Exemplary embodiments of the present disclosure are directed to systems, methods, and computer-readable media configured to autonomously track a round of golf and/or autonomously generate personalized recommendations for a user before, during, or after a round of golf. The systems and methods can utilize course data, environmental data, user data, and/or equipment data in conjunctions with one or more machine learning algorithms to autonomously generate the personalized recommendations.

A thumb brace comprising a glove having a thumb portion disposed between a palm side and a back side and comprising a first attachment region positioned adjacent a base of the thumb portion and a second attachment region positioned on the back side of the glove; a first elastic strap whereby the first strap extends a distal end of a thumb metacarpal bone of a user of the brace; a second elastic strap having a first end attached to the palm side of the glove and the second end releasably attached to the second attachment region, whereby the second strap reduces a proximal end of a thumb metacarpal bone of a user of the brace; and a pad attached to the glove such that the pad cushions a CMC joint of the user of the brace from impact.

Embodiments of golf club heads comprising a club face with a variable thickness profile to adjust stiffness and characteristic time (CT) are described herein. The variable thickness profile comprises strategically positioned thickened and thinned regions. In many embodiments, variable thickness profile can taper from a thickened region to a thinned region. The thickened region can comprise a maximum thickness of the club face, and the thinned region can comprise a minimum thickness of the club face. The variable thickness profiles described in this disclosure increase stiffness in a high toe area of the club face and decrease stiffness in a heel area of the club face.

A golf club has a first shaft coupled to a club head, a second shaft configured to slidably engage a portion of the first shaft, a grip coupled to the second shaft, and an adjustable length shaft assembly received by the second shaft and configured to allow a portion of the first shaft to slide in relation to the second shaft in a first configuration, and to restrict a portion of the first shaft from sliding in relation to the second shaft in a second configuration. The grip is restricted from rotation about the first shaft or the second shaft as the first shaft slides in relation to the second shaft.

A system and method for analyzing the swing motion of sporting equipment, for example, a golf club, including at least one or more inertial acceleration sensors, one or more gyrometric sensors, a data acquiring unit, a core micro-controller, and a Bluetooth radio. The motion detecting unit detects at least one motion of the swing. Particularly, the sensors and data acquiring unit calculates swing information using the acquired detection data to match a user's swing motion to optimized equipment. Particularly, the data acquiring unit acquires detection data from the sensor(s) and forwards such data to a computing device or server having stored information that matches the swing motion to an optimized swing device.

A swing analysis system is disclosed herein. The swing analysis system includes at least one user input device; a motion capture system comprising at least one motion capture device configured to detect the motion of at least one of: (i) one or more body segments of a subject, (ii) a head and/or face of the subject, (iii) a hand and/or fingers of the subject, and (iv) an object being manipulated by the subject, and generate output data; and at least one data processing device operatively coupled to the user input device and the motion capture system, the at least one data processing device being programmed to perform autodetection for the movement of the subject that is selected by the user by inputting the output data from the motion capture system into a trained neural network so that the movement being performed by the subject is able to be automatically determined.

A system and method for generating at least one golf ball recommendation for a particular golfer is disclosed herein. In one aspect, the present disclosure is directed to using a machine-learning model configured to generate at least one golf ball recommendation based on a golfer's swing.

Disclosed herein is a driver-type golf club head including a metallic front body portion having a first front body portion and a second front body portion, both of which are metallic, and portions of each form a strike plate opening that receives a strike plate.

A wrist strengthening device includes a first handle, a second handle, and a tightening component in the form of a clamp configured to tighten around at least a portion of the first handle and at least a portion of the second handle. A sleeve is positioned radially between 1) the tightening component and 2) the at least a portion of the first handle and the at least a portion of the second handle. An interior member in the form of a rod extends from at or near an axial end of the first handle to at or near an axial end of the second handle. The device further includes a first end cap at the axial end of the first handle and a second cap at the axial end of the second handle. The wrist strengthening device is devoid of any spring component.

A golf club head comprising two components, wherein the first component comprise a ball striking surface, a striking face return, and a sole extension with a rear mass. And wherein the second component comprises a lower density material, comprising part of the crown and part of the sole. The first component comprises a majority of the mass of the golf club head, having a rear mass comprising 20% to 35% of the mass of the golf club head.
