 Mitochondrial dysfunction is a common feature in many diseases, including type 2 diabetes, cardiovascular disease, metabolic syndrome, cancer, and Alzheimer's disease. Recently, there has been a surge of research into the causes and consequences of mitochondrial dysfunction, leading to a greater understanding of its role in disease development. Physical activity is also believed to play a role in mitochondrial function, as it is encoded in our genes and is essential for proper cellular metabolism.
