Research On The Model Building Of Special Physical Fitness Of Aerobics Athlete Of Excellent Women's Athletic In China

Under the change of new rules requires higher physical ability of female competitive aerobics athletes,scientific training improvement and evaluation of physical fitness gets more important.Therefore,only by objectively evaluating the special physical fitness of female competitive aerobics athletes and implementing effective monitoring can comprehensively improve their competitive ability.This paper uses the methods of documentation,Delphi,logical analysis,mathematical statistics and other research methods,and combines theory with practice to screen out practical and easy-to-operate special physical fitness indicators,and scientifically constructs a structural model of special physical fitness indicators for China's outstanding female competitive aerobics athletes.The research conclusion is as follows(1)The characteristics of competitive aerobics:Competitive aerobics is mainly based on anaerobic metabolism.It is featured with high intensity,short time and fast speed;Competitive aerobics is difficult,complicated in skills and varied in changes.Competitive aerobics requires the accuracy,comprehensiveness,artistry and innovation of movements.(2)The special physical fitness structure of female competitive aerobics athletes includes three aspects:body shape,body function and sports quality.Body shape can be summarized as follows:body height is symmetrical,muscle lines are slender,body weight is light but with strong muscle strength.The energy supply for the physical function of this project mainly relies on anaerobic metabolism.According to the technical characteristics of the project,the sports qualities must be possessed:fast strength,strength endurance,anaerobic endurance,flexibility quality,sensitivity and coordination ability.(3)The principles of constructing the special physical fitness index system are scientific principle,hierarchical principle,simplicity principle and combination of qualitative and quantitative principles.(4)The body shape indexes in the three-level indexes of special physical fitness of competitive aerobics include:height,weight,body fat rate and length of arms and legs Physical function indexes include vital capacity,heart rate and anaerobic power.The indexes of athletic quality include:Straddle jump 30,hip lifting 30,handstand lifting 15,supine abdominal muscles for 1 min,shuttle run for 2mins,gymnastic exercised(8X8),vertical fork(left and right)30cm,horizontal fork 30cm,shoulder joint(positive and negative)90°,and anterior flexion(split and combined)30cm.(5)China's elite female competitive aerobics athletes' special physical fitness structure consists of three parts:body shape,body function and athletic quality,which are influenced by each other.There are 10 main factors affecting the three parts,including height,muscle composition,length,cardiopulmonary function,anaerobic power,rapid strength,strength endurance,anaerobic endurance,sensitivity and coordination ability and flexibility quality.
