Abstract Overtraining syndrome is a chronic situation that results from long periods of high intensity and volume work without rest periods. The purpose of this study was to determine the relationship between plasma testosterone and cortisol concentrations with psychological overtraining items (by Consensus group on overtraining of the Societe Francaise de Medecine du Sport) in football referees. Thirty football referees (X±SD: age 28.9±4.54 year; height 178.9±6.45cm; weight 77.5±9.23 kg; BMI 22.96±2.14 kg/m2; Vo2max 51.21±2.53 ml/kg/min) volunteered for the study during a rest day (24 hours without training). They were asked to complete the overtraining questionnaire contains 54 question requiring answers of “yes” or “no”. Then plasma samples were taken at rest and immediately after agame of Isfahan premier league (vision of Asia). The results of data analyses showed that the overtraining score from questionnaire correlates with cortisol concentration on rest day respectively (r=0.71), and testosterone/cortisol ratio (r=-0.42; p<0.05). Result show that the questionnaire may be a useful tool for monitoring and preventing of overtraining syndrome.
