“…However, this paper did not analyze socioeconomic variables, which may also be aids in individual's level of physical activity (Pate, Mitchell, Byun, & Dowda, 2011;Sallis et al, 2000). Thus, interventions that aim to increase the level of physical activity can help reduce sedentary lifestyle and excess weight in adolescents (Dutra, Kaufmann, Pretto, & Albernaz, 2015;Silva, 2013).…”

In the last two or three decades, physical activity (PA) has gained increasing recognition as being essential for maintaining good health and improving quality of life for all ages. To evaluate the nutritional status, oxidant/antioxidant, and inflammatory markers, in sports adolescents, a cross sectional study has done in west Algeria. A total of 110 athletes adolescents from special sport classes, aged 11-17 years, were compared to a non athletes group (n=60). Blood pressure, anthropometric and serum parameters were measured. Daily energy intake (DEI) was estimated using 24 hours recall, followed by a 3-days record. Energy expenditure (EE) was evaluated by the International Physical Activity Questionnaire-short form (IPAQ-S). Oxidant/antioxidant and inflammatory markers were determined. An increase in body weight and height (p<0.001) was noted in athletes compared to non athletes. DEI was similar in both groups, whereas EE was higher in athletes than non athletes (p<0.001). Serum triacylglycerol (TG) values were lower in athletes group than in non athletes (p<0.05). Enhanced values were observed in glutathione peroxidase (GPx) (p<0.001), and superoxide dismutase (SOD) (p<0.05) activity, and tumor necrosis factor-α (TNF-α) (p<0.01) in athletes compared to non athletes. Significant relationships were found between height, weight, albumin, GPx, TNF-α, IL-1, and EE. Significant associations were noted between GPx (OR=0.14; 95% CI 0.03, 1.05), inflammatory markers TNF-α (OR=0.47; 95% CI 0.28, 0.80), IL-1 (OR=1.17; 95% CI 0.28, 0.80) and physical activity. Significant relationships were found between weight (P < 0.001), height (P < 0.01), albumin, GPx, IL-1, TNFα (P < 0.05) and EE. In spite of inadequate DEI in athletes adolescents, beneficial effect of sport is observed by lowering serum TG concentrations. However, more research in this area is warranted to clarify sport nutrition needs to provide better and healthy nutritional guidance to young athletes.

“…This behavior has to be underlined as the multisensor method has been demonstrated to be population-specific [17] showing reduced estimation error of EE in overweight children and adolescents. Noticeably, this population spent most of their daily life in sedentary activities (i.e., watching television, working/gaming at the computer/consol) [7,8,20]. LeBlanc and co-workers observed that children averaged about 8.5 h of daily sedentary activities [21], while data from epidemiological studies demonstrated that school age children spent only about 9 % of daily time in moderate physical activities [22,23].…”

Energy expenditure in obese children: evaluation of a new multisensor device

et al. 2015

Purpose Overweight and obesity are increasing among Italian children, particularly due to sedentary lifestyle. The evaluation of daily energy expenditure (EE) is therefore relevant to assess the level of physical activity in subjects at risk. Portable devices could improve the free-living EE monitoring, provided they are properly calibrated and validated. The present study aimed at evaluating a new multisensor wrist monitor (WM) (E3 Ò , Empatica srl, Italy) in EE assessment in obese children and adolescents. Methods Twenty-eight participants (15 males; age 13 ± 2 years; mean ± SD) were enrolled. Nineteen subjects were obese (body mass index (BMI) [95th percentile for age and sex). Subjects were tested (1) while sitting (SIT), and during (2) walking at comfortable speed (SS) and (3) at faster speed (FS). EE was assessed in each condition by both indirect calorimetry (IC, by oxygen consumption measurement) and multisensor (accelerometry, heart rate, skin galvanic reaction, temperature) methods. Results EE measured during SIT, SS and FS was 1.48 ± 0.31, 4.25 ± 0.68 and 5.64 ± 0.92 METs with IC and 1.19 ± 0.11, 3.82 ± 0.77 and 5.17 ± 0.81 METs with WM, respectively. A significant difference (P \ 0.01) between measurement methods in SS and FS condition (pooled data) disappeared in obese individual subgroup. The linear regression coefficient between EEs obtained by the two methods was 0.79 (P \ 0.05), and the BlandAltman plot showed a proportional bias. Conclusions EE estimated by the multisensor wrist monitor highly correlated with the values obtained by IC, particularly in the subgroup of obese children and adolescents, suggesting that it can be used to monitor physical activity in this specific population.
