It’s probably, even very probably, safe to assume that exercise is good for you, but it’s not entirely safe. Med Page Today reports that researchers at the University of Missouri who reviewed six recent studies of the pros and cons of exercise found that between 8 percent and 14 percent of the more than 1,600 participants had adverse changes in insulin, blood pressure, triglycerides, and HD, and about 7 percent had adverse responses in two or more risk factors. Yikes! What’s going on? That’s what the New York Times Gina Kolata asked lead researcher Claude Bouchard. His response: “It’s bizarre.” Yes. more research is needed. In the mean time, it’s safe to assume that you don’t have an excuse for not exercising.
