The invention discloses an application of a ferroptosis inhibitor in preparation of a preparation for improving the motion function of aged individuals. Through transcriptome sequencing analysis, Tfr1 expression in skeletal muscle and muscle satellite cells is reduced along with age increase. The specific knockout of the Tfr1 muscle satellite cells leads to irreversible inactivation of the muscle satellite cells.
