Abstract
Today, commercial companies have accepted that sportsponsoring can act as a powerful tool for promoting their value. This study examines the impact of sponsorship aspects on brand equity of sponsor while researching about Hamrah Aval Company. The research method is descriptive-analytical, and is practical in terms of research target. The research is implemented using Structural Equation Modeling (SEM). The statistical population of the research is consisted of the fans of Perspolis and Esteghlal football teams who are members of HamrahAval fan system.393 questionnaires were collected using stratified random sampling in the field.A researcher made questionnaire was used to collect primary data.The validity of the questionnaire was checked using confirmation of sport management and marketing professors, and its reliability was tested using Cronbach's alpha (α=0.95), and construct validity was made through confirmatory factor analysis.The findings showed that the suggested research model had a good fitness and all of the six aspects of sport sponsorship had a significant effect on the brand equity of the sponsor, and all the research hypotheses were confirmed.According to the findings, it is recommendedthat brand sponsors plan marketing activities (TV coverage and advertisements) to promote their brand equities.

Abstract
The aim of this study was to investigate the effect of voluntary and forced exercise and off-line periods on consolidation of implicit motor memory. This study was a quasi-experimental method and the statistical population consisted of girl students of Shiraz University. So 30 non-athlete girl students with mental health, and without neural disease background or sleep disorders were voluntarily participated in the study. After determining the memory function, they were divided into 3 experimental groups with 6, 24 and 48 hours off-line periods. The research consisted of 2 stages and each stage included of acquisition, physical exercises (first stage voluntary and the second one forced) and retention (memory test) sessions. The intermittent chain reaction time assignment was used to measure motor memory changes. The Analysis of Variance (ANOVA) with repeated measure, with the significant level of p≤0.05, was used to answer the questions of research. The results showed that each of the 3 off-line periods had positive effects on consolidation of implicit motor memory, but there were no significant difference among them. The effect of voluntary and forced exercise on implicit motor memory consolidation, showed a significant difference in favor of voluntary exercise.

Abstract
The purpose of this study was to investigate the effect of practice variability in physical compared with observational practice on golf putting performance. To this end, 50 male right-handed students (25±3.7 years) participated in this study. Participants were randomly divided into 5 groups (physical constant, physical variable, observational constant, observational variable, and control). During acquisition, the physical variable group randomly performed 50 trials from 5 different starting points to 2 different targets, but the physical constant group performed 50 trials from one starting point to one predetermined target. The observational variable and constant groups observed the performance of the physical variable and constant groups, respectively. The control group just participated in pre-and post-tests. Participants performed a test just like the pre-test 10 minutes and also 24 hours after practice. Putting accuracy was measured as the dependent measure. Results showed that variability of practice had a positive effect on performance than constant practice in physical and observational conditions. Maybe the similar underlying mechanisms and also the similar feedback effects resulted in the higher performance of the variable group than the constant group in physical performance and action observation.

Abstract
Aim: One of the recent research challenges in the field of attentional focus instructions, are the study of its effects on the performance of elite athletes in continuous tasks. The aim of this study was to compare the effects of different attentional focus instructions on performance of agility in elite futsal players.
Methods Participants included 12 elite futsal players (mean age 23.91±1.56) that were selected from the first league of Division Qom via convenience sampling method. Participants were asked to perform the agility L run test under three attentional focus instructions (the internal, external and control) in three trials. Rrepeated measure Analysis of Variance and paired t test were used for analysis of data.
Result: The results showed a significant effects of the type of attentional focus instructions on test execution time. Analyses showed that performance in the external focus of attention was higher than the internal focus conditions. Also, the result demonstrated that there is no significant difference between internal focus of attention and control conditions, and also between external focus of attention and control condition.
Conclusion: The results of this study provide evidence that in skilled athletes, executing the continuous tasks improve through verbal instructions that conduct focus of attention externally.

Abstract
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

Abstract
Background: Firefighters encounter critical and hazardous situations that necessitate optimal and rapid performance during emergencies. Given the complexity of their responsibilities and the psychological pressures stemming from daily tasks, it is crucial to investigate methods to enhance their performance. This study aimed to assess the impact of mindfulness exercises on the coordination, executive functions, and specialized motor skills of firefighters.
Aim: The study utilized a semi-experimental design with pre-test and post-test assessments.
Methodology: This study was a quasi-experimental design with a pre-test and post-test involving a control group. The statistical population consisted of firefighters from fire stations in Shiraz province, and six stations were selected using a multi-stage cluster sampling method from a total of 24 stations. Thirty firefighters were matched based on their pre-test scores and randomly divided into two groups of 15 each: a control group and an experimental group. The experimental group received mindfulness training for eight weeks, with three 30-minute sessions each week. The assessment tools included the Grooved Pegboard Test, the N-back Test, and specialized motor skill tests for firefighters. The data were analyzed using Analysis of Covariance (ANCOVA).
Results: The mindfulness intervention significantly improved the experimental group's performance in coordination (p < 0.001), specialized motor skills (p = 0.044), and executive functions (p < 0.001). However, no significant difference was observed in pipe opening/closing tasks (p = 0.087).
Conclusion: Mindfulness exercises may enhance critical abilities in firefighters and could inform the design of effective training programs.
