Introduction: The increasing burden of costly chronic disease warrants novel effective interventions. Many conditions stem from childhood. While exercise benefits both bone and fat, the nature of exercise recommendations for each is different. Development of a simple paediatric exercise program for both bone and fat is therefore indicated. The objective was to determine the effect of a novel, brief, enjoyable, feasible, school-based exercise regimen targeting both bone and fat on body composition of primary school children.

Methods: A nine-month, school-based, controlled exercise intervention trial was conducted (Ethical approval #: PES/25/11/HREC). The intervention (EX) comprised 10 minutes of thrice-weekly capoeira and jumping. Anthropometrics, waist circumference (WC), calcaneal BUA and SI, maximum vertical jump (VJ), cardiovascular endurance (predicted VO2 max), resting heart rate (HR), blood pressure (BP) and maturity (YAPHV) were examined. A subset of DXA-derived WB, LS and FN BMD, lean and fat mass, and pQCT-derived indices of tibial and radial geometry and density were also collected. Between-group differences were examined using two-way ANOVA, controlling for YAPHV and initial values. Stepwise regressions were conducted to examine the influence of independent variables on outcomes.

Results: 296 children, including 166 EX (10.5±0.5yo; YAPHV -2.1±0.9yo) and 130 control (CON) (10.7±0.6yo; YAPHV -1.9±0.9y) participated. EX improved WC (EX: 1.95±2.82 cm; CON: 4.09±4.05 cm; p=0.001), HR (EX: -4.11±3.35 BPM; CON: 0.22±3.8 BPM; p=0.001), VJ (EX: 3.47±4.01; CON: -0.59±5.16; p=0.001), predicted VO2 max (EX: 2.68±3.96; CON: -0.20±3.38ml/kg/min; p=0.001), SI (EX: 6.25±10.04%; CON: 4.09±6.99%; p=0.05) and BUA (EX: 3.99±9.06dB/MHz; CON: 1.33±8.3dB/MHz; p=0.01), compared with control. Baseline BUA and maturity predicted 32.2% of the variance in BUA change for boys (p=0.001). BMI and baseline BUA accounted for 16.4% of the variance in BUA change for girls (p=0.006).

Conclusions: School-based capoeira with jumping improved metabolic and musculoskeletal health of primary school children. The exercise program was safe, enjoyable and feasible in the school schedule.
