Abstract

In this paper, experimental testing and analysis with the VICON infrared high-speed photography and KISTLER dynamometer Taiwan, and other modern advanced scientific instruments. Selection of 22 athletes, six elite athletes (elite level) and six general-level athletes (one less) as the object of study, through biomechanical principles and methods of transit Sanda behind kick from the Shanghai Institute of Physical Education Men's Sanshou team Kinematic Characteristics and analysis of dynamic characteristics and comparison, kicking movements turned to understand the technical principles and characteristics, which summed up the two technologies which contribute to the completion and use of high-quality players in the competition more. Therefore, this article will be turned back kick law of motion and technical characteristics to explore and compare them, in order to further improve and enhance the technical level of athletes kick in after the turn for athletes the technical action training process to reference and application of Sanda coaches turned back kick technology teaching and scientific training in the future to provide a quantitative theoretical basis. The study found: both turned twist start kicking the technical action attack legs hip angle, knee, kick strike three stages do not exist significant differences. Hip angle of rotation of the supporting leg at startup twist between the two there is no difference in the knee raised stage, after kicking supporting leg hip rotation angle turned an average of 25.02 ± 11.94 degrees, turned after the kick the supporting leg hip rotation angle average 35.47 ± 11.69 degrees, both the existence of significant differences; kick hit the stage, turned hip angle of rotation of the supporting leg after kicking an average of 24.01 ± 8.77 degrees, turned to kick the supporting leg hip rotation angle averaged 8.29 ± 10.35 degrees, two between the existence of a very significant difference. Different levels of athletes turned hip joint angle of attack at different stages legs kicking action do not exist significant differences. 2, both turned around after kicking action attacks leg knee angle at startup twist, knee raised stage were no significant differences. The kick hit the stage, turned leg knee angle after kicking attack an average of 119.58 ± 12.29 degrees, knee kick attack after legs turned an average angle of 138.99 ± 16.1 degrees, very significant difference between the two. Both turned around after kicking action supporting leg respectively were no significant differences in three different stages of the angle of rotation of the knee. Kicking the action attack leg knee angle different levels of athletes turned on startup twist kick hit the stage were no significant differences in knee raised stage, outstanding group of athletes average angle of 53.82 ± 8.91 degrees, the average angle of the general group of athletes 68.47 ± 8.25 degrees, a significant difference exists between the two. Both turned ankle angle kick action attack legs swivel at the start, one knee raised stage, respectively, are not significant differences. The kick hit the stage, the kicking attack leg ankle angle turned around after an average of 102.19 ± 13.91 degrees, turned kick attack leg ankle angle after an average of 114.97 ± 8.03 degrees, both the existence of significant differences. The ankle of the supporting leg kick technique action both after the turn angle of rotation in three different stages do not exist significant differences. Pedal action after different levels of athletes turned ankle angle of attack at different stages legs do not exist significant differences. 4 speed characteristics of the two turned back kick: turn around after kicking the attack time is an average of 0.34 ± 0.06 seconds, the time of the attack after the kick turned an average of 0.44 ± 0.06 seconds; striking distance after kicking turned an average of 1.8 ± 0.18 m kick attack, turned legs striking distance of an average of 1.96 ± 0.09 m; turned after kicking the attack speed of an average of 5.3 ± 1.03 m / s, the attack speed kick in after the turn of an average of 4.52 ± 0.68 m / sec; turned after kicking attack The legs of the average reduction rate of 3.86 ± 0.59 m / s, the reduction rate of the leg kick attack turned around after an average of 3.35 ± 0.54 m / sec. Respectively, there are significant differences. 5, the different levels of athletes turned pedal technology action of speed characteristics: outstanding group of attack time average of 0.3 ± 0.03 seconds, the general group attack time average to 0.38 ± 0.05 seconds, there are significant differences; outstanding group of attack distance average for the 1.74 ± 0.24 m, the general group of attack distance average to 1.86 ± 0.06 meters, the difference is not significant with sex; outstanding group of attack speed average to 5.94 ± 1.07 m / s, the general group's attack speed average to 4.66 ± 0.47 meters / sec. significant differences in vain; outstanding group average reduction rate of 4.32 ± 0.49 m / s, the average reduction rate of the general group was 3.4 ± 0.15 m / s, there are significant differences. 6, turned Kicking action force characteristics: Turn kicking hit the maximum power of the average is 3601.23 cattle, turned kick kick hit the average of the maximum power is 3259.05 cattle; turned around and kicking strike the average time of maximum force is 1.481 seconds, turned around after kick kick hit the maximum amount of time the average is 1.583 seconds. Both turned around after kicking the technical movements, after the turn the pedal support legs twist together the power of the average is 1050.96 ± 217.45 cattle, turned to kick the supporting leg swivel stomp aggregate power of the average is 785.68 ± 235.6 cattle between with a very significant difference. Different levels of athletes turned pedal action strength characteristics, there is no significant difference. 7, turned back kick phase variation of the center of gravity of the technical movements; start twist, the average height of the center of gravity kicking in after the turn of 0.98 ± 0.05 m, the average height of the center of gravity kick in after the turn of 0.82 ± 0.07 m, there is significant difference ; kicking knee raised stage, turned after kicking the center of gravity of an average height of 0.96 ± 0.05 m, and the average height of the center of gravity kick in after the turn of 0.96 ± O.05 m, the difference was not significant; kick hit the stage, turned the average height of the center of gravity 0.06 ± 1.01 ± O.05 m, the average height of the center of gravity kick in after the turn of 0.94 ± 0.07 m, there are significant differences; displacement of the center of gravity kicking in after the turn of an average of 0.12 ± 0.07 m average displacement of the center of gravity kick in after the turn 0.05 m, there is a significant difference.
