Research Of The Outstanding Women Table Tennis Players Technical And Tactical Characteristics Of Cotinine In 2012 - 2009

This research of purpose is through on today China woman mainplayers Ding Ning of technical tactical of statistics and analysis, will main playersby using of various technology for quantitative analysis, find different technicaltactical of using number, and category, and effect, for yihou of training andcompetition provides accurate of data support, and to it runs through Yu usually oftechnical tactical training in the, with rich of competition experience forcompetition service.Use literature research method, video observation, statisticalmethods and other methods to urge again and again in28games, a total of140,analysis of data obtained from the General statistics, access to relevant dataanalysis results. The results are as follows:1. Ding Ning in the way between2009-2012and serve a larger change, squat cuthair gradually becomes basic stand-up ball, line flexibility reduces, serving thescoring rate plummeting from the cent in2009per cent in2012, quality is a cleardownward trend, slightly reduced stability. Ding Ning journey appears in the2012London Olympics has been serving fine, to a certain extent, this phenomenon isDing Ning out of2012Olympic champions results because one of the.2.2009-2012Ding Ning in made Rob paragraph, attack technology and controltechnology using rate Basic does not variable, but third plate of attack qualityincreasingly high, to2012attack scored rate reached60.98%, sideways Rob pulledis attack scored of main means, hand pulled of although stability good, but qualitydoes not high, backhand pulled of gains and losses points rate exists larger ups anddowns, overall Shang Ding Ning third plate attack consciousness strong, activeactive, but attack technology Shang pick playing and anti-screwed less, technologyShang slightly explicit single; On the attack and control lines changesconcentrated in the right line and right slash, and more and more right diagonal lineshift to the right, a better effect; fall mainly in the far left and far right, right farhigher stability of the attacking skills of fall, technical fall left far more and higherquality control.3.2009-2012Ding Ning in received Rob paragraph second plate main usingcontrol technology, control technology in the to rub long accounted for main, rublong technology continued progress, but swing short quality does not high, scoredrate from2009of37.04%line declined to2012of17.5%, second plate attacktechnology main using hand pulled and backhand screwed, second is backhandpulled and pick playing, technology using more flexible, fourth plate main using ofis attack technology, second is defense technology, control technology less using, Rob segment and one with a higher stability of the technology, but the quality hasdeclined, not more, attacking skills in backhand more and more usage rose fromper cent in2009to per cent in2012, both high quality are being used less and less,but for best results. Rob line changes, in General, more flexible.4.2009-2012Ding Ning stalemate without using control technologies, mainlyattacking skills, more defensive techniques, stalemate phase plates for a few more,change-over. V plate attack technology using by accounted for share large, usingrate and scored rate line rose,2012respectively reached77.46%and46.38%,quality high, this and third plate of attack and control quality high phase echoed,third plate increases has on opponent technology of control and threat, to v platemanufacturing has more active attack of opportunities, VI plate still to attacktechnology mainly, but defense technology share also increased has, defensetechnology stability high. Attacking skills right linear v works well, but the rightline of Defense technology use is a big problem. Plate VI offensive lines moreflexible. Points on the overall stability is not enough. After seventh and mainattacking skills, offensive line right slashes poor stability and fall right away, losingeasily.5. From this years Ding Ning of major competition in the can seen,"Qian third"convergence more compact, attack consciousness also strong, backhand pulled isDing Ning main using of attack technology, control and defense technology usingmore, makes competition more to entered has more plate number of stalematecompetition stage, attack line, and placement of flexibility enough, like v platedefense technology of right line on exists larger of problem, offensive anddefensive conversion missing active, attack threatening enough, new of serveroutine of formed is win of key.
