(I) development of unicycle abroadThe wheelbarrow movement combines the requirements of acrobatics, physical agility and balance ability.In Japan, for example, in 1978 set up the study of relationship between unicycle movement and human health of body and mind, to promote unicycle movement, to training of instructors, unicycle association held a national games.Lottery association in 1981, in Japan and the Japanese ministry of culture, under the support and guidance of unicycle associations across the country set up a "designated to promote the school sports" promote the development of the unicycle sports sports to promote the school is equipped with 2000 a year for fixed-point unicycle.After years of development, 95% of primary schools in Japan carried out unicycle sports and equipped with specialized sports equipment.In 2011, the survey data of the Japan unicycle association indicated that the association had developed 84 branches nationwide and more than 5 million members.Unicycle movement development cannot leave the cultivation of the instructor, Japan unicycle association in 1989 won the Coca-Cola company with the support of the Japanese bicycle association, held every year in Japan 25 region unicycle sports instructor training course, receive special training, Japan's nearly seven thousand people had the unicycle sports instructor ability and aptitude.Japan unicycle movement of game and two kinds of exhibitions, depending on the match according to the distance divided into two kinds of events, 100 m and 400 m, according to the difficulty into one foot ride game, barriers to competition, marathon.In Japan, the record for the 100-meter race is a record of 1 hour and 56 minutes for the 12-second, 642 km marathon, which is set to refresh every year.Exhibitions including personal exhibitions, double exhibition, group exhibition projects, such as different actions under the music melody accompanied by performance, the judges according to the player's movement difficulty, degree of performance, complete degree scores.From the point of view of the performance, the exhibition game of the unicycle can be played on the shoulders and in figure skating and swimming.In 2011, the Japanese unicycle the attendance of the conference 1500, distributed in more than 40 domestic branch were held in the conference, unicycle movement in Japan has become a popular fitness programs.(2) development of domestic unicycleUnicycle movement in China started late, but development speed quickly, a few years was approved by the state general administration of sports, become our country of the planned project sports competition, and become the community recognition performances, often appear in large celebrations performances.In recent years, in order to promote the popularity of unicycle sports in our country, the state general administration of sports in an active part in the world unicycle championships at the same time, held once every year in the domestic national unicycle championships, launched in 2003 and the highest level of competition in the field of national unicycle "" classic", the event launch marks the birth of the unicycle grand prix in China, the historic breakthrough significance.At present, the compulsory education school in some provinces and cities has begun to promote the unicycle movement.Compared with traditional sports, the unicycle sport has both the characteristics of performance and competition, and also emphasizes the important role of cooperation, communication and coordination.By taking part in the unicycle competition, teenagers can both exercise their comprehensive qualities, feel the pressure of competition and the joy of success, and enrich their own leisure life.The quality of our country education reform to cultivate teenagers all-round development, unicycle movement characteristics consistent with requirements of quality education of our country teenagers, is a healthy positive sports entertainment.Second, the unicycle sports feature perspective(1) light extreme challengeThe unicycle movement combines the characteristics of surprise, qi and danger, which can be very challenging.China's unicycle technology is divided into ten levels from low to high.First-class technical level can get, in situ independent please write without other auxiliary material, independent distance above 50 meters, can be fixed by in situ machine-cleaned pulled into a car, can be realized in the process of riding forward or backward, the car can turn in the course of cycling flexible.With the improvement of technology level, the cycling difficulty of the wheelbarrow is increasing.Tenth level technical level to the highest level of the unicycle movement technology, need to master more than 12 types of car, can be in the rear ride and one foot down on the formation of "eight" word, can go round and round in a single foot fall ride form under the condition of the circle, freewheeling, side a, single foot wheel fall a distance up to 10 meters, won the world championship or national championship number three.(ii) balance coordinationThe wheelbarrow movement has made certain demands on the balance coordination of operators.If the front to look at the unicycle, will consider shaking rollover risk, because of the unicycle wheels in the central, will produce similar to pour lever, require the operator to maintain unicycle about balance itself.When the wheelbarrow begins to move, the load of the whole load is carried by the wheel to maintain the power of the wheelbarrow, and the strength of the force is the product of its mass and acceleration.When the wheelbarrow begins to climb the slope, the original balance will be broken and the operator needs to establish a new balance through the adjustment of its own strength.In ascent, the operator should exert upward force to counteract the friction of the ground and maintain the balance of the unicycle.On the downhill, the opposite is true.When the unicycle is not perfectly perpendicular to the ground, it requires the operator to exert the opposite force on the handle to counteract the force of the cartwheel.(3) competitive sportsThe sport of unicycle is very interesting.The skills of the unicycle are so varied that there are more than 12 ways to get on the bus, such as stepping on the bus, kicking the car, jumping on the car, etc.There are many variations in the cycling process, such as: 90-degree and 180-degree, one-foot cycling, jumping, gyro, etc.It can be combined with other sports to form new projects, which cater to the curiosity of teenagers and the psychological characteristics of conquest, which have a strong interest.(4) carrying convenient, economical and limited activitiesUnicycle volume is small, can be in the car trunk, can also be brought to the office, very convenient to carry and unicycle price from a few hundred yuan to one thousand yuan, beginners can choose a few economical unicycle movement brand, service life can reach more than 20 years, both for individuals and families in general can afford, only the equivalent of a mid-range toy price level.The unicycle movement can be practiced even within 5 square meters of indoor, the road, the forest lane, the courtyard can be used, the activity restriction is little, easy to carry out.
