Efeitos do treinamento sobre variáveis psicofisiológicas pré-temporada de futebol

Abstract

Objective: to verify the effect of training load in biochemical, psychological, physiological and hematological variables during a pre-season in professional soccer players. methods: Eight male professional soccer players were monitored for 21 days during a pre-season and submitted to four evaluations (t1, t2, t3 and t4). the variables analysed were: hemoglobin, creatine kinase, poms questionnaire and heart rate variability in time and frequency domains. the load of each training session was quantified using the trimp method. results: creatina kinase increased significantly (p<0.05) in t2 and t3 with respect to t1, following the behaviour of the training load. the other variables showed no significant difference (p>0.05) and no correlations between variables were found. conclusion: it seems that creatina kinase is the most sensitive variable to training load compared to the other variables. heart rate variability values in frequency domain presented a trend in response to changes in training load.
