“…As many as 82 % of the 50 surveyed engine drivers from a random sample are overweight or obese [6] regarding the numerical value of the body mass index -BMI (BMI ≥ 25). The studies carried out during 2011 in Slovenia [9] targeting 245 employees at the railways indicate 66,9 % overweight or obese workers, with no significant differences between the two groups of workers regarding the nature of their work (white or blue-collar workers).…”

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 multipurpose 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.

“…Our own previous research [7] confirms that after the age of 30, the percentage of obese and overweight engine drivers (BMI ≥ 25) increases significantly (after the age of 30, the BMI percentage is in the range between 72.3% and 92.31%, which depends on the age group). The studies carried out during 2011 in Slovenia [8], targeting 245 employees at the railways, indicate 66.9% of overweight or obese workers, with no significant differences between the two groups of workers regarding the nature of their work (white or blue-collar workers). In a study on 118 subjects, the influence of BMI on seat comfort was studied [9].…”

The paper presents a simpler and more precise model of lumbar moment prediction based on single linear, or multiple linear regression with two predictors. The body mass index (BMI) as the predictor contains two of the most important static anthropometric measures, height and mass, whose separated role in lumbar moment prediction, as well as their mutual relations, have not been sufficiently investigated. This study analysed mass, height, age and BMI as lumbar moment predictors, on a sample of 50 Croatian male engine drivers. Two prediction models were compared: (1) multiple linear regression prediction with mass and height as predictors; (2) single linear regression with mass as the only predictor. Results confirmed the multiple regression model as the best one (R2= 0.9015 with standard error of prediction 1.26), having the mass of the best predictor. Surprisingly, the single regression model with mass as predictor explained only 3.6% of lumbar moment variance less than multiple regression model, with related standard error of prediction 1.46 (mean percentage value of the relative error was only 0.8% higher than at multiple regression model). The obtained findings suggest high prediction potential of mass and height that should be verified on various subject samples.

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
