A golf alignment training tool for indicating a target line. The golf alignment training tool is positional on and securable to the ground to indicate a proper golf stance alignment and a proper target line for hitting a golf ball. At least one retractable cord is attached to a recoil assembly encapsulated within a housing that is securable to the ground with a golf tee. The retractable cord extends out of the housing and a distal end of the cord is attached to a ring that is similarly securable to the ground with a golf tee to create a target line. When no longer needed, the cord is retracted back into the housing with the housing and ring abutting for compact storage.

A golf training aid is disclosed for use with alignment sticks. The golf training aid includes an elongate member with a longitudinal axis and a first and second set of holes. The first set of holes is space apart farther than the second set. The elongate ember also has a target alignment hole positioned in between the first and second set of holes. All the holes are constructed to receive and hold an alignment stick. The golf training aid has least two configurations: a wide hitting box configuration and a narrow box configuration.

A swing aid is provided, comprising: a support member, having an elongated shape with a first end and a second end; a first assembly, comprising a first shell and a second shell, the first shell and the second shell being pivotally connected to the first end, the first shell and the second shell being rotatable around the first end to adjust included angles with respect to the support member, respectively; a second assembly, comprising a first indicator and a second indicator, and the first indicator and the second indicator being pivotally connected to the second end, the first indicator and the second indicator being rotatable around the second end to adjust the included angles with respect to the support member, respectively.

This document relates to a multi-function golf training aid for square alignment. An apparatus for golf comprising: a base with a lower surface and an upper surface, the lower surface is substantially planar and having a length and a width, the lower surface includes a groove, in a tunnel shape, across the width to allow a golf alignment stick to fit within the groove while remaining part of the lower surface is resting on a golfing surface; an adjustable vertical member with a near end and a distal end, the near end is affixed to the upper surface of the base and the adjustable vertical member rises in an upward direction away from the lower surface of the base, and a holder affixed to the adjustable vertical member at a lower surface of the holder, wherein an upper surface of the holder is configured to hold a line laser.

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.

A golf practice tool is provided having a columnar box, wherein the columnar box is provided with a shoulder belt and the columnar box is carried on the back of the golf player. The columnar box has a substantially flat upper surface. A plurality of striped line patterns or striped patterns substantially parallel to a side surface, which touches a back of a person and is called a back touch side surface, of the columnar box are drawn on the upper surface. The degree of inclination of the upper body of the golf player when playing golf can be adjusted by using the striped line patterns or the striped patterns. On side surfaces other than the back touch side surface of the columnar box, a plurality of vertical striped line patterns or vertical striped patterns are drawn substantially at right angles to the bottom surface of the columnar box. The degree of rotation of the upper body at a golf swing can be adjusted by using the vertical striped line patterns or the vertical striped patterns.

A golf hip-turn timing practice device according to the present disclosure includes: a fastening belt; a first retainer; a plurality of second retainers; and a hip-turn link stick that is fitted in the first retainer and the second retainers in the longitudinal direction of the fastening belt to be fixed at the position and is longer than the width of shoulders. The golf hip-turn timing practice device provides an advantage in that the golf hip-turn timing practice device enables correct swing timing practice by timing a hip-turn, which is a movement of a lower body, with the movements of the arms and hands of the upper body in golf swing. Further, the golf hip-turn timing practice device provides immediate feedback when the timing is wrong, is easily worn on the waist, and corrects a wrong swing by accurately showing the plane by hip-turn.

Disclosed is a mat, method, and program for measuring a golf posture that are capable of measuring a golf club swing speed. The golf posture measuring mat capable includes a sensor unit sensing a pressure corresponding to a golf posture of a user and a trajectory of a head of a golf club, a control unit analyzing the golf posture of the user and a swing speed of the golf club based on a sensed signal of the sensor unit, a display unit displaying analysis data analyzed by the control unit, and a storage unit storing the analysis data and reference data. A plurality of sensors in the sensor unit are arranged one-dimensionally or two-dimensionally on a mat plate. Each of the plurality of sensors includes a single sensor including one among a capacitive pressure sensor, a resistive pressure sensor, and a hybrid pressure sensor, or includes a composite sensor including two or more among the capacitive pressure sensor, the resistive pressure sensor, and the hybrid pressure sensor.

A portable putting mat with knobs on the sides to adjust particular sections of the surface. By varying the amount of slope between where the ball is hit and the hole, golfers will be able to practice on a more realistic surface.

Described herein are devices and systems relating to sports training equipment, for example, for baseball. These devices and systems can comprise a mat with markers identifying a plurality of positions on the mat. In some embodiments, the system can comprise removably attachable footpads to identify ideal foot positions for an athletic performance. In some embodiments, the footpads comprise one or more pressure sensors. The system can comprise one or more position sensors on a ball, and one or more position sensors removably attachable to a hand-held sports instrument. In some embodiments, the system can comprise a memory, communicatively coupled to a processor and a camera, with executable instructions to implement a set-up component, a user recognition component, a practice component, and instructional component, and a play component.
