Dynamometry

 

measurement of the strength of separate human muscle groups with the aid of special devices called medical dynamometers. Hand dynamometers are used to measure the strength of the muscles that flex the fingers, a posture dynamometer is used to measure the strength of the muscles that hold the body erect (“posture” strength), and so on. Dynamometric indexes can be expressed in absolute values (kilograms-force) and in relative values, for example, with respect to the mass (weight) of the human body. The data of dynamometry are used in anthropometry, in the selection of a trade, in the physiology and hygiene of labor and sports, and in medicine. They are also used as an additional factor in evaluating the degree of human physical development.
