| Xie Zhenye,one of the key national team members of China National Men's Dash Team,was a 2016 master's candidate at Zhejiang University.He was born on August 17,1993,with a height of 183 cm and a weight of 78 kg.As of now,he has successively created 100 meters 10.04 seconds and 200 m 20.20 seconds,4×100 m 37.90 seconds of personal best,is an excellent man sprinter.Based on the previous studies and based on the main characteristics and rules of the special sprint meters,this paper uses Xie Wenye 's personal characteristics,body functions,main technical indicators and the methods of literature review,expert interviews,comparative analysis,mathematical statistics and other methods Physical training composition and other aspects of analysis and research,the conclusions and recommendations are as follows:1.Xie Zhen industry into the national sprint team fought 100 meters from 200 meters,two special results have been significantly improved,respectively,20.20 seconds and 10.04 seconds in the National Games to refresh their own record,indicating that the athlete with a strong sprint Special ability and overall quality;Xie Zhen 183 cm,78kg height and weight compared to other excellent players in our country have some special advantages,Xie Zhen industry Kettlei index was 426.23,height 195 cm body weight 94 kg Bolt was 482.05,significantly lower than Bol special.Suggest Xie appropriate amount of industry to increase lean body mass,increase the body's ability to work to further improve the sprint special physical fitness;2.Preparation for the National Games stage Xie Zhen before and after winter training BUN,HGB,WBC,CK,T and other indicators of the comprehensive assessment results show that: the indicators of cyclical changes within a reasonable range to adapt to the training load arrangement,after winter training T,HGB All improved and body functions improved further.The indexes such as BUN,WBC and CK showed that there was no symptoms of unwell or over-fatigue at the end of the winter training period and were suitable for special competitions.3.Xie Zhenye pace index maintained at a high level,compared with Bolt step index is lower,there is greater room for improvement.Xie Zhenye full speed curve appeared dual peaks,while Bolt tends to accelerate the latter part of the smooth dam type;Bolt speed peak appears in 60-70 m acceleration process,Xie Zhenye maximum speed peak appears in 40-50 m acceleration process,The first 30 m speed acceleration too fast,will continue to accelerate the follow-up will have a negative impact.4.Xie Zhenye single-step running posture,the overall stage of support than the pedal stage knee angle to maintain better,after the pedal is not sufficient enough,in the ground,cushioning and pedaling stage should pay attention to the overlap of the swing leg.Under the condition of constant stride frequency,the folding amplitude of the rear leg may be a hidden factor that limits the step of Xie Zhenye.5.Suggestion: Due to individual differences,step size and pace frequency have different personal characteristics.It is suggested that Xie Zhenye pay more attention to the step-by-step technology related to step-backs on the basis of keeping the step frequency stable.Is to accelerate the rhythm of the first 30 m,the rational distribution of physical fitness,and gradually over to the maximum acceleration phase;targeted to strengthen the relevant strength and flexibility training in the special training process to strengthen the leg during the leg swing after the fold rate,thereby increasing Its special grade. |
