Abstract(s)
The purposes of this study were (a) to determine the variations in internal and external measures
of training monotony (TM) and strain (TS) in professional soccer players according to periods of the
season and playing positions, and (b) to analyze the relationships between internal and external
measures of TM and TS. Twenty male professional players (age= 29.4 ± 4.4 years) were followed for 20
weeks through session rating of perceived exertion (s-RPE), total distance (TD), high-speed running
distance (HSRD) and sprint distance (SpD). Regardless of measure, highest mean TM and TS scores
were observed in mid-season and end-season. In general, wingers and strikers tended to have greater
values in TM. Midfelders exhibited greater TS of TD and SpD. Correlation results for TM revealed that
s-RPE was positively associated with SpD in early-season (r= 0.608) and negatively associated in mid season (r = − 0.506). Regarding the TS, result demonstrated that s-RPE is negatively associated with
HSRD in early-season (r= − 0.464) and positively associated in mid-season (r= 0.476). In general, there
diferent meanings in correlations between internal and external measures across the season. On the
one hand, our fndings highlighted that TM and TS of professional soccer players is sensitive to period
of the season and player’s position, but on other hand, correlation analyses proved that changes in
one external/internal measure does not cause changes in another external/internal measure which
support the constant monitoring of these values across the season
