Cavitated Water Training/Exercise Ball

Abstract

A device and method for enhancing swimming exercises which can be used with the swimmer's legs, hands and head. The device can be a closed cell EVA foam sphere having opposite sides formed into concave cavities. The cavities permit a swimmer to position the device between his / her knees and against which the swimmer must apply leg-closing pressure. This causes the swimmer to maintain streamline during the entire pulling phase of the arm movement of the swimming stroke. With the device positioned at the same location, breaststroke kick training can also be enhanced as it causes the swimmer to apply pressure to maintain proper knee distance during kicking. Alternatively, the device can be held in one hand while the other hand is used to implement the particular swim stroke, and the device can be exchanged easily to the other hand. The device can also be placed under the chin during swimming exercises.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates generally to exercise devices and, more particularly, to a floatable device and method which can be used with the hands, legs and head to enhance swimming exercises.[0002]Kickboards are well-known water exercise devices that can be used for a variety of water training exercises. Its most recognized use is for a swimmer to develop his / her kicking style as the user holds on to the kickboard with both hands. However, as can be appreciated, with both hands holding the kickboard, any upper body and / or arm movement is prevented.[0003]Another conventional swimming training device is known as a “pull buoy” which comprises a figure-eight closed cell foam that is placed between a swimmer's thighs or ankles. The pull buoy acts as a float to hold the swimmers legs in a prone position, thereby negating the need for the swimmer to kick. As a result, the swimmer can then tone or develop his / her upper body, viz., the arm stroke.[0004]Ho...

AI Technical Summary

Benefits of technology

This patent describes a water exercise device made of a buoyant sphere with concave cavities on its sides. The device can be used to enhance a swimmer's workout by positioning the concave cavity against the swimmer's knee or chin and applying pressure to close the legs or arms during swimming exercise. The technical effect is to provide a better workout experience for swimmers by improving their efficiency and comfort during exercise sessions.

Problems solved by technology

However, many of these water devices are either “over-buoyant” or “under-buoyant.” In particular, where a water device is over-buoyant, the swimmer experiences additional and unnatural pressure towards the water surface while using the water device and, as such, the swimmer alters his / her proper alignment in the water to compensate.

Conversely, where a water device is under-buoyant, this results in an undesirable “pull down” on the swimmer while using the water device, again, requiring the swimmer to his / her proper alignment in the water to compensate.
