Background: Impaired inhibitory control has been related in individuals with substance use disorder (SUD). Cardiorespiratory fitness has been shown to improve cognition in different populations. Aims: Investigate the relationship between cardiorespiratory fitness and inhibitory control. Methods: Sixty-two male participants under treatment for SUD performed a general and drug-specific inhibitory control test (Go/No go) and a cardiorespiratory fitness test. Results: Cardiorespiratory fitness, age and time of use of substance were inversely associated with reaction time for both specific (r=-0.472, p<0.001) and general inhibitory control (r=-0.430, p<0.001). Regressions sho w that cardiorespiratory fitness controlling for age and time of drug use predicts specific [F (8.7; 3); t = -3.22; β = -0.420; p < 0.002] and general inhibitory control [F (6.6; 3); t = -3.06; β = -0.415; p < 0.003]. Conclusions: These findings suggest that cardiorespiratory fitness is an independent predictor of cognitive inhibitory control in individuals with SUD.
