Objective : Basketball is a sport characterized by open skills, where actions are unpredictable and dynamics are constantly shifting, leading professional players to experience varying levels of physical and mental fatigue. This study aimed to explore and compare how mindfulness and music training affect physical and mental fatigue in elite basketball players. Method: In this quasi-experimental research, 27 elite basketball players were randomly assigned to either a mindfulness-based training group, a music-based training group, or a control group. Blood samples were taken under fasting conditions to assess the study variables before and after the intervention. Data analysis involved one-way analysis of variance (ACNOVA), paired t-tests with a significance threshold (P ≤ 0.05), and the Bonferroni post hoc test to identify intra-group and inter-group differences. SPSS version 27 was utilized for these analyses. Results : When comparing the groups, there was no significant difference in the impact of mindfulness and music on physical fatigue at a significance level (P ≤ 0.05). Similarly, the effect of mindfulness and music on changes in inflammatory markers such as lactate dehydrogenase, creatine kinase, and C-reactive protein was not significantly different at the same significance level. However, the effect of mindfulness and music on mental fatigue showed a significant difference at a significance level (P ≤ 0.05), indicating that mindfulness significantly reduces psychological fatigue. Conclusions : The findings of this study revealed no significant difference between the effectiveness of mindfulness-based training and music in terms of physical fatigue and changes in serum levels of lactate dehydrogenase, creatine kinase, and C-reactive protein. However, in the area of mental fatigue, mindfulness-based training demonstrated a significant reduction in mental fatigue in the post-test. 

Locomotive Syndrome (LS) is a prevalent condition among older adults. It significantly impacts the quality of life and increases the risk of falls, fractures, and functional decline. This study aimed to compare the effectiveness of two exercise programs, Vivifrail and Locotra, on improving walking speed in elderly individuals with LS. Thirty elderly women aged 65 and older from the Ranginkamanesepid Day Care Center in Isfahan, Iran, participated in this randomized controlled trial, divided into two groups for an eight-week intervention, conducted three times a week. The primary outcome was the 6-meter walking time test, measured before and after the intervention. Both exercise programs demonstrated improvements in walking speed post-intervention; however, no statistically significant difference was found between the two groups. The Vivifrail group had a mean walking time post-test, while the Locotra group also showed improvement. The effect sizes indicated that both programs were effective but did not significantly outperform each other. Both Vivifrail and Locotra exercise programs are beneficial for enhancing walking speed in elderly individuals with LS, and given the lack of significant differences between the two interventions, healthcare providers may consider either program as a viable option for improving mobility in this population.

The purpose of this study was to assess the effect of brand association on the brand positioning of football clubs in the Iranian premier league with the mediating role of fan-team identification. The present study is a descriptive and correlational study that has been conducted in the field. The research population of the study included football fans of popular football clubs in the Iranian premier league. Based on the formula for the SEM approach , 208 fans were selected through purposive sampling. Brand association, brand positioning, as well as fan-team identification Questionnaire, were used to collect data. The validity of the tool was calculated and confirmed based on content and structural validity, and the reliability was assessed according to Cronbach's alpha and composite reliability. Structural equation modeling via PLS was used to test the research hypotheses. The results showed that brand association had a significant effect on both brand positioning (β= 0.23) and fan-team identification (β= 0.31). The results also confirmed the positive and significant effect of fan-team identification on the brand positioning of football clubs in the Iranian premier league (β= 0.29). Moreover, based on the Sobel test, brand association through fan-team identification was effective on the brand positioning. The value of the GOF also indicated the proper fitness of the research model. This study is one of the few types of research that combines and examines brand associations, fan-team identification, and brand positioning through a comprehensive model in the field of Iranian sports.
