Purpose: Muscle flexibility is a component of physical fitness. Using traditional tools in muscle length evaluation tests creates challenges. Therefore, the use of smartphones and health-related software as an alternative method has become widespread. This study aimed to investigate smartphones' intra- and inter-rater reliability and validity for measuring hamstring muscle length. Method: In a blinded study design, two researchers measured hamstring flexibility through four types of tests on each of the 22 asymptomatic participants with a total of 44 lower limbs. The measurements were compared between the traditional goniometer method and the practical smartphone application method. The intraclass correlation coefficient (ICC) was used to evaluate the reliability of each smartphone measurement, and Bland-Altman analysis was used to check the measurement errors. The validity of the two methods was also investigated. Results: Intra- and inter-rater reliability (ICC≥0.8) were good to almost perfect. In intra-rater reliability, PSLR angle showed consistent imprecision; other tests were free of systematic error and measurement error. The inter-rater reliability revealed a constant error in the right leg's PKE angle. A good to excellent correlation (r = 0.817–0.699) was observed in all the measured values, indicating the two methods' validity. Conclusion: These findings support from intra- and inter-rater reliability and validity of both instruments when measuring hamstring muscle length.

Background: Along with the outbreak of coronavirus and quarantine practices in many countries, physical activities have certainly been severely restricted. The purpose of this review was to investigate the role of technology in maintaining and improving physical health. Method: For this systematic review study, the research method in this study included searching on PubMed and Google Scholar databases. Articles written in English and Persian in peer reviewed journals that examining the effect of electronic games and virtual reality on physical fitness were selected for analysis. Then, the eligible studies classifieds based on the study population ages. Results: Of 12563 studies found, 14 studies were eligible to enter the study. Research has shown that the use of technology significantly affect gait, balance, strength, flexibility, and mental functioning of the elderly, as well as balance, strength, endurance, and cognitive abilities in adults and children's physical endurance. Conclusions: According to studies under review, the use of technology has a significant effect on improving and maintaining the physical and mental fitness of people in different ages. So, we can suggest using exergame and virtual reality exercises as a possible intervention to promote and maintain physical and mental fitness in quarantine.

Purpose: The purpose of this review was to investigate the effects of exercise interventions on physical and psychological health in Iranian war veterans. Method: The search strategy for this review consisted of an electronic database search of full text papers in Google Scholar and SID.ir databases.10 studies met the eligibility criteria, all of them interventional in nature. The studies were analyzed separately according to the specific areas of study. Results: The studies demonstrate that exercise interventions have a significant impact on physical health, psychological health, and quality of life in Iranian war veterans. However, inconsistencies were generally apparent between some of the results. Conclusions: Exercise interventions have positive effects on physical and psychological health in Iranian war veterans. More investigation is needed to identify optimal exercise protocols for different groups of veterans.
