Introduction: Research has shown that exercise increases levels of dopamine in cer tain sub - cortical brain regions. Increased dopamine activity in the brain has been linked to increased risk - taking. The purpose of this study was to determine if an increase in risk - taking is apparent in male athletes and non - athletes after strenuous exercise. Method: Ten athletes (age: 20.2±SD year) and ten non - athletes (age: 20.7±SD) in a university setting completed the BART (a validated protocol to asses risk - taking behavior) either after exercise or at r est. Result: Athletes obtained total 24.92 ± 10.99 pumps and Non - Athletes 42.76 ± 16.45 pumps . Discusion: AN C OVA’s showed that there was significant difference between athletes and non - athletes ( p< 0 .0 1) on the risk behavior test. Post hoc tests showed that for non - athletes there was also a significant difference for those that exercise immediately before the risk behavior test, p= 0 .003. This was not the case with athletes, p= 0 .683. Results indicate that while exercise increased risk - taking in the non - athlete subjects, it did not have an effect on the athlete population.
