QUANTITATIVE ESTIMATION OF THE FUNCTIONAL CONDITION OF THE SKI ORGANISM
the article provides an extensive review of methods for assessing the functional state of the human body, describes the more well-known methods. The article describes the method of the critical frequency of light flashings (CFSM), which is an indicator of changes in such properties of the nervous system as excita¬bility, lability, strength and mobility of nervous processes. In addition to CFFF as an integral psychophysio¬logical indicator for the diagnosis of fatigue, it has been proposed to use the differential sensitivity of vision to the frequency of light flashes (DFSM), which refers to the ability of the visual analyzer to distinguish two frequencies that are different from each other.
