“A recent meta-analysis also found small benefits in selected cognitive domains, including memory and processing speed, with responses that may depend on age, diet, baseline stores, stress, dose, and the cognitive test used.”

“A separate six-week randomized study in 30 healthy young adults found that neither 10 nor 20 grams per day improved the tested cognitive outcomes compared with placebo. The result is an important counterweight to the acute sleep-deprivation experiment.”

“Acute stress may create a different context. In a double-blind crossover study of 15 adults undergoing 21 hours of sleep deprivation, a single 0.35-gram-per-kilogram dose changed brain high-energy phosphate measures and improved selected cognitive outcomes.”

“Aging in tumor tissue is markedly accelerated, however – an indicator of the perturbed metabolic and growth processes observed in cancer. In this clip, Dr. Steve Horvath discusses correlations between epigenetic aging and age-related chronic diseases.”

“Sprint-interval exercise improved reaction time on selected executive-function tasks for about 10 to 30 minutes in a controlled study, supporting Dr. Patrick's practice of using a short workout before an early talk or demanding meeting.”

“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.”

“Timing matters when cold exposure follows resistance training. In a 12-week study of 21 men, ten minutes of cold-water immersion immediately after each session attenuated gains in strength and muscle mass and reduced selected anabolic signals.”

“Addressing the widespread issue of physical inactivity requires exploring strategies to encourage more people to engage in various forms of physical activity, including brief and intermittent activities.”

“An emerging strategy in the prevention and (possibly) treatment of neurodegenerative diseases is starving cells as a means to induce general autophagy to help rid the cell of protein aggregates.”

“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.”
