HyperKPP soleus and EDL but not diaphragm generated less tetanic force than wild-type muscles. (A–C) Tetanic force was elicited with a 200-msec train of 0.3 msec, 10-V square pulses at 140 Hz for the soleus and 200 Hz for the EDL and diaphragm. Data were acquired immediately after adjusting the length for maximum force at the beginning of an experiment. The tetanic forces from every experiment including those for EM measurements were used to calculate mean tetanic force. Error bars represent the SEM of 24 solei, 34 EDL, and 44 diaphragms. *, mean tetanic force of HyperKPP muscles was significantly different from that of wild type; ANOVA and LSD; P < 0.05.
