Job demands-resources model and burnout in physical education teaching: A mixed-method sequential explanatory study Kiremitçi, Olcay; Boz, Berkcan; Çakır Yıldız, Lale ACKGROUND: While literature includes a number of studies about burnout in teaching, investigations on teaching fieldspecific perspective remain limited. Research is needed to improve practical implications based on structured theoretical models and methodological basis that focusses on the unique environment of PE teaching field and causal factors behind burnout. OBJECTIVE: The present study aimed to examine burnout among physical education (PE) teachers based on the job demands-resources (J-DR) model. METHODS: A sequential explanatory mixed design was conducted in the study. 173 teachers replied to questionnaires, of which 14 teachers thereafter participated in semi-structured interviews. Demographic information form, Maslach Burnout Inventory, and J-DR scale for PE teachers were used, as well as an interview form. 173 teachers were first asked to report demographic information, and score Maslach Burnout Inventory and J-DR scale. Then a subsample group (n = 14) was identified/sampled for a semi-structured interview. Canonical correlation and constant comparative analysis were used to unpack the data. RESULTS: Teachers' states of burnout varied, and physical, organisational, and socio-cultural resources were closely related with burnout levels. Demands that cause pressure on burnout were determined as paperwork and bureaucracy, student-related factors, and pandemic-related experiences. In addition to supporting the general model, specific J-DR factors for PE teaching were observed that is linked with burnout. CONCLUSION: J-DR factors that might lead to negative conditions in the teaching environment should be considered, and field-specific factors should be focused on through arrangements to increase teaching efficiency and improve the quality of PE teachers' professional life.

Acute effect of moderate and high-intensity interval exercises on asprosin and BDNF levels in inactive normal weight and obese individuals Ceylan, Halil İbrahim; Öztürk , Mehmet Ertuğrul; Öztürk, Deniz; Saygın, Özcan This study aimed to examine the acute effects of moderate-intensity aerobic and high-intensity interval exercise protocols on Asprosin and Brain-Derived Neurotrophic Factor (BDNF) levels in inactive normal weight and obese individuals. A total of 20 male individuals aged 18-65 years, ten normal weight (NW) (Body Mass Index (BMI): 18.5-24.99 kg/m2) and 10 obese (Ob) (BMI: 24.99-35.00 kg/m2) participated in this study, voluntarily. Moderate aerobic exercise (AE) (main circuit 30 min, between 40 and 59% of Heart Rate Reserve: HRR) and High-Intensity Interval exercise (HIIE) running protocols (main circuit 20 min, between 75 and 90% of the HRR for 1 min*10 times, and 1-min active rest at 30% of the HRR) was applied to the volunteer participants in the morning hours (08.00-10.00 a.m.), following the night fasting (at least 8-10 h) for at least 3 days between each other. Blood samples were collected from the participants before and immediately after each exercise protocol, and serum asprosin and BDNF hormone levels were determined by Enzyme-Linked Immunosorbent Assay" method. Basal serum asprosin was found to be significantly higher in the Ob group compared to the NW group (p < .001), while the basal serum BDNF hormone was found to be lower (p < 0.05). It was observed that the serum asprosin level of both groups decreased significantly after both AE and HIIE protocols (p < 0.05). In addition, there was a significantly higher decrease in serum asprosin level in the Ob group compared to the NW group after HIIE protocol. For the Ob group, serum BDNF level increased considerably after HIIE protocol compared to AE protocol (p < 0.05). Serum asprosin was found to be higher in the Ob group, while the serum BDNF was found to be lower. In addition, the acute exercises of different intensity significantly affected hormones that regulate appetite metabolism. In particular, it was observed that the HIIE protocol had a greater effect on the regulation of appetite (hunger-satiety) in the Ob group. This result can be taken into account when planning training programs for these individuals.

Education of Cognitive of Emotion Regulation on Athletic Performance of High School Male Students SALEHIAN, MIR HAMID; Gürsoy, Recep; ASADI, TAYEBEH BANI; GHANATI, PARINAZ The main purpose of this research was to study the effect of emotional regulation on the athletic performance. The present research was descriptive-correlational in terms of research method and applied in terms of purpose and survey in terms of data collection method, which was conducted in the field. The statistical population of this study includes all male athletes in Bayburt in team (football, volleyball and handball) and individual (track and field, judo), with an average age of 16 +/- 2.6 years old, from which 30 students were randomly selected Voluntarily. Data collection tools consisted of three questionnaires: Charbonneau exercise performance questionnaire (2001) and emotional cognitive regulation questionnaire (Garnowski et al., 2001). The validity of these two questionnaires was 0.82 and 0.91 by Cronbach's alpha coefficient in this study. Regression correlation test was used to test the hypotheses .The results showed that the athletic performance of high school male students can be affected by cognitive emotion regulation. By training the emotions of high school male students their performance get better and cope with the challenges.

Acute effect of tabata workout on heart rate and blood lactate accumulation of female futsal players

Acute effect of tabata workout on heart rate and blood lactate accumulation of female futsal players Mülazimoğlu, Olcay; Boyacı, Abdurrahman; Afyon, Yakup Akif; Çelikbilek, Sinan Introduction: Tabata training programs are characterized as high-intensity interval training. The compatibility of the physiological load created by this exercise program on futsal players with the characteristics of futsal is still being debated. This study aims to investigate the acute effect of Tabata training on heart rate and blood lactate accumulation in female futsal players. Materials and methods: A total of 12 female athletes (age: 20.33±0.89 yrs.) participated in the study. Subjects performed 2 sets (segments) of Tabata exercises, each of which consisted of 4 different movements of 20 seconds, with 10 seconds recovery intervals. The heart rate (HR) and blood lactate (BLa) levels of the athletes were measured before (pre) and after (post) each set of Tabata workout. Paired sample t-test was used to compare the difference in HR responses and BLa accumulation between the before-after of sets in Tabata exercise. Significant level was defined as p ≤0.05. Results: A significant difference was found between the mean HR pre and post both sets (P<0.01). Participants' exercise pretest heart rate values increased from approximately 60% to 95% of HRmax%. There was a significant difference in BLa (13.36±3.70, 16.64±3.04 mmol.l-1; t=5.27; P[removed]0.05). It was observed that the increase in BLa (5.76±2.90; 16.64±3.04 mmol.l-1) of the 2nd set post-test values increased approximately three times compared to the 1st set pre-test. Conclusion: The metabolic load level it creates on the athlete shows that this workout method can be used to increase anaerobic endurance and capacity.
