Physiological Criteria and Procedures for Determining Work Fatigue (O Fiziologicheskikh Friteriyakh i Metodike Opredeleniya Tyazhesti Raboty),
Abstract
Among the physiological criteria and methods for determining work fatigue, which have taken a firm place in labor physiology, are those of the amount of external mechanical work expressed in kilogram-meters and energy consumption measured by the amount of consumed oxygen or amount of calories expended. This report discusses more accurate means of determining work fatigue, for the above criteria are applicable only for those forms of labor in which a large group of muscles are used. The method for studying work fatigue discussed here is based on the similarity and differences of varied types and forms of work. We present data concerning the indicators and methods for measuring functional stress on the indicated systems during work and the minimum and maximum possible values of this stress. The two kinds of fatigue primarly dealt with are nervous tension and muscular strain. Physical strain is measured by readings of pulse rate at various times during the work day. Fatigue for various types of professional labor can thus be established by the degree of functional stress on the various sytems of the organism. (Author)
