Abstract
Background and objective: Aging and menopause are associated with decreased antioxidant function, however, the role of exercise and estrogen consumption in the health of these people has been shown. The aim of the present study was to investigate the interactive effect of aerobic training (AT) and estrogen (Es) on serum levels of catalase (Cat) and glutathione peroxidase (Gpx) enzymes in ovariectomized rats.
Material and Methods: In this experimental study, 45 ovariectomized rats were randomly divided into 5 groups of 9 rats, including (1) control (C), (2) estrogen solvent (sesame oil) (Sh), (3) AT, (4), Es,and (5) AT+Es. Rats in groups 3 and 5 were trained for eight weeks and three sessions, and groups 4 and 5 randomly received 30 micrograms of estradiol valerate daily for eight weeks. Data analysis was analyzed using one-way analysis of variance and Tukey’s post hoc test at the significance level of 0.05.
Results: Cat levels in the AT (P= 0.006), Es (P= 0.005) and AT + Es (P = 0.001) groups were significantly higher than the control group. Cat levels in the AT + Es group were also significantly higher than in the Es group (P = 0.01). Gpx levels in the AT (P = 0.001), S (P = 0.001) and AT + Es (p = 0.001) groups were significantly higher than the control group, while in the S (P = 0.001) and AT + Es (P = 0.001) groups, they were significantly higher than the AT group.
Conclusion: It seems that aerobic training combined with estrogen consumption synergistically improves the function of the antioxidant system in ovariectomized rats. However, it seems that the signaling pathway of interventions requires further study.

Abstract
Background and objectives: Aging is a natural phenomenon associated with a decrease in physical fitness factors and increases in chronic pain. The present study aimed to investigate the effect of High Interval Intensity Training (HIIT) and Moderate Intensity Continued Training (MICT) with Citrus Aurantium (CA) consumption on pain threshold and motor balance in elderly rats.
Material and Methods: Forty-nine elderly rats were randomly divided into 1) control, 2) MICT, 3) HIIT, 4) MICT+CA, 5) HIIT+CA, 6) CA and 7) sham groups. Groups 3 and 5 performed HIIT at a speed of 25-25 m/min, and groups 2 and 4 performed MICT at a speed of 25-20 m/min; also, groups 4-6 received 300 mg/kg/day CA peritoneally. The pain and motor balance tests were evaluated using a hot plate and rotarod devices respectively. The Kolmogorov-Smirnov test was used to investigate the normal distribution of findings and one-way ANOVA with Tukey’s post- hoc tests was used to analyze of findings (P≤0.05).
Results: CA, MICT, HIIT, MICT+CA, and HIIT+CA significantly increased pain threshold and motor balance (P<0.05); MICT+CA (P<0.05) and HIIT+CA (P<0.05) significantly increased pain threshold compared to CA, MICT, and HIIT, and HIIT+CA significantly increased pain threshold compared to MICT+CA (P<0.05).
Conclusion: Although CA, MICT, and HIIT alone can enhance pain threshold and motor balance nevertheless it appears that MICT+CA and HIIT+CA have a better effect on the increase of pain threshold, so the effects of HIIT+CA can be higher than MICT+CA.

Abstract
Background: Obesity carries great risks related to health, such as the development and progression of chronic inflammation and obvious metabolic disorders. This study aimed to examine the effect of eight weeks of moderate-intensity resistance training with garlic supplementation on the lipid profile in overweight women.
Methods: The present research was a semi-experimental study and the participants were 60 overweight women from Gachsaran City with (body mass index: 28/45±6/72) who were randomly divided into four groups (n = 15): supplemental exercise, placebo exercise, garlic supplemental, and placebo. Two training groups performed moderate-intensity resistance training for eight weeks and three sessions per week. One day before the start of training and 48 hours after the last training session, blood samples were collected to measure total cholesterol (TC), triglyceride (TG), LDL-C, and HDL-C variables. Data were analyzed by one-way ANOVA and LSD post-hoc test.
Results: Findings showed that there is a significant decrease in the serum levels of TC, TG, and LDL-C and a significant increase in HDL-C (P<0.05) serum levels in three groups of supplemental exercise, placebo exercise, and garlic supplemental compared to the placebo group.
Conclusion: Moderate-intensity resistance training with and without consuming garlic improves overweight women's lipid profile, and when exercise is accompanied by consuming garlic, the amount of these changes and improving the lipid profile is greater.
