Implication

Prospective controlled study reveals enhanced lumbar spine bone accrual in prepubertal boys receiving daily physical activity, suggesting early skeletal benefits against osteoporosis.

Key Points

To evaluate the skeletal impact of a one-year daily school-based physical exercise intervention on bone mineral content, bone density, and bone size in prepubertal boys.
Non-randomized prospective controlled study of 81 boys aged 7–9 years receiving 40 minutes per school day of exercise versus 57 age-matched controls receiving standard physical education of 60 minutes per week for 1 year.
Dual X-ray absorptiometry (DXA) measured bone mineral content (BMC) and areal bone mineral density (aBMD) of the total body, third lumbar vertebra (L3), and femoral neck, with bone width calculated for L3 and the femoral neck.
The intervention group exhibited significantly greater annual gains than controls in L3 BMC (mean difference of 5.9 percentage points, P < 0.001), L3 aBMD (mean difference of 2.1 percentage points, P = 0.01), and L3 width (mean difference of 2.3 percentage points, P = 0.001).
Across the combined cohort, total exercise duration correlated positively with L3 BMC (r = 0.26, P = 0.003), L3 aBMD (r = 0.18, P = 0.04), and L3 bone width (r = 0.24, P = 0.006).
