AMPK
A protein kinase that senses cellular energy status and is activated when the AMP/ATP ratio rises. It is an upstream regulator of the mitochondrial biogenesis pathway.
Timeline (last 90 days)
Endurance exercise promotes mitochondrial proliferation and functional improvement by activating the AMPK-PGC-1α pathway, enhancing muscle oxidative capacity and improving metabolic health.
PGC-1α is called the master regulator of mitochondrial biogenesis; AMPK senses cellular energy status (it is activated when the AMP/ATP ratio rises).
Compounds that directly activate AMPK (such as metformin and AICAR) can partially mimic the metabolic effects of exercise, but may interfere with the adaptive response to exercise itself and lack muscle selectivity.
