Why Athletes Do It Better: The Science of Sex

For decades, sports physiologists pondered the following question: does sex, especially the night before a big competition, hinder athletic performance? While the answer might be of interest to coaches and Olympiads trolling the Beijing streets the night before their long jump, it has little relevance for the rest of us, who aren’t competitive athletes. A recreational runner or pick-up basketball player isn’t likely to be setting world records. They are, however, likely to be having (or wanting to have) sex. Therefore, a more relevant question for the masses is the corollary: how does exercise affect our sex lives?

Not surprisingly, research indicates that exercisers have more and better sex than couch potatoes. The agility and flexibility garnered during sports can help during sex, an athletic endeavor in its own right. But exercise has implications beyond just the physical. It affects our mental, emotional, and psychological state of being; this in turn positively affects our sex lives.

One benefit of exercise has to do with perceived body image. A 2004 study published in the Electronic Journal of Human Sexuality questioned 400 college students and found that regular exercisers had higher levels of self-confidence, perceived themselves to be more sexually desirable, and had higher levels of sexual satisfaction than their non-exercising peers. Feeling sexy can help stimulate sexual desire, so it makes sense that those with improved body image would be inclined towards more sex.

Exercisers also tend to be more aware of their bodies and feel more comfortable with them. And because exercise can reduce stress and elevate mood, it helps us relax—all attributes which help out in the bedroom.

Similarly, physically active people rate their own sexual performance higher than sedentary peers. This could be because of perceived body image or increased self confidence (or narcissism), but also because of improved muscle tone, endurance, or body composition.

The benefits of exercise aren’t just reserved for those in their youth, who tend to be both healthier and hornier than older populations. A Harvard University study looked at 160 swimmers in their forties and sixties and found a positive relationship between regular exercise and sexual satisfaction and frequency. Swimmers in their sixties reported sex lives comparable to those in their forties, indicating that if you move it, you don’t have to lose it.
