Effects of Aging on Cardiovascular Function: A Preliminary Quantitative Report. (Special Populations)

Article excerpt

Considerable research has indicated that aging is typically associated with a decline in cardiovascular function. Because the declines in cardiovascular function are so prevalent, the topic of cardiovascular aging has created considerable interest among researchers. However, the extent of aging effects on cardiovascular function varies across selected studies. This meta-analytic study quantitatively determined the effects of aging and several specific experimental characteristics on cardiovascular function of seniors. After searching database and reference lists, effect sizes (ESs) for maximal oxygen consumption ([VO.sub.2]max), heart rate (HR), and blood pressure (BP) were calculated from 48 studies that met the specific criteria of inclusion (379 ESs, 2,029 participants, 1,210 men and 819 women, from 57 to 79 years of age). Descriptive data indicated that the overall aging effects on the three cardiovascular measures ([VO.sub.2]max, HR, and BP) is substantial (mean weighted ES = 1.569) and support the hypot hesis that aging results in a decrease in cardiovascular function. Validity of experiment, gender and exercise status of the participants, type of dependent measures, and funding status of research were identified as moderator variables for the aging effects on cardiovascular function. …
