Effects of pacing, status and unbalance in time motion variables, heart rate and tactical behaviour when playing 5-a-side football small-sided games

The presence of the head coach during a small-sided game: effects on players´ internal load and technical performance. [La presencia del entrenador durante un juego reducido: efectos sobre la carga interna y rendimiento técnico].

“…Changes in pitch dimensions (Casamichana et al, 2010), introduction of goals (Castellano et al, 2013;Köklü et al, 2015), variations in the number of players ), constraints in ball touches per individual possession (Dellal, Lago-Penas, Wong, & Chamari, 2011), or the introduction of manmarking (Ngo, Man-Chung, Smith, Carling, Gar-Sun, & Wong, 2012) all influence the intensity of the SSG. In addition, in team sports where the coach can communicate with the athletes, it does so using keywords to conduct efforts to the maximum possible intensity, this is valid for variables such as the information provided by the head coach before (Sampaio, Lago, Gonçalves, Maçãs, & Leite, 2013) and during the task (Rampinini et al, 2007) seems to influence the intensity during SSG positively. However, to our best knowledge, this is the first study to examine the potential influence of the presence / absence of the head coach on the internal load and frequency of technical/tactical aspects.…”

“…There is little information regarding game pace while performing SSG. Sampaio et al (2013) studied the effect of informing players before the start of game pace (slow pace, normal pace and fast pace). No differences were reported between normal pace and fast pace, suggesting that players not informed about the pace of play can lead to a very small quantity of slow pacing game.…”

“…Therefore, knowing this fact, we must be aware that the PHC is not favoring the success of this important point in the overall development of the sport technical action. Although the lack of confirmation strategic behaviors of the teams to explain their organization and dynamics during these practices (Sampaio et al, 2013), it could be accepted that the head coach's presence has significantly influenced the intensity of defensive and offensive actions, which has led the team in possession of the ball decreases their success and increased error in technical actions.…”

“…Knowledge of the locomotors demands of players during the task (e.g., time-motion analyses) and the tactical/strategic behavior of the players could also provide interesting information, for example dynamics of emergent behavior (Sampaio et al, 2013) with the intention of determining the response of the players in different situations from a global perspective. In conclusion, the present data clearly demonstrate that the presence or absence of the head coach during the task, significantly influenced the intensity of the game and technical-tactical actions.…”

Efeitos Do Treinamento Em Jogos Reduzidos Com Inferioridade Numérica No Futebol

“…As variáveis cardiorrespiratórias são mais responsivas a exercícios de elevada intensidade, na condição de inferioridade numérica, observada em jogos reduzidos 10 . A frequência cardíaca é uma variável utilizada como indicador da intensidade do exercício, assim como a percepção subjetiva de esforço 11,12 . Tem sido sugerido que o tempo e a intensidade da atividade podem afetar algumas variáveis psicológicas como a atenção concentrada 13 .…”
