Prof. Troy Hornberger from the University of Wisconsin–Madison delivered a lecture titled “Visualizing the Sites of Mechanically Induced Growth in Skeletal Muscle.” His research focuses on how mechanical load activates mTORC1 signaling and where this growth-regulating machinery operates within muscle fibers. Using advanced imaging and molecular approaches, his work identifies the subcellular sites where hypertrophy begins, providing new insights into the biology of exercise and neuromuscular health. A key point discussed was the difference between pulse activation and chronic activation: while transient, pulse-like stimulation promotes muscle growth, chronic activation has a detrimental effect on longevity.
