You can sustain an intentional injury like by flopping in basketball where you purposely try to get the referee to give your opponent a foul. You fall and act like you are hurt. In this act you put yourself at risk of actually getting hurt. An unintentional injury could be as a football quarterback and you are scanning the field of who you will throw to. All of a sudden you are hit from your blindside and hurt whatever body part as you go down. This was unintentional and you didn't mean for it to happen. Things that can reduce the risk of injury are staying out of foul trouble in a sport and making sure your body is ready to take hits that can come at any moment. You can prepare your body by stretching and loosening it up. Hope this helps!
