- A Adjusted net difference between change in intervention and control troop-level means (adjusted for baseline age, race, weight; baseline and change in height, menarcheal status, Tanner breast stage).
- * Adjusted for energy intake; and above variables, not including height or change in height)
- @ Calculated variable of total weight-bearing physical activity minutes, MET value, and self-reported intensity.
- Adjusted for above variables (in A), not including energy intake, height or change in height.
- $ Calculated variable of ground reaction force value × (Ln (minutes in activity +1)
