[Characteristics of the physiological functions in the operators of foundry transfer lines in the course of the work day and week]. / Osobennosti fiziologicheskikh funktsii operatorov avtomaticheskikh liteinykh linii v techenie rabochego dnia i nedeli.

The correlation analysis covered the state of the cardiovascular, hemodynamic, thermoregulatory, vegetative nervous systems, the characteristics of strength, endurance, attention, readiness to action among operators of transfer foundry lines during working days and weeks. It was shown that the main physiologic changes occurred at the initial stage, i. e., on the first day before the dinner break. To the end of the working week correlational links were established among temperature, arterial pressure, characteristics of strength, endurance, the time necessary for response and attention, thus higher intensity of the thermoregulatory system functioning being evidenced.
