Abstract(s)
The purpose of this study was two-fold: (1) to describe weekly average values for training
monotony (TM) and training strain (TS) and their variations across the full soccer season, based on
the number of accelerations and decelerations; (2) to analyze the di erences between starter and
non-starter players on weekly average TM and TS values for the pre-season and three in-season
periods. In total, 21 professional soccer players were evaluated over 48 weeks during the full-season.
The TM and TS were calculated based on the number of accelerations and decelerations at zone 1,
zone 2 and zone 3, respectively. The results revealed that starters presented higher values compared to
non-starters throughout the full season for all variables analyzed (all, p < 0.05). Generally, there were
higher values in the pre-season. Specifically, accelerations at zones 1, 2 and 3 revealed moderate to
very large significance of the starters compared to non-starters over the full-season. Decelerations
at zone 1, 2 and 3 presented moderate to nearly optimally significant greater weekly averages for
starters compared to non-starters during the full season. In conclusion, the TM and TS values were
higher for starters compared to non-starters through the full-season, which confirms that the training
session does not provide a su cient load to non-starter soccer players during the full-season.
