Purpose: 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.
Methods: 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.
Results: 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).
Conclusion: 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.
