Different school's have different levels of contact rules during sparring. (ex: no contact, light, moderate, and full) Why is this? Are all contact levels effective? Our school only allows up to moderate level strikes. We had a black belt from Germany come to our program and his school had only no contact sparring. At first he was a bit awkward with the contact, but after a month he was actually pretty good. I don't know if that was just a specific case, of his ability do adapt to our style, or if it isn't an easy transition to be able to go from different levels of contact. So for example if you have never made contact during sparring will you be able to adapt to a situation were you need to use full, or lethal contact on the street, or any dangerous situation?
