Having established that agility and CODS are specific skills, the critical question that follows is which of these skills is more important for performance? This issue can be addressed by comparing higher- and lower-standard groups of athletes. If a superior-skilled group is better on a particular test, the quality assessed by that test can be said to be important for performance in the sport. Conversely, if a higher-level group is not better on a test, the quality assessed by that test would appear to have little relevance to superior sports performance. Using such a research-design, several studies have shown the higher-skilled group to be superior (p0.05) in a CODS test in Australian football and rugby league. These results clearly indicate that agility is more related to performance in these invasion sports than CODS tests, and provides evidence for the importance of the perceptual and decision-making element of agility.
