摘要 The invention is training football having a plurality of perceptive elements, including tactile elements and visual elements. The tactile elements are positioned on an outer surface of the football in locations that correspond with locations that contact the hand of an individual when properly throwing a football. Accordingly, the tactile elements provide the individual with tactile information regarding proper hand positioning. The tactile elements may also provide the individual with visual cues regarding proper hand positioning. The visual elements are positioned on end portions of the football that are visible to the individual following a throw of the football, thereby providing the individual with feedback concerning the quality of each football throw.
