The Influence Of New Material Ball On The Skills And Tactics Of Elite Female Table Tennis Players In China

Table tennis originated in Britain, was introduced into China in the early 20 th century, has been 100 years of history. After European heyday, Japan rise period,China's rise, Eurasian confrontation and the heyday of China so far. The Chinese table tennis team in recent years has won all the champions. Not only because of the coaches and athletes pay hard sweat, is a strong scientific research team in China. On July 1, 2014 the international table tennis federation decided to enable the celluloid new materials made of table tennis. In the new Olympic cycle, the new material ball to our country outstanding female pingpong athletes tactics is very important.In the field of competitive sports, the innovation and reform of equipment has a pivotal role on technique development. After entering the 21 st century rules of all previous table tennis equipment, reform will have some effects on athletes. Table tennis as athletes show their ability and skills of one of the most important media, has experienced from the soft cloth to celluloid ball more than hundred years of history.At present, the material mainly made of celluloid of table tennis, flexible,resistance to water, oil, acid, etc. But at the same time, it is high fever flammable substances,forbidden by many countries in the world as one of the materials used. So using polymer as the raw material of table tennis instead. This new material ball strength decreases, slow, rotation is reduced, so are bound to impact on tactics for the athletes.The rung attacking play football for our country's advantage, made outstanding contribution for Chinese table tennis' s longevity. Chinese table tennis women and cultivate li xiaoxia, ding, liu shiwen, three of the world's top players. Three people in the last Olympic cycle, li xiaoxia 2012 Olympic champion, world champion in 2013,become a grand slam player. Ding won the 2014 World Cup and 2015 world championship. Liu shiwen won the 2013 World Cup champion, second world championships and worldchampionship runners-up in 2015. Three are the competing candidates at the 2016 Olympics in Rio. However, li xiaoxia training less system, the new ball don't adapt to, result in poor condition. Liu shiwen play is characterized byfast speed, but the strength is relatively small, and new material ball velocity slower,larger power requirements of an athlete, liu shiwen could be harmful. Ding leg, but strength is small, the club have effects on the new materials.The purpose of the article is based on ding, li xiaoxia, liu shiwen a celluloid ball and new material in the use of the ball tactics under the condition of the use of statistics and analysis, sums up some problems, regularity of ding and li xiaoxia, liu shiwen adapt to seamless plastic ball, and continue their own brilliant sports to provide scientific theory and reference.Through research we can see that:1) ding use new material ball backwardness did to segment, and the American had fallen to the points won, hair rob and rob paragraphs utilization rate has dropped,the American section of every improved.2) ding using new material ball backwardness rob forehand promised ability improved, backhand promised ability decline. Pick up those who rob segment quality is not high, but the counterattack ability. The American section, ding backhand a lower quality of stalemate, hand position is easy to attack.3) liu shiwen using new material ball backwardness did to segment, and the American had fallen to the points won, hair rob and rob paragraphs of the utilization rate increased, the American usage decreased obviously.4) use new material after liu shiwen, hair grab those ability improved, control ability decreased significantly after service. Those who receive a section of the technical indexes fell. Hand position is in the American section serves to improve slightly, stalemate backhand and sideways rallies are dropped. New material the ball to liu shiwen have effects on the characteristics of fast speed.5) after using new material ball li xiaoxia, hair rob and American serves, meet rob section first. Hair rob and rob paragraphs of the utilization rate increased, the American section of every fall.6) li xiaoxia to use new material after the ball, to those who receive a Duan Youli,to rob and the American has a certain influence. Various technology than using a celluloid ball game errors increase, visible on the ball enough to adapt to new material.Li xiaoxia in those looking for a bad shot points, great influence for the game.7) the use of new materials ball on offensive ability difference, female athletes in training in the future to strengthen physical training, increase the quality, but also because the characteristics of the new material the ball on the tactical change.
