Comparison of in vitro force production characteristics and fatigue resistance. Force frequency curves were generated from FDB (n = 6), EDL (n = 5), and soleus muscles (n = 4). A Absolute force (mN). B Specific force (N/cm2) corrected to CSA. C Specific force (N/cm2) corrected to PCSA. D Percent decline in baseline force during a 10-min fatigue resistance protocol. E Time (s) to maximum force. F Half-relaxation time (s). Time to maximum force and half-relaxation times for each muscle were averaged from 100 Hz contractions. F–H Comparison of passive stress lengthening contractions between the FDB and EDL (mN/mm2) corrected to CSA and PCSA, respectively. *, FDB v.s. EDL p < 0.05; †, FDB v.s. soleus p < 0.05; #, EDL v.s. soleus p < 0.05. Data are mean ± SEM
