Background and Aim: Excessive daily Training load monitoring (TL) can affect musculoskeletal system health of youth elite soccer players. The purposes of this study were (i) to describe TL and session rating of perceived exertion (s-RPE) throughout competition season; (ii) to analyze the weekly (w) differences of acute (daily) workload (wAWL), chronic workload (wCWL), acute-chronic workload ratio, training mo-notony (wTM) and training strain (wTS) among three periods over the season (early-, mid- and end- season) by playing position; and (iii) to compare the TL variables during competition periods for the whole team. twenty young soccer elite players from Sepahan team in the Premier League in the 14-year category participated in this study. The game positions were considered as six wide defenders and wide midfielders (WM), five central defenders and central midfielders and four strikers (ST). Daily monitoring was continued for 26 weeks during a full competition season. According to the league schedule, the season was divided into three periods: early-season from w1 to w8, mid-season from w9 to w1, and end-season from w18 to w26. In conclusion, daily TL and s-RPE had meaningful fluctuations during all macro- cycles of competition season. Also, in the mid-season, wTM and wTS were higher and, among all playing positions, WM had meaningfully greater value of wAWL and wCWL compared with the other positions. Training load monitoring could be the key for coaches of soccer teams to prevent overtraining and injury, especially in U-14 players, who are more susceptible to get affected by high workload.
