Table 3 Oxidative capacity estimated by SDH staining

From: Effects of high-fat diet and physical activity on pyruvate dehydrogenase kinase-4 in mouse skeletal muscle

SDH stain intensity Low-fat diet High-fat diet
Sedentary (n=4) Running (n=12) Sedentary (n=8) Running (n=7)
Least oxidative (%) 32.5 ± 18.0 39.4 ± 15.2 49.8 ± 18.4 30.3 ± 26.2
Intermediate (%) 42.8 ± 12.3 35.8 ± 7.3 33.4 ± 11.8 39.0 ± 15.6
Most oxidative (%) 24.7 ± 8.7 24.8 ± 11.1 16.8 ± 7.8 30.7 ± 16.8§
  1. According to the SDH staining of the QF muscle, HFexe mice yielded the highest measure of SDH activity,i.e. the largest area of the most oxidative fiber types (vs.HFsed P < 0.05). § = vs. HFsed (P < 0.05).
