Article Citation - WoS: 29Citation - Scopus: 32Effects of Exercise Training on Anxiety in Diabetic Rats(Elsevier, 2019) Caliskan, Hasan; Akat, Firat; Tatar, Yakup; Zaloglu, Nezahet; Dursun, Ali Dogan; Bastug, Metin; Ficicilar, HakanDiabetes mellitus (DM) is a common health problem, which manifests itself with chronic hyperglycemia and impaired insulin action. The prevalence of anxiety disorders tends to be high in the diabetic population. Exercise has a well-known anxiolytic effect, also demonstrated on rodents, but the effect of exercise on the DM-induced anxiety is still unknown. Female, Wistar albino rats were randomly divided into four groups (n=8) (C; EX; DM; DM+EX). DM was induced by injection (i.p.; 50 mg/kg) of Streptozotocin (STZ). Rats exercised in moderate intensity on the treadmill (15m/min; 5 degrees; 30 min) for 5 weeks. Anxiety-like behavior (ALB) was evaluated by Open field test (OFT) and Elevated Plus Maze (EPM). According to OFT, central time and central entry have increased with in EX but not in DM+EX. There was no difference between C and DM. Central latency time didn't differ among groups. Unsupported rearing increased in both EX and DM+EX. There was no significant decrease in DM. Freezing time was significantly increased in the DM group. Exercise training reduced freezing time both in diabetic and non-diabetic animals. EPM results were similar. Time spent in open arm was increased significantly in exercise groups compared to their sedentary matches, and freezing time data were also parallel to OFT. Our study revealed that diabetes had shown an anxiogenic effect, which was not severe, and it only manifested itself on some behavioral parameters. Exercise training was reduced anxiety-like behavior both in diabetic and non-diabetic rats. However, because of the nature of exercise studies, it is hard to separate the anxiolytic effect of exercise from the alteration of locomotion.Article Validity and Reliability of Turkish Version of the Physical Activity Enjoyment Scale-8 Items in Adults(SAGE Publications Ltd, 2025) Çınar-Medeni, Ö.; İncekas, C.; Özcan, A.; Ozdemir, F.; Ulusoy, B.; Can Karahan, Z.Background: The enjoyment of physical activity significantly influences participation in sports and various forms of physical activity. This study aims to conduct a cross-cultural adaptation and assess the reliability and validity of the Turkish version of the Physical Activity Enjoyment Scale-8 Items (PACES-8). Methods: A total of 120 participants were included in the study. A standardized translation process was followed. Criterion-related validity was assessed using the Behavioral Regulation in Exercise Questionnaire-2 (BREQ-2) and the International Physical Activity Questionnaire-Short Form (IPAQ). All participants were evaluated in two sessions following a 15-min walk. Sociodemographic data, PACES-8, BREQ-2, and IPAQ questionnaires were administered during the initial measurement, while the second measurement focused solely on assessing physical activity enjoyment. Results: Exploratory factor analysis revealed factor loadings ranging from 0.78 to 0.94, indicating a strong single-factor structure. The model demonstrated a good fit to the data (Chi-Square Goodness of Fit Test (χ²/df) = 3.26, p < 0.001; Comparative Fit Index = 0.96; Tucker-Lewis Index = 0.93). The Cronbach's alpha coefficient was 0.95, reflecting excellent internal consistency. PACES-8 showed a low correlation with the external regulation score of BREQ-2 (r = -0.24, p = 0.03) and the physical activity score (IPAQ score) of participants (r = 0.24, p = 0.007). Conclusions: The findings suggest that the Turkish version of PACES-8 is a unidimensional, reliable, and valid instrument for measuring enjoyment of physical activity. Further research is needed to assess its validity across different populations. © 2025 Elsevier B.V., All rights reserved.
