abstract = {The purpose of this study was to analyze the intragroup differences in weekly training
monotony (TM) and training strain (TS) between starter and non-starter male professional soccer
players at accelerometry based variables throughout the periods of a season. TM and TS of different
accelerations and decelerations zones for twenty-one players were followed for forty-eight weeks.
Regardless of group, players obtained the highest mean TM (starters = 3.3 ± 0.6, non-starters = 2.2 ±
1.1, in arbitrary unit, AU) and TS (starters = 1288.9 ± 265.2, non-starters = 765.4 ± 547.5, AU) scores
in the pre-season for accelerations at Zone 1 (<2 m/s2). The results also indicated that both groups
exhibited similar TM and TS scores in accelerations at Zones 2 (2 to 4 m/s2) and 3 (>4 m/s2) across
the entire season. While the starters showed the highest TM and TS scores at deceleration Zone 1
(<−2 m/s2) in the end-season, the non-starters exhibited the highest scores at the deceleration Zone
1 in pre-season. It seems that in pre-season, coaches applied higher levels of training with greater
emphasis on deceleration for non-starters. This tendency was reduced over time for non-starters,
while starters presented higher values of deceleration Zone 1. These results highlight the variations
in TM and TS across the different periods of a full season according to match starting status among
professional soccer players, and the results suggest that non-starter players should receive higher
levels of load to compensate for non-participation in matches throughout a soccer season.},
