Abstract: Objective:To explore the characteristics and training effects of resisted sprint and assisted sprint training load in different training stages of elite sprinter Su Bingtian in one season.Methods:The training load parameters of resisted sprint and assisted sprint in different training stages of Su Bingtian in 2018 season was tracked and recorded,then the Microsoft Excel 2016 software was used to compare and analyze the data.Results:1) The 17.1%~37.1%BW resistance load and 5~20 m practice distance were mainly used to improve Su’s starting ability,and a resistance load of 10%~17.1%BW and a practice distance of 30~40 m were used to improve Su’s acceleration ability;2) The 8.6%~10%BW power load,86.4%~99.1%V_maxpower speed and 20~40 m traction distance were used to improve Su’s running stability during the maximum speed;a 8.6%BW power load,99.1%~102%V_max power speed and 20 m traction distance were used to improve Su’s maximum speed capability;3) The commonly used resistance load in auxiliary training was 2.9%BW,the training distance was 40~45 m,and the resistance load of small hurdle running was9%~11.4%BW and the training distance was 30~50 m.Conclusions:The resisted sprint and assisted sprint training improved the starting,acceleration and acceleration abilities of Su Bingtian in the 2018 season.According to different training stages and the specific requirements,the systematacially and alternately arrangement of resisted sprint and assisted sprint training were the main reasons for Su Bingtian to make breakthrough in both 60 m and 100 m sprint in 2018 season.
