Background: Brachial-ankle pulse wave velocity (baPWV) is a reliable method for measuring arterial elasticity, but the absence of reference value for baPWV has limited its wide use. We conducted an epidemical study in north China to investigate the reference value of baPWV for Chinese people and its influential factors.
Methods: A total of 974 identified healthy subjects were recruited in this study. The values of baPWV were evaluated noninvasively with an automatic device.
Results: For healthy population, the mean value of baPWV was higher for male (P < 0.001). Multiple regression analysis demonstrated that both age and systolic blood pressure were positively associated with baPWV for male and female (P < 0.001). BaPWV value was higher in male than in female in younger group (< 50 years) but not in older group (P
Conclusions: Aging is the most important reason of arterial stiffness, but the effect of age on baPWV augmentation is greater for healthy female than their male counterpart. The reference values of baPWV by sex and age are very useful for clinical and preventive medicine.

Although the relationships between basic clinical parameters and white matter hyperintensity (WMH) have been studied, the associations between vascular factors and WMH volume in general populations remain unclear. We investigated the associations between clinical parameters including comprehensive vascular factors and WMH in two large general populations. This retrospective, cross-sectional study involved two populations: individuals who underwent general health examinations at the Asan Medical Center (AMC) and participants from a regional cohort, the Korean Genome and Epidemiology Study (KoGES).

The present study examined factors associated with trunk skeletal muscle thickness (MT, an index for the amount of skeletal muscle) and echo intensity (EI, an index for the content of non-contractile tissue, such as intramuscular adipose tissue) in young Japanese men and women in consideration of habitual dietary intake. Healthy men (n = 26) and women (n = 24) aged 20 to 26 were enrolled. Trunk MT and EI were evaluated using ultrasound imaging at the height of the 3rd lumbar vertebra.

Chicken essence (CE) is known for its antihypertensive properties. However, few studies have investigated the effects of CE in prehypertensive individuals. Here, we conducted a randomized crossover clinical trial on prehypertensive offspring of hypertensive parents to evaluate the effects of preworkout CE consumption (CEC) on post-exercise hypotension (PEH) and cardiac autonomic and vascular responses.

Article Synopsis
- Swimmers exhibit higher arterial stiffness (measured by PWV) compared to cyclists, despite having similar peak oxygen uptake levels.
- Heart-brachial PWV is lower in swimmers than in untrained controls, suggesting benefits specific to this group.
- Aerobically trained cyclists show greater reductions in brachial-ankle PWV compared to both swimmers and controls, indicating a difference in cardiovascular adaptations between these exercise modes.

In elderly women, hormonal changes lead to elevated body fat content, which results in elevated levels of vascular inflammatory factors, thereby increasing the risk of cardiovascular diseases (CVDs) associated with endothelial dysfunction. Regular physical exercises tend to keep these in check and are protective to the body. Aerobic exercise has been reported to improve CVD in obese elderly women; in this regard, aquatic exercises have been demonstrated to be more efficient in energy metabolism than land-based exercise.
