Resumo
We aim to investigate the impact of variable soccer pitch sizes on the position of players during unbalanced
small-sided games (SSGs) and compare the responses of players from two different age groups. Forty-eight
young players (n = 24 under-13 and n = 24 under-14) took part in the study and played 3 vs. 3 + 1 SSGs on
two different pitch sizes (smaller: 36 x 27 m / 139m2
per player; and larger: 40 x 29 m / 166 m2
per player).
Players’ positions on the pitch (length, width, length-to-width ratio, stretching index, and spatial exploration
index) were assessed by the positional data provided by global position system devices and were compared
within age groups and between game formats using a two-way analysis of variance. Results showed higher
values of spatial exploration index (SEI) in the larger SSGs than in the smaller format (p<.001). Moreover, a
higher length (p<0.001) and length-to-width ratio (p<.001) was observed in the younger group. Finally, the
larger format presented higher values of SEI and stretching index, independent of the age group (p<.001). In
the smaller format, U-14 players presented a higher stretching index, while in the larger format U-13 players
presented higher values in the same variable. We conclude that enlarging the pitch size constrains players’
behaviour during SSGs, and older players are more able to deal with this more complex task context than
younger ones.
