Comparative Study On Arrangement For Secondary Compulsory Exercises For The Single Aerobics Of Athletic Aerobics

As the object of study on arrangement for secondary compulsory exercises for the single aerobics of athletic aerobics in version 2005 and 2009, the detailed comparative study is performed on four sets of secondary compulsory exercises for the single aerobics of athletic aerobics in version 2005 and 2009 by the means of document literatures, observation, comparison and mathematical statistics according to requirements of the Rules of Competition of FIG2009-1012 Athletic Aerobics under the development trend of arrangement of the international athletic aerobics exercises.The research results show that the Version-2005 secondary compulsory exercises for the single aerobics of athletic aerobics have the following characteristics:(1) Music materials are based on songs with characteristics of our ethnic groups and foreign popular songs, mainly in the style of rock and roll. The changes of the beat of music are three and seven times, which has no difference in comparison with that of foreign countries. The speed of music is 26 beats and 28 beats per second, which is in conformance with our current situation; (2) Higher complete set of complicated gymnastic movements, but there are some shortages in the distribution balance of application and gymnastic movements for the shapes of hands; (3) The transition and connection movements are mainly simply rising and kneeling in bow steps, and excessive repetitions; (4) more forward, left and right applications for the competition course; (5) The space transfers are mainly to complete A-B, B-A, B-C-B and B-C-A, with simple types and high repetition but short of diversity; (6) Lower coefficient for the complete sets of difficult parts with simple movements. The difficult value for the arrangement of difficult parts is lowered with the time. The Version-2009 secondary compulsory exercises for the single aerobics of athletic aerobics have the following characteristics:(1)The more perfect music selected in coordinate with movements; the changes of music rhythm increase, and artistic quality and appreciation of the whole set movement upgrade; the rational music speed is in favor of the sportsmen to seize the rhythm of movements and music to improve the standard movements; (2)keeping multifarious gymnastic movements, and strengthen the balance of arrangement of the whole movements; (3)A relative balance times of space transfer types with great difficulty, which has a high requirement for athletes'physical ability and artistic expressive force; (6) Levels of difficulty presents rising trend, with better layout for arrangement of difficult parts.According to above research results, some suggestions are set forth in this paper after detailed comparison and analysis are conducted on arrangement for secondary compulsory exercises for the single aerobics of athletic aerobics:(1)Highlighting the diversity, smooth and balance of the whole set of movements in arrangements; (2) Increasing the transfer times in gymnastic movements, and adjusting transition and connection in the whole set of movements, and occupation ratio of space transfer of difficult movements in the three-dimensional competition court; (3)Controlling rationally the time of transition and connection in the whole set of movement, and attaching importance to artistic effect of transition and connection in the whole set of movements.
