Muscle fiber type-dependence effect of exercise on genomic networks in aged mice models

the intervention period was 4 weeks, and treadmill exercises were conducted for all exercise groups. Two sessions per day were administered. A minimum of a one-hour break was allocated between sessions. the 9-week-old C57BL/6 young male mice and 84-week-old mice were purchased from Central Lab. The groups were divided into young control (YC), young exercise (YE), old control (OC), and old exercise (OE) groups. Each group comprised three mice and all mice were subjected to RNA sequencing analysis. Overall design: Examination of gene expression profiles of young control (YC), young exercise (YE), old control (OC), old exercise (OE) in each soleus and gastrocnemius.
