Figure 7From: Effects of high-fat diet and physical activity on pyruvate dehydrogenase kinase-4 in mouse skeletal muscleOxidative capacity estimated by electron microscopy. (A) There were no statistical differences between any of the groups in the area of subsarcolemmal mitochondria relative to the length of the sarcolemma when electron microscopic micrographs were analysed. n = 5 animals/group. Black bars = sedentary, grey bars = running. (B) Electron microscopic image from the subsarcolemmal mitochondria. Scale bar 2 μm.Back to article page
