Stretching is commonly recommended to improve flexibility and reduce injury risk; however, its practical implementation among recreational snowboarders and alpine skiers remains inconsistent. A cross-sectional online survey was conducted during the 2024–2025 winter season. Of 403 collected responses, 391 valid questionnaires were included after data screening. The survey assessed sociodemographic characteristics, stretching perceptions, practices, perceived barriers, information sources, and supervision. Descriptive statistics and chi-square tests were used to explore associations between sport modality and generational cohorts. Although 91.3% of participants considered stretching necessary, only 39.7% reported performing stretching exercises in the previous six months. The most frequently reported barriers were lack of time (76.1%) and low motivation (54.2%). Alpine skiers attributed greater importance to stretching than snowboarders. Significant generational differences were observed in sport modality, practice volume, and information-seeking behaviour (p < 0.05), but not in stretching frequency or duration; therefore, Hypothesis 1 was not supported. Only 22.7% of participants reported receiving professional supervision. In recreational winter sports, stretching is widely valued but inconsistently practiced. Behaviour appears to be driven more by motivational and contextual factors than by generational differences in practice frequency, highlighting the need for targeted educational strategies and evidence-informed guidance.

Background/Objectives: Energy availability (EA) is associated with Relative Energy Deficiency in Sport syndrome. This study assessed the EA, body composition, and phase angle (φ) of adolescent artistic gymnasts during a competitive season. Methods: Thirty non-elite artistic gymnasts aged 11–14 years participated in this cross-sectional study. Anthropometric data were collected and body mass index (BMI) was assessed using the World Health Organization growth charts. Bioelectrical impedance analysis was performed and diet and physical activity were recorded for three days. Dietary and physical activity records were analyzed to estimate energy intake, total energy expenditure (TEE), and exercise energy expenditure, from which energy balance (EB) and EA were calculated. The 95% confidence ellipses of the impedance (Z) vectors were compared with a reference population using the two-sample Hotelling’s T² test. Correlations between variables were examined by Pearson’s or Spearman’s correlation analysis. Statistical significance was set at α = 0.05. Results: All participants were classified within the normal BMI category, except for one who was classified as being overweight. Mean (± SD) fat mass, fat-free mass (FFM), and φ were 16.1 ± 3.4%, 83.9 ± 3.4%, and 6.0 ± 0.6°, respectively. The 95% confidence ellipses of Z vectors differed significantly from the reference population. Energy balance was 32 ± 223 kcal/day and EA was 49.2 ± 11.4 kcal/kg FFM/day. Energy availability was significantly correlated with EB, TEE, and body composition variables. Conclusions: Adolescent non-elite artistic gymnasts showed no clear indications of LEA and exhibited a normal body composition and φ during the competitive season, consistent with their EA.

This study aimed to develop load–velocity (L-V) profiles for prone bench pulls and half squats in elite female traditional rowers, and to assess their association with rowing performance. Eight highly trained female rowers, members of the team that won the Spanish Traditional Rowing Championship, completed a graded exercise test (GXT) on a rowing ergometer, followed by one-repetition maximum (1RM) and incremental loading tests. L-V profiles were established using mean velocity (MV) data collected with a linear velocity transducer. Correlation analyses were conducted to examine the associations between movement velocities at specific relative loads and GXT performance. The slope of the linear regression was slightly higher for the prone bench pull (MV = −0.0127 m·s⁻¹) than for the half squat (MV = −0.0104 m·s⁻¹). A similar correlation could be observed, although slightly higher, for the half squat (r = 0.929; p < 0.001) exercise compared to the bench pull (r = 0.922; p < 0.001). In this exploratory analysis, a statistically significant correlation was observed between rowing performance and MV at 30% 1RM for both exercises (r = 0.856 and r = 0.866, respectively; p < 0.05). No other load intensities demonstrated statistically significant correlations with performance. The findings highlight the utility of L-V profiling at lower relative loads in traditional rowing performance among elite female athletes. The results support the application of velocity-based training (VBT) in rowing-specific strength programs and suggest that performance optimization may be achieved through high-velocity movements performed with submaximal loads. Furthermore, this study reinforces the value of individualized L-V profiles and real-time velocity monitoring for tailoring resistance training interventions. Full article

Objective: This study evaluated the effects of a 12-week High-Intensity Functional Training (HIFT) program combined with thylakoid supplementation on plasma adipo-myokine levels (Decorin, Myostatin, Follistatin, Activin A, and TGF-β1) in men with obesity. Secondary outcomes included anthropometric indices, lipid profiles, and insulin resistance markers. Methods: Sixty men with obesity (age: 27.6 ± 8.4 years; BMI: 32.6 ± 2.6 kg/m²) were randomly assigned to four groups (n = 15 per group): Placebo (PG), Supplement (SG), HIFT + placebo (TPG), and HIFT + supplement (TSG). To ensure robustness against the 27% attrition rate, statistical analyses included both per-protocol and intention-to-treat (ITT) models. HIFT was performed for 3 sessions/week (Borg scale: 15–17). Results: Following Bonferroni correction for multiple endpoints, repeated-measures ANOVA showed significant Time × Group interactions for most adipo-myokines and metabolic markers. Both training groups (TPG and TSG) demonstrated improvements in body composition and insulin sensitivity compared to PG (p < 0.05). While no significant differences were observed between TPG and TSG for systemic metabolic markers, preliminary data suggested that thylakoid supplementation might provide modest complementary modulations in specific myokines (e.g., decorin and follistatin). However, these observed trends did not reach clinical superiority over exercise alone in the broader metabolic profile. Conclusions: Twelve weeks of HIFT is an effective primary driver for modulating the adipo-myokine network in obese men. Although thylakoid supplementation showed potential for selective complementary effects on certain myokines, these findings are exploratory given the small sample size. The clinical significance and long-term complementary value of thylakoid-exercise interactions require further validation in larger, more diverse cohorts. Full article

Body composition, bone mineral density, and cardiopulmonary exercise testing (CPET) are commonly used to assess aerobic fitness in athletes, but their interrelationships remain unclear. This study compared these parameters by sex and examined their associations in elite athletes. Our study included 145 youth water polo players (age: 15.7 ± 1.6 years; male: 75). Body composition was measured by DEXA, and treadmill CPET was performed using a sport-specific protocol. We analysed the correlations between the following factors by multivariate linear regression: lean body mass (LBM, LBM_index); body fat mass (BFM); percent body fat (PBF); bone mineral content (BMC); lumbar, femoral, and radial bone mineral density (LBMD, FNBMD, FTBMD, RBMD); exercise time; absolute and relative maximal oxygen uptake (VO_2absmax, VO_2relmax); maximal ventilation (VE_max). Exercise time was found to be negatively correlated with BFM, while VO_2relmax was found to be negatively correlated with BFM and PBF. VO_2absmax was found to be positively correlated with BFM, LBM, BMC, FNBMD, and RBMD. VE_max was found to be positively correlated with LBM and LBM_index. In males, VO_2absmax and VE_max were found to be positively correlated with LBMD and FTBMD. Correlations between bone density and CPET proved to be stronger in males. Our results indicate that body composition and bone density parameters influence CPET parameters, and their complex evaluation can support personalized diagnostics and athletes’ health. Full article

Objective: This study aimed to systematically evaluate the effects of hypoxic exercise at different oxygen concentrations on body composition, glucose metabolism, and lipid metabolism in individuals with obesity, and to explore potential optimal oxygen concentration ranges to inform personalized hypoxic exercise prescriptions. Methods: We searched databases including the Cochrane Library, PubMed, Web of Science, Embase, and CNKI for randomized controlled trials and pre-post studies on hypoxic exercise interventions in obese populations published before 30 June 2025. A network meta-analysis was performed using Stata 18.0 software to assess the effects of various oxygen concentrations on BMI, FBG, FINS, HOMA-IR, TG, LDL-C, and HDL-C. Subgroup analyses were conducted to explore sources of heterogeneity. Results: Fourteen studies with a total sample size of 189 participants were included. The meta-analysis revealed that exercise in a moderate hypoxic environment (12–14% FiO₂) significantly reduced BMI, FBG, TG, and LDL-C. Notably, hypoxic exercise did not show a statistically significant effect on HDL-C. In contrast, a higher oxygen concentration (≥15% FiO₂) was more effective for improving FINS and HOMA-IR. Conclusion: Hypoxic exercise can significantly improve the body composition, glucose metabolism and lipid metabolism indicators of obese people. Tailored exercise in specific hypoxic environments provides preliminary evidence for a non-pharmacological intervention strategy in obesity management. Full article

Background: In recent years, growing attention has been paid to the lifestyle factors that influence young adults’ well-being. University students represent young adults at risk of Sedentary Behavior (SB) and mental distress. Sport Science students represent a health-conscious population, less prone to mental distress. This study aims to investigate the associations between physical activity (PA) levels, different determinants of quality of life (QoL), orthorexia nervosa (ON) symptoms, and internet use among Sport Science students living in Naples. Methods: An online survey comprising General Data (GD) and eight validated questionnaires was used to assess PA levels, mood, sleep quality, eating habits, and digital behavior in a population of university students enrolled in Sport Science courses at Parthenope University, Naples. The statistical analyses included descriptive statistics, Student’s t-test, a Mann–Whitney U Test, frequencies, chi-square tests, and a Spearman’s rank correlation. All the analyses were performed using JASP and Jamovi software. Results: We surveyed 775 students (472 M; 303 F; 22.85 ± 3.85 y; BMI 23.74 ± 3.63 kg/m²). Regarding the MET-min/week, 65% of participants reported being highly active, 28% moderately active, and 7% inactive. Poor sleep quality was reported by 20% of those surveyed. Additionally, 84% of participants declared average internet use, which positively correlated with their emotional profile and sleep quality. High PA levels were directly associated with the presence of ON symptoms in 27% of the participants, most of whom exercised in gyms. Conclusions: To our knowledge, this is the first study conducted on a study population of Sport Science University students addressing the complex and interconnected relationships between PA levels, QoL, ON symptoms, and internet use.

Ankle injuries are among the most common sports injuries in basketball and represent a substantial public health and economic burden. This narrative review synthesises evidence on ankle bracing as external protective support and shows that ankle braces reduce the risk of both first-time injuries and ankle re-injuries in basketball players without significantly affecting sport-specific performance, such as sprinting, jumping, or changing direction. Similarly, despite earlier theoretical concerns, current evidence shows no increased risk of knee injury associated with the use of ankle bracing. Mechanistic studies indicate that protection is provided by limiting excessive frontal-plane motion, enhancing proprioceptive feedback, and increasing perceived joint stability. Economic analyses show that a single ankle injury generates considerable direct and indirect costs, whereas seasonal team-wide ankle bracing programmes are low cost per athlete and likely cost-effective at scale. As a public health measure, ankle bracing is practical and easily scalable in community and sports settings. Overall, routine ankle bracing is shown to be a feasible, low-cost strategy for primary and secondary prevention of ankle injuries in basketball without compromising performance, and may support broader participation goals aligned with Sport for All principles.

This article presents a systematic, comparative, and reproducible mapping of the scientific literature examining how the term glocalization is mobilized in contemporary research. We analyze a corpus of 2200 articles (1990–September 2025) from Web of Science and Scopus and report in line with PRISMA 2020 and PRISMA-ScR (scoping). Methodologically, we combine PRISMA-ScR-aligned screening with the bibliometric and lexicometry mapping of metadata, complemented by the qualitative interpretation of a purposive subset of key texts to contextualize the mapped trajectories. Following normalization, we apply co-occurrence and correspondence analyses to identify lexical proximities and cross-disciplinary translation zones. We ask how glocalization is conceptualized, the contexts in which it is deployed, and whether classic theoretical frameworks retain their explanatory power. Findings show a gradual shift from a mainly conceptual to more operational register. Regional differences are marked yet organized around a core of governance, multilevel coordination, and collective practice. The disciplinary landscape shows continuity between techno-applied and reflexive approaches, supported by bridging disciplines (sociology, communication, education, health, sport) that translate a general grammar into research and intervention tools. We offer a cumulative methodological framework for tracing the scientific trajectory of glocalization. As a bridge concept between theory and action, glocalization provides an explanatory lens on transformations and resistances in early-twenty-first-century globalized society. We therefore position this study as a PRISMA-traceable corpus construction combined with bibliometric and lexicometry science mapping. Full article

Background/Objectives: The transition to higher education is often accompanied by lifestyle changes that may influence sleep habits, physical activity, and social media use, with potential consequences for physical and mental health. Methods: A quantitative, cross-sectional, descriptive, and correlational study was conducted using an online questionnaire administered between April and May 2024. The sample included 201 participants (123 students and 78 teaching/non-teaching staff). Data were collected using the Mental Health Inventory-5 (MHI-5), Social Media Addiction Scale (SMAS), Global Physical Activity Questionnaire (GPAQ), and Pittsburgh Sleep Quality Index (PSQI). Descriptive statistics and Spearman correlation analyses were performed. Results: Students presented lower mental health scores compared to staff members. Sleep quality indicators, particularly reduced sleep efficiency and increased use of sleep medication, were significantly associated with poorer mental health. Correlations between physical activity, social media use, sleep quality, and mental health were generally weak, suggesting that these domains contribute independently to perceived well-being. Staff members showed slightly higher levels of social media addictive behaviors, while students reported shorter sleep duration and greater emotional variability. Conclusions: The findings indicate that students presented lower mental health scores and poorer sleep indicators compared to staff members. Sleep quality—particularly sleep duration, efficiency, and use of sleep medication—showed the most consistent associations with mental health, while physical activity and social media use demonstrated weaker relationships. These results highlight the relevance of targeted sleep-focused interventions within higher education settings, especially for students in low-density regions. Full article

Objective: This double-blind, parallel-group randomized controlled trial is the first to investigate the synergistic effects of interval resistance plus progressive aerobic training with fisetin supplementation on adipokines in obesity. Methods: Sixty sedentary men with obesity (BMI < 30 kg/m²) completed 12 weeks of thrice-weekly interval resistance training (eight exercises, 3 × 13 reps at 60% 1RM with 20% 1RM active rest), immediately followed by staged aerobic bouts (50–70% HRmax). Participants were randomized into the control-placebo (P), fisetin (F; 200 mg/day), training-placebo (TP), or training + fisetin (TF) groups. The primary outcomes were asprosin, MCP-1, and adiponectin; secondary outcomes included leptin and lipid profile. Data were analyzed via ANCOVA with Bonferroni post hoc tests. Results: Statistical analyses were conducted following the intention-to-treat (ITT) principle using an analysis of covariance (ANCOVA) model, which revealed extensive effects of the interventions on the participants’ anthropometric and biochemical indices. Regarding body composition, after adjusting for baseline values, a significant difference in mean body weight was observed between groups (F (3, 55) = 9.444, p < 0.001, ηp² = 0.340); Bonferroni post hoc tests confirmed that the training plus fisetin (TF), training-placebo (TP), and fisetin (F) groups all achieved significant weight loss compared to the placebo (P) group. Furthermore, body mass index (BMI) showed a significant inter-group difference (p = 0.021), with post hoc analysis revealing that only the TF group reached a statistically significant reduction compared to the placebo (p = 0.024; 95% CI [−3.760, −0.172]). In the assessment of biochemical and inflammatory variables, the interventions exerted a highly significant effect on asprosin (F (3, 55) = 36.047, p < 0.001; ηp² = 0.663) and MCP-1 (F (3, 55) = 29.570, p < 0.001; ηp² = 0.617). The findings indicated that the TF group experienced the most substantial reductions in both asprosin (−60.71%) and MCP-1 (−46.50%) levels. Regarding adipokines, significant increases in adiponectin levels were observed in the TP (29.38%) and TF (27.67%) groups (p < 0.05), whereas changes in leptin were statistically significant only in the TF group relative to the placebo (p = 0.049). The lipid profile results indicated a statistically significant difference in the TF group in improving all markers; this group achieved greater reduction compared to other groups, including reductions in LDL-C, triglycerides (TG), and total cholesterol (TC) (p < 0.001), while simultaneously showing a significant elevation in HDL-C. Post hoc analyses confirmed robust statistical differences in all lipid parameters for both the TF and TP groups compared to the placebo group (p < 0.05), whereas the placebo group experienced a deterioration in status characterized by a significant increase in LDL-C (p = 0.027) and a significant decline in HDL-C concentrations (p = 0.006). Conclusions: In conclusion, 12 weeks of combined interval resistance–aerobic training and fisetin supplementation significantly reduced pro-inflammatory adipokines and improved lipid profiles in obese men. These findings suggest that asprosin serves as a potential modulator in metabolic risk reduction; however, since direct mechanistic assays were not conducted, these implications remain hypothetical. Future research employing molecular readouts is warranted to confirm the underlying pathways involved. Full article

Background: Gustatory dysfunction represents an underrecognized complication that may influence dietary behaviors and metabolic control. Previous investigations have suggested alterations in taste in patients with diabetes, yet the relationship between disease duration and specific taste modalities remains incompletely characterized. Aim: This study aimed to (i) compare orosensory detection thresholds for lipid and sweet tastes between patients with recent type 2 diabetes mellitus (rT2DM) (duration ≤ 5 years) and chronic type 2 diabetes mellitus (cT2DM) (duration > 5 years), and (ii) determine whether diabetes duration is associated with alterations in chemosensory function in a North African population. Methods: A cross-sectional comparative pilot study was conducted at the National Institute of Nutrition and Food Technology in Tunis, Tunisia, from April to June 2021. Sixty-seven patients with type 2 diabetes mellitus (T2DM) receiving oral antidiabetic medication were recruited through systematic sampling and divided into two groups: rT2DM (n = 30, duration ≤ 5 years) and cT2DM (n = 37, duration > 5 years). Orosensory detection thresholds for lipid taste were assessed using eight ascending concentrations of linoleic acid ranging from 0.018 to 12 mmol/L. In contrast, sweet taste thresholds were evaluated using a sucrose concentration series ranging from 0.01 to 5 mmol/L. The three-alternative forced-choice method with an ascending-concentration presentation was employed for both taste modalities. Detection thresholds were defined as the lowest concentration at which participants correctly identified the taste quality. Results: Patients with cT2DM exhibited significantly elevated orosensory detection thresholds compared to those with rT2DM for both taste modalities tested. The median linoleic acid detection threshold was 6.000 mmol/L in cT2DM versus 0.058 mmol/L in rT2DM (p < 0.001), representing a 107-fold increase in detection threshold. For sweet taste, the median sucrose detection threshold was 1.0 mmol/L in cT2DM compared with 0.5 mmol/L in rT2DM (p < 0.001), indicating a 2-fold increase in the threshold. In the overall patient cohort, the duration of diabetes was positively correlated with both fat taste perception thresholds (r = 0.657, p < 0.001) and sweet taste perception thresholds (r = 0.466, p < 0.001). However, when analyses were performed by diabetes duration-based subgroups, these correlations were observed only for fat taste perception in cT2DM, with no statistically significant correlations found in rT2DM. In multivariate linear regression analyses adjusted for age, body mass index, and sex/gender, the duration of diabetes remained independently associated with fat and sweet taste perception. Conclusions: Extended T2DM duration is associated with substantial elevations in orosensory detection thresholds for both lipid and sweet tastes in a North African population. These findings suggest that disease chronicity may contribute to chemosensory impairment, potentially influencing dietary preferences and metabolic control in patients with diabetes. Full article

This multi-institutional study examined pre-arrival confidence and perceived importance among first-year sport students across three post-92 universities and one public research university exploring programme of study, gender, and institutional differences, while also evaluating the psychometric properties of the pre-arrival survey. Of 1033 eligible students, 604 (58%) completed the survey across 25 sport-related programmes grouped into six categories: physiotherapy and rehabilitation, sport and exercise science, sports exercise and nutrition, sports coaching, sports management, and sport foundation year. Psychometric validation of the pre-arrival survey demonstrates its reliability and validity, providing the sector with a robust, standardised tool for assessing incoming students’ preparedness. Significant programme differences include physiotherapy and rehabilitation students reporting higher learning confidence, learning importance, and community confidence compared to other programmes. Female students demonstrated significantly higher learning importance and health and well-being importance than male students, though no gender differences in confidence were observed. Institutional variation was minimal, with one institution showing higher learning importance. Socioeconomic indicators did not significantly influence pre-arrival responses. The findings highlight the need for differentiated pre-arrival support targeting programme-specific confidence gaps and gender-related differences in perceived importance. The validated PAS provides a reliable tool for early identification of students requiring enhanced transitional support, potentially addressing persistent retention and progression challenges in UK sport programmes.

Peak bone mass gained in youth is crucial for preventing osteoporosis. Artistic gymnastics (AG) is highly osteogenic, yet its long-term effects on adults ≥ 45 years are not well documented. This case–control study compared bone mineral density (BMD) and the prevalence of osteopenia/osteoporosis in former gymnasts, age-matched controls, and reference populations from Brazil and Portugal. Participants included 65 former gymnasts (32 males, 33 females; 45–84 years), who trained for 12.6 ± 4.3 years and included 41 international competitors, and 91 controls (37 males; 45–87 years). Whole-body and femoral BMD were assessed by DXA. Physical activity during youth (10–20 years) (PA-Youth) and the past decade (PA-10) was recorded. Reference data were drawn from large cohorts in Brazil (FIBRA, n = 828) and Portugal (CIAFEL, n = 1089). Former gymnasts had substantially higher PA-Youth than controls, while PA-10 was similar. Gymnasts displayed 4–6 times higher femoral Z-scores (neck and total) and a markedly lower prevalence of osteopenia/osteoporosis (males: 3% vs. 16%; females: 36% vs. 52%, p < 0.05). These benefits remained after adjustment for age, PA-10, and hormonal/calcium therapy. Relative to reference populations, gymnasts showed greater whole-body and femoral mineralization, with no osteoporosis cases (vs. 6–12% overall; 9–13% among those ≥60 years). Age-stratified analysis (45–59 and ≥60 years) revealed a consistently lower osteopenia prevalence across age groups, except in females ≥ 60 years. In conclusion, early-life AG participation is associated with enduring skeletal benefits, including higher bone mineralization and reduced osteopenia/osteoporosis in adults ≥ 45 years. The protective effect appears diminished in older females, likely reflecting prolonged postmenopausal bone loss. Full article
