Brief Summary:
Purpose: Kefir (alcoholic fermented dairy product made by fermenting cow's milk, goat's milk, or sheep's milk) to determine the effect of 12 weeks of human consumption of whey postbiotics derived from lactic acid bacteria in improving muscle strength and intestinal microbiome in elderly people compared with placebo intake.
* Primary objective: To evaluate the effectiveness of whey postbiotics derived from kefir lactic acid bacteria compared to placebo intake through the results of the grip strength test for both hands.
* Secondary objective: To evaluate the effectiveness and safety of whey postbiotics derived from kefir lactobacilli for muscle strength improvement as assessed by dual energy x-ray absorptiometry (DXA), adipokines, myokines, and cytokines compared with placebo intake. The investigators aim to analyze the differences in the intestinal microbiome compared to placebo intake through fecal collection and NGS (Next Generation Sequencing).
Experimental product: Kefir lactic acid bacteria-derived whey postbiotics (oral intake of 6g per day (3g twice per day))
Control product: Flavor 2.7%, Calcium carbonate 13.8%, Lactose 41.3%, Maltodextrin 10.3%, Sugar 31.23%, Carboxy methyl cellulose 0.67% (oral intake of 6g per day (3g twice per day))
Number of subjects: In this human application test, in order to calculate the number of study subjects, the investigators referred to previous studies and calculated the lean mass gain (kg) of 3.3 ± 1.5 kg (mean ± SD) after consuming whey postbiotics derived from kefir lactic acid bacteria for 12 weeks. In the placebo group, it was assumed to be 1.8 ± 1.6 kg.
The statistical hypothesis test of the evaluation variable is a two-sided test.
The significance level is 5%. ③ The test power is maintained at 90% and the type 2 error is set at 0.2. ④ The ratio between the test group and the control group is divided at 1:1.
The calculation of the number of subjects referred to existing research, and a T-test was performed using the G power program to use the mean of the statistical difference in muscle strength improvement between the two groups divided according to the intake of whey postbiotics derived from kefir lactic acid bacteria as the mean (test power) (1-β)=0.9, significance level (α)=0.05, effect size (ES)=0.97 (Cohen's d)). The total number of research subjects required for human application testing calculated through this is 48. Here, the investigators plan to recruit a total of 60 research subjects, assuming a dropout rate of 20%.
