The increase of research in this topic is coincident with the increase of popularity obtained by specific soccer conditioning, which involves training players to deal with soccer match situations. Given the limited time available for fitness training in soccer, the effectiveness of small-sided games as a conditioning stimulus needs to be optimized to allow players to compete at the highest level. Available studies indicate that physiological responses (e.g. heart rate, blood lactate concentration and rating of perceived exertion), tactical and technical skill requirements can be modified during small-sided games by altering factors such as the number of players, the size of the pitch, the rules of the game, and coach encouragement. However, because of the lack...

Additionally, numerous studies have suggested that PA lias, or may potentially have, positive impacts on health and longevity (Adamu, Sani & Abdu, 2006; Aires, Silva P., Silva G., Santos, Ribeiro, & Mota, 2010; Berlin & Colditz, 1990; Keiler, Manning, Newhouse, Sloss, & Wasscrman. 1989; Ortega, Ruiz, Castillo & Sjostrom 2008; Powell, Thompson. Caspersen & Kendrick, 1987; Ruiz, Castro-Pinero, Artero, Ortega, Sjostrom Castillo, 2009). Overweight and obesity in adolescence have dramatically increased over the past few years in developed countries (Jolliffe, 2004; Lobstein & Frelut, 2003; Wang, Monteiro & Popkin, 2002).

Childhood obesity is associated with increased cardiovascular mortality and morbility in adult life. Evidence suggests that non-physically active children or adolescents are more likely to become non-physically active adults, and encouraging the development of physical activity (PA) habits in children could help to establish patterns that remain into adulthood (Watts, Jones, Davis, & Green, 2005).PA results in increased capacity and physical fitness (PF), which may lead to many health benefits. Numerous studies have suggested that PF and/or habitual PA have, or potentially have, positive impacts on health and longevity (Aires, Silva, Silva, Santos, Ribeiro & Mota, 2010; Marta, Marinho & Marques, 2012; Ortega, Ruiz, Castillo & Sjostrom, 2008; Ruiz, Castro-Pinero, Artero, Ortega, Sjostrom & Castillo, 2009). In fact, two important behaviours linked with lifestyles are strongly ...

Methods: Data were gathered using GPS during 5-a-side games performed by under-19 elite soccer players. Results: The results revealed significant differences between clusters in almost all the variables, assuring that the regularity of the distance to centroid accurately discriminated the short from the long sequences of play. Also, the analyses revealed moderate significant interaction between Type of Relation (intra-team vs. inter-team) Sequences of Play (short vs. long) independently of the variable taken as criterion to divide the clusters. Conclusions: Regularity of intra- and inter-team interpersonal coordination is able to discriminate short and long sequences of play during SSG. Generally, short sequences of play displayed higher irregularity than the longer sequences. In the long sequence, inter-team interactions were more irregular than the interactions with teammates, while data showed an opposed trend to the short sequences of play. These findings can be useful for coaching instructional purposes, especially in the design of practice tasks setting the appropriate constraints to promote either short or long offensive sequences of play according to the team characteristics.
