Abstract
Background: The evaluation of exercise effects on the prevention of various diseases is one of the major research fields. In this research, the effect of swimming training on the prevention of kidney crystal deposit and damages induced by ethylene glycol was investigated.
Materials and Methods: In this experimental study, 24 rats were randomly divided into four groups: Control (C), treated with: ethylene glycol 1%(EG), swimming training (SW) and (EG+SW) group that concurrently received ethylene glycol 1%+ swimming practice. Rats in EG and EG+SW groups received 4 weeks drinking water containing1% ethylene glycol. The rats in SW and EG+SW groups were performed swimming training over 6 weeks, three sessions a week for 45 minutes. At the end of the swimming session, rats were euthanized, and kidneys, ureters and bladder tissue samples were histologically evaluated after haematoxylin & eosin staining.
Results: Crystal deposition were observed in all urinary system epithelium surfaces together with renal damages in EG-treated rats, but not observed in urinary system tissue samples of C and SW groups. Renal crystals were detected in renal tissues of EG+SW group was lower than EG group. The total stones were detected in the renal tissue, ureters and bladder and its size in the EG+SW group were significantly lower than EG group (P=0.003). Renal tissue damages of EG+SW group due to ethylene glycol were much less pronounced than EG group.
Conclusion: The swimming training can prevent from renal stones formation induced by ethylene glycol and reduce the tissue damage caused by it.

Abstract
Background: β3-AR and ERK2 are key factors in regulating adipose tissue metabolism and its conversion to brown adipose tissue. Therefore, the present study aimed to investigate the effect of a period of swimming training with different temperatures on the expression of β3-AR and ERK2 genes in the visceral adipose tissue of diabetic rats.
Materials and Methods: 28 male 2-month-old Wistar rats with a mean weight of 200±20 g were selected. After diabetic induction through streptozotocin solution, divided into 4 groups: 1) healthy control, 2) diabetic control, 3) diabetic water swimming training 5 °C and 4) diabetic water swimming training 36 °C (n=7 per each group) were divided. The training groups trained aerobic swimming training for 5 days/week for 4 weeks according to Protocol. One-way ANOVA and Tukey Post-hoc tests were used to analyze the data.
Results: A significant decrease in β3-AR gene expression was observed (P=0.0001), and the results showed that this difference was significant between pairs of healthy control groups compared to other groups (P=0.0001). Also, ERK2 gene expression showed a significant increase (P=0.0001), and the results showed that this is a significant difference between pairs of healthy control groups with water swimming training 36 °C (P=0.001) and diabetic control group with water swimming training 36 °C (P=0.001).
Conclusion: Four weeks of swimming training decreased β3-AR and increased ERK2, which can be concluded to play an important role in the metabolism of white adipose tissue and its conversion to brown adipose tissue.
