Fine, fine. But we're beyond that point now. Old sumo wrestlers all have injuries. Old keirin racers don't. Pushing against some limits leads to injury whereas pushing against others (like racecraft) doesn't.
I do not accept that all sports and all limits within any given sport have equal risk of chronic or lingering injury. Therefore there is an element of choice for each athlete, which sport and which direction to push in and on which scale. Raw power? Agility? Racecraft?
I submit to you that ski racers have significantly more development direction choices than sumo wrestlers, bodybuilders or power lifters do.
Bowling or golf vs boxing or skiing yes the level of injury risk & severity are different.
And I submit not all old cyclists are competition related injury free. You can get some pretty serious crashes - even in a ITT
I submit pushing against others is pushing against limits. Its natural and and to me a good thing. It gets bad with bad preparation, bad technique & bad advice.
Specific to ski racing it would be helpful if there was data collected on
- what type of injuries
- what race discipline
- etc
and by age groups, at what age, level of capability & sex
Then perhaps then develop more practical guidelines, to not limit high performance, but prevent or minimize injuries etc using better course setting, equipment stds that are sensible, sports medicine and science based coaching.
