Uporaba delovnim razmeram primerne osebne varovalne opreme lahko zmanjša težavnost dela in obremenitve gozdnega delavca. Z namenom ugotavljanja razlik med sistemi varovalnih oblačil (poletni, prehodni, zimski) se je izvedla raziskava na kolesnem ergometru, kjer se je merilo več psihofizičnih kazalnikov. Raziskava je pokazala, da pred in po testu ni značilnih razlik v koncentraciji laktata v krvi in v temperaturi v ušesu, medtem ko je razlika značilna v telesni masi, obstaja pa tudi značilna povezava med trajanjem testa in porabo energije. Upor ergometra (W) značilno povečuje vrednosti vseh psihofizičnih kazalnikov, ki smo jih lahko kontinuirano merili preko testov. Pri meritvah srčnega utripa obstajajo značilne razlike med vsemi sistemi oblačil, razen med poletnim in prehodnim, pri električni prevodnosti kože ni razlik med prehodnim in zimskim sistemom ter med poletnim in zimskim. Razlike med sistemi oblačil obstajajo tudi pri temperaturi kože, razen med prehodnim in zimskim sistemom, prav tako pa niso zaznali značilnih razlik med sistemi pri meritvah hitrosti dihanja. Kljub izvedbi poskusa samo na eni osebi, rezultati prikazujejo uporabnost izbranih kazalnikov za meritve psihofizičnih obremenitev ter dokazujejo, da na obremenitve gozdnega delavca potencialno vpliva tudi uporaba varovalnih oblačil.

• Title: Influence of use of forestry personal protective equipment on psychophysical load

Abstract

Use of proper personal protective equipment, can reduce workload of forestry workers, depends on working conditions. In order to identify differences between protective clothing systems (summer, transitional, winter), a study using a cycling-ergometer measuring several psychophysical indexes was conducted. The results show no differences in the amount of lactic acid in blood, or the temperature measured in the individual´s ear prior and after the trial, however significant differences occur in body mass. Moreover, there is relation between the duration of the test and consumption of energy. The ergometer´s resistance (measured in Watts) caused significant differences to the measured indexes. There are significant differences between the heart rate measurements while using different types of clothes, except summer and transitional system. However, there are no differences between the results measuring skin´s conductivity in transitional and winter systems, nor between the summer and winter equipment. Differences between the systems were measured also in skin temperature, while using summer and winter equipment, and by using summer and transitional equipment. Even so, there were no significant differences between the equipment systems while evaluating breathing frequency.
