Os recentes desenvolvimentos tecnológicos permitem capturar as posições dos jogadores de futebol durante a sua prática, tanto em treino como em jogo, com um elevado grau de precisão e baseado em procedimentos simples. Esta informação tem proporcionado o acesso a conhecimento relevante para a análise da performance, particularmente relacionado com a performance física. Pouca atenção tem sido dada ao processo de ...
O equilíbrio muscular é, em qualquer actividade desportiva, de vital importância para a manutenção da funcionalidade das articulações. Na natação pura desportiva, devido ao caráter cíclico da utilização dos músculos dos ombros, existe uma maior propensão para lesões nesta articulação, essencialmente motivadas pelos desequilíbrios musculares entre rotadores internos (RI) e rotadores externos (RE) [1]. No caso da...
A network of patterned interactions between players characterises team ball sports. Thus, interpersonal coordination patterns are an important topic in the study of performance in such sports. A very useful method has been the study of inter-individual interactions captured by a single camera filming an extended performance area. The appropriate collection of positional data allows investigating the pattern for...
Os jogos reduzidos são frequentemente usados tanto no treino como no ensino de futebol, e têm sido bastante estudados por diferentes abordagens. No entanto, e apesar de ser um aspecto importante dos jogos reduzidos, poucos estudos se têm focado nas implicações tácticas deste tipo de exercícios. O objectivo deste estudo é identificar de que forma o comportamento táctico colectivo varia entre equipas de diferente...
The purpose of this study was to analyze the informational constraints that influence the dynamics of 1v1 situations in football. Specifically, we analyzed the contribution of interpersonal distance and relative velocity to explain phase transitions that occurred between stable and unstable coordinative states in 1v1 in football. Participants were six, U13 level football players (Mean age: 11.8±0.4 yrs), who pe...
Recent findings demonstrate that Futsal is a multiple-sprint sport in which high-intensity exercise constitutes a greater proportion of match time than all other team sports (Barbero-Alvarez et al., 2008), but the research of training intensity is a unknown way. Sport specific drills with variations are constantly used in Futsal practices, however the knowledge about how these variations influence drill intensi...
Research on expert performance field revealed a strong trend in the association of the birth dates of elite athletes to the first trimesters of the year (Wattie et al. 2008). The aim of this study was to analyze the birth date distribution of all top elite athletes who participated in Olympic Games at Beijing 2008. Athletes (n = 18.132) were divided according to gender, continent and sports. The birth dates of ...
In the design of training programs, it is common for coaches to modify task constraints to conduct the drill intensity at the targeted level. Sport specific drills with variations are constantly used in Futsal practices, however the knowledge about how these variations influence drill intensity and technical demands is very scarce. The purpose of this study was to measure the physiological and technical effects...
Gerontological research has shown that there is a marked decline in health with age and an associated demand for expensive medical services (Shepard, 1993). Some previous studies underline sedentary lifestyle as main responsible factor for hypokinetic diseases and reduction in quality of life (Rejeski et al, 1996). By contrast, among the elderly evidences show a positive relationship between regular physical ac...
Small-sided soccer games allow increasing players specific practice time eliciting simultaneously phy- sical and technical aspects within a major tactical involvement. Youth players’ performance in ‘‘three- a-side’’ drills are used very often without knowing their real impact. Thus, the aim of the current study was to identify heart rate and technical responses to variation in pitch dimension (30620 m; 20615 m)...
