Exercise decreases autophagy flux in humans.
“In a pilot intervention study, PBMC autophagy flux decreased following 12 weeks of mild exercise in parallel with improved physical function”

Autophagy flux is associated with physical function in humans.
“in adults aged > 70 years, higher autophagy flux was associated with reduced physical function.”

2Loss of ULK1 and ULK2 drives muscle growth in mice but impairs force
While lifelong depletion reduced muscle strength, short-term deficiency in adult mice induced hypertrophy without degrading muscle quality or contractile performance.

Autophagy flux varies by sex and cell type during human aging
In older adults, higher autophagy flux in blood cells linked to lower physical function and decreased after a 12-week exercise intervention.
