Original scientific paper Frequently used commands on the locomotive or railcar control panel need to be arranged mainly within the normal reach of the arm, using multi-purpose controllers for serving several important and frequently used functions by one hand, whenever possible. From the measured anthropometric measures in the central 90 % from the sufficient and random sample of 50 engine drivers the range of normal and maximal reach of arm has been defined using statistical methods for the entire population in Croatia. The ranges of statistical anthrompometric measures of the engine drivers are the constitutional factors from the group "human factor", and according to Fuller TCI model "task requirement -driver's capability" affect the difficulty of the task during driving. The correlation dependence of lumbar moment Ml on the index of mass BMI has been proven in the hypothetically most unfavourable statistical seating working position, and based on the really measured statistical anthropometric measures.

Iz izmjerenih antropomjera u središnjih 90 % od dovoljnog i slučajnog uzorka od 50 strojovođa statističkim metodama definiran je raspon normalnog i maksimalnog dosega ruku za cijelu populaciju u RH. Rasponi statičkih antropomjera strojovođa su konstitucijski čimbenici iz grupe "ljudskog faktora", a prema Fullerovom TCI modelu "zahtjev zadaće-sposobnost vozača" utječu na težinu zadaće tijekom vožnje. Dokazana je korelacijska ovisnost lumbalnog momenta Ml o indeksu tjelesne mase ITM u hipotetski najnepovoljnijem statičkom sjedećem radnom položaju, a na temelju stvarno izmjerenih statičkih antropomjera.Ključne riječi: antropomjere; ljudski faktor; normalni i maksimalni doseg ruku; središnjih 90 %; strojovođe; težina zadaće
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
