Macro partitioning
Decline in mitophagy and autophagy with age leads to the accumulation of damaged mitochondria and ROS, contributing to sarcopenia, neurodegeneration, and cardiovascular decline.
Exercise is a known inducer of autophagy and mitophagy. Maintaining physical activity, especially aerobic and resistance training, may help counteract the age-related decline in these clearance pathways, protecting muscle and brain health.
ModerateSupportsMEDIUM confidence
Aged-related declination of autophagy (both mitophagy as well as CMA) promotes sarcopenia by protein accumulation interference with normal myofibers functioning... a decrease in mitophagy is observed in aged animals and this contributes to aging phenotype.
Why this rating
Strong animal model evidence; human data is correlational (e.g., heart failure samples).

- Caloric Restriction (CR) extends lifespan and mitigates aging biomarkers primarily by inhibiting mTORC1 signaling, thereby inducing autophagy, rather than solely through antioxidant effects.Good
- Enhancing autophagic activity, particularly through genetic upregulation of autophagy-related genes (e.g., Atg5) or chaperone-mediated autophagy receptors (LAMP2A), extends lifespan and mitigates age-related physiological decline in mammalian models.Moderate
