Just 20 minutes of exercise daily reduces heart disease risk in older adults. The benefits of regular physical exercise on cardiovascular health are well established. However, most studies investigating the benefits of exercise have been conducted in younger adults rather than older ones, for whom cardiovascular disease risk is greatest. Findings from a recent study demonstrate that 20 minutes of exercise daily reduces the risk of cardiovascular disease in older adults.

The authors of the study drew on data from the Progetto Veneto Anziani, a long-term cohort study of more than 3,000 older adults (65 years and older) living in northern Italy. They identified participants with cardiovascular disease based on information gleaned from medical exams or hospital records. Every five years (at 65, 70, 75, 80, and 85 years of age), the authors assessed the participants' physical activity levels based on information provided in questionnaires.

The risk of cardiovascular-related events or premature death was lower among older adults who were physically active. Men, in particular, were half as likely to experience a cardiovascular event if they were physically active. The effects of exercise were dose-dependent, with 20 minutes of moderate- to vigorous-intensity exercise daily providing the greatest benefits, especially when performed earlier in one’s later years, between the ages of 70 and 75 years. Exercising more than 40 minutes daily provided no additional benefits.

Although the authors of this study did not differentiate between the effects of different types of exercise, their findings demonstrate that aerobic exercise is particularly beneficial for cardiovascular health. Learn more about aerobic exercise in our overview article.
