A gyro ball is a novel exercise device. Proponents claim that the gyro ball, sold by companies under names such as Powerball, GyroBall and Gyro Ball, can benefit you in a number of ways. You can use it to sculpt or strengthen wrists, hands, forearms and shoulders. People with conditions such as carpal tunnel syndrome, arthritis and wrist injuries can use it for rehabilitation. As of publication date, there is no research to validate these claims, although the gyro ball operates as an isometric resistance device, which are proven strengthening tools.
How it Works
A gyro ball is about the size of a tennis ball. It has a rotor in the center. When it is activated, the ball starts to rotate. Most have LED elements embedded, so they light up as well. Some gyro balls rotate fast enough to produce 45 lbs. of resistance. One description of a gyro ball, from the Powerballs website, states, "It literally comes alive, thrashing and jerking..." You control the ball by fighting its resistance, just as you would do isometrics against a wall or the floor or an opposite limb.
Potential Benefits
Gyro ball manufacturers tout its ability to strengthen and tone your arms, shoulders, wrists and hands in the same way as dumbbell curls. Setting the gyro ball at 13,000 rpm and controlling it for 30 to 40 seconds gives you "a muscle burn of monumental proportions," according to the Powerballs website. Gyro balls can be set between 1 lb. of resistance and 40 lbs., making it adjustable for all types of people and conditions. At lower speeds, it can be used for rehab purposes by generating a very small amount of resistance.
Target Markets
In addition to weightlifters and people undergoing rehab, manufacturers recommend gyro balls for specific sports such as baseball, basketball, golf and tennis. Musicians can use gyro balls to increase strength, coordination and dexterity in their hands and wrists. Computer users and anyone else who use repetitive movements can relax the hands and wrists by using a gyro ball for one to two minutes. The gyro ball might also be useful for older people who want to maintain movement and coordination in their hands and wrists.
Considerations
If you are rehabbing an injury, consult your doctor before using a gyro ball or any other exercise device. When you use a gyro ball, don't touch the rotor, drop it or put liquid into the rotor. You can find entry level gyro balls that reach top speeds of about 9,000 rpm with 35 lbs. of resistance and and high-end models that reach close to 15,000 rpm and have a resistance level of 45 lbs.
