優(yōu)秀競(jìng)技健美操運(yùn)動(dòng)員C477和C479難度動(dòng)作運(yùn)動(dòng)學(xué)分析.pdf

1、摘要競(jìng)技健美操難度動(dòng)作在競(jìng)技健美操中起著骨骼支撐的重要作用，是衡量運(yùn)動(dòng)員技術(shù)水平的重要標(biāo)準(zhǔn)，它不僅決定難度分，還從編排、完成質(zhì)量等方面影響著藝術(shù)分和完成分，是比賽取得勝利的關(guān)鍵因素。競(jìng)技健美操四類難度動(dòng)作中對(duì)C組難度動(dòng)作的研究數(shù)量最多、難度最廣、類型最豐富，C組難度動(dòng)作與最終成績(jī)直接相關(guān)。然而，我國(guó)對(duì)競(jìng)技健美操的研究目前都只是針對(duì)中度偏難的動(dòng)作進(jìn)行運(yùn)動(dòng)學(xué)分析，對(duì)高難動(dòng)作進(jìn)行運(yùn)動(dòng)學(xué)分析的研究相對(duì)較少。本研究運(yùn)用三維實(shí)驗(yàn)測(cè)量法、專家訪談法、

2、對(duì)比分析等方法，對(duì)江西師范大學(xué)健美操隊(duì)隊(duì)員壽曼超、潘芑驥、王孝煒、席岳峰、鄭然驊和曾聰六名優(yōu)秀男子競(jìng)技健美操運(yùn)動(dòng)員完成C477“轉(zhuǎn)體180度屈體跳再轉(zhuǎn)體180度成俯撐”和C479“轉(zhuǎn)體360度屈體跳再轉(zhuǎn)體180度成俯撐”兩個(gè)C組難度動(dòng)作各階段進(jìn)行測(cè)量，對(duì)所得數(shù)據(jù)進(jìn)行分析比較，深入探究其動(dòng)作原理，找出該動(dòng)作的正確技術(shù)要領(lǐng)和關(guān)鍵技術(shù)，旨在提高我國(guó)優(yōu)秀競(jìng)技健美操運(yùn)動(dòng)員完成高難動(dòng)作的完成質(zhì)量和改進(jìn)技術(shù)水平；通過(guò)選取C477和C479兩個(gè)根命名相

3、同的難度動(dòng)作，對(duì)其完成動(dòng)作技術(shù)原理和對(duì)身體素質(zhì)要求的比較研究，有助于高水平運(yùn)動(dòng)員選擇更適合自己的難度動(dòng)作。通過(guò)對(duì)比分析得出以下結(jié)論：1高重心和爆發(fā)力強(qiáng)是大幅度完成C477難度動(dòng)作的前提。起跳階段踝關(guān)節(jié)角度在40。～50。之間、膝關(guān)節(jié)角度在30?！?5。之間的充分緩沖將為后續(xù)蹬伸動(dòng)作的完成儲(chǔ)備較大的彈性勢(shì)能，以保證運(yùn)動(dòng)員充分展示空中姿態(tài)。2完成C477騰空時(shí)，水平越高的運(yùn)動(dòng)員，其髖、膝、踝關(guān)節(jié)角度越大，說(shuō)明其起跳充分并且有利于身體繞縱軸轉(zhuǎn)

4、動(dòng)；踝關(guān)節(jié)度角大，繃直腳面可體現(xiàn)競(jìng)技健美操的姿態(tài)美。3C477落地緩沖階段，主要是靠肘關(guān)節(jié)的緩沖和踝關(guān)節(jié)勾腳的支撐來(lái)完成，肘關(guān)節(jié)屈角為90。～110。、踝關(guān)節(jié)緩沖角度為25?！?0。時(shí)，運(yùn)動(dòng)員完成落地效果最佳。4C477和c479兩難度動(dòng)作在完成起跳動(dòng)作時(shí)發(fā)力時(shí)機(jī)和對(duì)技術(shù)要求不同。運(yùn)動(dòng)員完成C477難度動(dòng)作時(shí)先起跳再轉(zhuǎn)體，要求有較高的騰空高度，而完成C479不但要求足夠的騰空高度，在起跳前還需先完成髖部擰轉(zhuǎn)再起跳。5。完成C479時(shí)空中

5、轉(zhuǎn)體速度要比C477快，在一定的時(shí)間里，空中轉(zhuǎn)體速度快才能有足夠的時(shí)間去完成更多的空中動(dòng)作，快速的轉(zhuǎn)體對(duì)運(yùn)動(dòng)員腰腹力量和腿部蹬伸力量要求很高。AbstractDi伍cultymoVementofcompetitiVeaerobicsincompetitiVeaerobicsplaysanimpol乜【ntroleinsupportingbone：whichistheimportantmeasureofathletestechnicall
