Earthquakes are calamities of devastating nature that induce longterm post traumatic stress on affected victims. As such, they are recognized worldwide as being huge sources of stress. In this research study, the first objective is to assess the level of trauma and earthquake stress of university students who exercise and those who do not. This study utilized the descriptive survey research method. The sample comprised 378 male and 300 female students who experienced the socially detrimental 7.7 Mw and 7.6 Mw earthquakes in Turkey on February 6, 2023. The data were both face-to-face and via computer-administered questionnaire with the tools of “Post-Earthquake Trauma Level Scale” and “Earthquake Stress Coping Strategies Scale.” After checking for normality, the parametric tests were used, the t-test to compare two groups of data, and ANOVA for three or more groups of data. Furthermore, Pearson correlation analyses were performed to compare the interactions between students who exercise and those who do not. The study found that gender affected trauma levels, with female students (X = 73.483) exhibiting significantly higher trauma levels than male students (X = 68.799) (p < 0.001). Students who engaged in regular physical activity (X = 67.71) were found to have lower trauma levels compared to those who did not exercise (X = 71.97). Participants who feared being caught by the earthquake at home or school (X = 73.32), experienced the loss of someone close (X = 88.10) or believed that adequate precautions against the earthquake had not been taken (X = 71.73) had higher trauma scores. According to the results of the ANOVA test, students from the Departments of Sports Sciences (X = 69.78) and Religious Studies (X = 69.63) were observed to have lower trauma levels. Pearson correlation analysis showed a positive and moderate relationship between trauma levels and earthquake stress coping strategies among students who engaged in regular physical activity (r = .176, p < 0.01). The research identified that factors such as gender, regular exercise, the experience of losing a loved one, and the perception that insufficient precautions were taken all significantly influence trauma levels. Moreover, the findings highlighted that regular physical exercise serves as an effective strategy for managing and coping with trauma.

The aim of this study is to evaluate the relationship between exercise addiction and behavioural regulation in exercise and substance addiction awareness of weightlifting and boxing athletes and to examine these data in terms of demographic variables. The research group consists of 333 participants. “Exercise Addiction Scale”, “Behavioural Regulations in Exercise-2” and “Substance Addiction Awareness Scale” were used for data collection. Percentage and frequency distributions and Pearson Correlation Analysis were applied in the analysis of the data. According to the results of the research, significant positive correlation was found between the Exercise Addiction Scale total score and the Substance Addiction Awareness Scale total score, and the Behavioural Regulations in Exercise-2 total score. In this context, when the motivation that occurs during exercise becomes a compulsive action, it is thought that exercise addiction starts in the individual and that the substance addiction awareness of exercise addicts is higher.

The game of football, played within the framework of certain rules, has also become a large sector in terms of sports economy. It is stated that the highest level of performance and all physiological characteristics should be analyzed in the football branch, as it consists of various movement sequences and includes versatile skills. In the literature, performance is defined as the score obtained from physical, physiological and biomotor data. In this context, this study aims to examine the relationship between MaxVo2 values and Various Parameters of football players playing in an amateur football team. In the study where the relationship between MaxVo2 values of football players and various parameters was examined, the correlational method, one of the quantitative research methods, was used. The research group consists of football players playing for Ağasar Çepni Football Club in the Trabzon 1st Amateur Football League. Average age of participants; 26.06±4.56, average height; 175.17±5.74, body weight (kg); It consists of 18 volunteer football players whose age is 73.79±11.11. SPSS.22 program was used in the statistical analysis of the data. Descriptive analyzes of football players were calculated as mean and standard deviation. Relationships between variables were determined using the Pearson correlation test. The significance level was taken as p

Bu araştırmanın amacı, Bartın üniversitesi öğrencilerinin serbest zaman faaliyetlerine yönelik engel ile baş etme stratejileri ve saldırganlık davranışları arasındaki ilişkiyi bazı demografik değişkenlere göre incelemektir. Araştırma ilişkisel tarama modeline göre yürütülmüştür. Örneklem grubu uygun örnekleme yöntemi ile seçilen 299 üniversite öğrencisinden oluşmaktadır. Araştırmada veri toplama araçları olarak araştırmacılar tarafından hazırlanan kişisel bilgi formu, “Serbest Zaman Engelleri ile Baş Etme Stratejileri Ölçeği (SZEBSÖ)” ve “Buss-Perry Saldırganlık Ölçeği (BPSÖ)” kullanılmıştır. Verilerin analizinde SPSS 26.0 paket programı kullanılarak, T-Testi ve Pearson Korelasyon analizleri yapılmıştır. Öğrencilerin cinsiyet değişkenine yönelik SZEBSÖ arasında anlamlı farklılık görülmezken; fiziksel saldırganlık davranışları erkek katılımcıların anlamlı düzeyde yüksek bulunmuştur. Katılımcıların spor türü değişkenine göre SZEBSÖ “kişilerarası ilişkiler” alt boyutunda bireysel spor yapanların lehine anlamlı farklılık bulunmuştur. Katılımcıların yaş değişkenine ile serbest zaman engelleri ile baş etme stratejileri ölçeği arasında anlamlı düzeyde ilişki bulunmamıştır. Ayrıca öğrencilerin yaş değişkeni ile Buss-Perry saldırganlık ölçeği ve “fiziksel saldırganlık” alt boyutunda pozitif yönde ve düşük düzeyde ilişki bulunmuştur. Üniversite öğrencilerinin serbest zaman engelleri ile baş etme stratejileri ölçeği ile Buss-Perry saldırganlık ölçeği arasında negatif ve orta düzeyde ilişki bulunmuştur. Sonuç olarak üniversite öğrencilerinin saldırganlık eğiliminin artması, serbest zaman engellerine yönelik baş etme stratejilerini olumsuz yönde etkilediği söylenebilir. Üniversite öğrencilerinin saldırganlık davranışlarını azaltmaya yönelik programların uygulanması, serbest zaman etkinliklerine katılımlarına katkı sağlayacaktır.

This study aimed to examine the validity and reliability of the AI-based DeepSport application by comparing its outcomes with those from the reference device, OptoJump. The primary dependent variables measured were jump height and anaerobic power during vertical jump assessments. Twelve elite male basketball players voluntarily participated in the study (age = 21.53 ± 1.14 years; sports experience = 6.47 ± 1.01 years). DeepSport uses AI-based image processing from standard cameras, while OptoJump uses optical sensor technology. Both DeepSport and OptoJump systems were utilized to assess participants’ Countermovement Jump (CMJ) and Squat Jump (SJ) performances. A G*Power (version 3.1.9.7) analysis determined the required sample size, adopting a 95% confidence level, 90% test power, and an effect size of 0.25. Validity assessments were conducted using Bland-Altman plots and ordinary least products (OLP) regression analysis, while reliability was evaluated through intraclass correlation coefficient (ICC), coefficient of variation (CV), standard error of measurement (SEM), and smallest detectable change (SDC) analyses. DeepSport showed excellent reliability in CMJ and SJ tests with ICC values > 0.90, and CV ranged between 2.12% and 4.95%. Results were consistent with OptoJump, showing no significant differences according to t-test results (p > 0.05). Bland–Altman analyses indicated no systematic bias and random distribution. These findings confirm that both DeepSport and OptoJump devices demonstrate high reliability and consistency, suggesting their validity and reliability for use in athlete performance assessments by coaches and athletes.

The aim of this study is to examine the effects of different plyometric training methods on the biomotor and taekwondo technical performance of 14-16-year-old taekwondo athletes. The study utilized two different training methods: plyometric exercises on sand and plyometric exercises on taekwondo mats, with a control group performing only regular taekwondo training. The study included 66 athletes, all with at least 5 years of taekwondo experience, from Trabzon, Turkey, in 2024. Participants were divided into two experimental groups: Group 1, performing plyometric exercises on sand, and Group 2, performing plyometric exercises on taekwondo mats. After an 8-week training program, biomotor and technical performance tests were applied to all groups for comparison. The data were tested for normal distribution using the Kolmogorov-Smirnov test, and since the data did not show normal distribution, non-parametric tests were used for analysis. Wilcoxon tests were applied for within-group comparisons, while Kruskal-Wallis tests were used for between-group comparisons. In cases where significant differences were found, Posthoc multiple comparison tests with Bonferroni correction were used to identify which groups showed the differences. The results showed that all groups demonstrated significant improvements in biomotor and technical performance parameters after the training programs. Group 1, the sand-based plyometric training group, showed more pronounced improvements in speed, agility, jump, balance, and technical performance parameters. The findings suggest that sand-based plyometric training has a significant impact on sports requiring speed, power, endurance, and technical skills, such as taekwondo.
