Changes of cell length and peak shortening (PS) amplitude in cardiomyocytes from control or caloric restricted (CR) WT and Akt2 knockout (KO) mice. A. Resting cell length at various stimulus frequencies (0.1–5.0 Hz); and B: PS at various stimulus frequencies normalized to that obtained at 0.1 Hz from the same cell. Mean ± SEM, n = 26 - 36 cells from 4 mice per group, *p < 0.05 vs. WT group, #p < 0.05 vs. WT-CR group.
