New explanation for muscle memory found in muscle proteins
Briefly

Research from the University of Jyväskylä revealed that muscles retain a memory of resistance training through protein modifications that last over two months. Participants engaged in ten weeks of resistance training, then did not train for ten weeks, followed by another training period. Researchers found that muscle proteins showed specific changes during these phases, indicating a biochemical basis for muscle memory. This finding alleviates concerns about muscle loss during short-term breaks, as the muscle retains some benefits from previous training, leading to quicker regain of strength.
The study showed for the first time that muscles 'remember' training at the protein level, suggesting that muscle memory persists for over two months.
This stress over muscle loss is partly unnecessary, as the effects of resistance training persist for two months, enabling quicker gains upon resuming training.
