Introduction. The published data showed the importance of metabolic control in preventing complications in metabolic syndrome (MS) and the role of nutritional medical therapy in glycemic control and in the control of dyslipidemia, hypertension, weight loss/normalization (in overweight or malnourished subjects). Objectives. This study follows the evolution of sarcopenic index (SI) and other clinical parameters (body mass index (BMI), homeostasis evaluation index (HOMA index)) correlated with MS after diet therapy or diet therapy combined with sports, in patients with MS. Patients and methods. Our research was conducted during 12 months, on 110 patients >18 years of age, with HOMA index>2, divided into three groups: control group (CG, N=20), diet therapy group (DTG, N=58), diet therapy and sports group (DTSG, N=32). HOMA index for insulin resistance was calculated as the product of resting plasma insulin (in microunits/milliliter) and plasma glucose (in millimoles/liter), divided by 22.5. SI was determined using BIA, as being the ratio between muscle mass and fat mass, measured in cm2 /m2 . Results. A significant decrease of BMI (p<0.05) in DTG (from 31.63 to 24.50) and DTSG (from 30.18 to 24.17) vs. CG was observed (Pearson coefficient r=0.281, p<0.001). Weight status changed significantly (p<0.05) in the high-risk patients. There was a significant decrease of HOMA index (p<0.05) in DTG (from 5.93 to 2.57), DTSG (from 3.93 to 2.23), and in CG an increase was observed (from 3.15 to 3.37). Conclusion. The best results in the prevention/ treatment of sarcopenia in MS patients were obtained for DTSG, which benefited from both the positive effect of diet and physical activity.
