Adult aging is associated with serial sarcomere number in rats (8% difference in plantaris; 21% difference in vastus lateralis between age groups).
“Age-related SSN loss was apparent after middle age for all muscles, with the plantaris showing the smallest (8%) and the VL the greatest (21%) differences between age groups.”
