There is provided a health promotion system using a wireless and ropeless jump rope. When a plurality of users use a plurality of wireless and ropeless jump rope apparatuses, each wireless and ropeless jump rope apparatus transmits each user's weight, the number of jumps made by the user and the time of using the wireless and ropeless jump rope to an external health promotion server. The health promotion server analyzes the user's weight, the number of jumps made by the user and the time of using the wireless and ropeless jump rope as transmitted and provides an instructor with the information of the number of jumps made by the user and the analyzed health-relevant data. The instructor who receives the information of the number of jumps made by the user and the analyzed health-relevant data is able to improve the health of the user.

A golf ball with embedded electronics to allow proximity to be tracked and to monitor golfer performance is disclosed. The golf ball comprises a processor connected to an accelerometer, communications circuitry, a spin detector, and memory, wherein the processor stores accelerometer data from the accelerometer and rotation data regarding rotation of the spin detector in the memory. The processor converts the data regarding the rotation of the spin detector into a rotation speed and a rotation direction, said rotation speed determined by a frequency of the data, and said rotation direction determined by a magnitude of the data. The communications circuitry is configured to communicate the accelerometer data, the rotation direction, and the rotation speed to a central interrogator for analysis of a golfer's performance.

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.

Disclosed is a muscle specific exercise device. The device may provide passive or active resistance training throughout an angular range of motion. The device may be low profile, and worn by a wearer, such as beneath conventional clothing. Exercise of selective joints or motion of the body may thereby be accomplished throughout the wearer's normal daily activities, without the need for access to conventional exercise equipment. Alternatively, the device may be worn as a supplemental training tool during conventional training techniques.

This disclosure relates to systems, media, and methods for quantifying and monitoring exercise parameters and/or motion parameters, including performing data acquisition, analysis, and providing scientifically valid, clinically relevant, and/or actionable diagnostic feedback. Disclosed embodiments may receive real-time sensor data from a motion sensor or sensors mounted on a user and/or equipment while a user performs a test motion. Disclosed embodiments may also calculate a test motion profile based on the real-time sensor data, the test motion profile describing a multi-dimensional representation of the test motion performed by the user or computed motion profiles. Disclosed embodiments may include comparing the test motion profile to a template motion profile to determine a deviation amount for the test motion profile indicating how the test motion deviated from the template motion profile. Still further embodiments may correlate test motion profiles over time with health indicators.

A walking training apparatus includes: a treadmill; a walking assistance apparatus configured to be mounted on a leg part of a user and assist the user's walking; a first pulling means for pulling at least one of the walking assistance apparatus and the leg part of the user upward and frontward; a second pulling means for pulling at least one of the walking assistance apparatus and the leg part of the user upward and rearward; and control means for controlling, while the treadmill is not being operated, pulling forces of the first pulling means and the second pulling means in such a way that the direction of a resultant pulling force, which is a resultant force of the pulling force of the first pulling means and the pulling force of the second pulling means, is changed rearward compared to a case in which the treadmill is being operated.

A training or exercise apparatus may have a base and an adjacent movable armature or frame that carries a riding member, or shuttle, or carrier. The carrier has an engagement interface with an element of sporting or exercise equipment. The sporting or exercise equipment is engaged by the user, typically by being grasped. The apparatus defines a physical or virtual schedule describing an arc for a swing in the particular activity. The apparatus may include a manual or electronic means of imposing resistance to the motion. This resistance may be adjustable, and may be programmable as a function of one or both of position and speed. The apparatus may include an array of sensors such as may be used to determine the pre-existing stroke, and such as may be monitored during training to assess progress. The apparatus may be operated passively, or it may be operated interactively in a manner in which real-time feedback causes the apparatus to adjust resistance to the motion.

Ball with line (20) for training purposes where the line (20) is rotatably attached to the ball in a special suspension, the suspension of the line being arranged in a particular cavity (14) arranged in a confined space between the ball's airtight bladder (13) and its outer layer (12). The cavity (14) typically has circular cross section and may include a centre member (21) to which the line is attached and an annular element (24) surrounding this, optionally comprising a battery for providing power to a sensor and optionally to a communication device.

A weight training apparatus includes a telescoping pivot arm comprised of a concentric arrangement of an outer tube and an inner tube and configured to pivot about an axis and receive a weight at a predetermined position. The weight training apparatus further includes an actuator attached to the telescoping pivot arm and configured to cause relative motion between the inner tube and the outer tube to change a length between the predetermined position and the axis. The weight training apparatus further includes a sensor configured to output a signal indicative of an angular position of the telescoping pivot arm about the axis and a controller programmed to operate the actuator to cause the length to change based on the signal to achieve a target resistance profile.

Provided is a joint movement aid, which has a simple structure and is lightweight and which a user can easily put on and take off, and which has a novel structure capable of safely supporting a walking without impeding a user's autonomous fall-preventing movement even in a case of a disturbance such as external force on the user in a transverse direction. The walking movement aid includes a right and left pair of assisting units provided with drive sources, which exert a pulling force on flexible auxiliary force transmission parts, and a control member for controlling the respective drive sources of the assisting units corresponding to changes in a joint angle with user's hip joints.
