Brain gains: study tests if 'Fractal' pacing supercharges strength training

This study investigates whether adding natural variability (fractal-like patterns) to metronome-paced strength training leads to faster and better brain adaptations compared to standard pacing. Sixty healthy adults aged 18-40 will perform leg extension exercises three times a week for four weeks, with their brain and muscle responses measured using transcranial magnetic stimulation and other tests. The goal is to understand how movement variability might improve rehabilitation for injuries or age-related muscle decline.
