Irregular force-frequency relationship in MG29-deficient skeletal muscle. Isometric tension at several frequencies was determined in EDL muscles from 8–9-wk-old mice. Typical recording from wild-type and mutant muscles are shown in A. Bars, 1 g/mg wet weight. Force-frequency relationships in MG29-deficient and wild-type muscles are shown in B. Each value normalized to the maximum force represents the mean ± SD. (n = 8–9 from five mice). Significant differences between the groups were observed by t test (asterisk indicates P < 0.05; two asterisks indicate P < 0.01).
