Do we have a movement signature?
As humans, we have several qualities that separate us from one another, such as our fingerprints.
According to a recent study, each person has a unique movement signature (鲜明特征). Depending on the person, these differences can be subtle or pronounced.
For the study, scientists attached electrodes (电极) to muscles in the legs of volunteers. The volunteer were then asked to perform activities such as walking on walking machines and riding stationary bikes (健身车), which were adjusted according to each person's physical appearance in order to make sure everyone was judged using the same standards.
Scientists fed the information to a computer along with the volunteer's name. Next, the computer was fed information without the user's name and it could identity the person correctly 99% of the time. The outcomes of the study showed that each of us does have something unique about our general movements.
Since this is just a pilot study, scientists will do more tests to see if the signature changes with age and weight changes. But with a deeper understanding of the science of movement, doctors could possibly develop more intricate prosthetics (复杂精细的假肢). Whether that's cool or frightening is up to you to decide.
A. How could this study be of use to scientists?
B. What do you think of the findings of the study?
C. Volunteers are expected to write a report on the activities.

A. Get good running shoes. B. Usually, there are warning signs. C. Running may also help you live longer. D. These exercises are easier on the body. E. Muscles and joints (关节) need time to recover. F. As advertisements for the running shoes Nike say, "Just do it." G. Here are five ideas to reduce the risk of injury. |
Five tips for safe running
We all know that exercise is good for our health. But some kinds of exercise may be better than others. Running, for example, may help to protect against heart disease and other health problems.
Running is good exercise, but it can be hard on the body. {#blank#}1{#/blank#}
Take it easy. Do not run too much, too soon or too fast. Most people get running injuries when they push themselves too bad. The body needs time to get used to increases in distance or speed. {#blank#}2{#/blank#}
Listen to your body. Most running injuries do not come unexpectedly. {#blank#}3{#/blank#} They may include body aches, sore muscles (肌肉酸痛) and pain that does not go away.
{#blank#}4{#/blank#} There is no single best shoe for every runner. You should find the shoes that offer the best fit and support for your feet. More importantly, you should replace your shoes every 500 to 800 kilometers.
Take good notes. Take time after each run to write down what you did and how you felt. Look for patterns, things that happen over and over again. These notes will help you find the best exercise for you.
Cross train. As we said earlier, running is hard on your body. So physical fitness experts suggest some form of cross training to improve muscle balance and to help you stay injury free. They say swimming, yoga, and riding a bicycle are good exercises to combine with running. {#blank#}5{#/blank#}
