Introduction: In this study, the effect of aerobic training supplemented with hydro-alcoholic extract of Vaccinium Arctostaphylos fruit on oxidative stress and the antioxidant defense system of the heart tissue of rats was investigated.Methods: 24 male Wistar rats were randomly divided into four groups: 1-healthy control, 2-supplementation, 3-training, and 4-supplementation and training. Rats in the supplement groups received 250 mg of fruit Vaccinium Arctostaphylos per kg of body weight in the form of oral gavage. Aerobic training protocol included running on a treadmill at a speed of 5-24 m/min for 10-60 minutes for eight weeks, five days a week, with the principle of overload. The levels of SOD, TAC, GPX, and MDA were measured in heart tissue. Results: The results showed that the level of SOD increased significantly in the training+supplement group compared to the control group (p=0.044). The level of TAC in the supplement group was higher than the training and training+supplement groups (p

Aim: Estrogens binding to estrogen receptors in the cytoplasm, causing an increase in the synthesis of DNA, RNA and others proteins in the target tissue. Endurance exercises may affect the expression of estrogen receptors in overectomized rats. Therefore, the aim of present study was to investigate the effect of six weeks swimming training on expression of estrogen receptors in the uterus and fallopian tubes in overectomized rats.
Method: thirty female Wistar rats with an average weight of 90-110g, were randomly assigned into three groups, consist of control, sham and swimming training. swimming time at first was 30 minutes for each session that daily increased 5 minutes until reached 60 minutes per day in second week and remained 60 minutes to end of training period (6 week). expression of estrogen receptors in fallopian tubes and uterus tissues were measured by immunohistochemistry assay. data analyzed by ANOVA and Tukey test at α≥0.005
Results: The mean levels of estrogen receptors expression in uterus were not significantly different between training with control group. But differences were significant between training and control groups with sham group (P<0.01). expression of estrogen receptors increased %78.43 in sham group and decreased %2.3 in training group in comparison to control group.
Conclusion: the results of present study indicated that six weeks' swimming training haven’t any effect on expression of estrogen receptors in overectomized rat uterus tissue.
