5 . Doctors have long known that diet and exercise are the best ways to stay healthy. But few people get enough exercise. Only 20% of Americans get the recommended 150 minutes of physical activity per week. More than 80 million Americans over age 6 are entirely inactive. People leading a sedentary (久坐的) life pay a price. They are at higher risk for serious health problems. These include heart disease and cancer.
Health experts want people to know about the benefits of exercise. They believe it can lead to slower aging, better moods, stronger vision—the list goes on.
This year, the U. S. National Institutes of Health (NIH) is starting a major study. It will record in detail what happens inside a body in motion (运动). Through its research，the NIH hopes to prove scientifically that exercise is good medicine.
The project will run for six years. A group of about 3, 000 sedentary people will take part in the project. They will range from 11-year-olds to the elderly. The group will begin an exercise program. Their blood, fat, and muscle will be studied before and after each workout. Scientists will look for clues to how the body changes with physical activity. A group that doesn't exercise will also be tracked. Experts will compare the two groups. Studies show that many positive changes happen in the body during and after a workout.
One of the best pieces of news is that much of what we already do counts as physical activity. “Sweeping the floor, watering the plants, washing the car—all that is exercise,” says Jack Berryman. He is a retired professor of medical history at Washington University School of Medicine, in Seattle. “Physical activity includes all movement, not just throwing a ball through a basket.”
Bamman hopes the NIH study will help doctors give each of their patients a detailed workout plan. In the meantime, here is a prescription (处方) for good health: Get active!

Pilates(普拉提), yoga and running, whether in the gym or at home, get all the attention when it comes to popular ways to keep fit.
Certified fitness professional Jolynn Jaekel explains, “What I love about walking is that anyone can do it at any age and any fitness level. Besides, it is good for your heart, your head and your wallet.
Scientists at the Lawrence Berkeley National Laboratory in California found that quick walking reduced the risk of heart disease more effectively than running.
8 . Race walking (竞走) shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.
Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing(摆动) and one foot remain in contact with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.
Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.
However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.
As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might need to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper techniques, she says. It takes some practice.
