Deteção e seleção de talentos em andebol : diferentes perspetivas

In seeking to maximize athletic performance, optimizing the improvement of players, we find a line of study that focuses on the detection, selection and talent development. The talent is one of the fundamental constraints to access to excellence in competitive sport. Its identification is the first step to select individuals with the characteristics required to achieve the improvement sports through a complex process of expertise. The aim of this work is essentially to realize how it is made detection and selection of talent in Handball and understand how countries reference to the sport develop their work. In this sense, we choose in addition to Portugal, France, Spain and Denmark. We want to see how these four countries invest and develop detection and talent selection, taking into account the different characteristics of countries in many different contexts. So we can see that each country invests in talent selection and detection taking into account the financial capacity, the development and popularity of the sport. In all three countries, with the exception of Portugal, the Handball is a sport with great impact not only through their championships as well as the level of selections. All invest in detection and selection of talents initially by direct observation and collection of anthropometric data, and organize their structure depending on the size of your country. With the exception of France all other countries after detecting the taletos, fits us in selection schemes open. France chooses to create training centers where these young people will develop their skills. These centers are autonomous although the supervision and guidance of the technical staff of the federation. All countries except Portugal, opt to develop regional selections, thereby widening the recruitment base within a competitive framework extra club.

The structure of domination today: a lacanian view

Na era da sensibilidade extrema em relação ao assédio do Outro é cada vez mais comum submeter à crítica, injunções éticas, que nos aterrorizam com a sua imposição brutal do universal. Lacan explica esta violência ética através da passagem do discurso do Amo para o discurso da Universidade enquanto discurso hegemónico da sociedade contemporânea.

Reported Use of Anabolic Steroids and Ergogenic Substances in Gym/Health Club Settings: Associations with Psychosocial and Exercise Behavior Factors

The industry of ergogenic supplements is increasing rapidly (Cole et al., 2003). Supplements may constitute an important aid for some vigourous exercise routines, but they may also be used as a hypothetical mean to achieve increases in muscular mass. This supposed effect of suplements can lead to its use by individuals who have high levels of drive for muscularity, a condition that is known to be associated with muscular dismorphy (or as it has been called recently vigorexia, Pope et al., 1997). Another psychological factor which can influence supplement consumption is exercise dependence, a borderline problem, as most studies present a prevalence of less than 10% in regular exercisers (Palmeira & Matos, 2006). Symptoms like tolerance or continuity could lead to the use of ergogenic aids to maintain the exercise levels. Also of interest for the understanding of the use of suplements are exercise frequency, volume and intensity, which could explain the ratesof consumption on a more physicological level.

Ball Recovery in the Handball Tournament of the 2008 Beijing Olympic Games: Sequential Analysis of Positional Play as Used by the Spanish Team’s Defence

In sport there is a great need to obtain as much information as possible about the factors which affect the dynamics of play. This study uses sequential analysis and temporal patterns (T-patterns)to examine the evolution of defence (against an equal number of attackers)as used by the Spanish handball team at the Beijing 2008 Olympic Games. The aim is to help handball coaches (during their training and gathering of professional experience)to understand the importance of the structure of defensive systems. This can be achieved through observational processes that reveal the evolution and adaptation of these defensive systems according to different variables: the match score, the response of the opposing team and progress through the tournament.

The East Atlantic Bluefin Tuna Fisheries: Stock Collapse or Recovery?

A discrete time, multi-gear, and age structured bio-economic model is developed for the East Atlantic bluefin tuna fisheries, a paradigmatic example of the difficulties faced in managing highly migratory fish stocks. The model is used to analyse alternative management strategies for the Regional Fisheries Management Organisation (RFMO) managing this fishery, and to investigate some of the policy implications. For the various scenarios, the optimal stock level varies between 500–800,000 tonnes, which compares with a stock level of 150,000 tonnes in 1995. In other words, there is a very strong case for rebuilding the stock. Moreover, the sustainability of the stock is threatened unless a recovery programme is implemented; indeed, the alternative may be stock collapse. Second, to rebuild the stock, Draconian measures are called for: either outright moratoria over fairly lengthy periods, or possibly a more gradual approach to steady state given by a Total Allowable Catch (TAC) at a low level for an extended period of time. Third, the cost of inefficient gear structure is very high indeed.
