I think you're exaggerating in saying they got HUGE, you can't get huge from swimming, impossible. You can build a strong and muscular physique, but huge muscle? That goes against the science of how muscle is built.
The only downside of swimming is the chlorinated pools. A friend of mine at school swam at a national level, he swam for 2 hours every morning and the chlorine caused him to go bald.
