A golf swing training tool including an arm band (which connects the elbows) and the club shaft are connected by a cord maintain a prescribed grip angle. The arm band is configured to adjust a distance between the elbows. An elastic clip locks onto the club shaft and is configured to encircle the club shaft, and enables easy changing of the grip angle by using an opening lever to change the locking point with a single touch. As a result, frequent changes in grip angle can be made much more easily. Three types of cords are employed, a low-elasticity cord, a high-elasticity cord, and a cord combining both are used to achieve twelve different types of training methods.

Devices, systems, and methods for training baseball and softball batters, to identify types of pitched balls (fast ball, curve ball, slider and changeup) and locations (strike or non-strike zone) of pitched balls in order to increase hitting accuracy A motion sensor can be triggered by the leading foot of a pitcher. The motion sensor can use cone or fan shaped sensor to detect the passage of a pitched ball from the pitcher. When the motion sensor is triggered, a signal can be sent to a black out lens that blocks the vision of a hitter being trained to identify the types and locations of the pitched balls. The training includes changing the lens from transparent to opaque at selected distances between the hitter and the pitcher. Batters can be trained to keep their eyes on the pitched balls until the ball reaches the batter. Golfers can be trained to not have to look up when their club hits the ball, where the black out lens are go opaque when the golf swing passes into the motion sensor.

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 system and method for analyzing and improving the performance of a body motion of an animal or human subject requires instrumenting a subject with inertial sensors, monitoring a body motion of interest, converting sensor data into motion data and animation, comparing the motion data with existing data for motion related performance parameters, providing a real-time, information rich, animation and data display of the results in color coded displays; and based on the results prescribing a training regime with exercises selected from a library of standardized exercises using standardized tools and training aids.

A golf training aid comprises a bottom piece with a slot. A vertical member attaches from the bottom piece to an upper member. A mechanism has sliders configured to slide up and down the mechanism, wherein the mechanism is attached to the upper member. An arm cuff is attached to each slider, configured to receive human arms. The upper member has a connector that attaches to a top end of a golf club and the golf club slides into the slot of the bottom piece.

A golf training device for use in a glove or under the ball of the foot or under the heel, which includes pressure sensors, a visual display which is flexibly connected to the sensors for adjusting the position to suit the wearer, and a controller programmed to provide visual feedback to indicate if the pressure is appropriate or not. For a glove the sensors are located on the palm at the junction with the first three fmgers. There are two or more sensors and for each sensor the controller can display by an appropriately coloured LED that the pressure detected by the sensor is too light, appropriate or too tight. For a shoe the sensors are located under the ball of the foot or the heel and the LEDs indicate whether the weight is appropriately on the ball of the foot or on the heel.

According to one aspect of the present invention, a method of improving a participant's ability to move an object toward a desired target through athletic movement is provided. The method comprises establishing a point of focus that is positioned outward from a participant's body. The method further comprises instructing the participant to continuously move the point of focus through one or more series of bodily movements within the field of vision of the participant. By shifting his or her emphasis on continuously moving the point of focus, the participant is able to improve focus and concentration, and eliminate the stress and anxiety associated with executing an athletic movement. The method also naturally triggers correct body mechanics, including the proper sequential release of the participant's joints.

An apparatus for golf training includes a wrist strap and a ring which are shaped and sized to be worn by a user. A cable extends between the wrist strap and the ring, and certain movements thereof are configured to provide an indication of improper swing form using an audible stimulus

A golf hip-turn training device according to the present disclosure includes: an anchor section including a body having a band shape, a first ring coupled at a second side of the body, and a fixer that is formed at a first side of the body and configured to be coupled to a fixed object; a resistance load section including an elastic member that has a rope shape, and one or more second rings that are coupled to ends of the elastic member and fastened to the first ring; and a strap section having a loop band shape and including a third ring coupled at a first side of the strap section to hold the elastic member and to enable the elastic member to pivot around the third ring, wherein a second side is formed to wrap around a hip and a portion of a femoral region of a user.

A wrist worn muscle movement monitoring device includes a wrist strap; a sensor that responds to muscle movement at a wrist wearing the wrist strap; and monitoring circuitry connected to the sensor.
