A snowboard support apparatus, attached to the snowboard in such a way that it extends from the board and provides a physical support for the rider to lean against in order to aid in the process of learning to snowboard. The support apparatus provides support to the rider to allow them to develop skills in being able to ride a snowboard in an incremental and natural manner without constraining the riding experience.

A system for monitoring performance of a user includes at least one processor, and at least one memory including a computer program code. The at least one memory and the computer program code are configured, with the at least one processor, to cause the system to perform operations including obtaining force data measured by at least one force sensor coupled with one or more poles and velocity data measured by at least one sensor for measuring velocity of the user, determining poling power based on the force data and the velocity data, and outputting a poling power indicator based on the determined poling power.

A pivotable coupling assembly having lateral flexure and apparatuses utilizing the pivotable coupling assembly. The pivotable coupling assembly includes a link that is adjustably connected to a first member, such as a board, and a yoke that is connected to a second member, such as a base. The yoke is configured to pivotably receive the link, allowing the first member to pivot longitudinally relative to the second member. The link is fabricated from a material having sufficient stiffness to support the weight of a board and a rider, while also having sufficient flexure to allow the link to bend laterally when stressed. The pivotable coupling assembly thereby allows the first member to rotate or bend laterally, while still permitting longitudinal movement thereof. The bidirectional movement provided by the coupling assembly mimics the movement or control of a board, such as a snowboard, under normal conditions when snowboarding.

A device for training purposes or recreational activities using structures having a range of properties. The training device may include a board made of wood (or other material such as metal, rubber, plastic, or a combination thereof) and one or more suspension assemblies coupled to the bottom surface of the board. The assembly is adapted to be coupled to a longitudinal or a lateral slot on the board. The slots allow a user to longitudinally and laterally move the assembly without uncoupling it from the board, thereby allowing the user to easily position and re-position the assembly on the board to change the performance of the training device. Each of the assemblies may include an inflatable base having a polygon or circular shape. The base is for providing a cushioning effect when the board impacts the ground after a user performs an aerial maneuver.

The invention relates to a method for detecting and calculating the duration of a jump effected by an individual, comprising the following steps: Detection of a moment associated with a landing following the jump, this step comprising a sub-step of detecting an acceleration peak of an amplitude greater than a first threshold amplitude, within the acceleration measurements provided by a three-axis accelerometer, on board a watch worn on the wrist of the individual. Detection of a jump phase, by detection, in a temporal window finishing at the moment of landing, of a succession of acceleration measurements between 0 g and 0.5 g during a duration greater than a first threshold duration.

A user customized training system according to the present invention includes a sensor module configured to sense a user's motion; a memory in which a program for training is stored; and a processor configured to execute the program stored in the memory, wherein, when the program is executed, the processor acquires coordinates that correspond to the sensed motion, compares the user's motion with pre-stored erroneous motions on the basis of body information generated on the basis of the coordinates, provides a pre-stored set of motion data when a result of the comparison indicates that the user's motion corresponds to an erroneous motion, and, when the sensor module senses a motion of the user corresponding to the set of motion data, provides a training set corresponding to a result of analyzing the sensed motion.

A body weight support (BWS) system is disclosed. The BWS system includes a harness coupled to a plurality of cables, wherein the harness is worn by a subject, an actuator for each of the plurality of cables, each actuator configured to place a tension on a corresponding cable in response to an electrical signal, at least one force sensor configured to provide an electrical signal corresponding to forces applied to the harness, at least one motion sensor configured to provide an electrical signal corresponding to changes in acceleration of the subject, and a controller configured to control the plurality of actuators.
