A training apparatus includes an operating rod, a strength detector, a motion position detector, a boundary direction speed calculator, a motion position predicting unit, and a motion speed calculator. The operating rod moves a held limb. The strength detector outputs a strength component signal based on a magnitude of a strength component. The motion position detector detects a motion position of the operating rod. The boundary direction speed calculator calculates a boundary direction speed. The motion position predicting unit calculates a predicted motion position. The motion speed calculator calculates a speed including the boundary direction speed as the motion speed when the predicted motion position is predicted to be outside the operating rod mobile region.

A ball, and in particular a baseball or softball, including one or more sensors such as accelerometers and/or inertial measurement units, and systems and methods using the same to improve a pitcher's pitching performance are described herein. In some embodiments, the ball may include one or more inertial measurement units and/or accelerometers capable of monitoring motion of the ball while it is thrown. Once a ball is thrown, in response to the inertial measurement unit(s) and/or accelerometer(s), one or more indicators may be caused to perform an action. For example, one or more user interfaces may be used to display graphs for illustrating a trajectory of a ball after it has been thrown. Various statistics, such as velocity, a change in vertical displacement, a change in horizontal displacement, and a spin rate may also be indicated on the user interface.

An exercise assembly structured to perform different rowing routines characterized different rowing motions. A resistance device is movable within a chamber and is cooperatively structured therewith to resist such movement. A drive assembly includes two drive sections each independently connected in driving relation to said resistance device. A connector structure includes two connector members each attached to a handle and connected in driving relation to a different one of said drive sections. The handle is selectively movable through the plurality of different rowing motions, at least one of which results in the two drive sections concurrently driving the resistance member and being concurrently driven by the two connector members. At least one other rowing motion of the handle is defined by each drive section alternately driving the resistance member and being alternately driven by interconnected ones of said connector members.

A system to optimize diaphragmatic breathing is disclosed. The system has a first sensor to measure breathing movement of a user's abdomen and output a signal related to the movement of the user's abdomen, a second sensor to measure breathing movement of the user's chest and output a signal related to the movement of the user's chest; and a control device communicatively coupled with the first sensor and the second sensor. The control device has one or more processors, a memory comprising set of program modules executable by one or more processors. an assessment module for receiving the signal from the first sensor and second sensor and converting the signals to a data input, and for comparing the data input to a predetermined data range representative of proper diaphragmatic breathing for the user and a communication interface for providing feedback based on the assessment modules comparison of the data input and the predetermined range so as to optimize the user's diaphragmatic breathing. A method for optimizing diaphragmatic breathing is also disclosed.

A putting stroke sensor is attachable to a putter head for measuring characteristics of a putting stroke. A motion sensor integrated circuit is configured to measure acceleration of the putter head along several axes and rotation of the putter head around the several axes during a putting stroke. A processor is programmed to determine a speed, a position and an orientation of the putter head at selective intervals during the putting stroke.

The present invention discloses a multifunctional abdominal exercise wheel, comprising a main body, support members, a central pipe fitting, and a spring barrel. Two ends of the central pipe fitting are each provided with a support rotating member. The support rotating member is pivoted to a support member. The central pipe fitting is inserted into the spring barrel and fixed. The spring barrel is provided with a power spring. The main body is fixedly provided with a single-chip microcomputer, and a display apparatus, a sensor, and a button separately electrically connected to the single-chip microcomputer. Therefore, motion data can be displayed, the stroke and resistance of the abdominal exercise wheel can be adjusted, torsion outputs are stable, and springback noise is small.

Systems and methods for motion capture and analysis are described. The system may include a motion sensor unit configured to capture data associated with movement of an object. The motion sensor unit is configured to be directly or indirectly coupled to the movement object at a first location. The system also includes a processor to process the captured data to determine one or more values and to translate the data and/or values to correspond to a second location on the movement object located away from the first location. The data and/or values, including translated data and/or values, may be transmitted by wireless transmitter and displayed by a display unit.

A device is provided. The device includes one or more of a plurality of sensor/light source groups, each including a sensor, a first light source of a first color, and a second light source of a second color, arranged in sequence along an expected direction of travel of an object.
