The present study is implemented to identify indicators and to provide an optimal evaluation method in recreational-sports pools. The present study is considered practical in purpose, and survey in collecting data. Firstly, by bibliometric research and five professional experts’ interviews, 91 indicators were identified for evaluating recreational-sports pools. Secondly, in terms of 4 components or perspectives in the Balanced Scorecard, 57 indicators were established (internal processes (10 indicators), customer (22 indicators), growth and learning (19 indicators), and financial (6 indicators)), from focal group’s output which was comprised of 4 prominent professors. The structure was confirmed based on 333 individuals’ opinions in the statistical population by employing factor analysis. In order to rate the pools studied, the gray clustering analysis method was applied followed by the structure of the balanced scorecard confirmed. Principally, 20 homogenous recreational-sports pools were investigated in 15 city regions and boundaries of provinces in Isfahan, Sepahan Shahr, and Baharestan. Based on data analysis and rating of each case study, Araman, Absar, Enghelab, Morvarid, and Golsar pools were ranked first to fifth, respectively. Furthermore, the main purpose of the present study based on calculated indicators is to propose a practical method to provide an accurate evaluation of sports pools. 

Purpose: Osteoporosis usually starts at a young age and progresses slowly over time. Therefore timely diagnosis of this disease plays an effective role in raising the level of health and public health in the society. The aim of this study was to investigate the relationship between some indicators of osteoporosis and bone mineral density of the pelvis in active elderly men. Methods: This study was semi-experimental. 25 active elderly men with the age range of 60 to 85 years were selected as available and with medical records. Anthropometric characteristics and serum indices of subjects were used as effective indices of osteoporosis. Pearson's correlation coefficient was used to find the relationship between bone mineral density of the pelvis and effector indices, data analysis was done using SPSS version 26 software. Results: The results of this research showed that in the active elderly men, there is a significant relationship between age (P=0.044), body mass index (BMI) (P=0.021), serum calcium (P=0.037) and phosphorus levels (P=0.046) and alkaline phosphatase (P=0.016), with bone mineral density (BMD) of the pelvis. No significant relationship was found between vitamin D with BMD of the pelvis (P=0.055). Conclusion: In general, the results show that there is a significant relationship between bone density and body mass index, calcium and serum alkaline phosphatase indices in active elderly men. Therefore, it is possible to use the serum levels of these indicators in predicting this disease, and exercise may also be one of the influencing factors, so the effect of exercise on other bone density indicators can be investigated.

Although the succession planning literature focuses more on managerial and staffing levels in organizations, it can also be used for players in clubs and sport teams. The purpose of the research was to identify and evaluate a model of player succession in Iranian football premier League. The research method was mixed (qualitative and quantitative). The statistical population of this research in the qualitative section includes 16 specialists and experts in football, and in the quantitative part of the research, all managers, athletes, coaches and football referees in the Premier League in 2020, and finally 286 subjects were studied through stratified random sampling in quantitative phase. Research hypotheses were examined using correlations and structural equations modelling . A total of 189 primary codes (concepts) were extracted in the coding process, which after validation, 33 primary codes (concepts) were compiled. In the model, causal conditions included binding or motivating factors as well as the process of replacing players. Underlying conditions involved networking to develop a player replacement program, interacting with other organizations, formulating binding strategies, and setting a budget to promote win-win thinking in the football club succession program in Iran.

Background: Diabetic peripheral neuropathy (DPN) reduces the senses, proprioception, reflexes, and strength in the lower extremities and leads to balance dysfunction. Aim : This study aimed to evaluate the effectiveness of interventions used by researchers and therapists to minimize balance dysfunction in people with DPN. Materials and Methods: This study is a comprehensive review of exercise interventions on the balance of patients with diabetic neuropathy by searching in the PubMed Elsevier, Springer, Science Direct, Google Scholar, and Scopus databases with the combined keywords “balance”, “diabetic peripheral neuropathy”, “training interventions”, “proprioception”, “risk of diabetic fall”, “peripheral neuropathy” and also in Persian databases of Jihad Daneshgahi Scientific Information Center, MedLib (Comprehensive Database of Medical Articles), IranMedex, Iran Institute of Information Science and Technology Research Institute (IRANDOC), Iranian Publications Database (MAGIRAN) and with keywords “fall risk”, “profundity” and “postural control in diabetic neuropathic patients” from 2010 to 2021. After collecting the search results, first the title and then the summary of the pieces were studied. If the articles met the inclusion and exclusion criteria, their results would be used in the review study and otherwise discarded. Results: Twenty-five studies published between 2010 and 2021 met the inclusion criteria. The results showed that training interventions were more effective than control conditions to improve the balance of patients with diabetic neuropathy. Also, the most training programs and rehabilitation protocols have a positive effect on the balance of patients with diabetic neuropathy. Conclusion: The studied exercise interventions are an effective tool to improve the balance of diabetic neuropathy patients. However, given the small number of studies and their limitations, the present findings of this study should be considered.
