The present invention is directed to a garment for assisting a user to instantaneously visualize and remember a coordinated movement of body segments at the moment before and/or during the task. The coordinated movement can be related to any physical task such as sports, therapy, aerobics, dance, etc. The garment according to the present invention comprises an arrangement of arrows in or on a fabric of the garment, wherein the position of the arrows relative to body segments and the direction of the arrows indicates the direction in which the related body segment should be moved and/or aligned.

Hinges for multipurpose golf training aids, and more particularly, long-wearing, durable low-profile hinges for multipurpose golf training aids, and methods for manufacturing such hinges are disclosed.

A small compact golf swing alignment aid that lies flat on the ground and can readily be disassembled and placed in a small carrying case that can be carried in the side pocket of any golf bag is described. It requires no attachments to the body nor any parts extending upward from the ground. It assembles flat on the ground with side rods e.g. tubes, that project rearwardly on either side of the user's feet to facilitate foot spacing and foot and body alignment, two front rods e.g. tubes, each of which releasably couples to the front end of one of the side rods, tubes, and are releasably joined endwise to each other through the two opposite side couplings of a three way coupler to form a straight target alignment rod to facilitate proper foot spacing and provide target alignment, and a centrally located vertically forwardly projecting tube releasably connected to the front coupler of said three way coupler to serve as a ball positioning tube.

Apparatus, systems, and methods are provided for measuring and analyzing movements of a body and for communicating information related to such body movements over a network. In certain embodiments, a system gathers biometric and biomechanical data relating to positions, orientations, and movements of various body parts of a user performed during sports activities, physical rehabilitation, or military or law enforcement activities. The biometric and biomechanical data can be communicated to a local and/or remote interface, which uses digital performance assessment tools to provide a performance evaluation to the user. The performance evaluation may include a graphical representation (e.g., a video), statistical information, and/or a comparison to another user and/or instructor. In some embodiments, the biometric and biomechanical data is communicated wirelessly to one or more devices including a processor, display, and/or data storage medium for further analysis, archiving, and data mining. In some embodiments, the device includes a cellular telephone.

The invention relates to a method for the analysis of movement of a piece of sports equipment of a type of ball sport, in particular a racket, preferably a golf club, or a ball, preferably a golf ball, wherein a first virtual trajectory model is reproduced in a display device in a way that said first virtual trajectory model is displayed as a first line on the display device in superimposition with at least one, in particular in reality, visible section of the environment, particularly when a field of view is directed on the at least one section of the environment which is visible in reality.

An alignment rod includes a first rod and a second rod movably connected to each other, and a first connecting rod and a second connecting rod connecting the first rod and the second rod. The first rod and the second rod substantially overlap each other in a collapsed configuration, and the first rod and the second rod are spaced apart from each other in an expanded configuration.

A golf putting training device for improving a putting stroke of a user includes a base that is positionable on a surface. A pair of posts is coupled by lower ends to the base. Each post is positioned proximate to a respective opposed side of the base so that the posts define a reference plane that is perpendicular to the base. A guide unit is engaged to and extends from the base in a guide plane that is parallel to the reference plane guides a shaft of a putter during a putting stroke. A constriction unit that is engaged to the posts and selectively positionable in abutment to outer faces of knees of a user prevents outward motion of the knees during the putting stroke. A stance governing unit that is engaged to upper ends of the posts templates a posture of the user during the putting stroke.

A golf training apparatus is provided for placement in-between a golfer's feet while the golfer is swinging a club and hitting golf balls to provide both resistance and feedback on the application of ideal foot pressure and ideal lower body force in ideal directions during their golf swing. The apparatus is fabricated from two boards that are adjustably connected and slide along two slots to create different board length dimensions.

A golf practice device is disclosed to derive a proper stance and swing form of a golf club. The device to be installed on a shaft of a golf club with a club head, comprises a fixing part to be installed on the shaft and including a bearing part formed at a part thereof, and a shaft part to be fitted in the bearing part. In a state where a longitudinal direction of the shaft is horizontalized and a toe side of the club head is located on a ground side, the fixing part is installed at a center of gravity position of the entire golf club, on the shaft, and one end in an opposite side of the bearing part in the longitudinal direction, of the shaft part faces a vertical direction with respect to the longitudinal direction of the shaft to point a core of the golf club.

A golf ball address training method including steps of providing a club set and a ground mat having a lateral line, selecting a highest loft club, orienting the lateral line up-range, and aligning an up-range foot with the lateral line, alternatively selecting a lowest loft club, orienting the lateral line down-range, and aligning a down-range foot with the lateral line, alternatively selecting a lowest high loft club, orienting the lateral line up-range, and placing the up-range foot a greatest distance up-range, alternatively selecting a highest low loft club, orienting the lateral line down-range, and placing the down-range foot a greatest distance down-range, alternatively selecting low or high loft intermediate clubs, correspondingly orienting the lateral line down-range or up-range, and correspondingly intermediately placing the down-range and up-range feet.
