Have sex to boost your on field performance, advices Indian coach Kirsten to his players in the Champions Trophy.
According to Kirsten, if the players don't have a partner, they should simply imagine.
In a four-page document circulated among Indian cricketers, coach request every players to take on responsibility, concentrate on a healthy diet and also have sex.
"Yes it does, so go ahead and indulge," the document said, before detailing the benefits of a good sex life and even suggesting "going solo" if no partners were available.
"From a physiological perspective, having sex increases testosterone levels, which cause an increase in strength, energy, aggression and competitiveness," the document said.
"Conversely, not having sex for a period of a few months causes a significant drop in testosterone levels in both males and females, with the corresponding passiveness and decrease in aggression."
The document also contains quotes from Tim Noakes, a professor and sports scientist at the University of Cape Town, Kirsten's home town, as saying that "sex was not a problem, but being up till 2:00 am, probably having a few drinks at a bar while trying to pick someone up, on the eve of a game, almost always was."
The document helpfully suggests a solution.
"If you want sex but do not have someone to share it with, one option is to go solo whilst imagining you have a partner, or a few partners, who are as beautiful as you wish to imagine," the document said
