However, there are conflicting results regarding the effects of resistance training on Neural cell adhesion molecule (NCAM) gene expression. Therefore, the present study aimed to investigate the effect of 4 weeks of increasing resistance training on NCAM gene expression in the gastrocnemius muscle of healthy male rats. Materials and Methods: In an experimental trial, 12 young male rats were randomly divided into 2 groups of 6, including the control and resistance training groups. The training group performed increasing resistance training 5 days a week for 4 weeks on a special rodent ladder. Forty-eight hours after the end of the training intervention, the rats were sacrificed and the gastrocnemius muscle tissue was extracted for the expression of the NCAM gene using the real-time method. Results: resistance training in the neuromuscular junction, gastrocnemius muscle increased NCAM gene expression (P=0.036) compared to the control group. Conclusion: Four weeks of resistance training can improve skeletal muscle function by increasing NCAM gene expression at the end of muscle fibers. resistance training Neural cell adhesion molecule genehttp://jspac.etb.iau.ir/en/Article/Download/45727

Materials and Methods: 17 judokas including nine men (age: 19.94±1.68, weight: 68.57±10.03 and height: 176.77±7.44) and eight women (age: 25.62±3.48, weight: 62.70±40.0 and height: 160.7±87.31), voluntarily participated in semi-experimental study. Subjects performed Uchi-kumi training until exhaustion in two separate sessions as two active and passive recoveries with a time interval of 48 hours. Blood lactate was measured before, immediately, 5 and 10 minutes after exercise. In passive recovery, subjects sat on a chair, and in active recovery, uchi-kumi training was performed without a training opponent. Data were analyzed by analysis of variance with repeated Measures and t-test. Results: After 5 minutes, lactate reduction was significant only in active recovery for men (P=0.001) and women (P=0.001); But in 10th minute of recovery, lactate reduction in both active states for men (P=0.001) and women (P=0.048) and passive states for men (P=0.001) and women (P=0.001) It was significant. In addition, the changes between men and women were similar in both cases. Conclusion: An increase in blood lactate after uchi kumi training was expected; however, passive recycling required at least 10 minutes. Therfore, 5 minutes of Uchi Kumi training without a training opponent, regardless of the effect of gender, accelerated the recovery and prepared the judokas to participate in the next competition.

The aim of this study was the effect of aerobic training and probiotic consumption on gene expression of IL6 liver tissue in rats with non-alcoholic fatty liver. Materials and Methods: In this experimental study, 32 male Wistar rats, 200-250 gr, were randomly divided into 4 groups: healthy group, modeled group (steatosis), steatosis + probiotic group, steatosis + probiotic + training group. To create a fatty liver model, tetracycline at a dose of 100 mg / kg at a volume of 1.5 cc per rat was gavaged daily for two weeks. The main training program was for eight weeks/3times per week. In the first week with a speed of 18 meters per minute, the time started 10 minutes and every week quickly, 1-2 meters per minute and time was added to 10 minutes so that in the fourth week the speed to 22 meters per minute and time to 40 minute has arrived. Probiotic groups received 109 CFU / ml of Lactobacillus ramensus by gavage daily for 8 weeks and 5 days a week. 48 hours after the last training session, 10 ml of blood was taken directly from the hearts of rat to test for total cholesterol (TC) and liver tissue samples were taken to test for IL6 gene expression. One-way analysis of variance and Tukey post hoc test was used P≤0.05. Results: There is a significant difference between the IL-6 gene variable in the groups (P=0/000), Induction of fatty liver in rats was associated with a significant increase in interleukin-6 gene levels, these changes were significantly reduced after taking probiotics (P=0/000), Also probiotic consumption with aerobic training had a significant reduction compared to other groups. However taking probiotic with aerobic training had no significant effect on TC of rats with non-alcoholic fatty liver (P=0/306). Conclusion: Probably, performing aerobic training along with taking probiotic can have a better effect in controlling non-alcoholic fatty liver disease.

Materials and Methods: In this semi-experimental research that was conducted in the field, 20 male students aged 16 to 18 years, whose anxiety level was less than 10 using the Kettle test, were selected and randomly divided into two groups of football practice and running. . The subjects ran and played football for 8 weeks and their anxiety level were measured again. In order to describe the demographic characteristics of the research, descriptive statistics were used, and in order to analyze inferential statistics, correlation t and analysis of covariance were analyzed using SPSS software version 21. Results: The mean and standard deviation of the anxiety score in the pre-test and post-test stages in the running group were 5.5 ± 2.66, 3.75 ± 2.38 and in the football game group 5.6 ± 2.42, 2.39 respectively. It was ± 4.55. The results showed that an eight-week training period of running and playing football has reduced the level of students' anxiety. Also, running caused a greater decrease in anxiety than the football training group (p≤0.01). The results showed that running and playing football significantly reduce anxiety symptoms. Conclusion: The mechanisms through which exercise produces these effects probably involve a combination of biological and psychological factors. Physical activity may also be beneficial in reducing symptoms of comorbid mental illnesses and the risk of physical health complications over time. Promoting physical activity can be a way to prevent or treat anxiety disorders with a wide range of benefits. However, before these approaches can be fully implemented in mental health services, further research will be necessary to address important gaps in the background literature.

Since sports activity is known to protect the heart, the aim of the present study was to investigate aerobic exercise and the effective substance crocetin on the expression of Myod gene in the heart tissue of an experimental model of elderly prediabetic rats. Materials and Methods: In this experimental trial, 25 elderly female c57bl6 male mice with prediabetes (20 mg/kg peritoneal injection) aged 14-16 weeks and weighing 30-35 grams were divided into 5 healthy control groups, prediabetic, prediabetic + aerobic exercise, pre-diabetic + crocetin, pre-diabetic + aerobic exercise + crocetin were divided. aerobic training was performed for eight weeks, five sessions per week. Mice received crocetin 30 mg/kg/day by intraperitoneal injection. Myod expression was measured by Real Time PCR method. To analyze the data, one-way analysis of variance and Tukey's post hoc test were used (P≥0.05). Results: Myod gene expression was significantly decreased in the prediabetic group compared to the healthy group (P=0.01). Myod gene expression was significantly higher in the pre-diabetes group + aerobic exercise + crocetin supplement and diabetes group + aerobic exercise + crocetin supplement than other groups (P=0.01). Conclusion: It seems that intermittent aerobic exercise and crocetin both alone and simultaneously are effective in improving Myod gene expression in prediabetic heart tissue. Therefore, the use of periodic aerobics and crocetin n is recommended in pre-diabetes conditions of old age Aerobic exercise crocetin Myod heart elderly pre-diabeteshttp://jspac.etb.iau.ir/en/Article/Download/46523
