Research Abstract |
This study aimed to clarify the effects of regular aerobic exercise on apelin concentrations in middle-aged and older adults. Thirty-four healthy middle-aged and older subjects were randomly divided into two groups: exercise intervention and sedentary controls. Subjects in the training group completed 8-week of aerobic exercise training (60-70% peak oxygen uptake [VO2peak] for 45 min, 3 days/week). In the training group, VO2peak was significantly increased, and carotid beta-stiffness was significantly decreased, after the intervention. Moreover, plasma apelin and NOx levels were significantly increased in the training group after the intervention. Additionally, there was a correlation between the training effects of plasma apelin levels and carotid beta-stiffness (r = -0.508, P = 0.032). These results suggest that the increased in plasma apelin levels may be associated with exercise training-induced alternation of arterial stiffness in middle-aged and older adults.
