Muscle Loss May Be Slowed With HMB, Leucine and Exercise
Sarcopoenia is the degenerative loss of skeletal muscle mass, muscle quality and muscle strength that occurs with advancing age. While muscle loss is a natural part of aging, there are steps that can be taken to reduce it. Researchers suggest that a combination of resistance exercise, HMB and essential amino acids may help people maintain muscle health.
For their analysis, the researchers examined PubMed and Dialog medical research databases for studies published between January 2000 and October 2013. They measured the prevalence of sarcopenia, as well as the efficacy of physical interventions and nutritional supplementation in improving the symptoms of sarcopenia.
They found that resistance training was effective at improving muscle strength and physical performance. They also found that nutritional supplementation with leucine and HMB may improve muscle parameters.
Based on their findings, the researchers recommend supervised resistance exercise and supplements of essential amino acids with leucine and HMB to help people maintain muscle mass as they get older.
Researchers from the European Union Geriatric Medicine Society conducted this study. It was published on September 21, 2013, in the journal Age and Ageing.
Leucine is an essential amino acid that stimulates skeletal muscle protein synthesis, which starts the muscle building process. It is not, however, the only nutritional supplement that can help build muscle. Previous studies suggest that diary protein and creatine (which is found in red meat and supplemental form) may help as well.
HMB is a metabolite of the amino acid leucine. Recent studies have found that it may reduce the risk of sarcopenia and help support physical strength and functionality.
