Is There Such a Thing as Too Much Exercise??

Middle-aged white men are at a higher risk of developing plaque in their arteries if they do intense exercises, researchers say.A new study suggests that there is such a thing as too much exercise, – at least for middle-aged white men.

According to researchers at the University of Illinois at Chicago and Kaiser Permanente, white men, in particular, who exercise at high intensities are 86 percent more likely to develop plaque buildup in their arteries than those who exercise at low intensities.

The link was not seen in black men, however.

To find this out, researchers studied the physical activity trajectories of 3,175 white and black participants in the  Coronary Artery Risk Development in Young Adults (CARDIA) study with baseline ages of 18 to 30, and looked at the presence of coronary artery calcification (CAC) in participants.

(CAC is the buildup of calcium and plaque in the arteries of the heart. It can be a significant warning sign of impending heart disease, the study explains.)

After accounting for age and race, the team was able to find that white men were at the highest risk. There was a similar trend for white women, the study says, but it was not statistically significant.
