Football clubs are always looking for new ways to prevent and reduce the number of injuries that they inevitably experience each season and Napoli has one rule that it credits with keeping its number of muscle injuries low: No sex for two days before each match.

From Football Italia:

"Avoiding sexual activity for two days before a game is fundamental to prevent muscular strains, contractions or inflammations," Professor Alfonso De Nicola [Napoli's chief medic] told the Corriere del Mezzogiorno newspaper. "It is the rule for our squad. There is also a specific work done by my staff and the fitness coaches which is aimed more at prevention than cure."

Whether the sex ban is the reason or not, Napoli has had a low number of muscular injuries. Still, this seems like a harsh rule and one that is probably very impractical for wealthy young footballers. Then again, Milan midfielder Kevin-Prince Boateng's girlfriend did blame his thigh injury last season on their practice of having sex 7-10 times per week.

Making recommendations against certain, especially acrobatic positions would probably be more practical. Also, banning Marek Hamsik from biting the heads off his partners immediately after the act would probably be a good idea for legal reasons.
