Abstract
The Brazilian soccer season is structured throughout the year and is characterized by well-defined periods, such as the preseason and in-season periods. This study analyzes the dynamics of internal training load in professional soccer players during preseason. Twenty-three male professional soccer athletes participated and were monitored over 4 weeks of training. During this period, perceived recovery status (PRS) was assessed using the perceived recovery status scale, while internal training load was determined using the session rating of perceived exertion (session-RPE) method. During preseason, PRS ranged between 4 and 7 arbitrary units (AU), while intensity across weeks remained at moderate levels (4–6 AU). Mean PRS, session-RPE, and training volume differed across weeks (p < .05), with lower values in weeks 3 and 4. Internal training load decreased in week 4 compared to previous weeks (p < .05), while monotony and strain were highest in week 3 and differed from other training weeks (p < .05). Professional soccer players are exposed to moderate training intensities and recovery perception during preseason, with sessions mostly lasting less than 90 minutes. Regarding internal training load dynamics, monotony, and strain, athletes reported an increase over the first three weeks, followed by a reduction in the final week.
