“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 this clip, Drs. Levine and Patrick discuss genetic and environmental factors that can accelerate or slow epigenetic aging. Dr. Levine also discusses the aging clock she created and how it can be used, along with other biomarkers, to determine an individual's rate of aging.”

“Dr. Patrick explains some of the early evidence that suggests the value prolonged fasting (48+ hours) may have from the standpoint of tissue rejuvenation and healthspan maintenance, as well as relevance for other more specific conditions.”

“A large meta-analysis found that protein supplementation improved resistance-training gains in muscle size and strength, with little additional lean-mass benefit above an estimated total intake of about 1.6 grams per kilogram per day for most participants.”

“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.”

“In a randomized crossover study of 18 young men with overweight or obesity, ten three-minute walking or squat breaks spread across 8.5 hours reduced post-meal glucose exposure more than uninterrupted sitting or one continuous 30-minute walk.”

“In a UK Biobank study of 25,241 adults who reported no leisure-time exercise, about three daily bouts lasting one or two minutes were associated with 38 to 40 percent lower all-cause and cancer mortality and 48 to 49 percent lower cardiovascular mortality compared with no VILPA.”

“A later crossover study using a lower weight-based dose found its clearest benefit in reasoning, while several memory, accuracy, fatigue, and sleepiness outcomes did not reliably improve. Routine muscle supplementation and acute sleep-loss research use different protocols.”
