Introduction: Research has shown that exercise increases levels of dopamine in certain 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 rest. Result: Athletes obtained total 24.92±10.99 pumps and Non-Athletes 42.76±16.45 pumps. Discusion: ANCOVA's showed that there was significant difference between athletes and non-athletes (p<0.01) 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.
