Abstract

Background and objectives: Elderly is characterized by decreased cardiac function, which is widely associated with mitochondrial failure in cell death. Elderly causes heart apoptosis. Although the old heart is vulnerable to apoptosis, physical training and some supplements through different mechanisms could be effective in reducing apoptosis. The present study aimed to investigate the effect of interval training on some apoptotic parameters of Bax and Bcl2 cardiomyocytes in old female rats.
 
Methods: In an experimental study, 49 Wistar female rats (2 years old) were randomly assigned into 7 groups: control, saline, curcumin, moderate intensity training, moderate intensity training + curcumin, high intensity training, high intensity training + curcumin. The experimental groups received gavage doses of curcumin 30 mg / kg body weight three days a week via. The saline group also received the same amount of saline. Training groups had moderate and severe exercises on the treadmill for eight weeks, and three sessions per week. Forty-eight hours after the last training session and gavage, the animals were killed and their heart tissues were isolated to determine the levels of Bax and Bcl2.
 
Results: The results indicated that interval training and curcumin consumption could significantly increase the levels of Bcl2 and BAX and the BAX / Bcl2 ratio, the amount of which depends on the intensity of training. Moreover, the combination of training and curcumin had an antagonistic effect.
 
Conclusion: According to the results, physical activity and curcumin separately have a protective effect on the heart tissue; however, these two interventions do not enhance each other’s effect. Hence each one is suggested to be used separately.

Abstract

Background and Objective: Autophagy is a genetically and evolutionarily conserved the programmed process that destroys long-lived cellular proteins and organelles. This study aimed to evaluate the effect of eight weeks of strength training with alpha-lipoic acid supplementation on LC3-I and P62 in elderly diabetic rats.
Material and Methods: In this experimental study, 35 old male Wistar rats were randomly divided into 5 groups (healthy control, diabetic, diabetic + strength training, Diabetic + supplement, Diabetic + strength training + supplement). First, the rats became diabetic and had a fatty liver. Strength training program in 10 weeks performed. Alfa-lipoic acid supplement was also injected 3 days a week. At the end of the training period and tissues were removed and the expression of LC3-I and P62 were measured by RT-PCR. For data analysis, a one-way analysis variance test was used for comparison between groups was considered (P<0/05).
Results: The result showed mRNA LC3-1 has increased and this change is more in the diabetic group. (P=0.001) and  despite the decrease in P62 gene expression, we did not see a significant difference between the control group and the diabetic in the training group with and without supplementation.However, no significant difference was observed between training methods and supplementation with exercise. Also, resistance training in combination with alpha-lipoic acid supplementation had a significant effect on reducing P62 content between control and experimental groups. (P=0.001).
Conclusion: Alfa-lipoic acid supplement with anti-oxidant and anti-inflammatory effect along with exercise can play an important role in improving fatty liver in elderly type 2 diabetic rats.
