Nutritional status and physical fitness of Polish miners and steel workers

Summary The nutritional status of 690 miners and 604 steel workers was determined. Their physical fitness was estimated by an indirect method using the Astrand Rhyming nomogram. The nutritional status parameters indicated an increase in weight in relation to increasing age: 57% of the subjects were overweight. Over 70% were current smokers. The mean value for V O₂max was 2.8 ± 0.51/min / 38 ± 7 ml/kg per min. The high percentage of subjects (Polish miners and steel workers) who eat too much, are overweight, smoke and who have a low physical-activity level during their leisure time demonstrates the risk for coronary heart disease.This work was supported by Poland's Central Program (C.P.B.R. 11.11.65) and by the Ministry of Health (6/MZ-IX/86-8)
