<p>A club or bat, e.g. baseball bat 10, includes an internal passage within the handle 11 and/or body 12, and a shuttle body 17 arranged to move within the passage when the bat is swung. The passage may be substantially straight, and the shuttle body 17 fits closely with the passage in order that the shuttle only moves when the bat is swung. Stop means 14, 16 may be provided at the ends of the passage against which the shuttle impacts in order to produce a tactile, visual, and/or audible effect, e.g. a sound similar to the noise of the bat striking a ball. A sound may alternatively be produced using electrical means (not shown), and the bat or club may alternatively comprise a cricket bat, golf club, hockey stick or sports racket.</p> |
