A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed.

An exercise recommendation system determines a current capability of a user. The exercise recommendation system accesses an exercise history for a user. The exercise history comprises an exercise performed by the user and a capability of the user each time the user performed the exercise. The exercise recommendation system partitions the exercise history into a plurality of time periods, and, for each time period, computes an aggregate capability of the user for the exercise during the time period. The exercise recommendation system calculates a moving average capability of the user for the exercise based on the aggregate capabilities and determines a current capability of the user for the exercise based on the moving average capability. The current capability of the user may be discounted at least in part based on how recently the user performed the exercise.

Methods and systems are provided for measuring anatomical dimensions from a single two-dimensional (2D) digital image. The digital image is taken from the front/anterior view using a mobile, handheld communication device. The linear measurements are used to estimate the body volume of the individual. Total body density is calculated from estimated body volume and body weight. Body composition (fat mass and fat-free mass) of the individual is derived from density using known mathematical conversion formulas. A method for estimating body composition analysis is provided. Systems and methods are provided that determine an individual's fitness by determining body composition of the individual using a picture of the individual, determining the individual's VO.sub.2 max based on the individual's movement (e.g., walking and/or running a measured distance over a measured amount of time), and determining the individual's fitness based on the body composition and the determined VO.sub.2 max.

The present invention relates to a novel fitness weight device designed to allow users to customize dumbbell weights by filling the air chambers with air. The device comprises a dumbbell-styled weight with an inflatable air chamber. The devices can be inflated via a push button. Users can inflate the dumbbell devices to a desired weight for customized workouts. Once finished, the user can activate the air release valve to compact or retract the dumbbell for storage.

The present disclosure relates to a stationary exercise apparatus for indoor cycle training (1), i.e. a stationary exercise bicycle, preferably provided with a magnetic resistance unit (15). One embodiment relates to a stationary exercise bike comprising a flywheel (10) defining a radial gap (25) in the periphery wherein at least the periphery of the flywheel (10) has ferromagnetic properties, and wherein a magnetic resistance unit (15) is configured to controllably insert one, two or more magnets into said radial gap.

An elliptical exercise machine may include a base, one or more upright stanchions coupled to the base and extending upward from the base and supporting first and second cranks. The first crank may support a first crank arm. The first crank arm may support a first pedal leg hanging downward from the first crank arm. The first pedal leg may support a right pedal. The right pedal may be configured to swing forward and rearward and to raise upward and lower downward. The second crank may support a second crank arm. The second crank arm may support a second pedal leg hanging downward from the second crank arm. The second pedal leg may support a left pedal. The left pedal may be configured to swing forward and rearward and to raise upward and lower downward.

An electromechanical device for rehabilitation includes pedals coupled to radially-adjustable couplings, an electric motor coupled to the pedals via the radially-adjustable couplings, and a control system including a processing device operatively coupled to the electric motor. The processing device configured to, responsive to a first trigger condition occurring, control the electric motor to operate in a passive mode by independently driving the radially-adjustable couplings rotationally coupled to the pedals. The processing device also configured to, responsive to a second trigger condition occurring, control the electric motor to operate in an active-assisted mode by measuring revolutions per minute of the radially-adjustable couplings, and cause the electric motor to drive the radially-adjustable couplings when the measured revolutions per minute satisfy a threshold condition, and responsive to a third trigger condition occurring, control the electric motor to operate in a resistive mode by providing resistance to rotation of the radially-adjustable couplings.

An apparatus, method, and a non-transitory programmed medium provide a structure to move a heavy bag to simulate sparring along with a method and programmed media to provide selective training experiences. Drive motors in a Cartesian gantry provide multi-axis lateral motion in a horizontal plane. The heavy bag is instrumented to generate information indicative of performance of the user. Also, the heavy bag receives information to prompt a user with indicators such as LEDs. A moving target simulates a boxing match. A user responds to motions of a heavy bag in an X-Y plane whether toward or away from the user. It may be used as a sparring partner. Electronic controls provide a pre-selected pattern of movement. Training programs include sequences designed by professional boxers and trainers. Controls may be adaptive to vary responses of the apparatus in response to user performance.

An exerciser includes: sensor installation units provided to be spaced apart from and face each other in a direction parallel; a radiation unit for radiating light, in a first sensor installation unit; a light receiving unit for receiving the light radiated from the radiation unit, in a second sensor installation unit; a speed detection unit for detecting a speed of the golf ball by checking a moment the golf ball passes; a position measurement unit for measuring a position of the golf ball; an operation control unit for performing calculation to detect an initial position value of the golf ball and a moving speed Vb and a moving distance Hb of the golf ball; and a storage unit for storing the measured speed Vb and distance Hb of the golf ball.

An isometric exercise system comprised of a network-enabled isometric exercise apparatus, force correction equations, and an isometric exercise companion software application. The isometric exercise apparatus can include force-receiving components, a measurement component, a pivot assembly, and a structural assembly. The measurement component can measure the amount of applied force. The pivot assembly can rotationally transfer the applied force to the measurement component. Force analysis of exercises can indicate that only a tangential component of the applied force is mechanically transferred to the measurement component via the pivot assembly. The force correction equations can translate the measured force into the tangential force transferred by the pivot assembly. The isometric exercise companion software application can present the amount of weight manipulated by the user to perform the exercise calculated using the force correction equation and the measured force. This calculation can have greater accuracy and consistency than utilizing the measured force.
