International Program Classification of Roller Skating

Figure skating is the root of all ornamental roller skating programs, ornamental roller skating culture are developed from figure skating, figure skating sports competition programs. Including male and female single skating; male and female pair skating; dance (male and female pair) three. Single skating including the provision of graphics

Figure skating from figure skating (Figure Skating) is the Asian Games (Asian Games) official competition. Skaters wear skates with four side-by-side wheels on the soles of their feet, skate on a wooden floor under their own power, and perform a pre-programmed program based on technical maneuvers, which are evaluated by a panel of judges for scoring and ranking. Figure skating competitions are categorized into different levels (from beginner to Olympic) and scales (from regional to national to international) according to the level and scope of the competitors. Figure skating was founded in 1892 by the International Skating Union (ISU), the world's governing body for figure skating, which is responsible for formulating rules and judging international competitions. Since inland ice skating is not as convenient as ice skating in colder regions, the sport continued to be developed by using pairs of roller skates instead of ice skates, and became an independent event at the international level. It became an independent event at the international level. Figure skating and figure skating are like twin sisters, except that one uses four-wheeled roller skates and the other uses ice skates; one makes beautiful moves on a wooden floor and the other skates on ice. But the two programs, which look especially similar, have many differences. Pairs skating includes short and long programs. Dance includes regulation, choreographed and free dance Figure skating, in fact, was first developed as a stand-alone sport in order to be able to train figure skaters without ice, with the sports equipment of double roller skates. The competition takes place on a field no less than 50 meters long and 25 meters wide. The winner is determined by scoring according to the degree of difficulty of the maneuver and the grace of the dance.

8. Both Flat Fancy and Fancy Brake are sub-programs of FreeStyle Roller Derby.

Flat Fancy includes Fancy Brakes and Speed Brakes. The Emperor of World Roller Skating, St. Sebastien Laffargue, or SEBA for short, is arguably the originator of Slalom. The Slalom was inspired by obstacle skating, and with the addition of elements unique to roller skating, it has slowly evolved into what it is today.

Recreational roller skating is commonly referred to as street skating. It is a form of roller skating where you wear roller skates and stroll outdoors to feel the ease, pleasure and freedom that roller skating brings to people. It is mainly for the purpose of leisure and fitness, relaxation of self, soothing mood.

FSK is a special form of roller skating derived from the mixture of various forms of roller skating. A collection of leisure, street brushing, fancy brakes, fancy jumps, spinning and other elements. It is roughly divided into two types of play: wild street and field. Wild street is in the process of brushing the street into the speed drop, fancy jumps and other forms of skating, so that the charm of the wild street is endless. Field FSK is mainly in a certain field fancy stop, fancy rotation, of course, there are other forms of roller skating integration into. A relatively exciting form of roller skating similar to speed skating. Generally choose to carry out in the steeper highway or mountain road. After wearing a good full set of protective gear, downhill by the tilt of the road surface to give power, the human body free fall, feel the excitement of the wind and electricity.

Downhill Roller Skating (Down Hill Roller Skating), divided into two groups, double-row roller skating group and single-row roller skating group, and derivative projects obstacles downhill and downhill roller skating clothes, is a very representative of extreme sports sports, the use of roller skates are special roller skates, the two groups have their own championships, but can also be used and downhill skateboarding, downhill tricycle, downhill tricycle, and downhill skateboarding, downhill tricycle, downhill tricycle, and downhill skateboarding. The two divisions have their own championships, but can also be mixed with downhill skateboarding, downhill tricycling, and downhill dh biking. Roller derby is regarded as the pinnacle of the roller derby program. It is worth noting that double-row roller derby uses a real round ball, while single-row roller derby uses a ball and.

Roller derby is a sport that does not involve direct contact with the ball. Players play wearing either double or single-row skates. There are four field players and a goalie on each side of the game. The sport originated in England in 1896. Although roller field hockey originated in England, the sport is more popular in Latin-speaking countries such as Spain, Portugal and Argentina. These countries have professional clubs such as Barcelona, Porto and La Coru?a, where more than 5,000 professional players play the sport. Roller derby is recognized by the International Olympic Committee as a world event.

In 1992, Roller Derby was the only Olympic sport to play at the Barcelona Olympics, in the double-row category! Double skating combined with Locking popping Hiphop Breaking Free style and other dances to become a new trend of street culture in the United States

jamskating in the 1970s in the United States with the rise of disco and prevalent, so once also called roller disco.

With the disco boom gradually receding in the 1980s, jamskating began to join elements such as breakdancing, and then with the rise of street culture in the United States, jamskating gradually joined the street dance (hip-hop, breaking, popping, locking, jazz, house.), krump, reggae, c-walk, etc.), Latin dance, modern dance, ballet and other types of dance.

At the same time, due to the birth of other fancy new sports, jamskating at the same time should be added to the Chinese martial arts, Indian yoga, artistic gymnastics, Brazilian war dance, Melbourne trampoline, parkour, roller skating (figure skating, flat flower skating, wheel dance, etc.) and other types of ornamental talent fusion of integration and gradually evolved into the 21st century today's jamskating.

JB skating

In the development of today's mature jamskating, the original style has also been retained, the bias control wheel style, still using disco dance music JB skating is still the majority of jamskating players love the style, the use of sports equipment, or by the original figure skating regulation graphics special shoes

Basic Wheel Dance Fancy Moves

Because jamskating incorporates too many talent programs, plus players from various countries continue to innovate, so there are endless fancy moves, countless.

It can be mainly divided into three categories:

1. Basic footwork: including kick (kick), crazy leg (crazy leg), iceberg (iceberg), etc.

2. Basic modeling: including freeze (freeze), dragonfly pointing to the water, falling eagle, etc.

3. Basic skills: including spinning, jumping, inverted and so on.

Player Profile

Players who play jamskating are called jamskater.

Playing jamskating mainly involves hip-hop music. Because jamskating belongs to a new inclusive sports program, regardless of age, regardless of men and women of all ages, as long as the hobby can enjoy the fun of it, has become a popular popular sport in the United States, parks, plazas, skating rinks can be seen in the jamskater's figure, in addition to the world will be held every year jamskating competition, the amount of money is high!

Competition

Methods of competition

The jamskating competitions are mainly divided into Performance and Battle.

The performance tournaments are divided into: single, double, triple, and team tournaments, (sometimes subdivided into men's tournaments, women's tournaments, and children's tournaments).

Perform a piece of music with their respective fancy moves.

Battle matches are divided into: 1 vs. 1, 2 vs. 2, 3 vs. 3, and group vs. group.

Split into two sides, each show their own fancy moves, the referee extends the left hand or right hand to determine which side wins, the number of judges is odd. jamskating in various countries due to the international popularity of Breaksk8, a young inspirational team, the number of fans continues to increase, jamskating also began to popularize in various countries around the world, which also directly prompted the emergence of various players in jamskating sport. The jamskating movement has seen the emergence of various player styles.

And in China, because of the program of Tian Tian Xiang Shang let a lot of like out of the new skating players recognize breaksk8, also began to enter the jamskating circle, more and more men and women began to turn the old style of roller skating play into a new style of jamskating fancy skating style Roller skating blocking race and confrontation contest (Roller Derby) Development: by the 1950s and 1960s, roller skating was the most popular sport in the world, and it was the most popular sport in the world. By the 1950s and 1960s, roller derby had broken out of the United States and was popular in Europe, Australia and other Western countries. The sport had a reputation for wild and aggressive maneuvers, and players became increasingly confrontational. in the early 1980s, as the economy slowed down and sports declined, roller derby experienced several ups and downs. Roller derby evolved: after 2000, the sport entered a mid-career boom, with all-female roller derby leagues in almost every state and a strong grassroots flavor: almost all roller derby clubs were formed by enthusiasts on their own initiative, with players as athletes as well as owners and employees. Both preserve the direct and rough physical confrontation of roller derby from the last century and, in the uniforms, add elements of punk fashion preferred by modern women.

The rules of the game: The playing field is a circular rink, and each team sends five players onto the ice, including three blockers, one pivoter, and one scoring forward. The first whistle sounded, interceptors and curbing players quickly skated out; the second whistle sounded again, located in the team's last forward skating, as long as more than the other side of the curbing players can become the leading forward. The more players you pass, the higher the score. Every two minutes for a blocking, each blocking after the calculation of the forward score. It is the most common in domestic rinks, shaped like a figure shoe, but the difference is that the deceleration rubber is not as adjustable as the point of ice, and the wheel frame is usually made of yellow nylon.

Double skates are mainly composed of upper shoes, axle frame, bearings and wheels. The picture below is a breakdown of this type of skate. The axle frame is the core component, and all components are connected through the axle frame to form a single unit.

Double shoes from the upper shoe, down to the bottom plate to the tripod between the shock absorption, for tilt steering, the bottom plate plus tripod is called the wheel frame, the wheel frame in front of a bit of ice/brake, the wheels, although wide, but increase the hardness of the speed, increase the width of the grip can be improved, in these prerequisites at the same time there are shock absorbers and comfortable upper shoes can be neutralized and the hard wheels to bring the feeling of vibration, the double shoes is a kind of Precision machinery

The main items of double skating are figure skating, speed skating, roller skating ball and free skating. They are also used outdoors for parades and team blocking games. The following discussion focuses on speed skating equipment for speed skating programs. Speed skating skates have a short upper shoe so that the athlete can squat deeper to accomplish the skating motion better. Because the wheel diameter is small, so the stirrup ice angle of attack is small, so the low shoes can also meet the requirements. Upper shoes common materials for plastic and cushioning, artificial leather and leather and other materials, high-grade shoes basically use cowhide bottom and use cowhide or artificial leather material production upper shoes, lightweight and comfortable. Well-known manufacturer Bont launched a carbon fiber and fiberglass for the outer surface of the cowhide double shoes

Bearing

Each wheel with 2 bearings, model 608 or 688, the same as the single row of roller skates, technical standards and maintenance methods are the same.  The axle frame of double-row shoes is completely different from that of single-row shoes, the basic structure is a large substrate with numerous mounting holes, some of which are used for the connection of the axle frame through the upper shoe, and usually a mounting hole is left at the head of the substrate for the installation of the brake. The most important four mounting holes on the axle frame are used to install shock absorbers, which are made of materials such as soft rubber or soft resin. Since the inboard and outboard wheels are grounded for most of the time when the skate is skating around a curve, it is necessary to rely on the deformation of the shock absorbers in order to provide centripetal force. Above the shock absorbers are the axle bars on which the wheels are mounted.  The base plate of the axle carrier is very wide and has multiple mounting holes for the upper shoe, which is why the upper shoe does not require much strength. The brakes on speed skates are usually very small.

Shock absorbing pads are usually soft so that they provide a large amount of tilt in order to generate enough centripetal force.  The distance between the two shafts is usually large to provide stable support. The base plate is usually aluminum, after 1990 more and more products use ABS plastic, special nylon manufacturing base plate, this kind of base plate polarization, some low-grade use of ordinary base plate accuracy is poor, poor strength, but cheap, high-quality plastic base plate has enough strength and weight than the aluminum base plate is slightly lighter.

Wheels

Single-row wheels standard width is 25 mm and the wheel along the extreme tip, skidding with the ground contact surface is positively small, so the side resistance is small frontal resistance is also small.  The principle of double row is to rely on the larger diameter of the wheel to determine the speed, the larger the width of the decision of the stronger grip, the greater the hardness of the decision of the lower resistance, the tripod is used to dampen the vibration in the tilt steering.  The single row principle is that the larger the diameter of the wheel determines the speed, the smaller the width determines the resistance, and the stiffness of the wheel determines the damping effect.  Since races are usually held on very smooth surfaces, the durometer of double row wheels is very high, usually between 93A and 97A, which is much higher than the common density of single row wheels, which is between 80A and 90A. The harder the wheel, the less elastic it is and the less resistance it has. 97A wheels are usually used, but if the ground is very slippery, a softer wheel such as 93A is used to improve grip.

The standard width of the outer edge of an indoor double wheel is 40 millimeters, which is also the widest among indoor double shoes. The wider the width, the better the grip so that you can get a good stirring effect when stirring the ice and doing curves. The wider the wheel, the higher the frontal resistance, but due to the high hardness of the wheel and the smooth ground, the frontal resistance is still acceptable. Such a wide cross section is a balance between the skating effect and the frontal resistance, the width of 40 millimeters is the value of experience accumulated over the years.  The difference between double skates and single skates is very big, the main parameters are diameter, hardness, width, weight and material. In the double row of shoes is relatively large, the larger the diameter of the wheel, the faster the speed, but the weight is also large. A common wheel diameter is 62 millimeters, and occasionally you can see a wheel of 66 millimeters. Such a wheel diameter compared with the single row of 90 to 110 mm wheel diameter is not comparable to the wheel diameter of the speed skate wheel.

Wheels and cross-section

Because of the large diameter and width of the speed wheel is very large, so reduce the weight of the priority, so manufacturers in the hub and cross-section up and down a lot of work. Most of the wheels use high-quality plastic to make hubs, high-grade wheels use aluminum alloy to make hubs, hubs are usually very large and hollow, in the installation of bearings in the center of the position of the width is very small, and then with the increasing diameter of the width gradually increase and eventually intersect with the edge of the wheel. Material2

0th century wheels are made of polymer resin, and some types of wheels have a narrow groove in the center to increase grip.

Outdoor doublet wheels can be up to 48 millimeters wide at the outer edge, the widest of all doublets, mainly to improve grip and adapt to rough terrain. The common wheel diameter is 70mm and the hardness is between 80A and 90A. Since outdoor surfaces are usually not very smooth, a larger wheel diameter is necessary to ensure speed and resistance to small particles. Lower durometer means better shock absorption and grip.

Configuring speed skates requires attention to the following points: first of all, it is clear whether the skates are for indoor or outdoor use, and the main difference is in the wheels, which are large in diameter and 80A to 90A hardness, while indoor wheels have a hardness of 93A to 97A and can be slightly smaller in diameter. If both indoor and outdoor speed skating are to be involved in the general selection of outdoor wheels.  The grade of the upper shoes, wheel frame, wheels and bearings should be matched. Wheel frame is very important, if the funds are limited must choose qualified products, it is best to choose high-grade wheel frame.  Double-row speed skating is a common form of competition for the first race, time trial, relay races, etc., and its standard competition venue and single-row speed skating competition is the same that the perimeter of the 200-meter closed site with ramps. Many competitions are often held indoors in gymnasiums without ramps.

The technical action of double-row speed skating is very different from that of single-row skating, and is closer to that of traditional water ice skating. Starting more special, many players will start the leg side of the brake on the ground with two front wheels to form a stable fulcrum, in the start of the use of this fulcrum to pop out the first step, and then in the initial steps of the two legs take turns with the brake on the ground and the two front wheels, and then the upper body is gradually lowered and the use of wheels side of the ground until into a straight line skating. Some competitors even use a crouched start to make the most of the brake start. Upper shoes

The upper part of the skate is the main component that determines the performance of the skate. The upper shoe is generally divided into two parts: the shell and the liner, but the speed skating shoes and individual professional flat flower shoes are not divided into shell and liner. In roller skates, only the speed skates are missing a thing that other varieties of roller skates have, called cuff, which serves to protect the ankle and facilitates the ankle's power to be well exerted. The liner is in the shoes inside the thick layer of sponge things, can be pulled out to wash alone (cleaning before please consult the sales staff, do not privately dismantle and wash), its role is to alleviate the friction between the foot and the shell, the most important thing is that the thick liner cotton can make the skate shoes footwear is very good, so as to put the performance of the roller skates out perfectly, more convenient for the user to learn the roller skating skills.

Knife frame

Knife frame is the metal frame (children's shoes also have plastic) that connects the wheels and the upper shoes. The material and structural form of the blade frame is the second most important point in determining the performance of skates. In addition to some adult professional skates with five wheels, and some very simple children's toy shoes with only three wheels, all other single-row skates are equipped with four wheels.

Wheels

The wheels of today's single-row roller skates are generally PU wheels (only a very few poor-quality skates are plastic wheels), and this material can be adapted to a variety of venues and conditions. The wheels are made up of wheel rubber on the outside and a rigid hub on the inside. The hardness of the wheel rubber ranges from 80A-85A (A is the hardness mark). The higher the number, the greater the hardness and the more wear-resistant the wheel will be.

Bearings

Bearings are mounted inside the hub of the wheel, with one bearing on each side of the wheel and a bearing locating sleeve between the two bearings, which serves to locate the bearings, preventing them from moving in the hub, so as to achieve the ideal state of rotation of the bearings.

Threading nails

The screws that secure the wheel to the knife frame. Usually the holes in the spikes are in the shape of a hexagon, but there are also those in the shape of a plum blossom.

The bottom peg

is the screw that holds the knife holder under the upper shoe. I: Ding standing

Two: eight standing

Three: parallel standing I: T-shaped stop method

Two: two feet to stop sharply

Three: backward sliding stop method ▲Standing posture: a kind of ordinary parallel standing, that is, the two feet are parallel to a little narrower than the shoulder, the knees are slightly bent in order to maintain the center of gravity to the ankle power to control not to let the foot swing from side to side to make sure that the wheels vertical Ground. When you wear professional flat shoes to stand parallel because of the influence of the structural design of the shoes, the two feet will naturally press the outer edge outward. The second one is the T-shape standing (also called T-shape standing) applied to non-flat ground, i.e. the last wheel of one shoe is against the second and third wheels of the other shoe, with knees slightly bent and a slight gap between legs to keep the center of gravity, and still controlling the shoes with the ankles.

▲Start: Start from a T-shaped stance, keep one foot in the forward position, toes forward, the other foot to the side of the body behind the stirrups to push out, there will be the power to move forward. At this time, the center of gravity of the body should be completely placed on the front foot, the body slightly forward (not hunchback), so that the back foot of the force to retrieve the process can be smooth. After the back foot is withdrawn, the other foot will be stomped out to the side and back of the body, and the center of gravity will still be placed on the front foot, and so on.

▲Skating: In order to maintain a good balance while skating, you should bend your knees and waist as much as possible. The purpose is to stabilize the center of gravity and to facilitate power generation.

▲Center of gravity: The center of gravity of the body should always be tilted slightly forward when gliding, and the center of gravity should be constantly shifted with the alternation of the two feet. When one foot is stomping out to the side, the center of gravity of the body must be completely on the other leg, so as to ensure that the stomping out of the leg is very smooth to retrieve. When this leg back to the ground, the center of gravity immediately transferred to this leg, and then the other leg stomped out. Remember to keep your body weight on the other leg every time you stomp. And so on.

▲Skating posture: Bend your knees slightly and lean forward to maintain your center of gravity. The faster you go, the more you bend your knees. The standard skating posture is to have your hands naturally behind your back (without swinging your arms), your back parallel to the ground, and your thighs and calves bent at an angle of no more than 120°.

▲Stop: Skate in the above position, keep your feet close together and parallel, with the foot with the brake block slightly forward, so that the distance between the two feet is about half a foot apart, lift your toes up until the brake block touches the ground, then slowly move your center of gravity to the foot with the brake block and increase the pressure until you stop.
