In addition, people who like to exercise, athletes, and the like desire to increase their muscle mass in order to improve their performance. Furthermore, as people become more health-conscious, how to increase muscle mass is becoming a social issue in improving quality of life (QOL), improving frailty, and preventing locomotive syndrome. It has become a challenge. In addition, “frailty” is a weakened state between a healthy state and a state in which life functions are impaired or a state requiring nursing care due to increased vulnerability to stress due to a decrease in physiological reserve in old age. It is a word indicating a state (Non-Patent Document 1).
  • Non-Patent Document 2 Muscle is mainly composed of protein and free amino acids. Also, branched-chain amino acids are known to act as stimuli to promote protein synthesis. Therefore, conventionally, foods and drinks containing various proteins and amino acids have been used to increase muscle mass (Non-Patent Document 2). In recent years, it has also been reported that ingestion of Bifidobacterium bacteria can thicken myotubes and increase muscle mass, and is expected to be a new active ingredient for increasing muscle mass ( Patent document 1).
