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 objectives: It has been reported that deep-fried oils (DFOs) used in the preparation of fast foods can affect the immune system. On the other hand, regular physical activity and proper nutrition, in addition to affecting physical function, have a tremendous impact on the immune system. The aim of the present study was to investigate the anti-inflammatory effects of aerobic training (T) and octopamine (O) consumption in the heart tissue of rats fed DFO.
Methods: In this experimental study, 25 male Wistar rats with mean age of 20 weeks old and weighing 300- 350 were purchased and divided into 5 groups of 5 rats, including: 1) control, 2) DFO, 3) DFO+T, 4) DFO+O and 5) DFO+T+O. During four weeks, groups 2- 5 received DFO by gavage; groups 3- 5 ran on treadmill (with speed of 50% Vo2max in the first week which reached 65% Vo2max in the last week) five sessions per week and 20 minutes per session and groups 4-5 received 81 μmol/kg octopamine supplement peritoneally for 5 days per week. Nuclear factor kappa B (NF-κB) and tumor necrosis factor-alpha (TNF-α) gene expression were measured in heart tissue.
Results: DFO significantly increased NF-κB (P=0.005) and TNF-α (P=0.001) gene expression levels; T significantly on decreased NF-κB (P=0.01) and TNF-α (P=0.007) gene expression levels; O consumption significantly decreased NF-κB (P=0.001) and TNF-α (P=0.001) gene expression levels; however, the interactive effects of T and O consumption on NF-κB (P=0.57) and TNF-α (P=0.20) gene expression levels was not significant.
Conclusion: It seems that T and O consumption alone have anti-inflammatory effects on the heart tissue of rats fed DFO, however T and O do not have anti-inflammatory interactive effects.
