1 . Two new studies suggest that modern running shoes could increase the risk of injuries to runners.

One study involved sixty-eight healthy young women and men who ran at least twenty-four kilometers a week. The runners were observed on a treadmill machine (跑步机). Sometimes they wore running shoes. Other times they ran barefoot.

Researchers from the JKM Technologies Company in Virginia, the University of Virginia and the University of Colorado did the study.

They found that running shoes create more stress that could damage knees, hips and ankle joints than running barefoot. They observed that the effect was even greater than the effect reported earlier for walking in high heels.

The study appeared in the official scientific journal of the American Academy of Physical Medicine.

The other study appeared in the journal Nature. It compared runners in the United States and Kenya. The researchers were from Harvard University in Massachusetts, Moi University in Kenya and the University of Glasgow in Scotland.

They divided the runners into three groups. One group had always run shoeless. Another group had always run with shoes. And the third group had changed to shoeless running.

Runners who wear shoes usually come down heel first. That puts great force on the back of the foot. But the study found that barefoot runners generally land on the front or middle of their foot. That way they ease into their landing and avoid striking their heel.

Harvard’s Daniel Lieberman led the study. He says the way most running shoes are designed may explain why those who wear them land on their heels. The heel of the shoe is bigger and heavier than other parts of the shoe, so it would seem more likely to come down first. Also, the heel generally has thick material under it to soften landings.

But the researchers do not suggest that runners immediately start running barefoot. They say it takes some training. And there can be risks, like running when your feet are too cold to feel if you get injured.

The study was partly supported by Vibram, which makes a kind of footwear that it says is like running barefoot. The findings have gotten a lot of attention. But the researchers say there are many problems in the way the press has reported in their paper. So they have tried to explain their findings on a Harvard Website.

B．Two new discoveries encourage people to run in high heels.

C．Running in shoes is partly good to runners.

D．Two new studies prove running without shoes is beneficial to runners in most cases.

2 . The dangers of sitting all day are obvious. Researchers have shown that remaining sitting for extended periods of time (like at your 9-to-5 desk job) can do harm to your health. While exercise is a big part of reducing the harmful effects of sitting, it was unclear how many gym periods were needed to help – until now.

A new study, published in The Lancet, shows the ideal formula for reducing the negative effects of a sedentary（久坐的）job. Instead of a fixed number of hours spent exercising, the ratio（比率）depends on how much you sit: people who work a typical eight-hour day should spend at least one hour each day moving. If you sit six hours a day, you should spend half an hour exercising. The research also indicates that the exercise doesn’t have to be all once – or rigorous（严格的）. It can be spread throughout the day and be as simple as walking.

The team behind the study analyzed data from a pool of a million adults over the age of 45 in Western Europe, the United States, and Australia. Using previous data, the researches examined data from 16 published studies and used it to determine how much exercise is required to compensate for sitting. Their recommended daily exercise goal is higher than previous advice but not necessarily less achievable, given it can be completed throughout the day.

Fitting in an hour of exercise a day sounds especially discouraging if you have a desk job, but there are plenty of workouts you can complete before and after work. Even if it means taking a 10-minute walk during lunch, your body will thank you in the long run.

Personalized Exercise

As the start of every year, many of us promise ourselves that a certain number of times a week we will go to the gym or attend an exercise class. But finally many of us just struggle to fit exercise into our lives, or start off well and then give up. Why do we have a good plan at the beginning and fail to achieve it in the end? How can we deal with the problem?     1    

It is important to determine your motivation first. Are you mainly interested in de-stressing or in getting fitter? If your goal is relaxation, then ask yourself if you want to do it energetically.     2     If you have a calmer style, you can do something quite different. You could choose solitary exercise, such as walking the dog or doing some gardening.     3     There are quite a lot of them, such as walking and running groups, dance classes, etc. On your own, you could go horse riding or swimming, or just download fitness exercise programs and do it at home.

    4     If you have free time at the weekend, you could book some time with a personal trainer, who can come to your house, or you could meet him at the gym. If your life is not as regular, you could choose the next couple of minutes you have to try an exercise DVD, or put your running shoes on and run for any length of time.

As you see, everything counts when you are doing exercise. Whatever your lifestyle is, you will be able to have something that suits you.     5    Just sit down with a cup of tea, read this article again, and have a think about your options. Then finish the tea, get up, get going, and don’t stop.

6 . Erica and Steve Lineberry have been rock climbing since 2005. They were first introduced to it while visiting a family in Montana. Now they are at climbing centers, like Inner Peaks in Charlotte, three times a week, and on weekends they climb outdoors.

Steve said they first started climbing as part of their exercise. Years later, he lost 60 pounds. But as the couple’s interest in the sport grew, they consulted some mentors and started climbing outdoors.

Then Erica got pregnant. “Most people think that rock climbing and pregnancy don’t go very well together,” Erica said. But with lots of places to go, Erica kept climbing through her pregnancy.
