| Using the literature data method,comparative research method,mathematical statistics method and video analysis and other research methods,the 31 st Rio Olympic Games in 2016,the 13 th National Games in 2017,the 16 th International Athletics Championships in 2017,2017 The athletic performance of the top three team athletes in the track and field world relay race and the 2018 Jakarta Asian Games track and field relay(4×100 meters,4×400 meters)competition is the research object.By analyzing,comparing and synthesizing the characteristics of the top three athletes in these five track and field relays,such as age,performance characteristics,reaction time,and relay skills and tactics,the following main conclusions are drawn:1.At present,the best athletic age of excellent male relay athletes in the track and field word is 22.75 ~ 26.10 years old;and the best athletic age of excellent female relay athletes in the track and field world is 22.00 ~ 28.30 years old.There is no significant difference in the competitive ages of male and female relay athletes in these five games.(P=0.702>0.05)2.Athletes of relay teams in track and field generally have a play rate of 100.14%during the season.There is no significant difference in the play rates of male and female relay events.The average play rate of male relay events is higher than that of women.The male and female relays showed good competitive performance characteristics with good championship results and small average coefficients of variation of the top three sports teams.There was no significant difference in the coefficients of variation of the average results of the top three teams of male and female sports teams.The stability of the average results of men's relay events is better than that of women.3.In the 4 × 100-meter hand-over technique,only the Japanese men 's team adopts the “up-pull type”,while the other teams use the “down-push type”.In the 4 ×100-meter relay,the 2017 Zhejiang National Games Beijing-Zhejiang-E-Guangdong men 's team and the Heilu Yuegui Second Women 's team were the teams that benefited most from the relay;of the 4 × 400-meter relay,the relay benefited most The men 's and women 's teams are Trinidad and Tobago in the 2017 World Championships and India in the 2018 Asian Games in Jakarta.The team that hasbenefited more time from the relay is because the athlete passes the relay zone faster and smoothly to complete the baton.4.In the 4 × 100 m relay,the technical characteristics of each player in the relay tactics of the Jamaican team,the Chinese team,and the British team are fully exerted.From the strength and experience,the top three teams of the Japanese team have arranged the best three The purpose of the players is to use the first three shots without mistakes and give the player with the last shot a lead.The US team placed the stronger players in the third and fourth shots.The first shot was a little weaker,while the second shot arranged a 100-meter special athlete.In the 4 × 400 m relay,the United States and Jamaican men 's team and the Polish women 's team have stronger second and fourth clubs,the first and third clubs are weaker,and the Jamaican women 's team have the first,second and third teams According to the requirements of the coaches and athletes,the position order is arranged,and the fourth stick arranges the stronger athletes.Judging from the results of the study,the current domestic competitive performance characteristics of excellent 4×100m and 4×400m relay runners are still different in terms of athletes' age,competition performance characteristics,reaction time,and relay techniques and tactics.In this regard,this study puts forward corresponding countermeasures and suggestions to provide reference and reference for the development of my country's track and field relay runners. |
