Small-sided games (SSG) have become a popular training method for invasion sports because they have the potential to develop multiple fitness components together with sport-specific skills and tactics. Two studies have specifically examined the value of SSG in improvingCODS and agility performance. One of these compared six weeks of training with either CODSdrills or soccer SSG in untrained men and women. The CODS training was effective(5.9%) for improving performance on the CODS T-test, whereas the SSG had little effect(2.1%, p>0.05). Another recent study on elite junior Australian football players also compared codes training with SSG designed to overload agility skills. However, this study also assessed players on both a CODS test (“Planned Australian Football League agility test”) and a video-based agility test, which was previously validated for Australian football. After 11sessions of training over a seven-week period, the CODS group experienced no significant changes (p>0.05) in either CODS or agility. The SSG group also achieved a trivial change in CODS(p>0.05), but agility performance improved by approximately 4% (P=0.008). This gain was accompanied by a 31% improvement (p0.05) in movement time. Therefore, these results indicate that SSG designed to encourage agility skills may provide a powerful agility training stimulus due to improvements in decision-making speed.
