Reduction of Arterial Stiffness by Exercise Training Is Associated with Increasing Plasma Apelin Level in Middle-Aged and Older Adults
Figure 2
Percent change of plasma nitrite/nitrate (NOx: A) and apelin (apelin: B) concentrations in middle-aged and older adults before and after 8 weeks of either exercise training (Training group, n = 18) or sedentary living (Control group, n = 16).
Open bar: sedentary control group, solid bar: aerobic exercise–training group. Data are expressed as the means ± SE.
