          Abstract

          Abstract This study aimed to compare technical actions of soccer players from different playing position during small-sided games in which teams were composed of playersfrom the same position (e.g., three defenders). In total, 14 U-14 soccer players (14.43 ± 0.16 years), four defenders, four midfielders and four forwards, as well as 2 non-evaluated goalkeepers, participated in this study. The incidence of technical actions performed by players was analyzed through proportion chi-square test and omega effect sizes, and significance level was set at 5%. Results showed no differences in technical actions performed by players from different playing positions (p>0.05, small effect size). Thus, it is suggested that the 3v3 small-sided game, with teams composed of athletes with the same playing position, is characterized by a more general training stimulus, which can be particularly useful during the first years of deliberate practice.

          Resumo Este estudo objetivou comparar as ações técnicas de jogadores de futebol de diferentes posições em pequenos jogos com equipes compostas por atletas de mesma posição (e.g., três defensores). Participaram do estudo 14 atletas de futebol categoria sub-14 (14,43 ± 0,16 anos) divididos em 4 defensores, 4 meio-campistas e 4 atacantes, além de dois goleiros não avaliados. A incidência das ações técnicas realizadas foi analisada por meio do teste de qui-quadrado de proporções e do tamanho do efeito ômega, mantendo-se nível de significância em 5%. Os resultados apontam para a ausência de diferenças nas ações técnicas realizadas por jogadores de diferentes posições (p>0,05, tamanho do efeito pequeno). Desta forma, sugere-se que o pequeno jogo 3v3, com equipes compostas por atletas de mesma posição, permite um estímulo geral em relação às especificidades do estatuto posicional, apresentando-se particularmente útil em momentos iniciais da formação esportiva.

          Evolution of match performance parameters for various playing positions in the English Premier League.

          This study aimed to investigate position-specific evolution of physical and technical performance parameters in the English Premier League (EPL). Match performance observations (n=14700) were collected using a multiple-camera computerized tracking system across seven seasons (2006-07 to 2012-13). Data were analyzed relative to five playing positions: central defenders (n=3792), full backs (n=3420), central midfielders (n=3200), wide midfielders (n=2136) and attackers (n=2152). High-intensity running distance increased in the final season versus the first season in all playing positions (p<.05, ES: 0.9-1.3) with full backs displaying the greatest increase (∼36% higher in 2012-13). Similar trends were observed for sprint distance with full backs demonstrating the most pronounced increase across the seven seasons (36-63%, p<.001, ES: 0.8-1.3). Central players (central defenders and midfielders) illustrated the most pronounced increases in total passes and pass success rate (p<.05, ES: 0.7-0.9) whilst wide players (full backs and wide midfielders) demonstrated only small-moderate increases in total passes and pass success rate (p<.05, ES: 0.6-0.8). The data demonstrates that evolving tactics in the EPL have impacted on the physical demands of wide players and the technical requirements of central players. These findings could be used for talent identification or position-specific physical and technical training.

            Technical performance and match-to-match variation in elite football teams.

            Recent research suggests that match-to-match variation adds important information to performance descriptors in team sports, as it helps measure how players fine-tune their tactical behaviours and technical actions to the extreme dynamical environments. The current study aims to identify the differences in technical performance of players from strong and weak teams and to explore match-to-match variation of players' technical match performance. Performance data of all the 380 matches of season 2012-2013 in the Spanish First Division Professional Football League were analysed. Twenty-one performance-related match actions and events were chosen as variables in the analyses. Players' technical performance profiles were established by unifying count values of each action or event of each player per match into the same scale. Means of these count values of players from Top3 and Bottom3 teams were compared and plotted into radar charts. Coefficient of variation of each match action or event within a player was calculated to represent his match-to-match variation of technical performance. Differences in the variation of technical performances of players across different match contexts (team and opposition strength, match outcome and match location) were compared. All the comparisons were achieved by the magnitude-based inferences. Results showed that technical performances differed between players of strong and weak teams from different perspectives across different field positions. Furthermore, the variation of the players' technical performance is affected by the match context, with effects from team and opposition strength greater than effects from match location and match outcome.

              Effect of bout duration on exercise intensity and technical performance of small-sided games in soccer.

              To examine whether the increase in bout duration would affect the exercise intensity and technical actions, we manipulated bout duration during a typical small-sided game drill (SSG) in male soccer players. Nineteen players (mean ± SD: age 24 ± 4 years, body mass 74 ± 4 kg, and height 180 ± 5 cm) completed three bouts of a 3-a-side drill at three different bout durations: 2, 4, and 6 minutes. Exercise intensity was quantified using heart rate (HR) and rating of perceived exertion (RPE). A nonsignificant duration × bout interaction was found for HR (p = 0.757). Heart rates of bout 1 were significantly lower than bout 2 (p = 0.004) and bout 3 (p = 0.049). The effect of duration was close to significance for HR (p = 0.057) with 6-minute SSG significantly lower than 4-minute SSG (p = 0.004). Duration × bout interaction did not reach the significance for RPE (p = 0.096). The RPE significantly increased along the bouts (p 0.111). A significant effect of bout was only found for successful passes (p = 0.018). Partially confirming our hypothesis, the increase in bout duration from 2 to 6 minutes resulted in a decrease in intensity only between the 4- and 6-min SSG. However, duration did not influence the technical actions and proficiency. The magnitude of changes in HR (89.5 vs. 87.8 of maximum) is probably not enough to induce different training adaptations. Therefore, coaches can use different bout durations with minimal impact on exercise intensity and without compromising technical proficiency.
