Resumen
Currently, performance control through monitoring fatigue and recovery in elite football is essential. Thus, the analysis of cortisol, for its usefulness, is configuring a tool to be used. During the 2018 FIFA World Cup in Russia, the Costa Rican national team opted to analyse players' cortisol concentrations to obtain an individualized profile of the players (Moreira et al, 2019). With this profile, cortisol was analysed for 3 days before the match in order to establish a profile predictor of performance in competition (Crewther et al, 2018). Among the results obtained, we observed a relationship between increases in the CAR (cortisol Awakening response) and subsequent performance, in the form of defeat or victory (González et al, 2018; Jimenez el al, 2012; Ratzi et al, 2018). Also, the correlation of cortisol analyses with external load markers (GPS) has been seen as a sensitive marker for the control of exerciseinduced fatigue (Minetto et al, 2008). In addition, the analysis of how the specific demands of the position influence the dynamics of recovery, with modifications of cortisol, are necessary to establish concrete profiles by playing positions (Gonzalez et al, 1999)). In addition, due to the hourly change product of the flight in a clockwise direction and the changes in circadian rhythms, it seems essential to control the effects of sleep disturbances and how they could affect performance, prove as depravations in sleep in 24 hours alter and increment the concentrations of cortisol (Minetto et al, 2008) with decreases in performance.
