The conclusion of this study
(http://www.medscape.com/viewarticle/584086?src=mp&spon=8&uac=39169AZ) was "The
results of this study relate larger knee joint loads to poor hamstring
flexibility, greater body weight, greater weekly mileage, and greater muscular
strength. Most of these risk factors could potentially be modified to reduce
joint loads to lower the risk of injury."
