[Physiological characteristics of the health status of workers performing physical labor]

It was examined the physical fitness of 165 male laborer with a special respect to their physical performance. The research covered other factors, as well such as the somatic and circulatory parameters, the maximal oxygen uptake estimated by Astrand, i.e. the aerobe metabolism, the activity and the fitness of the nervous system, the possible proteinuria following loading, the health condition of the examined persons and also certain other factors concerning their way of life. On the basis of the results, the authors established that with the major share of the examined labourers (nine percent of them) it was impossible to carry out the exercises because of contraindication, and in the case of 46 percent the exercises had to be interrupted because of occurring of certain symptoms and exhaustion. The physical performance was unfavourably affected by the fact that the relative majority of the examined persons are overweight, and the lungs function, especially the MVV-value does not reach the predicted level. Only 32 percent has the optimal body weight, while 20-26 percent is overweight. The MVV-value is under the predicted level in the case of 67-76 percent. The estimated relative aerobe capacity reached 84-86 percent of the predicted value with those whose physical performance is moderate. The authors evaluated the accomplished examinations individually as well and summarized them in records of examination. The records were distributed among the factory medical consultants who applied them effectively in the health provision of the examined persons.
