安徽省高校竞技健美操单人项目难度动作研究——以安徽省第十三届省运会为例

On the Difficult Movements of Individual Item in Competitive Aerobics in Anhui Universities:Exemplified by The 13th Sports Meeting of Anhui Province

通过实地观察、录像分析、专家访谈等方法，从难度分值、难度组别、难度动作运用频数及得分成功率等方面，对安徽省第十三届运动会高校部竞技健美操单人项目14套动作中的140个难度动作进行统计分析．结果表明：1）难度分整体不高，对难度动作分值的选择集中在0．3～0．6，难度分的高低是获得比赛胜利的重要基础；2）难度动作选用单调，重复率高，组别选用不均衡，以C类（跳跃类）为主；3）难度动作得分成功率低下，动作稳定性有待提高．

140 difficult movements from the 14 sets of competitive aerobics individual item in The 13th Sports Meeting of Anhui Universities are statistically analyzed from the aspects of difficult points ,difficulty sorts ,application of frequency and the success rate of completion in difficult movements by the way of field observation ,video analysis ,expert interview and mathematical statistics method .The results show that the difficulty points are not completely high ,the difficulty points concentrate between 0 .3~0 .6 ,and the level of difficulty points is the essential part of the victory .The types is drab , repetition rate is high ,the difficulty sorts are disequilibrium ,and the class C is the only priority .The success rate of completion is low ,and the stability needs to be improved .
