Aerobic training

The aim of this study was to obtain an insight into the influence of an interval progressive (pyramidal) aerobic training on serum lipid and lipoprotein profiles in San-Shou athletes. 13 national levels male San Shou player were (23.23 ± 2 years and 66.27±2.75kg,171.8 ± 2.8 cm in high and 22.42± 0.51 BMI) were voluntarily participated in this study. Blood samples (10ml) were taken from an arm vein before and after training program. All blood samples were prepared for glucose TC, TG, HDL-C LDL-c VLDL-C and some other blood factors and atherogenic indexes measurement. The results of this study show that there were a sig-nificant decrease in serum TG , VLDL-C concentrations and TC/HDL-C and LDL/HDL-C ratios and a significant increase in serum HDL-C levels after an interval progressive (py-ramidal)aerobic training for 14 weeks. The present date indicate that this training program was able to changes lipid and lipoprotein metabolism toward an cardiovascular indexes im-provement independent to any significant changes in TC and LDL-C levels.

Introduction: Prescribing the Adrenergic beta-Antagonists is very common in treating cardiovascular diseases. The aim of this study was to compare the effects of aerobic training in patients with coronary artery disease, prescribed two different types of beta-blockers (selective and non- selective) on the patient's lipid profile (Lipoproteins) and FBS (Blood Glucose). Materials and Methods : Sixty patients with coronary artery disease, aged 45-65 years, were compared in two groups of selective (n=36) and non-selective (n=24) users of beta-blockers. The training program consisted of 8 weeks of aerobic exercise on the treadmill (3 sessions per week, about 50 minutes per session, with an intensity of 40% to 60% of the heart rate reserve). Each study patient’s lipid profile and FBS level were obtained before the onset of the study and after the end of the intervention. The collected data were analyzed using repeated-measures Analysis of Variance (ANOVA). Results: In the selective group, lipid profile and FBS did not significantly change. In the non-selective group, FBS and triglyceride levels were significantly reduced after the intervention; however, HDL, LDL, and total cholesterol levels were not significantly changed (P>0.05). Conclusion: The results of this study showed that aerobic training in patients with CAD who used non-selective beta-blockers has more positive effects.

Purpose:  Multiple Sclerosis (MS) is an autoimmune disease which is on the rise in recent years especially in Iran. Although there has been much progress in MS treatment, there is no definitive cure for it. Considering high prices of prescription drugs and their serious side effects as well as, impact of this illness on function efficiency of individuals, it seems that exercise training is one of the effective, cheap, and without side effects methods, in improvement of the performance of MS patients. In this regard, the present study aimed to provide comprehensive information on the background and the latest studies conducted to evaluate the effect of various exercise trainings (resistance, aerobic, core stability, Pilates, and combined) on this disease.  Methods :  An electronic search from 1994 to 2022 was performed in the Magiran, SID, PubMed, Google Scholar, and Scopus databases to find published articles. The keywords were multiple sclerosis, physical activity, exercise, training, aerobics, resistance, combined, core stability and Pilates. Different articles were selected and reviewed according to relation with subject. Results: The results indicated that various exercise training with different duration, intensity, and frequency cause different adaptations in people. Furthermore, regular continuous combined exercise training can be more effective than one type of exercise training in improvement and reduction of the symptoms of MS disease. The mechanism of improvement in combined exercise training can be justified due to the benefits of concurrent use of two or more types of training protocols. Conclusions: It can be said that the combined use of exercise trainings is the most useful and effective method for these patients. However, more studies on the best combination of exercise trainings for MS patients should be done in the future.

Background: Physical activity affects the health of the body's organs through several processes. Apoptosis is one of the important cellular processes that play a role in maintaining the balance between cell death and tissue growth. Aim: The aim of the present study was to examine the previous findings regarding the effect of physical activity and exercise on apoptosis in order to obtain a relatively comprehensive knowledge of this effect by summarizing and analyzing the data. Materials and Methods: To collect the information of the articles, a search was made from PubMed, MEDLINE, SID, IranMedex, IranDoc, Magiran and Medlib databases. More than 80 scientific articles from 2000 to 2023 were reviewed. The keywords used were: physical activity, aerobic exercise, endurance exercise, apoptosis and cell suicide. After the review, finally 26 articles were selected. Then, the selected items were fully studied and finalized, and the items that were more complete than the others were selected as references. Conclusion: Physical activity and exercise, especially aerobic exercise, as a safe, cheap and accessible method, can reduce apoptosis through several mechanisms. The breadth of studies in this field, and the overlapping of many data, allows us to confidently introduce exercise and aerobic activity as one of the best methods of regulating body homeostasis and reducing apoptosis.

Background: Cardiovascular disease is a significant contributor to mortality in diabetic patients. Despite the potential benefits of concomitant and complementary training in diabetic patients, there is a paucity of evidence in this area.Aim: The objective of this study was to investigate the effect of aerobic training in conjunction with a hydroalcoholic extract of the fruit of Qaraqat on superoxide dismutase, glutathione peroxidase, total antioxidant capacity, and malondialdehyde in the heart tissue of male rats with type 2 diabetes.Materials and Methods: 24 male rats aged 8 weeks were diabetic with a high-fat diet (60%) and streptozotocin injection. They were randomly divided into four groups: (1) aerobic training (AT), (2) supplementation (Sup), (3) Aerobic training+ supplement (AT+Sup), and (4) diabetes control (Con). The training protocol included running on a treadmill at a speed of 5-24 m/min for 10-60 min, according to the principle of overload. Glucose, insulin, insulin resistance, and MDA, TAC, GPX, and SOD of heart tissue were measured. Statistical tests of two-way variance and post hoc Bonferroni were used using SPSS software at a significance level of P<0.005.Results A significant decrease in glucose levels, insulin resistance, and MDA (P<0.005) was observed in the intervention groups following eight weeks of training and supplement intervention, in comparison to the Con group. Also, the amount of insulin in Sup and AT+Sup groups exhibited a notable decline in comparison to Con and AT groups (P<0.005), as well as a substantial increase in the levels of SOD (P=0.001) and GPx (P<0.005), and TAC (P<0.005) was observed.Conclusion: Diabetes is associated with elevated MDA levels, which are reduced by aerobic training and supplementation. Furthermore, the administration of a training intervention and the utilization of a supplement have been demonstrated to elevate the levels of SOD, TAC, and GPx.
