Table 3: _Cont._no doubt about the need of knowing training load progression and variations throughout time. Interestingly, training heterogeneity could contribute to differences between playing positions and the variation of ACWR along the season since ACWR measures sensitivity to distinct periods (i.e., congested or normal ones). Naturally, those variations and differences may depend on the derived-GPS parameter considered. This idea is supported by the outcomes presented into this manuscript that show coefficients of variations from 15 to 37% in the different derived-GPS parameters assessed, being especially higher for parameters referred to the high-intensity efforts or actions performed by players. It is well-known that high-intensity demands differ between playing positions. Curiously, we did not verify differences for the wAW, wCW, wTM, and wTS based on the BL metric between playing positions. In contrast, a previous study reported greater values of wAW and BL for the defenders (124.1 \(\pm\) 114.1 AU), midfielders (153.9 \(\pm\) 125.4 AU), and forwards (107.5 \(\pm\) 60.3 AU) compared to our results [63]. The contrasting findings can be explained by the different training tasks applied over the season [8]. Further studies, including the training content, are warranted to clarify the workload doses throughout the season, which will enable future comparisons between studies [64,65]. Here, wTD did not differ between playing positions over the season. We found lower values of wTD (3.842 m-3.587 m; Table 3) compared to previous studies that reported values of wTD of ~4.500 m in Spain [22], ~5.000 m in the Netherlands, and ~7.000 m in Portugal [66]. The possible explanation of the divergent results can be related to the playing styles, coachs' decisions for designing drills, and competition demands across leagues [67]. In addition, our results revealed greater values of wSTD, wHSRd, ratio STD/TD, and HSRd/TD for LDW compared to CDF and MDF. [PERSON], [PERSON], [PERSON], [PERSON], and [PERSON] [22] also observed that wide positional roles presented significant high-speed and sprint activities during the training and match sessions. These specific positional physical demands may be related to the constant attack and defensive functions during the training sessions as well as match-play [58].
