Article Spor Medyası Çalışanlarında Suskunluk Sarmalı ve Psikolojik Dayanıklılığın İş Tatmini Üzerindeki Etkisi(2025) Çetinkaya, Gökhan; Karagozoglu, CengızIn this study, it is aimed to determine the effects of spiral of silence, psychological resilience and professional experience levels of sports media employees on their job satisfaction. The population of the study consists of the personnel who are actively working in editorial duties in the sports media. Reached by convenience sampling method, 370 professionals took part in the study on a voluntary basis. In addition to the "Personal Information Form", "Spiral of Silence Scale", "Job Satisfaction Scale" and "Psychological Resilience Scale" were used to collect the data. The collected data were transferred to the SPSS 28 package program. Descriptive statistics, Pearson correlation analysis and hierarchical multiple regression analysis were used to analyse the data. According to the mean scores of the scales applied to the participants, it was determined that the spiral of silence and psychological resilience levels of the sports media employees were at a medium level, while their job satisfaction levels were at a proficient level. Job satisfaction is not affected by the psychological resilience variable. It was found that the opinion expression: engagement sub-dimension of the silence spiral had no effect on job satisfaction. Avoidance of opinion expression was found to be a positive determinant of job satisfaction in sports media employees. Conversely, fear of isolation was found to be a negative determinant of job satisfaction. In addition, it was concluded that professional experience of sports media employees had a positive effect on their job satisfaction.Publication Sabit ve Değişken Şiddet Dağilimli Yüksek Şiddetli İnterval Antrenman Yaklaşimlari: Hangisi Maksimal Oksijen Tüketim Düzeyinde Geçirilen Zamani Artirmada Daha Etkilidir? Anlatımsal bir Derleme(2025) Alp, Egemen; Çabuk, RefıkThe total time spent at high percentages of maximal oxygen uptake (V̇O2max) during a high-intensity interval training (HIIT) session is considered one of the key acute responses for inducing long-term improvements in V̇O2max. Therefore, over the past 15 years, many studies have focused on maximizing the time spent near V̇O2max in constant-intensity HIIT protocols by manipulating variables such as work duration, number of repetitions, recovery duration, and recovery intensity. More recently, however, a limited number of studies have employed strategies that modify the intensity distribution within work bouts in order to increase this time. This narrative review aimed to examine the potential of HIIT strategies with variable intensity distributions to maximize the time spent near V̇O2max compared with constant-intensity HIIT protocols. Accordingly, fast-start, varied-intensity, linearly varying, and stepwise decreasing-intensity protocols were addressed. The findings indicate that, when sufficiently long work bouts are applied to allow V̇O2 to reach maximal levels, variable intensity-distribution HIIT approaches can increase the time spent at V̇O2max compared with traditional constant-intensity protocols. Furthermore, these strategies were found to elicit greater total V̇O2 consumption despite producing similar blood lactate responses and ratings of perceived exertion. These results suggest that HIIT approaches incorporating variable intensity distributions may impose higher aerobic demands.Publication Mekanik Boyun Ağrılı Bireylerde Alt Ekstremite Posterior Plan Kaslarına Foam Roller ile Uygulanan Miyofasyal Gevşetme Tekniğinin Akut Etkisi(2021) Güler, Dilara; Alkan, Mirsad; Besen, Kardelen; Coşkunsu, Dilber KaragözoğluAmaç: Myers tarafından tanımlanan fasyal zincirlerden biri olan Süperfisyal arka zincir (SAZ) ayak parmaklarından başlayıp supraorbital çıkıntıya kadar uzanan fasyal bir banttır.

Developing quantitative instruments grounded in a robust theoretical framework is crucial, as such tools would not only advance research in this field but also contribute to improving the quality of physical education teacher education. This study aims to test the reliability and validity of the Pre-service Physical Education Teachers' Teacher Identity Scale (PPET-TI) to Turkish pre-service physical education teachers. The PPET-TI is a 7-point Likert-type scale comprising 17 items and three subscales: self-definitions, teaching goals, and professional responsibilities. Two hundred fifty pre-service physical education teachers (96 females and 154 males; (x) over bar (age) = 21.25 +/- 2.36) voluntarily participated in the study. Confirmatory Factor Analysis (CFA) and Exploratory Structural Equation Modeling (ESEM) were conducted to evaluate the construct validity. The results of the CFA indicated that S-B chi(2)/df 1.90, CFI 0.95, TLI 0.94, RMSEA 0.06, and SRMR 0.05. The results of the ESEM indicated that S-B chi(2)/df 2.79, CFI 0.98, TLI 0.97, RMSEA 0.08, and SRMR 0.03. The item factor loadings ranged from 0.58 to 0.97 in the CFA and ranged from 0.45 to 0.82 in the ESEM. The findings indicated that the scale exhibited both discriminant and convergent validity, with CR and Cronbach's alpha being strong. An evaluation of the fit indices, item factor loadings, and inter-item relationships revealed that the CFA results were more consistent with the original structure of the scale. Based on all the findings, it can be concluded that the Turkish version of the scale is suitable for assessing the teacher identities of pre-service physical education teachers.Article Mekanik Boyun Ağrılı Bireylerde Alt Ekstremite Posterior Plan Kaslarına Foam Roller İle Uygulanan Miyofasyal Gevşetme Tekniğinin Akut Etkisi(2021) Alkan, Mirsad; Besen, Kardelen; Coşkunsu, Dilber Karagözoğlu; Güler, DilaraAmaç: Myers tarafından tanımlanan fasyal\rzincirlerden biri olan Süperfisyal arka zincir\r(SAZ) ayak parmaklarından başlayıp supraorbital\rçıkıntıya kadar uzanan fasyal bir\rbanttır.
