Described herein are methods for determining a target musculoskeletal activity cycle (MSKC) to cardiac cycle (CC) timing relationship. The method may include detecting a signal responsive to a cyclically-varying arterial blood flow at a location on a head of a user; providing a recurrent prompt at a frequency of the heart pump cycle using the signal, such that the signal correlates with a magnitude of blood flow adjacent to the location, and the recurrent prompt is provided to guide the user to time performance of a component of a rhythmic musculoskeletal activity with the recurrent prompt; and guiding the user to adjust a timing of the component of the rhythmic musculoskeletal activity to substantially maximize a magnitude of the signal. In some embodiments, the method further includes generating the recurrent prompt by amplifying the sound generated by the blood flow in or in proximity to an ear of the user.

A system for providing player training including a grid of individually powered, processor controlled and communicable lighting elements and sensors which are embedded within a playing surface associated with the event, the lighting elements interfacing with at least one of a player worn sensor and/or a remote processor device for providing a visual illustration of any number of parameters associated with an actual player performance, including real time motion progressions of the player which are represented on the field surface and/or recreated on a processor driven screen which films or otherwise tracks the event. The simulated progressions can further replicate the desired motions of the positional player's intended motions or those of an opposing positional player and in lieu of the actual player being on the playing surface.

It is disclosed an apparatus for restoring voluntary control of locomotion in a subject suffering from a neuromotor impairment comprising a multidirectional trunk support system and a device for epidural electrical stimulation. The robotic interface is capable of evaluating, enabling and training motor pattern generation and balance across a variety of natural walking behaviors in subjects with neuromotor impairments. Optionally, pharmacological cocktails can be administered to enhance rehabilitation results. It is also disclosed a method for the evaluation, enablement and training of a subject suffering from neuromotor impairments by combining robotically assisted evaluation tools with sophisticated neurobiomechanical and statistical analyses. A method for the rehabilitation (by this term also comprising restoring voluntary control of locomotion) of a subject suffering from a neuromotor impairment in particular partial or total paralysis of limbs, is also disclosed.

A device is used for carrying out movements by shifting the center of gravity and/or actuating muscles of a human body. A user lies on the device and shifts the center of gravity by moving his or her hip region in order to incline a movable part of the device including the user's own body in different directions. Furthermore, the user wears video goggles or the like during the process and can move in a virtual environment using the overall system, which includes the video goggles and the movement device and can interact with these. The movements caused by the user can be generated solely using gravity by shifting the center of gravity. Additionally, the movements of the device are influenced by motors or dampers arranged in or on the device.

Virtual golf system for playing golf, comprising a plurality of trackable golf balls, wherein each golf ball comprises transmitting means for broadcasting electromagnetic beacon signals for detecting a position of the golf ball, a position determination unit comprising three receiving antenna's arranged for receiving beacon signals broadcasted by any of said plurality of trackable golf balls, and wherein said position determination unit is arranged to determine a position of said golf ball on a driving range based on time differences of a broadcasted beacon signal received by said receiving antenna's. A plurality of trackable golf balls and a plurality of players may be active at the same time. Trackable golf balls may be paired with specific players. A game controller advances a virtual game of golf each time a trackable golf ball is stroked by a player.

A fitness structure includes a bar having a first end portion and a second end portion, a pair of bar support portions provided at each side of the bar and having a plurality of bar support members to place the bar at a plurality of heights, a first load portion and a second load portion spaced apart from the bar to a certain degree and facing each other, a first cable coupled between the first end portion of the bar and the first load portion, a second cable coupled between the second end portion of the bar and the second load portion. Heights of the first load portion and the second load portion vary depending on a height of one of the plurality of bar support members at which the bar is detachably placed.

An interactive exercise system with apparatus and methods to optimize muscle strength for rehabilitation, to improve or maintain fitness, and to enhance the performance of athletes. The system uses an electronically controlled linear actuator to generate resistance against the muscular force exerted by the user. The system includes sensors configured to detect acceleration, speed, velocity, position, direction of movement, duration, and the force applied by the user. A control system preferably continuously monitors the sensors, and instantaneously adjusts the adaptive actuator. This provides a proportional counterforce to the user force throughout the entire range-of-motion. A display panel allows the user to interact with the system in real-time. The objective of the user is to synchronize the exercise performance with a selected target goal, by correlating the user's movement relative to a position on a display panel.

Methods for determining performance information for an object located within an area include obtaining magnetic field information for the area, measuring first magnetic field data when the object is located at a first position within the area, and determining performance information for the object within the area based on the magnetic field information for the area and the first magnetic field data.

An electronics module in a gaming device includes an inertial measurement unit (“IMU”) for detecting acceleration motion, angular movements, and an optics assembly to optimally calculate a moment of impact and to predict a virtual trajectory of a virtual golf ball or other hypothetical object. The virtual trajectory of the target object may be displayed on a display screen either on the gaming device itself, on a computer, or on a television display. A haptics member, such as a vibration or sound element is positioned in the shaft housing and actuated to simulate a ball impact when the shaft housing is indicative of a swing.

A method for identifying and correcting muscular and skeletal disbalances through exercise includes recording, by a processor, using at least one sensor coupled to the processor, an exercise motion performed by a user, identifying, by the processor, a motion deficiency of the user based on the detected exercise motion, formulating, by the processor, a corrective motion based on the detected motion deficiency, and providing, by the processor, the corrective motion to the user, which also includes identifying motion deficiencies as far as range of motion, balance, symmetry, smoothness, strength, stamina and other motion characteristics, formulating corrective exercise program that involves multiple training machines, formulating exercises in terms of number of repetitions, cadence (frequency) or motion, range of motion, added resistance levels, communicating the corrective exercise program via the screen embedded on each machine, and guiding the user through each exercise, directing user to change exercise machines.
