4 . Five tips for safe running

We all know that exercise is good for our health. But some kinds of exercise may be better than others. Running, for example, may help to protect against heart disease and other health problems.

Running is good exercise, but it can be hard on the body.     1    

Take it easy. Do not run too much, too soon or too fast. Most people get running injuries (受伤) when they push themselves too bad. The body needs time to get used to increase in distance or speed.     2    

Listen to your body. Most running injuries do not come unexpectedly (意外地).     3    

They may include body aches, sore muscles (肌肉) and pain that does not go away.

    4     There is no single best shoe for every runner. You should find the shoe that offers the best fit and support for your feet. More importantly, you should replace your shoes every 500 to 800 kilometers.

Take good notes. Take time after each run to write down what you did and how you felt. Look for patterns, things that happen over again. These notes will help you find the best exercise for you.

Cross train. As we said earlier, running is hard on your body. So physical fitness experts suggest some form of cross training to improve muscle balance and to help you stay injury free. They say, besides running, swimming, yoga, and riding a bicycle are good exercises.     5

7 . Recently, the organizers of the 2024 Paris Olympics have suggested that breakdancing be included in 2024, making it closer to becoming an Olympic sport. The other 3 sports—surfing, skateboarding and sport climbing—all made debuts in the 2020 Tokyo Olympics. That is to say, audience watched these three sports as Olympic events for the first time.

The organizers stressed that four sports had been chosen since they would reflect the city’s identity and help take the Olympics to the street. They added that the purposes were to deliver a Games that was able to keep up with the times and encourage new audience and attract young people. Breakdancing is a typical example which can be played without the limitations of time and places in urban and other environments.

As one of the sports at the Young Olympic Games in Buenos Aires in 2018, breakdancing now could see its popularity greatly raised. But the International Olympic Committee (IOC) needs to approve the French suggestion before it can be formally added to the 2024 Paris Olympics sports programme.

With new IOC rules first introduced to the 2020 Tokyo Olympics, Host cities can select sports and propose them for inclusion in those Games if they are popular in that country and add to the Game’s appeal.

Antonio Espinos Ortueta, the president of the World Karate Federation said, “Our sport has grown rapidly over the last years. We believe that we have met all the requirements and that we have the perfect conditions to be added to the sports programme. However, we have learned today that we still haven’t had the chance to prove our value as an Olympic sport.”

8 . Canyoning

The sports of canyoning (蹦谷) explore the high-energy environment where water meets rock on the coast. Protected by wetsuits and helmets, people jump from cliffs and waterfalls and discover caves that would not normally be arrived at.

It was first done in the U.K. by TYF Adventure (01437 721611, www.tyf.com) and several thousand people jump from the cliffs near St David’s each year. A half day canyoning trip costs ￡50 (￡30 for children under 16).

Diving

Diving is not popular with British people. The difficulties of wild waters are greater because the water is colder and not clear enough, but the coasts of Cornwall, Wales and Scotland have some of the best diving in the world.

The British Sub Aqua Club (0870 112 9133, www.bsac.com) and the Professional Association of Diving Instructors (01580 819688, www.padi.com) run courses teaching the important skills.

Surfing

The best surfing places in the UK are on the southwest coast where it is warmer, especially in Cornwall. The best time of year to surf in the UK is late summer and autumn.

The British Surfing Association (01479 861256, www.britsurf.co.uk) has a list of famous surf schools around the country.

Rock climbing

The most popular natural rocks in Britain include the Peak District, the Lake District, while large areas of Scotland are a climber’s ideal place. Climbing courses and climbing walls can be found on the website of the British Mountaineering Council (0870 010 4878, www.thebmc.co.uk).

10 . All over the world people enjoy sports. Sports help to keep people healthy and happy, and to live longer. Many people like to watch others play games. They buy tickets or turn on their TVs to watch the games. Often they get very excited when “their” player or team wins.

Some sports are so interesting that people everywhere go in for them. Football, for example, has spread around the world. Swimming is popular in all countries near the sea or in those with many rivers. What fun it is to jump into a pool or lake, whether in China, Egypt or Italy! And think of people in cold countries. Think how many people love to skate or ski in Japan, Norway or Canada. Some sports or games go back thousands of years, like running or jumping. Chinese wushu, for example, has a very long history. But basketball and volleyball are rather new. They are about one hundred years old. People are inventing new sports or games all the time. Water－skiing is one of the newest in the family of sports.

People from different countries often become good friends after a game together. Sports help them to understand each other. One learns to fight hard but fight fair, to win without pride and to lose with grace．
