Table 3. Average strain values (microstrain, µε) for the applied forces used for in vivo tibial compression.

Age (mo)	Force (N)	Gage Site	Max Periosteal: Tension	Max Endocortical: Tension	Min Periosteal: Compression	Min Endocortical: Compression
2	−7.5	1290	1540	1080	−2200	−1340
4	−10	1340	1520	1030	−2320	−1270
7	−8.5	1480	1690	1040	−2490	−1390
12	−11	1510	1720	1050	−2520	−1390

Strains were measured at gage site; values at other sites obtained by linear interpolation of measured value based on cross-sectional geometry; shaded cells indicate target values.
