Karate is a combative / self-defence system, so over time small injuries are likely.
Training in the club is structured and supervised, and the aspect of safety always considered.
For a beginner, partner work begins with a form of sparring called “Gohon Kumite”. Some students will get bruises around their wrists initially, as the opponents strikes are blocked. You are unlikely to be ‘hit’ in this initial form of sparring as a beginner.
As your training progresses and you become a higher grade, then the forms of sparring become more difficult, and so different body areas are blocked (e.g. legs) and may initially bruise.
Training will be tougher for higher-graded adults, and as Kumite forms become more advanced then you can expect to be occasionally hit (though this will be with control - we are not talking about full-contact).
Other forms of injuries usually occur if the student hasn’t warmed up thoroughly at the start of the class (e.g. strained, pulled muscles).
