Sports injuries among physical education students are prevalent and various factors, including management factors, affect them.

In this cross-sectional study, by using the systematic design of the data based theory required information was collected from 12 physical education teachers through targeted interviews. The interviews were then coded and a theoretical model of the research were developed. Finally, in order to evaluate the accuracy of theoretical model a questionnaire was designed and completed by 330 physical education students and the effect coefficients of different parts of the model were investigated by modeling structural equations in PLS software environment.

The results of the analysis of qualitative data obtained from the interview led to the presentation of the model of prevention of sports injuries of physical education students based on managerial factors with 13 categories and 38 concepts in the form of 6 dimensions including causal factors, the main phenomenon, strategy, background characteristics, intervening conditions and outcomes. General test of structural equation modeling was performed using the Goodness of Fit Test and was confirmed(GOF = 0.74). The statistical value of T for the effect of each ofcausal factors, background characteristics, intervening conditions was higher than (1.96), so their effect was confirmed.

Thus, by modifying the approach of student admission, educational programming and securing places along with teaching and informing, we will be able to significantly reduce the incidence of sports injuries in physical education students.

The prevalence of sports injuries among physical education students is very high and significant. Although sports injuries are inevitable, it is not something we can't do anything to manage injuries. Various factors, including factors that are rooted in management issues, affect the vulnerability of physical education students, in order to make the necessary decisions to prevent the occurrence of sports injuries, the researcher in the present study identified managerial factors and presented a paradigmatic model for the prevention of sports injuries in physical education students.

This is a cross-sectional study using a database systematic design. The research sample consisted of 12 professors (5 trainees and 7 masters of management) who were selected from all professors of pathology and sport management in the country based on the logic of sampling phenomenological research in a purposeful and saturated manner. Semi-structured interviews were used to collect data. The data collected during the interview process were analyzed by an open, axial, and selective coding process.

The results of the qualitative data analysis of the interviews lead to the presentation of a model of prevention of sports injuries in physical education students based on managerial factors with 13 categories and 38 concepts in 6 dimensions including causal (3 categories), main phenomenon (prevention). Of the physical trauma of physical education students were: strategy (5 categories), contextual characteristics (1 category), confounding conditions (1 category), and outcome (3 categories).

Based on the paradigm model, it can be concluded that by modifying the approach in student admission, educational planning and securing places along with education and awareness, teachers, and students will be able to significantly reduce the incidence of sports injury in physical education students. Therefore, it is necessary to design model-based policies of the Ministry of Science in the physical education sector of universities to reduce the vulnerability of physical education students

Generally, fostering an active lifestyle and participation in sports activities are recommended, i.e., because of their impact on individuals’ health. However, participating in sports also presents the participant with risks and injuries. In other words, injury during physical activity is an inseparable problem in sports, and if acute, could cause an inability to move (or rarely, permanent organ failure). Moreover, it is associated with threatened biopsychological health status, decreased quality of life, increased medical costs, the fear of injury, decreased motivation, and absence from work and activity for the athletes. Research has suggested that sports injuries are more prevalent in physical education students than in other athletes. Any injury prevention planning firstly requires the identification of causes and factors of injury; thus, this study investigated the causes of physical injury in physical education students from the viewpoint of physical education professors.

This study followed the framework of the qualitative approach and the phenomenological method. Semi–structured interviews were used to collect the required data. The study population consisted of all professors of Pathology and Sports Management at universities with experience of teaching practical courses to physical education students. The study sample consisted of 12 professors who were selected based on the logic of the phenomenological research sampling approach in a purposive and saturated manner. Interviews with the professors were conducted in one month. In addition, we attempted to increase the validity of the findings using methods such as dedicating adequate time to data collection, consulting with two individuals familiar with the phenomenological research, and examining the negative and contradictory cases or the alternate descriptions. Subsequently, to validate the subsidiary and principal components, interviewerschr('39') perceptions were validated during the interviews to reflect the depth of meaning expressed by the participants. The data collected during the interview process were recorded and coded using MAXQDA 12 software. Besides, the obtained data were analyzed through open, axial, and selective coding process as well as in terms of content and theoretical basis.

Nineteen categories were extracted from the data provided by the interviewees involved in causing sports injuries in physical education students. These subcategories fell into 5 general categories, as follows: individual problems due to inadequate student admission process (low fitness level, musculoskeletal problems, the lack of motivation & interest), safety problems due to lack of control over the environmental factors (unsafe places, poor & inadequate educational tools, educational environment inappropriate with curriculum content), inappropriate physical education regulations and structures (inappropriate educational goals & approaches, inappropriate educational content, inadequate educational rules, inadequate classroom rules, inappropriate curriculum, inappropriate evaluation in case of content & training), the lack of knowledge and expertise (the lack of knowledge of traumatic factors & preventive methods from professors, their lack of expertise in the discipline, their deficiencies in the principles of performing exercises, unawareness of traumatic & preventive factors by students), and economic problems (using inadequate low quality tools & equipment, failure to complete injury treatment due to financial problems, & imbalanced nutrition).

The present study results revealed that various factors are involved in the vulnerability of physical education students. Such characteristics include individual problems, inadequate educational facilities, inadequate curriculum planning, inadequate content of practical units and inappropriate targeting in teaching and testing, poor knowledge and expertise of faculty and students regarding injury and prevention and, financial problems that reinforce such vulnerabilities. Furthermore, most of the related problems could be prevented through management strategies as well as modifying university admissions procedures, securing sports facilities and equipment, curriculum content and scheduling amendment, holding remedial courses in managing traumatic factors and to prevent and create financial support for students; these factors could reduce the odds of injuries in this population.

The purpose of this study was to identify the  success factors and measuring the effectiveness of e-learning among physical education students at Shahid Chamran University. This research was a practical study and it was done in descriptive method. The population was 342 students of physical education field at Shahid Chamran University of Ahvaz. Approximately, 160 subjects were selected using Morgan Table.  In this study, four effective factors in the implementation of e-learning including the quality of services and units, quality of information, interacting in online environment and the quality of system and infrastructure were evaluated and prioritized by a researcher-made questionnaire. Then, validity of the questionnaire was approved by experts as well as the  reliability of the questionnaire was estimated 0.82 using Cronbach's alpha coefficient. Validity of the hypotheses was tested by Student t-test and Topsis. According to Student t-test results, all four elements including quality of services and units, quality of information, interacting in online environment and quality of systems and infrastructure were considered effective factors on the success of e-learning at students. Moreover, based on the results of Topsis test, the most important factor was the quality of infrastructures, although interacting in online environment was the least one.

Ankle joint is known as one of the most vulnerable joints of the body. The aim of the present study was to compare the impacts and sustainabilities of NASM and combined excersices (neuromuscular and core stability) on the functional charactristics and balance of individuals with unilateral chronic ankle injury. A total of 36 male athlete students suffering from chronic ankle instability voluntarily participated in the present study and were randomly divided into three groups of 12: NASM excersices, combined training, and the control group. All the participants’ performance characteristics and dynamic balance were evaluated prior to, after, and four weeks after the exercises. To evaluate the functional characteristics, we used Side-to-Side Hop Test, Figure-eight Hop Test, Triple Hop Test, and questionnaires measuring the ability of the foot and ankle in sports and daily activities and to evaluate the dynamic balance, the balance test Y was used. Then, the NASM and combined groups performed the relevant exercises. The results showed that both NASM and compound exercises caused improvement in the dependent variables. Also, NASM exercises had lasting impacts four weeks after the exercise protocol in indicators of figure-eight hop test and the ability of ankle and foot test. Also, combination exercise had lasting effects observed in side-to-side hop test, figure-eight hop test, and the ability of ankle and foot scale. The results also showed that compound exercises, as compared with NASM exercises, were more effective as observed in the ability of the ankle and foot test. Doing eight weeks of combined training (neuromuscular and core stability) was observed to be significantly more effective, compared with NASM training, in the performance and postural control in patients with chronic ankle instability.

Hookah smoking is increasing worldwide. It is estimated the worldwide prevalence of daily hookah smoking is 100 million with shocking rising popularity among the youth. The aim of this study was to assess hookah prevalence in physical education students of Islamic Azad University, Ardabil branch within five recent years. This is a descriptive-analytic study, in physical education students of Islamic Azad University. Data collection was done in April, May and June 2009 and 2014, by means of self-administered two-page questionnaire. Almost half of students randomly participated in this study (162 of all 321students at 2009 and 235 of 467 students at 2014). Hookah prevalence significantly increased within five recent years (P<0.05). The main reason for hookah use was filling free time in both genders. Majority of male students used hookah at café whereas most female students used hookah at their own home. Passive use of hookah has been significantly increased among both genders (P<0.05). Unfortunately, in spite of propaganda about the side effects of hookah use, its use among physical education students has been increased since 2009, required scientific assessment. It seems enhancement of the number of café as well as rising hookah devices at homes is the main reason of significant increase of hookah use among students.

The cigarette and water pipe smoking is a public health problem. Many studies have been performed on prevalence of cigarette and water pipe smoking and its related factors. But in few studies the frequency and causes of tendency to cigarette and water pipe smoking among physical education students have been discussed. The purpose of this study was to evaluate the frequency and causes of tendency to cigarette and water pipe smoking in male and female physical education students in University of Kurdistan.
This descriptive and cross-sectional study was done on physical education students of the University of Kurdistan (128 male and 160 female) by standard questionnaire of PDUQ (Prevalence of Drug Use Questionnaire) using stratified random sampling method in 2013-2014 academic year. Data analysis was done by descriptive and inferential statistics including Kolmogorov–Smirnov and T tests at significance level of p Results showed that the respective rates of cigarette and water pipe consumption were 25 and 17.2 % for male and 11.25 and 7.5% for female students. In addition cigarette and water pipe smoking rates were significantly higher in male than female students (p The most important causes of proneness to cigarette and water pipe smoking in male and female students were identified as sincerely relationships with friends who were smoker and recreation and fun, respectively. Therefore, implementing educational programs and scientific field visits at university level seems necessary in order to prevent cigarette and water pipe smoking.

The aim of current study was the comparison of Bone Mineral Density (BMD) and Bone Mineral Content (BMC) of femur in physical educating and non-physical education students at universities of Bojnurd. Methods and materials: Fifteen physical educating (age: 22/33 ± 2/22 years) and Fifteen non-physical education students (age: 23/40 ± 1/29 years) from the different Bojnurd Universities participated in this study. Subjects were randomly selected in each group. BMD and BMC of femur measured using a Dual- Energy X-ray Absorptiometry (DEXA) system. SPSS software used to analyze data. Independent T test used to compare BMD and BMC between two groups. The significant level set at p≤ 0.05 for all statistical procedures. Data were normalized using kolmoghrov and Smirnoff test. The result of the current study showed that BMD and BMC, T- Score and Z- Score at different locations of the femur in physical education students were higher than non-physical education students. However this difference was not statistically significant. It seems that the practical courses for physical education student were not intensity enough to increase BMD and BMC in bone.
