    摘要: A swing analyzing apparatus includes: a three-axis acceleration sensor attached to a tennis racket, for measuring accelerations in the directions of three axes when a swing for hitting a tennis ball is taken with the tennis racket; a three-axis gyro sensor attached to the tennis racket, for measuring angular speeds about the three axes; and an analyzing device. The analyzing device has a receiving function to receive data regarding the accelerations and the angular speeds from the three-axis acceleration sensor and the three-axis gyro sensor; a coordinate axis conversion function to convert relative coordinate axes that are the three axes for the accelerations into absolute coordinate axes on the basis of the angular speeds; and a calculation function to calculate an index of the swing on the basis of accelerations resulting from the coordinate axis conversion.

    摘要: Disclosed is a two-piece golf ball comprising a core made of a rubber composition containing a base rubber, a co-crosslinking agent and an organic peroxide, and a cover. The core of the golf ball contains 20 to 30 parts by weight of the co-crosslinking agent based on 100 parts by weight of the base rubber. A hardness of the core, measured by a JIS-C type hardness tester, is within a range from 70 to 80 at any part from the center to the surface and a difference in hardness at any part is not more than 5. An amount of compression deformation of the core formed between initial loading (10 kg) and final loading (130 kg) is 3.1 to 3.8 mm.
