"We found that the biggest indicator was your preconceived notion of whether or not it would impact you," says Young.
The study, commissioned by Adam & Eve, included 11 male and 10 female collegiate or national-level track and field athletes. They surveyed the athletes' perceptions of having sex or masturbating before a competition, then recorded their actual performance and whether or not they'd had sex in the last week.
"The takeaway we found was that your own moral code or perception of what will happen will likely happen," says Young. Athletes who thought they should be abstaining were more likely to see a negative impact on performance if they'd recently had sex or masturbated, while athletes who thought sex would benefit them were more likely to see a positive impact on performance after getting laid. Huh.
