I have not found much information on this. I guess hanging out on the Charlie Francis forum or Parissi Speed forum would be educational. The links below are interesting and (if accurate) offer some insight into this issue.
This is an intriguing topic and it seems to hover around the point that people need to be stronger to move faster...but moving things faster (Olifts, Plyo's) offer great benefit.
As to the additional joint loading...not sure about that. The power variants of the OL's seem a good option here. Interesting stuff and on a personal level I really like the training involved with being a sprinter. I enjoy that speed, power and feeling of acceleration.
