The effect of 8 weeks of continuous and high intensity interval swimming on chemerin levels in liver and visceral fat tissues and insulin resistance in male rats with metabolic syndrome

The aim of the present study was to investigated the effect of 8 weeks of continuous and high intensity intermval swimming on chemerin levels in liver and visceral fat tissues and insulin resistance in rats with metabolic syndrome.

After induction of mice, to the metabolic syndrome, for the program performance, Rats (n = 32) randomly were divided into four groups (n = 8) including: standard or normal control, metabolic syndrome control, continuous swimming and high intensive interval swimming (with metabolic syndrome) groups. The continuous and high intensive interval swimmimg trained up to 65% and almost equivalent 100% of maximal oxygen uptake respectively. Blood and tissue (liver and visceral fat) variables were measured by ELISA method and the results were extracted using variance analysis test with repeated measurement.

Continuous and high intensity interval swimming significantly reduced serum glucose level (P = 0.001), but the two types of performed exercises did not significantly changes in insulin resistance (P = 0.77) and liver tissue chemerin (P = 0.228); only high intensity interval swimming significantly reduced visceral adipose tissue (P = 0.0001) and rat weight (P = 0.029).

According to the results of the present study, both continuous and high intensive interval swimming exercises, can be considered as a preventive approach to improve insulin resistance and metabolic syndrome; but performing high intensive interval exercise will be more effective. More researches needed for difinite conclusion.
