Muscle Memory: Truth or Myth?


Motor Memory
• Movements learned and stored in brain
• Practice and feedback help revise motor plan
for later retrieval
Muscle Memory
• Substantial muscle mass lost due to disuse
• Regains mass in shorter period time than
initially developed
• Nuclei retained even if proteins gone - new
proteins synthesized at accelerated rate with
exercise/nutrients
