Fig. 1From: The effect of a physiological concentration of caffeine on the endurance of maximally and submaximally stimulated mouse soleus muscleThe effects of 70 μM caffeine treatment and stimulation frequency on soleus muscle power output following continues work loop stimulation. Values are displayed as a percentage of maximal work loop power output [data represented as mean and SE; n = 8 in each case; significant differences (*p < 0.05) in power output at each individual time point between 140 Hz control and 140 Hz caffeine treated]Back to article page
