Elaboração de tabelas de percentis através de parâmetros antropométricos, de desempenho, bioquímicos, hematológicos, hormonais e psicológicos em futebolistas profissionais

Abstract

Introduction: The lack of reference values of anthropometric, performance, biochemical, hematological, hormonal and psychological parameters is an important limitation in the investigations with soccer players. Objective: To elaborate percentile tables to be used as comparison reference for further studies. Methods: 82 professional soccer players were evaluated approximately 30 days after the beginning of the main competition played by their teams. On the first day of evaluation, fast blood samples were collected for measurement of hematological parameters (i.e. erythrocytes, hemoglobin, hematocrit, mean corpuscular volume -MCV, mean corpuscular hemoglobin -MCH, mean corpuscular hemoglobin concentration -MCHC, leukocytes, eosinophils, lymphocytes, monocytes and platelets) and of concentrations of adrenaline, cortisol, creatine kinase, creatinine, norepinephrine, testosterone and urea. Subsequently, the soccer players had their anthropometric characteristics and psychological parameters assessed. In addition, the evaluation of the lactic anaerobic system efficiency was performed on a 400-m track. On the second day, both the alactic anaerobic and aerobic system efficiency was measured. Results: The percentile distribution (P 0 , P 15 , P 30 , P 50 , P 70 , P 85 e P 100 ) was used to present the results. Conclusion: The elaboration of the percentile tables can be used as comparison reference for further studies.

Hematological Parameters and Body Composition of Soccer Players

“…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.…”

Dynamics of Recovery of Physiological Parameters After a Small-Sided Game in Women Soccer Players

“…In addition to variables related to the cardiovascular system, the determination of injury biomarkers and physiological stress are also frequently used to determine the internal training load ( Nakamura et al, 2010 ; Souza et al, 2010 ; Coelho et al, 2013 ; Mazon et al, 2013 ). Previous studies have shown that both soccer training and formal games can alter plasma concentrations of catecholamines (adrenaline and noradrenaline), cortisol, testosterone, creatine kinase, and lactate dehydrogenase as a consequence of the efforts ( Coelho et al, 2011 , 2013 ; Silva et al, 2012 , 2014 ), which could be partially attributed to intermittent repetitions of intense eccentric activation ( Ispirlidis et al, 2008 ).…”

Conhecimento Nutricional E Estado Antropométrico De Atletas Universitários

“…Os atletas desse estudo possuem massa corporal total, estatura e IMC abaixo da média em comparação com jogadores profissionais de futebol 11 . Vale ressaltar que a classificação proposta por Silva et al 11 destina-se a atletas profissionais e deve ser analisada cuidadosamente, levando-se em consideração fatores que podem influenciar a composição corporal, como frequência, duração e tipos de treinamento a que são submetidos os atletas.…”

“…Recentemente, usando o protocolo de Durnin e Womersley 14 , em uma tentativa de estabelecer percentis que possam ser utilizados como referencial para atletas profissionais brasileiros, Silva et al 11 encontraram valores médios de %G 9,2 ± 3,1%.…”
