Background/objective Psychological well-being disorders are increasingly prevalent among young people. While physical activity is known to benefit psychological well-being, the mechanisms-particularly the role of physical self-perception and gender in recreational context remain underexplored. Grounded in the Conservation of Resources (COR) Theory, this study investigates the mediating role of physical self-perception in the relationship between recreational physical activity and psychological well-being and examines whether gender moderates this mediation among youth aged 15-24.Methods A descriptive-relational survey design was employed. The sample comprised 468 young adults (58.5% male, 41.5% female; M_age = 20.08) who regularly participated in recreational physical activities. Data were collected using the International Physical Activity Questionnaire-Short Form (IPAQ-SF), the Physical Self-Perception Profile (PSPP), and the Warwick-Edinburgh Mental Well-being Scale (WEMWBS). Mediation and moderation analyses were conducted using PROCESS macro-Models 4 and 7.Results The direct effect of physical activity on psychological well-being was not significant. However, physical self-perception fully mediated the relationship between physical activity and psychological well-being (indirect effect: beta = 0.219, 95% CI [0.151, 0.290]). Among the sub-dimensions of physical self-perception, body attractiveness had the strongest mediating effect. Moderation analysis revealed that gender did not significantly moderate the mediation pathways (a path: p = 0.156; b path: p = 0.954). The mediation mechanism operated with similar strength in both males and females.Conclusion Recreational physical activity improves psychological well-being entirely through the enhancement of physical self-perception, supporting the COR theory that physical activity acts as a resource investment. This mechanism is universal across genders in recreational settings. Interventions aiming to improve youth psychological well-being should not only promote physical activity but specifically focus on fostering positive physical self-perception and body image in inclusive, non-judgmental environments.

Koçak, Tevfik; Arpa Zemzemoglu, Tuba Eda; Türkkan, Tugba; Bülbül, Kenan; Yilmaz, Birsen
Orthorexia has recently gained attention as a two-dimensional construct centered on a shared health orientation. Recent conceptual developments distinguish healthy orthorexia (HeOr), defined as a non-pathological interest in healthy eating, from orthorexia nervosa (OrNe), characterized by rigid and compulsive food control accompanied by psychological and social impairment. This cross-sectional study investigated the associations of HeOr and OrNe with sociodemographic variables, dietary behaviors, and obesogenic environmental factors, and aimed to identify shared and distinct determinants of these tendencies with 1,015 adults aged 18-65 years. Orthorexia tendencies were assessed using the Teruel Orthorexia Scale. Additional measures included the Sustainable and Healthy Eating Behaviors Scale, Short Screening Questionnaire of Highly Processed Food Consumption, Adult Food Security Survey Module, Food Label Reading Attitude Scale, Food Choice Questionnaire, and the Obesogenic Environment Assessment Scale. In the adjusted regression models, HeOr was positively associated with sustainable and healthy eating behaviors (beta = 0.26), AFSS food-insecurity severity score (beta = 0.11), food label reading attitudes (beta = 0.07), health-related food choice motives (beta = 0.09), natural-ingredient preference (beta = 0.14), weight-control motives (beta = 0.15), ethical food choice motives (beta = 0.10), and obesogenic social determinants and effects (beta = 0.09). Conversely, affordability-related motives (beta = -0.08), emotional appeal (beta = -0.15), familiarity (beta = -0.10), and obesogenic cultural determinants/access to experts (beta = -0.12) were negatively associated with HeOr. For OrNe, positive associations were observed with sustainable and healthy eating behaviors (beta = 0.13), AFSS food-insecurity severity score (beta = 0.17), mood-related food choice motives (beta = 0.13), weight-control motives (beta = 0.26), familiarity (beta = 0.09), ethical food choice motives (beta = 0.18), and obesogenic social determinants and effects (beta = 0.30), whereas health-related food choice motives (beta = -0.12), affordability-related motives (beta = -0.08), and emotional appeal (beta = -0.24) showed negative associations. These findings suggest that orthorectic tendencies are associated with individual health motivations as well as broader behavioral and environmental contexts; however, because of the cross-sectional design, these associations should be interpreted as correlational and hypothesis-generating rather than causal.

Tutal, Varol; Demir, Okan; Sahin, Oktay; Albayrak, Ahmet Yilmaz; Bayansalduz, Mehmet; Uzun, Recep Nur; Öz, Faik; Sahinler, Yunus; Ceylan, Levent; Yilmaz, Coskun
Background Self-control, self-defense self-efficacy, and mental resilience are fundamental psychological determinants of performance and competitive endurance in combat sports. However, scientific evidence on structured, evidence-based psychological intervention programs for professional female wrestlers remains limited. This study examined the effects of a psychological skills training (PST)-based intervention on self-control, self-defense self-efficacy, and mental resilience in professional female wrestlers. Methods A randomized controlled pre-test-post-test design was employed. Thirty-six professional female wrestlers (aged 18-25) were randomly assigned to a PST group (n = 18) or a control group (CG; n = 18). The PST group completed an 8-week structured psychological intervention alongside regular training, while the CG continued routine training only. Self-control, self-defense self-efficacy, and mental resilience were assessed pre-and post-intervention using valid and reliable psychometric scales. Data were analyzed via repeated-measures ANOVA, with effect sizes calculated. Results Significant group & times; time interactions were observed across multiple outcomes. A highly significant interaction emerged for perceived physical self-defense capacity (SP; F(1,34) = 56.525, p < 0.001, eta p(2) = 0.624) and for DP scores (F (1,34) = 9.360, p = 0.004, eta p(2) = 0.216). Among self-control subscales, significant interactions were found for inhibition (F (1,34) = 8.172, p = 0.007, eta p(2) = 0.194) and, more strongly, for initiation (F (1,34) = 14.157, p < 0.001, eta p(2) = 0.294). For mental resilience, highly significant interactions were detected for confidence (F (1,34) = 59.976, p < 0.001, eta p(2) = 0.638), control (F (1,34) = 32.486, p < 0.001, eta p(2) = 0.489), and persistence (F (1,34) = 32.709, p < 0.001, eta p(2) = 0.490). Overall, the intervention demonstrated medium-to-high effect sizes across psychological performance indicators. Conclusion These findings suggest that PST may serve as a useful complementary approach for enhancing self-control, perceived physical self-defense capacity, and mental toughness in professional female wrestlers. However, results should not be interpreted as evidence of improved competitive wrestling performance, technical success, or objectively measured physical self-defense ability, as these outcomes were not directly assessed in this study.

Broccoli juice is highly nutritious, containing phenolic compounds, chlorophyll derivatives, antioxidants, and other biologically active phytochemicals; however, conventional thermal processing may reduce their stability and bioaccessibility. The aim of this study was to analyse the impact of thermosonication on the following properties of broccoli juice: bioactivity, antioxidant capacity, phenolic profile and in vitro bioaccessibility. Thermosonication conditions were optimized using Response Surface Methodology (RSM) integrated with the Gray Wolf Optimizer (GWO) and Particle Swarm Optimization (PSO) algorithms. Broccoli juice samples were subjected to conventional pasteurization and thermosonication under different processing conditions, and total chlorophyll, ascorbic acid (AA), ferric reducing antioxidant power (FRAP), total phenolic content (TPC), and individual phenolic compounds were evaluated. Digestive stability and post-digestion bioaccessibility were also assessed using a standardized in vitro gastrointestinal digestion model. The developed quadratic models exhibited high statistical significance for TPC and FRAP responses (p < 0.001), with coefficients of determination (R2) of 0.9949 and 0.9853, respectively. The optimum thermosonication conditions were identified as 40 degrees C, 6.75 min, and 64.04% amplitude, under which experimentally validated FRAP and TPC values reached 12.86 mmol TE/L and 149.77 mg GAE/100 ml, respectively. HPLC-DAD analysis showed that gallic acid and naringin were the pre-dominant phenolic compounds, and that thermosonication promoted greater phenolic retention than conventional pasteurization. In vitro digestion results demonstrated that thermosonicated broccoli juice maintained significantly higher levels of TPC, FRAP, chlorophyll, and AA throughout gastrointestinal digestion, with higher TPC recovery (30.45%) than pasteurized samples (26.22%), indicating improved post-digestion bioaccessibility of phenolic compounds. Similar improvements were observed for antioxidant capacity and chlorophyll retention. Furthermore, PSO and GWO optimization results showed strong agreement with RSM predictions, confirming the robustness of the proposed optimization strategy. Overall, thermosonication was shown to effectively and sustainably enhance the functional quality, antioxidant properties, phenolic stability, and digestive bioaccessibility of broccoli juice.
- MakaleAçık Erişim2025Analyzing the impact of economic growth and FDI on sustainable development goals in China: insights from ecological footprints and load capacity factors

This study investigates the impact of economic growth and foreign direct investment (FDI) on China's sustainable development goals (SDGs), specifically Zero Hunger (SDG 2), Life Below Water (SDG 14), and Life on Land (SDG 15). It examines ecological footprints and load capacity factors (LCFs) in cropland, fishing, forest, and grazing land using Fourier bootstrap autoregressive distributed lag (ARDL) cointegration analysis and fully modified ordinary least squares (FMOLS) estimators. The study covers the period from 1979 to 2022. Key findings reveal that while GDP and FDI often exacerbate environmental degradation, urbanization and value-added agriculture, forestry, and fishing (FAFGDP) improve sustainability in some areas. The study confirms the pollution haven hypothesis for most models, suggesting that China's legal and regulatory frameworks may inadequately mitigate FDI's adverse environmental effects. The Environmental Kuznets Curve (EKC) hypothesis is not supported as GDP growth generally increases ecological footprints. However, trade openness and urbanization show positive influences on environmental sustainability. Policy recommendations include enhancing energy efficiency, promoting renewable energy, implementing green technologies in agriculture and urban development, and revising FDI policies to incentivize environmentally friendly practices. These strategies are crucial for achieving China's sustainable development goals and mitigating the pressures of human activities on natural resources.

Güler, Iskender; Yilmaz, Coskun; Soylu, Hakan Hueseyin; Birinci, Muersit Ceyhun; Arslan, Ayla; Ocak, Hakan; Çayir, Huseyin; Kavuran, Korhan; Saç, Ajlan; Uçar, Mine Akkus
Background: The effect of inspiratory muscle training on diaphragm muscle thickness (DT) and one repetition maximal (1RM) in professional natural bodybuilders is still unclear. The aim of the study was to investigate the effect of inspiratory muscle training on diaphragm muscle thickness and 1RM in professional natural bodybuilders. Methods: The study comprised a total of 22 athletes who participated in bodybuilding competitions. Each athlete had undergone a minimum of 5 years of training, with a minimum weekly commitment of 5 hours. Participants were randomly divided into two groups: inspiratory muscle training (IMT) and control (CON). The CON continued their normal training regime, while the IMT group also performed inspiratory muscle training with a 10% weekly increase by setting the resistance setting of the PowerBreathe (R) Classic device to 40% of the participant's maximum inspiratory pressure (MIP). Prior to and during the 4-week training period, 1RM bench press measurements and diaphragm muscle thickness measurements were obtained. Results: In the comparison of 1RM power values before and after training, it was determined that the IMT group (%: 11.20) had 6.3% more post-activation performance enhancement compared to the CON group (%: 4.9) (p < 0.001). In the study, it was determined that a higher level of significant post-activation performance enhancement was obtained in the IMT group compared to the CON group in the diaphragm muscle thickness inspiratory phase (DT ins) and ekspiratory phase (DT eks) parameters at 20.36% and 19.46%, respectively. Conclusion: In conclusion, we determined that the addition of progressive loading inspiratory muscle training to preparation programmes in natural bodybuilders will improve diaphragm muscle thickness, 1RM physical performance. In particular, it shows that the diaphragm muscle should be considered not only as a muscle that supports respiration, but also as a muscle that contributes to power generation by optimising intra-abdominal pressure.

Background: The extant research on judo sports has principally concentrated on the physiological effects of training. Conversely, there has been limited attention paid to studies on psychological resilience, self-control, and emotional expression levels. The present study examined the effects of Judo exercises on psychological resilience, self-control, and emotional expression levels in healthy male subjects. Methods: The present study comprised 50 healthy, sedentary male subjects. The subjects were randomly divided into two groups: one group participated in judo training (JT) and the other group served as the control group (CON). The sample sizes for the JT and CON groups were both 25. The JT group underwent judo training, while the CON group maintained their usual lifestyle. The Brief Psychological Resilience Scale, the Multidimensional Brief Self-Control Scale, and the Berkeley Emotion Expression Scale were administered prior to and following the 6-week training period. Results: The study demonstrated that a 6-week judo training regimen exerted a significant effect on the psychological resilience score (e.s. = 1.047, p < 0.001), while no such effect was observed in the Control group (e.s. = 0.0091, p = 0.751). In the context of self-control levels, an effect was observed on the Initiation sub-dimension (e.s. = 1, 739, p < 0.001), yet no effect was found on the Inhibition dimension (e.s. = 0.052, p = 0.892). In the control group, a significant decrease was identified in the Initiation sub-dimension (e.s. = 0, 785, p = 0.001) and Inhibition sub-dimension (e.s. = 1, 861, p < 0.001). The findings indicate that impulse power (e.s. = 0.395) and concealment (e.s. = 0.428) exerted a negligible influence on the emotional expression sub-dimensions. Conversely, psychological resilience (e.s. = 0.886) demonstrated a substantial impact. Conclusions: The judo exercises demonstrated a favorable impact on psychological resilience, self-control, and emotional expression levels in healthy male subjects. The findings of this study may offer significant insights into the impact of judo exercises on psychological resilience, self-control, and emotion expression levels. These findings could serve as a guide for the development of future interventions and program design in the domain of sport psychology.

Introduction: This study examined the associations among ruminative thinking style (RTS), subjective wellbeing (SWB), and cognitive-behavioral physical activity (CBPA) in a sample of 1,326 adolescents (aged 14-18) from sports high schools. Method: Using validated self-report measures, data were analyzed through bootstrapped mediation models. Results: RTS was negatively associated with SWB (beta = -0.1792, p < 0.001), while CBPA showed a partial mediating effect in this relationship (indirect beta = 0.0779, p < 0.001). Discussion: These results suggest that cognitive-behavioral orientations toward physical activity may buffer the negative impact of rumination on wellbeing. Consistent with cognitive-behavioral therapy (CBT) principles, CBPA could provide adolescents with self-regulatory strategies that support mental health. However, the cross-sectional and self-report design, as well as the focus on sports high school students, limit causal inference and generalizability. Future longitudinal and cross-cultural studies are needed to confirm these findings. Overall, the study provides preliminary evidence that CBPA-informed approaches may hold promise for promoting adolescents' mental wellbeing.

Background A limited number of studies have investigated the effects of circadian rhythm-based running exercise interventions on physical fitness in child athletes. This study aimed to investigate the effects of an eight-week morning and evening running program on lower extremity strength, agility and respiratory function in 10-12-year-old male footballers.Methods Participants visited the laboratory three times, with one-day intervals before and after the training program. The assessments included maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and the FEV1/FVC ratio. Additionally, agility and functional performance tests (FPTs) were conducted for both the dominant and non-dominant legs.Results The findings indicated that morning running was more effective than evening running in enhancing respiratory function. Morning running also showed superior results in lower extremity strength tests, particularly in the single-leg (SL) and triple-leg (THD) crossover hop for distance tests (CHDs) and the 6-m timed-hop test (6 m THT). Furthermore, the agility performance of the morning running group was significantly better than that of the evening and control groups.Conclusion Consequently, morning running interventions had a positive impact on key physical fitness parameters, including respiratory muscle strength, respiratory function, agility, and lower extremity strength in child footballers.

Background: The extant research on Taekwondo has focused primarily on the physiological effects of training, with limited interest in psychological resilience, self-defence and quality of life levels. The present study examined the effects of Taekwondo exercises on psychological resilience, self-defence and quality of life levels in healthy female subjects. Methods: The present study comprised 30 healthy, sedentary female subjects. The subjects were randomly divided into two groups: one group participated in Taekwondo training (TG), while the other group served as the control group (CG). The sample sizes for both the TG and CG groups were 15. The TT group underwent conventional Taekwondo instruction, while the CG group maintained their habitual routine and refrained from sporting pursuits. The Brief Psychological Resilience Scale, the Physical Self-Defence Scale for Women, and the SF-12 Quality of Life Scale were administered before and after the six-week training period. Results: The 6-week Taekwondo training programme led to significant improvements in both physical health (PH) (p = 0.049) and mental health (MH) (p < 0.01) scores in female participants. It did not produce a significant change in psychological resilience (PR) scores (p > 0.05). It produced significant improvements in self-defence against simple physical attacks (SP) (p = 0.004) and self-defence against dangerous physical attacks (DP) (p = 0.041) scores. Conclusion: The positive effects of Taekwondo training on psychological resilience, physical self-defence and quality of life levels have been demonstrated in healthy female subjects. This study provides valuable insights into the impact of Taekwondo exercises on psychological resilience, physical self-defence and quality of life levels. The findings of this study can guide future intervention and programme design in the context of sports psychology.

Background: The impact of resistance training extends beyond the enhancement of muscle strength, encompassing improvements in physical performance, postural stability, and overall functional capacity. This study aimed to investigate the effects of a 4-week resistance training program on functional capacity, respiratory muscle strength, diaphragm thickness, and liver density in healthy older women. Methods: The study included 30 healthy women aged 60-80 years and was designed as a randomized controlled experimental trial. Participants were randomly assigned to a resistance training (RT) group or a control (CON) group. Each participant attended the laboratory on three occasions: during the initial visit, the study procedures were explained; the second visit involved baseline assessments (6MWT, diaphragm thickness and liver fat via ultrasound, and respiratory muscle strength); and final measurements were conducted after the 4-week training programme during the third visit. Results: When pre- and post-training measurements were compared, the resistance training (RT) group demonstrated a significantly greater improvement (8.02%) in the Six-Minute Walk Test (6MWT) distance compared to the control group (p < 0.001). In terms of diaphragm thickness (DT), the RT group showed a 16.66% increase, whereas the control group exhibited a 1.13% decrease (p < 0.001). Maximal inspiratory pressure (MIP) increased by 12.30% in the RT group, while it decreased by 7.25% in the control group, indicating a 19.55% greater improvement in the RT group (p < 0.001). Regarding maximal expiratory pressure (MEP), a significant improvement of 21.48% was observed in the RT group, whereas a 0.75% decrease was recorded in the control group, resulting in a 22.23% greater enhancement in the RT group (p < 0.001). Finally, liver density (LD) increased by 12.30% in the RT group, while it decreased by 7.25% in the control group (p < 0.001). Conclusion: As a result of resistance training, greater improvement was observed in functional capacity, respiratory muscle strength, diaphragm thickness and liver density in the training group compared to the control group.

Background The existing research on Muay Thai sports has focused predominantly on the physiological effects of training, with limited attention devoted to the study of quality of life, love of life and self-control. The present study examined the effects of Muay Thai exercises on quality of life, love of life and self-control scores in healthy male subjects. Methods The present study comprised 50 healthy sedentary male subjects. The subjects were randomly divided into two groups: one group engaged in Muay Thai training (MTT), while the other group served as a control group (CON). The sample sizes for the MTT and CON groups were both 25. The MTT group participated in basic Muay Thai training, while the CON group continued their normal life regime. The SF-12 quality of life scale, love of life scale and multidimensional self-control scale were administered before and after the six-week training period. Results The study concluded that the six-week Muay Thai training program had a significant effect on quality of life levels, with 13.23% (p = 0.003) and 21.93% (p < 0.001) of participants demonstrating improvements in physical and mental scores, respectively. In terms of self-control levels, the program was found to have a significant effect on initiation and inhibition scores, with increases of 23.78% (p = 0.001) and 24.69% (p < 0.001), respectively. It was concluded that had a significant effect on the sub-dimensions of the Love of Life scale with increases of Positive Attitude Toward Life (PAWL) 18.63% (p < 0.001), Happy Results of the Love of Life (HRLL) 20.11% (p < 0.001) and Meaningfulness of Life (ML) 15.62% (p < 0.001), respectively. However, no significant differences were detected in any of the scales within the control group. Conclusion Muay Thai exercises had a positive effect on quality of life, love of life and self-control levels in healthy male subjects. By providing valuable insights into how Muay Thai exercise affects quality of life, love of life, and self-control, this research can guide future intervention and program design in the context of sport psychology.

Ozbilgin, Mustafa F.; Erbil, Cihat; Demirbag, Orkun; Gündogdu, Nur; Demirbag, Kuebra Simsek
Introduction Drawing on Durkheim's historical theorization of suicide, we extend his concept of anomic suicide, which is suicide due to a lack of social regulation, to introduce the concept of institutional suicide. We define institutional suicide as suicide due to the absence or decline of institutional policies, practices, and discourses for prevention. In this study, we explore the mechanisms for institutional suicides based on suicide notes Turkey, in a context without institutional responsibilization for prevention. Turkey provides a significant context for studying institutional suicides as policies, practices, and discourses for suicide prevention have been declining for some decades.Methods Drawing on publically available suicide notes and narratives in Turkish media outlets, we analyze 17 suicide notes and responses from their institutions of work and friends, family, and colleagues.Findings and Discussion We identify two mechanisms that lead to institutional suicides: (1) dehumanization due to lack of recognition and (2) misrecognition through a devaluation of potential. We extend the theory of anomie to institutional settings and offer social policy suggestions to improve institutional responses based on co-design based on suicide notes to prevent institutional suicides and call for institutional responsibilization for preventing work-related suicides.

Background: Since children and adolescents usually spend their theoretical course time at schools, they experience many negative effects of inactivity and physical inactivity. They are disadvantaged in terms of facing many health and social problems due to lack of physical activity. This sedentary life increases their exposure to screens and the time they spend sitting. Aim of the study: The first aim of this research is to conduct an experimental study to reduce the excessive screen time of college students with an exercise intervention. The second aim of the study is to examine the perceived benefits of leisure activities of students with an exercise intervention. Methods: In this direction, the study group of the research, which was conducted as an experimental study, consisted of 176 [74 female (42.0%), 102 male (58.0%)] students studying in the department of mathematics at college. In the study, the screen exposure time of students was measured with the Screen time scale for youth and adolescents along with a personal information form. In addition, the Perceived Leisure Benefit Scale scale was used to evaluate the participants' awareness of the benefits obtained from leisure activities. Results and conclusion: According to the findings of the research, it was determined that there was a positive and significant decrease in the screen time of the experimental group participants of students who participated in the research before and after the exercise intervention. In the Leisure Benefit Scale, it was observed that there were significant positive differences in favor of the experimental group.
- MakaleAçık Erişim2022The cultural practice of decluttering as household work and its potentials for sustainable consumption
Muster, Viola; Iran, Samira; Muensch, Marlene
Popular literature and guidebooks on minimalism and decluttering have brought the idea of less is more into the mainstream. Although decluttering constitutes a central household chore in consumer societies, it is rarely communicated as work within the current popular minimalism discourse, but rather as an expression of self-care. Whether and to what extent this lifestyle minimalism can contribute to sustainable consumption has - with a few exceptions - not yet been studied in detail. In this article, decluttering is first conceptualized in between housework and self-care. Based on this work, potentials and limits for the promotion of sustainable consumption are outlined. Finally, initial insights from an ongoing citizen science project on decluttering in Germany are presented. The qualitative results from two workshops and two reflection exercises show that the main motivation for participants is the dissatisfaction with their multitude of possessions and the desire for fewer material possessions in the future. The decision to declutter can be understood as a window of opportunity in which individuals are willing to reflect on and realign their possessions and desires for goods. Thus, we argue that decluttering can be a relevant starting point for changing consumption behavior toward (more) sustainable consumption. At the same time, it remains unclear whether and to what extent the participants' willingness to change regarding possessions and consumption actually leads to more sustainable consumption behavior after decluttering. It is even conceivable that the newly gained space will stimulate additional consumption. Decluttering would then rather function as a catalyst for further consumption (and would have no or rather a negative contribution to sustainability goals). Further research is needed to shed light on this.

Performance is judged using a variety of methods to ensure uniformity between competitions. Uchikomi Fitness Test (UFT) could accomplished between morning qualifying and evening finals. The purpose of this study is to investigate the impact of different warm-up protocols on UFT at different times of the day in female judokas. Ten volunteer women who had been practising judo on a regular basis for more than 5 years and actively competed in international tournaments took part in this study. Judokas completed UFT, either after no-warm-up (NWU), specific warm-up (SWU), and linear+lateral warm-up (FWU) protocols for two times a day in the morning: 09:00-11:00 and in the evening: 16:00-18:00, on non-consecutive days. In conclusion, there was a significant increase in UFT scores (F = 9.89; p = 0.002), a + b (F = 4.42; p = 0.04) and heart rate (F = 28.99; p < 0.001) in the early evening compared to the morning. Increases in UFT performance were observed in the SWU protocol compared to the NWU and FWU protocols (p < 0.05). However, the interaction between time of day and warm protocol was not significant (p > 0.05). The UFT performance revealed diurnal variation, and the judokas' performances may be favourably affected more in the late hours, particularly following SWU procedures.

Europe's forests provide vital habitat for biodiversity and essential ecosystem services whose provision must be sustained or enhanced over the coming century. However, the potential to secure or increase forest ecosystem services, while securing the habitat requirements of taxa remains unclear, especially within the context of uncertain climate and socio-economic developments. To tease out the associated trade-offs and synergies, we used 10 case study landscapes within nine countries throughout Europe. Starting with the current status of the forests in the case study landscapes, we simulated forest development 100 years into the future. Simulations were embedded in three combined climate and socio-economic frame scenarios based on global and European policies which varied in their climate change mitigation efficiency. Scenarios were translated into country specific projections of climate variables, and resultant demands for wood products. Forest management regimes were projected to vary in response to these scenarios at local scales. The specific combinations of alternative forest management practices were based on parallel research and input from local forest stakeholders. For each case study, a specific forest growth simulator was used. In general, the climate scenarios applied did not cause fundamentally different ecosystem service outputs at the case study level. Our results revealed almost no reduction in outcomes for biodiversity indicators with an increase in wood production, and in some cases synergistic results occurred when diversity was actively promoted as part of the management concept. Net carbon uptake was not strongly correlated with biodiversity, indicating that biodiversity-friendly forest management doesn't need to curtail carbon sequestration. Notably, we obtained heterogeneous results for the relation between sustainable wood production and net carbon uptake. Most scenarios resulted in a more or less reduced net carbon uptake over the long term, often due to stand age class distribution shifts. Levels of sustainable wood production varied widely during the simulation period, from significant increases (Sweden, Lithuania) to minor changes (Slovakia, Turkey) and slight decreases (Ireland, Netherlands). We place our results within the larger context of European forest policy and the challenges of simulating and contrasting forest biodiversity and the ecosystem services that societies depend on.
