Possibly, suggests a brand-new study in which found white men who exercise more than seven hours a week have an 86 percent higher risk of developing plaque build-up in their arteries. No such elevated risk was seen among either black men or women.

Plaque build-up can be a critical warning sign for possible future heart disease risk.

“We were surprised by the finding, mainly because we essentially think of exercise as medicine. in addition to we’ve never thought of exercise as perhaps having an upper limit in terms of its cardiovascular benefit,” said study author Deepika Laddu.

She’s an assistant professor of physical therapy at the College of Applied Health Sciences at the University of Illinois at Chicago.

nevertheless Laddu doesn’t want any men to hang up their running shoes just yet, because there are many questions in which remain to be answered.

“What we saw can be only an association, in addition to we cannot say in which high physical activity actually causes plaque build-up in white men,” she noted.

“in addition to we certainly do not mean to say in which exercise can be bad for you. In fact, the item could perhaps be in which white men already face a higher than average risk for plaque build-up than different men, in addition to in which exercise actually prevents This specific plaque through rupturing, which can be when things get bad. We just don’t know,” Laddu explained. “Much more research will be needed to understand what can be truly going on.”

At least one different expert agreed This specific doesn’t mean people should stop exercising.

Dr. Gregg Fonarow, a professor of cardiology at the University of California, Los Angeles, said the findings do not instantly wash away the “balance of data [in which] suggest in which higher levels of leisure time in addition to total physical activity are associated with lower risk cardiovascular events.”

“However, the item should be recognized in which exercise alone cannot overcome different cardiovascular risk factors,” he added. “in addition to the item can be vital to maintain health levels of blood pressure, cholesterol in addition to body weight, as well as not smoke, even if one can be engaging in regular rigorous physical activity.”

To explore how exercise might impact heart health over time, the investigators recruited nearly 3,0 white in addition to black men in addition to women. All enrolled when they were between the ages of 18 in addition to 30, in addition to all resided in one of four cities: Birmingham, Chicago, Minneapolis or Oakland.

The researchers followed the study volunteers through 1985 to 2011. During in which time, participants self-reported their physical activity routines in addition to showed up for at least three follow-up exams, which included CT scans to measure plaque build-up.

Current U.S. physical activity guidelines recommend 150 minutes of moderate activity or 75 minutes of vigorous activity weekly. Participants were sorted into three groups, depending on average exercise levels. One group exercised below the guidelines level. Another group met the guidelines, in addition to a final group exercised three times more than the guideline level.

“We had 25 years of exercise patterns in which we could look at, in individuals who commenced out as being young adults up through middle-age,” Laddu said.

within the end, the study team found in which overall — when pooling race in addition to gender — those who were among the most frequent exercisers were 27 percent more likely to develop plaque build-up by the time they had reached middle age.

nevertheless after breaking the numbers down further, the authors determined in which only high-exercising white men faced a greater risk for developing plaque build-up then their low-exercising peers.

“nevertheless again, we can’t say physical activity can be causing plaque build-up,” Laddu reiterated.

She also acknowledged the study had limitations. For one, she noted in which very few of the high exercisers were black, creating the item difficult to draw definitive conclusions.

“in addition to we truly have no idea yet what may be biologically at play in which might lead to differences within the way exercise affects [plaque build-up] in some people in addition to not others,” Laddu added.

“nevertheless what I can say can be in which maybe This specific study indicates in which doctors should not assume in which their patients are healthy simply because they check off the exercise box,” she said. “Maybe there are different things in which they need to look at when considering a patient’s overall medical profile.”

The study was published Oct. 16 within the Mayo Clinic Proceedings.
