| In this paper, high-speed photography with infrared VICON system and KISTLER force plates, and other modern advanced scientific instruments to conduct experimental tests and analysis. From Shanghai sports of University Education Men's Sanshou Team selected 12 athletes, Seven athletes (Athlete) and five general level athletes (level) as the research object, Through the bio-mechanics theory and method of turning back kick Sanda two kinds of technical features and kinetic characteristics of kinematic analysis and comparison, In order to understand the action of two turn back kick technical principles, as well as characteristics and differences, Thus conclude that two kinds of techniques which also help athletes in the race completed and the use of high quality. Therefore, This paper will turn two kinds of movement laws of motion after the kick and technical features to explore and compare them, In order to further improve and enhance the athlete's technical level, For the athletes at the turn after the kick technical movements into consideration during training and application, Sanda coaches for the country's future, turn right after the kick technologies in teaching and scientific training to provide quantitative theoretical basis. Through research found that:1,Two kinds of technical movements turn back kick leg hip angle of attack at the start swivel, raise knee, kick hit three phases do not exist in significant differences. Legs hip rotation at the start swivel stage there is no difference between the two, In one knee raised stage, After the pedal turned legs hip rotation average of 25.02±11.94 degrees, Turn after the kick legs hip rotation average of 35.47±11.69 degrees, There was a significant difference between the two; Kick hit the stage, After the pedal turned legs hip rotation average of 24.01±8.77 degrees, Turn after the kick legs hip rotation an average of 8.29±10.35 degrees, exists between the two highly significant difference. Different levels of athletes turning movements at different stages of post-tread leg hip angle of attack do not exist significant differences.2,Technical movements of two turn attack back kick start swivel legs, knee angle, with one knee raised stage there was no significant difference, respectively. Kick hit the stage, turned legs and knees after the tread angle of attack on an average of 119.58±12.29 degrees, Turned legs and knees after the kick attack on an average angle of 138.99±16.1 degrees, between the two there is a very significant difference. Two kinds of technical movements turned legs back kick knee rotation, respectively in the three different stages were no significant differences. Different levels of athletes turned legs in the attack after the tread moves start swivel angle of the knee, kick hit stage there was no significant difference In stage one knee raised, outstanding group of athletes with average angle of 53.82±8.91 degrees, the general group of athletes with average angle of 68.47±8.25 degrees, there are significant between the two differences. 3,The two turned legs, back kick attacks on technical movements start swivel angle of the ankle, knee raised stage were no significant differences. Kick hit the stage, turned legs and ankle after the tread angle of attack on an average of 102.19±13.91 degrees, turned legs and ankle after the kick angle of attack on an average of 114.97±8.03 degrees, there was a significant difference between the two. After two kinds of turned legs kicking technical movements of ankle joint rotation angle in three different stages were significant differences do not exist. Different levels of athletes turning movements at different stages after the tread ankle angle of attack on legs, do not exist in significant differences.4,The two turned back kick the speed of technological characteristics:After the attack turn tread average time 0.34±0.06 seconds, After the kick attack turn average time 0.44±0.06 seconds; After the attack turn tread average distance of 1.8±0.18 m, After the kick attack turned legs striking distance of an average of 1.96±0.09 m; After the attack pedal turn an average speed of 5.3±1.03 m/s, After the kick attack turn an average speed of 4.52±0.68 m/s; After the attack turned legs tread the reduction rate of an average of 3.86±0.59 m/s, Turn after the attack on the leg kick to restore the speed of an average of 3.35±0.54 m/sec. There were significant differences between both.5,The different levels of athletes turn the speed of movement after the tread technology features:Excellent group attacked an average of 0.3±0.03 seconds, The general group attacked an average of 0.38±0.05 seconds, The t test, P<0.05, significant difference; Outstanding group of striking distance of an average of 1.74±0.24 m, Striking distance of the general group average of 1.86±0.06 m, The t test, P> 0.05, difference was not significant; Excellent group attacked an average speed of 5.94±1.07 m/s, Group's attack on the general rate of an average 4.66±0.47 m/s, The t test, P> 0.05, no significant difference; Good group to restore the speed of an average of 4.32±0.49 m/s, the general group to restore the speed of an average of 3.4±0.15 m/s by t test, P<0.01, there is a very significant difference.6,Turn the power back kick technical movement features:Turn after kicking the greatest force that the average hit is 3601.23 cattle, After the kick turn kick hit the greatest force is the average of 3259.05 cattle; After the turn kicking the average hit time is the greatest force is 1.481 seconds, After the kick turn kick hit the maximum amount of time the average was 1.583 seconds.Two kinds of technical movement turned back kick, After the pedal turned legs combined strength of the average twist is 1050.96±217.45 cattle, Turn after the kick pedal to swivel legs combined strength of the average was 785.68±235.6 cattle, Exists between the two very significant difference. Different levels of athletes, after turning on the pedal movement characteristics in power there is no significant difference.7,After the kick turn the focus of changes in technology, the stage movement characteristics:Start swivel stage,Turn the focus of post-tread average height of 0.98±0.05 m, After the kick turn the focus of an average height of 0.82±0.07 m, There are significant differences; In one knee raised stage, Turn the focus of post-tread average height of 0.96±0.05 m, After the kick turn the focus of an average height of 0.96±0.05 m, No significant difference; Kick hit the stage, Turn the focus of post-tread average height of 1.01±0.05 m, After the kick turn the focus of an average height of 0.94±0.07 m, There are significant differences; Turn after the tread's center of gravity displacement of an average of 0.12±0.07 m, After the kick turn the focus of displacement of an average of 0.06±0.05 m, There are significant differences.
