Background: the purpose of this study was to explore the effect of 10 weeks of yoga intervention on the mental health outcomes (stress, anxiety, and depression), quality of life, emotional regulation, and quality of sleep of medical students. Method: In the current experimental study, 220 medical students, with a mean age of 21.36 ± 2.20 years, participated in a 10-week yoga intervention at the University of Pécs. Data were collected before and after the intervention using the validated questionnaires DASS-21, WHOQOL-BREF, PSQI, and DERS. The distribution of data was checked using the Kolmogorov–Smirnov test. A paired sample T-test was used to compare the mean of the continuous variable. Stepwise linear regression was used to assess the association between mental health outcomes and quality-of-life variables. Results: The present study shows a significant reduction in (p < 0.001), depression (p < 0.001), and anxiety (p < 0.001) for participants, and overall quality of life (p < 0.001), quality of sleep (p < 0.001), and emotional regulation (p < 0.001) significantly improved after the intervention. The stepwise linear regression shows a strong association between higher levels of anxiety (β = 0.608, R2 = 0.366) and depression (β = 0.608, R2 = 0.392), with higher stress levels and improvement in environmental conditions being associated with a decrease in stress levels (β = −0.392, R2 = 0.087). Conclusions: the current study shows that yoga significantly improved the mental health and well-being of medical students, improving quality of life, quality of sleep, and emotional regulation. Registered Clinical Trial: NCT06661603.

Promoting autonomy-supportive teachers’ behaviour is important for teaching students to take responsibility for their performance and for increasing their level of enjoyment in physical education (PE). Based on self-determination theory, our research aimed to identify the antecedents of PE teachers’ motivational strategies that can facilitate students’ psychological needs satisfaction and positive outcomes during PE classes. A total of 376 primary and secondary school PE teachers completed our cross-sectional-design questionnaires in four Central European countries (Hungary, Romania, Slovakia, and Serbia). Measures included perceived job pressures, opportunities for professional development, perceptions of students’ self-determination in PE, teachers’ psychological need satisfaction in their job, teachers’ self-determination at work, and teachers’ provision of autonomy support, structure, and involvement strategies. Jamovi software for structural equation modelling and the path analysis method was used for statistical analysis. Following post hoc modification, the hypothesized model showed a good fit to our model (χ 2 (17) = 64.60, p = 0.00; CMIN/ df = 3.80; CFI = 0.92; TLI = 0.81; SRMR = 0.05; RMSEA = 0.08). Results indicated that teachers’ opportunities for professional development had a significant positive relationship with their need satisfaction at work, which was positively linked with their motivation to teach. Job pressure was negatively associated with basic psychological need satisfaction. Teachers’ perception of students’ autonomous motivation was positively linked with their own autonomous and controlled motivation, and was also directly and positively linked to their use of involvement and autonomy-supportive teaching strategies.

Background: disordered eating (DE) and eating disorders (ED) can negatively impact athletes’ health, wellbeing, and athletic performance. Objective: this cross-sectional study aims to assess DE risk, body composition, and nutrition knowledge among elite Hungarian athletes. Methods: DE risk was assessed using DESA-6H and EAT-26 scales, nutrition knowledge through the Abridged Nutrition for Sport Knowledge Questionnaire (A-NSKQ), and body composition with the OMRON BF511 device. The data were analyzed using Kendall’s tau correlations, Mann–Whitney U tests, and ROC analysis. Results: a total of 71 athletes participated (39.4% males, mean age = 24.8 years, SD = 4.8 years and 60.6% females, mean age = 24.3 years, SD = 4.3 years). At-risk scores on the DESA-6H scale were recorded for nine athletes (12.7%), while 32.4% scored in the risk zone on the EAT-26, with female athletes in aesthetic, endurance and weight-dependent sports being most affected. Low BF was observed in four males and four females. Nutrition knowledge (49.1%) was below the acceptable threshold. DESA-6H significantly correlated with EAT-26 scores, BMI, sports nutrition knowledge, and A-NSKQ total scores. A statistically significant difference by gender was found in the EAT-26 total score (p = 0.019, d = 0.65). Risk groups significantly differed in A-NSKQ scores (p = 0.026, d = 0.511) and sport nutrition knowledge, specifically (p = 0.016, d = 0.491). Using EAT-26 to identify at-risk athletes and the DESA-6H recommended cut-off, the ROC analysis showed a sensitivity of 29.1% and a specificity of 95.7%. Conclusions: insufficient nutrition knowledge plays a role in being at-risk for DE and ED. These results underscore the need for early detection, early sport nutrition education across all elite athletes, with particular attention to female athletes in aesthetic, endurance and weight-dependent sports, and for monitoring these athletes to prevent DE. Further work is warranted to optimize screening tools such as EAT-26 and DESA-6H for elite athletes.

Yoga is increasingly practiced worldwide and is associated with diverse physical and mental health benefits, yet its spiritual dimensions remain underexplored in empirical research. This study investigated the relationship between the weekly frequency of practicing specific yoga components and levels of spiritual well-being and subjective well-being (SuWB). A total of 335 Hungarian adults (mean age = 47.2 ± 10.5 years) with an average of 10.2 ± 7.9 years of yoga experience completed a national online survey. Spiritual well-being (SpWB) was measured using the Spiritual Health and Life-Orientation Measure (SHALOM), and SuWB was assessed with the WHO-5 Well-Being Index. Statistical analyses included ANCOVA, Kruskal–Wallis H tests with post hoc Mann–Whitney U tests, and Kendall’s tau correlations. All four yoga components (āsanas, prāṇāyāma, relaxation, meditation) showed medium-sized positive main effects on SpWB (p < 0.001; η2 = 0.06–0.09) and small but significant effects on SuWB (p = 0.003–0.05; η2 = 0.03–0.04). The strongest effects were observed in the Personal and Transcendental dimensions of spirituality. Weak to moderate positive correlations were found between SuWB and the four SHALOM factors as well as the total SHALOM score. These findings indicate that regular engagement in diverse yoga practices is associated with higher levels of both spiritual connection and mental well-being, highlighting that yoga practice is associated with higher levels of spiritual connection and mental well-being, and may be relevant for mental health promotion.

One of the most prominent topics in contemporary research is how individuals can adopt behaviors and attitudes that support successful aging (SA) throughout their life course. Participation in sport is widely regarded as an important behavioral strategy that contributes to physical, psychological, and social resources relevant to SA. This study examined the association between Tennis Involvement (TI) and orientations toward successful aging in a sample of 224 masters tennis players with a mean age of approximately 51 years. Data was collected using the Tennis Involvement Scale and the Successful Aging Scale, which was applied to assess strategies and predispositions related to successful aging rather than aging outcomes. A structural model was tested using descriptive statistics, reliability analysis, correlation analysis, Confirmatory Factor Analysis (CFA), and Structural Equation Modeling (SEM). The hypotheses assumed that all factors of tennis involvement would be positively correlated with SA, “tackling problems-TP”, and “healthy lifestyle-HL”. However, the SEM analysis results provided partial support for hypotheses H1a and H1c. Only the “social bonding” factor showed a significant and positive correlation. Remarkably, however, the “centrality” factor showed a negative trend, contrary to expectations, and statistically significant correlations were found. No significant correlations were identified between age, TI, and SA. However, there were positive and significant correlations between players’ weekly tennis playing time (both in days and hours) and SA, TP, and HL. In conclusion, the results indicate that, among middle-aged masters tennis players, tennis involvement is associated with both positive and negative aspects of successful aging, and longer tennis playing duration is associated with more favorable successful aging strategies.

Research has rarely explored yoga's link to spirituality, and none have examined spiritual well-being via Fisher's four-domain model. Comparative studies with active control groups are also lacking. This study examines the relationships between spirituality, subjective well-being (SWB), and mental health indicators (depression, anxiety, and stress) among yoga practitioners, physically active individuals, and inactive controls. A total of 1.167 Hungarian adults (79 % females), mean age 34.52 years (SD ± 14.97), completed an online survey assessing spiritual health attitudes and behaviors, SWB, and mental health symptoms, along with the frequency of physical activity. Multivariate analyses showed significant group differences (Wilks' Λ =.811, F(26, 2304) = 9.77, p < .001, partial η² = .099) across the combined dependent variables. Yoga practitioners reported significantly (p < .001) higher well-being and spirituality, and lower depression, anxiety, and distress than both regular exercisers and inactive participants. Regular exercisers also demonstrated more favorable psychological outcomes than inactive individuals, though to a lesser extent than yoga practitioners. Weekly physical activity frequency was positively associated with well-being and negatively associated with mental health symptoms across groups. Correlation patterns revealed several spirituality-related variables that were uniquely and more strongly associated (p < .001 to p < .023) with health indicators in the yoga group. These findings support the mental health benefits of regular physical activity and emphasize yoga's distinct contribution to spiritual well-being. The results highlight the integrative value of embodied spiritual practices, such as yoga, in promoting psychological resilience and holistic well-being.
