Experimental Study Of Core Training’s Influence To Static Balance Of Women’ Moguls Freestyle Ski Of National Team

With the update and development of training concept，core training is gradually accepted bymost high-level sport teams. However, there are few reports about the influence of core trainingon high level athlete’s static balance till now. This research aims at finding out the relationshipbetween core training and high level athlete’s static balance ability of Free style ski of Moguland analyzing core training’s role in Free Style ski of Mogul Physical training system in order toprovide functional evaluations and sport selection references for athletes.This article is written on the basis of a research in which three female national teamathletes who take part in core trainning for16weeks--two core training classes per week. Threestatic balance tests are made before the test starts, after the8weeks’ training ends and the16weeks’ training ends. Test datas are compared and analyzed from the perspective of the X axismoving distance, the average velocity of X axis, the Y axis moving distance, the average velocityof Y axis.Results of the research: taking athlete NingXX’s speed-torque as an example, because speed-torque t can directly reflects the overall balance ability of athlete. That index is called aslow index.1Before the training, stood with left leg and with eyes opened, speed-torque is53.8mm2/safter8weeks training, speed-torque is57.2mm2/s, after16weeks training, speed-torque is37.2mm2/s.2Before the training, stood with right leg and with eyes opened, speed-torque is54.6mm2/s,after8weeks training, speed-torque is44.8mm2/s, after16weeks training, speed-torque is29.9mm2/s.3Before training, stood with left leg and with eyes closed, speed-torque is216.4mm2/s after8weeks training, speed–torque is117.7mm2/s. After16weeks training, speed–torque is21.3mm2/s.4Before training, stood with right leg and with eyes closed, speed-torque is160.6mm2/s after8weeks training, speed–torque is114.2mm2/s. After16weeks training, speed–torque is115.2mm2/s.5Before training, stood with legs and eyes opened, speed-torque is5.9mm2/s after8weekstraining, speed–torque is31.8mm2/s. After16weeks training, speed–torque is6.4mm2/s.6Before training, stood with legs and eyes closed, speed-torque is15.1mm2/s after8weeks training, speed–torque is21.4mm2/s. After16weeks training, speed–torque is9.8mm2/s.Conclusion of the research:1.core training has an obvious influence on the balance ability tostand with one leg and with eyes opened.2. Core training’s influence on balance ability to standwith oneleg and with eyes closed has improved in the fisrt8weeks’training, but no more obviousimprovement is showed after the whole16weeks’ training.3. Core training has no obviousinfluence on balance ability to stand with legs.
