Futebol

Pessoal, como todos sabemos, o CEV mantém um acordo com o centro de documentação da Universidade de Leipzig. Oito Administradores de comunidades estão cadastrados para receber a DSI (Disseminação Seletiva de Informação) sobre temas específicos. Eles peneiram e repassam pras comunidades, ou pro coordenador do CEV. Abaixo vai um exemplo dos resumos que o Álvaro acaba de receber sobre futebol. Gostaria de conversar sobre dois pontos. 1) Artigos na biblioteca 2) Busca de textos completos em estrangeiro mesmo.

1. De vez em quando encontramos almas caridosas e poliglotas que ingressam no programa piedoso do CEV chamado "Adote um Resumo". Daí colocamos o resumo em português na biblioteca do CEV. A primeira idéia, pois, é: cada professor ou pesquisador que tenha algum artigo importante e de interesse para divulgar para os seus estudantes, e para a humanidade em geral, adentra o mosteiro do programa e, certamente, coleciona indulgências, ou, o que é muito mais caro para os dacademia: VISIBILIDADE, já que os resumos registram a autoria do tradutor.

2. Conseguir os artigos inteiros. Reconheço todo o esforço dos pesquisadores (que geralmente recebem subsídios públicos para os trabalhos). Mas, pagar 30 doletas pela cópia de um artigo chega a ser um escárnio. Temos utilizado a solução, digamos, da Rua 25 de março. Alguém de universidade que tem acesso aos periódicos CAPES comete uma cópia escaneada e manda.  Claro, algum dia os cevnautas terão acesso ao PORTAL CAPES. Entretanto, se pingar algum apoio ano que vem podemos remunerar nossos amigos clandestinos pelo trabalho robinwoodiano das cóopias.

Escrevi muito. Vão aí os resumos:

Ali, A. & Williams, C. (2009). Carbohydrate ingestion and soccer skill performance during prolonged intermittent exercise (Kohlenhydrataufnahme und die fußballerische Leistung bei langer Intervallbelastung). J. Sports Sci., 27 (14), 1499-1508. Zugriff am 21.12.2009 unter http://www.informaworld.com/smpp/content~db=all~content=a917441634
The aim of this study was to investigate the effect of ingesting a carbohydrate-electrolyte solution, during the 90-min Loughborough Intermittent Shuttle Test, on soccer skill performance. Seventeen male soccer players ingested either a 6.4 % carbohydrate-electrolyte solution or placebo solution equivalent to 8 ml/kg body mass before exercise and 3 ml/kg body mass after every 15 min of exercise, in a double-blind randomized cross-over design, with the trials separated by 7 days. The evening before the main trial, the participants performed glycogen-reducing exercise on a cycle ergometer (80 min at 70% VO2max) and were then fed a low-carbohydrate meal. After a 12-h overnight fast, they performed The Loughborough Soccer Passing Test before and after every 15 min of exercise. Analysis of the combined skill test data showed a significant time effect (P = 0.001) with differences between 0-45 and 75-90 min (P < 0.05). There was a 3 % reduction in skill performance from before to after exercise in the carbohydrate-electrolyte trial, whereas in the placebo trial the decrease was 14% (P = 0.07). In conclusion, skill performance during the simulated soccer activity appeared to deteriorate in the last 15-30 min of exercise. However, providing 52 g/h carbohydrate during exercise showed a tendency to better maintain soccer skill performance than a taste-matched placebo. (Mikrofiche-Nummer: 18622)

Toering, T. T., Elferink-Gemser, M. T., Jordet, G. & Visscher, C. (2009). Self-regulation and performance level of elite and non-elite youth soccer players (Selbstregulierung und Leistungsniveau bei Jugendfußballern der Elite und der Nicht-Elite). J. Sports Sci., 27 (14), 1509-1517. Zugriff am 21.12.2009 unter http://www.informaworld.com/smpp/content~db=all~content=a917442187
In learning and development, self-regulation can be described as the extent to which individuals are metacognitively, motivationally, and behaviourally proactive participants in their learning process (Zimmerman, 1989, 2006). We examined the relationship between self-regulation and performance level in elite (n = 159) and non-elite (n = 285) youth soccer players aged 11-17 years (mean 14.5 years, s = 1.4). The players completed a questionnaire that assessed planning, self-monitoring, evaluation, reflection, effort, and self-efficacy. A logistic regression analysis was performed (controlling for age) to determine which self-regulatory aspects were associated with players’ performance level (elite vs. non-elite). High scores on reflection and effort were associated with a higher level of performance. Findings suggest that elite players may be more aware of their strong and weak points as well as better able to translate this awareness into action. In addition, elite players appear to be more willing to invest effort into practice and competition. It is suggested that these better developed self-regulatory skills may translate into a more effective learning environment and ultimately result in an increased capacity for performance in elite players relative to their non-elite peers.

Mujika, I., Spencer, M., Santisteban, J., Goiriena, J. J. & Bishop, D. (2009). Age-related differences in repeated-sprint ability in highly trained youth football players (Altersbezogene Unterschiede der wiederholten Sprintfähigkeit bei hochtrainierten jugendlichen Fußballspielern). J. Sports Sci., 27 (14), 1581-1590. Zugriff am 21.12.2009 unter http://www.informaworld.com/smpp/content~db=all~content=a917446746
In this study, we investigated the age-related differences in repeated-sprint ability and blood lactate responses in 134 youth football players. Players from the development programme of a professional club were grouped according to their respective under-age team (U-11 to U-18). Following familiarization, the participants performed a repeated-sprint ability test [6 30-m sprints 30 s apart, with active recovery (2.0-2.2 m • s-1) between sprints]. The test variables were total time, percent sprint decrement, and post-test peak lactate concentration. Total time improved from the U-11 to U-15 age groups (range 33.15 ± 1.84 vs. 27.25 ± 0.82 s), whereas no further significant improvements were evident from U-15 to U-18. No significant differences in percent sprint decrement were reported among groups (range 4.0 ± 1.0% to 5.5 ± 2.1%). Post-test peak lactate increased from one age group to the next (range 7.3 ± 1.8 to 12.6 ± 1.6 mmol/l), but remained constant when adjusted for age-related difference in body mass. Peak lactate concentration was moderately correlated with sprint time (r = 0.70, P > 0.001). Our results suggest that performance in repeated-sprint ability improves during maturation of highly trained youth football players, although a plateau occurs from 15 years of age. In contrast to expectations based on previous suggestions, percent sprint decrement during repeated sprints did not deteriorate with age. (Mikrofiche-Nummer: 18629)
