The present invention provides a putting guide capable of correcting a posture when putting, checking a contact angle between a putter and a golf ball, correcting a posture of an exerciser during a putting practice, and checking a focusing point that the exerciser watches. The putting guide for putting practice includes a hitting part, a rod part connected to the hitting part, and a front part formed on an end of the rod part.

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.

A golf club comprising a golf club head having a face wall, an inertial motion unit (IMU) positioned within the body, and a transceiver in communication with the IMU, a shaft attached to the golf club head, and a grip attached to the shaft is disclosed herein. The IMU identifies an impact location with a golf ball.

The present disclosure relates to intersectional impact training tools. Aspects of the present disclosure provide attachable intersection impact training tools, which can be attached to sport implements to enable the user to observe and practice intersectional impact. In an exemplary implementation, the training tool can include clips/clamp, which can be fixed with a sport implement, a stiff wire that can hold a ball at centre surface away of the sport implement. The training tool can be attached with sport implement so as to enable a player to practice a particular punching action/technique for multiple sports, for example, forward and backward intersectional movement or forward and forward inline movement, or side movement. The proposed training tools use universal biomechanical techniques that resolve health issues and provide positive results in sports and physiotherapy.

An artificial turf for golf mimics visual and physical aspects of natural turf. The artificial turf includes a resilient, slow recovery, foam layer that temporarily deforms proximate to where the club head contacts the artificial turf during a swing, thereby allowing an uninterrupted swing arc with a descending angle of attack and forming a virtual divot cavity that mimics physical aspects of a natural turf divot. Trans-chromic synthetic grass blades on the surface of the artificial turf exhibit a temporary color change caused by contact with the club head during a swing, thereby forming a virtual divot cavity that mimics visual aspects of a natural turf divot. The slow recovery foam and trans-chromic grass blades enable analysis of the golf swing based on the virtual divot. The artificial turf may be incorporated into a practice mat.

An indicator assembly for a golf club capable of checking a swing trajectory according to the present invention comprises an indicator which is attached to one side of the head of the golf club, has a sheet shape, has a plurality of marks spaced at intervals, and is made of a material that can be scratched by the blow of a golf ball. The indicator assembly for a golf club capable of checking a swing trajectory according to the present invention includes the marks on the indicator that can leave a scratch by colliding with the golf ball, thereby specifying the location of the scratch to determine the user's swing trajectory and the type of the formed pitch.

A contact location identification apparatus and method consists of a marking device with a first side and a second side. An attachment device is connected with the first side, where the attachment device removably attaches to an object. A marking receptor surface is provided on the second side, where the marking receptor surface holds a transferable marker substance.

A golf club head includes a top portion, a sole portion opposite the top portion, and a striking face configured to impact a golf ball. The striking face includes a face center and a variable thickness distribution such that the club head exhibits an Expected COR value of not less than 0.810, the Expected COR value being determined based on the following relationship $\mathrm{Expected}\mathrm{COR}=\underset{i=1}{\overset{n}{.Math.}}\underset{j=1}{\overset{m}{.Math.}}{p}_{\mathrm{ij}}*c_{\mathrm{ij}}$
The variable c.sub.ij corresponds to an average COR value associated with bin and the variable p.sub.ij corresponds to a bin-specific impact probability value. And the club head exhibits a characteristic time no greater than 257 microseconds.

The golf teaching set in the form of a subconscious habit based on established experience contains a special golf training club no. 0, a swing trainer for learning the position of the striking area at the moment of impact and training golf balls. Training golf club no. 0 has zero loft and the plane of the striking area is reflected in the club's grip. The swing trainer serves to develop the ability to perceive the position of the striking area at the moment of impact. It is used together with training club no. 0, where a pupil tries to achieve clean contact, i.e. under an angle of 0, between the striking area and the area of the flexible panel.
