Bioindicators Associated With Sarcopenia Before and After Intensive Lifestyle Intervention
Study Details
Study Description
Brief Summary
The goal of this clinical trial is to explore whether the bioindicators of body composition, nutrition-related indicators (lymphocytes, albumin), lipids, and thyroid hormones are associated with sarcopenia and the changes in these indicators after an intensive lifestyle intervention. The main questions it aims to answer are:
-
whether the bioindicators such as lymphocytes, albumin, lipids, thyroid hormones, fat mass, fat-free mass, and basal metabolic mass are associated with the development of sarcopenia.
-
the changes of these bioindicators that occur in older adults after going through an intensive intervention.
Participants will receive a 3-month intensive intervention consisting of an intensive nutritional intervention and an individually designed exercise intervention. Nutritional and exercise prescriptions are co-designed through a nutritionist and rehabilitation physician.
Researchers will compare bioindicators in the sarcopenia group before and after intensive lifestyle intervention to determine the association with sarcopenia.

| Experimental: Sarcopenia group After completing screening, 30 subjects in the sarcopenia group received a 3-month intensive intervention consisting of an intensive nutritional intervention and an individually designed exercise intervention. Nutritional and exercise prescriptions were co-designed through a nutritionist and rehabilitation physician. |
Combination Product: 3-month intensive intervention
Intensive nutritional interventions were as follows: i）Estimation of ideal body weight according to height, calculation of calories by giving 30-40kcal/kg/day according to BMI stratification, and calculation of daily protein requirement at 1.5g/kg/day, which was finally converted into daily dietary recommendations according to the results of the calculations. ii）Distribution of additional protein supplementation by whey protein, each sachet containing 15g of whey protein.
The resistance training program included 5 min of warm-up, 20 min of muscle strength training, and 5 min of slow walking and was performed three times a week. Resistance training involved a dumbbell and sandbags as weights for the major muscles of the upper and lower limbs. In the study, aerobic training is brisk walking or jogging for 30 minutes/day, five times a week.

Outcome Measures
Primary Outcome Measures
- AMMI(appendicular muscle mass index) [baseline and 3 month]
Bioelectrical impedance analysis was used to obtain appendicular muscle mass (AMM) and height. The unit of AMM and height were represented as kilogram and meter respectively. AMMI were calculated as AMM/height^2 (kg/m^2).
Secondary Outcome Measures
- Fat mass [baseline and 3 month]
Bioelectrical impedance analysis was used to obtain fat mass. The unit of fat mass was represented as kilogram.
- Fat-free mass [baseline and 3 month]
Bioelectrical impedance analysis was used to obtain fat-free mass. The unit of fat-free mass was represented as kilogram.
- Basal metabolic mass [baseline and 3 month]
Bioelectrical impedance analysis was used to obtain basal metabolic mass. The unit of basal metabolic mass was represented as kilocalorie.
- Lymphocyte count [baseline and 3 month]
Lymphocyte counts were detected using a fully automated hematology analyzer (Mindray BC-6800, Shenzhen, China). The unit of lymphocyte count was represented as 10^9/L.
- Albumin [baseline and 3 month]
Albumin was detected using a fully automated biochemistry analyzer (Hitachi 7600, Hitachi, Ltd., Tokyo, Japan). The unit of albumin was represented as g/L.
- Five items of blood lipid (triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), very low-density lipoprotein cholesterol (VLDL-C)) [baseline and 3 month]
Five items of blood lipid were detected using a fully automated biochemistry analyzer (Hitachi 7600, Hitachi, Ltd., Tokyo, Japan). The units of the five items of blood lipid were all represented as mmol/L.
- Thyroid hormones (thyroid stimulating hormone (TSH), free thyroxine (FT4), and free triiodothyronine (FT3)) [baseline and 3 month]
Thyroid hormones were measured by chemiluminescence immunoassay (Abbott I2000, Abbott, Chicago, USA). The units of FT4 and FT3 were represented as pmol/L. The unit of TSH was represented as μIU/mL.
