“…Children data were collected and published by various authors (e.g. Bandini et al 2006, Spadano et al 2003, 2005, Torun, 1989 and are used to calculate daily energy and nutritional requirements. Again, no school related data were available so far and these are provided in this study.…”

Data on metabolic rates (n=81) and clothing insulation (n=96) of school children and adolescents (A, primary school: age 9-10; B, primary school: age 10-11 year; C, junior vocational (technical) education: age 13-16 (lower level); D, same as C but at advanced level; and E, senior vocational (technical) education, advanced level: age 16-18) were collected (Diaferometer, Oxylog, Heart Rate derivation) during theory-, practical-and physical education-lessons. Clothing insulation was calculated from clothing weight, covered body surface area, and the number of clothing layers worn. Clothing insulation was found to be similar to that expected for adults in the same (winter) season, with minimal variation with age or school type (0.9 to 1.0 clo; 1.38 clo where coverall was worn), but more variation within groups (coefficient of variation 6-12%). Metabolic rate values (W.m -2 ) were lower than expected from adult data for similar activities, but are supported by other child data. The results of this study can be used to establish design criteria for school climate control systems or as general data on energy expenditure for children and adolescents. The results emphasise the need for specific child data and shows the limited value of size-corrected adult data for use in children.

“…13,14 Furthermore, over the childhood period, physical activity appears to decline with increasing age. [15][16][17][18][19][20] Also, the type of physical activity changes with growth and development. Free play or other nonsustained activities give way to more structured activities such as team sports, sports clubs, individual lessons (eg, dance, gymnastics, martial arts), and school-based physical education.…”

“…We found that the age-related changes observed over adolescence in a small sample of girls were influenced by how activity was measured: activity energy expenditure (adjusted for fat-free mass) declined over adolescence, but relative energy expenditure, expressed as the physical activity level (PAL, defined as total energy expenditure/resting metabolic rate), increased over the same period. 17 This observation emphasizes the need to consider definitional issues when evaluating studies in this area.…”

Physical activity and sedentary behavior: a review of longitudinal studies of weight and adiposity in youth

AIM:To review the published prospective observational studies of the relationship of physical activity and sedentary behavior with the development of overweight and adiposity, with an emphasis on methodologic issues. METHODS: Sample size, population studied, length of follow-up, assessment of exposure (physical activity, inactivity, or sedentary behavior), assessment of outcome (relative weight, overweight, % body fatness, adiposity), statistical approach, and main findings were extracted, summarized, and key methodological issues highlighted. RESULTS: In total, 17 studies of physical activity and 15 studies of inactivity/sedentary behavior were identified; as these were not mutually exclusive, 20 unique studies were reviewed. Results were mixed, with most studies showing an inverse association of physical activity with weight or fatness outcomes and/or a direct association of inactivity/sedentary behavior with weight or fatness outcomes. The effects identified were generally of small magnitude. Imprecise measurement of activity exposures likely weakens the observed relationships. Most studies used a pre-post design and had limited duration of follow-up (r2 y). Studies with longer and more frequent follow-up did not always use the most advantageous statistical approach. CONCLUSIONS: On balance, the available evidence from prospective observational studies suggests that increased physical activity and decreased sedentary behavior are protective against relative weight and fatness gains over childhood and adolescence. In addition to improved measurement methods, longer and more frequent follow-up as well as truly longitudinal analysis methods would help establish these important prevention and intervention targets, and identify subgroups or development periods where interventions would likely be effective.

Purpose. The aim of the review was to investigate the relationship between physical activity level (PAL) and nutritional status (NS) in adolescents. Methods. Seven electronic databases were searched for research from the years 2005-2015. The studies must have mentioned the relationship between PAL and NS parameters in adolescents. After the review of abstracts and articles, 22 papers meeting the required criteria were further analysed in detail.Results. The studies included 31,045 subjects of both sexes. The results showed that smaller PAL led to an increase of NS parameters and vice versa. Comparing the total PAL, the total time spent in moderately vigorous physical activity, and the total time of vigorous PA (VPA), only VPA was a significant predictor of the responders' percentage of fat mass. Reducing the activity by 10 MET on the weekly level was associated with an increase in bMI in girls for 0.11 kg/m 2 , while an increase of the activity by 1 hour per week resulted in a decline in bMI by 0.13 kg/m 2 . Conclusions. Total PAL has a significant correlation with NS in adolescents. This relationship is inverse, which means that more active adolescents are less overweight than their less active and/or inactive counterparts and vice versa. In addition to PAL, the character or intensity of physical activity has a significant impact on bMI. Physical activity of higher intensity influenced the reduction of body weight and fat mass more than activity of the same duration but of moderate intensity.

Abstract: Conclusions drawn regarding changes with age in physical activity depend on the measure of physical activity assessed.
