“…The inverse relationship between objectively assessed PA and body fat agree with previous studies. [1][2][3][4][5][6][7][8][9][10][11] Lohman et al 6 reported a significant association of total body fat assessed by anthropometry with MVPA and vigorous PA. Wittmeier et al 3 investigated 251 Canadian children aged 8-11 years and observed that time spent in MVPA was inversely correlated with body mass index and a skinfold-derived Abbreviations: MVPA, moderate and vigorous physical activity; PA, physical activity. All variables were log transformed, except light and moderate PA.…”

“…All variables were log transformed, except light and moderate PA. Physical activity and body composition D Moliner-Urdiales et al estimate of body fat, whereas Ruiz et al 5 reported that only vigorous PA was associated with the sum of five skinfold thickness. Studies using more sophisticated techniques to assess body composition showed more consistent results.…”

“…There is compelling evidence that objectively assessed physical activity (PA) is negatively associated with markers of total [1][2][3][4][5][6][7][8][9][10] and central body fat, 8,[11][12][13][14] in children and adolescents, 15 but with contradictory results. 16,17 Most of the epidemiological studies used anthropometry to assess body composition because it is the most feasible method when large samples need to be assessed.…”

Objectives: To examine the association of objectively assessed physical activity (PA) with markers of total and central body fat in adolescents, and to determine whether meeting the current PA recommendations (X60 min day À1 of at least moderate intensity PA) is associated with reduced levels of total and central body fat. Subjects/Methods: A total of 365 Spanish adolescents aged 12.5-17.5 years participated in this cross-sectional study. PA was assessed by accelerometry and expressed as average PA (counts per minute), and min day À1 of light, moderate, moderate to vigorous (MVPA) and vigorous PA. MVPA was dichotomized into o60 min day À1 and X60. Total body fat was measured by DXA, BodPod and the sum of six skinfolds. Central body fat was measured by DXA at three regions (R1, R2 and R3), and waist circumference. Results: All markers of central body fat were negatively associated with vigorous PA (Po0.01) after controlling for sex, age and pubertal status. Abdominal adiposity measured at R1, R2 and R3 was also negatively associated with MVPA (Pp0.001), and with average PA (Po0.01). All markers of total body fat were negatively associated with vigorous PA (Po0.01), MVPA (Po0.01) and average PA (Po0.05). Adolescents engaged on at least 60 min day À1 MVPA presented lower levels of total (Po0.05) and central body fat (Pp0.01). Conclusions:The results suggest that vigorous PA may have a greater effect on preventing obesity in adolescents than does PA of lower intensity, whereas both average PA and at least moderate PA may have an impact on total and central body fat in youth.

“…It has been shown that variation in CVF was significantly explained by at least moderate -vigorous (3-6 METs) physical activity in children and adolescents. 10,11 Moreover, improvements in CVF can be obtained through regular participation in moderate and vigorous levels of physical activity. 39,40 Collectively, this may indicate that physical activity could have a positive impact on low-grade inflammation through the improvement of CVF.…”

“…Less is known about the association of low-grade inflammation with cardiovascular fitness (CVF) in prepubertal children. Because of the strong correlation seen between CVF and fatness in young people, [8][9][10][11] it is possible that deleterious consequences ascribed to adiposity may be partially due to the influence of low CVF. If so, it would imply that interventions to prevent states of low-grade inflammation should focus not only in weight reduction, but also on enhancing CVF.…”

Objective: To examine the associations of low-grade inflammation with objectively measured physical activity, cardiovascular fitness (CVF) and fatness in prepubertal children. Design: Cross-sectional study. Subjects: One hundred and forty-two children (74 boys and 68 girls) aged 9-10 years (pubertal stage I and II) from the Swedish part of the European Youth Heart Study. Measurements: Total physical activity and its intensity levels (moderate, vigorous, moderate þ vigorous) were measured by accelerometry. CVF was measured with a maximal ergometer bike test. Body fat was derived from the sum of five skinfold thicknesses. The measured low-grade inflammatory markers include C-reactive protein, fibrinogen, complement factors C3 and C4. Results: C-reactive protein and C3 were negatively associated with CVF (b ¼ À0.254 and À0.267, respectively, Po0.05) and positively associated with body fat (b ¼ 0.439 and 0.446, respectively, Po0.001), after controlling for sex, age and pubertal development. C-reactive protein and C3 were not significantly associated with CVF once body fat was in the model. Low-grade inflammation was not associated with physical activity, but physical activity was associated with CVF. Conclusions:The results showed that low-grade inflammatory markers were negatively associated with CVF and positively associated with body fat in prepubertal children. For most of the variables, the influence of fatness was slightly higher than the influence of CVF. The findings suggest that the potential beneficial effects of physical activity on low-grade inflammation may be explained by its association with CVF. Understanding the interplay between physical activity, CVF and fatness may be of importance to reducing cardiovascular disease risk in young people.

Abstract: The results suggest that PA of vigorous intensity may have a greater effect on preventing obesity in children than does PA of lower intensity, whereas both total and at least moderate to vigorous PA may improve children's CVF.
