A Comparative Study Of The Body Morphology And Special Physical Ability In Adolescent Cyclists With Good Cyclists

Research purposes: By comparing the adolescent cyclists with good man cyclistsin the body morphology and the special physical ability, good athleticism and sportingpotential suitable for teens engaged in cycling and reserve force for selection to thecultivation of the system and its development trends. In order to select the cyclists andcultivate excellent athletes for sports school coaches make some reference.Research Methods: This paper takes SuZhou second sports school six adolescentcyclists and six good man cyclists in LiaoNing province as the research object, uses theliterature material method, experiment method and the methods of mathematicalstatistics. And the comparison research institute selected morphological indicatorsincluding height, weight, Quetelet index, ankle circumference/tendon length x100;Function indicators including HRmax, vital capacity, VO2max,10s average work,Testosterone(T), Cortisol(C) and Creatine Kinase (CK);Quality indicators includestanding long jump and15s cycling frequency; Special indicators including200m and20km road test.Research Results:1. there is no significant difference level comparison of Quetelet index in Bodymorphological, without statistical significance(p>0.05);Two groups of objects of anklecircumference/tendon length x100index less significant difference level, there is nostatistical significance(p>0.05).2. The function index of two groups of objects under the limit load thecomparison of HRmax, with significant difference level was statistically significant (p <0.05);The comparison of vital capacity has the significant difference level, wasstatistically significant (p <0.05);VO2Max (indirectly) less significant difference level, no statistical significance (p>0.05);10s anaerobic compared with the average amountof work it is very significant difference level, was statistically significant (p <0.01);Thecomparison of serum Testosterone has very significant difference level, was statisticallysignificant (p <0.01);The comparison of serum Cortisol has very significant differencelevel, was statistically significant (p <0.01);The comparison of serum Creatine Kinasehas no significant difference level, no statistical significance (p>0.05).3. The quality index of the comparison of two groups of objects standing longjump, with significant difference level was statistically significant (p <0.05);comparedof15s cycling frequency was very significant difference level, and statisticallysignificant (p <0.01).4. Two groups of objects in200m road test comparison with very significantdifference level, was statistically significant (p <0.01);20km road test compared withthe timing of it is very significant difference between levels, was statistically significant(p <0.01).Research Conclusion:1. From the point of view, body morphology indices for teenagers when selectmaterial, Mr Index can be used as the reference, the individual index and anklecircumference/tendon length x100index, the coaches should pay attention to trainingathletes is the development of the lower limb strength and short type into space, ordevelopment of the lower limbs aerobic ability and develop into a more long distancetype player.2. In terms of function index, the coaches should consider when select material forteenagers what they can achieve max exercise when the training is relatively high heartrate, and VO2max capacity should be close to elite athletes. And vital capacity level,coaches in lung capacity level of adolescent athletes when select material typicallyrequire higher than ordinary people. In addition, the serum Testosterone and Cortisoland Creatine Kinase three main reference index of serum Testosterone level indicators,and the serum Cortisol and Creatine Kinase as auxiliary conditions for reference.3. From two quality indexes namely, standing long jump and15s cyclingfrequency and combined with20km road test,200m road test results, the coach had to consider when select material the basis of lower limb strength and aerobic capacity.Even, in the future training strengthen the training of the lower limbs of special strengthand improve the cycling technology.
