- In a new study, researchers found that increasing physical activity led to 11 percent drop in heart disease risk among people age 60 and older.
- Alternately, stopping physical activity increased heart disease risk by 27 percent.
- Researchers say the findings show it’s never too late to start working out.
Getting older doesn’t give you a pass from working out, according to anew study.
Instead researchers found that increasing physical activity, even in your golden years, reduces the risk of heart disease and stroke.
Researchers found the level of activity needed to experience this benefit was equal to about 1 hour of running per week.
“It’s in line with studies of other treatment interventions that show its clearly never too late to improve things,” agreed Dr.Michael Miyamoto, a cardiologist with Mission Hospital in Southern California. “It’s also in line with other studies of exercise specifically showing that even those who take up exercise later in life will see clinical benefit.”
Researchers looked at over 1 million men and women 60 years of age and older given two consecutive health checks by the Korea National Health Insurance Service from 2009 to 2010, and 2011 to 2012.
During each one, they were asked questions about their lifestyle and physical activity level. Researchers calculated the amount of moderate and vigorous exercise participants did each week and any changes between the health checks.
A little over 20 percent of inactive seniors at the first check had increased their physical activity by the second, according to the study. These people experienced an 11 percent reduced risk of cardiovascular disease.
“We weren’t surprised by our findings as we expected the cardiovascular health benefits of exercise among older adults,” lead study author Kyuwoong Kim, a PhD student at Seoul National University Graduate School department of biomedical sciences in Seoul, told Healthline.

“Activity is the key. Ideally, anyone at any age should routinely stimulate the heart and lungs so that the heart rate increases and the breathing rate increases,” saidDr. Thomas F. Boyden, MS, program director of preventive cardiology at SHMG Cardiovascular Medicine in Grand Rapids, Michigan. “Stimulation of the cardiovascular and respiratory systems reduce the risk of cardiovascular disease like heart attack and stroke, and reduces cancer risk and all-cause mortality.”
People with a disability had 16 percent reduced disease risk, and those living with diabetes, high blood pressure, or elevated cholesterol levels reduced their risk by up to 7 percent.
However, 54 percent of participants who said they exercised at least five times per week at their first screening had become inactive by the time of the second. These individualsincreasedtheir risk of cardiovascular problems by 27 percent.
“The findings align very well withHealth and Human Services‘ recent document with regard to physical activity and its benefits; in brief that physical activity is associated with a reduction of cardiovascular disease,” said理查德·c·贝克尔博士, director of the division of cardiovascular health and diseases at UC Health in Cincinnati, Ohio.
“This is the first time I’ve seen this articulated as well as it was, that the benefits of physical activity were not sustained if a person stopped exercising,” said Becker.
据Kim说,这项研究是由两个fac有限tors; observed changes in exercise frequency were based on a self-reported questionnaire, and the data came from older adults from a single ethnic group (Koreans). “Therefore, in the future, findings need to be confirmed in a multi-ethnic cohort,” Kim said.
Information was missing on other types of physical activity as well, like housework, and muscle strengthening activities. Researchers were also unable to assess the reasons why some participants changed their physical activity level because this was an observational study using real world data and not an interventional one.
The findings have significant implications for an aging world.
“Globally, this finding is of public health importance because the world’s population aged 60 years and older is expected to total 2 billion by 2050, which is an increase from 900 million in 2015 according to the World Health Organization,” Kim said in astatement.
According to 2014
While there aren’t any official fitness guidelines for older adults, thebasic exercisesfor seniors are the same ones for any age.
However, experts emphasize that sedentary people shouldn’t just jump into a fitness routine.
“Someone who has been very sedentary it’s probably advisable for them to talk it over with their doctor. A subset of those people might benefit from undergoing a baseline assessment to ensure they’re safe to exercise,” said Miyamoto. “Also to give a prescription for the level of exercise — how intensely or vigorously they should start out. But usually, most people will be able to begin some type of exercise regimen.”
People 60 years and older who exercised more reduced their risk of cardiovascular disease by 11 percent while those who became sedentary raised their risk by 27 percent, according to new research.
电动汽车en older people living with disabilities or chronic conditions like high blood pressure or diabetes benefited from exercise.
Experts say it’s a good idea to speak with your healthcare provider before beginning an exercise routine to find the best way to proceed for your age and fitness level.
