Physical Performance During Soccer-7 Competition and Small-Sided Games in U12 Players

Abstract

The aim of this study was to compare the activity profile (external loads) during soccer-7 competition versus 6 vs 6 small-sided games ( SSGs) in U12 players. Peak velocity (V_max), total distance completed (DT), total distance relative to match duration, the percentage of DT in acceleration (%DAC) and in deceleration (%DEA), and the percentage of DT at different speeds were recorded. Six types of SSGs were randomly implemented: without pitch orientation-delimitation and with a limit of three ball-contacts per player (3TOU), with no limit of ball-contacts (MAN), with a greater number of players as internal-offensive wildcard players (2WI) or external-offensive wildcard players (4WE); and with pitch orientation-delimitation and crossing the rival goal-line while dribbling the ball without goalkeepers (INV) or using official goalkeepers (GKP). The physical demands of SSGs were compared with the average of two soccer-7 match plays. During soccer-7 match plays a lower %DAC and %DEA (p < 0.05) were observed compared to 2WI, 4WE, INV and GKP, and to INV and GKP, respectively. The V_max and %HI were greater (p < 0.05) in soccer-7 match plays compared to all SSGs. In conclusion, the demands imposed on U12 players during different formats of SSGs differ from the soccer-7 match play demands, presenting a low stimulation of the actions performed at high-speed and an adequate simulation of acceleration-deceleration actions.

Distance at different speeds during soccer-7 match plays and small-sided games. Note: %V1 = percentage of total distance performed at 0-0.4 km/h; %V2 = percentage of total distance performed at 0.5-3.0 km/h; %V3 = percentage of total distance performed at 3.1-8.0 km/h; %V4 = percentage of total distance performed at 8.1-13.0 km/h; %V5 = percentage of total distance performed at 13.1-18.0 km/h; %V6 = percentage of total distance performed at ≥18.1 km/h; OM = soccer-7 match plays; 2WI = small-sided game with two internal wildcards; 3TOU = small-sided game with three touches to the ball; 4WE = small-sided game with four external wildcards; INV = small-sided game with invasion objective; GKP = small-sided game with goalkeepers; MAN = small-sided game with maintenance objective *Significant differences (p < 0.05) compared with OM.
