Figure 5From: Streptozotocin-induced diabetes prolongs twitch duration without affecting the energetics of isolated ventricular trabeculaeTwitch heat as functions of active stress and stress-time integral at 3 Hz stimulation. Representative (A and C) and average (B and D) heat-stress and heat-STI (stress-time integral) relations under isometric contractions at variable muscle lengths for Control (thin lines) and STZ (thick lines) trabeculae. The slope of the average heat-STI relation (in D ) is lower in the STZ group.Back to article page
