“…In addition, we found a lower odd of having excess weight in participants who reported higher intensity of PA during PE classes, and both PE classes and school recesses. Our results are in line with a recent study by Burns et al [39], which showed that lower zBMI was significantly linked to a higher percentage of steps (e.g., higher PA level) accrued during both PE classes and school recesses. Similarly, Fenech et al [40] found that engaging in more than 50% of PE classes in MVPA was associated with reductions in zBMI among Maltese children.…”

Background: Examining the association between excess weight or physical fitness and intensity of physical activity (PA) during Physical Education (PE) classes or school recesses and in children could be of great interest and importance, especially for future intervention programs or public policies related to PA. The aim of this study was to explore the association between intensity of PA in PE classes or school recesses and excess weight or global physical fitness in a sample of Spanish schoolchildren. Methods: We performed a cross-sectional study in the Valle de Ricote (Region of Murcia, Spain). A final sample of 350 Spanish schoolchildren between 6 and 13 years of age was included from six different schools. Intensity of PA during PE classes and recesses was assessed by the Physical Activity Questionnaire for Older Children (PAQ-C). To assess physical fitness, the extended ALPHA fitness test battery was used. Body mass index (z-score) was calculated following the age- and sex-specific thresholds of the World Health Organization. Results: Both body mass index (z-score) and Global Fitness Score (z-score) were lower in schoolchildren engaging in high intensity of PA in both PE lessons and school (p < 0.05 for all). Lower odds of having excess weight were found in those who reported high intensity of PA in both PE classes and school recesses (OR = 0.54; CI 95%, 0.30–0.96). In these same participants, higher odds of being in the high Global Fitness Score tertile were found (OR = 1.96; CI 95%, 1.01–3.85). Conclusions: Our study showed that higher intensity of PA in PE classes and school recesses was associated with lower excess weight and higher global physical fitness.

Objective This study aims to elucidate the dose‒response relationship between 24-h activity behaviors and body fat percentage (BFP) in Chinese preschool children using a compositional isotemporal substitution model (ISM). Methods In a cross-sectional design, 881 children aged 3–6 from urban and rural areas of Jiangxi Province were sampled. Activity behaviors, including sedentary behavior (SB), low-intensity physical activity (LPA), and moderate- to high-intensity physical activity (MVPA), were measured using accelerometers. Sleep patterns were assessed through questionnaires, and BFP was determined by bioelectrical impedance analysis (BIA). The study employed compositional data analysis (CoDA) and ISM to estimate the impact of reallocating durations of different activity behaviors on BFP. Results Higher BFP was found in urban vs. rural children, decreasing with age. Overweight and obesity rates were 10.6% and 7.6%, respectively, above national averages. MVPA and LPA were negatively correlated with BFP, while SB was positively correlated. A 30-min MVPA reduction significantly increased zBFR, particularly in overweight children. Gender-specific nuances revealed that boys' MVPA negatively influenced zBFP (β = -0.155), P < 0.05), while girls' SB positively impacted zBFP (β = 0.636, P < 0.01). Isotemporal simulations emphasized amplified effects in overweight children, with boys' zBFR rising rapidly when MVPA was substituted and girls displaying a notable substitution effect between SB and LPA. Conclusion BFP is closely linked to 24-h activity behaviors, notably in overweight and obese preschoolers. ISM identified MVPA as a critical influencer, with a 30-min reduction substantially increasing BFP. Gender disparities were evident, implicating MVPA in boys and LPA and SB in girls.
