A stability ball inflation and deflation system includes a stability ball with a bore, and a plug within the bore walls. An air-control module engaged within the axial channel of the plug selectively allows air to pass in one or both directions. The air-control module includes a one-way air valve, and a cap releasably sealable to the plug. An airway extending from the one-way valve provides fluid communication with the interior of the stability ball. An inflator adapted to engage the one-way air valve may be removably coupled to the air valve, and provide air passages to direct air from a pressurized air cartridge into the stability ball.

1. A stability ball inflation and deflation system, comprising: a stability ball, including a bore extending radially into the interior of the ball;an open-ended plug within the bore, with a proximal end aligned towards the surface of the ball, and a distal end extending into the interior of the ball, the plug including an axial channel extending therethrough; an air-control module, engaged within the axial channel of the plug and including a one-way air valve and a cap releasably sealable to the plug, the air-control module including an airway extending from the one-way valve axially therethrough and providing fluid communication with the interior of the stability ball;an inflator adapted to engage the one-way air valve, wherein the inflator includes air passages to direct an airflow from a pressurized air cartridge;wherein the air-control module is configured to be manipulated between a first position in which the cap forms an air-tight seal with the proximal end of the plug and a second position the air-tight seal is broken and fluid communication between the interior of the ball and the ambient is provided through the plug and air-control module;wherein the air-control module is threadedly engaged with the plug, and is repositionable between the first and second positions by inward and outward threading of the air-control module with respect to the plug; andwherein the fluid communication between the interior of the ball and the ambient in the second position is provided by a groove extending axially through threads that engage the air-control module and plug. 2. The stability ball inflation system of claim 1, wherein the groove is provided in the threads of the air-control module. 3. The stability ball inflation system of claim 1, wherein: the air-tight seal is provided by an o-ring mounted to at least one of the plug and the air-control module. 4. The stability ball inflation system of claim 1, further comprising: two rigid and diametrically opposed tabs extending axially outward from the outer surface of the cap. 5. The stability ball inflation system of claim 4, wherein: the plug and air-control module, including the tabs, are completely recessed with respect to the outer surface of the ball at least when the air-control module is in the first position. 6. The stability ball inflation system of claim 1, further comprising: a retainer maintaining a connection between the air-control module and the plug. 7. The stability ball inflation system of claim 6, wherein: the retainer comprises a stem on the air-control module extending through a narrow portion of the axial channel, and a stopper at the end of the stem and positioned axially inward of the narrow portion of the axial channel of the plug, the stopper having a greater diameter than the narrow portion of the axial channel of the plug. 8. The stability ball inflation system of claim 1, further comprising: the inflator includes a valve coupling, wherein the valve coupling engages the one-way air valve to allow airflow into the ball. 9. The stability ball inflation system of claim 1, wherein: the inflator includes a flow controller, wherein the flow controller adjusts the airflow volume passing to the valve. 10. The stability ball inflation system of claim 9, wherein: the inflator includes a cartridge receiver to connect to the pressurized air cartridge. 11. The stability ball inflation system of claim 10, wherein: the pressurized air cartridge is a CO2 cartridge. 12. A method for selectively inflating or deflating a stability ball, the method comprising the steps of: providing a stability ball, the ball comprising:an axial channel defined by a plug extending therethrough;a cap releasably sealable to the plug;a one-way air valve protruding from the exterior of the cap; andan airway extending from the one-way valve axially therethrough and providing fluid communication with the interior of the stability ball;inflating the ball by manipulating the cap to a first position to create an air-tight seal, and coupling a valve connector in fluid communication with a pressurized air cartridge to the one-way valve;deflating the ball by manipulating the cap to a second position and breaking air-tight seal, and causing fluid communication between the interior of the ball and the ambient through the plug and cap;wherein the step of manipulating the cap is accomplished by rotating two rigid and diametrically opposed tabs extending axially outward from the outer surface of the cap, thereby moving the cap laterally with respect to the plug, wherein the cap is threadedly engaged with the core of the plug; andfurther providing grooves extending axially through threads that engage the cap and plug, allowing fluid communication between the interior of the ball and the ambient in the second position. 13. The method of claim 12, further comprising: adjusting the air flow volume from the pressurized air cartridge to the interior of the ball by manipulating a flow controller in fluid communication with the valve connector and the pressurized air cartridge. 14. The method of claim 12, wherein: the airway extends through a retainer maintaining a connection between the cap and the plug.
