Análise transversal da estrutura óssea e parâmetros hematológicos em futebolistas profissionais

Abstract

The analysis of the variables of body composition, physical performance, bone structure and blood markers in different periods and situations on professional soccer players, is an important factor when we search the maintenance of the performance, in the perspective of sporting career of athletes over the years and in the prevention of injuries in this sport. The objectives of this study were: To compare the bone structure of professional´s soccer players of white and black race during the competitive period; and, describe and compare the hematological parameters of soccer players during the competitive period on function of the game positions and determine the anemia prevalence. Were participated of these analysis 38 professional soccer players in the age range from 19 to 33 years, belonging to a professional club of the first division of Brazilian soccer. Were analyzed the indicators of body composition, the indicator of physical performance, the indicators of quality and quantity bone and the hematological parameters. The physical performance was explored in the indicator of aerobic power (VO 2máx ), through the specific test of field: Yo-Yo Intermittent Recovery Test level 2. The variables that characterized the body composition were: fat mass (MG); stature (EST); percentage of body fat (%G), through measures of body mass, lengths and skin folds. The participants were subjected to qualitative ultrasound of no dominant hand phalanges to verify the bone quality and quantity (AD-SoS e UBPI). The hematological parameters were analyzed by intravenous blood test in fasting. The experience and the time of training were included in the amount of years of training experienced by the soccer players. The results indicate that the professional players of black race present a better bone structure in their phalanges in the no dominant hand in relation to those of white race. And there are no differences in hematological parameters of players of different tactical positions, as well as there are no prevalence of anemia in these professional soccer players.

Estudo do crescimento físico, composição corporal, saúde óssea e desempenho físico de crianças e adolescentes praticantes de beisebol brasileiro

“…Há, por exemplo, uma alternativa que avalia a composição corporal que é considerada de baixo custo e de fácil administração é a antropometria que, assim como qualquer outra área da ciência, depende de regras específicas, padronizadas para a determinação da localização de pontos e técnicas internacionais para a mensuração corporal (MONTEIRO e LOPES, 2009). Esse método é de boa reprodutibilidade e facilidade para tratar do desenvolvimento do corpo humano e das relações existentes entre os aspectos físicos e a performance, considerada também a "área base" para o estudo do desenvolvimento corporal (MEISEL; VEJA, 2016; FREITAS, 2018) e permite inferir a quantidade de massa gorda, muscular, óssea e residual que as pessoas têm em determinado momento que são valores necessários para equações de regressão a partir dos quais é possível prever o percentual de gordura corporal de um sujeito com base na idade e sexo (SANTI MARIA, 2013).…”
