I摘 要本文采用文献资料法、数理统计法与对比分析法对 2013 版及 2017 版 FIG 规则有关难度方面进行研究，从难度动作的数量及根命组/名、分值分布、减分情况、难度动作连接调整四个方面进行比较分析，总结出 2017-2020 版规则，在难度方面的发展趋势。结果显示：2017-2020 版规则，难度动作有所减少，分值高的难度动作明显再增多，减少的大多是低分值的难度；总体来看新版规则高分值难度动作的提高提升了竞技健美操的竞技性与观赏性。对新规则的分析显示出难度动作的变化趋势以及发展规律，为教练员提供新周期规则难度动作的技术指向，有利于运动员训练、比赛时达到更好效果。关键词：竞技；健美操；规则；难度动作；对比IIABSTRACTThis paper uses the methods of literature review, mathematical statistics and comparative analysis to study the relevant difficulty aspects of the 2013 and 2017 FIG rules, and makes comparative analysis from four aspects of the number of difficult actions and root life groups/names, score distribution, points reduction and adjustment of connection of difficult actions, and summarizes the development trend of the 2017-2020 rules in the difficulty aspect. The results show that in the 2017-2020 version of the rules, the difficulty moves are reduced, the difficulty moves with high scores are obviously increased, and the reduction is mostly the difficulty with low scores; Generally speaking, the improvement of high-score difficult movements in the new version of the rules has improved the competitiveness and appreciation of competitive aerobics.
