Modelling the effects of personal protective clothing properties on the increase of metabolic rate

Type: article
Abstract: Many of the PPC garments studied in this thesis are heavy, bulky and made \nup of multiple layers and stiff fabric as evident from the previous chapters. \nHowever it has proved hard to isolate completely the effect of a single \ngarment property on the overall increased energy cost when wearing the \nactual PPC. An alternative approach to studying the individual contributors \nto metabolic effects of PPC is by studying them combined. \n \nIn this chapter, data on a number of PPC properties will be collected and \nanalysed using Pearson’s r and multiple regression, to determine the \nrelative importance of these properties on recorded metabolic rate \nincreases. This technique has been used to study other complex \ninteractions before (Havenith et al. 1995). For this purpose, relevant \npredictive parameters of the clothing tested in Chapter 3 will be determined \n(weight distribution, insulation, bulk, stiffness) and the previously observed \nincreases in metabolic rate analysed in relation to these predictors. \n \nAttempts will be made to use simple and non-destructive methods to \ndetermine the parameters, in order that tests could be repeated by others \nand would be usable in the workplace.
