Development of the Cylindrical Grip Force Measuring Equipment

The value of grip force is widely used for the brawn measurement in the physical strength examination because of its easy measurement. However, by use of the grip dynamometer being on the market, force is measured to only one direction, so it is doubtful whether various kinds of brawn can be measured. For example, the grip force to tennis racket seems to be different from the force measured by the grip dynamometer. Therefore, we developed the equipment to measure brawn gripping the cylindrical bject like tennis racket grip. Then we examined characteristics of both conven ional grip dynamometer and the newly developed equipment. As the result, for the ormer, grip width has an influence slightly on grip force, but, for the latter, grip iameter affects strongly as the human sense feels.
