Abstract: One embodiment of an extendable and retractable tennis racquet contains a stringed area 01, throat 02, and shank 03 as one integral member. The handle is comprised of a shank inside of a hollow handle 05. A spring or flexible means 07 connects the shank to the hollow handle. When the racquet is swung, the centrifugal force generated pulls on the head assembly. The shank slides outward telescopically, thereby increasing the length of the racquet. At the end of the racquet swing, the restoring force of the spring overcomes the diminishing centrifugal force, which pulls the shank back to its retracted position. Other embodiments are described and shown.
