Competitive Changquan Dimculty Movement In Cyclone Landing Foot Balance Stability Study

In this paper, using the method of literature, expert interviews, questionnaire survey method, video analysis, mathematical statistics to participate in Fujian province the fourteenth Universiade D leader fist project race athletes completed the tornado foot landing stability were analyzed, including to the competition in the tornado foot related statistics and analysis, the tornado foot take-off, flight, born three stages of technical analysis and competition analysis, draw the following conclusions:1、The tornado foot in this province the Universiade were men and women generally do, and A-level difficulty; but the tornado foot in Changquan event category generally exist in the ground unstable phenomenon, and the tornado foot360degrees by horse and tornado foot540degrees by horse stumbles up, low completion rates, on the floor after the horse appear mainly foot moves, beating and twisting degree is insufficient.2、The takeoff leg reasonable maximum buffer knee angle, contribute to the lower extremity of the full thrust, improve jumping quality; and limb with rational also can enhance the body’s center of gravity, lift height of jump landing stability, to provide protection.3、Male athlete of the flight time is generally smaller than the female athlete to high, air movements completed more fully; and most female athletes in body curled condition, will gallop ahead into the air to finish, and female athletes in their own strength is poor, in a long device, upper and lower limb coordination uncoordinated, and influences the rotation speed, lead error.4、In the fall when the hip, knee, ankle, through reasonable flexor extensor regulation center of gravity relative to two line support surface position, become the landing stability key. When the rotator shaft and the foot axis projection angle is larger, the focus falls on the supporting surface front, together with the role of inertial body center of gravity continues to fall, athlete to appear before the jump, and vice versa.5、Players in the game will produce some reflect the physiological and behavioral performance, especially excited, rapid heartbeat, blood pressure, and lead to psychological stress, affect the movement stability; in addition affect the competition of the subjective and objective factors on the Changquan item game players to complete the tornado foot landing stability of equilibrium exists generally the influence of subjective factors and objective factors, but is much more important, especially for the game seriously enough, to risk degrees movements do not grasp, lack of competition experience.
