Abstract
The aims of the study were: 1) to analyze the exercise intensity in several
phases (six phases of 15 min) of soccer matches; 2) to compare the match time spent
above anaerobic threshold (AT) between different age groups (U-17 and U-20); and 3)
to compare the match time spent above AT between players’ positions (backs, midfielders,
forwards and wingabcks). Forty-four male soccer players were analyzed. To express
players’ effort, the heart rate (HR) was continuously monitored in 29 official matches.
Further, HR corresponding to the intensity at the onset of blood lactate accumulation
(OBLA) was obtained in a field test. The highest exercise intensity during match was
observed in the 15-30 min period of the first half (p< 0.05). Match time spent above
AT was not different between players from U-17 and U-20. In the comparison among
players’ positions, wingbacks showed lower time above AT (p< 0.05) than players of other
positions. The intensity of effort is higher in the 15 to 30 minutes of play (intermediate
phase), probably because the players are more rested in the beginning and wearing out is
progressive throughout the game. It is also noteworthy that the intensity of exercise (HR
and time above AT) of wingbacks was lower, probably because they usually are required
to run a larger number of sprints and need more time below the AT to recover.
