Experimental Study On Response Ability And The Effects Of Sanda Athletes Action About Level 2 Of Different Heavyweight

Research objective:Competitive sanda competition, fast changing, fast attack and defense conversion speed, technical and tactical changes, the reaction ability of athletes, the speed of reaction and the length of the reaction time directly affect the outcome of the game. Especially for the high resistance, high intensity of Sanda Sports, the reaction time and combat effectiveness as a measure of the athletes’action technical characteristics and action to reflect the Sanda project "fast, accurate, ruthless" characteristics. Through the experimental test and analysis, reveal the characteristics of the reaction ability and the striking effect of different weight level athletes, and provide the theoretical basis and technical support for the teaching and training of Sanda.Research method:The plane machine photography Xi’an Institute of physical education 12 Sanda secondary athletes straight punch, is kick and whip leg movements of the continuous motion picture by Shanghai Institute of human motion image analysis system and analysis of Sanda Athletes of different movements, obtaining the response of the different weight level Sanda athletes, action, reaction speed index and different action combat effectiveness. Evaluation of different levels of Sanda Athletes in the same action and the same level of different movements of the reaction ability, reaction speed and the effect of the difference.The results of the study:1. Lightweight athletes straight punch, is kick reaction time were faster to heavyweight differences significantly and (P<0.05). Whip leg (P<0.01), the difference was very significant.2. The lightweight and heavyweight action of different action average respectively after straight punch is 0.100 s,0.150s; kick for 0.115s,0.168s; whip leg 0.137s 0.275s; two different levels of athletes straight punch, is kick compared (P< 0.05) differences significantly, the whip leg (P<0.01) difference is very significant.3. Lightweight Sanda athletes straight punch, is kicking and whip leg reaction speed respectively 1.369s/m,1.345s/m,1.413s/m; heavyweight after straight punch, is kicking and whip leg reaction speed 1.229s/m,1.296s/m,1.334s/m.4. Lightweight Sanda Athletes in FLAC straight punch, kick, whip leg finished recovery action back in time are 0.412s,0.618s,0.737s and heavyweight three action after the completion of the recovered from the time 0.407s,0.629s,0.742s, with a different level of significant difference (P<0.01).5. Different heavyweight Sanda athletes three action to combat the effect has obvious difference, lightweight Sanda athletes and heavyweight Sanda athletes flip straight boxing sandbags swing height were 0.378m 0.397m, whip leg sandbags swing height were 0.465m 0.468m, is leg hitting sandbags swing height respectively for 0.468m 0.472m same heavyweight action of different sandbags swing height difference remarkable, is clearResearch conclusion:1. In the same action is completed from the signal lamp light to subjects who have action big players reaction time performance was higher than that of small weight athletes that small level athletes response time than the high level athletes to short quick response. The same level of athletes to complete different actions, the upper limb movements of the reaction time for short lower limb action reaction time.2. Sanda athletes completed the same action, regardless of the completion of upper extremity basic movements or limb movements lightweight athletes action time action time short, fast action, heavyweight action for a long, slow. At the same level, the action time of the upper limb is shorter and the action time is longer, and the difference is significant.3 whether it is from the reaction ability data analysis, or from the reaction speed, the light weight Sanda athletes reaction ability and reaction speed is significantly better than the heavyweight Sanda athletes.4 in addition to direct fist, kick, lightweight athletes are slightly shorter than the whip leg heavyweight, but the difference was not significant. Note that different levels of athletes at the end of the impact of the action and the recovery of their weight, strength and not much relationship, and the athletes themselves and the action of the technology, habits.5 different heavyweight Sanda athletes to complete the same action to combat the effect of little difference, the same level of players to complete the different action to combat the effect of a large difference.
