Abstract

Small-sided games are commonly used by soccer practitioners to condition players. This form of exercise can result in fatigue, potentially exposing the muscle to injury risk. The purpose of this study was to determine the effects of small sided game (SSG) variations on hamstring torque in semi-professional soccer players. In a counter-balanced cross-over design, 10 male semi-professional soccer players took part in both small relative area (3 vs. 3; 300 m2) and large relative area (4 vs. 4; 1000m2) SSGs. The games comprised 6 x 4 min bouts, with 90 s recovery. Both movement and heart rate (HR) responses were monitored by Global Positioning Systems (GPS) and hamstring isometric torque was measured pre- and post-training using a NordBord®. There were differences (P < 0.05) between the small and large relative area games for peak hamstring force decrement (5.78 N and -13.62 N, respectively) and mean hamstring force decrement at 90° (11.11 N and - 4.78 N, respectively). The number of accelerations were related to (r = 0.46, P = 0.039) reduced hamstring peak torque at 90°. In conclusion, larger relative area SSGs elicited the greatest internal and external loads, resulting in decrements in hamstring force. The number of accelerations performed in the session increases the likelihood of hamstring fatigue and can be controlled with the relative pitch area.
