Elbow Relief in a Tennis Ball

Dunlop has introduced a tennis ball called the "Abzorber" to help prevent tennis elbow. The new ball reduces shock on the arm by up to 15 percent, compared to other balls, Dunlop says. A standard-size tennis ball, the Abzorber is endorsed by the American Institute of Orthopaedic and Sports Medicine. A can of three balls sells for $3.49. www.dunlopsports.com
