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.
