exercise-mimetics
Exercise mimetics are compounds designed to replicate the physiological benefits of physical activity without requiring actual exertion, a concept originally developed in animal and human health research. In plant science, this idea has inspired investigations into whether analogous stress-mimicking treatments—such as mechanical stimulation compounds or signaling molecules—can trigger plants' natural resilience pathways, potentially strengthening stress tolerance, growth, or defense responses without requiring the plant to undergo actual physical stress. This approach could offer new strategies for enhancing crop robustness and resource-use efficiency in agricultural settings.

Gut bacteria from exercise-trained mice produce metabolites that protect muscles from wasting, even in mice that never exercised. Oral doses of two of those metabolites reduced muscle loss and preserved muscle function, positioning them as potential stand-ins for physical activity.
Gut content transfers from exercise-trained donor mice reduced hindlimb muscle atrophy in immobilized sedentary recipients compared with sedentary donors
Oral administration of pipecolic acid and succinate attenuated muscle atrophy and preserved muscle function in exercise-naive mice
Untargeted metabolomics confirmed both metabolites were enriched in cecal contents, serum, and muscle tissue consistent with microbial origin rather than host synthesis
