The present study aimed to investigate the effect of cognitive-motor exercises on pain, range of motion, and quality of life in elderly female patients with knee arthritis. In this quasi-experimental study, 30 elderly female patients referred to the physical medicine ward of Tabriz International Hospital were selected via a convenience sampling method and randomly divided into experimental (n = 16) and control (n = 14) groups. Patients in the experimental group performed cognitive-motor exercises for eight weeks, three sessions per week, and each session for 45-60 minutes. Range of motion of the knee joint were used to measure pain and quality of life via electro goniometer and the KOOS questionnaire. The collected data were analyzed using combined analysis of variance test at the significance level of 0.05 in SPSS18 software. The research results showed that after cognitive-motor exercises, the amount of pain (P = 0.001), range of motion (P = 0.001), and quality of life (P = 0.001) improved significantly. As the findings indicated, it seems that cognitive-motor exercises can be used as a useful method for the rehabilitation of elderly women with knee osteoarthritis.

It has been shown in various researches that the focus of attention and quiet eye duration (QED) are effective variables on the performance of targeting tasks. However, the impact of these variables on motor skills in children needs more research; Therefore, the purpose of this study was to investigate the effect of different attentional focus instruction on QED and accuracy of children's darts throwing. Participants such as twelve right handed children (age: M=8.83, SD=0.79) without dart throwing experience participated in the study; while their eyes movements were recorded by an eye tracker system, participants performed 18 dart throws (6 blocks of 3 trials) under three different attentional conditions: 1) an external focus, 2) an internal focus, and 3) control conditions. The result showed that effect of focus of attention was significant neither for accuracy nor for QED. Therefore, in order to be aware of the optimal focus of children, more research is needed in various motor tasks.

This paper attempts to link social constructivism with future research by focusing on which, and to present a short-range theory in constructing the possible future of Iranian educational sport in this process, using the constructivist approach of the basic theory. The growth of educational sports is beginning of the development of sports. The data of this qualitative research had an exploratory-fundamental nature, and was collected through purposive sampling using snowball technique and based on in-depth semi-structured interviews with 22 experts in the field of educational sports. Accurate interpretive understanding and initial, focused, pivotal and theoretical coding showed that educational sport can achieve its desired future and set a vision for which, based on the requirements of future shaping, overcoming the past weight, present pressure and in line with future traction and choosing proactive behavior in the face of the future. Also, for participation in the student and university sports, two construction strategies were presented separately. As a result, a basic theory derived from the data, entitled "The planned future of Iranian educational sports" was explained.

The performance of sports clubs is considered due to the role of sports in community health; in this regard, the present study investigates the effect of coopetition on the performance of private sports clubs in the northern provinces of country regarding the mediating role of open innovation and the use of outside knowledge. This study is an applied and correlation type. The statistical population consisted of managers and members of the board directors of selected private football clubs in Guilan, Mazandaran, and Golestan that 245 of them were considered as a sample by non-randomized judgment sampling method. To collect the data, the standard questionnaires of coopetition of Bouncken & Fredrich (2012), the harmonized survey of open innovation (2012), the use of outside knowledge, and the performance of Wemmer et al. (2016) were used. Cronbach's alpha of the mentioned questionnaires is 0.816, 0.701, 0.797, and 0.803, respectively. Data analysis was performed using the structural equation modeling method of Smart PLS software. The results showed that the coopetition does not directly affect the clubs’ performance but affects it through mediating variables using outside knowledge and open innovation. It was also found that open innovation explains the highest percentage of changes in clubs’ performance. Therefore, cooperation and competition climate with using outside knowledge and open innovation can be such that the clubs’ performance is improved.

The purpose of this study was to determine the effect of dominant and non-dominant mental practice on Badminton's backhand short service. A total of 20 girls aged 12-14 years old from the city of Goldasht were selected and purposefully selected and randomly divided into two groups. Both training groups trained in 30 sessions, in which 50 performance were made to visualize the skill of the service mentally. In order to compare the two groups, the mixed ANOVA and Bonferron's post hoc test were used.  Comparing the between-group, the results showed that mental practice with dominant hands was not significant in dynamic environment and interactive exercise, but subjective exercise was significantly (P <0.05). No significant results were obtained in the within group comparison, but given the low effectiveness, it seems that the difference between the two groups is very close to meaning. Research findings suggest that coaches and teachers of interactive practice can benefit from less-than-lateral mental practice to improve the performance of their athletes in training sessions.

The purpose of this investigation was to examine the differences between novice and skilled baseball players to anticipate the type of ball being pitched and to specify the players’ dependence on distributed or local kinematic spatial cues. Male baseball players (N= 15; Mage: 27.73 ± 6.28 years; baseball experience: 7.90 ± 5.69 years) and novices (N= 15; Mage: 23.10 ± 5.68 years; no playing experience in baseball) were asked to anticipate the type of pitch (i.e., fastball vs. curveball) using a spatial occlusion paradigm. Both groups viewed recorded video simulations of spatially manipulated pitches in which nine specific parts of the pitcher’s body or the ball were either omitted or showed separately. The data was analyzed by a 2 (Skill level) × 9 (Display Condition) mixed-design analysis of variance. The results revealed that skilled baseball players outperformed novices in the occlusion conditions. Furthermore, the results revealed that skilled baseball players used throwing arm and ball as well as upper body kinematic cues for their correct anticipations. The results are in line with previous findings on perceptual-cognitive expertise and decision-making in interactive sports and indicate skilled baseball players are able to obtain information distributed globally within the pitcher's body, rather than reliance on specific isolated or local kinematic cues.

The purpose of this study was to design a model of business strategies for marketing sports products on social networks. The statistical sample of this study consisted of 20 experts (university faculty members, employment and entrepreneurship consultants, and sports market consultants and sports business managers). Sampling was purposeful and snowballs and continued until the interviews reached the stage of theoretical saturation. Data were collected through in-depth and semi-structured interviews. The validity of the study was confirmed based on the criteria of "acceptability", "transferability" and "verifiability". Also, 85% reliability was reported. According to the obtained results, it can be said that in order to provide an implementation mechanism, 1) innovation strategy, 2) customer relationship strategy, 3) infrastructure strategy, 4) development strategy, 5) service strategy, 6) Expert manpower strategy, 7) Promotion strategy, 8) Pricing strategy and 9) Product strategy to be considered. Marketing strategies have an impact on the performance of sports businesses, meaning that sports businesses on social networks can reach a good position in a competitive environment when they have a good marketing strategy. Therefore, it is necessary for sports business managers in social networks to pay special attention to marketing strategies in order to develop their performance.

Nowadays, technology is becoming one of the most important factors that contribute to the Internationalization of recreational sports industry.This study was done to design a model to develop recreational sports by new technologies in Iran. This study was carried out with mixed Methods.In the qualitative part, semi-structured interviews were conducted with 13 participants through purposive and standard sampling methods. The content analysis method was used to analyze the data and in the same section, a questionnaire was prepared based on the identified themes from the qualitative part, which included the available dimensions and components. Questionnaires were distributed among 406 samples after confirmation of validity and reliability. Descriptive statistics and confirmatory factor analysis were used for analyze the data. The findings of this study showed that the main themes of the model of development of recreational sports through new technologies are divided into four parts: propulsion and stimuli, challenges of using new technologies, opportunities to use new technologies and consequences of using new technologies in the development of recreational sports. Presently, increasing human-computer equipment interaction is facilitating new ways of using technology in sports environments, and in the future, technology will bring structural changes in all sectors of sports, especially recreational activities.

Nonlinear methods in physical education is a new idea that covers all the disadvantages of the traditional method and is effective for learning and implementation based on the results of studies compared to the linear method. However, it is not clear how much this method is used by trainers in Iran. This study sought to determine what kind of method (linear / non-linear) instructors use for training. Therefore, 15 expert trainers were selected by available method and interviewed by semi-structured method. The study and determination of linear or non-linear methods was based on the differences between linear and non-linear methods and the results showed based on the interview of trainers and taking into account the target categories, repetition, pattern, description, variability, feedback and instructions. The educators studied in this study use the linear method in education. The results of this study show that the university environment and practice in the field of education are separate and emphasizes that specialists in nonlinear methods should raise the awareness of sports coaches by holding training workshops and increasing knowledge. Also, the use of physical education graduates in the field of coaching and as teachers of federations may be helpful in this regard.

Understanding how physical-activity of Iranian-girls aged 7-12 years in the current situation and designing a model for it is a requirement of strategic-thinking and it can help relevant managers make important decisions. Therefore the purpose of this study was to design a conceptual model of physical-activity for Iranian-girls aged 7-12 years. The research method was Grounded theory, systematic approach. The sampling method was theoretical sampling and in order to achieve theoretical saturation, semi-structured interviews were conducted with 6 fathers, 17 mothers and 17 girls while studying literature. Findings show that there are 14 main categories related to the physical-activity of Iranian-girls aged 7-12 years. The main actor in the designed model is the mothers who consider the conditions and plays the role of the main guider of the girl in consultation with her husband and daughter and the trainer. The findings also showed sovereignty institutions, the Ministry of Education, and schools; unexpectedly; do not have a favorable effect on the physical-activity of Iranian-girls aged 7-12 years. Thus; meaningful activation and constructive interaction between mothers, related organizations and institutions; especially schools; and the optimal use of the existing sports facilities in the country can significantly increase physical-activity among girls aged 7-12.

In this study, some predictions and consequences of football fans' engagement have been examined. The present research is applied in terms of purpose and in terms of how to collect descriptive information of correlation type. To collect the required data, Persepolis football team fans (n = 220) were considered as a statistical sample and completed the electronic questionnaires voluntarily. To collect data from six questionnaires; Team Quality Questionnaire Zhang et al. (1997), Communication Quality Questionnaire Nyadzayo et al. (2015), Emotional Satisfaction Questionnaire Reynolds & Beatty (1999), Perceived Value Questionnaire Daniel Sweeney (2008), Engagement Questionnaire Researcher-made, Behavioral Questionnaire Kim (2008) has been used. The results of structural equation modeling showed that team quality affects emotional satisfaction and engagement of fans, but relationship quality only affects engagement. The relationship between emotional satisfaction and fan engagement as well as the relationship between engagement and behavioral intentions was positive and significant. The role of positive mediation of emotional satisfaction on the relationship between team quality and fan engagement was confirmed. Also, Perceived value moderated the causal relationship between relationship quality and emotional satisfaction. According to the results, it is suggested that the clubs, by improving the quality of their team and relationship with the fans, create a permanent engagement for them so that they can increase their intention to re-presence and word of mouth spread.
