Mitochondrial adaptation

Topic

Mitochondrial adaptation refers to the coordinated physiological and structural changes in mitochondria, including alterations in their quantity, quality, and cristae density, in response to physiological stressors such as exercise training, hypoxia, or metabolic demands. These adaptations enhance the cellular capacity for oxidative phosphorylation, energy production, and metabolic efficiency, particularly within skeletal muscle. Key regulatory mechanisms driving these adaptations include mitochondrial biogenesis, fusion, fission, and mitophagy.
