“…This equation also considers the shoe correction (SC), which corresponds to the thickness of the sole of the shoe, that is added to the popliteal height (PH), and can vary according to the culture, fashion and country (many authors report variations in the order of 20 mm, 25 mme45 mm) (Castellucci et al, 2015;Pheasant, 2003). This variable is especially important since the anthropometric measures are collected without the use of footwear (Castellucci et al, 2010b;Gonçalves, 2012;Gouvali and Boudolos, 2006;Parcells et al, 1999;Pheasant, 2003;Prado-Leon et al, 2001). For the purpose of this study, and because it is aimed at children, the shoe correction (SC) of 20 mm was Fig.…”

a b s t r a c tIn a primary education classroom of any country, children of the same age have very different statures, reaching variations of 200 mm (Gonçalves, 2012). However, the school furniture provided is not suitable or adaptable to these differences. Designing school furniture able to respond to these variations is, therefore, a challenge for ergonomics and design in a global market. It is clearly not viable for industries to adapt productions for each country. When competitiveness and limitation of resources are essential for the viability of any product it becomes essential to find a universal system adapted to the requisites of any country.Taking as prescription measure the popliteal height obtained from the data of different countries, a universal measurement system for the school chair and desk set is proposed, combining the ellipse methodology used by Molenbroek et al. (2003) and the (mis)match equations mentioned by Castellucci et al. (2014b).From the results obtained, it can be concluded that only 5 sizes are needed to implement this new measurement system of evolutionary school furniture for the primary education classroom.

Students spend a large portion of their time in school. In this broadened time of sitting, poor fitting furniture can cause various types of musculoskeletal disorders and discomforts. Thus, it is crucial to use anthropometric data to coordinate the arrangement of school furniture. To fulfill this perception, a survey has been conducted in 10 primary schools in Khulna, Bangladesh. Anthropometric measurements were accumulated from 300 students of these primary schools. Seven furniture dimensions were measured and fifteen anthropometric measurements were taken and they were compared to identify potential mismatch. A significant degree of mismatch was found between furniture and student anthropometric measurements. The results highlighted that desktop height and seat height were found too high and seat width was too small for all of the students. The paper also proposes furniture dimensions, which reduce mismatch percentage of students ranging from 90% to 10%.

“…The results show that after 30 subjects were measured, difference between the two devices in all measurements were not larger than 1 mm. Finally, Prado-León et al [48] developed two anthropometers, which were designed based on the Martin type anthropometer, and their accuracy was tested prior to the study. However, the study did not present any results or the formula applied.…”

“…TEM is the most commonly used measure of precision [18,91] and is also presented in ISO 7250-2 [92] It is important to highlight that eight of the studies reviewed mentioned reliability [57,10,54,58] or synonymous terms, such as, repeatability [43,44,46] and consistency [48]. Furthermore, only three of the reviewed studies have evaluated repeated measurements using reliability assessment methods ( Table 1).…”

BACKGROUND: Despite offering many benefits, direct manual anthropometric measurement method can be problematic due to their vulnerability to measurement errors. OBJECTIVE:The purpose of this literature review was to determine, whether or not the currently published anthropometric studies of school children, related to ergonomics, mentioned or evaluated the variables precision, reliability and/or accuracy in the direct manual measurement method. METHODS:Two bibliographic databases, and the bibliographic references of all the selected papers were used for finding relevant published papers in the fields considered in this study. RESULTS:Forty-six (46) studies met the criteria previously defined for this literature review. However, only ten (10) studies mentioned at least one of the analyzed variables, and none has evaluated all of them. Only reliability was assessed by three papers. Moreover, in what regards the factors that affect precision, reliability and accuracy, the reviewed papers presented large differences. This was particularly clear in the instruments used for the measurements, which were not consistent throughout the studies. Additionally, it was also clear that there was a lack of information regarding the evaluators' training and procedures for anthropometric data collection, which are assumed to be the most important issues that affect precision, reliability and accuracy. CONCLUSIONS:Based on the results it was possible to conclude that the considered anthropometric studies had not focused their attention to the analysis of precision, reliability and accuracy of the manual measurement methods. Hence, and with the aim of avoiding measurement errors and misleading data, anthropometric studies should put more efforts and care on testing measurement error and defining the procedures used to collect anthropometric data.Keywords: anthropometry, measurements, repeatability. INTRODUCTIONAnthropometry is the branch of the human sciences that deals with body measurements: measurements of size, shape, strength and working capacity [1]. The anthropometric data are essential for applying ergonomic principles for the design and improvement of a wide range of products for different users [2][3][4]. In school environments, anthropometry has become an important discipline, as it can be used to provide relevant students' anthropometric characteristics, which in turn can be used to provide critical information for school furniture design [5,6]. When the correct anthropometric data and sample population are not consider, a mismatch between anthropometric dimensions and school furniture may occur, which could ultimately result in the development of musculoskeletal disorders within the students and other problems related to the learning process [7][8][9]. Additionally, if school furniture is not locally designed, importers should ensure that the appropriate anthropometric data were considered, so that imported school furniture fits the intended use and users [10]. On the other hand, when employed correctly, anthr...
