Abstract

Aim: The aim of this study was to investigate the effect of 12 weeks of aerobic exercise combined with a ketogenic diet on Secreted frizzled-related protein 5 (SFRP5) levels and metabolic syndrome factors in middle-aged men with metabolic syndrome. Methods: 40 middle-aged men with metabolic syndrome were randomly divided into control (n = 10), aerobic exercise (n = 10), ketogenic diet (n = 10), and aerobic exercise and ketogenic diet (n = 10) groups. The intervention groups performed aerobic exercise and ketogenic diet control for 12 weeks. In the pre-test stages and after 12 weeks, SFRP5 protein levels and metabolic syndrome factors (fasting glucose, lipid profile, blood pressure and waist circumference) were evaluated in four study groups. Results: In between-group comparison, the group of aerobic exercise combined with ketogenic diet caused a significant increase in SFRP5 (p=0.04) in middle-aged men with metabolic syndrome compared to the control group. The comparison of other groups in this index did not show any significant difference from each other (p≤0.05). In within-group comparison, the results showed that in all three intervention groups, the level of SFRP5 (aerobic exercise group: p=0.001; ketogenic diet group: p=0.001; and aerobic exercise group with ketogenic diet p=0.001) had a significant increase and the highest increase was in the aerobic exercise group with ketogenic diet. Conclusions: Aerobic exercise combined with a ketogenic diet has better effects than a single aerobic exercise and ketogenic diet to control metabolic risks in middle-aged men with metabolic syndrome.
