The Research On The Aerobic Step Complete Movements Under The New Rule In 2017-2020

The aerobics scoring rule is a statutory document for aerobics competition.Its purpose is to ensure that the referee's rating is objective and uniform during the competition,so that the referee's professional knowledge and refereeing ability are improved,and in the course of daily training and competition,Athletes and coaches provide guidance.With the continuous revision and improvement of the rules,the aerobic step is gradually returning to the project itself.Therefore,under such a large-scale change in the 2017 version of the rules,it is necessary to study the new and old rules and complete sets of actions.This article is based on the "2013-2016 Competitive Aerobics Rating Rules"(hereinafter referred to as "2013 version of the rules")and "2017-2020 Competitive Aerobics Rating Rules"(hereinafter referred to as the "2017 version of the rules"),using documentary methods,expert interviews Law,questionnaire survey,video analysis,mathematical statistics,and comparative analysis,for the 2016 World Aerobics Championships(hereinafter referred to as the "2016 World Championships")and the 2017 World Games Oxygen Pedal Final(hereinafter referred to as "2017 World Games The meeting will conduct research on the complete set of actions,summarize the development trend of the project under the rule change,deepen the understanding of the new rules,and explore the development direction of the aerobic step set of actions.The conclusions of the study are as follows:1.The complete music style tends to combine the two music styles;the music speeds up;the passage of music increases,and the paragraph structure is clear.2.60%of the participating teams have increased the number of sets of A+ operations;in terms of the type of pace used,the use rate of the upper plate points/down plates,kicks,and suction legs has reached 100%,and the pace of competitive aerobics has taken a step.The frequency of appearances of kicks,kicks,and opening and closing hops increases at the set pace;the amplitude of arm movements increases,complexity and diversity increase,and there are more operations for referees.3.dynamic cooperation has become the main expression of the companionship in the complete set of actions;the number of transitional connections and lifts has gradually decreased,but the complexity of the movement has been improved,the diversity has increased,and the transitional connection has changed in space in the C space;In the way of changing boards,there are three new types of board changing methods:push boards,slide boards,and single-foot switch boards.4.The complete set of space transformation tends to be complex and diverse;on the premise that the number of formations decreases,the transformation of the formation speeds up;video analysis concludes that the formation of team formation is mainly divided into four types:symmetrical,asymmetric,decentralized,and aggregated.Among them,the use of symmetry is the most.5.Most of the teams' quality of artistic creation is higher than the quality of complete sets of actions.However,the quality of the complete set of the Chinese team is higher than that of the artistic creation;the costumes of the competition are dominated by the darker colors,and the bright colors are supplemented;the player's gender is dominated by the female athletes.Change to a mixture of male and female athletes.
