If I get the jist of that sturdy... claiming that the 1/4 and 1/2 squats greatly improved 28-college students vertical jump and sprint performance over 16 weeks, then I'd have to agree, but that doesn't mean that we should all be doing 1/4 & 1/2 squats in lieu of full depth.

If someone is serious about total body health, be careful of training the body for specific exercises or following the training regimens of professional athletes. If I were training for a race or something, I'd probably cut out the full depth squats (and a bunch of other things), but most of us are not training for an event/race. Nature abhors not only vacuums, but also specialists.
