coming from a volleyball player with past knee injuries, it really depends on how they train and what they train. volleyball training can build up muscles in the leg that help protect the knee part(?) and technique can really help to prevent injuries. from my past experiences, the ankles are more likely to get injured from all the jumping and landing(especially close to someone else as you can land on their limbs(which I did))
how much are their knees suffering? For all the high impact jumps to the squats they do... As a person who has chronic knee pain from a young age I just wonder how they would fare as they grow older QUQ
