Research On The Age Characteristics Of Medalists In Summer Olympic Games From The Perspective Of Event-group Training Theory

By studying the age profile of current summer Olympic medalists,finds out the changing trend of the age of medalists in the Olympic Games,and then rises to the level of event-group,summarizes a series of characteristics of the age of medalists in different event-group,and enriches the content of training theory of event-group.This study used the methods of literature review,mathematical statistics,comparative analysis and expert interviews to study the age characteristics of medalists of the four summer Olympic Games from 2004 to 2016 from the perspective of the event-group training theory,the following conclusions can be drawn:1.The average age of medal athletes in the past four summer Olympic Games was 26.80 5.41 years for men and 25.41 4.70 years for women.The age range of 20 to30 years old is the main concentration range for medalists,accounting for about 70%of the total number of medalists.At this age,the comprehensive level of body functions in all aspects reaches the peak.2.The average age of medalists of the last four summer Olympic Games basically presents the fuzzy feature of accuracy > mesh antagonism > endurance >fast strength > combat antagonism > speed > difficulty and beauty.In terms of the characteristics of large categories,it is shown that the technical mind dominated >technical battle dominated > Physical dominance > skill dominanced.3.The increase of the average age of the medalists in the past four summer Olympic Games is mainly reflected in the increase of the average age of the medalists in the physical dominant category,the adversative category of netted separation,and the female difficult beauty category.The average age of medalists in the dominant category of skill and ability showed no obvious trend.4.For the male medalists,the age distribution ranges of the physical dominant category,the skill dominant category,the skill heart dominant category and the skill battle dominant category are 25-30 years old,20-25 years old,30 years old and above,and 25-30 years old respectively.For female athletes,the age distribution ranges of the above four categories are 20-25 years old,below 20 years old,25-30 years old and 25-30 years old respectively.It is suggested to strengthen the research on the training,management theory and method of high-level maintenance stage,increase the input of monitoring and medical security,and extend the sports life of athletes to the greatest extent.Attaching importance to the role of subjective morale in prolonging athletes' exercise life,athletes are encouraged to constantly challenge themselves through various ways.Accurately grasp the development direction of the project competition rules,comply with the rules and make full use of the rules.It is suggested that the time range be extended in the follow-up study to grasp the characteristics of the age change of medallist athletes from a longer perspective.
