The first (1991) of<br> these<br> examined the kinetics of sudden&nbsp; 30 or 60 degrees<br> turns during<br> walking at preferred speed. The second study (1999)<br> looked at<br> some kinematic factors during 20, 40 and 60 degree<br> turns and<br> compared them when subjects had short or long notice<br> of the turn.<br> Hase and Stein have also described the strategies used<br> to make<br> sudden 180deg during walking and there are a few<br> studies<br> comparing the kinetics of sudden turns to those of<br> initiating and<br> stopping walking.<br> <br> Get the Book: Human Walking by Vern Inman<br> <br> An entire chapter is devoted to Kinematics and is very<br> help full.<br> <br> Taper dans biomed ou medline les auteurs suivant :<br> Patla<br> Grasso R<br> Glasauer S<br> Solomon D<br> <br> Look in PubMed at A.Patla and M.
