> "but hiit also causes a lot of damage in a lot of ways"

Please do explain this.

Technically weight lifting (muscle hypertrophy) also causes "damage" but in a controlled an beneficial way.

I really think you're being pedantic to the point of detriment. Runner's knee is a very well known condition in, wait for it, runners!

I think you're wrong. I've been running with good form, proper nutrition, and rest, for over 40 years, averaging 20-30 miles a week, and have absolutely zero knee issues.

I think you're running a risk here of turning more people off from running, and doing more harm than good, by warning people of a risk that while possible, is unlikely to affect them.

Generally these types of degenerative conditions have other underlying conditions driving them, and are not simply the result of running. We are born to move.

Seems to me hiit is a way to avoid these overuse injuries.

I think runner knee was a bad example.

Sprint running is more sensitive to form in order to avoid injuries, especially in older adults.

I would guess they mean hiit can traumatize e.g. joints or cardiovascular system, especially for the elderly.

[jr3592]

Most people don't understand how important, even vital, proper rest is. Injuries are almost always the result of overuse and/or insufficient rest.

HIIT itself is not dangerous, or even bad for you, if you spend the time to learn about it and how to incorporate into your life safely. If you're out of shape, and don't train regularly, go out and try HIIT you're going to have a bad time.

Could you provide some resources for learning?

yeah this is what I meant - as we get older we're supposed to move slower, and spend more time working on mobility and strength (moderate strength building, walking, and other movements like taichi and equivalent)
