An improved swim spa is described which has a tank having a head end and a foot end filled with water. A forward current is created by pumping equipment which directs the forward current from a head end of the tank, past a swimmer in the water to a foot end of the tank. The pumping equipment may be attached to a removable wall insert to which may be removed to allow easy repair and maintenance. The forward current allows the swimmer to swim in place. The width of the forward current is chosen to be at least twice its depth. A diverter at the foot end of the tank has a curved surface for redirecting the forward current toward the sidewalls and then back toward the head wall in a horizontal plane and downward and back toward the head wall in a vertical plane.

A mount device is disclosed for securing a swimming starting block to a floor. In at least one embodiment, the mount device provides an upper mount conduit engagable with the starting block and sized for at least partially extending into a receiver conduit in the floor. A lower mount conduit is positioned below the upper mount conduit and has an outer diameter or width sized for being completely positioned within the receiver conduit. An expansion bolt extends through respective substantially coaxially aligned bores of each of the upper mount conduit and the lower mount conduit, each of the bores having a diameter that is relatively larger than a diameter the bolt. Upon tightening the expansion bolt, the lower mount conduit is urged along an angled common axis toward the upper mount conduit, such that opposing long outside surfaces of the upper mount conduit and lower mount conduit are urged in opposite, substantially horizontal directions, creating a frictional engagement within the receiver conduit.

A flotation component, such as for a pull buoy, can be sized and shaped to be placed between the legs of a swimmer. The flotation component can include one or more features to assist in maintaining the flotation component in place while the swimmer is swimming. A pull buoy including the flotation component also can include an internally routed strap that assists in fastening the flotation component to at least one leg. A pull buoy including the flotation component can include a waist portion having a lateral diameter that decreases from one end to the opposite end.

The present development is a device that restrains an individual from swimming beyond a predetermined range. The device comprises a frame, at least one ballast unit, at least one tether line and a means to secure the swimmer to the tether line. The device is intended to be portable and easy to use while still providing a sturdy restraint.

A swim lane apparatus having one or more attachment or tethering devices. The one or more attachment or tethering devices are configured to couple or affix to a foundation of the pool. The swim lane apparatus has a first sidewall. The first sidewall is coupled to the one or more attachment or tethering devices. The first sidewall is configured to form a channel and direct a flow of water out of the channel when the flow of water enters the channel.

A liquid sealing actuator system enables use in a non-contact or low-friction manner. The system includes: an inner shaft having a first end; a hollow outer shaft having a first end that receives the first end of the inner shaft; at least one sealing ring positioned adjacent an internal surface of the hollow outer shaft, wherein the at least one sealing ring has an outer diameter that is less than an inner diameter of the outer shaft, thereby defining an annular seal gap; a mass attached to a distal end of either the inner shaft or the outer shaft; and a pressure source that injects a pressurised fluid into the hollow outer shaft, thereby applying a pressure against both the first end of the inner shaft and the at least one sealing ring that assists in lifting the mass; wherein the system is at least partially immersed in an external liquid such that the at least one sealing ring is submerged in the external liquid and a head of the external liquid above the at least one sealing ring defines a backpressure in the annular seal gap that opposes the pressure applied by the pressure source.

Bath for exercising, the bath containing substantially vertical wall portion, and a suitably configured bath bottom, from which extends an exercise base, wherein the bath bottom is formed so that the bath is the deepest in the area where the person lying on the exercise base reaches when moving her legs, the bath is lower in the area where she reaches when moving her arms, wherein the bath bottom is shaped so that in the top view it follows the trajectory of the user can reach when moving her limbs.
