One of the most important issues for the elderly is the issue of physical health and cognitive problems. The aim of this study was to compare the activity of dual resistance-cognitive task with different intensities on fatigue, balance and cognitive function of elderly women. The present study is an applied and quasi-experimental method with the presence of 20 elderly women aged 60 to 70 years, which was done as a one-session test and getting answers. Subjects performed exhausting tests of foot press with machine and shoulder press with dumbbell with combined cognitive load with two different intensities (70% 1RM with low cognitive load and 30% 1RM with high cognitive load) in two days with an interval of 48 hours and the results were recorded. Balance test, upper and lower torso muscle activity and Stroop test were measured. The results of fatigue time, cognitive test and balance were significantly different between the two intensities (p <0.05). But in relation to the middle spectrum of muscle frequency, no significant difference was observed between the two intensities (p> 0.05).  Using low-intensity, high-cognitive exercise is more effective in treating upper body fatigue, which puts more pressure, which may need further investigation to evaluate the long-term success of these programs.

 So far, there has been a lot of scattered research on various aspects of the benefits of physical activity for women in various disciplines, but there has been no coherent analysis and theorizing. Therefore, the aim of the present study was to identify, categorize and examine the types of benefits of physical activity for Iranian women at different stages of life and to theorize about the process and impact of experiencing the benefits of physical activity on primary motivations. The research method was Grounded Theory, systematic approach. Sampling was theoretical. Data analysis was performed through continuous "questioning" and "comparison". In-order-to achieve saturation while reviewing specialized texts, semi-structured interviews were conducted with 136 Iranian-women aged 7-78 who were regularly participate in physical-activity in addition to 17 mothers and 6 fathers. The findings of the present study show that the benefits of physical activity for Iranian women can be classified into six general categories: (1) "health development", (2) "motor development", (3) "socio-behavioral development", (4) "enrichment of leisure time", (5) "Beauty" and (6) "Prevention and Treatment". Findings also showed that experiencing the benefits of physical activity strongly influences the modulation of initial motivations and the formation of strong and lasting motivations. According to the research findings; Cultural-sports managers should include all the important benefits of physical activity experienced by women at different stages of life in the content of Iranian women's physical activity promotion programs and do not suffice to provide general and specialized intangible content.

Our understanding of the effectiveness of small-sided games compared to other training methods is limited. Therefore, the aim of this study was to compare the role of small side games (SSG) and traditional teaching method on individual and team creativity of 11-12 year old soccer players. To conduct this study, among all the 11-12-year-old children of Iraq who were enrolled in football classes, 30 learners were selected by the available method and were randomly divided into two groups of traditional and SSG education. At first, the pre-test was taken by the video analysis method, and then the participants practiced football skills on the 7x7 field for 16 weeks and 4 one-hour sessions every week. Finally, the post-test was evaluated according to the pre-test. The analysis of the film was done based on the opinion of two experts and according to the previously identified practices. The results were analyzed by descriptive method and 2x2 ANOVA analysis in SPSS 24. The results of the study in the descriptive part showed that appropriate actions, creative and original actions have grown more in the SSG group compared to the traditional group. In this regard, inappropriate actions have shown a further decrease. In the section of inferential tests, the results showed that the effect of the test and test*group is significant for appropriate actions and the effect of the test for total actions showed the same result. In this regard, small side games can be played by placing the player in a small environment, allowing the player to have more opportunities to perform and less time to make decisions, which leads to the improvement of creativity in team sports such as football.

The aim of the present study was to examine the effect of cyberspace dependence on the explicit and implicit motor sequence learning task. For this purpose, the number of 48 subjects aged 16 to 19, were selected as available and was divided in four groups (12 people) including cyberspace dependent - explicit motor learning, cyberspace dependent - implicit motor learning, normal - explicit motor learning and normal - implicit motor learning. Kimberly Young's internet addiction test was used to distinguish between normal and cyber-addicted people, and SRTT software was used to check participants' learning. The data were analyzed using the mixed analysis of variance test with repeated measures. The findings showed that cyberspace dependence had a significant effect on the explicit and implicit motor sequence learning task, so that there was a significant difference between the two groups of cyberspace dependent and normal peers in the explicit and implicit learning motor sequence task. Normal people performed better in both explicit and implicit conditions than cyberspace dependent participants. According to the findings, it is suggested to reduce the excessive use of virtual space in the students by creating energetic movement programs in schools.

The present study aims to investigate the variables of social networks in different positions in basketball. These variables were applied in two levels of analysis: micro (individual) and macro (global interaction of the team). 24 official Chemidoor Club competitions in the 2020 men's Iranian Premier League were selected by available sampling. This research analyzed the network properties of Degree, Betweenness, Closeness, Eigenvector, and Density centrality across teams and positions. The one-way ANOVA for the factor position in the micro-level found statistical differences between the game positions in the dependent variables of  Dc: (F(4,15)= 61/29, p= 0/000), Bc: (F(4,15)= 210/11, p= 0/000), Cc: (F(4,15)= 78/55, p= 0/000). However, no significant difference was observed in the Eig: (F (4, 15) = 1/58, p= 0/184). Results of post hoc test indices were significantly different between position 1 (point guard) and other positions.  Macro-level team density analysis showed a significant difference between performance results in successful and unsuccessful. The guard player role was observed as the situation that establishes the most interactions with teammates during the competition. Therefore, players with higher degrees were not the ones assisting the most shots. The other players with higher degrees were not the ones assisting the most shots. These results may be used as a tool for coaching to improve their teams’ strategies in concrete, measurable ways.

The literature on self-controlled motor learning includes efforts that compare a group of learners who have choices about some aspect of their practice environment with a group who are dependent on those choices. Therefore, several studies have shown that self-control practices have benefits. In the present study, using the self-control approach, the choice order during golf practices, the level of skill accuracy, autonomy, and self-efficacy were investigated. The present research is of a semi-experimental type and was carried out during the 24-hour follow-up period. Twenty-four beginner students were available and randomly placed in the experimental group (n=12) or yoked group (n=12). In the pre-test, the participants took the golf putting test. Then the yoked group used the practicum devices in the order of choice of the experimental group. On the first day, skill accuracy, autonomy, and self-efficacy were measured in the pre-test and acquisition, and then with the retention test. The results of the repeated Measurements analysis test showed that self-control has a significant effect on golf putting skill, autonomy, and self-efficacy. Therefore, a small choice such as the order of practice in the self-control approach can be effective on motor performance and learning, and the psychological components related to them.

The aim of the present study was to investigate the effect of inducing positive stereotypes on perceived competence, interest and motor learning in adolescent girls. Therefore, among all of the adolescent girls in Shiraz, 30 adolescent with the age range of 10-13 years were selected by convenience sampling. Participants performed 10 trials as a pre-test and afterward, they were randomly divided into two groups  . The acquisition phase consisted of 50 trials (5 blocks of 10 trials), and the task required participants to perform inside kicks at targets area attached to a wall and touching the ground. Twenty-four hours after the acquisition phase, participants attended retention test (with 10 trials) to check learning effects on them. The participants were asked to answer the questions related to perceived competence and interest before pre-test, after the acquisition phase, and before the retention test. To analyzing data, one way and Mix ANOVAs analysis and Independent T test were conducted using SPSS21 at significance level P≤0.05. The results showed that in the acquisition phase, all groups significantly increased their accuracy, though difference among groups was not significant. Also, the results showed that the induction of positive stereotypes led to higher perceived competence and motor learning in adolescent girls

The aim of this study was to comparison of the effectiveness of linear and non-linear pedagogy on locomotor motor skills Performance and movement motivation in children with developmental coordination disorder. The statistical population was all children with developmental coordination disorder in Urmia. The statistical sample consisted of 30 boys (age = 9.35 ± 1.37) who were selected from Urmia schools using the available method. MABC-2 test was used to diagnose developmental coordination disorder, TGMD- test was used to evaluate locomotor skills, and motor motivation test was used to evaluate movement motivation. To carry out this study, the participants practiced two 50-minute sessions of motor skills interventions in two linear methods (15 people) and task manipulation (15 people) for eight weeks. Variables were measured before and after the interventions. The results of covariance analysis showed that non-linear training compared to linear training significantly improved both in movement skills (p=0.04) and motor motivation (p=0.000) than the linear group. According to these results, non-linear methods considering the individual characteristics of each child are helpful for helping children with movement disorders. Considering the unique characteristics of each child helps to improve motor skills and to have enough motivation to continue the activity. Therefore, the use of non-linear methods is suggested for children with developmental coordination disorder.

Objective:The purpose of the study was to investigate the effect of gender stereotype induction on girls' agility performance in the presence of secondary cognitive task. Method: 14 students studying in a physical education technical and vocational school participated in the study. Participants performed the hexagonal agility task in four different research contexts with a 20-minute time interval between each context. Findings: The results of ANOVA with repeated measures showed a significant difference between the different research contexts. By presenting the secondary task, the level of perceived difficulty increased and it decreased with the induction of stereotypes, and in accordance with the level of perceived difficulty, agility performance had a significant positive change compared to other contexts (P<0.001). Conclusion: The results of the research showed that inducing gender stereotypes improves performance and presenting secondary tasks disrupts performance. It was also found that the induction of positive stereotype moderates the destructive effects of the secondary task. According to the results of the present research, gender stereotyping can moderate the dysfunction caused by the presentation of the secondary task in competitive and sensitive contexts. Educators can use positive gender stereotype induction to eliminate the harmful effects of the secondary task.
