“Patients assigned to supervised exercise during neoadjuvant chemoradiation, followed by continued activity before surgery, were more likely to achieve a complete or near-complete pathological response than those receiving usual care.”

“Dr. Patrick also describes a proposed anti-metastatic mechanism: faster blood flow during vigorous exercise increases shear forces on circulating tumor cells, the cells that have left a primary tumor and entered the bloodstream.”

“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.”

“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.”

“In the modern-day with no imposed fasting, these cycles of renewal may remain dormant. In this clip, Dr. Valter Longo discusses how cellular repair mechanisms may have evolved during times of fasting, but are latent in times of food abundance.”

“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.”

“This is a proposed metabolic advantage, not proof of slower brain aging. Small TBI trials found that sodium lactate lowered intracranial pressure more than mannitol in severe TBI and improved cognitive scores more than 3% sodium chloride in mild TBI.”

“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.”
