In particular, it is well-established that the stress of exercise provides a powerful stimulus that can trigger transient or enduring changes to mitochondrial molecular features, activities, integrated functions, behaviors, and cell-dependent mitochondrial phenotypes. Evidence documenting the many beneficial mitochondrial adaptations to exercise has led to the notion of exercise as a mitochondrial medicine.

Here, we provide a physiology-focused overview of molecular crowding, highlighting contemporary advances in our understanding of its sensing and control. Long hypothesized as a form of crowding-induced microcompartmentation, phase separation allows cells to detect and respond to intracellular crowding through the action of biomolecular condensates, as indicated by recent studies. Growing evidence indicates that crowding is closely tied to cell size and fluid volume, homeostatic responses to physical compression and desiccation, tissue architecture, circadian rhythm, aging, transepithelial transport, and total body electrolyte and water balance.
