[Various aspects of applied biochemical studies in aviation medicine]

This paper presents a review of Soviet and foreign publications (1955-1985) containing biochemical data obtained during real and simulated aircraft flights. The paper discusses the results accumulated before and after flights of varying duration, when performing tasks of different complexity and by pilots with different professional skills. Special attention is given to the studies in which biochemical parameters have been used as a measure of recovery and professional adequacy. Biochemical results are also presented which may help detect young people susceptible to hypertensive disease and ischemic heart disease as well as prevent and modify these pathologies and fatigue.
