The history of roller skating

Roller skating started at 1760 and was invented by Joseph Meilan of Belgium. It took James Pliem Puton of the United States 100 years to develop roller skates into four wheels. It was not until 1884 that Richard Hudson of the United States installed roller skates with ball bearings, which developed into what it is now. 1884, the national roller skating championship was held for the first time in Britain. At the beginning of the 20th century, roller skating was widely carried out in America and Europe. 19 10, roller skating competitions began to appear in Europe. Britain built the world's largest roller skating rink in 1908. 1924, the International Roller Skating Federation was established with its headquarters in Barcelona, Spain. At present, more than 60 countries and regions around the world have joined the association. Roller skating was introduced to China as an entertainment event at the end of 19, but it developed as a sports event in the early 1980s. As a sport, roller skating is still in the development stage in China, but as a leisure sport, it has already spread all over the country. Roller skating is a kind of sport that shows one's physical strength and grace on the road with the help of semi-mechanical roller skates, which is deeply loved by teenagers.

Roller skating classification

Roller skating is a leisure sport, but it is also a competitive event. With its continuous improvement, a number of roller skating events have been formed, and roller skating has appeared in this Olympic Games. Modern roller skating is divided into three categories: speed roller skating, figure roller skating and roller skating ball;

① Speed roller skating. The events with single-row and double-row roller skates as the competition tools are divided into field races and road races. The official competition distances of track events in the World Championships are men's1000m, 5000m,1000m and 20000m, and women's 500m, 3000m and 5000m. The road race includes the women's 2 1 km half marathon and the men's 42 km marathon. The track is basin-shaped, like a bicycle field.

② Figure skating. It is divided into figure skating, free skating, pair skating and pair dancing. The competition will be held in a venue not less than 50 meters long and 25 meters wide. Each team can take part in 3 people in each competition, male and female 12 people. According to the difficulty of the movement and the beauty of the dance, the winner is decided.

③ Roller skating. It looks like a combination of ice hockey and hockey, and the play is similar to ice hockey. There are 5 players in each team, of whom 1 is the goalkeeper. Athletes wear roller skates and hold wooden clubs with a length of 91~14cm, and compete on a rectangular hard ground court made of cement or granite with a length of 22m and a width of12.35m.. Players can pass the ball and dribble it into the opponent's goal through cooperation, and score 1 point. The team that scores more points is the winner. The goal is 1.05 m high and 1.54 m wide, and placed between the two ends of the court. The ball used in the game is like baseball, weighing155.925g. Each game is divided into two rounds, each round is 20 minutes.

In addition, there are: extreme sports and skills: using U-shaped platform and slider to perform all kinds of thrilling and complicated skills, which are divided into street race and semi-tube race, which is also the most attractive one in roller skating competition.

Leisure roller skating: for the purpose of leisure and fitness, wear roller skates and freely perform various skating methods in various venues and environments. The most important activity is to "brush the street", slide slowly, browse the street view, bathe in the sun, breathe fresh air and relax.

Advantages of roller skating

Entertainment: Roller skating is very entertaining and interesting. Through this sport, people can get rid of the usual stressful and heavy study and work, so as to achieve the purpose of physical and mental relaxation.

Fitness: Roller skating is a systemic exercise, which can promote the improvement of cardiovascular and cerebrovascular system and respiratory system functions and strengthen metabolism, enhance the strength of muscles such as arms, legs, waist and abdomen and the flexibility of various joints of the body, and is especially suitable for people to master balance.

Instrumentality: In addition to the above two features, roller skating has another feature that many sports do not have, that is, it can be used as a means of transportation. In general, roller skating can become a means of transportation on a flat road. In today's increasingly crowded traffic, roller skating is a popular and fashionable means of transportation. However, when taxiing on the street where cars are coming and going, we must pay attention to traffic safety.

Roller skating equipment

roller skates

Body: The shell of roller skates can prevent external impact and protect feet. Generally, shoes with buckles are more convenient to wear; Those who tie shoelaces will be closer to their feet, but it will be more troublesome to put them on and take them off. Generally, better roller skates are designed with straps and buckles. Ordinary roller skates have inner boots, which can cushion the friction between the foot and the shoe shell, thus protecting the foot and making the skin not easy to scratch and blister. A good shoe body should be strong enough, the sponge should be thick enough and the density should be high enough.

Underframe: Underframe is the structure connecting the wheel and the shoe shell. The toughness of the underframe system is the main factor that determines the service life of roller skates. There are usually different types of underframe designs, some thicker and some thinner. The underframe is usually equipped with four wheels, but there are also small underframes with three wheels and speed shoes with five wheels. Aluminum alloy chassis is better, because aluminum alloy chassis is hard and not easy to deform, but it is more expensive.

Wheels: Wheels must be highly elastic, not plastic. It is best to choose polyester materials, that is, rubber tires, which are suitable for various venues and conditions. Rubber wheels are soft and elastic, while plastic wheels are hard. You can try knocking on the ground to feel the sound, and you will find that the sound of plastic wheels is much sharper and easy to slip. Some roller skates are equipped with hexagon wrenches to tighten the wheels.

Size: In addition to the quality of each part of the shoe, we should also pay attention to the size of the foot. Experts suggest that when buying the size you usually wear, you must wear it yourself. Must not be too big, as long as it doesn't feel tight. Generally, the shoelaces are tied. When the calf is vertical to the ground, the distance between the front end of the foot and the inner sleeve of the shoe is as much as half a thumb (hand). Too big shoes are unsafe.

You can buy unprofessional pulleys at the beginning. Generally speaking, novices should also practice basic movements such as sliding, turning and braking on the road. Non-professional pulleys can meet these requirements, and the price is relatively cheap, one or two hundred yuan can be bought. But when you start to learn all kinds of extreme movements, you must buy professional-grade pulleys, because those difficult movements are not acceptable to ordinary pulleys.

Professional roller skates and non-professional roller skates

There are four main differences between professional pulleys and non-professional pulleys. One is the wheel of the sole. The wheels of non-professional pulleys are hollow, with regular holes on the shaft, and the bottom of the pulley is often round, while professional pulleys are the opposite. The wheel is solid and the bottom of the wheel is flat, so that it can bear greater impact and complete many difficult jumping movements. The second is whether there is a groove in the middle of the sole. This groove is used when the sliding bar is embedded in the iron bar. Professional pulleys must have grooves. The third is the "beam" of the sole. The thick beam is a professional pulley, and the weak beam is a non-professional pulley. Be careful not to jump in these shoes, or they will break. Finally, the weight of the shoes. Professional-grade pulleys are heavy because many parts are solid and made of very strong materials.

Protective equipment

Protective gear is the most easily overlooked but important equipment, including helmet, elbow pads, wrist pads and knee pads. Many people don't want to wear protective gear for fear of being considered delicate or troublesome, but almost all people who practice roller skating for a long time believe that wearing protective gear can not only protect themselves, but also maintain a good practice mentality.

Common sense of roller skates maintenance

Don't pass on the grass and mud, because doing so will make the gravel wear the wheels of roller skates, and the sand will run into the bearings and need to be cleaned frequently.

Try not to play roller skating on rainy days, because water will rust the bearings.

When the bearing rusts, you need to buy a small bottle of lubricating oil (gasoline or engine oil), 200 ml is enough. Soak the bearing for three or four days, and the rust can be removed.

safety measure

1. Before practicing roller skating, you should be prepared for activities, especially the joints and ligaments of your wrists and lower limbs.

2. If possible, wear some protective equipment, such as wrist pads, elbow pads, knee pads, roller skating helmets, etc. Now many sporting goods stores have this kind of special protective gear for roller skating.

3. Check the fastening parts such as screws of roller skates before practice, so as to avoid injury caused by problems with roller skates when sliding.

4. Beginners should practice in the beginner's field or within the prescribed scope, or try to practice in a place with few people, and don't skate at will. The first time you learn roller skating, it is best to have a skilled skating partner or psychological counselor for counseling.

5. It is forbidden to do dangerous or obstructing actions, especially in crowded public skating rinks, such as several people skating hand in hand, retrograde on the speed skating track or in the direction of skating with everyone, jumping, jumping, chasing and flapping, and stopping suddenly. Things that are both harmful and prone to danger. If you slide on the expressway, you should pay more attention to traffic safety, and it is best to practice in places with few people and cars.

6. It is inevitable to wrestle when learning roller skating, but you should learn to protect yourself when wrestling. The method is: when you want to fall forward or sideways, you should take the initiative to kneel down and use your hands to cushion the ground to reduce the power of falling; When you want to fall backwards, you should also take the initiative to kneel down, lower your center of gravity, try to let your hips sit down first, and pay attention to protecting your coccyx, while lowering your head to avoid falling backwards. When you fall, try to avoid holding the ground with straight arms and one hand, which is easy to damage your wrist.

7. People with serious diseases (such as heart disease and high blood pressure). ) It is not appropriate to participate in intense roller skating activities, and you can exercise slowly at most. In addition, people who drink alcohol and are overtired should not take part in roller skating activities.
