Possibilidades de organização de campeonatos de basquetebol e voleibol sub 1,80m masculino

Currently in the sports world, one of the prerequisites imposed by the organizers of sports sieves (selection of athletes) is the height, it becomes increasingly essential to play in clubs and teams worldwide. We noticed that teams base categories also suffer greatly from this height limitation. The objective of this research is to investigate the opinion of coaches, former coaches, players and former players and basketball players and volleyball on that possibility, or what to think about creating sub 1.80 m championships in men's tournaments. . This is a study of the qualitative and descriptive conducted with athletes and coaches volleyball and basketball courts, 6 volleyball players, six basketball players, volleyball players and a coach second technical basketball. We had the result of this work three main parameters: If athletes and coaches are in favor or not the creation of leagues, if there is any form of prejudice with the low in basketball and volleyball and opinions about the players lower in basketball and volleyball. Small players adhered to the idea of creating the league, high players were divided in high response and the coaches agreed saying that it grows with the Sports. Next step is the implementation, planning for these championships to assess the real possibilities of success of this initiative.

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)

Diferença no número de técnicas e técnicos no voleibol: uma análise das categorias de base até o adulto

Voleyball is a sport that has gained an important contingent of public, achieving a growing visibility especially in recent years. Despite being a very democratic sport, as it is practiced by both men and women, it can be observed that there are differences when the analysis refers to who is in charge of the teams. So the purpose of this study was to analyze the presence of women in the country volleyball (coaches) from base categories to the professional adult, through a documental research. Data were collected from electronic documents, official websites and websites of federations teams. The results indicated that the number of women coaching volleyball athletes is minimal, revealing the difference between the professional treatment given to male and female genders. Therefore, it became clear that certain discrepancies are caused not only by lack of professionalism, but also by the cultural characteristics that still consider the place of women as domestic and not in the command of field sports

Exercise and oxidative stress: p,otential effects of antioxidant dietary strategies in sports

Free radicals are produced during aerobic cellular metabolism and have key roles as regulatory mediators in signaling processes. Oxidative stress reflects an imbalance between production of reactive oxygen species and an adequate antioxidant defense. This adverse condition may lead to cellular and tissue damage of components, and is involved in different physiopathological states, including aging, exercise, inflammatory, cardiovascular and neurodegenerative diseases, and cancer. In particular, the relationship between exercise and oxidative stress is extremely complex, depending on the mode, intensity, and duration of exercise. Regular moderate training appears beneficial for oxidative stress and health. Conversely, acute exercise leads to increased oxidative stress, although this same stimulus is necessary to allow an up-regulation in endogenous antioxidant defenses (hormesis). Supporting endogenous defenses with additional oral antioxidant supplementation may represent a suitable noninvasive tool for preventing or reducing oxidative stress during training. However, excess of exogenous antioxidants may have detrimental effects on health and performance. Whole foods, rather than capsules, contain antioxidants in natural ratios and proportions, which may act in synergy to optimize the antioxidant effect. Thus, an adequate intake of vitamins and minerals through a varied and balanced diet remains the best approach to maintain an optimal antioxidant status. Antioxidant supplementation may be warranted in particular conditions, when athletes are exposed to high oxidative stress or fail to meet dietary antioxidant requirements. Aim of this review is to discuss the evidence on the relationship between exercise and oxidative stress, and the potential effects of dietary strategies in athletes. The differences between diet and exogenous supplementation as well as available tools to estimate effectiveness of antioxidant intake are also reported. Finally, we advocate the need to adopt an individualized diet for each athlete performing a specific sport or in a specific period of training, clinically supervised with inclusion of blood analysis and physiological tests, in a comprehensive nutritional assessment.

Possible underestimation by sports medicine of the effects of early physical exercise practice on the prevention of diseases in adulthood

In modern society, combatting cardiovascular and metabolic diseases has been highlighted as an urgent global challenge. In recent decades, the scientific literature has identified that behavioral variables (e.g. smoking, unhealthy diet and physical inactivity) are related to the development of these outcomes and, therefore, preventive actions should focus on the promotion of physical exercise practice and a healthy diet, as well as combatting the smoking habit from an early age. The promotion of physical exercise in the general population has been suggested as a relevant goal by significant health organizations around the world. On the other hand, recent literature has indicated that physical exercise performed in early life prevents the development of diabetes mellitus, dyslipidemia and arterial hypertension during adulthood, although this protective effect seems to be independent of the physical activity performed during adulthood. Apparently, the interaction between physical exercise and human growth in early life constitutes an issue which is not completely understood by sports medicine. The aim of the present review was therefore to discuss recent evidence on the effects of physical exercise performed during childhood and adolescence on cardiovascular and metabolic outcomes in adulthood.
