“Performing eccentric movements – the "lowering" aspect of lifting a weight – pays huge dividends in muscle size and strength, a new study has found. Study participants who lowered weights achieved similar benefits to those who lifted and lowered weights, even though they performed half as many repetitions.”

“These findings suggest that lean muscle mass protects against Alzheimer's disease. However, the researchers noted that whether increasing lean muscle mass can reverse the pathology of Alzheimer's disease in people with preclinical disease or mild cognitive impairment is unclear.”

“Skeletal muscle mass could directly influence survival and could protect against loss of functional status due to aging or the onset of chronic disease. However, since this is an observational nature study, a causal relationship cannot be determined.”

“In addition, participants that were treated with resveratrol had an 8% increase in knee extensor muscle peak torque, 14% increase in average peak torque, and 14% increase in power after training, whereas exercise did not increase these parameters in the placebo-treated older subjects.”

“These findings suggest that creatine supplementation prevents acquired functional disability in older adults. A possible contributor to acquired functional disability is catabolic crisis, a phenomenon defined by periods of accelerated declines in muscle mass and functional capacity.”

“It is possible that the D2 inhibits or competes for an enzyme that is required to produce D3. The mechanism is not known but what is clear is that taking large doses of D2 does lower D3 levels and this leads to more muscle damage post intense workout.”

“From the article: > Lee and his colleagues tested 880 bioactive substances – including drugs and vitamins – approved by the U.S. Food and Drug Administration (FDA) to see if they stimulated the mouse stem cells to become heart muscle cells. The cells were genetically altered to give off a fluorescent bright green color when viewed under a microscrope if they had become heart muscle cells.”

“The investigators measured the participants' muscle strength, body composition, and serum myokine concentration before and after the exercise training intervention. They also grew prostate cancer cells in vitro, exposed them to serum from participants taken before and after exercise training, and observed the effects on cancer cells directly.”

“Those signals may also help enable training-related muscle gene programs and shift fuel use patterns. Training adaptations may therefore depend in part on this learned brain response, not on muscle and cardiovascular changes alone.”

“A consequence of mitochondrial dysfunction is the loss of muscle mass and strength. Findings from a recent study suggest that urolithin A, a compound derived from walnuts and pomegranates, promotes mitophagy, increases muscle strength, and improves performance.”
