A sporting implement, such as a blade for a hockey stick, may include an outer layer, a core, and a recovery gel positioned between the core and the outer layer. The recovery gel can form a film, be compressible, shape recoverable, and pressurized to a predetermined pressure. The recovery gel can be configured to provide an integrated agent for filling cracks that appear during use of the blade and configured to absorb energy impacts between the outer layer and the core. When a crack appears, the predetermined pressure can be relieved inside the crack and fills a cavity formed by the crack to provide cohesion between the outer layer and the core to recreate a new material in the place of the crack. The recovery gel can be configured to help prevent cracks from propagating and actively heals potential damages by reducing stiffness loss caused by cracks.

A system comprising a flag stick and a ferrule for marking a golf hole, wherein the flag stick comprises a first end secured to a ferrule and a second end designed to be a clearly visible end with a flag, and where the ferrule comprises a head portion secured to the flag stick and a bottom portion designed for placement in a hole cup by a ferrule socket, where the head portion of the ferrule comprises a top surface with a flag stick hole for receiving a flag stick, where the flag stick and the ferrule are secured by means of fasteners, where the head portion of the ferrule comprises an elastic round piece, such that the ball can lie on a round piece and against the stick when the ball goes into the hole cup.

A chest pad that significantly reduces the occurrence of commotio cordis among athletes is disclosed. The chest pad may be utilized as a stand-alone chest protector intended to provide coverage primarily for the upper chest wall and the cardiac area. The chest pad may also be implanted into or utilized in traditional chest protectors that provide full coverage of the user's torso. The chest pad provides additional protection to the heart of the wearer such that impact in the heart area with a projectile is absorbed by the chest pad.

An exercise device includes a resilient compression member configured to resist a compressive force from a user, and a resilient tension member configured to couple to opposing sides of the compression member. The resilient tension member is also configured to form a first portion of a loop around the compression member and the user, and resist a tensile force from the user. The exercise device also includes an extension member configured to connect with opposing ends of the tension member to form a second portion of the loop around the compression member and the user.

A fencing training device including: a first part configured to be coupled to a fencing weapon; a second part configured to be coupled to a lower portion of a fencer's body; and a retractable connector disposed between the first and second parts. Also provided is a method of training a fencer to perform a lunge and a fencing training system for providing feedback to a fencer regarding improper technique.

Examples of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a body portion of a golf club head may include a top portion with a recess and a pocket inside the recess. A plate portion may be coupled to the body portion and may include a flat portion configured to fit inside the recess and a boss portion configured to fit inside the pocket. The boss portion may include a threaded port aligned with a through-port extending from a base portion of the pocket through to a sole portion of the body portion. A fastener may be inserted through a sole-end of the through-port and threadingly coupled to the threaded port to secure the plate portion to the body portion. Other examples may be described and claimed.

A golf club head with a hosel hole cover that helps improve the performance of the golf club head is disclosed. More specifically, the present invention relates to a golf club head having a hosel hole cover at a bottom portion of an interchangeable connection system that not only provides improved performance of the golf club head by strategically utilizing an existing opening to adjust the weighting of a golf club head, but it also improves the aerodynamics of the golf club head by eliminating undesirable recesses that could be detrimental to the aerodynamics of a golf club head.

A golf club head including a club head body comprising a back portion, a striking face, and an interior cavity formed between the back portion and the striking face, wherein the striking face comprises a front surface configured to strike a golf ball and a rear surface opposite the front surface, wherein the back portion is spaced from the rear surface, wherein an aperture is formed through the back portion, a damping element comprising an exterior portion located behind the back portion of the club head body, a damping portion located within the interior cavity of the golf club head, wherein the damping portion comprises a front surface abutting the rear surface of the striking face and a rear surface abutting the back portion of the club head body.

A method of exercising includes positioning a foot of a user onto a pedal of an exercise device. The pedal is pivotably connected to a pair of supports forming a triangular base and has a neutral position relative to a pivot axis of the device. The method includes applying a first force to the pedal to rotate the pedal about the pivot axis in a first direction, toward a first support. The method includes resisting movement of the pedal toward the first support with a resistance mechanism of the device. The method includes applying a second force to the pedal to rotate the pedal about the pivot axis in a second direction, opposite the first direction, toward a second support and away from the first support. The method includes resisting movement of the pedal toward the second support with the resistance mechanism of the device.
