Basal Muscle Amino Acid Kinetics, Protein Synthesis in Young vs Old
Sarcopenia, the term for loss of muscle mass, is another of those theories that contributes to aging. As we age, we lose muscle mass; muscles are a major player in maintaining insulin sensitivity. Therefore, sarcopenia may be a triggering event for the imbalances in sugar handling that lead to so many other chronic diseases. This study suggests that age-related sarcopenia is not caused by a generalized slow down of muscle cells. There may be some other trigger that the body responds to that initiates the muscle loss. Resistance training in elderly individuals is a powerful tool to combat sarcopenia.
