The present invention concerns a gymnastic accessory including a twisting ring with an external ring and an internal ring, wherein the two rings are concentrically connected and rotatable in relation to each other about a common axis, wherein the external ring typically includes two connecting devices that are arranged symmetrically at the outer periphery and adapted for joining with an unyielding or elastic rope. The second ring include connecting means at the periphery, the connecting means adapted for mounting of connecting elements for a twisting belt. The invention further concerns a method for reconfiguring such a gymnastic accessory. The new feature of the gymnastic accessory according to the invention is that the twisting ring further include a number of the connecting elements in the form of straps, wherein one or more and preferably all the straps are arranged with joining means for joining with complementary joining means either on the strap itself, on the second ring or on a twisting belt, wherein the straps and/or the joining means further include adjusting means for adjusting the length of the straps and thereby of the spacing between the twisting belt and the second ring of the twisting ring.

The present disclosure provides a jump detection system for inertial measurement unit (IMU) integrated with a barometric altimeter in the same device (IMU-baro). The processor is configured to record time-series data of both a vertical component of the measured IMU-baro acceleration and the estimated vertical velocity of the IMU-baro, detect a potential jump by comparing the vertical component of the measured IMU-baro acceleration to one or more acceleration thresholds, and, validate the potential jump by comparing a difference between a maximum velocity and a minimum velocity within a vicinity of the potential jump in the time-series data of the estimated vertical velocity of the IMU-baro to a velocity threshold.

An air step board for health is disclosed. The step board has an upper plate on the upper surface of a board frame, and a shock absorbing leg on a corner of an underside of the board frame. The board frame is formed using a synthetic resin material through injection molding such that a seating part is provided on the upper surface of the board frame, and a reinforcing rib is provided in the seating part to reduce a weight of the board frame and impart sufficient strength. A handle is provided on at least one side of the board frame. In this invention, the board frame having the reinforcing rib is manufactured through injection molding, thus enhancing the durability of the board frame, permitting mass production, and ensuring easy workability, and a reinforcing plate is provided between the reinforcing ribs and the upper plate, thus reliably withstanding shocks.
