Abstract

The physical work capacity is studied in representatives of 3 professions with decreased motor activity and neuropsychic stress: managers in industry (20), railway controllers (41) and machine-builders (107). The dependence of the physical work capacity on the age, type of work, physical activity during free time, and other biometric and individual characteristics on the examined persons were studied. The physical working capacity was measured in standard laboratory conditions by bicycle ergometer [correction of veloergometer] Lano at submaximal rates of loading 50, 100 and 150 watt with duration 2 min each and velocity of pedalling 60 r/min. The maximal working capacity (MWC) was measured directly by continuous loading increase to refusal. The results pointed out ineffective reaction of the cardiovascular system at dosage of physical effort (increase of the "normative" values of the pulse rate for respective loading with 5 to 15 beats/min with all examined groups). The aerobic capacity level is under the average, as most unfavourable are its values in the managers from the industry, followed by the railway controllers and machine-builders. Hypodynamic during work, combined with low physical activity during free time, are basic risk factors for the maximal working capacity and the cardio-vascular system. There is a dependence of the aerobic capacity on some individual characteristics (age, body weight, pulse frequency and blood pressure at rest, etc.).
