Background/Objectives: In this study, we aimed to examine the effect of a 12-week dance (Zumba) performance on the fear of happiness and life satisfaction perceptions of high school students studying at boarding school. Methods: The sample group of this study consisted of high school students staying in the school dormitory in the 2022–2023 academic year. A total of 82 students between the ages of 15 and 17, selected by the convenience sampling method, participated in the study, and 41 of the students were selected as the experimental group and 41 as the control group. The Fear of Happiness Scale and Satisfaction with Life Scale were used in the study. The measurement tools were administered as a pre-test one week before the dance program started and as a post-test one week after the end of the program. Two-way ANOVA for mixed measures was applied to determine whether the fear of happiness and life satisfaction pre-test scores were statistically significantly different between the experimental and control groups and to compare the pre-test and post-test difference scores. Results: As a result of the research, it was concluded that the fear of happiness of the students who participated in the dance activity decreased, and their life satisfaction levels increased. These findings emphasize that dance can be an important resource that can increase the psychological well-being of young people. Conclusions: As a result, it can be said that the 12-week dance activity positively affected students’ fear of happiness and life satisfaction perceptions.

Our study is aimed at examining the Ice Hockey National Team players with regard to ACE I/D (rs1799752), ACTN3 (rs1815739), PPARA (rs4253778) and HIF1A (rs11549465) polymorphisms and physical tests. This study was participated by 21 players from ice hockey national team. While ACE I/D (rs1799752) polymorphism was obtained using conventional polymerase chain reaction method (PCR), ACTN3 (rs1815739), PPARA (rs4253778) and HIF1A (rs11549465) polymorphisms were produced by real time polymerase chain reaction method (qPCR). Athletic performance analysis, on the other hand, was based on the assessment of maximal oxygen consumption capacity (VO2max), anaerobic performance, flexibility and strength tests. In our cohort, ACE I/D (rs1799752) polymorphism was determined as 24% genotype II, 33% genotype ID, and 43% genotype DD. ACTN3 (rs1815739) polymorphism was determined as 24% genotype RR, 43% genotype RX, and 33% genotype XX. PPARA (rs4253778) polymorphism was observed as 71% genotype GG, 14.5% genotype GC, 14.5% genotype CC. HIF1A (rs11549465) polymorphism was found to be 67% genotype CC, 33% genotype CT. Concerning physical tests, the evaluation of flexibility test results among genotype groups did not yield significant differences (p=0.365). No significant difference was found among genotype groups with respect to leg strength test results (p=0.691). The evaluation of handgrip strength test results among genotype groups did not reveal significant differences (p=0.679). No significant differences were found among genotype groups when VO2 max test results were examined (p=0.686). A significant relationship was found in the speed test and HIF1A rs11549465 polymorphism evaluation (p = 0.008). No significant results were detected when comparing the speed test with other polymorphisms (p = 0.65). The results of our study support the previous studies which had focused on the potential relation between the relevant gene polymorphisms and athletic performance of ice hockey players. However, doing further studies with larger cohorts is recommended in order to understand the relationship between the relevant polymorphisms and athletic performance of ice hockey players.

Background/Objectives: This study aimed to examine whether rumination statistically accounts for the indirect association between mindfulness and burnout among athletes using a quantitative, cross-sectional, and non-interventional research design. Methods: The sample consisted of 484 licensed athletes (157 females, 32.4%; 327 males, 67.6%) actively involved in team sports, individual sports, and e-sports in Istanbul during the 2024–2025 period. Data were collected using the Athlete Mindfulness Questionnaire, the Sport Competition Rumination Scale, and the Athlete Burnout Questionnaire. Statistical analyses were conducted using IBM SPSS 25 and Hayes’ PROCESS Macro (Model 4), and mediation effects were tested using a bootstrap procedure with 5000 resamples and 95% confidence intervals. Results: The findings revealed significant relationships among mindfulness, rumination, and burnout. Mindfulness was positively associated with rumination, and rumination was significantly associated with athlete burnout. Furthermore, when rumination was included in the model, the direct relationship between mindfulness and burnout became non-significant. Given the cross-sectional nature of the study, the findings should be interpreted as relational rather than causal. Conclusions: In conclusion, the findings suggest that the relationship between mindfulness and burnout may be indirectly shaped through ruminative cognitive processes depending on contextual and cognitive-regulatory factors. The results further suggest that the associations between mindfulness, rumination, and burnout may vary according to competitive context and individual cognitive processing patterns.

Sporun çocuğun sosyal, duygusal, motorsal ve psiko-sosyal gelişimi üzerinde çok önemli bir yeri vardır. Çocukların günlük yaşamında sosyal becerilerinin düzenli olarak katılım sağladıkları sportif faaliyetlerle nasıl etkilendiğini belirlemek çalışmanın amacını oluşturmatadır. Çalışmanın evrenini 2018-2019 eğitim öğretim yılında, özel bir ilköğretim okulunun ortaokul bölümünde okuyan yaşları 9-12 aralığında olan 114 çocuk oluşturmaktadır. Demografik bilgilerin dışında çocuklara sosyal beceri düzeylerini ölçmek için sosyal beceri ölçeği, uygulanmıştır. Verilerin analizinde frekans, t-testi, kruskal-wallis kullanılmıştır. Anlamlılık düzeyi p<0,05 olarak kabul edilmiştir. Çalışma sonucunda öğrencilerin sosyal beceri düzeylerinin x=58,2(±9,11) olduğu belirlenmiştir. Öğrencilerin spor yapma durumlarına göre sosyal beceri düzeylerinde istatistiksel açıdan anlamlı farklılığa rastlanmamasına rağmen spor yapan öğrencilerin sosyal becer düzeyleri daha yüksek bulunmuştur. Ayrıca öğrencilerin sınıf ve cinsiyet değişkenlerine göre sosyal beceri düzeylerinde istatistiksel açıdan anlamlı farklılıklara rastlanmamıştır.

This study aimed to examine the effect of parenting stress levels of physically active and inactive women parents on their communication with their children and to determine whether physical activity status differentiates this relationship. The study employed a cross-sectional design and included 222 women parents aged 25 and over. Data were collected using the Parenting Stress Scale and the Parent–Child Communication Scale. Independent samples t-tests, one-way ANOVA, and Pearson correlation analyses were conducted. The results indicated no statistically significant differences between physically active and inactive women parents in terms of parenting stress or parent–child communication scores (p > .05). Similarly, exercise frequency and age groups did not yield significant differences. However, working mothers scored significantly higher in problem-solving and sensitivity subdimensions compared to non-working mothers (p < .05). Correlation analyses revealed significant negative relationships between parenting stress and parent–child communication in both groups, with stronger associations observed among physically active women. These findings suggest that although physical activity does not directly differentiate stress or communication levels, it may function as a contextual factor influencing the relationship between parenting stress and communication quality.

90–95% of vitamin D which has the supreme function of regulating many metabolisms in tissues and organs, is taken from the sunlight through skin. Since wrestling is performed in sun-protected sports halls, we think that a vitamin D replacement will improve the performance of wrestlers, especially as the limited exposure to sunlight is compared to outdoor sports branches. The aim of our study is to increase the strength and endurance of male wrestlers by applying 25-Hydroxy vitamin D replacement together with general and wrestling-specific trainings for 8 weeks. 36 wrestlers participated in the study and were divided into two groups as subject and control groups. Group A (n: 18) was the exercise-subject group with a 25-hydroxy vitamin D replacement and group B (n: 18) was the exercise-control group without the vitamin D replacement applied. In the subject group, Devit-3 oral ampoule 1 ml (300,000 I.U.) replacement was applied to the wrestlers whose 25-hydroxy vitamin D levels were below 20 ng/mL. Wrestlers were pre-tested one week before the replacement. After 8 weeks, they were post-tested and their vitamin D levels were measured again. Wrestlers in the control group were tested at the beginning and end of the 8-week training program without the vitamin D supplementation. In the analysis of the data, a Wilcoxon test and Mann Whitney test (one of the nonparametric tests) was used in accordance with the distribution width when the averages of the groups were evaluated in terms of significance with each other. The values that were p < 0.05 as the significance level of the data were accepted as statistically significant and the evaluations were made accordingly. When the results of the analysis were examined, it was seen that 25-hydroxy vitamin D levels of the wrestlers increased from 13.85 ng/ml to 26.28 ng/ml after the replacement applied to the wrestlers in the subject group. It was observed that while vitamin D levels of the group increased, their aerobic endurance decreased to 132.22 ± 9.69 from 150.33 ± 20.98 (p < 0.05). Thus, their aerobic endurance improved statistically significant. No statistically significant value was obtained in the test analysis of the wrestlers in the control group. The analysis results obtained from the study showed that the 25-hydroxy vitamin D levels in athletes increased and their aerobic capacity also increased after vitamin D induction. It is possible to say that vitamin supplementation together with 8 weeks training program is more effective for athletes to improve their strength and endurance.
