| "Difficulty" is the core competitive factor of the aerobics gymnastics program.The difficulty level is an important factor in determining the ranking of the game.The clever and reasonable difficulty arrangement is the premise of maximizing the difficulty value of the complete set,and also a reflection of the complete set of artistic features.Five-person event is the single item with the most people and the most complicated action arrangement in the five competitive games.Along with the constant changes of the rules,the technical level of the difficult movements of the five-person operation project is also continuing to develop,and the difficulty action arrangement concept and development trend are also constantly updated.Through the comparative analysis of the competitive aerobics scoring rules in the last two competition cycles,combined with the difficult action arrangement features of the three-time World Championships excellent five-person team in two cycles,trying to find the logic between difficulty programming and rule changes Relationship,and then more accurately grasp the layout trend of the difficult action of the five-person program.This paper takes the 2017-2020 version of the rule to guide the difficulty movements of the aerobics gymnastics five-person as the research object.Using the literature data method,the scoring rules of each competition cycle,the literature on the set of difficult movements of competitive aerobics are collected and summarized and summarized as the theoretical support of this paper.Through video observation and technical statistics,the elements of group selection,score selection,space application,etc.of the excellent five-person set of difficult movements of the last three World Championships were recorded,and the mathematical statistics method was used for calculation and integration.Finally,through comparative analysis and logic analysis,the collected data and the literature are logically reasoned,and the following conclusions are drawn:1)The total number of difficult actions in the 2017-2020 version of the rule has been reduced,and the adjustment of the difficulty action scores has risen and fallen.Itis important to encourage athletes to challenge the newer and more difficult difficulty actions,and to delete some of the difficulty root names that are not commonly used.The root naming category of some difficult actions is adjusted to build a more scientific and reasonable difficulty system.2)The 2017-2020 version of the rule reduces the number of difficulty for the five-person program from 10 to 9.The difficulty group is adjusted from 4 to 3,and the technical difficulty of the athlete is fully exploited while the difficulty is required.Connection and difficulty skills are mixed to encourage diversified and innovative movements.3)The five-person sports aerobics program will continue to focus on the C group,while the choices of the A,B,and D groups will pay more attention to the individual characteristics of the athletes,and the difficulty of the C group will become more team opening.And the end is preferred.4)The selection of difficulty action scores is mainly concentrated between 0.6and 0.8 points,and gradually develops to 0.9 and 1.0 points.The difficulty score ordering will develop in a more reasonable and challenging direction,and the 100%difficulty completion rate is The key to getting high scores.5)The space application of the difficulty action will develop towards B-C-A and A-C-A,while the B-C-B,A and B space types will decrease,and the difficulty connection will develop towards a more cost-effective three-connection and difficulty skill hybrid connection.6)acute angle support and reverse cut,hip lift;,flexion jump,cossack jump,scissor jump,longitudinal leg jump,illusion and Horizontal control leg swivel becomes the high frequency action in the five-person event in the new cycle. |
