Motor cortical excitability is differentially modulated by HIIT and strength exercise.
Journal of sports sciences·July 22, 2026·PMID 42483809
Why it mattersUnderstanding how different exercise modalities modulate corticospinal excitability in non-exercised muscles can inform neurorehabilitation strategies, particularly when targeting remote muscle groups. HIIT may offer superior systemic neuromodulatory effects compared to small-muscle strength exercise, which could influence exercise prescription for motor recovery or performance.
