Intact ex vivo muscle force development. Force development of isolated muscles was determined before, following 5-min intermittent fatigue and after 20-min recovery and represented as a percentage of maximal tetanic force at the end of the equilibration period (% of Tmax). A: force of isolated extensor digitorum longus (EDL) muscles was similarly decreased in high capacity runner (HCR; black square) and low capacity runner (LCR; white circle) muscles following fatigue treatment and LCR force remained decreased following recovery compared with HCR. B: force of isolated soleus (SOL) LCR muscle was half that of HCR following fatigue but similar after recovery. *P < 0.05.
