Crack climbing is being sought out by more indoor climbers, however the issue that has arisen is that indoor features are fixed; cannot be removed or changed, thus climbing the feature indoors quickly loses its value as a method of getting stronger, or improving one's ability to adapt to outdoor environments. Currently if one wishes to practice or train for Crack climbing, they take to easy natural rock routes outdoors or build training boards out of wood to simulate common hand placements under the duress of a climb. Provided herein is an indoor-traditional crack climbing hold (I-TCCH) simulating a variety of Crack climbing situations and providing a “Settable” gym “Crack” to the simulated outdoor environment crack and the opportunity for climbers who wish to learn how to climb crack to have a safe way to learn about making correct hand placement, while conditioning themselves to natural rock surfaces.

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.

An exercise machine comprises an actuator, a motor coupled to the actuator, and a motor controller coupled to the motor. The motor controller is configured to receive an indication of a characteristic of a workout on the actuator, wherein the workout comprises a next exercise movement, determine a suggested weight for the next exercise movement, based at least in part on a physiological analysis of the workout characteristic, and control torque of the motor for the next exercise movement, based at least in part on the suggested weight.

In one example, a muscle exercise device includes a first arm and a second arm rotatably connected to the first arm, and the second arm and the first arm are configured to cooperatively define a recess having a shape that changes as one of the first arm and the second arm moves toward, or away from, the other of the first arm and the second arm. The muscle exercise device further includes a resistance element configured to reside in the recess and be compressed between the first arm and the second arm so as to assume a configuration similar to the shape of the recess. Finally, a wireless transmitter chip is disposed in either the first arm or the second arm, and the wireless transmitter chip is responsive to communications from an app residing on a user device.

Provided herein is a mechatronic simulator system that provides various types of unexpected perturbations to challenge the proactive and reactive balance control in subjects to thereby improve balance control of the subject. The system includes a motion capture unit and a processing unit capable of analyzing the subject’s response to the perturbations, provide real time feedback, adjust and/or determine training sessions.

A support part of a swimming start block. The front support part (18) is provided for a starting block (1) of a swimming race, which includes at least one base (9) to be fixed around a swimming pool, and a platform (5) which is mounted or fixed on the base (9). A foot of a swimmer as well as his hands are supported before the start of a race on the front support part. This front support part is arranged to be mounted interchangeably on a front portion of the platform (5) of the starting block (18) and can be an intelligent front support part with motion sensors and light source and race management electronics.

A starting block (1) including a supporting ledge device (10) for a start of a backstroke race. The supporting ledge device is at least partially integrated into the starting block. The supporting ledge device includes a support ledge (13) on which at least one foot of a swimmer can be supported before the start of a backstroke race. The support ledge is held from within a base (9) or a base plate of the starting block by fastening elements (11). Two flexible fastening elements in the form of straps are respectively connected to the two ends of the support ledge and to return means within the starting block at ends opposite the fixation to the support ledge.

The disclosure discloses a compensation method for output force of a strength-type intelligent fitness equipment, which relates to the field of intelligent fitness. The method comprises: obtaining the actual output force of the strength-type intelligent fitness equipment; obtaining the friction force of strength-type intelligent fitness equipment; compensating the output force of the strength-type intelligent fitness equipment based on the actual output force and the friction force.

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.
