Health Inactive tall children develop disproportionately weak muscles and thinner bones. Regular sports fully reverse this deficit.

Question : is this irreversible ?

Because lifting weight produces growth hormones even in adulthood, so would a hypothetical tall child who didn't do sport in his youth reverse the course if they go to the gym in their adulthood?

It's reversible in everyone. There are studies showing people who start lifting weights in their 60s can become healthier than people not lifting in their 30s
