Purpose. The purpose of the study was to identify the reasons why training athletes practise soccer, as well as verify changes in motivation in under-15 and under-17 athletes. Methods. Overall, 100 male training athletes from a 2 nd division soccer club of the Brazilian Men's soccer Championship in the state of Goiás participated in the research. The subjects were divided into 2 categories: under-14 (aged 12-14 years) and under-17 (aged 15-17 years). The mean age equalled 14.3 ± 1.4 years and the experience time was 10 ± 4 months. The instrument for data collection was the Motives for Physical Activity Measure-revised scale. Results. The results showed that the main reason for practising soccer was fun, followed by competence, fitness, social aspects, and appearance, successively [F(3,195,316,349) = 60.036; p < 0.05]. However, when analysing the category of 12-14 years, no difference was observed between the fun and competence dimensions, between competence and fitness, or between fitness and social aspects. The comparison between the categories proved that there were differences in appearance and social aspects dimensions, and that these aspects motivated more the athletes aged 15-17 years. Conclusions. Consequently, the intrinsic motivation, specifically the reasons related to fun and competence, were the factors considered most important for soccer practice among young training athletes aged 12-17 years.

The aim was to identify the predictive factors of the attack efficacy of the Brazilian women’s League Champion team according to the level of performance of the opposing team.The sample was composed of the observation of 1137 attacks in 21 games of the 2015-2016 Brazilian women’s Volleyball League champion team. The results were significant to identify the predictive factors of the attack efficacy against high (.2=110.562; .<0.00001), intermediate (.2=64.134; .<0.00001) and low (.2=62.137; .<0.00001) performance opponents. Thus, it is concluded that when playing against high- performance teams, powerful attack for position 6 and second attack tempo increase the chances of attack point; powerful attacks for position 1 and 5 reduce the chances of game continuation; and powerful attack for position 6 increases the chances of blocking. In addition, in games against intermediate-performance teams, reception that allows organized attack without all attack options reduces the chances of attack point and game continuation, while the reception effect did not seem to be a predictive factor of the attack efficacy in games against high- and low-performance opponents and, finally, in games against low-performance teams, powerful attack for position 1 reduces the chances of game continuation and attack blocking.

The present research objective was to analyze the offensive phase from Complex I in high-level male volleyball teams in a macro- and micro-level view, through the inter e intra-team variability analysis of eight best teams of the 2018 Men’s Volleyball World Championship over the social network analysis and eigenvector centrality. The sample consisted of 22 matches and 2,743 offensive actions, resulting in 8 sub-networks with 368 nodes and 6221 edges. The results showed from macro view the variables that presented highest centrality values were Attack Zone 4 (range 0.56–0.90), Attack Tempo 2 (0.65–0.87), Power Attack (0.62–0.94), No Touch Block (0.61–1), Attack Effect Continuity (0.59–0.94), and Middle Blocker Centralized (0.60–0.95). In a micro view, Reception Effect, Play Position, Reception Zone, and Block Composition showed high variability in each sub-network. The intra- and inter-team variability presented the importance of to respect each team idiosyncrasies and to consider the different approaches to the game and success.

A presente nota técnica problematiza as questões relativas às diretrizes curriculares nacionais referentes à área da Educação Física, sobretudo no que diz respeito à origem, aos documentos históricos relacionados à divisão da formação, e as evidências trazidas pelo projeto de Minuta do CNE. Além disso, apresenta elementos teórico-conceituais e evidências históricas acerca da Educação Física no Brasil. Após percorrer a gênese da construção da área, enfatiza-se o atual momento de incerteza sobre a formação, conclui-se que o caminho para a Educação Física passa por um entendimento entre as correntes ideológicas da área, e o alinhamento entre a formação e o mercado.
