title: Variable resistance training using elastic bands to enhance lower extremity strengthening.
abstract: Strengthening of the quadriceps is a central tenet of lower extremity rehabilitation, particularly after knee surgery. Quadriceps deficits after various knee procedures are well-documented. One method common to strength and conditioning circles is variable resistance training (VRT). VRT involves the use of heavy chains and elastic bands to facilitate gains in strength and power. Most of the application in strength training however has been on healthy, trained athletes. Sports physical therapists may use elastic bands for VRT to augment strength gains for the recovering athlete. The purpose of this manuscript is to provide a clinical suggestion for the use of VRT in athletic rehabilitation.
