Effects of resistance training on serum adipocytokine levels in rats

Abstract

The effects of resistance training (RT) on serum adipocytokine levels were investigated in rats. Male rats were allocated either to a RT group or a control (C) group. The RT group performed RT by climbing 1-m high cages for access to water. The epididymal, retroperitoneal, and inguinal fat pad weights of the RT were significantly lesser than those of the C group. A significantly lower serum insulin concentration was observed in the RT group than in the C group; no significant group difference was observed in the plasma glucose concentration. The serum leptin level was significantly lower in the RT group than in the C group. On the other hand, no significant difference existed in the TNF-α, adiponectin, and resistin levels between the two groups. The results indicate that the RT improved the whole-body insulin sensitivity and induced differential effects on the serum adipocytokine levels in rats.
