RESUMEN
The routine protocol of general and neurological examinations and some special questionnaires were used to examine physical activity (FA) and physical working capacity (FWC) in a random population from one of the Moscow districts which included 1200 persons (males and females aged 30-64 years). The majority of the examinees were those who had slight and moderate exercises, mainly sitting work, did few or no physical exercises. The proportion of persons with low physical activity increased with age both among males and females. The ratios generally remained despite the presence of early signs of abnormal blood supply. Bicycle ergometer testings showed a significant reduction in the physical working capacity of the patients with abnormal brain blood supply, in a greater extent, in arterial hypertension. Decreased functional activity and functional working capacity may regarded as one of the risk factors for cerebrovascular disorders, in arterial hypertension in particular, and should be borne in mind in implementing preventive measures.
