14. Adherence and metabolic outcomes of early and late time-restricted eating with energy restriction vs. energy restriction alone : a 6-month follow-upTanja Črešnovar, Bernarda Habe, Nina Mohorko, Saša Kenig, Zala Jenko Pražnikar, Ana Petelin, 2026, izvirni znanstveni članek Opis: Background/Objectives: Long-term weight maintenance remains challenging with conventional dietary strategies due to various barriers. Time-restricted eating (TRE) has recently attracted attention as a potential approach to improve adherence, but evidence on long-term maintenance is limited. We investigated the 6-month follow-up (6FU) of early time-restricted eating with energy restriction (eTRE + ER), late time-restricted eating with energy restriction (lTRE + ER) and energy restriction alone (ER). Methods: This 6FU included 69 of 93 participants from a previously conducted 3-month intervention (3INT). After the intervention, participants returned to free-living conditions without dietary guidance. Outcomes included adherence, perceived barriers, body composition, blood pressure, cardiometabolic risk factors, metabolic hormones, subjective appetite, and dietary intake. Results: Adherence of at least ≥5 days per week was low: 7.7% (eTRE + ER), 18.2% (lTRE + ER), and 9.5% (ER). Reduced adherence during the 6FU was associated with a partial reversal of improvements in body mass, body composition, cardiometabolic risk factors, metabolic hormones, and subjective appetite observed during the 3INT. Analysis of perceived barriers showed that environmental and psychosocial barriers were significant predictors of changes in body mass during the 6FU, while environmental and behavioral barriers were associated with extension of the eating window. These associations were most pronounced in the eTRE + ER group. Conclusions: During the 6FU, differences between dietary strategies gradually diminished, although some remained clinically meaningful. Long-term adherence was low across all three dietary strategies, with psychosocial, environmental, and behavioral barriers particularly evident in the eTRE + ER group. Further research is needed to confirm long-term adherence before TRE + ER interventions can be widely applied in clinical practice.

15. Machine learning identifies distinct movement control impairment clusters in patients with chronic neck painŽiva Majcen Rošker, Jernej Rošker, 2026, izvirni znanstveni članek Opis: atients with chronic neck pain experience various impairments, with reduced movement control suggested as a significant contributing factor. The heterogeneity of this patient population and suboptimal rehabilitation outcomes suggests the existence of latent subgroup characteristics. The aim of this study was to identify distinct groups among patients with neck pain based on the movement control test and pain intensity and to provide information on cluster-specific impairments. 135 patients with idiopathic neck pain performed a movement control test (the Butterfly test) at three difficulty levels and were assessed for pain intensity, providing 13 different parameters (classifiers). Louvain, hierarchical and k-means clustering methods were applied and the number of clusters determined by observing the symmetry and size of silhouette scores. Further, different machine learning algorithms were applied to develop and evaluate a classification framework (based on AUC, classification accuracy, sensitivity, and specificity) and to provide information on individual cluster characteristics using the Shapley Additive Explanations. The k-means and deep learning neural network methods provided the most efficient clustering and classification performance extracting 4 meaningful clusters. Patients between groups differed in the amount of impairment, with cluster 2 and 1 representing the most severe impairments and with clusters 3 and 4 the least severe impairments. Additionally, specific motor control impairments were observed in individual clusters suggesting distinct neck movement control adaptations. Identifying subgroups of patients with neck pain and their specific characteristics based on the results of the Butterfly test may inform future development of targeted rehabilitation strategies.

19. Comparison of vertical jump performance between the Maasai, track and field athletes, and non-athletes : a cross-sectional studyPetra Robnik, Jaffu Chilongola, Eunice Kombe, Žiga Kozinc, 2026, izvirni znanstveni članek Opis: The Maasai are known for their unique customs, including dancing, singing, and jumping. The tribe’s traditional jumping rituals, performed by young warriors called ‘Morani,’ demonstrate their strength and skill through repetitive hops, often lasting several hours. These jumps are comparable to the countermovement jumps (CMJ) of elite Western athletes. This study compared different types of jumps (CMJ), squat jump (SJ) and repetitive hops) among three groups: (a) Maasai (n = 30), (b) Slovenian high-jump athletes and sprinters (n = 20), and (c) non-athletes in Slovenia (n = 20). Participants were male, aged 16–35. The My Jump 2 app was used to measure jump height. Results showed that during CMJ, the Maasai averaged 38.1 cm ± 7.3 cm; athletes 52.46 cm ± 9.07 cm; non-athletes 33.72 cm ± 7.22 cm. In the SJ, the Maasai averaged 35.87 cm ± 6.59 cm; athletes 49.74 cm ± 7.3 cm; non-athletes 32.57 cm ± 6.21 cm. For repetitive hops, the Maasai averaged 36.2 cm ± 7.75 cm; athletes 35.93 cm ± 5.98 cm; non-athletes 20.98 cm ± 7.07 cm. Athletes showed higher jump heights in CMJ and SJ compared to the Maasai (p < 0.001, d = 1.28; p < 0.001, d = 2.00) and non-athletes (p < 0.001, d = 2.29; p < 0.001, d = 2.53). However, in repetitive hops, the Maasai performed similarly to athletes (p = 0.991, d = 0.04), while non-athletes had significantly lower results (p < 0.001, d = 2.05). These findings suggest that the Maasai’s cultural practices enhance musculoskeletal adaptation from an early age, emphasizing that proficiency is greatest in regularly practiced tasks, such as repetitive jumps and hops.

20. Health and performance challenges in the era of human enhancement : insights from sport medicine professionalsKe Hu, Mark R. Hutchinson, Emin Ergen, Norbert Bachl, Petra Zupet, Bertrand Fincoeur, Anca Ionescu, Borja Muniz-Pardos, Andrea Petroczi, Yannis Pitsiladis, 2025, izvirni znanstveni članek Opis: Background In the pursuit of sporting success, some elite athletes prioritise peak performance over long-term health, frequently resulting in significant and enduring health consequences. The Enhanced Games (TEG) position themselves as a bold experiment in transhumanism, advocating for the use of performance-enhancing drugs (PEDs), including methods banned by World Anti-Doping Agency (WADA), to push the boundaries of human athletic potential. Objectives The aim of this study is to explore the perspectives of sport physicians, sport scientists, physiotherapists and other allied healthcare professionals on treating and supporting “enhanced athletes”, with the view of informing future guidelines. Methods Participants were invited via email and personal contacts within sport medicine communities to complete a brief anonymous survey via QuestionPro™. Descriptive statistics were performed using Excel™ and RStudio™. Results A total of 323 healthcare professionals responded (82% were sport physicians), among whom 74% expressed a willingness to treat acute lesions and/or chronic diseases in “enhanced athletes”. In comparison, a considerable minority (30%) expressed support for assisting athletes in their use of PEDs and methods under medically supervised conditions, with high consistency across professional roles. A relatively high readiness was observed in sport physicians treating acute (77% versus 58%; p < 0.01) and chronic (75% versus 63%; p = 0.11) diseases for “enhanced athletes”. As far as WADA rules and/or national anti-doping laws apply, this support presupposes compliance with the code and the respective national laws to protect physicians from serious professional, legal and personal consequences. Conclusion The preliminary findings align with the broader goal of fostering a sport culture that values both peak performance and the short- and long-term health of all participants. These results emphasise the necessity of implementing professional guidelines and comprehensive support systems designed to safeguard the long-term well-being of all athletes and underscore the urgent need for further research into the impact of TEG on sport and its community.
