The purpose of this study was to investigate the factors affecting the sudden buying of sportswear in sports stores in Mazandaran, Iran. This applied research has been done by descriptive-survey method. The statistical population of the study was the customers of a reputable sports store in Mazandaran province. 385 customers were selected through  available sampling method. A valid and reliable researcher-developed questionnaire was used for data collection, and structural equation modeling (SEM) was conducted for data analysis and hypotheses test. The results showed that the store environment (light, color, music, fragrance) has a positive effect on the sudden buying behavior of store customers. Moreover, the findings demonstrated that layout and physical appearance (Product availability, booth guide, product layout, building appearance, and staff coverage), as well as facilities available in the store and ancillary services (cafes and restaurants, amusement parks, child care centers), affect the psychological characteristics of customers' sudden buying behavior. By focusing on the research findings, the managers of sports stores can have a positive impact on customers’ sudden buying and improving the selling approaches.

Purpose: Skin is the most important organ of the body and maintains its integrity is critical in good health. Severe skin damage is life-threatening and repairing restores its tissue integrity and delay in it endangers health. According to the importance of wound healing and the fact that not treated wounds may decrease quality of life, many studies have investigated the effect of some natural and chemical substance on the length and quality of wound healing to find out beneficial interventions that rapidly and economically treat it. This review aimed to describe the physiology of cutaneous wound healing and some negative and positive factor with a focus on exercise. Methods: An electronic search without any time limitation was performed on the PubMed, Google scholar and web of science databases to find published articles in English. The keywords were wound healing, exercise, and physiology. According to relation to subject, similarities, and differences 48 articles were selected and reviewed. Results: wound healing is a complicated physiology process that consists of four consecutive overlapping stages. Disruption in each stage disturbs wound healing. Many chemical and herbal compounds are used to speed up wound recovery due to their anti-inflammatory property. Exercise is one of the effective factors in wound healing and many studies evaluated effect of different protocol of exercise on it. The results of studies show that aerobic exercise due to its anti-inflammatory and antioxidative effect is a beneficial method in shortening the length of wound healing, especially in aged, fat, and diabetic individuals. Conclusion: Moderate intensity aerobic exercise as a complementary medicine is a good intervention in the treatment of impaired and chronic wounds.

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: Adropin is a newly identified bioactive protein that is important in energy hemostasis and vascular endothelial function. Aim : The purpose of the present study was to investigate plasma levels of adropin and nitrite/nitrate (NO), in elderly treated hypertensive subjects at baseline and follow-up after 6 weeks of high-intensity interval training (HIIT). Material and Methods: Forty-four elderly participants with treated hypertensives (age 61.09±5.82 years, 25 male and 19 female, BMI= 25.7±1.31 kg/m 2 ) were randomly assigned to either the high-intensity interval training (HIIT) or control group. The HIIT group received an intervention consisting of 10 intervals of 1.5 min at 85% to 90% of their heart rate reserve (HRR), separated by 2 min of rest at 50% to 55% of their HRR, in three sessions per week for a duration of six weeks. Plasma levels of adropin and NO were measured using enzyme-linked immunosorbent assay. The statistical analysis was performed by two-way repeated ANOVA to determine differences between groups and Pearson’s correlation coefficient to determine correlation. Results: The results showed that, following the six-week HIIT intervention, the plasma levels of adropin and NO significantly increased when compared to both control group ( P = 0.0016) and the baseline ( P = 0.0003) measurements. Peak oxygen consumption was increased after exercise training compared to the control group ( P =0.005). Δ adropin in the HIIT group showed a positive correlation with increased Δ NO (r= 0.707, P = 0.002) and Δ VO 2 peak (r= 0.836, P = 0.001), and a negative correlation with Δ DBP (r= 0.643, P = 0.025) and Δ SBP (r= 0.691, P = 0.013). Conclusions: The study findings suggests that HIIT can enhance both blood pressure and cardiorespiratory fitness. The observed increase in plasma level of adropin may have contributed to reduction of blood pressure by promoting nitric oxide production.

Background : Work-related musculoskeletal disorder is the most important occupational disease that threatens the health of employees. Aim: The aim of this study was to investigate the relationship between workers' posture and musculoskeletal disorders. Materials and Methods: Eighty-two male and female workers working in a home appliance factory participated in this cross-sectional study. Musculoskeletal disorders were investigated using Nordic questionnaires. Posture evaluation was performed to measure the angles of forward head, rounded shoulders, and thoracic kyphosis using photogrammetry. Craniovertebral, shoulder, and thoracic kyphosis angles were photographed during the work and then measured using ImageJ software. Data analysis was done using SPSS 26 and Spearman's correlation test at a significance level of 0.05. Results : A significant relationship between the craniovertebral angle and musculoskeletal disorders in the last twelve months was observed in the cervical region ( P <0.001). Also, a significant relationship was observed between the kyphosis angle and musculoskeletal disorders in the last twelve months in the upper back and lower back ( P <0.001). Conclusion : The results showed that the workers’ posture during work is correlated with the prevalence of musculoskeletal disorders. Therefore, it is suggested to pay attention to ergonomic principles during work to maintain and improve the physical health of workers.
