One-foot speed jump pile is a kind of speed obstacle race, and the requirement is one-foot jump pile. For the specific competition mode, I have compiled the rules for the roller skating single-leg speed pile crossing competition for you. Welcome to read.

Rules of single-foot speed jumping competition in roller skating

First, roller skating one-legged racing pile mode

Time trial:

Athletes will perform twice. After the start, there will be an acceleration zone of 12m, and 20 cone piles will be arranged at intervals of 80cm, and the total length will be 12+0.8? 19+0.8 = 28m。 Every time a cone pile is knocked down or a cone pile is missed, it will be punished by 0.2 seconds.

Timing: from the starting line to the finish line. Timing ranking helps to produce KO system.

The rematch (KO system) is divided into the following groups, with two players in each group (taking 32 as an example) = 1 No.-32, 16-17, 9-24, 25-8, 5-28, 21. 11-22, 27-6, 7-26, 23-10,15-18,31-2. (If there are less than 32 employees, Some players don't have to compete with others. The winner goes straight to the next round.

Second, the evaluation criteria

Timing: from the beginning to the end. If a pile is knocked down or missed, the punishment will be extended by 0.2 seconds.

Time test (preliminaries): each person has two chances to compete and record the time.

K O system (rematch): The winner wins in two games.

Third, the competition group

According to KO timing classification standard, the top four players with the best performance (finalists and semi-finalists) are divided into one group; 1/4 finalists are grouped according to the competition results; By analogy, the winners of 1/8 finals and116 finals are grouped.

Fourth, the championship qualification.

Qualifications are ranked based on time. The competition should be divided into at least two groups, men's group and women's group. There can be more or less categories, and then the results of various competitions are summarized or subdivided to produce the winners of ISFA men's and women's groups.

This qualification ranking will not consider those players who have qualified in the qualifiers. In these two groups, 8 men and 4 women will be eligible to participate in the finals of IFSA. In the final, time will be used to decide the outcome. All players will compete in groups according to the KO system.

5.intercontinental cup

The competition should be divided into at least two groups: men's group and women's group. Games can be divided into more or less categories. By adding or subdividing the results of various competitions, we can get the results of ISFA men's and women's groups.

Grouping applies to all players. Champion 20 points, runner-up 19 points, runner-up 18 points, runner-up 17 points, and so on, the 20th runner-up 1 point; The rest do not score.

At the end of the season, all the players' three best results will be ranked in front of the European Cup. In case two players in a certain group are ranked the same, they will be ranked according to the best results of these three games. (according to the timing rules)

Knowledge of roller skates: classification and use of roller skates

First, double-row roller skates

Quad roller skating is a footwork of jumping, spinning and various difficulties in special venues, also known as international figure skating, also known as figure skating. The so-called double-row roller skates, as the name implies, are the most widely used roller skates in major skating rinks, also called patterned shoes. Four wheels are arranged in pairs side by side, with wheels with large outer grounding area and brakes on the front sole.

Second, single-row roller skates

Roller skates are also called inline skates. As the name implies, the wheels on each shoe are arranged in a straight line. According to the function, it is mainly divided into the following categories: casual shoes, speed skating shoes, flat shoes, roller skates and extreme shoes.

1, casual shoes are of course used for leisure, and it is no problem to cope with ordinary street brushes. The wheels are the same size, and the right heel is braked, emphasizing comfort. The shoe shell should not be too soft, otherwise it may cause ankle sprain. The tool rest and vamp of this kind of shoes are generally integrated (except for a few high-end brands), and the wheels are generally made of polyester material to ensure sufficient elasticity and grip effect. The quality of the wheel directly affects the effect and safety of the movement. Children's leisure roller skates are mostly of this kind, and the size of most shoes can be adjusted.

2. Speed skates are also called competition roller skates. In order to reduce the load and give full play to the ankle strength, the upper is relatively short, the height is generally bare or below, and the flexibility is high. The upper is made of full leather, which makes it more wrapped. Speed skating shoes are mainly 4-wheel or 5-wheel shoes, and now there are 3-wheel training shoes as an introduction. The wheel diameter of children is generally 84mm-90mm, and that of adults is generally100 mm-110 mm.. In order to match the big wheels, its tool rest is also longer than ordinary inline wheels. The characteristics of speed skating shoes are that the center of gravity is low to maintain stability when sliding, while the friction on the wheel side of racing car is high to accelerate.

3. Flat shoes are mainly used for freestyle roller skating such as fancy winding piles and fancy brakes, and can also be used for street painting and leisure. Mainly composed of shoes, tool rest and wheels. The vamp is mainly composed of shoe shell, lining and vamp (some parts of carbon fiber shoes are integrated and cannot be disassembled). Shoe shell uppers can be divided into hard and semi-soft ones. Hard upper is wear-resistant, but it has no plasticity, and is more suitable for braking, FSK and leveling. Semi-soft vamp has certain plasticity, and it will fit your feet after long-term wear. Most semi-soft shoes have thermoplastic function (heating the shoe shell with a hot air gun makes the shape of the upper not much different. Some high-grade shoes use triangular support uppers, which improve the flexibility of ankle joints, but the stability is not as good as that of ordinary uppers (generally made of plastic). The triangular support vamp is made of various high-strength fibers. In order to solve the problem of insufficient strength, the existing triangular support vamp is replaced with high-strength plastic. All hard-shell shoes and some semi-soft shoes have detachable linings, while other shoes combine the linings with the shell in order to reduce the weight. The tool rest is detachable and adjustable, made of metal, and has no braking device. The characteristics of flat shoes are mainly reflected in its wheels. The four wheels on a shoe are different in size, and the middle two are slightly larger (generally 4mm larger than the diameter of the front and rear wheels), which makes steering and various fancy movements more flexible.

4. Roller skates are used for roller skating. Because it is an antagonistic event, it requires high strength for shoes. The ball cake used in the game is hard and the ball speed is fast. The toe cap is made of hard engineering plastic, which provides the best protection for toes. In view of the sports mode used in the competition, there is a special design, a towering heel protection system and a long tongue. The upper is half soft, the shoe body is comfortable, and the tool rest leans forward. There are many sudden stops and sharp turns in the competition, so the tool rest and upper shoes are connected by rivets. HI-LO's wheel arrangement is generally small in the first two wheels and large in the last two wheels, which is convenient for sprint acceleration. Adopt multi-shoelace hole design to make shoes fit feet better.

5, extreme shoes, also known as skill roller skates, mostly use lace-up and buckle-type, and it is not easy to be dangerous because the buckle is loose when doing stunts. The base is also lower than leisure roller skates to maintain a lower center of gravity, and the shoe shell is relatively hard, which can provide safety protection and prevent violent impact. Generally, the close distance between the front and rear wheels is to weaken the grip, because too strong grip will make some stunts difficult to complete. The limited bottom plate below the base is used to clamp the steps, and the middle of the tool rest is designed with a clamping groove to facilitate the clamping of the rod.
