2 . Physical education, or PE, 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 essential for an adult. Teaching teens the significance of a healthy lifestyle and making fitness plans now can help teens make exercise their priority 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. 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 computer games, means many teens don’t get their required exercise. PE classes act as a public health measureto encourage physical activities and help teens have healthy weights.

Not doing sports increases teens’ hazard 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 prevented 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 activities each week improved their academic 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.

10 . Many know the importance of properly warming up and preparing to exercise, but experts say that including a cool down routine is just as important. According to the Mayo Clinic, cooling down allows for your body to recover and return to its normal, pre-exercise state.

Though cooling down isn’t proven to reduce muscle stiffness (僵硬) or pain, it can prevent dizziness and allow your heart rate and breathing to ease back to a normal rate, Harvard Medical School reports. Phyllis Mammarelli, a personal trainer at the Shenango Valley YMCA in Sharon, Pennsylvania, works with each of her clients on a cool down routine as she says it’s a beneficial part of exercising.

“Cooling down allows your body to gradually return to a low-intensity activity level, slowly reducing your respiratory (呼吸的) and heart rate until it’s equalized and back to normal,” she says.

Skipping the recovery phase of a workout isn’t proven to be harmful to your body, but Mammarelli warns that without cooling down, the body will take longer to return back to the low-intensity activity level you began your workout with.

There are also non-threatening side effects that could occur as a result of forgoing a cool down. Mammarelli warns that blood can gather or pool in your lower extremities (四肢) and lead to dizziness and fainting. Other side effects include your muscle pain and stiffness, which can occur 24-28 hours after your workout. These side effects are mostly seen in the elderly or those with cardiovascular (心血管的) disease and can be eased by warming up and cooling down.

Allow five to 10 minutes at the conclusion of your workout for a cool-down routine. During this period, continue your workout session, but at a much-reduced rate. If you’re pressed for time during your works or unsure how to allow your body to recover, Mammarelli suggests stretching muscles in a pain-free range of motion.

Adding a few additional minutes to your workout for cooling down may seem like an inconvenience, but the benefits outweigh the cost of finding extra time in your schedule.
