Research on the Key Technical Characteristics of the Backward Three-Steps of Outstanding Male Pole Vaulters in China

WANG Guanglei

Physical Science College,Hefei Normal University,Hefei, Anhui Province,23o6O1 China [Abstract] Objective:To analyze the technical characteristics of the backward three-step technique between outstanding male polevaulters in China and those inthe world,itcompares theiradvantagesanddiferences,and provides reference for optimizing training and improving technique.Methods:Using a high-speed camera at 3Oo frames per second, the parameters of Huang Bokai and Zhong Tao,two international athletes,whoatempted multiple jumps were recorded. TheSIMIMotion9.2Oanalysis system was used for digital processing,andthe dataof Huang Bokai and Zhong Tao's multiple jumpsatdiferentheights erecompareddomesticallyandinternationallyResults:Firstly,thetwooutstanding malepolevaulters in China showedsmall,bigandsmall gait withasignificantdiferenceinstridelength wasobvious. The diference ofstep length between backward step2 and backward step 1 was positive,whilethat of world-clas athletes is a negative number.There isasignificant difference in their take-offstyles compared to world-classathletes. Secondly,interms ofthehorizontal speedofthecenterof gravityinthe last three-steps,domesticathletes outperform 基金項(xiàng)目:安徽省高校自然科學(xué)重點(diǎn)研究項(xiàng)目(項(xiàng)目名稱:我國優(yōu)秀撐桿跳高運(yùn)動(dòng)員助跑起跳技術(shù)的運(yùn)動(dòng)學(xué)研 究,項(xiàng)目編號(hào):2024AH051559);安徽省運(yùn)動(dòng)健康信息監(jiān)測技術(shù)工程研究中心開放課題(項(xiàng)目名稱:人體 簡單動(dòng)作運(yùn)動(dòng)學(xué)標(biāo)準(zhǔn)數(shù)字庫構(gòu)建研究,項(xiàng)目編號(hào):KF2023007)。(剩余7805字)
