The Rabbis of the Talmud decreed that having sex on Friday is a Mitzvah (a must do)! But I have a sneaking suspicion they didn’t have athletic performance in mind. On the other hand, for many years, football coaches, Olympic athletes, and even Muhammad Ali, have advocated sexual abstinence the night before an athletic event. Marty Liquori, one the world’s number one-ranked 5,000-meter runner believes that Sex makes you happy, and happy people don’t run a 3:47 mile. Marv Levy, head coach of the Buffalo Bills, insisted that the team be separated from their wives before their appearance in four Super Bowls; a policy that apparently was not successful (four losses out of four Super Bowls).
On the other hand, there are also plenty of anecdotal stories of athletes who claim to have benefited from sex the night before an event. Both U.S. track star David Wottle and Canadian downhill skier Karin Lee Gardner attribute their Olympic gold medals in part to their pre-race preparation.
