Objective: 

An elevated secretion of various adipokines and cytokines, including chemerin, interleukin 6 (IL-6), leptin, retinol binding protein-4 (RBP-4) and tumor necrosis factor alpha (TNF-a) and decreased secretion of adiponectin are considered to play an important role in the development of diseases like the metabolic syndrome and type 2 diabetes. In the present study, the effects of a 12 weeks exercise intervention on serum levels of adipokines and cytokines in obese pre-diabetic men were investigated.

Methods: 

Prediabetic obese men (n = 144) aged 40–65 years were studied at baseline and at 12 weeks in a randomized controlled multi-centre intervention study. Their BMI varied from 25.1 to 34.9. The subjects were randomised to one of three groups: (1) a control group (C, n = 47) that had no supervised exercise during the intervention period, (2) a Nordic walking group (NW, n = 48) that trained aerobically 60 minutes with Nordic walking exercises three times per week, or (3) a resistance training group (RT, n = 49) that trained 60 minutes with strength and power type exercises three times per week.

Results: 

Both types of exercise decreased significantly serum chemerin concentrations compared to control group. In addition, plasma leptin concentration decreased in the NW group. There were no significant changes in the circulating concentrations of adiponectin, IL-6, RPB-4 and TNF-a and in energy intake during the intervention period between study groups.

Conclusions: 

Nordic walking decreased circulating leptin concentrations after 12 weeks of intervention in prediabetic obese middle-aged men and both types of exercise had regulatory effects on circulating chemerin.
