ABSTRACTThe purpose of this review was to summarize the acute cardiovascular responses of healthy young and older adults to resistance exercise and to review studies that have compared healthy younger and older populations. Intensity, duration, and active muscle mass are known to play important roles in the degree of pressor response elicited during resistance exercise in both young and older participants. Systolic, diastolic, and mean arterial pressure as well as heart rate rise in response to resistance exercise. Stroke volume generally remains unchanged but may significantly decrease with greater exercise intensity and active muscle mass. Cardiovascular variables such as cardiac output, rate-pressure product, and oxygen consumption increase comparably in the 2 groups. Also, total peripheral resistance may increase or decrease based on involved muscle mass and resistance type. Findings from this review suggest that acute cardiovascular responses to resistance exercise are similar in healthy young and older adults. This supports the inclusion of resistance exercise as part of an overall fitness program designed for healthy older adults.
