RESUMO

Competition athletes are subjected to muscular lesions that could be avoided or minimized if a biochemical, metabolic and emotional indicators follow-up were made during practices as a routine, resulting on an increase of the athletes sport life. The objective of this study was to measure the serum concentration of muscle-skeletal lesions biochemical markers and the psychological state of professional athletes from a soccer team playing at first division. 11 male athletes were evaluated with ages of 26,5 7,5 years, high of 1,73 meters ( 0,5 cm) and weight of 77,1 ( 3,8 kilograms). The gathering of data was made during the annual cycle of practices and games, always before practice in the morning, on six distinct periods of training: pre-season (PT), competitive period one (C1), competitive period two (C2), competitive period with a 72 hours interval after the last activity (recovering period) (C72), competitive period three (C3) and competitive period four (C4). Every day, before the blood sample collect to the biochemical evaluations, a questionnaire of attendance to the psychological variables was applied using the BRUMS scale. On biochemical blood evaluation, were applied serum doses of: creatine kinase (CK), lactato dehydrogenase (LDH), aspartate aminotransferases (AST) and alanine aminotransferases (ALT), magnesium (Mg2+) and calcium (Ca2+). The enzymatic and mineral values found for the analyzed period indicate significant variations when compared to PT. The concentration of CK, LDH and AST demonstrated a great sensibility to detect the risk of lesion when presents progressives and simultaneous increases for the analyzed period, while the ALT, Ca2+ and Mg2+ are not good markers to the risk control of a soccer lesion. The BRUMS scale showed a good reprodutibility to the evaluation of the psychological state of athletes under training, the most significant variables to the detection of lesions risk are fatigue and energy and they present significant correlation with the biochemical markers. 15 lesions were observed through the study, distributed on 11 athletes. The periods of major numbers of lesion for group 1 was C4 (3 lesions 75%) and for group 2 was C1 (3 lesions 60%). When the frequency and distribution of lesions on the observed periods are visualized, we can affirm that there are a tendency to occur a greater number of lesions in periods where we find greater increases of biochemical concentration, especially of CK, LDH and AST, also an increase of stress and fatigue, followed by a progressive decrease on energy. The results of this study indicate a very important relation between the physical wear caused by excessive training and emotional stress that appear in response to the organism aggression by the routine of practices and games of the professional soccer athlete. The need of biochemical and psychological control in training is evidenced by the identification of physical and mental wear, as well as to the practice of preventive actions seeking the preservation and increase of the athletes sport life.
