An easy-to-disassemble connector and sport training equipment has a first connecting assembly and a second connecting assembly that can be separated from or connected to each other. The first connecting assembly is connected to a rope, and the second connecting assembly is connected to a ball. The first connecting assembly has a first rotating-embedded unit, and the second connecting assembly has a second rotating-embedded unit connected to the first rotating-embedded unit. When the first rotating-embedded unit and the second rotating-embedded unit are connected to each other, it is convenient for the user to hold the rope to assist in sport trainings. When the first rotating-embedded unit and the second rotating-embedded unit are separated from each other, the first connecting assembly and the second connecting assembly are separated from each other and the ball can be used independently.

A basketball shot determination system for use with a basket and a portable electronic device including a data acquisition device, a processing unit, a memory and an output device, the system includes a basketball, at least one sensor carried by the basketball, and a non-transient computer-readable medium. The medium contains code to direct the processor to obtain at least one attribute of a shot of the basketball towards the basket from the data acquisition device. The at least one attribute is sensed by the sensor or derived from signal output by the sensor. The medium contains code to direct the processor to determine whether the shot is a made basket by comparing the at least one attribute of the shot to one or more predetermined signature characteristics of a made basket, and to present output to a person based on the determination of whether the shot is a made basket.

A sports training device for pitching and throwing has a ball core and a cover material. The core member defines a passageway extending through the ball core and also defines an anchor recess into a surface of the ball core. The anchor recess is aligned with and communicates with the passageway. A cloth member has a geometric shape with at least one corner and defining an attachment portion and a body portion extending away from the attachment portion. The attachment portion extends through the passageway and is attached to an anchor member sized to be received in the anchor recess. A cover material is installed over the ball core with the body portion of the cloth member extending through a cover opening and out from the ball core.
