Sustained engagement in physical activity during adolescence is a critical determinant of long-term health and well-being. Performance feedback is widely used in youth sport settings, yet its motivational impact may depend on athletes’ developmental stage and training experience. This study examined adolescents’ motivational responses following individualized sprint performance feedback and investigated whether training experience and sprint performance moderated these responses. Fifty-three adolescent athletes (mean age = 14.86 ± 0.81 years) completed a brief five-item questionnaire assessing commitment, enjoyment, self-determination, intention to continue training, and self-efficacy immediately after receiving individualized sprint performance feedback. Exploratory and confirmatory factor analyses were conducted to evaluate the scale’s factorial structure and reliability. A two-way analysis of variance examined the effects of training age (1–6 vs. 7–12 years) and sprint performance (faster vs. slower) on overall motivational response. Factor analyses provided preliminary support for a unidimensional motivational response construct (ω = 0.92; α = 0.92). Overall motivational responses following feedback were moderately positive. Sprint performance demonstrated a significant main effect on motivation. Importantly, a significant interaction between training age and performance emerged as the key finding, indicating that less experienced athletes were more sensitive to performance outcomes, whereas motivation among more experienced athletes remained relatively stable. Individualized sprint performance feedback appears to be associated with moderately positive motivational responses in adolescent athletes, particularly during early stages of sport participation. These findings highlight the importance of developmentally appropriate feedback strategies that emphasize progress and competence development to support engagement in youth sport, which may be relevant for sustained participation over time.

Over the past two decades, the concept of physical literacy (PL) has gained increasing attention across research and policy domains. Grounded in holistic and embodied theoretical frameworks, PL encompasses physical, affective, cognitive, and social dimensions that underpin lifelong engagement in movement. Global policy frameworks, including the World Health Organization’s Global Action Plan on Physical Activity (2018–2030) and UNESCO’s Guidelines for Quality Physical Education, highlight PL as a foundation for health and wellbeing. Despite this recognition, research examining the associations among PL, physical activity (PA), and mental health in Mediterranean contexts remains scarce. This study examined the interrelationships among perceived PL, PA, and MH in a sample of 542 Cypriot children and adolescents aged 6–18 years. Participants completed the Perceived Physical Literacy Instrument (PPLI), the Physical Activity Questionnaire for Older Children (PAQ-C), and the Depression, Anxiety, and Stress Scale (DASS-21). Structural Equation Modelling (SEM) was used to test direct and indirect effects, and multi-group analyses explored measurement and structural invariance across gender and age. Results indicated that higher perceived PL was associated with better MH, both directly and indirectly through increased PA. Boys and younger participants reported higher PA levels, whereas adolescents displayed higher symptoms of depression, anxiety, and stress. However, the structural relationships among PL, PA, and mental health were consistent across genders. The findings highlight the role of PL as a multidimensional determinant of youth wellbeing and underscore the importance of promoting physical literacy aligned behaviours from early childhood within educational and community settings.

Background/Objectives: Insufficient hydration and high consumption of sugar-sweetened beverages (SSBs) is a significant public health challenge among adolescents. The aim of the presented study was to assess the beverage intake, in terms of quantity and choices, in a national-based population of Polish adolescents within the PLACE-19 Study. Methods: Within the PLACE-19 Study, the population of n = 1027 secondary school adolescents (age 15–20 years) was recruited based on a quota sampling of Polish secondary schools and n = 984 individuals (n = 674 female, n = 310 male) were included in the analysis. The study assessed beverages intake using the National Youth Physical Activity and Nutrition Study (NYPANS) survey questionnaire and data were gathered using the Computer-Assisted Web Interview (CAWI) technique. The beverages were assessed in the following groups: water, milk beverages, 100% fruit juices, coffee/tea, regular carbonated soft drinks (CSDs), diet CSDs, other sugar-sweetened beverages (SSBs); additionally, total SSBs were summarized. The total beverage intake was compared with 80% of the Adequate Intake (AI) level. Results: The highest intake was observed for water (250 mL per day), and tea beverages (178.1 mL per day). However, in combining SSBs, the total daily intake for this group was 394.4 mL per day. The highest share of the daily intake of beverages was attributed to water intake (23.81%), and tea beverages (11.45%), followed by 100% fruit juices (7.14%), fruit drinks (6.67%), and milk (6.45%); however, the intake of total combined SSBs was even higher than for water (32.47%). Male individuals were characterized by a higher share of milk beverages, regular CSDs, diet CSDs, and other SSBs than female ones, while female individuals were characterized by a higher share of water, and coffee/tea in their total daily beverage intake than male ones (p < 0.001). Younger individuals were characterized by a higher share of other SSBs in their total daily beverage intake than older ones (p = 0.034). For the vast majority of the studied group, the inadequate intake of beverages was observed, as over 70% of the studied sub-groups did not meet the AI value. Conclusions: The inadequate beverage intake in a population of adolescents may be a problem, especially considering high intake of SSBs, and relatively low intake of water. Especially in male and younger individuals, due to a higher intake of SSBs, than for female and older individuals, education is necessary to promote adequate intake and choices of beverages. Further research is needed in the area of beverage consumption to understand the determinants of beverage consumption and develop opportunities to improve it. Full article

This study aims to provide insights into how physical activity is associated with sleep patterns in youth populations, in particular, Slovak adolescents, and how gender (boys vs. girls) and age (≤16 vs. ≥18) moderate this relationship, using an extreme-group comparison approach that excludes 17-year-olds to enhance contrast between developmental stages. Using a cross-sectional design, self-reported data were collected from 2504 (100%) high school students (aged 15–19; 45.6% boys, 54.4% girls) using the International Physical Activity Questionnaire-Short Form (IPAQ-SF) and the Pittsburgh Sleep Quality Index (PSQI). Participants aged 17 years were excluded from age-stratified analysis to create clearer separation between early/mid and late adolescence. The primary outcome was global sleep quality (PSQI > 5). Secondary outcomes included sleep duration and PSQI component scores. All other analyses (age- and gender-stratified comparisons and interaction models) were predefined as exploratory and hypothesis-generating to examine potential effect modification. Age-stratified analyses among girls showed that, within the low PA group, good sleep was reported by 37.7% of younger girls (≤16) and 28.6% of older girls (≥18). Among older girls, the proportion reporting good sleep increased to 49.8% in the high PA group (χ² = 29.16, p < 0.001). No consistent associations between PA and sleep quality were observed among boys; however, significant association was identified among younger boys (≤16 years), which was not observed in older boys. Logistic regression revealed a modest interaction between age and PA level in predicting sleep quality among girls (β = 0.346, p = 0.049), suggesting small age-dependent variation in the association. This effect should be interpreted cautiously given its borderline statistical significance. Component-level PSQI analyses showed that girls experienced higher rates of sleep disturbances (χ² = 91.40, p < 0.001), longer sleep latency (χ² = 26.71, p < 0.001), and greater daytime dysfunction (χ² = 79.90, p < 0.001). These findings provide region-specific evidence from Central and Eastern Europe and underscore the need for age- and gender-sensitive public health strategies targeting both physical activity promotion and better sleep outcomes, given their observed associations.

Background: Parents are children’s primary role models, are food and physical activity gatekeepers, and create the home structure/lifestyle environment. Thus, parents strongly influence children’s weight-related behaviors and have the opportunity to cultivate a “culture of health” within the home. Methods: The aim of the HomeStyles-2 (also called HomeStyles-Child) RCT was to determine whether this online, novel, age-appropriate, family intervention enabled and motivated the 131 systematically randomly assigned by computer parents of children in middle childhood (ages 6 to 11) in the experimental condition to shape home environments and healthy weight-related lifestyle practices to be more supportive of optimal health and reduced obesity risk in middle childhood youth more than the 134 counterparts assigned to the attention control condition. Results: This RCT demonstrated the feasibility of online delivery of a health promotion intervention to parents of children in middle childhood, which may inform the development of interventions targeting other age groups and health outcomes. Results indicate the HomeStyles-Child intervention improved healthy-weight-related behavior cognitions, which are predictors of behavior change, of the experimental group. Additionally, improvements in experimental parent and child health-related behaviors were observed. These improvements occurred during a time when families faced unprecedented and extraordinary economic and social stresses associated with the COVID-19 pandemic. Conclusions: HomeStyles-Child is one of the few interventions for families with middle childhood youth. It has the potential to help ameliorate obesity in middle childhood youth and, by extension, other family members. Full article

Playing sports remains one of the most common avenues for youth engagement in physical activity. Yet mental health challenges, such as performance anxiety, depressive symptoms, reduced motivation, and burnout, place many young athletes at risk. As key mediators of sport participation, coaches’ roles are often underscored in recognizing shifts in athlete motivation, behavior, or well-being. Gaining better insight into athlete mental health status may enable coaches to provide timely support and strengthen athlete and team well-being. In this study protocol, we employ a mixed-methods design, evaluating the effectiveness of an AI-augmented mobile application (i.e., ThriveNudge) in promoting the mental health of youth athletes. ThriveNudge helps coaches monitor athlete mental health, flag mood disruptions, and practice supportive communication via simulated chats. A target sample of four interscholastic teams (with athletes aged 14–18 years) and their head coaches will be recruited. Teams will be cluster-randomized to either the intervention condition (n = 2), receiving pre-season training to implement ThriveNudge, or to a waitlist control condition (n = 2). Primary outcomes, including athlete burnout, motivation, coach–athlete relationships, and sport enjoyment, will be measured using psychometric scales administered online. Semi-structured interviews will be conducted with coaches and athletes in the experimental group to collect qualitative data on user interface and user experience. We hypothesize that teams using ThriveNudge will report lower athlete anxiety and burnout, higher intrinsic motivation and enjoyment, and stronger coach–athlete relationships than athletes in control teams. We aim to provide a scalable and accessible digital platform that safeguards youth mental health. Full article

Background: Phase angle (PhA), derived from bioelectrical impedance analysis (BIA), is a non-invasive parameter that reflects cellular integrity and nutritional status. Although PhA is increasingly used in pediatric settings, evidence on modifiable determinants in healthy adolescents remains limited. Methods: This study was conducted in 56 adolescents (median age 16 years) who underwent BIA measurement including PhA at 50 kHz. Lifestyle and diet were assessed using the validated questionnaire and included physical activity level (school and free time), sleep length, and diet quality indices together with selected food intake frequencies. Results: The median PhA was 5.16° (IQR 4.88–5.46). In multivariable models, male sex (B = 0.96, p < 0.001) and higher free-time physical activity were independently associated with higher PhA, with graded effects for moderate (B = 0.42, p = 0.004) and high activity (B = 0.55, p = 0.001) versus low. Dietary indices and individual food items did not retain significance after adjustment. Penalized logistic models confirmed lower odds of low PhA with moderate (OR: 0.13, 95% CI: −3.66 to −0.56) and high (OR: 0.01, 95% CI: −9.15 to −1.87) versus low free-time activity. Conclusions: In healthy adolescents, habitual free-time physical activity is the main factor of PhA. These findings support the promotion of physical activity in youth as a modifiable determinant of cellular health. Full article

Background/Objectives: Adolescence represents a critical period for the formation of lifestyle habits that often persist into adulthood, significantly shaping long-term health outcomes and contributing to the development of non-communicable diseases. This study aims to assess the impact of Food Game, a secondary school-based programme, delivered throughout the academic year, to promote healthy eating, physical activity, and sustainability awareness among students. Methods: As part of the Food Game programme, 184 adolescents aged 14–16 years from the Milan area (Italy) completed two questionnaires, administered before and after the intervention (November 2024, April 2025), evaluating dietary habits, lifestyle behaviours, and attitudes toward sustainability. This uncontrolled intervention study assessed dietary changes using a composite score [0–14], with higher scores indicating healthier eating patterns. Pre–post intervention differences were analysed using paired t-tests for continuous variables and McNemar’s test for categorical variables. Results: After participation in Food Game, a significant improvement in mean dietary score from 7.6 to 8.2 (p < 0.001) occurred. Overall, 28.3% of the students worsened their score and 53.2% improved (≥1-point increase), including a significant improvement (≥2-point increase) in 29.4%. Fruit, vegetable, and fish intake increased, while consumption of meat, processed meat, and snacks decreased (p < 0.05). Waste recycling did not change (94.6%), and tap water non-significantly increased. No significant changes were observed in water intake, physical activity, screen time, or addictive behaviours. Conclusions: These findings support the potential of peer-led gamified interventions to promote healthier eating in youth. Future controlled studies are required to rigorously evaluate the Food Game programme’s effectiveness in relation to adolescents’ diet, lifestyle, and sustainability habits. Full article

Background: Among many deleterious effects on the well-being of children and youth, the COVID-19 pandemic contributed to a surge in youth mental health distress. This, coupled with pre-existing prolonged wait times for mental health care, highlighted the need for accessible community-based mental health supports. The Healthy Living Project (HELP) is a virtual lifestyle change support program aimed at promoting positive lifestyle changes and improved mental well-being among youth with mental distress. A pilot feasibility study explored youth engagement with HELP e-resources, and preliminary mental health and lifestyle measures over a 3-month period. Methods: Youth were enrolled in a 3-month pilot of the HELP e-resource. Feasibility metrics (recruitment, retention, and platform engagement) were documented, while exploratory self-reported data on emotional and behavioral difficulties, youth quality of life, sedentary behavior (screen time), sleep hygiene, and physical activity were assessed at baseline and 3 months. Results: Twenty-three youth (mean age 15.7 years, SD 1.7) completed baseline assessments and started the intervention, with ten participants retained by the end of the study. Compared with non-completers (n = 13), study completers (n = 10) tended to report higher quality of life and healthier habits (lower screen time, improved sleep hygiene, and higher activity). Ongoing access to HELP over 3 months was associated with suggestive trends toward improvement in emotional and behavioral difficulties and sleep hygiene. Engaged participants who received screen time education tended to report lower screen times as compared to unengaged counterparts. Conclusions: This study provides early insights into the implementation and acceptability of HELP e-resources among youth experiencing mental distress, with suggestive trends toward potential benefit. Low recruitment and high attrition preclude definitive conclusions, and the findings should be interpreted as exploratory. Lessons from this pilot will inform the design of a subsequent trial to more rigorously evaluate feasibility and the potential impact of HELP on youth with mental distress. Full article

Background: Physical inactivity during adolescence remains a major public health concern, yet its multifactorial determinants are not fully understood in low- and middle-income settings. Objective: To identify and quantify the determinants of physical activity (PA) among Brazilian adolescents using a hierarchical logistic regression model that reflects the theoretical ordering of distal to proximal factors. Methods: A cross-sectional study was conducted with 856 adolescents (13–19 years). Data were obtained from the validated Brazilian Youth Risk Behavior Survey and the Brazilian Economic Classification Criteria (ABEP) socioeconomic questionnaire. PA was dichotomized according to World Health Organization recommendations. Hierarchical logistic regression examined five theoretical blocks: sociodemographic, anthropometric, substance use, weight/diet, and sedentary behavior. Results: Overall, 5 out of 17 predictors were significant in the full model. extended Body mass index (eBMI) was negatively associated with physical activity (OR = 0.331, 95% CI: 0.169–0.647, p = 0.001), while body mass was positively associated (OR = 2.078, 95% CI: 1.045–4.135, p = 0.037). Working status (OR = 1.235, 95% CI: 1.035–1.475, p = 0.019) and weight loss attempts (OR = 1.327, 95% CI: 1.042–1.690, p = 0.022) increased the odds of being active, whereas current smoking reduced it (OR = 0.715, 95% CI: 0.517–0.990, p = 0.043). Model discrimination improved progressively (AUC = 0.577 to 0.692). Conclusions: Physical activity among Brazilian adolescents was primarily influenced by behavioral and perceptual rather than demographic factors. These findings highlight the need for integrated interventions promoting muscle development, body positivity, and smoking prevention. Full article

Background: Body image, physical self-concept and anxiety are closely intertwined aspects of psychological well-being among youth. The growing influence of social media and appearance-focused culture has intensified self-evaluation pressures, making it essential to understand whether physical activity fosters protective effects or, conversely, contributes to anxiety. Methods: The study examined the relationship between body appreciation, physical self-concept, self-esteem, and anxiety among 246 young adults aged 18–35 years (47.6% athletes, 52.4% non-athletes). Participants completed the Rosenberg Self-Esteem Scale (RSES), Body Appreciation Scale-2 (BAS-2), State-Trait Anxiety Inventory (STAI), and the short form of Physical Self-Description Questionnaire (PSDQ-S). Group differences were analyzed using the Mann–Whitney U and Kruskal–Wallis H tests, and associations were explored with Spearman’s correlations. Moderation analyses (PROCESS Model 1) tested whether physical activity buffered BMI-related effects, and structural equation modeling (SEM) evaluated direct and indirect pathways. Results: Athletes reported higher self-esteem and body appreciation and scored higher on all PSDQ-S subscales, alongside lower trait anxiety but higher state anxiety than non-athletes. Higher BMI predicted lower self-esteem, body appreciation, and less favorable self-perceptions. Physical activity moderated the BMI—self-esteem and BMI—body appreciation relationships, buffering negative effects among athletes. SEM showed that physical activity positively influenced physical self-concept and body appreciation, which in turn reduced trait anxiety. Gender differences were minimal. Conclusions: Regular sport participation supports psychological resilience by enhancing self-esteem and body appreciation while reducing anxiety. However, the findings also highlight the complexity of body–mind dynamics where individuals with strong body appreciation may still experience transient anxiety in evaluative contexts. Promoting body functionality, self-compassion, and positive physical self-concept in educational and sport settings may help prevent maladaptive behaviors and foster lasting mental well-being among youth.

Accurate measurement of physical activity is crucial for promoting health and preventing non-communicable diseases, particularly in Sub-Saharan Africa, where the dual burden of infectious and chronic diseases presents significant public health challenges. While self-reported tools are commonly used, they are often limited by recall and social desirability biases. This study aimed to compare self-reported physical activity with objectively measured pedometer data and explore their associations with fitness and anthropometric indicators among university students. A cross-sectional study was conducted among 60 full-time students at a South African university. The study was conducted in two phases: For phase 1, participants completed the International Physical Activity Questionnaire (IPAQ). For phase two, participants wore pedometers for seven consecutive days to measure total and aerobic step counts. Fitness was assessed using the Harvard Step Test to calculate the Physical Efficiency Index (PEI), and anthropometric data (BMI, waist-to-hip ratio, body fat percentage) were recorded. Statistical analyses included Spearman’s correlations, Mann–Whitney U test, Kruskal–Wallis H test, and multivariable linear regression. While 83.3% of participants self-reported high physical activity levels, pedometer data indicated that 61.7% accumulated fewer than 1500 aerobic steps per day and 53.3% recorded fewer than 5000 total steps. No significant association was found between self-reported activity and pedometer-measured steps (p-value = 0.748 and p-value = 0.835, respectively). Objective measures showed significant positive correlations between aerobic steps and PEI (r = 0.274, p-value = 0.034) and significant negative correlations with BMI (r = −0.489, p-value < 0.001) and body fat percentage (r = −0.255, p-value = 0.046). Older age and female gender were associated with lower step counts. This study reveals a significant overestimation of physical activity in self-reports compared to objective measures and stronger links between objectively measured steps and key health outcomes. The findings highlight the need to integrate objective monitoring tools into public health practice and youth-focused interventions in Sub-Saharan Africa. They underscore the importance of exploring context-specific factors influencing activity levels. Enhancing measurement accuracy is vital for advancing evidence-based strategies and achieving Sustainable Development Goal 3. Full article

Climate change poses growing challenges to youth sports participation, but adolescent girls face disproportionate and compounding vulnerabilities. These arise from sex-specific physiological factors, sociocultural constraints, and institutional inequities that uniquely and disproportionately impact girls. These challenges are especially concerning considering the numerous health and well-being benefits of sports participation. However, there is a notable lack of research examining the specific impacts of climate change on adolescent girls’ sports participation, as well as evidence-informed strategies to mitigate these effects. The aim of this study is to (1) conduct a scoping review to better understand the impacts of climate change on adolescent girls’ sports participation and (2) examine the relationship between climate change and adolescent girls’ involvement in sports by integrating Ecologism and the Individual × Environment (I×E) frameworks. A search was conducted using four databases (PubMed, Scopus, SPORTDiscus and Web of Science), and a gray literature search was performed on Google. The search was limited to studies focusing on how climate change or weather variables impacted adolescent girls’ physical activity levels or sports participation. Studies must have been written in English, and all geographical regions were included. In total, 26 studies met the inclusion criteria. These findings were then analyzed by integrating Ecologism, which promotes sustainable infrastructure, and the Individual × Environment (I×E) framework, which highlights interventions tailored to individual and environmental interaction. Recommended strategies include climate-resilient facility design, equity-focused funding models, participatory research, and coordinated efforts from public health units and urban planning stakeholders. By integrating these frameworks, the paper proposes a comprehensive set of interventions that address both systemic ecological challenges and individual-level barriers, aiming to foster climate-resilient sports environments for adolescent girls.

Objectives: The present study aimed to examine the relationships between screen time (ST), sleep time (SLT), physical activity engagement (PA), Mediterranean diet (MD) adherence, body mass index (BMI), self-esteem (SE) and academic performance (AP) in high-socioeconomic-status (SES) school-aged youth in southern Spain. Methods: A descriptive, comparative, non-experimental and cross-sectional research study was conducted with a total sample of 217 Spanish students (13.88 ± 1.32). Structural equation modelling (SEM) was employed to analyse relationships between study variables as a function of sex. Results: SLT was positively associated with MD adherence and negatively related with BMI. Both PA and MD adherence were positively linked to SE, whilst MD adherence and SE were also positively related to AP. Regarding sex differences, ST was a stronger determinant among girls, showing negative associations with PA (β = −0.378; p < 0.001) and MD adherence (β = −0.315; p < 0.001), with this pattern not being observed in boys. PA was positively associated with SE in both sexes, but more strongly in boys (β = 0.332; p < 0.001) than in girls (β = 0.190; p = 0.034). In girls, both MD adherence (β = 0.295; p < 0.001) and SE (β = 0.224; p = 0.008) were positively associated with AP, with these associations not being found in boys. Conclusions: The findings underscore the complex interplay between lifestyle behaviours, psychosocial factors, and AP in school-aged youth. Regardless of SES, interventions should focus on reducing ST, promoting PA and MD adherence, and enhancing SE whilst considering sex-specific patterns. Full article

Self Determination Theory posits that individuals may be more likely to initiate and maintain behaviors tied to intrinsic (vs. extrinsic) motivations and may provide a useful framework for understanding youth participation in novel sports. Using the Intrinsic Motivation Inventory (IMI) and Patient-Centered Assessment and Counseling for Exercise Plus Nutrition (PACE+) surveys, motivation and physical activity habits were explored in 27 children/adolescents (ages 7–16) enrolled in Parkour, an individual, non-competitive youth sport. Fifteen Parkour participants were also interviewed to gain an understanding of their motivations for participating. Study participants had high median IMI subscale scores related to interest/enjoyment (6.71/7) and perceived choice (6.40/7) compared to the whole scale. Similarly median sub-scale Pros and Self-Efficacy scores for physical activity from the PACE+ were high (4.25/5 and 3.91/5, respectively). The themes of autonomy and enjoyment were consistently reported in the qualitative interviews, expanding on the quantitative results. Other themes included appreciation for camaraderie, creativity, and a drive for improvement. These results provide early evidence that Parkour, and similar lifestyle sports, may be tied more to intrinsic than extrinsic motivations and could have potential for adoption and maintenance by youth with low motivation to engage in physical activity to promote healthy behaviors.
