ABSTRACT:
FIELD OF THE PRESENT INVENTION
The present invention generally relates to machines and methods for exercising and measuring the strength of muscles of the human body. The muscles involved can be any of the muscles of the human body such as, for example, lumbar, abdominal, arm, neck, biceps, and other muscles and therefore the present invention is not limited to any specific muscles. The machine and method of the present invention are of the type that typically involve a movement arm that is movable against a resistance, preferably a weight resistance. The subject exerts the muscles whose strength is to be measured, to move a portion of the subject's body against the resistance.
OBJECTS OF THE PRESENT INVENTION
An object of the present invention is to provide novel and improved methods and apparatus for measuring the strength of muscles of the human body. Included herein are such methods and apparatus which accurately measure muscle strength in a safe and effective manner.
Another object of the present invention is to provide novel and improved methods and apparatus of measuring the static and dynamic strength of muscles of the human body.
Another object of the present invention is to provide novel method and apparatus which facilitate the accurate measurement and display of the strength of a subject's muscles during an exercise of the muscles.
SUMMARY OF THE PRESENT INVENTION
In summary the present invention provides method and apparatus for measuring the strength of a subject's muscles in conjunction with a computer which receives information from an exercise machine when the subject exerts the muscles against a resistance included in the machine. In one mode of the machine and method, the subject exerts forces against a resistance which is fixed against movement. A force measuring device such as a strain gauge responds to the forces and sends information to a computer which processes the information and makes calculations for displaying the strength of the muscles on a display screen. In another mode of the machine and method, the resistance is free to move in response to the subject exerting forces against the resistance. Here again a force measuring device such as a strain gauge will measure the force applied to the resistance and feed this information to the computer which will process the information for display on the screen. In addition an angle measuring device is included in the machine for measuring the angle of the subject's body part acting against the resistance. The information is fed into the computer thus allowing the strength of the subject's muscles to be displayed on a screen with respect to different angular positions of the body part.
