a Schematic of experimental design, including both young (3-month-old) and adult (6.5-month-old) groups. b Body mass before and after 20 days of tamoxifen treatment (40 mg kg−1 day−1) in 3-month-old (left, young) and 6.5-month-old (right, adult) control (n = 13 young and 10 adult), AKT-TG (n = 9 young and 11 adult), TSCmKO (n = 11 young and 8 adult) and TSC-AKT (n = 9 young and 5 adult) mice. c Muscle mass after 20 days tamoxifen treatment in young (upper) and adult (lower) mice. d Peak tetanic in vitro muscle force, normalized to 3-month-old control (sex specific), e specific force and f mean twitch profile for both fast-type EDL (upper) and slow-type SOL (lower) muscle. For e, f, n = 21, 17, 17 and 14 (EDL) and 16–17, 14, 14, and 11 (SOL) for control (Con), AKT-TG, TSCmKO, and TSC-AKT, respectively. Data are presented as mean ± SEM. Two-way ANOVAs with Sidak post hoc tests were used to compare data. For e, separate repeated measures two-way ANOVAs were used to compare between control and AKT-TG groups and between TSCmKO and TSC-AKT groups. *, **, and *** denote a significant difference between groups of P < 0.05, P < 0.01, and P < 0.001, respectively. For trends, where 0.05  <  P  <  0.10, p values are reported.
