FM increasing their risk for cardiovascular morbidity mortality. We tested the hypothesis that resistance exercise training (RET) improves HRV, baroreflex sensitivity (BRS) women FM. Women ( n = 10) healthy controls 9), aged 27–60 years, were compared at baseline. Only underwent supervised RET 2 days per week 16 weeks....
Oral L-citrulline is efficiently converted to L-arginine, the precursor for endothelial nitric oxide (NO) synthesis. L-arginine supplementation reduces brachial blood pressure (BP). We evaluated effects of watermelon on aortic BP and arterial function in individuals with prehypertension.Heart rate (HR), systolic (bSBP), pulse (bPP), SBP (aSBP), PP (aPP), augmentation index (AIx), AIx adjusted HR 75 beats/min (AIx@75), amplitude first (P1) second (P2) peaks, reflection time (Tr),...
Yoga has been known to have stimulatory or inhibitory effects on the metabolic parameters and be uncomplicated therapy for obesity. The purpose of present study was test effect an 8-week yoga-asana training body composition, lipid profile, insulin resistance (IR) in obese adolescent boys. Twenty volunteers with mass index (BMI) greater than 95th percentile were randomly assigned yoga (age 14.7±0.5 years, n=10) control groups 14.6±1.0 n=10). group performed exercises three times per week at...
Ankle-brachial index (ABI) and ankle blood pressure (BP) are associated with increased carotid wave reflection (augmentation index, AIx). Oral L-citrulline L-arginine from synthetic or watermelon sources have reduced brachial BP, aortic AIx. A directly measured AIx (cAIx) rather than has been proposed as a better measurement of central We evaluated the effects extract on BP cAIx in individuals normal ABI prehypertension stage 1 hypertension. Ankle systolic (SBP), diastolic (DBP), mean...
Obesity and aging are associated with increased arterial stiffness as indicated by an pulse-wave velocity (PWV). We evaluated the independent combined effects on PWV body composition of a hypocaloric diet low-intensity resistance exercise training (LIRET) slow movement. Forty-one postmenopausal women (mean age, 54±6 years; mass index (BMI), 33.8±0.5kg/m2) were randomly assigned to LIRET (n = 14), 13), or + 14) for 12 weeks. The women's PWV, mean pressure (MAP), dual-en ergy x-ray...
Ursolic acid (UA), a type of pentacyclic triterpenoid carboxylic purified from natural plants, can promote skeletal muscle development. We measured the effect resistance training (RT) with/without UA on development and related factors in men. Sixteen healthy male participants (age, 29.37±5.14 years; body mass index=27.13±2.16 kg/m(2)) were randomly assigned to RT (n=7) or with (RT+UA, n=9) groups. Both groups completed 8 weeks intervention consisting 5 sets 26 exercises, 10~15 repetitions at...
Oral L-citrulline is efficiently converted to L-arginine, which has been shown decrease brachial blood pressure (BP) at rest and during the cold pressor test (CPT). However, aortic BP may better reflect cardiovascular risk than BP. The purpose of this study was hypothesis that oral supplementation attenuates hemodynamic responses CPT.Brachial BP, stroke volume (SV), wave reflection CPT were evaluated in 17 young (21.6 +/- 0.9 years) normotensive men. Subjects randomly assigned 4 weeks (6...
Postmenopausal women have increased arterial stiffness (brachial-ankle pulse wave velocity [baPWV]) and reflection. L-Citrulline supplementation reduces baPWV but not brachial blood pressure. Peripheral vasodilators decrease reflection amplitude or second systolic peak (SBP2) in radial artery aorta, which are related to aortic pressure (SBP). We examined the effects of L-citrulline-rich watermelon on baPWV, characteristics, SBP postmenopausal women.In a randomized cross-over study, 12 (mean...
Objective The purpose of this study was to examine the impact whole-body vibration (WBV) exercise training on arterial stiffness (pulse wave velocity [PWV]), blood pressure (BP), and leg muscle function in postmenopausal women. Methods Twenty-five women with prehypertension hypertension (mean [SE]; age, 56 [1] y; systolic BP, 139 [2] mm Hg; body mass index, 34.7 [0.8] kg/m2) were randomized 12 weeks WBV (n = 13) or no-exercise control group. Systolic diastolic mean pressure, heart rate,...
Postmenopausal women have increased wave reflection (augmentation pressure (AP) and index (AIx)) reduced muscle function that predispose them to cardiac diseases disability. Our aim was examine the combined independent effects of whole-body vibration training (WBVT) l-citrulline supplementation on aortic hemodynamics plasma nitric oxide metabolites (NOx) in postmenopausal women. Forty-one obese were randomized 3 groups: l-citrulline, WBVT+l-citrulline WBVT+Placebo for 8 weeks. Brachial...
Oxidative stress and inflammation are central to the development of a number chronic diseases including cardiovascular disease previous research suggests that blueberry consumption may attenuate these processes. The present study investigated effects blueberries on blood biomarkers oxidative stress, inflammation, antioxidant defense in postmenopausal women with pre- stage 1-hypertension. In randomized, parallel-arm, double-blind, placebo-controlled clinical trial, 40 1-hypertensive aged 45...
