“The loss of muscle mass and strength, known as sarcopenia, is a significant problem in aging, affecting both healthspan and quality of life. Findings from a recent study suggest that vitamin D affects muscle function through diverse metabolic pathways.”

“Protein is essential for maintaining muscle mass as we age. Modulating protein intake via dietary intake or fasting can have variable effects on aging and muscle growth. Whereas fasting turns off multiple pathways associated with aging, such as mTOR, IGF-1, growth hormone, and others, eating for optimal fitness activates these important processes.”

“Dr. Patrick also discusses heat during periods of reduced loading and after resistance training. A controlled human immobilization study found that repeated heat therapy reduced muscle atrophy and helped preserve plantar-flexor strength.”

“There are caveats for older adults, who might benefit from a little supplemental leucine to offset their lower protein intake. In this clip, Dr. Stuart Phillips explains the importance of dietary protein quality and the role of the amino acid leucine in muscle protein synthesis.”

“Contracting skeletal muscle increases glucose uptake by moving GLUT4 transporters toward the cell surface through pathways that are partly independent of insulin. This gives active muscle another way to clear glucose during and after exercise, and the effect can continue for hours after the session.”

“In a controlled mouse study, researchers tested whether a demanding training program could make old skeletal muscle look epigenetically younger. The experiment included young and aged mice.”

“For example, bodyweight exercises including air squats, burpees, and pushups with short rest periods, can provide a middle ground between aerobic conditioning and strength gains. In this clip, Dr. Martin Gibala highlights that functional training offers a time-efficient method to enhance cardiorespiratory fitness and muscle conditioning simultaneously.”

“The good news is that collagen supplementation may have benefits beyond this specific role. Collagens are major structural proteins in many body tissues, including tendons, ligaments, cartilage, skin, blood vessels, muscles, gut tissue, and dentin.”

“Evidence suggests that fasting flips a metabolic “switch,” liberating fat stores via fatty acid oxidation and ketone production. Findings from a recent study suggest that ketones induce a deep resting state in muscle stem cells, protecting them from future stressors.”

“Muscle mass decreases markedly with aging, compromising overall fitness and contributing to frailty, disability, and falls. Findings from a recent study suggest that dietary fiber helps reduce muscle mass losses associated with aging.”
