 The objective of this narrative review is to systematically evaluate the combined effects of aerobic exercise and fasting protocols on obesity control in women.

Methods and Materials:

 A comprehensive literature search was conducted using databases such as PubMed, Scopus, Web of Science, and Google Scholar. Studies included involved adult women with overweight or obesity, investigating the effects of aerobic exercise, fasting protocols, or their combination on weight loss and metabolic health. Data were extracted on study design, participant characteristics, interventions, outcomes, and key findings. The quality of the included studies was assessed using standardized tools, and a descriptive analysis approach was employed to synthesize findings.

 The review found that both aerobic exercise and fasting protocols individually promote significant weight loss and improve metabolic health markers in obese women. Combined interventions lead to greater reductions in body weight and fat, enhanced insulin sensitivity, and improved lipid profiles compared to either strategy alone. For instance, combining aerobic exercise with intermittent fasting resulted in weight loss of up to 10% over 12 weeks, and a significant reduction in body fat percentage. Improvements in inflammatory markers, such as a reduction in CRP levels by 20%, were also noted. The synergistic effects are attributed to complementary mechanisms, including enhanced energy expenditure, improved metabolic flexibility, hormonal regulation, and reduced inflammation.

 Combining aerobic exercise with fasting protocols is a highly effective strategy for obesity control in women, leading to significant and sustained weight loss, improved body composition, and enhanced metabolic health. These interventions are supported by robust mechanistic insights and practical benefits, making them a valuable addition to comprehensive obesity management programs. Further research should focus on long-term effects, optimal protocols, and diverse populations to refine and expand the application of these combined approaches.

 the aim of the present study was to investigate the effect of cumin intake following partial sleep deprivation (PSD) on the oxidation of carbohydrates and fats and some cardiorespiratory indices in student-athletes.

The present study was quasi-experimental and the research design was cross-sectional. The statistical population included all female student-athletes of Imam Khomeini International university (Age: 18-25 years), of whom 8 students were chosen based on convenience sampling method (Age: 20.01± 53 0.53; height 163.50± 6.57 cm;, weight 56.54± 2 2.54 kg; body mass index 21.19 ± 1.85 kg / m2; maximum oxygen consumption 87 58.30±5.5 kg / min and heart rate 93.63 ±5.15 beats per minute). The main group consisted of 8 subjects who were initially tested as a control group; they were then tested again as placebo and supplement groups after a seven-day wash out period, respectively. PSD was performed for 4 hours the night before the test. Exhaustion was measured and recorded by Bruce treadmill test; cardiorespiratory parameters, carbohydrate and fat oxidation were analyzed by gas analyzer.

The results suggested that carbohydrate oxidation increased at the time of maximum oxygen consumption (Vo2max) in the cumin supplement group (p≤0.05). Carbohydrate oxidation and respiratory exchange ratio also increased at the time of anaerobic threshold and Vo2max in cumin supplement group (p≤0.05).

In summary, it can be said that taking cumin pills improves the performance of sleep deprived athletes.

The purpose of this study was to analyze destructive leadership and its consequences in schools in Tehran province. The present study is qualitative research that was conducted using the interpretive phenomenology strategy and Colaizzi's analysis method. In line with this goal, the perceived experiences of teachers regarding the destructive behaviors of school principals and their consequences were explored. The research field was primary and secondary schools in Tehran province. Fourteen interviews were conducted using purposeful and snowball sampling methods through semi-structured interviews with teachers and school assistants. The duration of the interviews was between 40 and 60 minutes. After analyzing the data, 35 components related to destructive leadership behaviors were discovered, which were classified into 8 main themes of destructive behaviors: dominance and mastery, narcissism, unfavorable political behavior, offensive behavior, lack of empathy, unfair behavior, micromanagement, resistance to change, and lack of responsibility. Also, 25 components related to the consequences of destructive leadership were extracted and categorized into 8 main themes. Such an atmosphere leads to a decrease in job motivation, an increase in interpersonal tensions, a decrease in cooperation and interaction, a lack of professional development, a decrease in interpersonal trust, a lack of completion of the teaching staff, a decrease in physical and mental health, and the poisoning of the school environment. The results of the research confirm the occurrence of destructive behavior of managers in Iranian schools. By paying attention to teachers' voices, this research tries to increase awareness about destructive leadership in the educational environment and to consider the need to improve leadership mechanisms in educational organizations.

The aim of this research was to identify factors influencing the development of sports entrepreneurship, with an emphasis on sports startups in the country. The research employed a mixed-method approach and was applied in nature. In terms of data collection and information gathering, it was field-based and descriptive-survey research. The statistical population of this study included members of the board of directors of sports startups, experts in the field, and specialists. The research samples were selected purposefully, with 38 participants in the qualitative section and 208 in the quantitative section, based on the research objectives and reaching theoretical saturation.

The researcher then reviewed and coded each interview individually. Additionally, in the quantitative section, structural equation modeling (SEM) using PLS software was employed. The results of the coding process revealed that the factors influencing the development of sports startups include five components: supportive factors, advertising, technology, market awareness, and culture. In the quantitative section, the identified factors were presented to the research sample in the form of a closed questionnaire. The quantitative results also indicated that the five identified factors have a significant impact on the development of sports startups. The factors identified in this research should receive serious attention from sports managers to foster the growth of sports startups.

The gap between theory and practice has always been a subject of debate among theorists and practitioners. Practitioners frequently critique the limited applicability of theory in real-world organizational settings, while researchers express concern over the perceived lack of theoretical grounding in Human Resource Development (HRD) practice. In response to this critical issue, actionable knowledge development has emerged as a key area of investigation. The present study aims to address this gap by proposing a model for the development of actionable knowledge among HRD practitioners. Employing a qualitative research approach, the research data were collected through semi-structured interviews with a sample of 24 HRD practitioners from Iran’s administrative system. To this end, thematic coding strategies (open and axial) were used to analyze the interview data. The findings revealed a cyclical model of actionable knowledge development, characterized by six key stages. These stages revolve around two axes: "knowing" and "doing." The "knowing" axis encompasses three stages: Receiving, adapting, and searching for knowledge. The "doing" axis, conversely, comprises three stages: Legitimizing, reconfiguring, and rendering knowledge into practice. By fostering attention to this cyclical model, individual and organizational development can be facilitated. Furthermore, this model has the potential to bridge the gap between the social system of science and the social system of practice, ultimately promoting the formation and application of practical knowledge for HRD practitioners to effectively address everyday challenges.

The implementation of the Fundamental Reform Document of Education (FRDE) has been one of the significant issues of the education system in our country in the last decade. FRDE, similar to all educational policies and reforms, is affected by the adaption process and is not necessarily implemented according to policymakers’ intentions.The aims of this study is to understand and explain the meaning made by school principals of their role during the implementation of FRDE and investigates how to implement the transformation document. This qualitative study was conducted using the phenomenology method and based on the cognitive framework of sensemaking. Data was gathered through semi-structured and in-depth interviews with 8 public high school principals in four district 3, 6, 7, and 13 of Tehran. Participants were selected using purposive sampling. Data analysis method of Miles et al. (2014) led to the formation of three main theme categories “ambiguty”, “documentary”, and “individual and situational factors”. Finding illuminates, the ambiguity of FRDE’s text and how it is transitioning to practice. The requirement to act in such a situation leads principals to make another sense of their role and they perceive themselves as documenters. In light of the findings, forming this meaning was affected by individual factors including same-old and to-no-avail attempts, as well as situational factors including the extent of applying, rules and regulations, and value position. According to the findings, despite the efforts made to implement the FRDE in schools, the main purpose of the implementation of it has not been achieved. The attention of policymakers to the factors that shape sensemaking can help in designing educational policies and more effective implementation.

Most of the administrators of the universities are faculty members and they have not received the necessary training and have not been evaluated in an organized manner. Considering the importance of paying attention to competency in the selection of efficient and effective administrators and considering the critical role of universities in the society, the aim of the current research is to development and validation a general competencies model for public universities’ administrators in Tehran. A qualitative method was used in this research; Thematic analysis method was used to design the competency model and Delphi technique was used to validation the designed model. The sample was the administrators of the public universities in Tehran, and semi-structured interviews were conducted with 27 of them. After the qualitative analysis of the implemented interviews, the primary model was extracted using thematic analysis. Delphi technique was used to validating the extracted model, and the final competency model, which consists of 12 competencies, was formulated with the opinion of experts. Competencies were classified into three general categories: managerial competencies, interpersonal competencies, and personal characteristics. Managerial competencies include leadership, organizational awareness, problem solving, planning and organizing, and supervision and control; Interpersonal competencies include communication skills, networking and negotiation and persuasion, and personal characteristics include result orientation, continuous learning, resilience and professionalism. Considering the key role of managers in achieving the goals of universities, it is recommended to use the competency model extracted in this research for the appointment and promotion of administrators.

In recent decades, there has been significant emphasis on educational leadership and the performance of school principals in educational policies. The aim of this research is to explore and examine upper-level documents and conducted studies in order to clarify the current state of educational leadership and the transition towards it.

The current research is practical in terms of purpose and employs qualitative data collection and documentary analysis. It utilizes an inference-based approach through conceptual analysis and re-conceptualization. This method is a type of systematic review in which the researchers use it as a tool for categorizing a set of features related to a phenomenon and explaining them, instead of relying on a set of statistical rules. The study population consists of all relevant domestic research on educational leadership and upper-level documents of the educational system in the Islamic Republic of Iran, which were selected using purposive sampling of research and relevant documents.

The findings of the domestic research related to the topic of educational leadership at the school level indicate the identification of 29 features, which were categorized into four dimensions: "organizational management and improvement," "individual progress and educational development," "leadership patterns and models," and "leadership description."

Based on the analysis of the upper-level documents, it can be stated that except for the Fundamental Transformation Document (2011), in other documents, the topic of educational leadership has been implicitly and indirectly addressed under themes such as "school-centered management," "participatory management," "school-centeredness," "curriculum guidance," "facilitation," and "guidance."

This study aimed to investigate the impact of performance fatigue on visual perception, concentration, and reaction time among professional female volleyball players.

Methods and Materials:

The study population consisted of all professional female volleyball players in Qazvin province, with a purposive sampling method employed. A total of 24 eligible volleyballplayers were voluntarily selected and randomly divided into experimental and control groups.

Childhood stands out as a pivotal phase in motor development, making it essential to explore interventions that promote motor skills in children with autism spectrum disorder (ASD).
Objectives. This study investigated the impact of school-based games on motor skill development in children with ASD.

The study included 80 elementary school students, aged 11-12, from which 20 were randomly assigned to either an experimental group (n=10) or a control group (n=10). Employing a pretest-posttest design, the 8-week intervention consisted of 50-60 minute school-based game sessions, twice weekly. Assessment tools encompassed the Childhood Autism Test, the Oseretsky Motor Proficiency Test, and a researcher-designed School Games Checklist.

Results revealed significant between-group differences favoring the experimental group (P<0.05) in post-test scores on both gross motor skills (running speed and agility, balance, bilateral coordination, strength) and fine motor skills (reaction time, visual motor control, upper limb speed, and dexterity).

The games-based program effectively enhanced motor skills in children with ASD, underlining the importance of tailored movement and sports programs to support their physical, cognitive, and social development.

 Sarcopenia, the age-related loss of muscle mass and function, is a significant concern in geriatric medicine. Avicenna, a prominent figure in Persian medicine, emphasized healthy living and provided detailed instructions for the elderly.

 This review aims to evaluate the potential effectiveness of Avicenna's recommendations in preserving and improving motor control in the elderly population.

 A systematic search was conducted in electronic databases using relevant keywords to identify studies discussing Avicenna's recommendations for individuals over 65 years old. Avicenna suggested maintaining instinctive heat and essential body moisture through a balanced diet, including fresh fruits, vegetables, lean proteins, and whole grains. He also emphasized the importance of physical activity, moderate massage, and herbal remedies.

 Comparing Avicenna's recommendations with current research on age-related sarcopenia reveals significant overlap. Studies support Avicenna's emphasis on milk and meat consumption for muscle health. Avicenna's recommendations for physical activity align with current exercise guidelines for older adults.

 Incorporating Avicenna's recommendations into geriatric medicine may lead to improved outcomes for elderly individuals at risk of sarcopenia and motor control issues. Further research is warranted to explore the mechanisms underlying Avicenna's recommendations and their impact on sarcopenia prevention and management, as well as motor control improvement.

It was concluded that intermittent exercise and quercetin supplementation would increase the levels of Muc5Ac and Muc4 proteins in the large intestine of mice with colon cancer.

The COVID-19 pandemic has resulted in global home confinement and quarantine, leading to the vaccination of societies worldwide. However, some elite athletes have negative views toward vaccination. This study aimed to compare the lifestyle of vaccinated versus unvaccinated international elite athletes during the COVID-19 pandemic. From March to October 2021, an online survey was conducted, including socio-individual information of athletes, the International Physical Activity Questionnaire (IPAQ), the Rapid Eating Assessment for Participants (REAP-S), and the Petersburg Sleep Quality Questionnaire (PSQI). A total of 581 elite athletes from 4 continents (Europe, Asia, Africa, and America) and different countries, aged 18-35 years, were voluntarily recruited. Data analysis was performed using U-Mann-Whitney and Wilcoxon signed-rank tests, with the level of significance set at alpha P<0.05. The results indicated that there was a significant difference between the level of physical activity and eating behavior of vaccinated versus unvaccinated elite athletes (P<0.001). However, no significant difference was found between the quality of sleep among vaccinated and unvaccinated elite athletes (P=0.270). It was shown that, despite the unvaccinated status of some elite athletes (49.9%), their physical activity levels were higher than those of vaccinated elite athletes during the COVID-19 pandemic. Additionally, the eating behavior of vaccinated elite athletes was better than that of unvaccinated elite athletes during the COVID-19 pandemic, but there was no significant difference in the quality of sleep between the groups.

This research aimed to study the components of entrepreneurial attitude development in secondary high school students. The study was applicable in terms of purpose, quality-quantitative in terms of approach, and descriptive in terms of data collection. In the quality section, the studied population was the experts, planners and teachers of entrepreneurship, and they were selected by snowball sampling. The sampling process continued until data saturation was achieved. Data was collected through semi-structured interview and was analyzed using a three-step coding process of open, central and selective. In the quantitative section, the population was teachers of entrepreneurship in high schools in the regions of 1, 4, 5, 6 and 18 in Tehran in 2021. 250 teachers of entrepreneurship were selected based on voluntarily sampling and they completed the researcher’s questionnaire. The data were analyzed by confirmatory factor analysis and Amos24. The results showed that the components of the development of the entrepreneurial attitude of high school students have a central phenomenon of developing cognitive, personality and entrepreneurial skills and seven categories of problem solving skill, positive attitude of teacher and student to entrepreneurship, imagination, inner motivation, entrepreneurial personality traits, career perspective of students and applied education of entrepreneurship. The results of confirmatory factor analysis showed that these categories can explain the cognitive, personality and entrepreneurial skills of students. Therefore, in order to develop the entrepreneurial attitude in high school students, it is necessary to pay attention to the categories related to cognitive, personality and entrepreneurial skills. In order to realize the development of students' entrepreneurial attitude, it is suggested that teachers strengthen and improve these categories in the process of teaching and learning.

The restrictions caused by the coronavirus resulted in physiological and psychological problems for all ages in the world. This study aimed to investigate the effect of four weeks of aerobic exercise and caffeine supplementation on body composition and psychomotor performance of obese students who have recovered from COVID-19.

The current research was a quasi-experimental design with a two-step pre-test-post-test measurement. 40 obese students recovered from COVID-19 from Imam Khomeini International University of Qazvin Province eligible to participate in the research with a mean age of 22.57±1.45 years, weight of 90.74±7.53 kg, height of 171.05±4.93 cm, and body mass index of 30.51±2.36 were randomly assigned into four groups of 10 people including 1. Exercise-Supplement, 2. Exercise-Placebo, 3. Exercise, and 4. Control. The interventions included four weeks of aerobic exercise and caffeine or placebo supplementation. To analyze the data, a dependent t-test was used to check the intra-group difference, and an ANOVA statistical test was used to check the inter-group difference.

The results of the dependent t-test showed that there was a significant difference in all variables (body composition, and psychomotor performance) in the pre-test and post-test in the Exercise-Supplement, Exercise-Placebo, and Exercise groups (p<0.05), but in the pre-test and post-test, there was no significant difference in the control group for all variables (P>0.05). Also, intergroup analysis with the ANOVA test showed that there is no significant difference between groups in weight (p=0.144), fat percentage (p=0.053), and body mass index (p=0.993). However, there was a significant difference in psychomotor performance (duration of correct choice, number of correct choices, number of correct withdrawals, static balance, and dynamic balance) (p<0.05).

According to the obtained results, both aerobic exercise and aerobic exercise with caffeine supplementation can help reduce weight, body fat percentage, and body mass index, and improve psychomotor performance in obese people who have recovered from COVID-19.
