fear and nerves often cause a bowel movement - it's the bodies way of preparing for action. Why will having a great mass of poo in you help you play better? go and poo before the game

Poo before game and relax

I think its a good thing if you are relaxed. you'll get the poo out of your system and you wont get constipated or have to worry bout it. if you are relaxed you'll be able to concentrate more on your game

Dude if you need to take a dump then take a dump, if you were a powerlifter it would be very much required that you poo, or you might just end up crapping yourself on your lift, and nobody wants to see that :/

for the ease of the playing of the sport, poo

Better than going during the game.

"My friend told me". As usual followed by complete garbage.

If you need to go, you go. If you need to go and you don't go there's a good chance of an very embarrassing situation arising.

My friend told me that I shouldn't poo before playing a game of football as it relaxes you too much, just wanted to know how much truth there is in this and whether its similar reasoning for the likes of Ali not having sex before big fights
