Nod if these scenarios seem familiar:
You give your client well-articulated instructions and get a blank stare followed by, “So what do you want me to do?”
You give your client a series of cues, but the client’s movements actually get worse because your point is misunderstood.
You have a successful training session one week where the client really seems to click with everything you are saying, but the next week it is as though your coaching had dissolved and the client is right back to those inefficient movements.
A Tufts University study led by Adela Hruby, PhD, MPH, has found that healthy people with the highest magnesium intake were 37% less likely to develop high blood sugar or excess circulating insulin, common precursors to diabetes.
Among people who already had those conditions, those who consumed the most magnesium were 32% less likely to develop diabetes than those consuming the least.
The second association held true even when researchers accounted
for other healthful factors—such as fiber—that often go along with magnesium-rich foods.
It may be time to focus health promotion efforts toward Asian Americans. Research from the Journal of the American College of Cardiology (2014; 64 , 2486–94) says that this population has a significantly high risk of dying from heart disease or stroke.
Using U.S. census data and death records, researchers examined death rates among the largest Asian subgroups (Asian-Indian, Chinese, Filipino, Japanese, Korean and Vietnamese). They then narrowed their search to deaths caused by heart disease and stroke. Overall, the researchers combed 10,442,034 death records.
Some of us call it “afterburn”—the elevated calorie burning that lasts long after exercise is over. The scientific literature defines it as excess postexercise oxygen consumption, or EPOC (see Figure 1).
For the most part, EPOC represents the body restoring itself from physiological variables elevated by exercise. EPOC is an important physiological phenomenon for fitness professionals because it can play a contributing role in weight management.
In the January issue of IDEA Fitness Journal (2014; 12 , 11), we reported on the significant increase in osteoporotic fractures among men in recent years. A new report shows that losing weight may increase hip fracture risk.
When a person loses weight, have you ever wondered where it goes? Scientists at the University of New South Wales in Australia have put together a calculation to explain the process. And it turns out most expert theories are wrong.
It’s 11:00 pm and cold outside. Mary taps her wrist and sees she is 1,000 steps short of her daily goal. For the last month she has been diligent about hitting her daily activity target. Even though her knee hurts and her body feels drained, she puts on warm clothes and goes for a late-night stroll around her neighborhood.
Highlighting the importance of the mind-body relationship, a new study has found that 7- to 9-year-old participants in an after-school fitness program improved their cognitive skills, enhancing their academic performance.
