A ball toy having a solid, resiliently flexible body is disclosed. The body is penetrated by a bore, wherein bearing means are mounted, defining a rotational axis of the body therein. The bore has a bore closure at each end, mechanical connection means connecting each closure to the bearing means. The body is able to spin on said axis relative to the closures, when the closures are held in a pinching manner by a user. The body is made of a thermoplastic rubber of selected hardness properties, giving it excellent bouncing performance, with unpredictability of bouncing direction resulting from the spinning of the body.

A toy ball which emits sounds as it is rolled and including a ball body and a plurality of mechanically-operated sound producing tubes carried within the ball body, each sound producing tube including a sound-producing device which moves by the force of gravity, and each sound producing tube lying along a longitudinal axis, in which the axes are transverse to one another so that the sound producing devices emit sound when the ball is rolled along various axes. The ends of the sound-producing tubes are held by sleeves that are molded as integral parts of the ball body.

An American-style football may include a prolate spheroidal shaped bladder having a longitudinal axis, an outermost layer about the bladder, a lacing surface featuring a series of parallel projections from an exterior of the outermost layer and an intermediate sandwiched between the bladder and the outermost layer, wherein the intermediate layer is configured to decrease a MOI of the football.

Provided is an analysis apparatus for analyzing a behavior of a ball that has a center of gravity and in which an acceleration sensor is installed at a position shifted from the center of gravity by a predetermined shift amount, the analysis apparatus including a control unit configured to derive a centrifugal acceleration that is applied to the acceleration sensor, based on acceleration data that is output by the acceleration sensor, and derive at least one of a direction of a rotation axis and a rotation speed of a spin of the ball, based on the predetermined shift amount and the centrifugal acceleration.

A practice ball with an off-axis weight distribution allows sportspeople to practice their ball catching, passing and other skills using a ball that flies through the air with a wobbly trajectory.

A luminous safety ball including an inner glowing body and a foam sphere covering the inner glowing body is provided. The inner glowing body is not a perfect sphere, the foam sphere has a non-uniform thickness, and light emitted by the inner glowing body passes through the foam sphere and permeates through a surface of the foam sphere to form light with different brightness thereon.

A lightweight spherical baseball like training ball has a hollow core adhered to a stitched white colored synthetic leather cover with a thin layer of adhesive. The lightweight ball has raised seams and measures in circumference similar to the ball circumference size mandated by Major League Baseball rules whereby the ball is suitable for baseball and softball training and playing variations of the game of baseball or softball in confined areas.
