The invention relates to a white-water river, comprising a river bed capable of guiding a current of water between an upper inlet of the bed and a lower outlet of the bed, and including water-feeding means for injecting a stream of water at the upper inlet of the bed. The river bed is made up of a series of individual bed modules, adjacent to one another, and assembled via respective transverse contact surfaces. The individual bed modules are supported via a lower surface by a modular lattice bearing structure.

A combination paddle and fishing rod device is disclosed. The device may incorporate a single ended paddle or double ended paddle. In any embodiment, the device allows a fishing reel to be mounted to the shaft of the paddle. The shaft forms a portion of the fishing rod supporting one or more eyelets for guiding fishing line from a fishing reel mounted to the shaft. In one embodiment, the eyelets are connected to the shaft and or an oar blade. In another embodiment, a short fishing rod section having one or more eyelets is connected to the shaft. The device is configured to permit fishing while a user propels a watercraft.

A system and method for measuring and normalizing physical resistance for athletic activities and fitness equipment are disclosed. A particular embodiment includes: measuring a level of physical resistance in an athletic activity; generating sensor data indicative of the measured level of physical resistance; using the sensor data to determine if the measured level of physical resistance will achieve a desired performance level in the athletic activity; and automatically generating control signals to adjust the level of physical resistance if the measured level of physical resistance is unlikely to achieve the desired performance level in the athletic activity.

Apparatus and associated methods relate to a balance exercise training equipment having a planar platform with a ballast assembly that lowers its center of mass below a ball-and-socket joint. In an illustrative example, the planar platform may couple to a support assembly through the ball and socket joint to pivot and rotate relative to the support assembly. The ballast assembly may include laterally extending members to releasably receive and retain ballast plates. In response to the laterally extending members receiving and retaining ballast plates, the center of mass may descend below a pivot point of the ball-and-socket joint. In a mount or dismount mode, a locking mechanism may lock the planar platform in a predetermined position to facilitate mounting and dismounting onto the planar platform. Advantageously, a user may adjust the center of mass in accordance with a user's skill level or exercise preference.

An exercise machine includes a cyclical actuator and a mechanical energy storage device. Connective structure operatively connects the cyclical actuator to the mechanical energy storage device. Motion of the cyclical actuator urges physical motion of and energy storage in the mechanical energy storage device. The exercise machine further includes an electric machine. A communication pathway enables exchange of data between multiple associated exercise machines such that multiple associated operators on multiple associated exercise machines have a common experience.

A device for performing sports exercises includes a pivoting boom which has a hollow profile shape, of which at least two opposing surfaces together form a linear guide path. The boom has means for attaching a first range of removable accessories, and includes: a mobile carriage for the means for attaching a second range of removable accessories; a means of generating resisting torque; first and second means for transmitting the resisting torque; the means of generating resisting torque is connected to the means for transmitting by virtue of a belt or a chain; a folding or removable arm; a base which includes means for positioning and maintaining the boom in vertical and horizontal positions; a pivot connection arranged between the base and the boom, to move the latter from a horizontal position to a vertical position and vice versa.

A paddling action simulating exerciser in the form of a kayaking trainer that includes pole, a cord that extends along the pole and linearly displaceably passes therethrough, a hollow spacer that extends between a seating facility and an anchoring layout including a cord guiding layout via which the free ends of the cord are secured to a spring. A multi-directionally adjustable footplate facility that includes an upright foot abutment plate fitted with a heel rest and a toe strap is fitted along the spacer. The spacer, seating facility, leg, footplate facility and guiding layout in constituting a trainer core assembly are laterally rockable by way of rocking formations fitting along slots.

A portable paddleboard exercise apparatus having a balance platform, an elongated member, a paddle handle, and a number of resistance bands. The apparatus may further include a frame with one or more support members configured to support the balance platform. The balance platform includes an upper surface for a user to balance thereon. The elongated member extends from the balance platform. The resistance bands extend from a distal end of the elongated member to the paddle handle. A user may balance on the balance platform in one of a number of positions while pulling the paddle handle against a resistive force generated by the resistance bands.

A paddling action simulating exerciser in the form of a kayaking trainer 10 comprises a paddle action simulating formation. In the form of a paddle simulating pole 12, a cord 14 that extends along the pole 12 in linearly displaceably passing therethrough, a hollow spacer 18 extending between a seating facility 20 and an anchoring layout including a cord guiding layout 22 via which the free ends 14.3, 14.4 of the cord 14 are secured to a spring 24. A multi-directionally adjustable footplate facility 40 including an upright foot abutment plate 42 fitted with a heel rest 44 and a toe strap 46 is fitted along the spacer 18. The spacer 18, seating facility 20, leg 30, footplate facility 40 and guiding layout 22 in constituting a trainer core assembly 28 is laterally rockable by way of rocking formations 78 fitting along slots 80.

A dual-mode exercise apparatus may include an articulating arm assembly coupled through a joint to a support assembly. In an illustrative embodiment, the arm assembly may include a seat centrally mounted above a ball-and-socket joint and a stabilizer member for the hands and/or feet of the user. In a first mode of operation a user sits on the seat and uses his or her core muscles to articulate the seat on the ball-and-socket joint against the resistance provided by, for instance, weights mounted on distal portions of the arm assembly. In certain embodiments the apparatus may further provide a second mode of operation which simulates rowing a kayak. In a corresponding illustrative embodiment a user sits in a second seat positioned rearward of the arm assembly and the arm assembly includes handle members. In operation the user articulates the handles in a manner akin to rowing a kayak.
