Analysis Of The National Youth Team Players In Xi’an Physical University Race Walking Part Technical Comparison

Race walking, as the special project of the track and field sports,is the only oneproject by the referee subjective judgments. Walking technology is the priorityamong priorities, the game referee subjective judgment makes greatly influence onplayers ’performance.Once the player was judged to be foul, it will lead to seriousconsequences directly disqualified, all the hard training will be cast to waste.walking rules changes guide the development direction of athletes technology. So wemust grasp the essence character of walking, try to figure out the change, and put itinto practice, which can withstand test in practice, only in this way, the developmentof China’s walking cause positive and healthy can be guaranteed. The following is theresults in this study:1.The measured15-16years old young stride length and stride frequency: women1.05M and3.26steps per second, compared with the national outstanding players,frequency less0.19steps/s, nearly equal step length, so that the young woman needto increase the frequency; men1.09m and3.10steps per second, compared with theexcellent male athletes step length, stride frequency are less0.04, the same youngman should also key improve in the frequency aspect. women24.67ms and men25.17ms flight time is within the normal range, comply with the new rules.2. The measured vertical center of gravity displacement of15-16year-old walkers:Women1.03cm, longer than the national outstanding players0.19cm, young femaleathletes great center of gravity vertical displacement is not conducive to horizontalvelocity; men is0.92cm, less than the outstanding members of the countries0.03cm,slightly smaller than the excellent athletes, in favor of the horizontal velocity; theknee joint angle: women176.24degrees at the moment reaching the field,150.27degrees at the moment from the field, compared with elite athletes, the momentreaching field knee angle smaller0.96°, the moment from the field the knee angle islarger1.52°. Men the moment of reaching the field176.89°,the moment from thefield146°, by contrast, the moment of reaching ground knee angle larger3.43°, theangle smaller4.25°from the field. Supporting leg ankle joint angle: women reachingground112.92°,112.29°vertically, from the ground134.30degrees, compared withelite athletes, reaching ground angle of ankle smaller1.18°,smaller3.32°vertical,the ankle joint angle larger1.65°, men reaching ground109.28°,111.15°vertically,reaching ground133.63°, under, with ankle angle smaller6.28°, vertical ankle anglesmaller5.87°, from the ground the ankle angle larger2.15°; while in the elbow angle,difference between players is very obvious without comparable. 3. The measured the average speed of15-16year-old walking race athletes: Women3.51m/s, by contrast, little0.32m/s; men3.94m/s, by contrast, less0.29m/s, it can beknow that there are still ascension space for young Players’ speed.
