Figure 2. Tetanic [Ca2+]i and force changes before, during and after fatigue.
Typical [Ca2+]i and force transients recorded from a single soleus fibre injected with indo-1 during stimulation with 1000 tetani at 2 s intervals. The numbers above the traces refer to the number of that tetanus in the series. Note that the [Ca2+]i and force records show little change over the series of tetani.
