TA Tendon Morphological Properties From Adult, Old, and Old RAPA-Fed UM-HET3 Female Mice

	Adult (n = 6)	Old (n = 9)	RAPA (n = 16)
Length, mm	6.5±0.2	6.6±0.2	6.7±0.2
CSA, mm2
Distal	0.087±0.008	0.082±0.010	0.082±0.012
Central	0.136±0.014*	0.132±0.013*	0.133±0.012*
Proximal	0.118±0.011*	0.112±0.009*	0.116±0.016*
Overall	0.113±0.007	0.108±0.007	0.110±0.013

Notes: Values are means ± SD.

CSA = cross-sectional area; RAPA = Rapamycin; TA = tibialis anterior.

*Significantly different from distal region within an experimental group. No effects of age or RAPA treatment were seen for regional CSA.
