Embodiments herein are directed to an aquatic exercising assembly. The aquatic exercising assembly includes a container having a liquid retention portion. The liquid retention portion includes a bottom wall, a pair of opposing sidewalls, and a pair of opposing end walls, a pedal assembly and a paddle assembly. The pedal assembly is rotatably coupled to the one of the pair of opposing end walls. The paddle assembly is coupled to each one of the pair of opposing sidewalls. The paddle assembly is movable between a rearward position and a forward position in a longitudinal direction. The pedal assembly is rotatably moved by a lower body movement of a user and the paddle assembly is moved by an upper body movement of the user.

Disclosed is a swimming assistance apparatus, which is worn on a user's both feet to provide the user with buoyancy, such that the user can float on water and swim in a good swimming style while repeatedly moving the waist from side to side like a fish, thereby reinforcing the user's waist muscles. Persons who have knee joint arthralgia or backache or persons who have disability in the lower body can use the swimming assistance apparatus for medical purposes, such as pain relief or treatment.

Systems and methods of analyzing a user's motion during a swimming session are described. One or more motions sensors can collect motion data of the user. A processor circuit can make motion analysis based on the motion data. The processor circuit can determine if the user's arm swing is a genuine swim stroke. The processor circuit can also determine whether the user is swimming or turning. The processor circuit can also classify the user's swim stroke style. The processor circuit can also determine the user's swim stroke phase. The processor circuit can also determine the user's stroke orbit consistency.

A variety of improvements to portable electronic devices are disclosed, particularly electronic devices designed for use in and around water. The improvements include a more secure interface jack, improved waterproofing techniques, improved battery stability, and improved device functionality. One or more of the disclosed improvements may be incorporated into a variety of portable electronic devices.

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.

A lung exercise apparatus and method with an enclosure, with an inside, an outside and an open top, configured to hold a liquid of a first density. An additive to the liquid that increases the first density such that a person in the liquid is more buoyant. Weight removably connectable with the person such that a person in the enclosure is held vertical in the enclosure and partially immersed in the liquid below a surface of the liquid and with some of a person's body above the surface of the liquid. And a harness that is removably connectable with the person to hold some of the person's body above the surface of the liquid where lungs in a person's body are below the surface of the liquid.

Proposed are an aquatic exercise apparatus and a method for exercising aimed at improving mobility of a user by exercising in water. The apparatus consists of base support and a balance board, which is connected to the base support via a resilient body that allows tilting of the balance board in any direction and a mechanism that provides free rotation of the balance board. Exercising in water allow people with mobility deficits to perform exercises without a fear of falling, decreasing pain, and improving cardiovascular return.

A floatation device is provided. In some embodiments, a floatation device is provided, comprising an inflatable ring composed of a transparent material, wherein the inflatable ring includes: an outer air chamber having a first valve for inflating the outer air chamber; an inner air chamber having a second valve for inflating the inner air chamber, wherein the outer air chamber and the inner air chamber are not in communication; a cut through the outer air chamber and the inner air chamber of the inflatable ring that forms opposing ends of the inflatable ring; and a plurality of fasteners placed on a top surface and a bottom surface of the outer or inner air chamber for detachably connecting the opposing ends of the inflatable ring.

A wave pool and wave generating mechanism are disclosed. The wave pool includes a bathymetry that includes a dynamically shapeable reef along a length or circumference of a channel that defines the wave pool. The wave generating mechanism includes a foil that has a shape for bi-directionality based on an adjustment of a yaw angle of the foil. The foil can be further controlled to increase or decrease certain surface areas or other angles of interacting with water in the wave pool.
