“A small randomized, placebo-controlled trial shows a compound that targets mitochondria (called mitoQ) improved dilation of participants' arteries by 42% after 6 weeks, which made their blood vessels look 15 to 20 years younger.”

“Mitophagy, the selective degradation of dysfunctional mitochondria, helps ensure that the body’s cells are metabolically efficient. It occurs when mitochondria self-identify as dysfunctional, offering themselves for mitophagy.”

“In fact, exercise enhances mitophagy whether or not it’s performed in the fasted state. Mitophagy HIIT also enhances mitochondrial biogenesis in skeletal muscle in addition to increasing the effectiveness of existing mitochondria.”

“Learn more about sirtuins. Mitochondrial function Mitochondria are classically thought of as the cell's powerhouses because they generate energy in the form of ATP. They are also deeply involved in cellular metabolism and signaling pathways.”

“Mitophagy ultimately serves as a trigger for mitochondrial biogenesis, the process by which new mitochondria are produced. Failures in mitophagy are associated with several chronic diseases, including cardiovascular disease, kidney disease, and Alzheimer's disease.”

“This mitochondrial DNA is inherited from mother to child and originates in the oocyte (i.e., egg cell) prior to fertilization. Because mitochondria must also maintain a functional genome, they are also susceptible to damage from oxidative stress and radiation.”

“Oxidative stress drives many disease processes. In mitochondria, in particular, it promotes the release of mitochondrial DNA into surrounding cytosol where it can trigger cellular responses involved in autoimmunity.”

“Supplementation with nicotinamide riboside, however, reversed mitochondrial damage, increased mitochondrial biogenesis, and reversed muscular atrophy. Similar results were observed in mice with a mitochondrial mutation defect that causes mitochondria to become dysfunctional with age.”

“It also increased the use of intramuscular triglycerides over glycogen in muscle tissue. Exercise while fasted also caused mitochondria to increase gene activity in genes related to fatty acid metabolism making them more efficient as using fat for energy.”

Dr. Rhonda Patrick explains how vigorous exercise challenges mitochondria, glucose disposal, and cardiovascular fitness.
