The quantitative studies have shown that cyclists around the world have different attitudes and perceptions of safety needs. Therefore, in this study, we want to examine the experiences of injured cyclists about safety needs in a qualitative study.

 The present study was a qualitative study witha  content analysis method. The study population consisted of male or female cyclists over 18 years of age who were injured in a crash or fall while cycling and one or more of their limbs were injured and hospitalized in Poursina Medical Center. Excel details of these clients were obtained from the registration system ofthe  Guilan Road Trauma Research Center. People with various characteristics in terms of age, sex, education, marriage, sex, occupation, length of hospital stay, etc. were included in the study. The number of participants was twenty. Interviews were conducted by medical students with the cooperation and supervision of supervisors.

 Safety factors from the experiences of injured cyclists included nine categories, which were: orderly cycling, holding training courses, supervising cycling, observing the principles of cycling, being equipped with safety equipment, having the right to an exclusive route , Reviewing exclusive routes, creating a sense of security and creating peace in women cyclists.

 Authorities should try to make the factors that were safe in the experiences of these injured as much as possible to give these users a sense of calm and security, thereby encouraging others to ride a bicycle as a clean vehicle for the environment.

 The aim of this study was to investigate the effect of a corrective exercise course on myofascial release on pain, posture, disability index, and quality of life in people with video display syndrome.

 This study was semi-experimental and applied with a pre-test-post-test design with a control group. 45 middle-aged men (40-45 years old) suffering from video screen syndrome based on the study inclusion criteria were selected as a statistical sample and randomly divided into three experimental groups 1 (15 people), experimental 2 (15 people), and control (15 people) were separated. Before and after 6 weeks of training intervention that took place for 45 minutes and 3 sessions per week; In order to measure the amount of pain and disability, forward head posture, kyphosis, and quality of life, respectively, using a visual analog scale (VAS), neck disability index questionnaire (NDI), neck pain and disability scale questionnaire (NPDS), photography method and SF-36 questionnaire were used.

 The results showed that the amount of pain (F=31.40 and P=0.001), forward head posture (F=29.75 and P=0.01), kyphosis (F=29.75 and P=0.01) P), disability index (F=30.79 and P=0.01) and quality of life (F=51.83 and P=0.01) of the intervention group improved significantly in the post-test compared to the pre-test (P <0.05). Also, a significant difference was observed in all the variables between the experimental 1 and experimental 2 groups in the post-test (P<0.05). So that corrective exercises with myofascial release had a more significant effect on the improvement of research variables.

 The findings showed a reduction in pain, improved posture, disability index, and quality of life in the group of corrective exercises with myofascial release compared to the group of corrective exercises without myofascial release; Therefore, in order to reduce musculoskeletal injuries and increase efficiency and productivity, it is recommended to use corrective exercises with a myofascial release for men with video monitor syndrome.

 Given the high prevalence of functional ankle instability, its primary and secondary costs, and most importantly, the personal suffering of injured people, proposing an effective rehabilitation program is essential. Therefore, the aim of the present study was to review the effectiveness of VR-based interventions in the rehabilitation of patients with ankle instability.

 Articles were searched on the SportDiscus, PubMed, Web of Science, Medline, Scopus, and EMBASE databases without any time limit from the inception to Jun 2021. Selective keywords were virtual reality, ankle instability, and clinical outcomes such as balance, postural control, range of motion, pain, strength, function, and gait function. The Pedro scale was used to evaluate the methodological quality of the selected articles. The reporting of this systematic review was guided according to the standards of the PRISMA statement.

 After removing duplicate and irrelevant articles, the full text of 10 articles was obtained from the databases, and the required information was extracted. The results of studies used within group analysis indicated that VR-based interventions had a significant effect on balance, postural control, and motor and self-report function of people with functional ankle instability. However, there is no significant difference between the effectiveness of VR-based interventions and traditional physiotherapy in terms of effects on balance, postural control, and self-report performance in people with functional ankle instability.

 Although there is no evidence that virtual reality-based interventions are superior to traditional rehabilitation, the results of the present study suggest that virtual reality-based interventions are at least as effective as traditional exercises for people with ankle instability. However, due to the methodological weaknesses of current studies, more detailed studies are needed to evaluate the effectiveness of VR-based interventions for patients with ankle instability.

 With regard to earthquakes and their sudden occurrence, special programs should be designed and implemented for people in order to encounter a probable disaster as well as to show appropriate and on-time reactions against it. In this paper, the main objective is to reduce the casualties and damages of earthquakes with the cooperation of people and identify the various methods for encouraging the local communities to cooperate in risk reduction programs and increasing resilience.

 The study is mixed-method research. The information is gathered through questionnaires, interviews, and checklists from the 22 sections of Tehran. 25 questions have been prepared and asked from 240 available participants through the internet (136 women and 104 men). For the qualitative section, 22 in-depth interviews were undertaken with experts in the field of disaster management employing content analysis. For the quantitative analysis, descriptive statistics were used through Spss software version 22.

 The obtained findings reveal the necessity of initiating and improving issues such as paying attention to the effective role of community cooperation in disaster management stages, organizing community-based programs in neighborhoods, initiating "bottom-up" communication channels, reinforcing the incentive mechanisms, strengthening the NGO's activities and mobilization of neighborhood services, as well as using new technology in communication, mobile applications, and media in order to stimulate the incentives of various groups of people for prioritizing issues related to earthquake risk reduction.

 The results show the importance of identifying various methods of encouraging local people in risk reduction programs and increasing safety, formation of community-based disaster management centers and active civil organizations at the national to local levels with the cooperation of public groups, addressing new ways for preparedness and awareness by performing continuous educational and awareness programs in places such as schools and cultural centers and in general, involving local communities to cooperate in risk reduction projects and increasing their resilience and safety.

 The difference in altitude due to the foot's arch between people with normal and flat feet affects gait parameters and may increase the risk of injury. Accordingly, this study aimed to compare the effect of exhaustive activity on dynamic balance (DB), joint mobility (JM), and joint proprioception (JP) in women with flat, hollow, and normal feet.

 In this study, 30 participants were given a written informed consent form, and selected based on inclusion and exclusion criteria and the doctor's confirmation that the exercises were safe, and divided into two experimental groups of flat, hollow feet and a control group (10 participants in each group) by simple random sampling. The variables of the DB test (Y test), JM (goniometer), and JP (AutoCAD software) of the subjects in the pre-test stage were measured. After that, the group performed flat and hollow feet in exhaustive activity during one session.

 The results showed that there was a significant difference between the pre-test and post-test of DB, JM, and JP of the subjects in the three groups. There is a significant difference between the mean difference of DB, JM, and JP of normal and hollow feet. But no significant difference was observed between the experimental groups' mean DB, JM, and JP.

 Based on the results of this study, coaches in sports teams are recommended to improve the fatigue threshold in the athletes by designing appropriate programs and thus prevent injuries to the fullest extent.

 Recent studies have shown that motorcycle accidents are the most deadly Road Traffic Accidents. Detection of accident hot spots plays an important role in preventing these incidents. Therefore, this study has been done with the aim of detecting the accident hot-spots of motorcycle accidents in Gonabad and Bajestan counties.

 The present study is a retrospective cross-sectional study. The research tool was a standard questionnaire designed by the ministry of health and medical education in Iran. Data and spatial characteristics of motorcycle accidents were extracted from these questionnaires. To perform spatial analysis, the layer of motorcycle accidents in Gonabad and Bajestan counties was drawn by ArcGIS version 10 software.

 In Gonabad and Bajestan counties in 2019, 732 motorcycle accidents were registered in Gonabad and Bajestan counties. 58% (N=430) of accidents occurred in the central part of Gonabad city. The highest density of accident hotspots in Gonabad city in the area of Imam Khomeini Square, Nasser Khosro Street, and Saadi Street at the intersection with Pasdaran Boulevard, Taleghani Boulevard, Jomee Bazar, and Shohada Street. Also, the highest number of accidents in Bajestan in Motahhari Boulevard, Shariati Boulevard, and Azadi Square are registered.

 The highest density of hot spots of motorcycle accidents has been recorded in the central part of Gonabad. Therefore, it seems necessary to take preventive measures by investigating the root causes of accidents in identified areas. In addition, the spatial analysis of the obtained maps can be useful in locating pre-hospital emergency bases and police stations.

 Considering the negative consequences that sports injuries can bring to the athlete, team, and healthcare system, strategies should be sought to prevent them from occurring. The present study aimed to investigate the relationship between the total quality of recovery and training load with sports injuries in adolescent soccer players.

 The present study is prospective. Our study sample consisted of 100 male soccer players with an age range of 16 to 21 years, who were selected in Sanandaj city after receiving the ethics code during 2018-2019. One hundred young soccer players aged 16 to 21 years old who participated in the study that was recruited from three clubs. The total quality of recovery scale was used to assess the soccer players' quality of recovery. Training intensity was also recorded immediately (approximately 30 minutes) after the competition or training session using the ratings of the perceived exertion scale. To calculate the total training load, the training time was multiplied by the ratings of perceived exertion per minute. Independent t-test, GEE, and ROC curve were used to analyze the data.

 The results of the study showed that there is a significant relationship between the total quality of recovery and training load with sports injuries in adolescent soccer players (P<0.05). The findings of the present study showed that for every unit decrease in the overall quality of recovery, the risk of sports injuries increases by 10%, and for every 100 units increase in the total training load, the risk of sports injuries increases by 3%.

 The results of the present study indicate the importance of frequent monitoring of the recovery process and training load to minimize the risk of injury to young soccer players.

 Many researchers have reported changes in movement patterns after injury. In this regard, the aim of this study was to compare the performance test of FMS in professional Wushu athletes with and without injury.

 In this cross-sectional and causal-comparative study, 120 Wushu players in the age range of 23 to 30 years were purposefully selected based on inclusion criteria. The evaluation of functional movement patterns was assessed by FMS functional test. Data were analyzed using SPSS software version 26 through descriptive statistics, the Chi-square test was used to compare the difference between the groups with and without injury, and univariate and multivariate logistic regression tests were used to compare the two groups.

 The results of this study showed that there was a significant difference between the performance test scores between the two groups. The non-injured group reported a higher overall score than those with a history of injury.

 It can be pointed out that injury can mainly lead to changes in movement patterns. Athletes with a history of previous injury may have faulty movement patterns; therefore, they may have problems when performing high-level sports activities.
