Achieving two consecutive BCS National Championship titles is a big deal. And for University of Alabama's football team Crimson Tide, it means major facility improvements that include a $9 million, 37,000 square-foot weight room, hydrotherapy pools equipped with waterfalls, and even anti-gravity treadmills for a quick recovery from injuries.

Jeff Allen, UA Assistant Athletic Director for Sports Medicine, said that the program purchased the anti-gravity trainer a year ago to help current NFL running back Eddie Lacy recover from a toe injury, reported.

"We've had this for a year now. We purchased it when Eddie Lacy had his toe injury," Allen explained.

"What this allows us to do is take a guy and run them at a lower percentage of their body weight. Theoretically, if you weigh 200 pounds, I can put you in here and set this to run you at what it would feel like to run at 50 pounds."

Manufacturers of this futuristic training device claim professional athletes as well as Olympians have felt its benefits that include a shortened rehab time. Woodway Treadmills even says that its G-Trainer can help ease amputee patients into a new prosthetic limb.

The patient is placed inside a bubble chamber that surrounds his or her lower body but exposes the upper body. Pressurized air lifts the user up, making him or her feel around 20 percent lighter. Those who have used it compare the feeling to running on water or floating.

Although you shouldn't expect to see any anti-gravity treadmills at your local gym anytime soon, technological advancements like this are a welcomed development to medical and health professionals.
