Aim: The aim of the present study was to examine the outcome of repetitive-part training and dual-task training in the acquisition of dribbling technique and decision making in prepubescent novice soccer players. Method: Twenty four preschool pupils, with an age of 6.2 ± 0.4 years (mean ± SD) and with no previous experience of partaking in any organized team or ball sport participated in the study. The participants were tested (pre test) for initial performance level of dribbling technique and decision making and were then divided into two balanced experimental groups. The repetitive-part group underwent four weeks of part-task training (isolated dribbling-technique training) which were followed by four weeks of dual-task training (simultaneous training of dribbling technique and decision making). The dual-task group underwent eight weeks of dual-task training. The outcome in acquisition of dribbling technique and decision making was examined after four (mid test) and eight (post test) weeks of training. Both training regimes were followed by four weeks of non-training and thereafter a test (retention test) of the retention effects was carried out. Effect sizes (d) of the acquisition within each group and of the difference in performance and acquisition between the two groups were evaluated based on Cohen's effect size criteria (|d| > 0.2, small effect; |d| > 0.5, moderate effect; |d| > 0.8, large effect). Results: Between the pre and mid test, both groups showed large improvements in dribbling technique. The corresponding improvement was small in the repetitive-part group and moderate in the dual-task group between the mid and post test. There were large differences between the groups' decision-making performances at the mid, post, and retention test where the dual-task group was superior to the repetitive-part group. The dual task group showed large improvements of decision making between the pre and mid test. Between the mid and post test, the corresponding effect was large within the repetitive-part group and moderate in the dual-task group. The improvement of the dual-task group's decision making between the pre and mid test was greater than the corresponding improvement showed by the repetitive-part group, between the mid and post test. This difference produced a moderate effect size. Conclusions: These findings challenge conventional repetitive-part training regimes and, with references to previous research, emphasize the importance of dual-task training for skill acquisition in prepubescent novice soccer players.

In order to do so, citizens, communities and the city are understood as texts (in the semiotic comprehension of the term) as well as subjects involved in the interactive dynamics of the narrative significant that this type of soccer practice constitutes, bringing meaning in itself. It is intended to comprehend the construction of new meanings of this type of sports practice in practical life, which is done by several citizens in São Paulo city, especially in suburbia areas. Taking this type of soccer practice as the object of this study, the following question is proposed: how do subjects and communities of São Paulo city interact, build sense, show and see themselves through this type of soccer practice? Which interactions, senses and visibilities are constituted? The hypothesis is that this practice presents for the subject, the pairs (other subjects and communities) and the city beyond (and within) the floodplain identities and values which move these citizens in the relation with the city. The study is based theoretically on the Discursive Semiotics of A. J. Greimas and followers (with special focus on the works of D.L.P. Barros e J.L. Fiorin), the Sociosemiotics of E. Landowski and the Plastic Semiotic approach of A.C. de Oliveira, based on J-M. Floch. The corpus comprehends a historical research of soccer (and the several types of soccer which were constituted in São Paulo city, including the floodplain soccer practice) and the experience with the object in action and relation from 2010 to 2012, in the following competitions: Kaiser Cup of Amateur Soccer and Peace Cup Dreher, as well as in the Palmeirinha do Paraisópolis floodplain soccer team. The conclusion is that these subjects express, through the floodplain soccer practice, the values that rule their existence, in their life narratives. By re-semanticizing the sport which is Brazilians favorite , these players, supporters and community dwellers interact, feel and constitute a living shared among equals, enjoying the same way of life in the city. The new media destinators capitalized in the floodplain soccer practice in São Paulo city, such as Kaiser and Dreher, produce changes in the dynamics of sense production / O presente trabalho estuda os regimes de interação, sentido e visibilidade que fazem-ser e ver a prática do futebol de várzea na cidade de São Paulo. Para tal, se consideram os cidadãos, as comunidades e a metrópole como textos (na acepção semiótica do termo) e como sujeitos imbricados nas dinâmicas interativas da significante narrativa que é a modalidade varzeana, pela qual se fazem apreender, além da visão, pelo conjunto dos sentidos. Pretende-se compreender as ressemantizações de uma prática esportiva em específica prática de vida, que é o jogar futebol de várzea, efetuado por milhares de paulistanos, especialmente nas periferias. Tomando-se como objeto esta forma do esporte, busca-se responder: como sujeitos e comunidades de São Paulo interagem, fazem sentido, se fazem-ver e são feitos-ver pelo futebol de várzea? E quais as interações, sentidos e visibilidades que se fazem? A hipótese é a de que essa prática presentifica para si mesmo, seus pares (outros sujeitos e comunidades) e a cidade além (e aquém) da várzea identidades e valores que movem esses paulistanos na relação com a metrópole. O estudo adota como referencial teórico a Semiótica Discursiva desenvolvida por A.J. Greimas e seguidores (especialmente as colaborações de D.L.P. de Barros e J.L. Fiorin), a Sociossemiótica de E. Landowski e a abordagem da Semiótica Plástica realizada por A.C. de Oliveira, na esteira de J-M. Floch. O corpus compreende a pesquisa histórica do futebol (e dos diversos futebois que foram feitos-ser em São Paulo, incluindo a modalidade varzeana) e a vivência do objeto, em ato e em relação, nos anos de 2010 a 2012, pelas competições Copa Kaiser de Futebol Amador, Copa da Paz Dreher e ainda pelo time Palmeirinha do Paraisópolis. A conclusão é que tais paulistanos, nas suas narrativas de vida, enunciam pelo futebol de várzea os valores que regem sua existência. Ressemantizando o esporte que é paixão do brasileiro , esses jogadores, torcedores e moradores interagem, sentem e (se) fazem-ver um viver partilhado entre iguais, desfrutando um mesmo modo de vida na capital paulista. Os novos destinadores midiáticos capitalizados do futebol de várzea de São Paulo, como Kaiser e Dreher, fazem-sentir mudanças nas dinâmicas de geração de sentidos
