Comparison of the movement patterns between small- and large-sided game training and competition in professional soccer players

BACKGROUND: The purpose of this investigation was to compare the movement patterns of professional soccer players during a small-sided game (SSG), a large-sided game (LSG), and a competitive friendly match (FM). METHODS: Fourteen professional players participated in three training routines with a similar relative pitch area per player. The SSG and LSG consisted of 8 repetitions of 4-min game play, interspersed by 2 minutes of active recovery, and their data were compared to the first 32 minutes of a FM. All movement patterns from walking to sprint running were recorded using 10-Hz GPS devices while player perception of exertion was recorded via visual analogue scale, post-trial. RESULTS: Total running distance (3852 +/- 405 vs. 3359 +/- 429 and 3088 +/- 414 m), running distance at 5-6.9 m/s (222 +/- 98 vs. 75 +/- 53 and 49 +/- 35 in) and maximal running speed (7.0 +/- 0.7 vs. 6.1 +/- 0.4 and 6.0 +/- 0.7 m/s) were significantly greater during FM than for SSG and LSG. However, the number of accelerations (462 +/- 16 vs. 458 +/- 12 vs. 422 +/- 15) and decelerations (733 +/- 31 vs. 692 +/- 24 vs. 609 +/- 27), and the rating of perceived exertion (8 +/- 1 vs. 7 +/- 1 vs. 5 +/- 1) were significantly greater during SSG compared to LSG and FM. CONCLUSIONS: Although smaller game-based training routines do not replicate exactly the movement patterns of a competitive match, they can increase the execution of short-term and high-intensity movements for specialized training in professional soccer players.
