1 . Physical education, or gym class, isn’t required for all high school students. In some schools, it isn’t offered for some different reasons. But should high school students have physical education? The answer is certainly “yes”.

Today many people don’t do sports. But as is known to all, doing sports is very important for an adult. Teaching teens the importance of a healthy lifestyle and making fitness plans now can help teens put exercise in the first place as an adult.

High school isn’t that easy. Many students are under a lot of stress. Stress can be harmful to a student’s studies and life. Doing sports can help them deal with stress better, helping them live a happier life at school.

The American Heart Association says that 10 million kids and teens suffer from obesity (肥胖症). Teens should get 60 minutes of physical activity per day to control their weight and to help their bones get stronger.

The increase in activities that don’t get teens to move around, such as video games and computer activities, means many teens don’t get their required exercise. Physical education classes act as a public health measure to encourage activity and help teens have healthy weights.

Inactivity increases teens’ risk of developing many diseases. An active lifestyle offers a good way of protection from these health problems. As much as 75 percent of health-care spending goes toward treating medical conditions that can be hindered by lifestyle changes, according to the American College of Sports Medicine.

According to the President’s Council on Fitness, Sports and Nutrition (PCFSN), students who performed five hours of physical activity each week improved their academic (学业的) performance. Students from programs with no physical activity, who used the extra time for classroom study, did not perform better on tests than those who gave up some study time in support of physical education.

5 . In an ideal world, we would be able to devote as much time to sports as we feel we need. But in reality, with growing demands in both work and family, we can only jump at the chance for our physical exercise when we can. Making the most of that time to practice Yin Yang yoga, which mixes the dynamic and slow-paced elements of yoga, helps keep you active and relaxed.

Yin and Yang are the Taoist concepts representing a balance of opposite forces which are also interconnected. Yin is inactive, cooling, and negative, associated with the female force. Yang is   active, warming, and positive, associated with action and movement. They are complementary to one another, as one cannot exist without the other.

Yin Yang yoga is a combination (结合体) of high-energy movement which builds energy, increases strength and promotes stamina (耐力), followed by the more restful practice of Yin to give us a deeper stretch (拉伸) and calm the nervous system.

If you have a busy and active life you may feel more in Yang, so taking some cooler, slower Yin yoga practice into your routine may help you feel calmer and more balanced.

If you are practicing for an hour, divide the time in half. Warm up with sun salutations (拜日式瑜伽), continue into a dynamic flow and then move on to some standing postures. After half an hour your heart will be pumping, muscles tighten up and you are hopefully feeling energetic, but ready for a rest. Then pick five Yin postures to hold for 3-5 minutes, or even longer if you are enjoying them!

As ever with yoga, if you are a beginner or have health issues, always attend a class with a trained instructor first to guide you safely through the yoga practice and avoid injury.

6 . More scientists are exploring cellular senescence(衰老)—a state in which cells(细胞)no longer divide. Senescent cells, which build up in older bodies, have a link to age-related conditions such as dementia(痴呆) disease.

Scientists are exploring drugs that treat senescent cells. But the most promising tool against the bad effects of senescent cells, experts say, is exercise.

Today, LeBrasseur, who directs a center on aging at Mayo, says exercise is “the most promising tool that we have” for good health in late life, and its power spreads to our cells. Research suggests exercise prevents the buildup of senescent cells, helping the immune(免疫的)system clear them and fight the cell damage that can affect aging.

Last year, LeBrasseur led a study that provided the first sign in humans that exercise greatly affected senescence. It cut signs in the bloodstream of the effects of senescent cells in the body.

After a 12-week exercise program, researchers found that older adults had cut signs of senescence and improved body strength, physical ability and reported health.   A recent study collects even more facts—in animals and humans—for exercise as a treatment to fight against senescence cells.

While such studies are not well-known outside scientific circles, many older adults connect exercise with youthfulness. Farmer Mike Gale, 81, put in a track and field throwing circle on his large farm in California. He and some of his friends throw the discus(铁饼) and use other exercise equipment. “I'd like to be competing in my 90s,” Gale says. “Why not?”

95-year-old Richard Soller says exercise keeps him fit enough to deal with what comes his way—including the discovery that his wife of 62 years had developed dementia. The two sometimes walk the streets of their neighborhood together, holding hands. “Do as much as you can,” he says. “That should be the goal for anyone to stay healthy.”

8 . Teenagers’ fitness is now a major concern, to which 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 scientist Dr.Helen Lopez offers the following advice to teenagers: “Firstly, you need to find out your present level of fitness. Then you can design a programme that will help you become healthier.”

Dr Lopez suggests that 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 Dr Lopez, overweight teenagers should keep active 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 up 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,” said Dr Lopez. The same principle applies to active teenagers.

Dr Lopez suggests one hour a week or more on running and other forms of intensive exercise, together with fifteen minutes a day spent on stretching and bending activities. “These are really important in order to prevent injuries,” Dr Lopez said. Some weight-training and other body-strengthening exercises could also be planned in the programme in order to increase the personˈs strength.

10 . Health and fitness help a person live a good and healthy life. Often due to various pressures, we tend to ignore our health. This makes our body suffer and we will catch other diseases. It is the fitness level of our body that helps us fight these diseases.

Health and fitness are interrelated to each other. We need to be fit to have a healthy body.

Similarly, if we are healthy we shall naturally be attracted towards maintaining the fitness of our body. Health is the state of our body at a given time. We may not have any disease but still have a weak body, which is ready to be targeted by viruses. For instance, we may have a tendency to catch a cold easily. This does not definitely mean that we are not healthy. It means the fitness level is not in accordance with our age and the climatic conditions we live in.

It is important for everyone to devote some time to health and fitness. There are some activities which everyone should do in our life. For instance, we must exercise daily regardless of our age and working style. There are different levels of exercises for different age groups and we must do them according to our own health and age.

Additionally, it is important to relax our body. We should have at least six to eight hours of sleep every day. It helps in improving our immune(免疫) system and protects us against diseases. It also helps in keeping us calm and relaxes our mind. This, in turn, gives us new goals of health and fitness.
