The reality of any physical activity is too much is bad for you. A real simple litmus test, as if its truly possible, for any physical activity would go something like this, 'is this going to make my body healthier now, in 10 years, & in 30 years'?
Take mountain climbing at altitudes above 10,000 ft, the answer is a resounding no. Meanwhile hiking is generally one of the better activities a person can undertake.
Skateborarding, I think it's a rather obvious no, unless doing long distances it's a lower-end cardio workout with a fairly high risk of injury depending on the style one is pursuing.
Walking, obviously yes.
Running, sort of skirts the line, but I'd say long term for avid runners it's a downer for bone, joint, soft tissues, & feet/legs but a boom to cardio etc. Translation, moderation is probably very healthy.
Soccer, aside from the occasional broken leg it's a high cardio but not over-work workout, generally very healthy until you get to heading in youth. There doesn't seem to be the concussion issue in the professional realm as with football but there are troubling signs to the point that YSA iirc is banning heading in U-14 or so play.
Football, the cardio benefits are similar to weight training in that it does improve but it is a training for short intense bursts which are generally inferior to a longer gentler workout per jogging/soccer, etc. The physical abuse of the body is virtually unparalleled, though I think many would be surprised at the abuse some other sports such as basketball take on the body, however it truly is a violent sport and little more needs to be said. I can not argue that in meaningful ways football meets the criteria of being good for one in the present, 10 yr, or 25+ yr future. It is a truly sobering thought for a sport I'd assume all here dearly love.
