Background: The physical fitness is essential for wrestlers to perform successfully. The Tabata Protocol can be appropriate to develop these physical qualities.Aim: This study aims to investigate the effects of high-intensity interval training using “Tabata  protocol” on the physical fitness of teenage wrestlers.Material and Methods: 16 participants were randomly assigned to two groups of Tabata training (n=8) and the control group (n=8). All mentioned variables were measured before and after 4 weeks of the intervention. Tabata training group performed Tabata protocol in 2- 3 sets of 8 exercises with 20 sec of training and 10 sec of rest. The control group kept up their normal training routine during the same time. Physical fitness components were measured. The collected data were statistically analyzed by an independent t-test at a significance level of P>0.05.Results: Wrestlers in both groups significantly increased physical fitness components except flexibility (P<0.05). Tabata training was significantly more efficient in endurance of core muscle (P= 0.019, ES= 0.490) and upper body strength (P= 0.001, ES= 0.490) than control group (P<0.05). Also, results showed that for leg explosive power, only Tabata training had a positive effect (P= 0.026, ES=0.541).Conclusions: Our results suggest that wrestlers after Tabata protocol interventions can obtain better physical fitness, and event time benefits with more efficient performance and time-efficient manner compared with control group.

This paper explores the impact of modernization and globalization on Iranians' cultural and identity-based relationship with the environment, resulting in a loss of mental and semantic dimensions. This has led to environmental numbness and disregard for the natural world. The study argues that virtual education can complement holistic education and provide a platform for Iranians to learn about the mental and semantic aspects of their relationship with nature, thereby restoring their sense of connection to the natural world. The paper suggests that virtual education can help develop environmental awareness, critical thinking skills, and social responsibility while providing access to educational resources for individuals who may be geographically or socially isolated. Integrating virtual education into formal and non-formal education in Iran can play a critical role in promoting sustainable development, addressing environmental challenges, and preserving cultural identity. The study uses qualitative and descriptive research methods.

The first paragraph of Article 10 of the European Convention on Human Rights (ECHR) recognizes the right to freedom of expression and prohibits party states from any arbitrary interference. The second paragraph, emphasizing that exercising this right comes with certain duties and responsibilities, authorizes the party states to restrict this right for their citizens if the specified conditions are met. One such condition is achieving one of the legitimate aims listed therein. The courts of Turkey, as a member state bound by the ECHR, have invoked these goals to justify their decisions regarding the restriction of citizens' right to freedom of expression. Nevertheless, convicted individuals who appeal these rulings before the European Court of Human Rights argue that no such legitimate aim existed, and that their right to freedom of expression has been violated. This study investigates the primary challenges faced by Turkish courts in invoking legitimate aims as justifications for restricting freedom of expression. It also elucidates the precise meaning and conditions for the eligibility of these goals based on the interpretation provided by the European Court of Human Rights.

Background: Shoulder impingement syndrome is a common complication that causes pain and disability, functional limitations and reduced quality of life. This syndrome is usually seen in people who are involved in activities and sports involving rotating movements above the head, including bodybuilders. Meanwhile, corrective exercises have been considered as an intervention in the rehabilitation of the condition. Exercises based on National Academy of Sports Medicine (NASM) principles are known as one of the new methods in the rehabilitation and prevention of sports injuries.Aim: The purpose of this study was to investigate the effect and permanence of corrective exercises on pain intensity, functional disability and kinematic parameters of bodybuilders with shoulder impingement syndrome.Materials and Methods: In this semi-experimental research with a pre-test-post-test design, 20 male bodybuilders with shoulder impingement syndrome were randomly assigned in two groups; corrective exercises as the experimental group (n=10) and control group (n=10). Visual Analog Scale (VAS) questionnaire was used for pain intensity. Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire was used for functional disability. Kinovea software was used to kinematic parameters. The evaluations carried out during three stages: the pre-test, the first post-test (after 8 weeks) and the second post-test (after 12 weeks). Data were analyzed using descriptive statistics, repeated measures analysis of variance (ANOVA) at a significance level of 0.05 using SPSS version 20 software.Results: The findings showed that after 8 weeks of corrective exercises, there were significant changes in pain intensity and functional disability in the experimental group (P<0.05). Also, significant changes in shoulder biomechanical parameters during flexion, abduction, external rotation and internal rotation movements were observed between the two groups (P<0.05). Permanence of the exercises in the studied variables after 12 weeks showed a significant difference between the two groups (P<0.05).Conclusion: According to the obtained results, it can be stated that a course of NASM exercises reduced shoulder pain, improved functional disability and improved kinematic parameters in male bodybuilders with shoulder impingement syndrome.
