Abstract OBJECTIVE: Muscular fitness levels have been associated with cardiometabolic risk in children, although whether body weight acts as a confounder or as an intermediate variable in this relationship remains controversial. The aim of this study was to examine whether the association between muscular fitness and cardiometabolic risk factors is mediated by body mass index (BMI). DESIGN AND METHODS: Cross-sectional study using a sample of 1158 schoolchildren aged 8-11 years from the province of Cuenca, Spain. We measured anthropometrics and biochemical variables and we calculated a...

Abstract We aimed to examine (a) the construct validity and reliability of the International Fitness Scale (IFIS) in children; and (b) the association of both self-reported and measured fitness with cardiometabolic risk. Cross-sectional study in 1145 Spanish children (9-12 years). We measured body fat, waist circumference, blood pressure, lipids, insulin, and fitness level (reported and measured). A validated cardiometabolic syndrome index was used. An age- and sex-matched sample of 245 children originally not included in the study sample fulfilled IFIS twice for reliability purposes....

Objective: To conduct a meta-analysis of randomised controlled trials aimed at testing whether school-based physical activity programmes improve cardiorespiratory fitness (CRF) in children. Design: Systematic review with meta-analysis. Data sources: Using keywords, we performed a computerised search in five databases: MEDLINE, EMBASE, CINAHL, Web of Science and SportDiscus. Eligibility criteria for selecting studies: Studies that assessed the effectiveness of school-based physical activity programmes on improving CRF in children (3–12 years old). We selected interventions that included an...

Abstract Background Studies that have examined the impact of a physical activity intervention on cardiometabolic risk factors have yielded conflicting results. The objective of this study was to assess the impact of a standardized physical activity program on adiposity and cardiometabolic risk factors in schoolchildren. Methods Cluster randomized trial study of 712 schoolchildren, 8–10 years, from 20 public schools in the Province of Cuenca, Spain. The intervention (MOVI-2) consisted of play-based and non-competitive activities. MOVI-2 was conducted during two 90-minute sessions on...
