The importance of brand equity is due to its strategic role in gaining a competitive advantage in the market. The purpose of this study was to assess the brand equity of Majid in comparison with Nike from the perspective of Iranian consumers. The research method was survey in terms of data collection and descriptive-correlation in terms of research method. The statistical population of this study was sport good consumers in the range of 18 to 45 years old. 384 sport good consumers completed an online questionnaire through random sampling. The reliability of the questionnaire was calculated based on Cronbach's alpha coefficient. Results of the Pearson correlation test revealed that there is a significant relationship between brand equity and its components in both brands. The results of the paired t-test, revealed that the Nike brand has higher brand equity than Majid brand according to the perspectives of Iranian consumers. Also, for the Iranian consumers, the quality of the brand is the most important element of brand equity.

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.

Purpose: The aim of this study was to investigate the acute effects of HIFT exercise, on creatine kinase (CK) and lactate dehydrogenase (LDH) in blood serum in overweight adult men. Method : Twenty-two untrained non-smoker overweight men (age, 42.9 ± 5.6 years; body mass, 94.2 ± 9.3 kg; body height, 178.9 ± 4.5 cm; and BMI, 29.04 ± 3.3 kg/m2) volunteered to participate in this study and performed a session of HIFT exercise with 80-85% HRmax consisting of three sets of 10 exercises. Blood samples were collected before and immediately after training to measure serum CK and LDH levels. Results: The HIFT protocol significantly increased serum CK (Pre: 114.6 U/L; Post: 124.3U/L; p< 0.05{t=-5.48, p=0.001}); Also, LDH had a significant increase (pre:213.4 U/L, post: 225.4U/L; p<0.05{t=-4.09, p=0.001}). Conclusion: It can be concluded that HIFT with AMRAP (as many repeats as possible) protocol will lead to a significant increase in some indicators of muscle damage such as CK and LDH levels in overweight men. This protocol can lead to muscle damage in overweight men.

Background: Research shows that new technologies have increased the tendency to use electronic sports in physical education activities. Studies on physical education activities and e-sports are relatively new and scattered in their focus. However, universities and professionals are growing interested in further research in this area. Aim: The purpose of this study is to systematically review the research done in e-sports and physical education. Materials and Methods: A search was made using EBSCO, Scopus, and Web of Science databases to collect information on the articles. More than 250 scientific articles from 2000 to 2024 were reviewed. The keywords used were: ("Internet sports" or "electronic sports" or "online sports" or "virtual sports" or "E-sport) and ("physical training" or "sports training" or "fitness training" or "Exercise instruction" or "Sports education" or "physical education"). After removing duplicates, 200 articles were screened by reviewing titles and abstracts, resulting in the exclusion of 100 articles that did not meet the inclusion criteria related to integrating electronic sports and physical education. The full texts of the remaining 100 articles were assessed, leading to the exclusion of 36 more articles due to insufficient data or lack of relevance, leaving 64 articles selected for detailed analysis based on their comprehensive coverage and relevance to the study. Then, the selected items were fully studied and finalized, and the items that were more complete than the others were chosen as references. Conclusion: The study identified critical organizational, technological, individual, and environmental factors influencing the implementation of e-sports. It also highlighted nine mediators’ factors essential for effective execution. Strategies like gamification, e-sport fitness challenges, cross-training, team building, health education, e-sport analysis, and smartening education were proposed to support the model's implementation. The expected outcomes of applying this model in physical education include improved cognitive skills, increased physical activity, enhanced social interaction, inclusivity, and technology skill integration. The study emphasizes that considering these factors and strategies will aid in successfully implementing the conceptual model.
