Effects of manipulating player numbers on technical and physical performances participating in an Australian football small-sided game.

In Australian Football (AF), small-sided games (SSGs) are used extensively to replicate particular technical, tactical or physiological responses. Whilst research on SSGs has been extensive in soccer, in AF it has been limited to agility demands and exploring the effect of field dimensions on technical skill (i.e., handballing) and physical responses of senior athletes. Therefore, this study investigated the effect of four different SSG player number conditions (5v5, 5v6, 6v6, 7v7) on the technical (e.g., kicking) and physical (i.e., odometer, m-min, max velocity and percentage of high intensity running) performance outcomes in 22 sub-elite youth AF players. Particular constraints were applied to the SSG to ensure the focus was on kicking (i.e., after each handball a kick must be performed). The results of this study demonstrate when more technical events are required under more pressured situations (i.e., physical and time) the 5v6 condition appears to be most appropriate. However, when the focus is on kicking to a contested possession (i.e., kicking to leading or covered players) balanced player numbers (e.g., 6v6) would appear optimal. Alternatively, when the SSG focus is on increasing physiological demands (i.e., m.min) lower player density conditions (i.e., 5v5) appear more suitable.
