Background: Myofascial pain syndrome (MPS) is caused by sensitive spot in muscles that are known as trigger points (TPs) which can have complications that can affect person's quality of life. Massage and self-myofascial-release (SMR) are two non-invasive techniques which are used to reduce the side effects of TPs. Aim: The present study is intending to compare the effect of the two mentioned techniques in reducing complications caused by TPs such as reduced ROM and pain in women with MPS of the trapezius muscle. Materials and Methods: 45 women aged 20-25 years with active TPs in the trapezius muscle were randomly divided into two experimental groups and one control group. The research process was one week which consists of pretest, 5 days intervention and post-test. The variables included pain measured by OBER questionnaire and ROM of neck measured by goniometer. Results: The results of the study showed that massage can have a significant effect on the ROM of neck including neck flexion (P= 0.00), extension (P= 0.00), left (P= 0.00) and right (P= 0.004) lateral flexion and left (P=0.00) and right (P= 0.04) rotation (P<0.05). Both massage and SMR interventions had a significant effect on reducing pain measured by OBER questionnaire (P<0.05). Conclusion: Findings of this study showed that myofascial release massage can have better effects on increasing neck ROM. Both treatment modalities are useful in reducing pain. Based on the obtained results, we recommend that specialists use massage intervention instead of myofascial self-release (SMR) for individuals suffering from MPS and neck pain, in order to achieve quicker and more extensive results.

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: Alzheimer’s disease (AD), the most prevalent neurodegenerative disorder, is characterized by amyloid-beta (Aβ) plaque accumulation, neurofibrillary tangles, neuronal death, inflammation, and oxidative stress.Aim: We investigated the effects of treadmill exercise and intranasal insulin on spatial memory, blood glucose level, and Physical growth indicators including weight, head circumference, and tail length.Materials and Methods: Seventy-two male Wistar rats, aged 8 weeks were into 9 gtoups at random (control, Sham, Aβ, Aβ + EX, Aβ +PINS, Aβ + INST, Aβ + EX + PINS, Aβ + EX + INST, and Aβ + EX + PINS + INST). We discovered that rats receiving Aβ25-35 had impaired spatial memory, which was associated with weight loss, brain growth retardation, Tail Length, and elevated blood glucose levels. Data from each trial was statistically analyzed using IBM SPSSStatistics 22 software, Two-way ANOVA, and post-hoc analysis Tukey test. The cut-off for statistical significance was P≤0.05.Results: Our results show that the improvement of spatial memory due to the improvement of metabolism and growth indicators can be affected by pretreatment exercise and intranasal insulin. Also, exercise training and intranasal insulin improved spatial memory and prevented brain growth retardation, increased blood glucose, weight loss, and tail length in animals treated with Aβ25-35.Conclusion: Exercise can amplify the positive benefits of intranasal insulin treatment on memory. The results of our research showed that exercise and insulin can prevent brain growth retardation and prevent spatial memory disorders by improving glucose metabolismy.

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: Research shows that new technologies have increased the tendency to use electronic sports in physical education activities. Studies on physical education activities and e-sports are relatively new and scattered in their focus. However, universities and professionals are growing interested in further research in this area. Aim: The purpose of this study is to systematically review the research done in e-sports and physical education. Materials and Methods: A search was made using EBSCO, Scopus, and Web of Science databases to collect information on the articles. More than 250 scientific articles from 2000 to 2024 were reviewed. The keywords used were: ("Internet sports" or "electronic sports" or "online sports" or "virtual sports" or "E-sport) and ("physical training" or "sports training" or "fitness training" or "Exercise instruction" or "Sports education" or "physical education"). After removing duplicates, 200 articles were screened by reviewing titles and abstracts, resulting in the exclusion of 100 articles that did not meet the inclusion criteria related to integrating electronic sports and physical education. The full texts of the remaining 100 articles were assessed, leading to the exclusion of 36 more articles due to insufficient data or lack of relevance, leaving 64 articles selected for detailed analysis based on their comprehensive coverage and relevance to the study. Then, the selected items were fully studied and finalized, and the items that were more complete than the others were chosen as references. Conclusion: The study identified critical organizational, technological, individual, and environmental factors influencing the implementation of e-sports. It also highlighted nine mediators’ factors essential for effective execution. Strategies like gamification, e-sport fitness challenges, cross-training, team building, health education, e-sport analysis, and smartening education were proposed to support the model's implementation. The expected outcomes of applying this model in physical education include improved cognitive skills, increased physical activity, enhanced social interaction, inclusivity, and technology skill integration. The study emphasizes that considering these factors and strategies will aid in successfully implementing the conceptual model.
