Just wish to shed my own views on this topic since everyone keeps saying football is meatheads bashing skulls in and parkour is much safer. First, every sport has a specific set of injuries commonly seen amongst athletes involved in the sports (ex. your not going to see a track runner getting tommy john surgery). So, every sport has inherant (sp?) risks involved. PK is no different. I've been playing football for going on 7 years now and not once have I received any major injury. I've only recently started parkour (a few months) and haven't even received a minor injury. Realistically, parkour has an injury rate that is probably very comparable to other sports. As the others above mentioned, the amount of risk can be increased or decreased in parkour which is what makes it so great. The reason why I haven't received injuries while some others have is because I train to make sure my muscles can handle the work load being placed upon them. If you have any weak point in your body, it will be revealed when you train. Rid yourself of these weak points and your body will be able to handle much more stress and your risk of injury will be reduced greatly. A great visualization is of a chain. A chain with a weak link will break much much easier than a chain that has none. Hope this helps.
