“…The EPAL values found in the present analysis are similar to measured values observed in the literature for people living in both rural and urban regions of developing countries (Bogonha et al, 2000;Yamauchi et al, 2001). In general, average PAL values are found to be approximately 1.90 and 1.68 in rural and urban male populations, respectively.…”

“…Internationally recommended PAL values were first established in 1985 and have remained unchanged (Buyckx et al, 1996) primarily due to data obtained using the DLW technique in affluent societies Coward, 1998) which can be questioned for developing countries, as occupational, degree of urbanisation, technological and behavioural characteristics of these populations are different (Yamauchi et al, 2001) and changing fast. Since the RPAL values are based on theoretical factorial calculations assuming duration and energy costs of daily activities, differences in social mobility and labour patterns between developed and underdeveloped societies and changes in these patterns in the latter may interfere in ER estimation.…”

Objective: To describe a method to estimate physical activity level (PAL) values based on household surveys in which representative information of the population on the distribution of sex, age, occupation and daily working hours is obtained, and to compare them to the recommended PAL (RPAL) values. Design and subjects: Data of 267446 individuals of a probabilistic sample from a Brazilian food consumption and family budget survey were used to estimate two different sets of estimated PAL (EPAL) values: (1) considering sex, age group and geographical area and (2) the above plus expenditure class, defined by the quartiles of per capita expenditure. Results: The EPAL values derived by the proposed method indicated that: (l) the RPAL values for 18+y-old women represent higher energy requirements (ERs) than necessary, which could make these women become obese; (2) the RPAL values for 18 to 59-y-old males can only be used to calculate the mean for the total population, because their use for the rural and urban populations separately will lead to severe physiological effectsFunder-and overnutrition, respectively; and (3) the RPAL values for 10 to 17 and 60+y-old males and 11 to 17-y-old females will lead to undernutrition by not incorporating provisions for the occupational activities. Conclusions: Sex-and age-specific RPAL values are not appropriate for the calculation of ERs of the Brazilian population. PAL values must be estimated and constantly recalculated as soon as the required information becomes available. It is important that these EPAL values be disseminated so that more adequate ERs are calculated.

“…These include studies of tropical agricultural populations from Gambia (Heini et al, 1991(Heini et al, , 1996, Thailand (Muryama and Otsuhka, 1999), Papua New Guinea (Yamauchi et al, 2001), highland Bolivia (Kashiwazaki, 1999), highland and coastal regions of Ecuador (Leonard et al, 1995), and herding and fishing populations from Siberia (Katzmarzyk et al, 1994;Leonard et al, 2002). In addition to the rural, subsistence-level populations, studies have also been done on urban groups from Papua New Guinea (Yamauchi et al, 2001), Bangladesh (Rashid and Ulijaszek, 1999), Colombia (Spurr et al, 1996;Dufour et al, 2002), and Siberia (Leonard et al, 1997(Leonard et al, , 2002. The range of daily EE in these samples is 9.7-16.1 MJ/day (2,300-3,850 kcal/day) in men and 7.0-11.0 MJ/day (1,700-2,600 kcal/day) in women.…”

The measurement of daily energy expenditure is an important aspect of research on human health and nutrition. Over the last 30 years, G.B. Spurr has been a leader in developing and implementing methods for more effectively assessing energy expenditure and physical activity in traditional and modernizing populations. One of his most notable contributions has been the development of the "Flex Heart Rate" (flex-HR) method. Since its inception in the late 1980s, the flex-HR method has become a standard tool for measuring daily energy expenditure in free-living human populations. This article reviews the initial development and validation of the flex-HR technique, and examines recent refinements of the method and its application to research in biomedicine and human population biology. The review and analyses highlight how the flex-HR technique has improved on earlier methods of assessing energy expenditure and greatly advanced our understanding of variability in human energy requirements.

“…Substantial material on Tari has been published by the Japanese scientists (Umezaki, Yamauchi, and Ohtsuka 1999;Umezaki et al 2000;Yamauchi, Umezaki, and Ohtsuka 2001), and the cluster final report describes Miko in some detail. Discussion in this chapter concentrates only on Ogotana and Tumam, where work continued until the end of the project.…”
