| Since the first World Sports Aerobics Championships held in France in 1995, the championships has reached 13th so far altogether due to the thriving growth of sports aerobics. With the rapid development of the sport and the advancement of athletes’sports level, the original rules aren’t suitable anymore, so the FIG (International Gymnastics Federation) has applied the policy of revising the rules every four years. Each time the revision has changed the rules of mixed pair to a certain degree and propose new inquires. The research applies the method of documentary, comparative analysis, video observation and expert interviews to analyze the specific changes in mixed pair in each set of rules and conclude the characteristics of the rule changes through making comparisons among the 4 different sets of rules from FIG2001-2013. On this basis, the thesis will discuss the influences that sports aerobics’rule changes have on composing complete sets of action in mixed pair in world championships combining with the composing complete sets situation of mixed pair winners from 7th-13th World Sports Aerobics Championships, aiming to develop the sports level of our national mixed pair sports aerobics.The main changes in sports aerobics rules in FIG2001-2013 and the influences the changes have on composing complete sets of action in mixed pair:Artistic score:The main changes of Artisticthe score are time reduction of complete sets of action in mixed pair; the expansion of the playing field; a more scientized,more reasonable and clearer scoring system; the highligts of artistic value, creativity and visual art; the reduction of lifts. These changes have led players to pay more attention to the proportionality and innovativeness when compose the complete sets of action. To get higher scores, it is better to highlight the gymnastic content, and use unbalanced upper limbs rather than balanced ones and single foot than two. Varied formations and large moving areas will also create a streching space for mixed pairs. In terms of lifts, all athletes are pursuing for difficulty and creativity. Due to the above changes, the composing of complete sets of action are on a way to become more artistic and creative.Difficulty score:The main changes of Difficulty score are the classification of difficulty groups is more scientized and refined while being in stability, showing the characteristics of diversification and complexity. The based names are more normalized and the values of difficulty movements are also changed. High value movements have increased while low value ones decreased, manifesting a tendency of pursuing high difficulty. The changes in difficulty score urge mixed pair athletes to choose movements valued in a range of 0.5-0.8 in order to improve the value of the a complete set of action. In difficulty groups, movements in C group are obviously more than movements in other groups; B group movements are the least and the value of D group movements has increased. The movement techniques tend to be highly difficult, which has led the difficult movements to develop in an orientation of diversification, complexity, normalization and high-difficulty.Execution score:The main changes of Execution score are the score reduction in consistency has been strengthened and higher requirements are demanded in the execution and consistency thus to highlight the importance of execution. The changes have led the athletes to attach more importance to the accuracy and quality of the action in world championships. |
