2 . Sports are as important as studies for students because they help students to stay focused and enjoy working.
Another excellent sport for students is basketball.
Volleyball is also a team sport in which two teams of six players are separated by the net. Each of the team tries forcefully to score points by grounding the ball on the other team court under organized rules.
It is generally agreed that softball developed from a game called indoor baseball, first played in Chicago in 1887. It is played with a larger ball on the smaller field.
You can include these best sports for students to play at school to keep them energetic and do better in their studies.

5 . As with every World Cup, at the 2022 FIFA World Cup in Qatar the players will be using a new ball. The last thing competitors want is for the most important piece of equipment to behave in unexpected ways in the most important tournament of the world’s most popular sport, so a lot of work goes into making sure that every new World Cup ball feels familiar to players.
Between shots on goal, free kicks and long passes, many important moments of a soccer game happen when the ball is in the air. So one of the most important characteristics of a soccer ball is how it travels through air.
As a ball moves through air, a thin layer of mostly still air called the boundary layer (边界层)surrounds some part of the ball. At low speeds this boundary layer will only cover the front half of the ball before flowing air peels (划过) away from the surface. In this case, the wake of air behind the ball is somewhat regular and is called laminar flow. When a ball is moving quickly, though, the boundary layer wraps much farther around the ball. When the flow air does eventually separate from the ball’s surface, it does so in a series of chaotic swirls (不规则气旋). This process is called turbulent flow.
When calculating how much force moving air imparts on a moving object — called drag — physicists use a term called the drag coefficient (系数). For a given speed, the higher the drag coefficient is, the more drag an object feels.
It turns out that a soccer ball’s drag coefficient is approximately 2.5 times larger for laminar flow than for turbulent flow. Though it may seem counterintuitive, roughening a ball’s surface delays the separation of the boundary layer and keeps a ball in turbulent flow longer. This fact of physics that — rougher balls feel less drag — is the reason why dimpled (坑坑洼洼的) golf balls fly much farther than they would if the balls were smooth.

9 . Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.
Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses (球场) in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf causes serious water shortage in some local areas.
There are many environment-friendly sports. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.
Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it’s free.

10 . Anyone who’s lived through middle school knows those years can be particularly challenging. Some researches show youths across the U.S. are struggling with mental health. The physical health benefits of bike riding have been well-documented. Wilson, a researcher at Loma Linda University School of Medicine, and his co-authors carried out a new study to see if taking part in a cycling program could result in measurable changes in mind for teenagers.
The study involved more than 1,200 students, ages 11 to 14. Students participated in a cycling class for at least three days a week, for a period of 6 weeks. They learned cycling safety and practicing skills outdoors while raising their heart rate and just having fun. The students completed standardized questionnaires before and after the program designed to measure their health.
“We know cycling can benefit the body. Our research shows how it benefits the mind and social relationships as well. Bike riding can be an ideal activity for adolescents because of the benefits it offers,” said Wilson.
“Cycling engages several parts of brain function. You are looking at your hearing, you’re balancing, you’re navigating and turning. Oftentimes, you’re doing it with someone else, so there’s the positive effect of company or group activity,” said Allan Reiss, a professor at Stanford University School of Medicine.
While exercise has powerful mental health benefits, it’s not universal. For example, previous research has shown that teenage girls are at higher risk of mental health problems like depression and anxiety than boys. The current study found that, while middle school girls reported increased well-being after participating in the cycling program, that increase “may just reach the kind of baseline level for male students,” Wilson said. And other aspects of healthy living are also important, noted Wilson. The study found that teenagers who didn’t limit screen time to a maximum of two hours a day, or who got less than the recommended 8.5 hours of sleep, saw less improvement in their well-being, he said.
