“…12 On the contrary, eosinophils had two sequential peaks, yet both were nonsignificant and within the reference range ( Table 2). This result differs from that found by Silva et al 19 and Coswig, Neves and Del Vecchio, 20 who mention that a smaller number of eosinophils is observed in athletes experiencing the effects of overtraining due to the overload that triggers injuries and inflammation.…”

Introduction: Soccer players may experience hematological changes that could be detrimental to their health status. In addition, inadequate body composition may impair performance. Objective: To assess body composition and hematological changes over a year in soccer players. Methods: A retrospective observational study was conducted. Age, weight, height, body composition, blood count, serum iron, serum ferritin, serum transferrin and total iron binding capacity data were collected from the athletes’ medical records in the months of January, May and August of 2015 and January of 2016. Body mass index was also calculated. For the statistical analyses, the Anova and post-hoc Tukey’s post-hoc tests were used for the quantitative variables and the Chi-square test for the qualitative variables. The significance level adopted was p<0.05. Results: Data were evaluated for 51 athletes with a mean age of 23.53 ± 3.11 years, 77.10 ± 6.56 kg, 1.80 ± 0.07 and 15.6 ± 2.89% body fat (BF). We observed significant (p<0.05) changes in mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, cell size and eosinophils during the period evaluated. Among the athletes, 21.6% had decreased hematocrit levels and 3.9% had hemoglobin levels below the reference range. A BF% greater than 16% was significantly related to serum iron depletion (p = 0.01). Conclusion: Small significant hematological changes during the competitive year were observed, but without significant changes in body composition. Level of Evidence III; Study of nonconsecutive patients; without consistently applied reference ‘‘gold’’ standard.

“…In general, studies do not suggest preference of material for analysis, meeting those using blood cortisol (COSWIG; NEVES; DEL VECCHIO, 2013;CRUZ et al, 2012. ), the salivary cortisol (ARRUDA et al, 2013a;2013b;MORAES, 2010), beyond the combined analysis of serum and salivary cortisol (PAZIKAS;CURI;AOKI, 2005).…”

“…By analyzing the monographic research using cortisol as a marker of stress in humans, gave great representation of studies with athletes, an aspect that is also featured in the scientific literature (ARRUDA et al, 2013a;2013b;COSWIG;NEVES;DEL VECCHIO, 2013;CRUZ et al, 2012;MORAES, 2010;SILVA;MACEDO, 2011).…”

“…In this important assessment of this group of humans who are exposed to stressful events in greater magnitude scenario, the analysis becomes relevant in hormonal concentrations that can be correlated with the planning of training, because the increase in baseline testosterone indicates adequate training and recovery, while elevation of cortisol suggests organic overload and inadequate adjustment (COSWIG; NEVES; DEL VECCHIO, 2013).…”

To Identify in dissertations and theses available on Brazilian Theses database of Coordenação deAperfeiçoamento de Pessoal de Nível Superior (CAPES) information about the effects of cortisol as marker of stress; characterize the sample of the study. Study of literature review narrative, descriptive, the data were collected in February 2013, in pairs, following the research protocol previously established. There were analyzed 89 dissertations and theses in the light of the pillars: academic level; place of the study development; year; author's formation; the study population; the generator element of stress; and material analyzed. The majority of the studies denoted a significant change on the cortisol level through exposure to stress generator element (74; 83.1%), revealing that this is a good marker of response to stress. It was noticed that there is a need to promote the development of clinical research with human beings, especially as health professionals.

ResumoCom as mudanças no estilo de vida, hábitos alimentares e novas metodologias de treinamento tornam-se importantes pesquisas científicas, para preencher as lacunas no conhecimento antropométrico e nutricional, com finalidade de melhora na aptidão física e desempenho durante as competições e treinamentos para atletas de artes marciais e esportes de combate. O presente estudo teve como objetivo avaliar o conhecimento e estado nutricional assim como relacionar com a percepção da imagem corporal em lutadores de artes marciais. Avaliou-se 37 atletas, que praticavam diferentes modalidades de artes marciais provenientes de duas academias na zona oeste de São Paulo. Para determinar o estado nutricional foram mensuradas a massa corporal, estatura e dobras cutâneas; também a percepção da imagem corporal e o conhecimento nutricional. A amostra apresentou em média 25,8 ± 5,8 anos, 84,4 ± 15,8 kg, 1,76 ± 0,07 m e percentual de gordura de 14,1 ± 5,5. A média do índice de massa corporal foi de 26,95 ± 3,75 kg/m², classificando-os com sobrepeso. Dos lutadores, 70,27% apresentaram moderado conhecimento nutricional, 24,32% baixo conhecimento e o restante 5,41% alto conhecimento. Em relação ao estado nutricional, os lutadores apresentavam em sua maioria sobrepeso e percentual de gordura abaixo da média, com grande insatisfação de imagem corporal e moderado conhecimento nutricional. Palavraschave: artes marciais; esportes de combate; MMA; estado nutricional; imagem corporal. Evaluación del estado, conocimiento nutricional e imagen corporal de atletas de artes marciales mixtas ResumenCon los cambios en el estilo de vida, los hábitos alimentarios y en las nuevas metodologías de entrenamiento, es importante que la investigación científica explore las lagunas existentes en los campos de conocimiento antropométrico y nutricional, con el fin de mejora la aptitud física y el rendimiento de los atletas de artes marciales y deportes de combate durante las competiciones y los entrenamientos. El presente estudio tuvo como objetivo evaluar el conocimiento y estado nutricional de luchadores de artes marciales, y relacionarlo con la percepción de la imagen corporal. Se evaluaron 37 atletas practicantes de diferentes modalidades de artes marciales en dos academias en la zona oeste de São Paulo. Para determinar el estado nutricional se midieron la masa corporal, la estatura y los pliegues cutáneos. También se evaluaron la percepción de la imagen corporal y el conocimiento nutricional. La muestra presentó en promedio 25,8 ± 5,8 años, 84,4 ± 15,8 kg, 1,76 ± 0,07 m y un porcentaje de grasa de 14,1 ± 5,5. La media del índice de masa corporal fue de 26,95 ± 3,75 kg / m², clasificando a los atletas con sobrepeso. Un 70,27% del total de luchadores presentó un conocimiento nutricional moderado, el 24,32% un bajo conocimiento y el restante 5,41% un alto conocimiento. En cuanto al estado nutricional, los luchadores presentaron en su mayoría sobrepeso y un porcentaje de grasa por debajo de la media, con gran insatisfacción de imagen corporal y moderado c...
