The general belief is that epiphysis factures, particularly in the wrist and spine, can occur from weight lifting and the stress/strain of overload, but even the American Academy of Pediatrics is on-board with kids lifting properly. Solid form (obviously, but often neglected or simply coached poorly) and no Rep-Max work to failure, particularly with prepubecent lifters.
The AAP is in favor of kids lifting moderate weights in a moderate rep range, and against kids competing in powerlifting or Oly lifting which, by definition, tests 1RM at meets. Once a kid reaches physical maturity (post-puberty), the rules of lifting change and the body can tolerate more stress with relatively less risk.
I'd say yes and no. Progressive overload (as with weight training) is a "different kind of taxing", compared to gymnastic-type work. But I'd be interested in the injury stats (short and long-term) comparing youth gymnastics to youth strength training.
