山东 路冬梅

青少年的健康问题近期备受关注，科学家也已经给出相关建议，让我们一起到文章中一探究竟。

Teenagers' fitness is now a major concern and physical exercise is very important. It reduces stress and improves fitness. Exercise makes your body strong and helps you to keep the right body weight. Sports scientists offer the following advice to teenagers: First, find out your present level of fitness. Then you can design a programme that will help you become healthier.

There are three levels of fitness that need a change of lifestyle. “Overweight” means that the person gets very little exercise and often has a serious weight problem. “Inactive'' means that the person does not join in many physical activities, but is not seriously overweight. “Active” refers to people who take part in sports and other physical activities, but do not have a high fitness level.

According to experts, overweight teenagers should work out to keep healthy. Ride a bike, play volleyball or basketball for a while, and go for a twenty-minute walk each day. All these will help to burn calories. Inactive teenagers should do similar activities, but add some bending and stretching exercises, such as push-ups and sit-ups, starting with twenty of each a day. Inactive people can take a little more exercise than overweight people because their bodies are stronger. The same rule is also suitable for active teenagers.

Experts also suggest one hour a week or more on running and other forms of intensive exercises,together with fifteen minutes a day spent on stretching and bending activities. They are really important in order to prevent injuries. Some weight-training and other body-strengthening exercises could also be planned in the programme in order to increase people's strength.
