“Researchers measured participants' glycated hemoglobin levels (HbA1c, a measure of long-term blood glucose control), body composition, and muscle glycogen stores before and after the intervention.”

“The study, including participants between the ages of 51 and 80 years old, showed that those with a low musculoskeletal fitness were 2 to 5-times more likely to die over 6 years than those with better muscle fitness.”

“In this review, researchers present the science surrounding the role exercise plays in skeletal muscle NAD+ metabolism in both young and older people. Learn more about NAD+ in our overview article.”

“A new study suggests that sulforaphane mitigates sarcopenia and cardiac dysfunction via activation of Nrf2. Sarcopenia, the loss of muscle tissue that occurs during the aging process, and cardiac dysfunction are common features of aging.”

“Then they restored cardiotrophin-like cytokine factor 1 levels in older mice and found that muscle strength, glucose tolerance, and mitochondrial activity improved. Bone density also increased as the myokine reduced bone-resorbing cells and boosted bone-forming cells.”

“The good news is that the muscle atrophy, bone loss, and inflammation were reversed if the mice were returned to a normal dark-light cycle (not exposed to light during their rest hours).”

“Moderate intensity exercise releases a lipid-controlling hormone (called lipokine) that causes skeletal muscle to take up fatty acids (in both mice and humans). The release of the lipokine also correlated with an increased capacity for mitochondrial energy production in humans and improved VO2max. It also seems to decrease circulating triglycerides.”

“FTA: > Scientists have shown that a protein they previously demonstrated can make the failing hearts in aging mice appear more like those of young health mice, similarly improves brain and skeletal muscle function in aging mice.”

“Sleep deprivation increases stress hormones, which have been shown to increase the degradation of proteins in skeletal muscle, and reduce secretion of anabolic hormones.”

“DNA damage at telomeres drives senescence in cardiac cells. Removing senescent cardiac muscle cells from the hearts of aged mice, both genetically and using drugs, reduces hypertrophy and fibrosis in aged hearts and restores cardiac health.”
