Abstract
We introduce new models for studying fiber-type-specific myonuclear dynamics in muscle training, detraining, retraining, disuse, and recovery. We show that the various fiber types do not respond identically and that myonuclear number changes during adaptation. We also critically assess an updated version of MyoVision automated image analysis software to quantify whole muscle immunofluorescent microscopical images in a faster and less computer intensive manner. MyoVision remains open source and freely available with more user-controlled features.
