***Never, WTF does that have to do with having an injury that could cause a growth plate issue?
In "normal" physical activites the body is able to compensate for the most fluid movements possible and naturally selects the path of least resistance. IE: while your running bases your ankle bends too much one way and your knees will compensate etc.
***Right, that must be why no one has ever twisted an ankle or broken a foot running bases. Oh wait, my brother once broke his foot running bases.
The very goal of weight training is to isolate muscle groups and work them to a level where break-down occurrs. This also puts great stress on the joints/tendons/cartlidge/fluids etc directly involved in those muscle groups as evidenced by so many posts about this and that hurting after performing exercise x. Me being a logical person, it makes "sense" to me that putting a young growing body under those stresses isn't practical and possibly not safe.
***Weight lifting is generally predictable. You cannot predict how you're kid will land when tackled, or where a ball is going to be hit (possibly causing a collision with another kid), or if a basketball shot is going to end up coming down and being stepped on, thus turning or breaking an ankle...I could go on and on. Lifting is generally done in a controlled, supervised environment where injuries are much less likely to occur.
