Time-motion analysis in women’s team handball: importance of aerobic performance

Women’s handball is a sport, which has seen an accelerated development over the last decade. Data on movement patterns in combination with physiological demands are nearly nonexistent in the literature. The aim of this study was twofold: first, to analyze the horizontal movement pattern, including the sprint acceleration profiles, of individual female elite handball players and the corresponding heart rates (HRs) during a match and secondly to determine underlying correlations with individual aerobic performance. Players from one German First League team (n = 11) and the Norwegian National Team (n = 14) were studied during one match using the Sagit system for movement analysis and Polar HR monitoring for analysis of physiological demands. Mean HR during the match was 86 % of maximum HR (HRmax). With the exception of the goalkeepers (GKs, 78 % of HRmax), no position-specific differences could be detected. Total distance covered during the match was 4614 m (2066 m in GKs and 5251 m in field players (FPs)). Total distance consisted of 9.2 % sprinting, 26.7 % fast running, 28.8 % slow running, and 35.5 % walking. Mean velocity varied between 1.9 km/h (0.52 m/s) (GKs) and 4.2 km/h (1.17 m/s) (FPs, no position effect). Field players with a higher level of maximum oxygen uptake (V̇O2max) executed run activities with a higher velocity but comparable percentage of HRmax as compared to players with lower aerobic performance, independent of FP position. Acceleration profile depended on aerobic performance and the field player’s position. In conclusion, a high V̇O2max appears to be important in top-level international women’s handball. Sprint and endurance training should be conducted according to the specific demands of the player’s position.

Estudio sobre la utilización de los gestos técnicos en pelota valenciana en jugadores profesionales

Debido a la escasez de estudios de análisis en pelota valenciana, hemos centrado este estudio en este deporte. El objetivo de estudio ha sido analizar y cuantificar los tipos de golpeos, y comparar los mismos entre las posiciones de juego de resto y medio. Para ello se han llevado a cabo el análisis de 6 partidas de la XIX Liga Profesional de «escala i corda» 2009-2010, y en concreto de 12 jugadores, utilizando el software de análisis Sports Code v.8.5.2. Los resultados nos indican diferencias significativas (p<0.05) entre los golpeos efectuados por el jugador resto y el jugador medio en el rebote y rebote a golpe de mano derecha e izquierda y caída de escalera de mano derecha; siendo estos prácticamente realizados únicamente por los jugadores de la posición resto. Al mismo tiempo encontramos datos que nos evidencian por otra banda golpeos utilizados principalmente por jugadores medios, estas han sido el golpeo de volea, el bote de brazo, el calbote, la palma, y el manró todos ellos de mano derecha. Como conclusión del estudio, hemos obtenido que dependiendo de la posición de juego los jugadores utilizan unos tipos de golpeo u otros. Por tanto, afirmamos, que el análisis del alto rendimiento en escala i corda desde los avances de las tecnologías, nos aporta una valiosa información para establecer patrones de entrenamiento específicos.

El objetivo de este estudio es analizar la frecuencia cardiaca (FC) y la percepción subjetiva del esfuerzo (RPE) en los entrenamientos de fútbol sala en jugadoras (25.42±4.42 años, 166.57±7.14 cm, 56.50±4.95 kg y 22.23±0.97 IMC) de un equipo de primera división de la liga nacional española. Se registraron, mediante monitores de ritmo cardiaco y la escala de Foster, ocho sesiones de entrenamiento de tipo técnico-táctico, físico y partidos modificados, distribuidas durante la mitad de la temporada. Los resultados de la FC máxima y media obtenida son 174.03±4.15 y 128.29±0.81 ppm en sesiones técnico-tácticas, 179.75±2.05 y 132±2.12 ppm en sesiones físicas, 180.99±1.06 y 133.63±5.52 ppm en partidos modificados, respectivamente. Habiendo diferencias significativas en los resultados de la FC máxima entre las sesiones técnico-tácticas y los partidos modificados (p=0.03) y entre la sesiones físicas y las técnico-tácticas (p=0.04). En cuanto a los resultados de la carga de entrenamiento y la RPE en las sesiones técnico-tácticas son 381.22±16.42 y 6.21±0.12 rpe, en las sesiones físicas 533.25±5.59 y 7.90±0.0 rpe, y en los partidos modificados 531.18±4.21 y 7.97±0.22 rpe, respectivamente. Encontrando diferencias significativas entre los resultados de la RPE y la magnitud de la carga de entrenamiento de las sesiones técnico-tácticas y los partidos modificados (p=0.00) y entre la sesiones físicas y las técnico-tácticas (p=0.00). Estos resultados muestran que la sesión de partido modificado obtiene unos valores de frecuencia cardiaca y de percepción subjetiva del esfuerzo mayor que las sesiones técnico-tácticas y las de trabajo físico.

O ensino superior das artes visuais na União Europeia à luz do Processo de Bolonha

No presente artigo procurar-se-á, depois de uma breve abordagem sobre a concretização do Processo de Bolonha, nos países da união europeia, compreender em que fase se encontra a adequação dos cursos de Artes Visuais e em que medida têm sido acolhidas as orientações emanadas das diferentes conferências de ministros que tutelam o ensino superior, quanto à estrutura de graus, à duração dos ciclos, à implementação do sistema de garantia da qualidade, entre outros aspectos. Advirta-se, contudo, que para efeitos da presente caracterização apenas se consideraram as instituições de ensino superior com sítios disponíveis na internet, tendo sido efectuada a recolha de dados durante o ano de 2008 e o primeiro trimestre de 2009. O levantamento das instituições foi feito junto das associações internacionais, consideradas interlocutoras credíveis como a ELIA (The European League of Institutes of ARTS) e a Cumulus Association Of Universities and Colleges of Art, Design and Media. Em Portugal, esse levantamento foi feito junto da Direcção Geral do Ensino Superior e em Espanha junto da ANECA (Agencia Nacional de Evaluacion de la Calidad Y Acreditacion).

Place but not Date of Birth Influences the Development and Emergence of Athletic Talent in American Football

The purpose of this study was to examine the birthplace and relative age effects in National Football League (NFL) players. The place and date of birth of NFL players in the United States were analyzed with Monte Carlo simulations to determine if either factor was predictive of the probability of reaching the elite level in this sport. Consistent with previous findings on professional North American athletes in baseball, ice hockey, basketball, and golf, players born in cities with populations of less than 500,000 were significantly over-represented in the NFL, whereas players born in cities with populations over 500,000 were significantly under-represented. Unlike many other sports, no relative age effects were found for the NFL. Small cities, in particular, appeared to possess characteristics that facilitate the development and/or emergence of athletic talent in American football. Possible psychosocial factors mediating the birthplace effect are discussed as are implications for the development of sporting expertise.

Birthplace Effects on the Development of Female Athletic Talent

This study examined the extent to which an athlete's place of birth can influence the likelihood of playing professional sport. Information regarding the birthplace of all American female athletes in the Ladies Professional Golf Association and Women's United Soccer Association was gathered from official league websites. Monte Carlo simulations were used to determine if the birthplace of these professional athletes differed in any systematic way from official census population distributions. Odds-ratios were determined for cities within specific population ranges to ascertain if the likelihood of playing professional sport was influenced in any systematic way by city size. The analyses revealed that female professional soccer players born in cities of less than 1,000,000 were over-represented, as were female professional golfers born in cities of less than 250,000. Results are consistent with those of male professional athletes in suggesting that areas of lower population provide conditions more conducive to the development of expertise than do larger city environments.

When “Where” is More Important Than “When”: Birthplace and Birthdate Effects On The Achievement Of Sporting Expertise

In this study, we assessed whether contextual factors related to where or when an athlete is born influence their likelihood of playing professional sport. The birthplace and birth month of all American players in the National Hockey League, National Basketball Association, Major League Baseball, and Professional Golfer's Association, and all Canadian players in the National Hockey League were collected from official websites. Monte Carlo simulations were used to verify if the birthplace of these professional athletes deviated in any systematic way from the official census population distribution, and chi-square analyses were conducted to determine whether the players' birth months were evenly distributed throughout the year. Results showed a birthplace bias towards smaller cities, with professional athletes being over-represented in cities of less than 500,000 and under-represented in cities of 500,000 and over. A birth month/relative age effect (in the form of a distinct bias towards elite athletes being relatively older than their peers) was found for hockey and baseball but not for basketball and golf. Comparative analyses suggested that contextual factors associated with place of birth contribute more influentially to the achievement of an elite level of sport performance than does relative age and that these factors are essentially independent in their influences on expertise development.

The Contribution of Structured Activity and Deliberate Play to the Development of Expert Perceptual and Decision-Making Skill

The developmental histories of 32 players in the Australian Football League (AFL), independently classified as either expert or less skilled in their perceptual and decision- making skills, were collected through a structured interview process and their year-on-year involvement in structured and deliberate play activities retrospectively determined. Despite being drawn from the same elite level of competition, the expert decision-makers differed from the less skilled in having accrued, during their developing years, more hours of experience in structured activities of all types, in structured activities in invasion-type sports, in invasion-type deliberate play, and in invasion activities from sports other than Australian football. Accumulated hours invested in invasion-type activities differentiated between the groups, suggesting that it is the amount of invasion-type activity that is experienced and not necessarily intent (skill development or fun) or specificity that facilitates the development of perceptual and decision-making expertise in this team sport.

Les débats publics suscités par la création des Expos de Montréal

Les années 1960 au Québec sont marquées par un vigoureux courant nationaliste prônant l’affirmation politique et culturelle des francophones dans la province. Également, le phénomène de l’américanisation du territoire québécois s’accélère. C’est dans ce cadre historique particulier que naissent en 1968 les Expos de Montréal, équipe du circuit de baseball le plus important au monde, soit la Ligue du baseball majeur. La MLB s’installe alors dans un territoire où le baseball est centenaire. L’objectif de ce mémoire est d’étudier les débats et réactions suscités par l’avènement de Montréal dans le baseball majeur, en déterminant l’influence qu’y ont joué le nationalisme québécois des années 1960, l’américanisation du Québec et la longue histoire du baseball dans la province. Si les deux communautés linguistiques de celle-ci sont ici à l’étude, il n’en demeure pas moins que l’attention est davantage portée sur les francophones que les anglophones. En effet, ceux-ci ont semblé davantage interpelés par la création des Expos. D’ailleurs, parmi les deux groupes, les positions les plus documentées sont celles des chroniqueurs sportifs, qui se retrouvent donc au cœur de notre étude. Les opinions d’amateurs de baseball, de politiciens, d’hommes d’affaires ou de simples citoyens québécois sont également rapportées et analysées, mais dans une plus faible mesure.

As bolas paradas no futebol jovem – A opinião dos treinadores

As bolas paradas têm ganho importância no futebol nas últimas décadas devido à sua influência no resultado final dos jogos. No entanto no futebol jovem ainda são poucos os estudos neste âmbito. O objetivo deste estudo foi auscultar a opinião dos treinadores acerca da importância das bolas paradas no futebol jovem, nomeadamente as diferenças relativamente ao futebol profissional, os exercícios utilizados no treino, a importância do lado estratégico e como potenciar o aparecimento de especialistas nestes lances. Foram entrevistados seis treinadores com experiência na primeira liga portuguesa de futebol, tendo sido utilizada a entrevista semi-estruturada como instrumento de recolha de dados. A análise e interpretação do conteúdo das entrevistas permitiu identificar que os treinadores consideram que o treino destes lances no futebol jovem deve ter características diferentes do futebol profissional, que os exercícios de treino no futebol jovem devam ser direcionados para a aprendizagem do jogo e dos seus princípios. Quanto ao lado estratégico indicaram que é mais relevante nos escalões mais avançados e nas competições nacionais. Para a potenciação do talento existe a necessidade de maior volume de treino destes lances específicos e também treino individual.
