The Kinematics Analysis To Side Kick Action Of The Second Stage Sanda Athletes

Research purposesSide kick action in sanda attack power is big, the power is strong, it is mainly used for attack to the head,rib and chest, in the fleeting, the athletes of the fast reaction rate and the length of time directly influence the results. This study the reaction ability of secondary athletes, reasonable division side kick action technology action phase, analysis of different stages of the action time, analytical side kick action of hip, knee, ankle joint Angle, the joint point of speed change, and stance, knee, hit the location of the physical characteristics, evaluation of the secondary side players kick action effect, reveal the kinematics characteristics of side kick action, provide theory basis for sanda teaching and training and technical support. Research methods:This article applies the research method of biomechanics, sports college in xi ’an by plane set machine photography side of special secondary six sanda athletes kick action technology of reaction time, reaction ability, time characteristics of different stages of action, as well as the characteristics of the location of the joint Angle, hip knee ankle point of speed change for quantitative analysis. Using height of the center of gravity of the swing ball sandbags unit weight can be more reasonable comprehensive evaluation effect difference, different level athletes for sanda technology and art of teaching, scientific training of actual combat to provide theoretical reference. The results of the study:1.to respond from tests on subjects, 70 Kg, 75 Kg, 80 Kg of reaction time, respectively, 95.8ms,262.5ms and 570.8ms. Athletes from the above data weight big reaction time were greater than the weight small athletes, athletes that big level reflects the speed slower than small levels of the athletes.2.side get kick shangbu stages, knee, blow, blow and recycling five different stages of the movement time were 0.2986 s, 0.1819 s, 0.1322 s, 0.0708 s, 0.9986 s. Embodies the different weight of athletes in different action stages with the player’s own weight, strength, flexibility, coordination has great relationship.3.stance, knee up and hit the sandbags three characteristics of the location of the contact angles of the hip average of 168.41 ° and 136.79 ° and 150.29 °; The knee joint Angle is 168.15 ° and 117.81 ° and 175.99 ° respectively; Ankle joint Angle is 123.53 ° and 136.37 ° and 123.53 °. Due to personal training habits, different posture different so stand up, knees up and contact with sandbags, hip, knee, ankle Angle difference is bigger4. Hip knee ankle toe joint point of speed change are as follows: maximum speed an average of 2.0421 m/s, hip hip hits average speed 1.1089 m/s; Maximum speed of the knee joint with an average of 4.5678 m/s, knee hits average speed of 3.7765 m/s; Maximum ankle speed an average of 7.1378 m/s, ankle hits the average speed of 5.4743 m/s; Toe maximum speed an average of 8.4065 m/s, toe hits average speed of 5.6701 m/s. Immediately before the power stage, hip start first, followed by the knee to start, finally the toe and ankle boot, and in the power and phase to a maximum of its speed5.Sanda athletes hit 5 different weight distance effect obviously, 70 kilograms of two testers struck sandbags height is 51.32 cm and 49.53 cm, 75 kg of two testers struck sandbags height is 56.51 cm and 56.80 cm, 80 kg of two hit by testers sandbags height is 64.67 cm and 64.67 cm. Heavyweight by testers in the hitting effect is obviously better than the lightweight testers. Research conclusions:1. Side in this article, I will kick action is divided into the reaction stage, stage of crust and the knee stage, kick hit six action, combat phase and recovery phase, more accurate evaluation of the side kick technique characteristics.2. From the signal lights to respond to the subjects of weight big athletes reaction time were greater than the weight little athletes, athletes that big level reflects the speed slower than small levels of the athletes.3. Each athlete, is different in different stages of the action time because each athlete’s movement skills, habits, power is different, in the offensive or defensive action move in advance before start small with a small range of movement, movement technology is fast, easy to better offensive or defensive.4. Due to personal training habits is different, standing position is different, so different people, when stand up at the end of the knee, hip, knee, ankle when sandbags and contact Angle difference is bigger.5. Immediately before the power stage, hip start first, followed by the knee to start, finally the toe and ankle boot, and in the power and phase to a maximum of its speed6. Heavyweight sanda athletes hit effect is superior to lightweight sanda athletes, the athletes themselves features are closely related.
