Figure 4From: Improvement of diaphragm and limb muscle isotonic contractile performance by K+ channel blockadeEffects of 3,4-diaminopyridine (DAP) on changes in isotonic work of diaphragm, extensor digitorum longus (EDL) and soleus during repetitive 20 Hz stimulation at a load of 40%. P values indicate results of 2-way RMANOVA testing for each panel, and asterisks (*) indicate significant differences at each load per the Newman-Kuels test.Back to article page
