"With training," Bowman said, "prepubescent children can significantly impact their heart and lung size, more substantially than they can after puberty. The larger the heart and lungs, the bigger the engine."
Yes, but what does Bowman base this on? If there is a study, it would be helpful to look at the original paper. If it is from urban legend (established thinking), then we should at least examine how true it is. (If it is from Bowman's personal experience with Phelps, then I am surprised that Ion accepts it. Bowman is dealing with an age group swimmer who is not in the 40-44 age bracket. ;) )
For instance, does the heart and lung size of a prepubescent child grow, *regardless* of training (just from the fact that the body is developing) ? In which case, there would need to be careful analysis to separate the growth due to puberty, versus the growth due to training. Perhaps this second factor is constant, regardless of age! (This is all sheer speculation. Comments from medical doctors would be appreciated. References to studies would be required.)
