detraining

The other elements of the division will be sent in to reinforce you from the detraining.

Subsequent detraining leads to atrophy but no loss of myo-nuclei.

Since in vivo imaging have confirmed that cell nuclei are added during strength training and not lost upon subsequent detraining, the nuclei might provide a mechanism for muscle memory.

On subsequent detraining, the fibers maintain an elevated number of nuclei that might provide resistance to atrophy; on retraining, a gain in size can be obtained by a moderate increase in the protein synthesis rate of each of these many nuclei, skipping the step of adding newly formed nuclei.
