DHA improves skeletal muscle function under the condition of HFD. A Weight of gastrocnemius (GAS), tibialis anterior (TA), extensor digitorum longus (EDL), and soleus (SOL) from mice in three groups (n = 4 or 5). B Diameter distribution of muscle fibers in TA from mice in three groups (μm) (n > 500). C Inverted screen test of mice in three groups (n = 8). D Running distance test of mice in three groups (n = 8). E Relative mRNA expression of oxidative and glycolytic muscle fiber type markers measured by qPCR in GAS from mice in three groups (n = 6). F Relative mitochondrial content of mice in three groups (n = 6). G Metachromatic ATPase staining of GAS to detect type I muscle fibers (black). Statistical analysis was performed using two-tailed paired Student’s t tests
