“A 2025 network meta-analysis of 217 randomized trials and 15,684 people with knee osteoarthritis found that aerobic exercise was likely the most beneficial exercise category for pain, function, gait, and quality of life.”

“In later randomized trials, urolithin A improved some laboratory measures of muscle endurance or hamstring strength, but it did not significantly improve key primary outcomes such as six-minute walk distance, muscle ATP production, or peak power.”

“Large treadmill cohorts associate higher measured fitness with lower mortality, while a 46-year study of middle-aged men linked the highest fitness category with about 4.9 additional estimated life-years compared with the lowest category.”

“Across the modeled dose-response curves, one vigorous minute corresponded to 4.1 moderate minutes for all-cause mortality, 7.8 for cardiovascular mortality, 5.4 for major cardiovascular events, 9.4 for incident type 2 diabetes, and 3.5 for cancer mortality.”

“Dr. Rhonda Patrick discusses how conditioning the body to heat stress through sauna use, called "hyperthermic conditioning" may cause adaptations that increase athletic endurance (by increasing plasma volume and blood flow to heart and muscles) and potentially even muscle mass. She also discusses the profound effects of hyperthermic conditioning on the brain including cognitive function.”

“Insulin-like growth factor 1 (IGF-1) plays a role during childhood for growth and continues later in life to have anabolic and neurotrophic effects. IGF-1 is also implicated in contributing to aging and enhancing the growth of cancer after it has been initiated.”

Many of the anabolic effects of growth hormone are thought to be mediated by insulin-like growth factor-1, or IGF-1 (https://www.ncbi.nlm.nih.gov/pubmed/18500379), which is synthesized primarily in the liver but also in skeletal muscle in response to growth hormone.

“Study. 01:43:00 - High animal protein intake was only positively associated with cardiovascular mortality among individuals with at least one unhealthy lifestyle risk factor, such as obesity or sedentary lifestyle. Study.”

“01:52:55 - Environmental enrichment creates epigenetic changes that benefit learning and memory in rodents and these benefits transfer to offspring. Study. 02:05:00 - NASA study showed that gravity influenced expression of genes involved in metastasis.”

“Some of the factors contributing to these variable phenotypes include persistent damage to our DNA and mitochondrial dysfunction, driven by an altered NAD:NADH ratio, the latter of which has recently been shown to be improved by certain dietary supplements like nicotinamide riboside.”
