      Background: This study was conducted to evaluate the effect of eight weeks of High-Intensity Interval Training (HIIT) on adiponectin and AST, ALT, and ALP enzymes in obese and overweight boys. Materials and Methods: Subjects were 22 boys aged 12-14 years old, who were randomly assigned to experimental and control groups. Experimental group: mean weight 80.08 ± 16.08, Vo2max was 36.56 ± 2.49, and BMI was 30.27 ± 5.9 and control group: mean weight 67.91 ± 7.95, and Vo2max was 44.4 ± 2.75, 38 and BMI of 60.26 ± 6.3. The experimental group performed eight weeks of HIIT training with 80% HRR intensity at 10 turns of 60 seconds, with 60 seconds rest on exercise bikes for 3 days a week. Blood samples were taken 24 and 48 hours before and after the training, ANCOVA was used for data analysis using SPSS 21 software at a significant level (p <0.05). Results: The results showed that HIIT reduced the levels of Adiponectin and AST and ALP enzymes, but this was not significant (P≥0.05). This exercise also reduced ALT and fat percentage and increased Vo2max in subjects, with changes in all three variables significant (P≤0 / 05). Conclusion: It seems HIIT can reduce the percentage of fat and ALT enzyme in children, which can help prevent many metabolic diseases. Also, HIIT can play a role in liver health in overweight and obese children. Manuscript Document

      Dear Editor Regular exercise and physical activity are effective preventative measures for over 25 chronic medical conditions, including cardiovascular disease and premature death. According to the World Health Organization, physical inactivity is the fourth leading risk factor for death, killing about 3.2 million people annually (1). It is accepted that an individual's behavior is due to three factors: biological/genetic influences, environmental influences, and/or the interaction between biological and environmental factors. There are biological/genetic differences in sexual activity that are distinct from environmental influences on activity (2). Today, the development of genetic evaluation methods throughout the human genome has made it possible for sports scientists and physicians to study genetic factors that play a role in regular physical activity and exercise in preventing chronic diseases. Studies have shown that there is an interaction of the gene × physical activity in reducing the risk factors for type 2 diabetes, obesity, and cardiovascular disease. In the following, we will review several studies in this regard. Manuscript Document

      Background: Reactive oxygen species are produced in response to strenuous, prolonged exercise, such as swimming, which results in cell damage. The aim of this study was to compare the effect of antioxidant and coenzyme 10Q supplementation on some indicators of muscle injury in water polo boys. Materials and Methods: The 24 boy water polo players with at least 5 years of training experience and in the age range of 17 to 23 years were randomly divided into three groups )8 people (of vitamin C, coenzyme Q10 and control. Subjects in the vitamin C group (500 mg of vitamin C tablets) and subjects in the coenzyme Q10 group (300 mg of coenzyme Q10 tablets) were consumed daily with food for two weeks. Trainings were performed for two weeks, 6 sessions per week and 90 minutes per session. Evaluation of CK, LDH and AST indices in the state of at least twelve hours of fasting was performed in three stages: previous, immediately and 24 hours after the completion of the protocol. One-factor analysis of variance test with repeated measures was used. Results: The results showed that CPK decreased significantly after fourteen days of supplementation in coenzyme Q10 group and increased significantly 24 hours after the last training session and in vitamin C group after fourteen days of supplementation and 24 hours after the last training session increased significantly. There was no significant difference in LDH and AST levels between the groups (P <0.05). Conclusion: It seems taking coenzyme Q10 supplements may possibly reduce some indicators of muscle damage after water polo training. Manuscript Document

      According to the investigation, Lipokines are a kind of bioactive compounds, derived from adipose tissue deposition, which manages multiple molecular signaling pathways. In recent years, 12,13-dihydroxy-9Z-octadecanoic acid (12,13-diHOME), an Oxylipin, has become increasingly important in the scientific literature. An increase of 12,13-diHOME in circulation was associated with an improvement in metabolic health, and the action of this molecule seems to be mediated by brown adipose tissue (BAT)(1). In fact, Oxylipins are oxidized metabolites of long-chain polyunsaturated fatty acids (PUFAs). PUFAs may be received immediately from the weight loss program or from the metabolism of linoleic acid and α-linolenic acid(2). Research indicates that Oxylipins are present in every tissue, urine and blood(3). Linoleic acid may be metabolized through cytochrome P450 (CYP) in order to produce 12,13-diHOME(4). Circulating concentrations of BATokine 12,13-dihydroxy-9Z-octadecenoic (12,13-diHOME) in rodents and humans have been shown to be elevated following exposure to cold and exercise. In other words, in mice, administration of 12,13-diHOME increased fatty acid absorption by brown/beige adipocytes and skeletal muscle after a session of moderate-intensity training, and in rodents using the same training protocol. Furthermore, investigation suggests that circulating 12,13-diHOME is associated with an increase in mitochondrial respiration capacity in the skeletal muscle. This information improves the opportunity that will increase in circulating 12,13-diHOME with exercising capabilities to assist expand the respiratory capacity of a training skeletal muscle and might increase exercise potential(5,6).

      Background: Exercise training plays an important role in combating Alzheimer's disease. Present study aimed to investigate the effect of 12 weeks aerobic training on the levels of tumor necrosis factor alpha (TNF-α) in the hippocampus and prefrontal cortex, and also depression in rats with Alzheimer's disease. Methods: The 40 Wistar rats were divided into four equal groups including saline (S), saline +training (ST), training +STZ (AT) and STZ (A). Alzheimer's was induced by injection of 3 mg/kg streptozotocin (STZ) into the ventricles of brain. The aerobic training program (each session lasted 30 minutes with 10-12 meters per minute speed) performed for 12 weeks and five sessions per week on a treadmill. The 48 hours after last training session, brain tissue (hippocampal and prefrontal cortex areas) was removed and TNF-α levels were measured by ELISA method. Data were evaluated using the statistical method of analysis of variance at a significant level (P <0.05). Result: TNF-α levels in the hippocampus were significantly higher in group A compared to S (p= 0.010), ST (p= 0.014) and AT (p= 0.041) groups. Moreover, no significant change was observed for TNF-α levels in prefrontal cortex in different groups (p= 0.276). In addition, a significant increase in inactivity duration (FST) was observed in group A compared to other groups (p <0.05) and also a significant decrease in sucrose preference (SPT) was observed in group A compared to other groups. (p<0.05). Conclusion: The present study findings indicated that, the positive effects of aerobic training in rats with Alzheimer's disease are exerted partly by modulating the levels of inflammatory factors such as TNF-α in the brain especially the hippocampus.
