This study was conducted to identify and to rank the factors affecting market retention in fitness centers.14 participants including the customers and managers of fitness centers participated in a semi-structured interview to collect the required data. Sixteen factors were extracted from the interviews and sixteen experts evaluate the relationships among these factors with pairwise comparisons.Based on Interpretive-Structural Modeling, the factors categorized in five levels, i.e. 1) customer relationship quality,customer experience quality, reputation, price, perceived value and satisfaction, 2) Overall servicequality, secondary services and ethical climate, 3) Training type and schedule, location and accessibility and social responsibility, 4) Interior design and equipment, 5) Manager communication and trainer’s competencies.   For the sake of customer retention, fitness centers are required to align their decisions with their customer requirements. Ranking the effective factors in this study can provide the fitness centers’ managers with a better understanding of the factors affecting customers’ decisions.

Background : Excessive repetitions of the landing and jumping task are a key risk factor for lower extremity injury (specially ACL) in female volleyball players. Aim: this study investigates the effect of Sports-Metrics Volleyball Training (SMVT) on landing technique in female volleyball players. Materials and Methods : The participants of this study were 25 female young volleyball players and randomly divided into training (TG, n=13) and control groups (CG, n=12). The TG performed SMVT for 18 sessions, and the CG performed their regular training. Landing error scoring system (LESS) test were used for assessing landing errors. SPSS (version 25) was used to analyze the statistical data ( P <0.05). Results : The results of the data analysis showed a significant improvement ( P =0.01) in LESS in TG (from 8.62 to 5.54), but no significant changes in CG the LESS ( P =0.62, from 8.00 to 8.23). Eighteen sessions SMVT reduced the landing error by 35.73% in the TG. Conclusion : Base on previous research the SMVT reduces lower extremity injuries and the results of this study showed that SMVT significant improvement the landing technique. Therefore, performing SMVT is recommended for female volleyball players because it is effective in both preventing injuries and improving landing technique.

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.
