Dermatoglyphics in sports sciences: Understanding the distribution of quantitative indicators in non-athletes and athletes of basketball according to their performance

Objectives. One of the concerns of Sports Sciences is the search for methodologies that can help discover potential athletes. In this sense, some initiatives have been taken in an attempt to identify and characterize the genetic profile of dermatoglyphic marks (fingerprints). The present work has the objective of understanding the distribution of quantitative dermatoglyphic indicators in basketball players with different levels of performance compared to non-players. Methods. The subjects observed constituted 125 individuals, divided into five numerically equal groups, three of which were composed of professional basketball players according to their level of participation (Brazilian Team, National Championship and São Paulo Championship) and the last two formed by weekend players and non-players, respectively. Eleven dermatoglyphic variables were analysed in the descriptive level by means of measurement of position, variability and limits of confidence of the median, and, in inferential terms, the Kruskal-Wallis statistical test was adopted. Results. The more expressive ones were: TRC, counting lines a-b and A'-d, behave differently between athletes and non-athletes. Conclusion. Studies about this kind of analysis should be continued, calling on resources that take into consideration all variables simultaneously as a multivariate study. © 2012 Revista Andaluza de Medicina del Deporte.

Sports injuries among adolescent basketball players according to position on the court

Background: The participation of children and adolescents in sports, including basketball, is becoming increasingly common, and this increased involvement raises concerns about the potential risk of sports injuries. Objective. To analyze the occurrence of sports injuries among young basketball players according to their position on the court and to associate these injuries with risk factors. Method. A retrospective, epidemiological study. A sample consisting of 204 basketball players with a mean age of 14.33 ± 1.19 years participated in the study. The players were interviewed using a reported condition questionnaire containing anthropometric and training data as well as information on injuries during the previous 12 months. Results: The frequency of injury was highest among the shooting guards (47.8%), followed by the centers (34.8%) and point guards (17.4%). Among the 204 participants, 40 players reported a total of 46 injuries, representing 0.22 injuries per participant and 1.15 injuries per injured participant. For the shooting guards and centers, statistically significant differences between injured and non-injured players were found related to age, weight, height, length of time in training and number of weekly practice hours (p < 0.05). For point guards, a statistically significant difference between injured and non-injured players was found based on weight alone (p < 0.05). Conclusion: The occurrence of injuries among basketball players was low. Injuries were associated with both intrinsic and extrinsic factors among shooting guards and centers, whereas injuries were only associated with weight among point guards. © 2013 Vanderlei et al; licensee BioMed Central Ltd.

Acute Phase Responses of Different Positions of High-Goal (Elite) Polo Ponies

The aim of this study was to investigate the acute phase response (APR) in 15 horses by quantifying physiological venous blood variables and serum acute phase proteins (APP) at 5 minutes and 6 and 12 hours after a training match of high-goal polo. The horses were divided into three experimental groups based on their team positions, including defense (n = 6), midfield (n = 5), and attack (n = 4). Serum proteinograms were obtained by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). Data were evaluated using analysis of variance for repeated measures. The match represented a high-intensity stimulus for all positions. Defenders appeared to use the anaerobic pathway more than the other positions, as shown by their lower pH and greater lactatemia. Alterations in muscle membrane permeability were observed in all horses, as seen by the increase in serum creatine kinase activity without a correlation with APR. Significant elevations in total serum protein, albumin, ceruloplasmin, haptoglobin, alpha-1 antitrypsin, and 23-kDa protein were seen only during the course of the physical exertion of the match, although there were no differences in these values among positions of the team. After 6 hours of the match, the concentration of transferrin declined, whereas that of alpha-1 acid glycoprotein remained unaltered at all assessed times. These results demonstrated that the defenders required the most use of the anaerobic pathway during the match, and that equestrian polo exercise triggers an acute phase response of relatively short duration; this APR is characterized as noninflammatory, as APR appears to be a physiological alteration related to the stress inherent in physical exercise. © 2013 Elsevier Inc.

Formação e renovação dos governos do Pará: elite governamental e grupos políticos (1983-2006)

O presente trabalho teve como objetivo central identificar quem são as Elites Governamentais que compuseram os Governos do Pará entre 1983 e 2006, a partir da metodologia de análise proposta pela Teoria das Elites. Nosso objeto de estudo foram os documentos intituladosTermos de Posse, arquivados na Secretaria Estadual de Administração (SEAD), onde se registram as nomeações do Secretariado de Estado e cargos afins. Utilizando-se do método da Posição Institucional foi detectado um Grupo Político formado a partir da composição de cada Governo investigado e, deste grupo, são selecionados os nomes que passaram a compor outros Governos, denominados “elite duradoura”. Cada membro desse último grupo corresponde a uma Conexão, que podem ser entre dois, três, quatro ou mais gestões. Analisando estes dados à luz do elitismo, produzimos um “índice de elitização” (IE), que compara o quanto cada Governo produziu, percentualmente, de nomes que compuseram a “elite duradoura”.

The Grounding of Regional Integration for Brazil: Universalism, Sovereignty and Elite Perception

The aim of this article is to analyse the meaning of Mercosur for Brazilian foreign policy. To this end, we discuss the perceptions of the Brazilian elites concerning the regional integration process. The defence of the principle of inter-governmentalism is related to the conception of Mercosur's place within Brazil's international relations. The fact that principles such as universalism and sovereignty are very highly valued ends up affecting the deepening of the integration. The hypothesis of this article is that the Mercosur structure is in line with the perceptions of part of the Brazilian elites, which has put less emphasis on integration since the late 1990s. Our argument is that the current structure is insufficient to guarantee the dynamics of integration.

O número de técnicos e técnicas que comandam equipes masculinas e femininas

It is known that gymnastics and sports, for the most part, were made by men for men, and its practice was almost exclusively for males, especially until the First World War. Vestiges of this strong male influence in sports still remain to this day, especially in leadership positions. It is clear that most sports, both male and female, are mostly coached by men. Thus, this study aimed to examine, through quantiqualitative research, the number of women and men who lead male and female volleyball, basketball and soccer elite teams, participating in the most important national championships, and the number of men and women graduated in physical education courses in Brazil in order to check a possible relationship between the low number of women working as a coach and the percentage of women graduated in physical education. For the acquisition of data, Internet searches were made on the sites of confederations, leagues and sports leagues selected for the study, and on the site of the National Institute of Educational Studies Anísio Teixeira (INEP). It was identified that the total number of graduates from 1995 to 2008 was 192,707, with 99,869 men and 92,838 women, showing a balance between these numbers, which did not happen with the numbers of male and female coaches. The data indicated that no women worked as a coach in male and female volleyball teams in the seasons 2006 to 2010, no woman worked as a coach in the male basketball teams in the seasons from 2000 to 2010, and only an average of 1.67 women led female basketball teams in the seasons 1998 to 2010, and no woman has ever worked as a coach for male soccer teams, while only an average of 2.67 women acted as a coach of female soccer teams. The difference between the number of men and women graduated in physical education is small and does not justify the low ...(Complete abstract click electronic access below)
