| Since 1996, WuShu Competition Rules specifying the difficulty to start movements to movements of WuShu competition level of difficulty and quality greatly improved. Competitive Rules in subsequent years changed several times, still inherited and developed this initiative. 2003 Competitive Rules in a more explicit specification of the difficulty level of difficulty of movements made clear specifications and marking requirements, to the objectivity of martial arts competition score significantly improved, but also to promote WuShu has entered a new stage of develop. In addition, the difficulty of the content of action rules in detail in the provisions, a total of three movements, namely balancing class, leg type and jumping classes. One of its jump Maneuver "high", "difficult", "beauty" of operating characteristics is widely used in the routine schedule in.In this study, the use of literature, experimental and mathematical statistics of Competitive Athletes jump B-grade side Somersault Maneuver 360°were studied. The whole action process is divided into three stages --- Jumping Run-up, vacant twist stage, landing phase study, the following conclusions: the end of athletes in the run-up moment, man landing angle is 55.98±1.85°, Women's landing angle 52.85±6.55°. According to the completion of tested athletes know that the angle of the value of land help to complete the action; in action Jumping buffer stage, the maximum buffer time Knee angle: Men 138.11±19.60°, for women 146.69±1.39°, this angle suitable for Jumping legs kicking hard. In the Jumping phase, carried out with the buffer action, swing leg (right leg) with the left hip flexion acceleration on the swing, his arms by the elbow before the hem folder to mention shoulder suddenly get a downward force on the inertia ground, the ground reaction force to pass Jumping legs, increased Jumping legs push off the ground forces to gain a better jump height. Jumping athletes in lower center of gravity horizontal speed, vertical speed increased, maximum vertical velocity: Male athletes 4.09±0.60m / s, female athletes was 4.27±0.50m / s, maximum take-off leg in vacant moments. Flight phase, moment to vacate vacated the highest point, the focus of a high degree of male athletes of the relative value of incremental 27.48±4.99%, female athletes focus on the relative value of 23.55±incremental 2.90%. Flight phase, players turn over the body vacated vertical moments for all tested athletes in the air have knees, hip flexor, sub leg action, especially when vacant land is far less than the body and the vertical angle of the clip legs about men athletes angle of 29.93±14.48°, the angle between the legs of female athletes is about 4.96±3.91°, male torso with an inclination of 54.09 persons athletes 10.93°, female athletes trunk inclination of 49.65±1.89°. Flight phase, contestants had vacated inverted vertical, the left and right leg through the hip flexor postural adjustments such as increased speed of body roll; landing stage degrees swivel female athletes as less than the air, the body still in the ground turn time , an increase of the load floor when the lower limbs, so time-consuming process of female athletes landing stability than men, female 0.32±0.02s, male 0.29±0.04s, because jumping height and landing flight time limitations lead to poor stability. The total time-consuming between Male and female athletes to complete movements is not very different, male 0.64±0.02s, female 0.63±0.03s. Male Athletes of the flight time is slightly larger than female athletes, male 0.24±0.01s, female 0.23±0.01s, conducive to the completion of the air rotating movements. |
