With world records being shattered left and right at the World Swimming Championships in Rome, the sport's world governing body has confirmed a ban on the high-tech polyurethane body suits being used by most swimmers.

Executive director Cornel Marculescu said Tuesday the FINA Bureau upheld last week's decision by the general congress to put new regulations in place by May of 2010.  Male swimmers will be restricted to suits that go from the waist to the top of the knees, while women's suits cannot go past the shoulders or beyond the knees.

Materials used to make the suits will be restricted to "textiles," as defined by a scientific committee.  Standards for buoyancy, thickness and permeability of the suits will also be set.

FINA decided to make the changes after huge technological advances in the suits over the past 18 months have allowed swimmers to virtually rewrite the record book.
