Patent ID: 7442150

Claim:
Leg strength measuring apparatus comprising: at least one footplate configured to receive and support a person whose leg strength is to be measured as the person stands on the footplate; a load sensor operable to detect loads applied to the footplate; load comparison apparatus operable to compare a plurality of loads detected by the load sensor as the person flexes and bends at the person's knees while the person is standing on the footplate, wherein said load comparison apparatus is further operable to store data corresponding to a maximum detected load among the plurality of detected loads; weight detection apparatus operable to store data corresponding to a load detected by the load sensor when the person is standing stationary on the footplate; and leg strength calculation apparatus operable to calculate the person's leg strength based on a comparison of the data corresponding to the maximum detected load and the data corresponding to the stationary load, and corresponding to a subtraction of the stationary load from the maximum detected load.
