Contractile effects of α/β CaMKII co-overexpression. A) Mean + SE of values for the contractile parameters time-to-peak-twitch force (TTP), half-relaxation time (HRT), maximum twitch force (Ftwitch) and maximum tetanic force (Fmax) for the SOL and GM muscle combined being subjected to control-transfection (light grey filled bar) or α/β CaMKII-transfection (dark grey filled bar). Values reflect values relative to the average seen in non-transfected muscle (n = 7). *, p ≤0.05 vs. control-transfected muscle. Repeated ANOVA with post hoc test of Fisher (n = 11). B) Scatter plot of mean + SE of force values of fifty paced tetanic contractions in non-transfected, control-transfected, and α/β CaMKII-transfected GM muscle. n = 6-9 per group.
