1Sarcomere length denotes the distance from one Z-disk to another Z-disk, μm.
2The potential for hydrogen; lower values are more acidic, higher values are more alkaline.
3μg Ca2+/μg mitochondrial protein.
4Control, saline injection; LPS50, 50 ng LPS/kg BW; LPS100, 100 ng LPS/kg BW.
x,yMeans with the same variable with different superscripts denote differences across aging (P < 0.05).
