Physical activity levels in a sample of Oxford school children aged 10-13 years

Article Abstract:

A study of 38 children aged 10-13 from Oxford, UK, indicates that physical educations lessons in school play an important role in the physical activity levels (PALs) of the sample group and that levels are very variable. The girls in the sample showed an average PAL of 1.53, versus the 1.48 recommended by the Department of Health, and the boys 1.50, versus the 1.56 recommended by the Department of Health. The PAL was higher on schooldays. One girl had a level of just 1.20 at weekends.

Report of the working group on energy requirements of infants, children and adolescents

Article Abstract:

Research studies on the energy requirements of infants, children and adolescents are evaluated. Estimates of the energy requirements of these group of individuals should be taken from measurements of energy expenditure and growth. There is a need for database expansion on energy expenditure among well-nourished infants in terms of size and geographic distribution. The doubly-labelled water method offers the most accurate measurement of energy expenditures.
