[Physical fitness of students of various vocational schools].

Average values of various anthropometric and physiologic indices have been obtained for a representative group of 485 pupils of vocational schools, aged 14-18. The mean values of height (almost 175 cm), weight (66 kg) and Vo2 max (3.25 lo2/min or 48.3 ml/kg x min. or 59.2 ml/kg FFB/min.) were somewhat higher than average product in terms of physical fitness. According to estimates for ergonomics, these investigations confirmed that Polish Anthropometric Standards could be applied to set up new workplaces using upper limits of these standards. The optimum level of average workload in the case of new workers is somewhat above 5.0 kcal/min. During pre-employment and periodical medical examinations of juveniles we can use Vitalograph spirometer because predicted values of VFC and FEV1.0 for this spirometer have been calculated.
