From comparing his numbers he seems to have slightly early onset puberty but followed average curve of growth. So from the article nothing really sticks out aside. From early growth. With just the article we can't really tell if his bone growth happened in line with expectations and just earlier or not.

he did have early cessation of growth. Compared to his parents he really ended up on the shorter side. Plus what I'm more worried about is the fact that his bone age advanced DESPITE no biological maturation as it is stated in the article. which could be due to the fact he had pretty high test and estradiol levels (740 test with 800 being the highest normal level for his age). Could building muscle through strength training induce in extreme cases such as this one an effect of acceleration when it comes to puberty??Could it increase androgen production and in a way force the body to go through puberty much faster? that's my question. As I said I don't claim to be a doctor and could very well be wrong.

That looks far more like a case of early puberty, than exercise induced issues. The premature growth plate fusion mentioned in the references was due to traumatic injuries rather than a global effect. Also, lets not ignore that he's a 6ft 13 year old, which as stated is _tall_ for his age.

Sure he was tall for his age but not tall for his parents. Also there was no mention of injury? if he had indeed broken his growth plates km sure it would have said something like that. Did you read the entire article? Or did i miss something? This was discovered on a routine exam and he had no injuries.

I'm referring to the references used by the article you've linked. The source your article uses to link weight training to early growth plate closure refers to this happening in the case of traumatic injuries, rather than a global phenomenon. This is a risk in all paediatric traumas, and is why things like expanding prosthetics exist.

In regards to his parents' heights, there is always likely to be an element of reversion towards the mean, plus early/precocious puberty causes a reduced height anyway.

yes I understand. however I'm taking about this specific case here. It is well established that lifting does not stunt growth when it is done safely. However could it be the case that in some individuals or in some cases of very early and heavy lifting it could have effects as these. from the article :"Although current research findings indicate an acceptable safety of age-appropriate resistance training in children and adolescents, few isolated cases of sport-related growth disturbances have been described. This case highlights the rare occurrence of premature growth cessation as a possible consequence of excessive resistance training in apparently healthy athletic boy with no endocrine dysfunction. In this patient, complete epiphyseal growth plate fusion was observed (except for distal radius) at age 13, while no biological maturation has been completed"

You don't need to quote the articles conclusion at me.

1. This is a case report, not a comprehensive body of work/research
2. There are more likely explanations for his height
3. We don't even know what height he'll end up as they've only reported on forearm growth plates.

Look, whatever height you are, just come to accept it. There is precious little you can change about it now, and being fit/strong is only going to be a benefit in your future life.
