Objective: To evaluate a relationship between the effect of Specific Health Guidance and change in skeletal muscle volume, we examined the skeletal muscle index (SMI) at the time of the Specific Health Guidance and at the follow-up evaluation for examinees who had metabolic syndrome.
Methods: Forty-five persons with metabolic syndrome were enrolled in this study. The Specific Health Guidance mainly concerned diet, walking and smoking. The bio-electric impedance method was used to determine the SMI.
Results: There was no difference in the mean SMI of the 45 subjects between the initial guidance and follow-up evaluation. The changes in SMI were -1.84 ± 2.46% in a reduced SMI group (RG: n=16), -0.38 ± 2.14% in a partially reduced group (PRG: n=22), and 0.76 ± 1.29% in a not-reduced group (NRG: n=7). There was a significant difference in change in SMI between the RG and NRG (p < 0.05). There were positive relationships between percentage change in SMI and change in body weight, percentage change in body weight, and abdominal circumference, respectively (p < 0.05; p < 0.05; p < 0.05).
Conclusion: In order to maintain skeletal muscle mass, it may be necessary to add resistance training and protein supplementation to regular Specific Health Guidance.
