The effect of aging on cardiovascular fitness is notable, as there tends to be a natural decline in cardiovascular efficiency with advancing age. Factors such as decreased maximum heart rate and reduced blood flow can diminish aerobic capacity. Additionally, aging contributes to a gradual loss of muscle mass and increased body fat, which can further compromise cardiovascular function. However, regular exercise, particularly aerobic activities and strength training, can counteract these declines by enhancing heart health and overall fitness. Prioritizing activity remains crucial for maintaining cardiovascular wellness as one ages.
