“Dr. Patrick describes increased shear as a possible way vigorous exercise can damage fragile circulating tumor cells; this is a proposed mechanism, not proof that a workout eliminates metastasis or treats an established tumor.”

“In this excerpt from Dr. Rhonda Patrick’s A4M LongevityFest 2023 keynote, she reviews a randomized trial in sedentary middle-aged adults. Two years of progressive, supervised aerobic training increased VO2 max and reduced left-ventricular stiffness.”

“Wearable-device research in more than 25,000 adults who reported no structured exercise linked about three one- to two-minute vigorous bouts per day with substantially lower all-cause, cardiovascular, and cancer mortality.”

“Controlled human studies support acute brain-related responses to high-intensity exercise. Six short all-out cycling intervals improved selected learning and executive measures while increasing circulating BDNF, IGF-1, and VEGF; lactate tracked several of these changes.”

“When produced during exercise (especially high intensity workouts like cycling, which shifts metabolism toward glycolysis to more quickly meet the high energetic demands), lactate switches on more than 600 genes involved in muscle adaptation, stimulates mitochondrial biogenesis – the process of making new mitochondria – and promotes protein synthesis, which is essential for muscle growth.”

“Dr. Rhonda Patrick talks at SF Nerd Nite about transgenerational effects of caloric restriction on longevity, B-vitamins silencing bad genes, cognitive stimulation reversing neurodegenerative disease, exercise increases neurogenesis, and ways in which vitamin D might influence aging.”

“A systematic review found no overall improvement in mood after cold-water immersion, while a small randomized trial found that repeated whole-body cryotherapy improved depression scores when added to standard pharmacological treatment.”

“In 15 people with severe traumatic brain injury, sodium lactate infusion increased brain lactate, pyruvate, and glucose without raising intracranial pressure, and a randomized study in 60 patients with mild traumatic brain injury reported better cognitive recovery than hypertonic saline.”

“In an early randomized workplace study, healthy employees who completed an eight-week mindfulness program showed a greater rise in antibodies after influenza vaccination than a waitlist group.”

“In eight young men, seven days of 1,000 milligrams of NR per day changed selected muscle NAD metabolites but did not alter substrate use, mitochondrial respiration, or signaling involved in adaptation to one hour of endurance exercise.”
