Strength Training Is Better Than Aerobics for Cardiac Protection
Static exercise, such as strength training, might be superior to dynamic exercise, such as walking or cycling, for conferring protection against cardiovascular disease (CVD), new research suggests.
Using data from the 2005/06 National Health and Nutrition Examination Survey (NHANES), Maia P. Smith, PhD, assistant professor, Department of Public Health and Preventive Medicine, St. George’s University, Granada, West Indies, analyzed cardiovascular risk factors in more than 4000 American adults as a function of self-reported static and/or dynamic activity.
She found that 36% of adults 21 to 44 years of age and 25% of adults older than 45 years engaged in static activity, compared with 28% and 21%, respectively, of adults engaging in dynamic activity.
Although both activities were associated with 30% to 70% lower rates of CVD risk factors, the associations were strongest for youth and for static activity.
“In over 4000 American adults from a representative sample, I found that static activity — strength training — appeared more cardioprotective than dynamic activity — in this case, walking, and biking,” Smith told theheart.org | Medscape Cardiology.
“The odds of having a given risk factor — hypertension, overweight/obesity, diabetes, or high cholesterol — were between one-third and two-thirds lower for those who engaged in static activity than for those who engaged in no activity, but although dynamic activity wasn’t as good as static, it still had some benefits, especially for [those who were] overweight,” she said.
Their results were presented November 16 at the American College of Cardiology (ACC) Latin America Conference 2018.
