Abstract
A throwing exercise apparatus using a sphere with an internal polar passageway to deliver end portions a non-elastic band of which one end portion circumscribes the outer surface of the sphere and extends to the other end portion where they are joined together by a fastener. The band is then joined by an elastic member to an anchor so that in use there is established a path of elastic resistance along a tangential line formed by the wrapped part of a strap mid portion in response to an applied force comprising both translation and rotational motions of the sphere. The motions of the sphere bring about rotation of the internal polar passage in an end-over-end fashion.
Claims10
A throwing exercise apparatus including said combination of:
- a sphere having an exterior spherical surface containing first and second diametrically opposed access sites to an internal polar passage;
- an elongated anchor strap having a first strap mid portion traversing said internal polar passage and strap end portions interconnected by a fastener at said first access site to said internal polar passage, said elongated anchor strap having a second strap mid portion wrapped against a substantial part of said exterior spherical surface of said sphere between said second access site and said first access site to establish a path of elastic resistance along a tangential line formed by the wrapped part of said second strap mid portion in response to an applied force comprising both translation and rotational motions of the sphere, said internal polar passage rotating end-over-end fashion by said rotational motion;
- and
- an elastic band anchored to a static structure at one end and joined to said strap end portions interconnected by a fastener.
