A review of soccer training load research based on quantitative data

This paper provides a systematic review of the external load of soccer training as well as multiple internal load characteristics quantified by the GPS system to provide a reference for training load arrangement and monitoring for seasonal programs.The results show that the total running distance of soccer training, high-speed running load is much lower than the game load, and the difference between acceleration and deceleration and the game is smaller; the training load has an inverted U-shaped distribution within a week; the training load decreases significantly in the late season; there are positional differences in training loads, with higher running loads for wingbacks and midfielders; the difference between non-starters and starters in total training hours and running distance is not significant, but there is a problem of insufficient high-intensity load; the load is higher in the pre-season preparation period due to longer training time and more training sessions.It is suggested that coaches and researchers should strengthen the monitoring of training load, clearly grasp and understand the characteristics of load distribution and adaptation mechanisms and arrange the training load scientifically according to the competition condition, cycle characteristics and other factors to guarantee the sports performance during the competition.
