Povzetek: Purpose: The aim of this study is to determine the relationship between physical characteristics and performance in young alpine skiers in the Super-G discipline. Methods: A sample of 42 U16 alpine skiing competitors (23 boys and 19 girls) aged 14-15 years participated in the study. The physical characteristics were measured using the Inbody 720 Body Composition Analysis and 3D Body Scan devices. Performance data was obtained from official records of the Ski Association of Slovenia for the 2018/19 U16 competitive season. Variables such as body height, body weight, thigh circumference, waist circumference, chest circumference, shoulder circumference, muscle mass percentage, fat mass percentage, body mass index, and body fat percentage were analyzed. Pearson correlation coefficients and multiple regression analysis were used to assess the relationship between the physical characteristics and Super-G performance. Results: Significant correlations were found between body weight, thigh circumference, chest circumference, muscle mass percentage, and Super-G performance in boys. For girls, waist circumference, chest circumference, and body fat percentage were significantly correlated with performance. The multiple regression model explained 73% of the variance in the boys’ performance and 59% in the girls’, although the model itself was not statistically significant for predicting performance. Conclusion: Physical characteristics, especially muscle mass percentage and body circumferences, are significantly associated with Super-G performance in young alpine skiers. These findings underscore the importance of tailored training programs that consider individual physical characteristics to optimize competitive success in alpine skiing.

Povzetek: The paradox of rest lies in its dual nature: essential for recovery yet potentially harmful when prolonged. Prolonged physical inactivity (PI) significantly contributes to non-communicable diseases (NCDs). Studies show nearly a third of adults worldwide were insufficiently active in 2022, with the economic costs of PI projected to reach INT$520 billion by 2030. Bedrest models have illuminated the rapid onset of insulin resistance, general functional decline and muscle atrophy associated with PI, particularly in hospitalised older adults. Innovative technologies, such as extended reality (XR), offer promising solutions for mitigating the effects of PI and can enhance non-physical rehabilitation techniques such as motor imagery and action observation. These technologies provide immersive, personalised therapeutic experiences that engage multiple senses, transforming passive recovery into an active process and addressing both the physical and cognitive consequences of inactivity. Results of bedrest study showed significant preservation of muscle mass, improved strength and enhanced insulin sensitivity in the intervention group compared to controls. These findings highlight the potential of XRbased strategies in addressing structural and functional declines during inactivity. As part of the Interreg VI-A Italia-Slovenija project X-BRAIN.net, advanced XR-equipped active rooms were developed to aid post-stroke rehabilitation in acute care settings. XR technologies, particularly VR, have shown promise in providing dynamic and adaptable therapeutic environments that facilitate early and targeted interventions. Future advancements focus on integrating XR with brain-computer interfaces (BCIs) and synchronised visual-haptic neurofeedback, enhancing sensorimotor cortical activation and improving rehabilitation outcomes. Comprehensive multimodal approaches, including nutritional, physical and non-physical interventions, are emerging as effective strategies to personalise and optimise patient recovery.

Povzetek: Objective: Parkinson’s patients will experience mobility disturbances with disease progression. Beneficial effects of physical therapy are short-lasting. Novel interventions are needed to maintain these benefits. Methods: Fourteen Parkinson’s patients (71±4.08 years) participated in a randomized controlled examiner-blinded feasibility clinical trial. After 12 physical therapy sessions, the intervention group received a height-adjustable desk that facilitates stepping while standing, for 4 months. Explorative outcome measures included MDS-UPDRS II, III, TUG, 8.5m walking test, PDQ-39, sABC, sFES, DEXA scans, and lower extremity strength. Results: Post-physical-therapy, everyone significantly improved on the MDS-UPDRS II, III, TUG, and 8.5m walking test, and PDQ-39. (p<0.05) After 4 months, the control group regressed towards pre-physical-therapy values. In the intervention group, sedentary behavior decreased beyond desk use, indicating a carry-over effect. MDS-UPDRS II, PDQ-39, sFES, sABC, TUG, 8.5m walking test, activity time, sitting time, hip strength all improved with clinically relevant effect sizes. Conclusion: Postphysical therapy in-home reduction of sedentary behavior was associated with maintenance of physical benefits and additional improvements in mobility, activity time, balance and quality of life

Povzetek: Purpose: Forward head posture (FHP) is the most common cervical postural fault in the sagittal plane that can cause various issues and conditions. The purpose of this study is to determine the prevalence of FHP among sports-involved children and to examine the differences in craniovertebral angle (CVA) with regard to gender, age, neck pain, and the sports in which they participate.Methods: A cross-sectional study was conducted among 154 sports-involved chil-dren (76 males and 78 females), aged 11–14, participating in various sports (basket-ball, football, volleyball, and athletics). After obtaining signed consent, photography of the sagittal view was performed in a standing position, which was then used to measure the CVA using the Web Plot Digitizer software. A questionnaire was used to gather data about gender, age, sports in which a participant is involved, presence of neck pain, and pain scale.Results: Among the 154 children, 37 (24.03%) exhibited FHP (15 males, 22 fema-les). The mean CVA for the entire sample was 51.30° ± 6.20°. Female participants had a significantly lower CVA (p = .021) compared to male participants. No significant differences were found with regard to age, presence of neck pain, or engagement in a specific sport.Conclusion: FHP is present in sports-involved children, with a higher prevalence among females
