Nice responce, I would say for lower ranks that the sparring should be lighter and if on a regular basis contact does not have to be full power but can be full speed without doing a ton of damage. I still think there is a difference between hitting a bag where you are thinking about what you are doing and working off reflexes in fast sparring when it comes to range. I dont think sparring to the point of serious injury is at all wise but i think full contact means full speed and making proper contact but not needing to let the punch or whatever go all the way through. Unless you are training for a fight. Begginers can go light and slowbut still be making solid contact. It will hurt a little but do no damage, thats still full contact. So i still dont see a great deal of use for no contact sparring.
