Research On Subsection Speed Characteristic Of Speed Skating500m Ladies Athletes In China

Speed skating is the distance to the provisions for the purpose of racing skating competition, or that is as a racing sports equipment skate on ice, and it is one of the ice sport. Chinese women’s500m short distance speed skating has always been the most likely impact of the project impact the Winter Olympics gold medalTo ensure the continuation of the traditional advantages of the project, to further improve the level of the athletes, the speed of response to women’s500m project features segmented China has a more comprehensive and in-depth understanding. In this paper, the results of the League staging point speed data support, analyzed and discussed the Sectional, while referring to a large number of documents and conducted several interviews with Chinese women speed skaters league results are sorted integration measure athletes age, condition, disease, training level, and then the best results, a reference site records, in accordance with the final score of this game to reorder, remove uncertainties appear in the game, effective control of observational data for further screening, the final deliberations of the athletes to communicate with experts divided elite athletes (elite), elite athletes (well trained level), ordinary players (normal). The three groups of athletes in accordance with the starting phases, the first phase of corners straights stage, the second stage of the curve, the final stage which five different stages itemized comparative analysis, the following conclusions:(1)No significant difference in the starting phase of a three athletes. Three groups of athletes at the starting stage of rapid acceleration from zero speed to a suitable speed into the corners, as the distance increases, the speed gradually expanded points of difference, but the curves are basically the same direction, there is no significant difference.(2) Into the first corner stage, the top1/3of the slow curve acceleration phase, after point8was quickly pulled after speed acceleration curve slope which is significantly higher than other elite athletes two athletes, and elite athletes acceleration curve slope above the ordinary athletes, three groups of athletes speed consistent trend. The first three corners accelerated expansion of the difference in athletic performance(3) Straight stage athletes try to keep out of the first corner corner speed, lane change after a more appropriate speed into the second corner.(4)After entering the second curve, velocity curve obviously three groups of athletes, elite athletes reach the maximum speed at this stage, indicating a reasonable use of the acceleration curve to create the conditions for a high speed corners. When elite athletes speed into the corners in the second phase of the curve decreased significantly after point14no apparent acceleration characteristics. Do not use ordinary athlete accelerated this characteristic curve(5)The final stage of elite athletes and elite athletes try to maintain a steady speed taxiing speed undulating curve, steady decline. Ordinary athlete second curve acceleration is not obvious, in the last stage of accelerating large fluctuations...
