SILVA, Adelino Sanchez Ramos da; PAPOTI, Marcelo; PAULI, José Rodrigo and GOBATTO, Claudio Alexandre. Preparation of percentile tables through anthropometric, performance, biochemical, hematological, hormonal and psychological parameters in professional soccer players. Rev Bras Med Esporte [online]. 2012, vol.18, n.3, pp.148-152. ISSN 1517-8692. http://dx.doi.org/10.1590/S1517-86922012000300001.
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 (P0, P15, P30, P50, P70, P85 e P100) was used to present the results. CONCLUSION: The elaboration of the percentile tables can be used as comparison reference for further studies.
