The aim of this study was to describe weekly acute workload (wAW), chronic workload
(wCW), acute: chronic workload ratio (wACWR), training monotony (wTM), and training strain
(wTS) variations over a full season across playing positions. Twenty-one professional soccer players
were daily monitored during 48 consecutive weeks. Total distance, sprint total distance (STD), highspeed
running distance (HSRd), maximum speed, number of the repeated sprints, and body load (BL)
were obtained during training and matches using aWearable Inertial Measurement Unit. The wAW
was determined for each external load measure. The wCW, wACWR, and wTM were calculated
based on BL metric. Higher values of weekly STD were observed in lateral defenders/wingers
(LDW) compared to central defenders/forwards (CDF) (p = 0.009; ES = Large) and midfielders (MDF)
(p = 0.034; ES = Large). Additionally, weekly HSRd was higher in LDW vs. CDF (p = 0.016; ES = Large)
and MDF (p = 0.011; ES = Large). The CDF presented a lower weekly number of repeated sprints than
LDW (p = 0.021; ES = Large). In conclusion, weekly external load metrics were position-dependent
over the season. Moreover, LDW a presented greater weekly STD, HSRd, and number of repeated
sprints compared to other positions.
