Abstract
Introduction:
The increasing incidence of both chronic bone and obesity related disease places a heavy burden on health economies. Both conditions may arise in childhood. While exercise in youth is beneficial for both bone and metabolism, the nature of exercise recommendations for each traditionally differs.
Aim:
Our goal was to determine the effect of a brief, novel, enjoyable, school-based exercise regimen targeting both bone and fat in primary school children.
Methods: A controlled exercise intervention trial was conducted over a full
school year (9 months). The intervention comprised 10 minutes of thrice weekly capoeira and jumping activities. Anthropometrics, waist circumference
(WC), calcaneal broadband ultrasound attenuation (BUA) and stiffness index
(SI) (Lunar Achilles, GE), maximum vertical jump (VJ), cardiovascular endurance (predicted VO2 max), resting heart rate (HR), blood pressure (BP) and maturity (YAPHV) were recorded at baseline and 9 months. A subset of whole body (WB), lumbar spine (LS) and femoral neck (FN) BMD, lean and fat mass (DXA, XR800, Norland), and indices of tibial and radial morphology and density (pQCT, XT3000, Stratec) was also collected. Changes in outcome variables were compared between groups using two-way ANOVA, controlling for YAPHV and initial values. Stepwise linear regression were performed to determine the relationships between bone parameters.
Results:
296 children, including 130 control (CON) (10.7 ± 0.6yo; YAPHV -1.9 3.47 ± 4.01; CON: -0.59 ± 5.16; p = 0.001), predicted VO2 max (EX: 2.68 ± 3.96; CON: -0.20 ± 3.38 ml/kg/min; p = 0.001), SI (EX: 6.25 ± 10.04%; CON: 4.09 ± 6.99%; p = 0.05) and BUA (EX: 3.99 ± 9.06 dB/MHz; CON: 1.33 ± 8.3 dB/MHz; p = 0.01) compared to control. Sex-specific effects largely mirrored those findings. Baseline BUA and maturity predicted 32.2% of the variance in BUA change (p = 0.001) for boys; while BMI and baseline BUA accounted for 16.4% of the variance in BUA change (p = 0.006) for girls.
Conclusion:
School-based capoeira with jumping improved markers of metabolic and musculoskeletal health in primary school children. The exercise program was safe, enjoyable and easily incorporated into the school schedule.
