Detailed Description
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.

Outcome Measures
Primary Outcome Measures
- muscle mass [From Baseline, 6 weeks and 12 Weeks Assessed]
Use dual-energy X-ray absorptiometry, DXA (Lunar iDXA, GE Healthcare, IL, USA) for no-entry measurement to determine muscle mass
- 30 seconds chair stand test [From Baseline, 6 weeks and 12 Weeks Assessed]
30 seconds chair stand test will be used as a self-test. Number of stands will be counted.
- Grip strength [From Baseline, 6 weeks and 12 Weeks Assessed]
Use the armed grip machine to measure, hold each of the left and right hands three times until they are weak, and record the maximum value
Secondary Outcome Measures
- Generalized Anxiety Disorder 7-Item, GAD-7 [From Baseline, 6 weeks and 12 Weeks Assessed]
The GAD-7 Anxiety Questionnaire involves 7 items assessing how often participants have felt bothered by anxiety-related problems over the past two weeks. Each item is rated on a Likert scale from 0 (not at all) to 3 (nearly every day). The total score is the sum of responses and ranges from 0-21; where 0-4 = minimal anxiety; 5-9 = mild anxiety; 10-14 = moderate anxiety; 15-21 = severe anxiety
- Geriatric Depression Scale, GDS [From Baseline, 6 weeks and 12 Weeks Assessed]
It consists of 30 questions questioning the mood in the last week. This short form consists of 15 questions questioning the mood of the patient. The answers are given according to the feelings in the last week; The answers are "yes" or "no" and 1 point is given for "yes" or "no" answers depending on the question. For the long form: Normal 0 - 10, Mild 11 - 20, Moderate to Severe 21 - 30.For the short form: Normal 0 - 4, Mild 5 - 9, Moderate to Severe 10 - 15.
- Q-LES-Q [From Baseline, 6 weeks and 12 Weeks Assessed]
Participants who receive app-CBT will have greater improvement on quality of life, assessed using The Quality of Life, Enjoyment, and Satisfaction Questionnaire - Short Form (Q-LES-Q). The Q-LES-Q-SF is a self-report measure of subjective quality of life, containing Likert items ranging from 1 (Very Poor) to 5 (Very Good). Total scores are presented as a percentage of the maximum value (i.e., ranging from 0 to 100, with higher scores indicating greater quality of life).
- Visual Analogue Scale for GI symptoms, VAS-GI [From Baseline, 6 weeks and 12 Weeks Assessed]
Visual Analogue Scale for GI symptoms, VAS-GI (visual analogue scale, VAS 0-10) was designed to measure the response of symptoms and well-being in patients after taking probiotics
- PGI-C [From Baseline to 12 Weeks Assessed]
The PGIC is a scale participants use to rate the level of change they have experienced following treatment. The PGIC is a 7-point scale from 1 (very much better) to 7 (very much worse).
- 10 meter walk [From Baseline, 6 weeks and 12 Weeks Assessed]
Use a pyramid and a measuring tape to measure a distance of ten meters, and ask the subject to stand up from the chair, go around the pyramid and sit down, and record the time
- fat percentage [From Baseline, 6 weeks and 12 Weeks Assessed]
Use dual-energy X-ray absorptiometry, DXA (Lunar iDXA, GE Healthcare, IL, USA) for no-entry measurement to determine fat percentage
