The effect of different term swimming exercise in rats on serum leptin levels

Abstract

The aim of this study was to investigate the effect of serum leptin in rats performing various duration swimming exercises. In the study, 30 healthy albino wistar male rats with an average weight of 180-220 grams were divided into 5 groups including; control, water exercises, 15, 30 and 60 minutes swimming groups. Animals were swim-exercised for 90 days. At the end of 90 days, after performed urethane anesthesia, blood samples were taken by intracardiac way. Collected blood was analysed according to procedures. Data were analyzed by using SPSS 15. One-way anova and tukey multiple comparison test were performed in the study. The homogeneity of the variances was examined by Levene's statistic. Results showed that the leptin levels were as follows: control (1480,00 pg/ml), water exercise (705,83 pg/ml), 15 (602,33 pg/ml), 30 (396,67 pg/ml) and 60 (435,83 pg/ml). Statistically significant difference was found between control and 30 minutes swimming group (p=0,012) and control and 60 minutes swimming group (p=0,017) (p<0,05). It is determined that 3 months of different terms (15, 30, 60 minute) of swimming exercise reduces the levels of leptin.
