Exercising for 20 minutes a day in your 70s appears to be the best way older adults can live longer without heart problems, a new study reveals. Scientists in Italy say the moderate to vigorous physical activity reduced the risk of developing heart disease when these individuals reached their 80s.
Researchers have long known that physical activity lengthens lifespans and reduces the risk from cardiovascular disease, regardless of gender or ethnicity. Until now, however, few studies have probed whether exercise later in life can ward off heart attacks and strokes during old age.
For the study, the team drew on information from the Progetto Veneto Anziani study of 3,099 Italians over the age of 65. Those researchers carried out initial tests including a detailed medical history, physical examination, scans, and a range of blood tests between 1995 and 1997. Scientists conducted two further assessments four and seven years later.
Older women live with more pre-existing conditions
When the study began, women were more likely than men to have more than four co-existing conditions. Osteoarthritis, osteoporosis, and chronic kidney disease were more common among women than men, while diabetes and chronic obstructive pulmonary disease were more common among men.
