Offensive sequences in youth soccer: experience and small-sided games effects
On the other hand, the use of small-sided games (SSGs) in these processes is a current circumstance that has triggered the attention of some researchers. Previous studies have pointed out that SSGs are an efficient strategy to increase players’ specific practice time, eliciting simultaneously physical and technical aspects within a major tactical involvement (e.g., Duarte et al., 2009; Hill-Haas et al., 2009; Katis and Kellis, 2009). Thus, the acquisition of technical and tactical skills can be thought according to a net of interacting constraints such as the individual, task and the environmental constraints (Handford et al., 1997; Williams and Hodges, 2005). In the scope of a constraints-led approach, the game format presented to players constraints them to solve specific game problems with implications on the individual and collective actions that are performed (Handford et al., 1997). Nevertheless, it is not clear how players with different levels of experience respond to similar practice tasks.
