Resistance training-like electrical stimulation selectively activates the PKB-TSC2-mTOR signaling cascade, leading to prolonged activation of translational regulators and increased muscle protein synthesis, resulting in hypertrophy.

To build muscle mass, focus on high-intensity resistance training. This activates specific cellular pathways (mTOR) that drive protein synthesis and muscle growth.

GoodSupportsHIGH confidence
HFS selectively activates the PKB-TSC2-mTOR cascade causing a prolonged activation of translational regulators, which is consistent with increased protein synthesis and muscle growth.
