Any workout system can be misused particularly with growing young athletes.
Great care needs to be taken by instructors to keep kids from moving into workouts and exercises that might be dangerous.
As a fitness nut, my enthusiasm stems from the fact that kids are working out and they like it!
That said, your points are well taken.
Whether it's Crossfit or any other regime...great care needs to be taken by instructors so as to prevent young bodies from moving into dangerous territory re: heavy lifting, etc.
The move of implementing crossfit and the physical needs of it are getting so popular that many are trying to use it, whether it is needed or not, as a technique for success when it is not designed for the common person. And youth are not ready for it so their program would have to be individualized by a physician based upon capacity. It isn’t a one size fits all program that the school systems you mentioned aer throwing in there without considering the side effects. They did it before years ago when a number of systems decided football was too violent. So they replaced it with rugby! No need to go any furthrr with that one.
