Government To Unveil Fitness Test For Adults

If you didn't get a Presidential Physical Fitness Award in school, the government is giving you another chance to prove you're in shape.

An adult fitness test is being introduced Wednesday by the President's Council on Physical Fitness and Sports. It will incorporate several of the exercises that millions of students undertake each year as they aim for a certificate signed by the president.

"What were trying to do is inspire and motivate Americans to move their bodies more," said Melissa Johnson, executive director of the council.

The test involves three basic components: aerobic fitness, muscular strength and flexibility. The test is for people 18 and older who are in good health. It was inspired by scores of baby boomers who kept asking council members whether there was a fitness test available today that was similar to the ones they took as students, Johnson said.

The aerobic component of the tests consists of a one-mile walk or 1.5-mile run. Push-ups and half sit-ups make up the strength test. A stretching exercise called the "sit-and-reach" is used to measure flexibility.

The scores from all four of the fitness tests can be entered online. Other information, such as age, gender, height and weight are also part of the equation.

The results show where participants rank among people of the same age. The test will allow people to easily record a baseline that they can work from through their exercise routine.

"The point is to do consistent, regular physical activity and these are good check-in points to see how fit people are," Johnson said.

Teen exercise protects against breast cancer later in life

WASHINGTON -- Get your daughters off the couch: New research shows exercise during the teen years -- starting as young as age 12 -- can help protect girls from breast cancer when they're grown.

Middle-aged women have long been advised to get active to lower their risk of breast cancer after menopause.

What's new: That starting so young pays off, too.

Researchers tracked nearly 65,000 nurses ages 24 to 42 who enrolled in a major health study. They answered detailed questionnaires about their physical activity dating back to age 12. Within six years of enrolling, 550 were diagnosed with breast cancer before menopause. A quarter of all breast cancer is diagnosed at these younger ages, when it's typically more aggressive.

Women who were physically active as teens and young adults were 23 percent less likely to develop premenopausal breast cancer than women who grew up sedentary, researchers reported last week in the Journal of the National Cancer Institute.

The biggest impact was regular exercise from ages 12 to 22.

The women at lowest risk reported doing three hours and 15 minutes of running or other vigorous activity a week -- or, for the less athletic, 13 hours a week of walking. Typically, the teens reported more strenuous exercise; during adulthood, walking was most common.

Why would it help? A big point of exercise in middle age and beyond is to keep off the pounds. After menopause, fat tissue is a chief source of estrogen.

In youth, however, the theory is that physical activity itself lowers estrogen levels. Studies of teen athletes show that very intense exercise can delay onset of menstrual cycles and cause irregular periods.

Study: Over half of Americans on chronic medicines

TRENTON, N.J. -- For the first time, it appears that more than half of all insured Americans are taking prescription medicines regularly for chronic health problems, a study shows.

The most widely used drugs are those to lower high blood pressure and cholesterol -- problems often linked to heart disease, obesity and diabetes.

The numbers were gathered last year by Medco Health Solutions Inc., which manages prescription benefits for about one in five Americans.

Experts say the data reflect not just worsening public health but better medicines for chronic conditions and more aggressive treatment by doctors.

In addition, there is the pharmaceutical industry's relentless advertising. With those factors unlikely to change, doctors say the proportion of Americans on chronic medications can only grow.

Americans buy much more medicine per person than any other country. But it was unclear how their prescriptions compare to those of insured people elsewhere. Comparable data were not available for Europe, for instance.

Medco's data show that last year, 51 percent of American children and adults were taking one or more prescription drugs for a chronic condition, up from 50 percent the previous four years and 47 percent in 2001. Most of the drugs are taken daily, although some are needed less often.

The company examined prescription records from 2001 to 2007 of a representative sample of 2.5 million customers, from newborns to the elderly.
