Different pitch areas of small-sided games for improving spatial dispersion, alter internal training load and technical-tactical skills in under-11 soccer players

Abstract

Objective: The current study investigated whether different small-sided game (SSG) pitch areas alter the spatial distribution, internal training load, or tactical-technical actions on the pitch of under-11 soccer players. Methods: The sample consisted of 18 male under-11 soccer players, randomized into 9 SSG groups, 3 vs. 3, who played without a goalkeeper, on SSG_small (12 x 28 m), SSG_medium (18 x 24 m), and SSG_large (24 x 30 m) pitch areas. The percentage of total pitch area occupancy, action area per player, peak (HR_peak) and mean (HR_mean) heart rate, Edward´s training impulse (TRIMP), tactical-technical actions, and game performance were evaluated. Results: The percentage of the total area occupied (p<0.05) and the action area (p<0.05) per player were lower in SSG_large (p <0.05). No differences were found in the HR_peak and HR_mean values ??between different SSG areas (p> 0.05). The TRIMP in SSG_large (p <0.05) was higher than in SSG_small. Changes in pitch dimensions increased the number of duels, ball possession, tackles, and receptions in SSG_small. Conclusion: We conclude that SSG_large increased the spatial distribution and internal training load of players, while SSG_small increased the number of technical actions.
