Two aspects: Exercise Powerful Mitochondrial Health. First: Type: Aerobic, Weights, High Intensity, or High Intensity Interval Training. Personally encourage HIIT. Second: An optimum HIIT…personally aim close 30 minutes. Early to avoid later distractions! Excellent commentary Dr. Mercola much reduced time per episode HIIT but repeated say three times a day with sufficient interval. But practical limitations! Need flexible schedules!
Exercise powerful Mitochondrial Health…Time equals muscle wastage.. “whether it occurs in the context of advancing age or debilitating chronic or acute diseases,”…per Nathan K. LeBrasseur, Ph.D. researcher molecular aspects of endurance and exercise, Mayo Clinic.
After 50, strength loss 1.5 % to 5 % yearly. Exercise will minimize this. BUT interestingly among older persons…almost 400 genes working differently after HIIT contrasted to 274 for younger HIIT exerciser… with 274 genes; and only 170 for moderate combination exercisers. This compared to 33 for weight lifters and 19 for moderate exercisers. Genes seem influence through expression mitochondria energy production for muscle cells. Survey involved cyclists, points to explanation our 105 recent record holder! This is fantastic news for Seniors!! It’s literally a gift!
Aside impacting skeletal muscle, exercise induces mitochondrial changes seem benefit liver, brain and kidneys. HIIT provides Nitric Oxide…NO. Impacts underlying waiting molecules in skin, fat, and…separate from natural sunlight…includes resulting mitochondrial electron transport chains, passing electrons derived reduced form eaten foods to combine with oxygen from breathing with water resulting. Process drives protons across the mitochondrial membrane…recharges ATP (adenosine triphosphate) from ADP (adenosine diphosphate). ATP is carrier energy throughout body. Age Mitochondrial decline closely linked reduced cardiorespiratory fitness. Decreased ‘resting’ mitochondrial ATP production may result: insulin resistance development with aging. Exercise promotes mitochondrial health…forces mitochondria work harder…side effects mitochondria making reactive oxygen species, or free radicals, which act as signaling molecules including production more mitochondria. also exercise induces mitochondrial biogenesis in the brain, potential benefits such as reduction or reversal of age-associated declines in cognitive function, and helping to repair brain damage following a stroke. Exercise stimulates AMPK and SIRT1, which secondarily inhibit mTOR that is involved in aging and cancer. This in turn stimulates mitochondrial biogenesis and mitophagy, both of which key component of cancer prevention. Mitochondrial dysfunction core many diseases. Key: force mitochondria to work result Reactive Oxygen Species…free radicals signaling molecules resulting more mitochondria! Exercise Significant Passport Mitochondrial Health
