| ObjectiveBoxing punching technology is a general compound poly-joint movement all over the body.Basd on analyzing the special strength characteristics of the lower limb in different punchtechnology, this study focus on discussing the effects of lower limb fast drive force on the punchresult and punch speed.Our study is to improve the equipment of the lower limbs and trunk special strength trainingand monitoring system software, in order to prvide services for practice training.On the theoretical basis of boxing lower limb special fast strength characteristics, we use themaximum power method during the trainsition period of special strength traning. Using strengthtraining and combining conventional training, we use the boxing special strength training andmonitoring system for8weeks, the process compare with conventional strength training controlgroup. The experiments are verified the practical stability and safety and texted the effect ofspecial strength training methods.Methods and Objects:16elite male boxing athletes are tested and researched. Research methods includedocumentary research method, survey method, experimental method, mathematical statisticsmethod, exploratory study method, et al.Experimental Methods:Using two pieces of3D measuring force platforms (Kistler, Switzerland) and high-speedinfrared imagine system(Vicon, UK) synchronously, we keep the kung fu test engineering artificialas fixed hit goal, and collect the kinematics data of punch velocity and punch results of the fastdrive force of jab, back straight punch and back hook limb. At the last, we observe the differentpunch technologies of lower limb special strength characters and the effects of lower limb fastdrive force on the punch result and punch speed.Exploratory study method:The study invent boxing auxiliary strength training equipment and software of the monitoringsystem that application to boxing special strength training, and implement the real-time dataacquisition combining the training parameters later processed effective combination.Empirical method:At the trasition phase, the experimental group undertake strength training for8weeks, andthe control group undertake general strength training content, the practice of the control group isconventional strength training, the experimental group use boxing special strength training system,additional special strength training content except the same content of control group. Comparewith the changing of the Jab lower lamb speed strength parameters between the experimentalgroup and the control group before and after the experiment. power number changes, and thesuccessful keep boxing feet turn power training before and after the experiment,and the changingof Pedal to turn power of back straight, training punch velocity and punch result. Our aim is toverify the practicability safety a of the invented equipment and special strength training result andto drive force are very important to improve the result of jab punch, Improving the double feetmaximum force and the speed of drive force are very important to improve the result of backstraight punch in active push-off phase. Results:1Jab punching, In the active push-off phase, the forefoot achieve peak force in0.084±0.018s, andthe time of backfoot is0.057±0.013s, the force can reach more higher percentage of maximumforce in50ms.2Back straight punching, In the active push-off phase, the forefoot achieve peak force in0.197±0.044s s, and the time of backfoot is0.133±0.031s，the force can not reach more higherpercentage of maximum force in50ms.3There are highest linear fitting degree between forefoot maximum strength/weight, speedstrength index/weight and punch speed punch result, showed a linear positive correlation (P<0.01);and there is highest curve fitting degree between the time reach maximum force peak and punchspeed punch result, showed a curvilinear relationship(P<0.01) And the other three backhandboxing technology double feet show the same feet above rapid hair force parameters and throw apunch velocity related and curve fitting method, regression analysis results and the former handkeep boxing forefoot results are close to each other.4The boxing special strength training and monitoring systems through the relevant authoritiesappraisal, has obtained the national patent for utility model and software copyright.5After8weeks training, the fast strength parameters of the experimental group Jab forefoot showa significant growth (P <0.05), the control group show the growth not significant (P>0.05), theincrease rate of the experimental group was higher than the control group (P <0.05). The punchspeed and punch resultf of the experimental group a significant growth (P <0.05), the controlgroup show the growth not significant (P>0.05), the increase rate of the experimental group washigher than the control group (P <0.05).The kicking transfer power of the experimental groupshow a significant growth (P <0.05), the control group show the growth not significant (P>0.05),the increase rate of the experimental group was higher than the control group (P <0.05). Theappropriate workload of the double groups show the growth not significant.(P <0.05), there is nosignificant difference between the two groups after the experiment (P <0.05). The punch speedand punch resultf of the experimental group a significant growth (P <0.05), the control group showthe growth not significant (P>0.05), the increase rate of the experimental group was higher thanthe control group (P <0.05).Conclusion:1The Boxing different technologies special strength characteristic and punches hit the lowerextremities, Jab punching double leg special strength consistent with starting power characteristics.Back straight punching double leg special strength consistent with starting power characteristics.2Improving the fore leg maximum force and the speed of drive force are very important toimprove the result of jab punch, Improving the double feet maximum force and the speed ofdrive force are very important to improve the result of back straight punch in active push-offphase.3As a whole body multi-joint project, The effect of lower lamb fast drive force on punch speed inboxing punch has the same law as same limb fast drive force effect it’s own movement speed.4The boxing special strength training and monitoring systems can meet the training requirements,it has High practical value, and can be promote to using.5Combined Maximum power, start strength training with conventional strength training, useingboxing special forces training system at transformation period, Special forces training systematic,can development of athletes lower limb special forces effective, thus contributing to the punchingspeed and the punch result growth effective. The training method has certain advantages toconventional strength training for improving special speed force,... |
