ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to a game racket, and more particularly to a game racket having means to show the body condition of an exerciser using the game racket.
BACKGROUND OF THE INVENTION
The exercise can bring about changes in the body physiology of a person engaging in the exercise. For this reason, the moderate exercise is often beneficial to the health of an exerciser. If the exercise is done excessively, the exercise becomes in itself hazardous to the health of the exerciser. The conventional game rackets are not provided with a device for monitoring the body condition of an exerciser. As a result, the exerciser is often unaware of the need to adjust the pace of exercise to minimize the risk of the danger resulting from the excessive exercise.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a game racket capable of monitoring the state of body of a person doing the exercise with the game racket.
In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by a game racket comprising a frame and a handle. The handle is provided in the grip thereof with a sensor for detecting the changes in the body physiology of an exerciser doing the exercise by using the game racket. The data are exhibited in a display to remind the exerciser of the need to adjust the pace of the exercise.
