Firstly, this argument assumes consent on the part of the athlete. That’s somewhat unfair as most of these ‘harsh’ training camps are fairly secretive. We know this because even though the Karoyli’s were called out, no punishment could be made due to the difficulty in obtaining conclusive evidence. So it is unlikely athletes really know what they’re getting themselves into.  You can’t consent to abuse, not like this, we wouldn’t let you sign a contract to allow someone to starve you. Moreover, just because athletes would do anything to get gold, doesn’t mean we should let them. Some people would happily sell an organ for money, but we stop them doing that and morally are right to do so. Individuals don’t always know what’s best for them, that’s in-part, why the state exists.
