Acute Injuries happen suddenly. The injury can be due to direct impact such as falling from a mountain bike and banging your head or more indirectly as in slipping on a badminton court while lunging and creating a groin strain.
Often the result of unaccustomed or excessive exercise, examples might be shoulder pain after a vigorous game of squash or too many overs of bowling in a cricket match.
