Abstract: Rapamycin is known to extend lifespan. We conducted a randomized placebo-controlled study of enteric rapamycin-treatment to evaluate its effect on physical function in old low capacity runner (LCR) rats, a rat model selected from diverse genetic background for low intrinsic aerobic exercise capacity without genomic manipulation and characterized by increased complex disease risks and aging phenotypes. The study was performed in 12 male and 16 female LCR rats aged 16-22 months at baseline. The treatment group w… Show more

“…Longitudinal studies indicate that grip strength decreases throughout aging in mice (Fischer et al, 2015;Zhang et al, 2015;Martinez de Toda et al, 2018;Sheth et al, 2018), rats (Xue et al, 2016;Febo et al, 2020) and humans (Zammit et al, 2019). In humans, grip strength measured late in life is predictive of cognitive decline (Praetorius Bjork et al, 2016;Stijntjes et al, 2017;McGrath et al, 2019).…”

“…The positive effects of activating energetic signaling on muscle function seem somewhat underappreciated. For example rapamycin treatment, which inhibits mTOR, attenuates the age-related losses of strength, lean body mass, and endurance capacity in mice (Fischer et al 2015; Xue and Leng 2016). In addition, three months of rapamycin treatment directly mitigates dynapenia as measured by improved grip strength and rotarod performance in already aged mice (Bitto et al 2016).…”
