“Global guidelines recommend 150 to 300 minutes of moderate activity, 75 to 150 minutes of vigorous activity, or an equivalent combination each week, plus muscle strengthening. A practical mix can preserve sustainable Zone 2 work while adding vigorous intervals when health, fitness, and recovery allow.”

“These findings highlight the value of adding purposeful moderate and vigorous movement to everyday light activity. Current guidance recommends 150 to 300 minutes of moderate activity or 75 to 150 minutes of vigorous activity each week, plus muscle-strengthening activity.”

“However, the investigators noted a few generalizations regarding the outcomes. The participants' energy expenditure, core body temperature, fasting insulin levels, bone mass, muscle size and strength, and markers of oxidative stress and DNA damage decreased.”

“Before any training-like stimulation, the brain needed a slightly stronger magnetic pulse to activate the hand muscle after the nap. This suggests that the overall strength of communication between brain cells was lower after the nap than after staying awake.”

“When the researchers combined DunedinPACE, muscle mass, and standing balance in one prediction model, it performed almost as well as the larger 12-biomarker model. This suggests that some aging markers may capture overlapping information rather than adding entirely new insight.”

“While BMI is a flawed method for measuring obesity, on a population level, most Americans that experience BMI increases are not doing so because they have been working hard to gain muscle (those individuals are the exception).”

“It is known that exercise (both aerobic and non-aerobic) causes branched chain amino acids to be taken up into muscle cells. This alleviates competition with tryptophan for transport into the brain thus allowing tryptophan to be converted into serotonin.”

“- Matthew Walker, Ph.D. Mechanisms impairing glucose regulation There have been several mechanisms that have been shown to cause glucose dysregulation, including: Changes in muscle and liver glucose absorption.”

“The circadian rhythm is controlled by a central clock in the brain and by peripheral clocks in skeletal muscle, adipose tissue, and other organs. Together, these clocks coordinate the expression of genes related to a variety of metabolic processes with daily light, eating, and activity cycles.”

“Based on findings from more recent stable isotope studies, which more accurately assess muscle protein anabolism and catabolism, evidence suggests that eating 1.2 to 1.6 grams of protein per kilogram of body weight is likely optimal for muscle protein synthesis, especially as one ages.”
