摘要
An apparatus for measuring physical strength by dynamically measuring the instantaneous power of a nonrepetitive muscular force as, for example, the force exerted by a leg extension, on the basis of a power theory and, consequently, the instantaneous power generated by a dynamic, nonrepetitive multi-articular movement such as a vertical jump. The power produced by a leg extension is calculated from the maximum speed V.sub. max of the foot plate and its output time T.sub.max. An apparatus for such measurement includes a base frame; a guide section that extends in the same direction as the base frame; a foot section that slides along the guide section so that its sliding angle is variable; a measuring unit that measures sliding conditions of the foot section; a display unit that displays, visually or aurally, various data on the leg extension of the subject; and a processor means for calculating the power generated by the leg extending force.
