Abstract: An extended port arrangement for a multi-chambered sequential compression sleeve where a port extends through an outer large pressure chamber and in communication with an inner pressure chamber. The extended port consists of an inner bushing sealable with the sheet defining the inner chamber. The port has a housing which extends through an outer sheet and mates with the inner bushing and is in fluid communication therewith.

Abstract: A blocking sled designed for the development and practice of football pass blocking techniques having a base with an elongated arm pivoted thereto. Operatively connected between the arm and the base is a piston arrangement in which the piston rod supports a compressible spring so that movement of the arm towards a 90.degree. angle with respect to the base is resisted. In use, a player generally stands on either side of the arm and strikes with the palms of his hands an impacting surface integral with the arm, thus causing the arm to move about its pivot through a 90.degree. angle with respect to the base.
