Effect of Lactobacillus Paracasei PS23 on Improving Aging and Muscle Loss in the Elderly

Taiwan has become an aging society in recent years. There are important issues to attenuate aging and activate the potential capacity of elderly population. The physical function of middle-aged and older people will degenerate with age and produce age-related diseases. Common symptoms are organ function deterioration, and old age disability caused by malnutrition and muscle loss is also a common care problem. Therefore, how to prevent the complications of muscle loss is one of the important ten years of geriatric research. Although past research has been confirmed, it can improve the debilitating condition of the elderly through nutrition counseling and exercise intervention. However, there is not much in-depth discussion on how probiotics can improve muscle loss and delay symptoms in elderly people. Therefore, this study refers to the supplementation of PS23 in human experiments to help the elderly maintain muscle mass, delay muscle loss, promote physical activity, and delay the occurrence of disability and debilitation in elderly people. One hundred and twenty elderly people will be recruited and then divided into three groups with 40 people in each group: (A) placebo group, (B) PS23 probiotic group, (C) PS23-HT prebiotic group, supplemented for 12 weeks. The diet record, functional test and muscle mass will be carried out every six weeks after the start, to understand whether PS23 is effective in improving muscle loss and weakness in elderly people.
