...my father and I both have the "superbaby" mutation. severe myostatin deficiency. My father's bones are near unbreakable and he became locally famous after lifting a minivan.
His strength is comparable to between 3 and 5 normal men and his strength peaked at about the age of 40. His brother Joseph is suspected of having the mutation as well.
Our muscles grow at incredible rates, but don't grow much larger. The muscle fibre packs tightly- so tightly in fact that they tear under their own strength, causing us to suddenly collapse for no apparrent reason with massive muscle tears.
We have body fat of >1% and abnormal muscle definition.
...my father once jokingly held a washing machine in his outstretched arm, obviously considerably more than this 10 lb from the 4 yr old.
I don't know what we are really capable of, but I can tell you from experience that myostatin deficiency is not always a benefit. The constant pain from muscle growth and the inevitable tears that follow are horrendous and it is suspected that the huge muscle mass presses on our blood vessels, forcing blood pressure up and making our hearts less effective.[/QUOTE]
That last sentence caught my attention. Its funny that edxercise which is good for the heart can actually hurt it. I hope it won't be a problem for someone whose natty.
