Research On The Distribution Of Contrast About Blood Type And Gene Frequency Of High-level Athletes And Non-athletes In Different Sport Events

Human's blood type depends on genic heredity,and the heredity grade is 100 percent.In the 21 st century,the excellent scientific and technological achievements are utilized widely in various fields with the huge technological advances.Not only the scientific ways that coach choose the athletes have become more and more mature,but also the selection indexes of sport talent in different sport events have become perfecter and perfecter.The relevance between blood type and athletic ability has become one of the research contents because of heredity characteristic of blood.In recent years,there were various researches about blood type and specific sport events,which had great divergences among them.The divergences were divided into two categories:some scholars believed that there was necessary connection between blood type and specific sport events.The others believed that there was not necessary connection between blood type and specific sport events for blood type is the difference of red blood cell antigen among the individuals,which would not influence the sport performance of athletes.Although there were many researches about blood type and physical quality,they did not have the holistic representativeness as most of them were just studied on one sport event which could just illustrate the characteristics of distribution of blood type and the relevance between blood type and sport event for single item.The main research methods of this paper include the method of documentary,interview method,test method and mathematical statistics method.Based on Chinese famous scholar Tian Maijiu's event-group theory,athletes of one or multiple sport events from each event-group were chosen for this research.Testing the blood type of the athletes,analyzing characteristics of distribution of blood type and gene frequency of each athlete,comparing with non-athletes and then to judge whether there is necessary connection between blood type and every specific sport event.There are results as follows:1.Each event-group athlete's distribution of blood type is different from non-athlete's.According to chi-square test,the blood type P-value of event-group of grapple,the net sports,performance accuracy is less than 0.05 with obvious difference.Meanwhile,the blood type P-value of speed,antagonism in the same court,antagonism of grapple is more than 0.05,there is not obvious differencebetween event-group athletes and non-athletes.It shows that there is necessary connection between blood type and every specific sport event in different degrees.2.Each event-group athlete's distribution of gene frequency is different from non-athlete's.According to chi-square test,P-value of all event-groups are more than0.05.Therefore,there is not obvious difference between the event-group athletes and non-athletes.It can be believed that there is not necessary connection but different characteristics of distribution between the event-group athletes and non-athletes.3.Combining the research results of the blood type and the athletes' physical quality with characteristics of different sport events,to analyze the cause and then to find the most appropriate blood type for each sport event so as to offer reference for choosing athletes,to provide suggestions and psychological hint to public physical training about choosing suitable sport events,and then to enhance positivity of people to participate body-building.
