ABSTRACT:
The aim of this study was to compare match analysis (using video recordings) and the physiological load (heart rate measured every 5 s, blood lactate measured after the warm-up, first half and second half) of six 11-year-old soccer players during official games of eleven-a-side on a regular-sized pitch (100 x 65 m) and of seven-a-side on a smaller pitch (60 x 40 m). In both games, heart rate exceeded 170 beats.min-1 84 % of the time, while blood lactate ranged from 1.4 to 8.1 mmol.1-1. No significant differences were recorded for the physiological parameters. For both matches, walking comprised 38 % of total time, running 55 %, inactivity 3 % and jumping 3 %. Although there were no significant differences between halves or matches, running for less than 10 s was 10 % more frequent in the seven-a-side game. In the seven-a-side game, there were significantly more passes and significantly fewer tackles, suggesting that seven-a-side matches played on smaller pitches may be more suitable for pre-pubescent soccer players.
