Weekly Fitness Tip: Secret to Staying Young, Exercise

Regular exercise can reverse age-related brain decline, according to a U.S. cognitive neuroscientist.

Prof. Art Kramer, of the Beckman Institute at the University of Illinois, says there’s substantial evidence showing the benefits of aerobic exercise and physical activity on such executive-control brain functions as task coordination, planning, goal maintenance, working memory and the ability to switch tasks.

As people age, a deterioration of white and gray matter in certain areas of the brain can cause cognitive decline, Kramer explained. He reviewed published research and found that several studies showed that regular moderate exercise that makes a person breathless increases the speed and sharpness of thought, the actual volume of brain tissue, and the way in which the brain functions. – The AGS Foundation for Health in Aging

Weekly Fitness Tip: Your Prescription Should Say Exercise

Too Few Doctors are Prescribing Exercise a new study suggests.

Using data from a government health survey, researchers found that only one-third of U.S. adults with high blood pressure said their doctors had counseled them on getting regular exercise. But of those who did get such advice, 71 percent followed it and had lower blood pressure than their counterparts who remained inactive, the investigators report in the journal Ethnicity & Disease.

The findings are based on a federal health survey that included 4,686 U.S. adults with high blood pressure. Of these participants, 33 percent said their doctors had told them to exercise regularly to help lower their blood pressure.

Dr. Josiah Halm, of the University of Wisconsin School of Medicine and his colleagues suggest that doctors think about exercise as a prescription, and actually write down on a prescription pad the type, intensity and duration of exercise each patient should try.

Weekly Fitness Tip: Shop the Perimeter and Check the Label

Are you trying to eat a more healthful and balanced diet?

Focus on the outer aisles of your supermarket as much as possible.
Many supermarkets are designed in a similar way: produce, dairy, meats, fish and breads form the perimeter of the store. Cookies, candies, chips, ice cream and other less healthy foods line the many of the middle aisles. So if you’re trying to create a healthy mix of proteins, fruits, veggies, and grains, shopping around the edges is a good way to start.

You can’t judge a wheat bread by its package – or by its color.
If you want the dietary fiber and other nutrients that whole-grain breads can provide, be sure to buy loaves that say “100% WHOLE WHEAT. Many “wheat” breads are made with mostly white flour (as much as 75%!) and a much smaller amount of wheat flour. White flour has considerably less fiber and lower amounts of certain minerals and B vitamins. Check the ingredients list on the nutrition label; if “flour” or “white flour” appear near the top of the list, you could be getting much less fiber than you think.

Sportsplex Weekly Fitness Tip: Physical Fitness Fights Weight Gain

Personal Training can help counter act genetics when it comes to weight gain.

High levels of physical activity can help to counteract a gene that normally causes people to gain weight, according to a new study by researchers at the University of Maryland School of Medicine. They analyzed gene variants and activity levels of the Old Order Amish in Lancaster County, Pa., and found that the obesity-related FTO gene had no effect on individuals who were the most physically active.

“Our results strongly suggest that the increased risk of obesity due to genetic susceptibility can be blunted through physical activity,” the authors conclude. “These findings emphasize the important role of physical activity in public health efforts to combat obesity, particularly in genetically susceptible individuals.” The results of the study are being published in the Sept. 8, 2008, issue of the Archives of Internal Medicine. – IHRSA
