Why Your Muscles Grow After the Workout, Not During It
New Science Reveals the Hidden Energy Switch That Controls Muscle Growth

· Resistance exercise activates AMPK, temporarily suppressing muscle protein synthesis
· AMPK shifts role post-workout, triggering a powerful anabolic rebound 1–2 hours later
· Muscle growth is a recovery process — not a result of exertion

“…scientists made a surprising discovery: caffeine doesn’t act on this growth switch directly. Instead, it works by activating another important system called AMPK, a cellular fuel gauge that is evolutionarily conserved in yeast and humans.” #DNA #epigenetics #coffee #ISOGG #geneadons #caffeine #AMPK #MTOR

Caffeine could slow cellular ageing, new research shows how

Queen Mary University of London

Another paper about AMPK. This gives a good overview as well as information about AMPK activation.

Takeaway: If you wish you had access to Metformin but don't, you might want to look into what this paper says about AMPK activation.

AMPK activation—protean potential for boosting healthspan

AMP-activated kinase (AMPK) is activated when the cellular (AMP+ADP)/ATP ratio rises; it therefore serves as a detector of cellular “fuel deficiency.” AMPK activation is suspected to mediate some of the health-protective effects of long-term calorie ...

Researchers discover how #caffeine could slow cellular #aging
Caffeine has long been linked to potential #health benefits, including reduced risk of age-related diseases. But how it works inside our cells, and what its exact connections are with nutrient and stress-responsive #gene and #protein networks, has remained a mystery—until now. Caffeine doesn't act on this growth switch directly. Instead, it works by activating another important system called #AMPK.

Researchers discover how caffeine could slow cellular aging

A new study from the Cellular Aging and Senescence laboratory at Queen Mary University of London's Centre for Molecular Cell Biology reveals how caffeine—the world's most popular neuroactive compound—might do more than just wake you up.
