ABSTRACT
Skeletal muscles are able to move body segments with respect to each other against internal and external
resistances. Muscle components can shorten dynamically, statically retain their length, or be lengthened.
Various methods and techniques are available for assessing muscular strength. The engineering appli-
cation of data on available body strength requires the determination of whether minimal or maximal
exertions, static or dynamic, are critical. Data on body strength are available for the design of tools,
equipment, and work tasks.
