For years soccer training programs were not specific, and improve technical and analytical exercises were used physical and athletic. The objective of the study was to assess the effects of a training program with small-sided games, over the technique and the physical condition in young footballers. Thirty-six players (12,69±0,48 years old; 39,77±6,20 kg; 146,31±6,36 cm) developed fifteen sessions based on reduced football games (2 vs 2, 4 vs 4 and 8 vs 8). These activities lasted 40 minutes of the session and were performed 2 times a week. The footballer was evaluated twice (pre-test and post-test) through 8 field test: run with the ball, run with the ball and turn, dribbling, header, shot on goal, aerobic resistance, horizontal jump and agility. The statistical analysis by Student's t test reflected significant improvements in driving and dribbling (p≤0,01). Respect to physical variables there were significant improvements in agility and resistance (p≤0,05). The small-sided games are an effective stimulus to improve the execution of certain technical gestures and elements of the physical condition in young players. Use small-sided game can make your time and increase the specificity of the intervention.
