2 . In a world ruled by hard exercise and complex fitness programs, the simple act of walking is often ignored(忽略).     1     It offers physical and mental benefits that lead to total happiness.

Heart Health and Weight Management

Walking is light heart exercise that helps improve heart health by increasing blood circulation(循环).     2     Besides, regular quick walking supports in weight management by burning calories and improving digestion(消化), making it an excellent choice for those looking to throw away pounds or keep a healthy weight.

Pressure Drop and Clear Mind

Taking a relaxing walk or quick walk has been shown to give off endorphins, the body’s natural ”feel-good” materials. This leads to lower pressure levels, improved feelings, and improved mental health. Walking outdoors in nature or in a peaceful environment can provide a refreshing escape from the daily tasks.     3    

Joint(关节)Health and Free Movement

Unlike active sports, walking is soft on the joints, making it a perfect choice for people of all ages and fitness levels.     4     At the same time, it also raises the ability to move freely and easily. Walking regularly can be particularly beneficial to those recovering from pain or looking to prevent problems with joints.

Social Communication and Connection

    5     Walking clubs, group climbs, or even simple walking with a friend or family member can provide an opportunity to connect, share experiences, and create lasting memories while at the same time bringing the physical benefits.

6 . Pleasanton Partnerships in Education Foundation (PPIE) was started in 1987 to raise money by organizing running events for local schools. Based in Pleasanton, California, a suburb of San Francisco, the non-profit organization recently hosted a family-focused fitness event for the community. “Our event helps to bring the community together,” said Mindy Louie, events and outreach manager for PPIE. “We have more than 3,000 participants, hard-working volunteers and viewers.”

This year’s fitness event took place on April 30 at the Alameda County Fairgrounds. It featured races of two miles, five kilometers and ten kilometers. A new Kids Challenge consisted of a quarter-mile run to encourage younger children to participate. When asked to describe the run, 11-year-old Jeremy Louie said, “Fun, exciting and enjoyable.” Jeremy added that he was happy to help support his school.

PPIE supports all 15 schools in the Pleasanton Unified School District, which include more than 14, 500 students and 800 teachers and staff. The nonprofit organization tries to fund programs affected by budget cuts, while encouraging fitness and athleticism. To date, the PPIE has raised over $1 million for the school district.

A local runners’ group called the BURN Youth Development (B. Y. D.) participated in the fundraising. The B.Y.D. has since grown to more than 100 youth members, 30 of whom ran in April’s PPIE event. Jerry Wu, the group’s founder and lead coach, explained that the B.Y.D. was born to keep kids running. “Watching them running strongly and happily makes me smile every time,” Jerry said.

Jerry encourages teamwork and teaches the students valuable running techniques. As a B.Y.D. member, Ollie Gu, an eighth grader, was one of the top finishers in the ten-kilometer run. He completed the race in 40 minutes and 46 seconds and won first place in the 12-to-15 year-old age group. “The race was extremely rewarding,” Ollie said. “I’m looking forward to it next year.”

7 . A small study out of Skidmore College examined the advantages of morning vs, evening exercise for both women and men. Paul, professor for health at Skidmore, led the study.

“We had the groups divided into evening and morning groups,” he says. “We found women and men answered differently to different types of exercise depending on the time of the day, which surprised us.”

The study showed that for women who want to lower blood pressure (血压), the risk of heart disease or reduce fat, morning exercise works best. Those women hoping for upper body muscle (肌肉) gains or mood (心情) improvement should consider evening exercise. For the men, the findings were somewhat different: Evening exercise lowers blood pressure, the risk of heart disease, and feelings of tiredness. But similar to women, they burn more fat with morning exercise.

“For many people, the best time to exercise will depend on their chronotype,” says Heisz, author of Move the Body, Heal the Mind.

“Chronotype is your body’s natural habit to sleep at a certain time—it’s what decides whether you’re a night owl or an early bird. For the 25% of the population that considers themselves a night owl, getting both enough sleep and enough exercise can be difficult,” adds Heisz.

He continues, “Sleep—which provides your body the necessary time to recover (恢复) and make gains from exercise—should always be the first choice. When it comes to exercise, regardless of research on the advantages of certain exercises at particular times of the day, your results will not be good if it doesn’t allow enough time for sleep.”

8 . You start by running around the school track three times to warm up. This is followed by exercises or long jump for the girls and football or basketball for the boys. That is an average 45 -minute PE class— but do you really enjoy it?

For students at the Second High School Attached to Beijing Normal University, sports classes have experienced a welcome change. Senior 2 students now learn the traditional Chinese martial art of sword-fighting (中国剑术), making PE the most popular lesson on the timetable. “The classes used to be boring as we just did the same things again and again,” said Xiao Tong. “But now PE classes are such fun. Sword-fighting is so cool.” His classmate Wei Jie agrees. “As well as being fun, we learn about traditional Chinese culture,” she said. The usual morning exercises performed to music on the school playground have been replaced by kicking and punching practice (搏击操) to a pop music by Zheng Xiuwen. “We didn't pay much attention when we heard the old music,” Xiao explained, “But when Zheng's music is played, we get excited.” Mao Min, the PE teacher who introduced the changes, is pleased that the students now enjoy sports lessons more. “The classes encourage healthy lifestyles and I am always looking for creative ways to keep the students active,” he said. Schools offer activities according to what sports facilities (设备) they have. For example, students at the Experimental High School Attached to Beijing Normal University can choose to learn swimming, taekwondo (跆拳道) or volleyball. “I take my volleyball very seriously so I keep fit by playing it,” said Senior 2 student Zhang Zheng. “Students only try hard in sports that interest them.”

9 . What do classrooms, computer desks, cafeterias(自助食堂), and libraries have in common? That’s the places where students spend so much of their time.Although hours of studying burn mental energy，both your body and mind need physical exercise to function efficiently.

The importance of exercise is nothing new.Thomas Jefferson once wrote that to be successful in academic studies, a person should spend two hours on exercise every day, for health must not be sacrificed(牺牲) for learning.A strong body makes the mind strong.

It turns out Jefferson was on to something. A study by researchers at Tufts University found that students who said they exercised at least 3 days a week were more likely to report a better state of physical health and greater happiness than those who didn’t exercise. This and other evidence suggest that the real benefits of exercise may not come right after a workout but from a longer commitment to regular activity.

But experts today do not demand 2 hours of daily exercise.The U. S. Department of Health and Human Services recommends that people get at least 60 minutes of physical activity most days of the week.

Walking，jogging and swimming are easy ways to increase your heart rate and improve health.Exercise can also help lower blood pressure and reduce stress. For women, exercise that makes the body and bones bear weight—like walking or running—may reduce the risk of osteoporosis(骨质疏松) later in life.

You’ll likely discover another benefit of exercise as well: greater self-confidence.This may make it easier for you to participate in class and help you perform well in academic and social situations.

10 . Most kinds of physical exercises are beneficial for remaining healthy, but a lot of people prefer running over other forms of physical exercises. This may be because running does not require expertise and specialized equipment.     1     Some runners choose to run for the adrenaline (肾上腺素) and others choose it for the health benefits.

Running is a weight-bearing exercise.     2     It is especially helpful for young children and teenagers whose bones have not completely developed. Running is also helpful in improving joint stability (关节稳定性). It is also considered a great way of losing fat and keeping a healthy weight.

    3     A lot of runners experience a sense of excitement and happiness after a run. Running releases endorphins (释放内啡肽) in your brain, which can improve mood (心情). Endorphins also naturally help manage stress.     4    

While running is considered a great exercise, it should not be the only form of exercise that you perform. Running regularly, especially with improper running shoes, could increase the risk of pain in the knees. It could also cause damage (损伤) to the knee joints.     5     It can achieve a balance of strength between the upper and lower parts of the body.
