Original Research Impact of Curriculum-Based Bone Loading and Nutrition Education Program on Bone Accrual in Children

411 – 425

The purpose of this study was to investigate the influence of jumping activities and nutrition education on bone accretion in prepubescents. Fourth-grade children were divided into four groups: jumping (n = 61), nutrition (n = 9), jumping plus nutrition (n = 14), and control (n = 28). Interventions spanned the fourth and fifth grade academic years. Assessments were gathered at 0, 8 and 20 months. Baseline BMD values were (mean ± SD): lumbar (0.752 ± 0.095 g/cm2), neck (0.794 ± 0.089 g/cm2) and total (0.907 ± 0.060 g/cm2). There was a significant increase in BMD over time. However, the interventions produced no significant effects. Twice weekly jumping and/or biweekly nutrition education did not influence bone accrual.
