“Another important way exercise delays muscle atrophy is through the induction of mitochondrial biogenesis which is the growth of new healthy mitochondria. The fact that urolithin A was able to induce biomarkers of both mitophagy and mitochondrial biogenesis is quite compelling.”

“A severe complication associated with spinal cord injury is the loss of respiratory function, which often occurs due to paralysis of the diaphragm muscle. A 2018 study showed that BDNF delivery to the injured spinal cord improved respiratory function in rats.”

“Sarcopenia, the age-related decline in muscle mass and strength, exposes many older people to frailty, falls, and loss of independence. Exercise helps, yet the added value of antioxidant supplements in this setting is uncertain.”

“How sauna use has been shown to enhance athletic endurance in humans, stave off muscle atrophy, and improve the regrowth of muscle after disuse in animals. The potential for brain benefits, including the growth of new brain cells, improvements in focus, learning, and memory, and even potentially ameliorating depression and anxiety.”

“Dr. Rhonda Patrick puts aerobic exercise and resistance training first for improving glucose control. She points to standard weekly activity targets, brief vigorous movement, and muscle gain because contracting muscle takes up glucose.”

“The effect is temporary, but it can help create a useful window of alertness. Dr. Patrick connects both effects with muscle glucose uptake, lactate signaling, blood flow, and brain-derived neurotrophic factor.”

“While traditional saunas can impair performance, infrared saunas may offer a more effective and comfortable recovery option. A recent study found that using infrared saunas after exercise enhances power production but doesn't influence muscle growth.”

“Multiple studies have found that taking NSAIDs such as ibuprofen may reduce muscles’ ability to recover after exercise, blunt adaptations in muscle stem cells, and put excessive stress on the kidneys in people that vigorously exercise. One mechanism by which NSAIDs blunt some of the positive effects in muscle is through the inhibition of inflammatory mediators such as prostaglandins.”

“Conventional training produced clearer improvements in aerobic fitness and blood triglyceride levels. Neither program clearly enhanced insulin sensitivity, reduced liver fat, or meaningfully altered key insulin signaling proteins in skeletal muscle.”
