Classification
Intervention class: Behavioral/physical-activity intervention (structured resistance/strength training)
Aliases: Strength training, Resistance training
Relationship to mTOR: Also NOT an 'mTOR inhibitor'. Resistance exercise is a classic acute activator of mTORC1 signaling in skeletal muscle, driving the muscle-protein-synthesis response that underlies training adaptation (hypertrophy/strength gains). This acute, muscle-localized activation is mechanistically the OPPOSITE direction from rapamycin's action and must not be conflated with organism-level 'mTOR activity' claims.
Mechanism summary: Mechanical loading during resistance training acutely activates mTORC1 signaling in skeletal muscle, promoting the protein-synthesis response underlying strength/hypertrophy adaptation. See /mtorc1-vs-mtorc2 for the complex-level map.
Regulatory status
Behavioral intervention; not a drug. No regulatory approval framework applies.
MASTERS: concurrent metformin blunted resistance-training-induced muscle mass/strength gains relative to training + placebo. [study record] verification: verified_2026-07-11
Safety notes
Behavioral intervention; general exercise-safety guidance (e.g. medical clearance and appropriate supervision/progression for resistance training) is standard clinical advice not specific to this dataset. No drug label applies.
