Background: Colors can play an effective role in the level of attention, arousal, anxiety, and motivation of learners in learning. Aim: The purpose of this study was to investigate the effect of the color of educational tools and teaching aids and the role of trait anxiety on learning futsal inside kick skills. Materials and Methods: Sixty football school participants aged 10-12 years, who, had no experience in futsal matches, according to the type of color (warm and cool) and the level of anxiety (high and low) in four groups were selected. The participants performed 135 trials during three acquisition sessions including 3 blocks of 15 and they rested for 5 sec between each attempt and 2 min between each block. At the end of the last session, the acquisition test and after 48 hours, the retention test, and after 15 min, the transfer test were performed in the same session in the presence of the spectators. To analysis the data, from variance analysis tests with repeated measurements were used. For the effectiveness of color in the acquisition phase, the two-way variance analysis test was used to compare the groups at the significant level of P<0.05. Results: The effect of training sessions(P<0.001) and the interactive effect of color and anxiety (P<0.028) and test stages (P<0.001) are significant and the changes in the progress of the groups did not take place in the same way. In subjects with high anxiety, the cool color group had better progress than the warm color group, and in low anxiety subjects, the warm color group had better progress than the cool color group. Therefore, in learning futsal side kick skill in subjects with high and low trait anxiety, the color of the tool is known as an effective factor. Conclusion: The use of a variety of training programs along with the color of the tool can improve the learning of futsal inside kick in teenagers with high and low trait anxiety.

Background: In recent years, the examination of the impact of various types of different exercises as the key influential components on balance has gained considerable popularity. Numerous studies have investigated the effects of diverse exercise modalities on the enhancement of balance abilities. Aim: The aim of this research was to compare the effects of different types of learning (explicit and implicit) on the balance of elderly individuals. Materials and Methods: Forty-two elderly participants (both women and men), after initial health assessments and medical history reviews, voluntarily participated in the study. They were randomly assigned to three groups: explicit learning group (14 participants), implicit learning group (14 participants), and control group (14 participants). Before the implementation of the targeted learning exercises, the static balance of the participants was assessed using the Flamingo Test, and dynamic balance was measured using the Timed Up and Go (TUG) test. After two sessions of learning exercises, the participants were reassessed. Statistical analysis was conducted using descriptive statistics (mean and standard deviation) and inferential statistics (ANCOVA and Shapiro-Wilk test) at a significance level of P<0.05. Results: The findings indicated that there was no significant difference between the groups in the pre-test, but after performing the learning exercises, the static balance of the implicit learning group showed a statistically significant improvement compared to the explicit learning group and the control group. However, there was no significant increase in dynamic balance performance in any of the groups. Conclusion: The results of this study support the claim that implicit learning exercises can have a positive and significant impact on the static balance performance of elderly individuals. It was also shown that implicit cognitive training had no effect on dynamic balance, which may indicate the important role of other variables such as motor control abilities.

Background: Physical education (PE) plays a crucial role in fostering an enjoyment of physical activity (PA) and developing physical literacy in students. This, in turn, contributes to lifelong health and well-being. Aim: The study explored the association between teachers’ perceived physical literacy, students' enjoyment of PA, and physical literacy. This was done by investigating the mediating role of teachers' self-efficacy in teaching PE. Materials and Methods: The sample included 40 physical education teachers and 100 students in 7 to 9 grades of secondary education, totaling 140 participants. The teachers completed the Physical Education Teachers' Perceived Physical Literacy Instrument (PPLI) and Teacher Self-Efficacy Scale (TSES). In contrast, the students completed the Physical Activity Enjoyment Scale (PACES) and Adolescent Physical Literacy Questionnaire (APLQ). Results The results from the structural equation modeling confirmed the model's fit and showed that teachers’ perceived physical literacy and self-efficacy have a direct and positive relationship with students' enjoyment of PA and physical literacy. Additionally, teachers' self-efficacy indirectly mediated the relationship between teachers’ perceived physical literacy and students' enjoyment of PA and physical literacy. Conclusion: The results underscore the importance of teachers' perceived physical literacy in fostering positive student outcomes concerning PA by mediating the role of teaching self-efficacy.

This study investigates what effect stadium elevation has on the win-loss performance of home teams in major college football. Despite extensive research on factors that influence home-field advantage in sports, the potential impact of altitude on the performance of college football teams has not been thoroughly explored. Therefore, the purpose of this study is to compare the records of institutions playing home games at the highest elevation stadiums with national averages. In contrast to its effect on sports like international soccer or running, results indicate that teams playing in stadiums at higher elevations have no significant difference in win-loss percentage than the national average as findings suggest that altitude does not play a significant role in the performance of FBS teams. Unlike soccer teams playing in high-altitude cities or runners training in the mountains prior to racing at lower levels, this study concludes that playing in stadiums located at higher elevations does not significantly impact win-loss percentage of college football teams. This study contributes to the understanding of the factors that influence home-field advantage in college football and the limited impact of altitude on college football.
