The present invention is a tethered resistance swim training apparatus with a pulley that includes an electronic tachometer to measure the rotations of the wheel of the pulley and strain gauge to measure the force pulling on the body of the pulley. The pulley, also referred to as “smart pulley”, can be implemented in many tethered swim training apparatuses of different arrangements. With the tachometer and strain gauge the power and other performance metrics can be calculated while a swimmer is using the apparatus. A load cell or similar can be used in place of a strain gauge. The sensors may be connected via wired or wireless communications to a computer (tablet, laptop, personal computer, server, or the like) for processing of the signals and display on an electronic display.

An apparatus and method for measuring a swimmer's speed and conveying the speed to the swimmer in real time includes a plurality of ultrasonic beacons each having a transducer configured to emit ultrasonic signals in a pool or other body of water within which the swimmer is swimming. A wearable, waterproof, ultrasonic receiver worn by the swimmer, receives the ultrasonic signals and generates corresponding signal data. The receiver's microcontroller captures and uses the signal data to calculate the swimmer's position and speed in real time, and conveys this information to a wearable, waterproof, user interface device worn by the swimmer, the user interface device including a near-eye display disposed on the swimmer's goggles.

A hydrotherapy apparatus (1) comprises a tank (10); a conveyer (30) with a conveyer frame (34) and drum (38) mounted within the tank (10), and an actuator (200) comprising: a guide (202) mounted on an end region of the conveyer frame (34), the guide (202) comprising a first portion (202a) and a second portion (202b) angled downwards with respect to, and closer to the drum (36) than, the first portion; a glider (204) arranged to be received by the guide (202); and an actuator shaft (208) arranged to move the glider (204). The conveyer (30) is arranged to be rotated around the axis of the drum (36) by the actuator shaft (208) moving the glider (204) along the guide (202). The hydrotherapy apparatus (1) may comprise a lifting arm (80) rotatably connected to the conveyer frame (32), at a position spaced from the drum (36), at a first end region of the lifting arm (80), and arranged to be driven by the actuator (200) so as to rotate the conveyer (30) further.

A hydrotherapy apparatus comprises a tank, the tank comprising a panel arranged to form a wall of the tank, and an inner frame arranged to have the panel mechanically fixed to an outer side thereof, without bonding, so as to form a watertight seal. The inner frame may comprise a lower portion in a base region of the tank and two struts extending upward therefrom. The tank may further comprise a lower fixing section arranged to be mechanically connected to an outer surface of the lower portion of the inner frame, with a lower edge region of the panel therebetween, and two side fixing sections extending upward and each arranged to be mechanically connected to an outer surface of a respective strut of the struts of the inner frame, with a respective side edge region of the panel therebetween.

The invention relates to a surfing installation (10, 10A, 10B) for generating a surfable wave (60), comprising an inclined ramp (50) to the upper end (51) of which water flows via a water inlet (46), which water is accelerated on the ramp (50) to a first flow speed, the lower end (52) of the ramp (50) leading into a region (30) having a lower second flow speed relative to the first flow speed, and a standing wave, in the flow direction, forming in the region (30) as a result of the water flowing at the first, faster flow speed striking the water flowing at the second, lower flow speed. A further functional area for the surfing installation (10) for one or more surfers (80) is achieved, according to the invention, in that at least two walls (506, 508) that define at least one flow channel (504) are arranged in the region of the water inlet (46) and/or of the ramp (50), which walls are movable in rotation and/or in translation, transversely to the flow direction of the water, by means of at least one drive (5046), in order to generate at least one traveling wave (60) that travels transversely to the flow direction.

This invention is a simple method to play a one-on-one underwater goal-scoring sport together with the pertinent field of play, the projectile and the goal apparatus. While underwater, one offensive player throws the projectile toward the underwater goal apparatus defended by a defending player who tries to tag out the offensive player before they can throw, or who tries to prevent the projectile from touching the goal area. Variations to the projectile and the goal apparatus are also described as options for use in the sport.

The invention provides for an apparatus for the throwing of bags comprising a first game piece and a second game piece, each including a play board and a boat board underneath the play board; a target hole on a rear end of each play board; the front of each play board is attached to the front of each boat board at an angle relative to the boat boards; the first game piece having a bow board at a rear end of the game piece; and the second game piece having a bow board on the front end of the game piece. The invention also provides for methods of playing bag toss in a body of water with the apparatus.

Automatic swimming analysis and nearly immediate feedback on a user device is disclosed. A sensor placed on a swimmer's waistline instantaneously measures data of the swim, allows to upload this data to a cloud system performing immediate analysis using algorithms. The cloud system provides feedback which helps determine proper (or improper) swimming techniques, comparing patterns to own past swims or to professional swimmers. The sensor enables stroke improvement with output including graphs, single numerical values, and detailed single-stroke data. The output provides both easy to understand metrics for amateur swimmers as well as more technical analysis options for advanced users. Metrics for amateurs can include swim symmetry analysis, speed consistency analysis, and stroke consistency analysis. More technical/detailed information includes comparison of strokes of each arm to the other, comparison of strokes made by left and right arms, mathematical analyses of strokes, and average, maximum, minimum, and instantaneous speeds.

The present invention relates to a floatable breathing device. The floatable breathing device provides includes a head unit, a snorkel, a plurality of receiving passageways, and an internal pathway. The head unit has buoyant properties and includes an ornamental shaped outer housing and an inner housing positioned within the outer housing, the inner housing forms a head receiving section, the head receiving section is provided between outer surfaces of the outer housing and is configured to be contoured to a human head. The snorkel connects to and extends from the head unit. The plurality of receiving passageways are disposed about the outer housing and receiving the snorkel, the snorkel extending through and exiting a portion of the head unit above a predetermined waterline extending along a periphery of a lower portion of the head unit thereof and identifies buoyancy of the head unit in water. The internal pathway positioned along a base of the outer housing and extending through a center section of the head receiving section of the head unit.

An aqua-resistance exercise device includes an elongate member, a strap, fasteners, and one or more fins. The elongate member includes an engagement portion, a shaft extending from the engagement portion, and a handle to be gripped by a user.
