Abstract
Purpose:
The CAPO Kids trial was a school-based bone- and fat-targeted exercise intervention that improved bone, fat and physical performance in healthy pre- and peri-pubertal children (1,2). The aim of the current work was to determine if benefits of the CAPO Kids trial were maintained after twelve months of detraining.
Methods:
The intervention involved block randomization of 9-11 year old children into either 8 months of 10 minutes thrice-weekly capoeira plus jumping exercise in addition to regular PE classes (EX), or regular PE classes alone (CON). Testing originally occurred at baseline (T1) and 8 months at the end of the intervention (T2) (previously reported; 1,2). Additional testing was conducted 1 year after withdrawal of the exercise program (T3). Measures included age of peak height velocity, weight, standing and sitting height, calcaneal broadband ultrasound attenuation (BUA) and stiffness index (SI) (Achilles, GE), waist circumference, resting heart rate, blood pressure, maximal vertical jump, and estimated maximal oxygen consumption. Between-group differences at each time point were determined by repeated measures ANCOVA, adjusting for change in anthropometrics, physical activity and calcium consumption.
Results:
240 of the 311 children in the original CAPO Kids trial (77% of initial follow-up sample) were remeasured at T3 (12.3±0.6 yrs); 155 EX and 85 CON. EX and CON increased BUA (EX: 5.6%, p≤0.001; CON: 6.5% p≤0.001; CON: -5.6%, p≤0.001) between T2 and T3 time points, with no between-group differences, reflecting normal growth and maintenance of exercise effects.
Conclusion:
The benefits of an 8-month in-school bone- and fat-targeted exercise intervention to the bone, fat and physical performance of pre-and peri-pubertal children endured even after 12 months of detraining. Findings suggest even brief exposure to targeted exercise during the vital growing years can evoke benefits for metabolic and skeletal health in the longer term.
