Abstract: Scoring equipment particularly adaptable to a sword combat sport, includes a limb target and a helmet. The limb target has a base configured to be worn by a user at a location near a joint of the user's limb. A lever is pivotally mounted on the base and extends to a lever terminal end. The lever terminal end is fastened to the user on a side of the user's joint opposite the base. A locking mechanism is connected between the base and the lever. The locking mechanism has a set condition in which articulation of the user's joint is unencumbered by the scoring equipment. The locking mechanism also has a tripped condition in which the locking mechanism restricts the rotation of the lever relative to the base and thereby restricts the articulation of the user's joint. The locking mechanism is responsive to a force applied to the locking mechanism to place the locking mechanism in the tripped condition from the set condition.

Abstract: A low-rebound, impact-deformable footbag includes plural panels having peripheral edges which are connected together to define an impact-deformable, semi-collapsible chamber which permits the footbag to assume an arbitrarily-changing, random shape in response to an externally-applied deformation force, such as kicking. The footbag includes at least one panel, a portion of which is formed from an apertured material for providing a view internally of the chamber. Plural lightweight, impact-damping filler members are disposed in the chamber, some of which being viewable through the apertured material. Such filler members are positioned within the chamber for interacting with other such filler members for damping such applied deformation force.
