Following medical and dental examinations these workers were studied in laboratories specially set up in their isolated habitats. Maximal oxygen uptake, body composition am anthropometric characteristics were measured. The physiological work load am the energy expenditure during actual work were assessed by measuring oxygen uptake and cardiac frequency.
