A posterior knee guard is coupled to a shin guard which includes a front shell, padding, and an elastic mounting strap. The posterior knee guard includes a hard outer layer and an resilient inner pad. The inner pad has a strap channel extending laterally therethrough which is configured to receive the mounting strap of the shin guard. The outer layer may be overlaid with a strong covering material. The outer layer has a vertical column of horizontally extending guard strips. The guard strips are separated from each other to form a space between adjacent guard strips.

A hand-held hand exercise apparatus capable of being used for stroke rehabilitation can include a foam body, a knotted strip of elastic material, and structure embedded in the body. The body can be configured to be held and compressed by a user's hand. The knotted strip can form inner and outer loops. The embedded structure can extend through the inner loop to at least partially connect the knotted strip to the body. The outer loop can be outside of the body. A user holding the body can have their finger extend through the outer loop to restrict the body from being dropped.

A golf mat has a high-density polyurethane viscoelastic foam removably placed in a cutout formed in a base. A hitting section is attached to an upper surface of the foam so that impacts of golf swing hitting the mat is absorbed by the foam. The foam may be placed in a protective bag to protect the foam from chipping and fraying. The hitting area is made with nylon having thermochromic pigments so that the pigments change color temporarily due to increased temperature from friction caused by impact and swipe of a golf clubhead on the hitting section when the golf clubhead hits the hitting section. The mat has a standing section with vertical lines and horizontal lines for the alignment of the golfer's feet. Moreover, the mat has a first set and a second set of on-the-mat-swing-path lines to compare the direction of temporary heat signature left by a divot.

An iron-type golf club head includes a body having a wall extending about an opening, a faceplate coupled to the body across the opening, and a fill material. The wall defines a first set of apertures and a second aperture, and includes an outer peripheral surface, a sole and a rear wall portion extending from the heel to the toe. The wall and the faceplate define a rearward-facing back cavity. The sole, the rear wall portion and the faceplate define a lower cavity that is continuous with the back cavity. The first set of apertures and the second aperture extend through the wall from the peripheral outer surface to, and are continuous with, the lower cavity. The first set of apertures and the second aperture extend about first and second planes, respectively. The fill material substantially fills the lower cavity and the first set of apertures and the second aperture.

A unique and innovative shaft for a golf club significantly enhances stability and shock absorption during golf swings. Taking advantage of the excellent flexibility, surface strength and shock absorption of a bamboo pole, the shaft is designed following the physical structure of the bamboo pole, thus helping facilitate vibration damping and absorption, stability during golf swings, supersymmetry and balance. The shaft comprises a plurality of connectors, each of which is a solid material and connects a plurality of links into an elongated member of the present invention. The plurality of connectors may be attached to the inside wall of the elongated member when designed as a tube. By varying the positions of connectors across the elongated member, the bamboo-inspired shaft can be configured to feature desired levels of flexibility and corrective/reversible torsion at one or more points on the shaft, thus help any golf player achieve substantial performance improvements.

The present invention is directed to an apparatus for throwing and catching a football by a user of the apparatus. The apparatus includes a football having a connector, such as a loop, attached to one end of the football, specifically the point of the football; an elastic cord having connectors at opposite ends, with one connector configured to attach to the connector on the football and the opposite connector configured to attach to a stationary object or anchor to anchor the apparatus during use, and wherein each connector attached to the elastic cord is configured to swivel such that the opposite ends of each connector can freely rotate relative to each other to allow the football to rotate relative to the elastic cord and to allow the elastic cord to rotate relative to the anchor.

A golf club head including a striking face, a periphery portion surrounding and extending rearwards from 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, a support arm spaced from the rear surface of the striking face, the support arm extending from the periphery portion, wherein the support arm is affixed to the periphery portion at two distinct locations, a damping element residing between the support arm and the rear surface of the striking face, wherein the damping element comprises a front surface in contact with the rear surface of the striking face and a rear surface in contact with the support arm, wherein the support arm extends substantially parallel a horizontal axis.

A system for analyzing a putting motion includes: mat markers attached to a mat on which a ball is placed; a putter marker attached to a putter for applying an impact to the ball; a mat having a color contrasting with colors of the mat markers, the putter marker and the ball; a camera for photographing the mat markers, the ball, and the putter marker; a mat detection unit for detecting a position of the mat from an image photographed by the camera; an object detection unit for detecting positions of the putter and the ball in real time; a ball calculation unit for calculating a speed and a moving direction of the ball based on the detected ball; and a pointer calculation unit for calculating a pointer position for a menu selection function necessary for a simulator operation by using coordinates of the detected putter.

Attachments for isokinetic dynamometers and methods of use thereof are provided for use with subjects having limb impairments. An example dynamometer attachment for use with a subject having an impaired limb includes a frame that has fixed thereto a padded limb support, where the padded limb support is configured to secure an impaired limb of the subject. The padded limb support includes a securing mechanism for securing the impaired limb relative to the frame, and the frame is connected to the dynamometer lever arm via an intermediate connector assembly. The connector assembly permits translation of the padded limb support in at least two dimensions relative to the lever arm prior to securing the frame fixedly in place. The translation adjustability of the attachment facilitates the alignment of the dynamometer attachment to the limb or partial limb of the subject without requiring movement of the subject.
