ABSTRACT:
A volleyball training and monitoring apparatus comprising a base and an upright support member connected to the base and extending upward from the base. The upright support member has an inner member slideably secured therein and extendably adjustable by a handle secured to a notched element operably engaged to a gear housing a sprocket engaged with the inner upright member. A volleyball is supported and positioned by an arm secured to a cam and cam follower assembly mounted on the upright member which provides instant feedback to the user if a correct hit or incorrect hit of the volleyball is made by allowing rotation of the arm if a correct hit is made, while limiting arm movement if an incorrect hit is made. An angle adjustment apparatus is secured to the upright support member and to the arm. The angle adjustment apparatus includes a positioning plate having angle markings thereon and an angle locating disk including a plurality of spaced detents for positioning and alignment of the disk with the angle marking on the positioning plate allowing control of the angle at which the arm and volleyball are positioned.
