There is no scientific evidence involved that i have found after much research. There are too many variables involved to conclude the experiment. Keep in mind, growth plate closure theory is just a theory, not a scientific law.
To the issue of weightlifting before growth spurts, i myself am a prime example. I started weight lifting at 12 and could match my body weight in squat by 13. Around the same time, i under went 3 major growth spurts, now being 23cm taller than when i started, and 20-23 kilos heavier, but i am still classified as a skinny person. Currently i am 176cm and 62kg at 14 year old.
No doubt weightlifting with incorrect technique or excessive training regime can lead to overuse injury, but the positive effects are greater. Recently i have had a wrist overuse tendon injury. After having an Xray scan, my ulnar has not yet hardened and fused into one bone, proof that i am still growing. About to reach the same height as my father, definitely taller than my mother.
I definitely recommend hitting up the gym, but remember to not train too excessivly (i mean 4 times a week of 2hours which is too much for my own good). Train hard!

i started when i was 13 i was 6 foot 2 and 82 kilos i am now 15 and 88 kilos and i am close to 6 foot 4. i did bench press squat (without weight) arm curls triceps kickbacks. i don't think it stunts your growth. don't do any exercise that evolves over head movement like shoulder press because that will stunt your growth

dude i am six feet six at 15 and have been lifting weights from 14. It does not stunt growth.

Here are 52 articles that will prove weight training is safe. The one stipulation being that you are under supervision but almost all weight training injuries are due to either bad lifting machanics or acute injury. Both of which can be corrected by a fitness professional. So it is safe if you are taught correctly how to do it and have a competent person to spot you. If you have any papers showing it will stunt your growth post it I want to include it in my paper.

Sorry, I know this is an old post, but from personal experience I can say that a lot of information out there is misguided and wrong. I started weightlifting at 13, and at the time I was 5'5''. I have lifted to a plan with perfect form and (almost) perfect nutrition for three years and, although i have seen a large increase in muscle mass, i have not gained an inch in height. The way I understand it, an increase in muscle mass causes an increase in testosterone production, which in turn closes the growth plates, preventing any increase in height. I would leave the weight training until you are at least sixteen, maybe even eighteen.
