Abstract
V letu 2011 je bila opravljena raziskava o težavnosti dela pri klasičnem in strojnem načinu sečnje in spravila lesa. Raziskovalni objekti so se nahajali na območju GGO Kočevje v gozdni združbi Abieti-Fagetum. Cilj diplomske naloge je bil ugotoviti težavnost dela pri klasičnem in strojnem načinu sečnje in spravilu lesa ter ugotovljeno težavnost primerjati z veljavnimi dopustnimi mejami. Težavnost dela so ugotavljali z meritvami srčnega utripa (pulz) na 4 delavcih: sekač, traktorist, voznik stroja za sečnjo in voznik stroja za spravilo lesa. Poleg meritev srčnega utripa, so istočasno delali časovno študijo, s pomočjo katere so kasneje izračunali težavnost dela po posameznih delovnih postopkih. Izračunali so različne kazalnike težavnosti dela: povprečni pulz med delom, delovni pulz, relativni delovni pulz in modelno dnevno obremenitev. Sečnja z motorno žago in spravilo s traktorjem se je izkazalo za težavnejše od strojne sečnje in spravila lesa. Veljavno dopustno mejo povprečnega delovnega pulza (razlika med pulzom med delom in izhodiščnim pulzom), ki znaša 35 u/min sta presegla sekač (53 u/min) in traktorist (42 u/min). Delo voznikov strojev za sečnjo in spravilo lesa pa se je izkazalo kot fizično manj naporno delo, izračunan povprečni delovni pulz voznika stroja za sečnjo znaša 16 u/min, voznika stroja za spravilo pa 9 u/min.

Abstract:
In 2011 a research was performed in order to obtain information about the physiological demands of forest work by felling with chain saw, skidding with cable skidder and by mechanical logging with cut to length method. The research objects were located within the GGO Kočevje area in the Abieti-Fagetum vegetation community. The objective of research was to determine the physiological strain of the standard and mechanical logging and to compare the results with valid admissible standards. The physiological strain was determined by measuring the heart rates in four workers: wood cutter, tractor driver, harvester driver and forwarder driver. In addition to the heart rate measuring, a simultaneous time study was conducted, by which the physiological strain of work in individual processes had later been calculated. Various indicators of work difficulty were calculated: average work heart rate, work heart rate, heart rate reserve and modelled eight-our physiological strain. The standard logging has proved to be the more demanding one. The valid admissible work heart rate (the differential between the baseline heart rate and heart rate during the working process) which stands at 35 bpm was exceeded by two workers: the wood cutter (53 bpm) and the tractor driver (42 bpm). The harvester and forwarder driversć work had proved to be less physiologically demanding. The calculated average work heart rate of the harvester driver is 16 bpm and the forwarder driver 9 bpm.
