Research On Match Load Characteristics Of Chinese Male National Rugby Sevens Team

Purpose:In order to providing a reference for scientific training,this paper makes an analysis about Chinese elite male Rugby sevens players' match load who attended the Rio Olympic qualifying game in 2016 year by analyzing the characteristics of running,physical confrontation and heart rate in the match.Research method: The research object contained 12 key Chinese male Rugby sevens players(5 forwards,7 backwards).Applying Catapult sports system and Fristbeat system to collect data,and using SPSS17.0 statistical software to analyze the data.Result:1.The total running distance of Chinese national male seven rugby player is 1481.8±181.1m,including 149.3±33.7 m sprints,222.5±47.0 m high intensity running.The average heart rate and maximum heart rate were 172.2±8.6 times,185.9±6.7times,respectively.The percentage of > 80% of the HRmax is 84.4±13.3% of the total game time,and the percentage of 81-90%HRmax and >91%HRmax were 43.3±22.3%,41.4±29.5%,respectively.2.Chinese national male seven football player needs 7.1±1.1 sprints per game,and the maximum speed is 28.3±2.4km/h,the average sprint distance is 20.4±5.6m.Moreover,the average change of direction is 141.0±34.3 time,including 18.2±6.5 high intensity COD.3.As for sprint distance,high intensity distance,sprint times,maximum sprint distance and high intensity COD,there are significant difference between the first half's and second half's.4.As for running characteristics,physical confrontation and heart rate,there are no significant difference between forward and backward.5.Overall,bench player's match load is slightly higher than the athletes who were attending a whole game.Conlusion: Chinese national male seven football player' games have a high intensity,and players need to have a high intensity running ability and body confrontation ability;2.Chinese national male seven football player needs a good speed skill and agility skill.3.There is no obvious difference between forward and backward,and this characteristic requires player has an ability to work as different position.
