A stringed racket includes at least one string constituting the central stringed area of the racket with higher tensile elastic modulus, and a peripheral stringed area with sections of the string having lower tensile elastic modulus. Another stringed racket includes at least one string constituting the central stringed area of the racket with lower tensile elastic modulus and a peripheral stringed area with sections of the string having higher tensile elastic modulus.
