In Aging Cell, researchers have described how different combinations of gut bacteria impact muscle strength in mice. Expanding upon a known link The link between gut bacteria and health is well-documented, and multiple biomarkers have confirmed that a healthy gut leads to health elsewhere [1]. This is not just due to inflammation caused by pathogenic...

A recent study linked probiotic-induced gut microbiome and metabolite changes to improved muscle functioning in older sarcopenia patients [1]. Sarcopenia and the gut Sarcopenia is an age-related condition. People with sarcopenia suffer from a reduction in muscle mass, strength, and function, leading to a decreased quality of life and increased morbidity and mortality [2]. The...

In a study published in Aging Cell, researchers have outlined a relationship between mitochondrial fragmentation in skeletal muscle and the loss of strength with age. Broken power plants Why We Age: Mitochondrial DysfunctionAs they age, the mitochondria in our cells lose their ability to provide cellular energy and release reactive oxygen species that harm cells...

In Aging Cell, researchers have described the specific cell types that give exercise protective effects against motor nerve degeneration. A different level of back problems With aging, the prevalence of nerves connecting to muscle tissue dwindles, a phenomenon known as denervation [1]. This has been linked to a depopulation of the alpha motor neurons in...

A recent paper has reported on improving muscle function in aged mice through combined treatment of exercise and the inhibition of NNMT, an enzyme involved in NAD+ metabolism [1]. Age-related muscle loss Muscle loss is a common problem in the aging population. Studies estimate that “after age 50, adults lose approximately 1% of their muscle...

In Aging Cell, researchers have published a paper on a cellular energy source that appears to be a key signaling molecule in sarcopenia. A little-explored molecule Sarcopenia, a condition that increases with aging, reduces muscle mass in older people, and leads to a decreased quality of life [1], has been documented to have multiple root...
