Materials and Methods: In a semi-experimental and applied study, 32 obese male rats of 6 months with Wistar breed with a weighted average of 332/28 Grams and standard deviation of 9 after 7 days of acquaintance with the laboratory environment were randomly divided into 4 groups of 8 (control, training, supplement and training-supplement). The training-supplementation and training groups underwent aerobic training for 6 weeks and 4 sessions in each week, according to the training protocol. Supplement and training- Supplements Groups also for 6 weeks and 4 meals every week, one hour before the start of training, 50 mg of curcumin per kilogram of body weight was gavage. 24 hours after the last training session, while fasting for 12 hours, all subjects were anesthetized with ketamine and xylazine solution and blood was taken from the posterior orbital sinus of the rats. The collected blood samples were immediately transferred to the laboratory to measure the variables. In order to analyze the data at the descriptive level, mean and standard deviation tests were used, and at the inferential level, the Shapiro-Wilk test was used to check the normality of the data, and the two-way ANOVA test was used to check the interaction effect of the groups. data analysis It was done with using spss software version 26 and at a significance level (P≤0.05). Results: The results of the research showed that a course of aerobic training and curcumin supplementation had a significant effect on TG and HDL of obese rats. It was also observed that a course of aerobic training and curcumin supplementation had no significant effect on TC and LDL of obese rats. Conclusion: The results showed that aerobic training and curcumin supplementation can be used simultaneously to improve the lipid profile of obese people, especially in HDL and TG indices Manuscript profile -

The aim of this study was the effect of endurance training and probiotic consumption on IL-18 gene expression in male rats with steatosis. Materials and Methods: In this experimental study, 32 rats (average weight 200-250 grams) were randomly divided into four groups (healthy control, modeled (steatosis) group, steatosis + probiotic group, and steatosis + probiotic + exercise group). Training groups for 8 weeks, 5 sessions every week, in the beginning week with a speed of 18 meters per minute, time of 10 minutes, and every week the speed of 1-2 meters per minute and the time was increased by 10 minutes, so that In the fourth week, the speed reached 22 meters per minute and the time reached 40 minutes. The groups receiving the supplement received 109 CFU/ml of Lactobacillus rhamnus GG by gavage daily for 8 weeks and 5 days a week. IL-18 gene expression in liver tissue was measured by Real-time PCR method. The data were evaluated using the statistical method of one-way analysis of variance and significance level (P ≥ 0.05). Results: The results showed that endurance training along with probiotic consumption significantly decreased IL-18 gene expression in rats with steatosis. Conclusion: It seems that performing endurance training along with probiotic consumption can have a greater effect than the effect of probiotic alone on IL-18 gene expression. Manuscript profile -

These substances include multifunctional performance-enhancing supplements, herbal supplements, and everyday vitamins. The main objective of this research is to find out how bodybuilding athletes' performance quality, muscle efficiency, and degree of satisfaction are affected by sports supplements. Materials and Methods: This study used a survey approach conducted in the field using a standardized questionnaire in conjunction with a descriptive-analytical research design. The study's statistical population included 131 participants who were among the top ten bodybuilding competitors at national championships. For statistical analysis, Friedman and linear regression tests were used after the data was collected. Results: The study results suggest that the majority of respondents concur that the use of sports supplements directly affects the functioning of body muscles. Moreover, the prolonged use of supplements that enhance weight and muscle volume has an increased effect on the performance of these athletes. The benefits of sports supplements are particularly noticeable throughout the second to fourth years of training for bodybuilding athletes as they continue to use these supplements. Conclusion: Evidence suggests that sports supplements have a discernible influence on muscle efficiency and the performance of bodybuilding athletes. Nevertheless, the use of sports supplements does not have a substantial impact on athlete satisfaction. Manuscript profile -

Materials and Methods: Examining the impact of short-term stress on depressive-like behavior and motor activity in rats is a crucial aspect of behavioral and neuroscience research. Short-term stress can influence rats' depressive-like behavior and decrease their motor activity. The purpose of this study was to investigate the effect of short-term stress on depressive-like behavior and the running index of male Wistar rats, as well as the relationship between the two variables. Results: Short-term stress significantly increased the 24-hour running index (P=0.01). The depression-like behavior of rats after stress induction did not show any significant difference. There was no significant relationship between the amount of running and depressive-like behavior (P=0.13). Conclusion: Based on the present findings, short-term stress caused an increase in the activity of male Wistar rats, which was not related to depressive-like behavior. Manuscript profile -

Strategic nutritional planning greatly benefits endurance athletes, particularly cyclists, as it underscores the critical role of macronutrient consumption in improving on the track/road performance and recovery. CHO is the primary energy source for prolonged cycling, as they are crucial for preserving optimal performance by preventing glycogen depletion and delaying fatigue. The efficacy of CHO is significantly influenced by their glycemic index (GI). High-GI CHO offers a rapid energy source that facilitates muscle glycogen resynthesis and sustained performance. Research suggests that high-GI CHO can increase muscle glycogen levels by up to 40% within four hours, underscoring their significance during and after pedaling. PRO, although not the primary energy source, is essential for synthesizing and repairing muscles, particularly during prolonged and intensive cycling. Incorporating essential amino acids to facilitate recovery is imperative, as they aid in muscle protein synthesis and mitigate muscle fatigue. Recent studies have demonstrated that PRO supplements, especially after pedaling, significantly enhance muscle glycogen and protein synthesis replenishment, leading to quicker recovery and improved performance during cycling sessions. The synergistic benefits of the combined supplementation of CHO and PRO are greater than those of each macronutrient alone. This combination improves endurance, delays fatigue, and ensures more efficient recovery by increasing glycogen storage, accelerating recovery, and enhancing muscle protein synthesis. The optimization of the benefits of these supplements is contingent upon the timing, dosage, and composition. Glycogen replenishment and muscle protein synthesis are optimized by consuming CHO and PRO immediately prior to and following exercise. This is particularly true for high-GI carbohydrates, such as glucose, and swiftly assimilated PRO, such as whey. In conclusion, this review provides practical recommendations for cyclists seeking to optimize their nutritional strategies by synthesizing findings from various studies. Cyclists can enhance their overall performance and achieve long-term athletic success by developing effective dietary plans that improve endurance, defer fatigue, and facilitate efficient recovery, facilitated by understanding the complex interactions between these macronutrients.

Materials and Methods: This quasi-experimental study used a pretest-posttest design with a control group. The statistical population of the research consisted of all male students (256 subjects) of primary school in municipal Zone 4 of Tehran. The sample in the present study was estimated to be 30 students in 3 groups using G*POWER to achieve a test power of 0.8 and an effect size of 0.80. Cluster sampling method was used to select students. In the first stage, 5 schools, 1 class from each school, and 6 students from each class were randomly selected as samples. They were randomly and equally divided into 3 groups of team games, individual games, and the control group. The Matson Evaluation of Social Skills with Youngsters-II (1983) was used to measure social skills, and The Barkley Deficits in Executive Functioning Scale—Children and Adolescents (BDEFS-CA) (2012) was used for executive functioning. In the present study, the designed experiment consisted of sixteen 60-min sessions (2 sessions per week); two types of experimental protocols including individual games and team games and also control conditions were used. Individual exercises included ten male students wherein each student performed the exercises with a coach. Team exercises included ten male students in the form of two teams who performed exercises as various activities and games. Results: By examining the results of difference in the means of the two intervention groups (team and individual exercises) and control group, it was found that in the sub-components of appropriate social skills, aggressiveness, and impulsive behaviors, the individual exercises group was more effective compared to the team exercises group (P<0.05). In the sub-components of non-social behaviors, superiority, high self-confidence, relationship with peers, and total social skills, the team exercises group was more effective compared to the individual exercises group (P<0.05). Besides, by examining the results of the difference in the means of the two intervention groups (team and individual exercises) and control group, it was found that the individual exercises group was more effective in the sub-components of self-organization, problem-solving, and self-motivation compared to the team exercises group (P<0.001). Yet, in the sub-component of self-management of time, self-control/inhibition, self-motivation, and total executive functioning, the team exercises group was more effective compared to the individual exercises group (P<0.001). Conclusion: Based on the results of the research, it can be concluded that both team and individual exercises lead to the promotion of social skills and executive functioning in students. Moreover, compared to individual exercises, team exercises are superior in enhancing students’ social skills and executive functioning. Manuscript profile
