The COVID-19 pandemic, which emerged in early 2020, caused widespread disruptions to youth sport, including curriculum-based physical activity, organized sports, and active transportation. This study investigated the impact of repeated lockdowns on organized youth sport participation, physical fitness, skill development, and psychosocial well-being in Slovenia. An online survey was conducted between November and December 2021 with 116 coaches of U13–U19 athletes across multiple sports disciplines. Descriptive statistics and non-parametric analyses were employed to examine participation trends, training adaptations, and perceived athlete outcomes. Following the first lockdown, 14.6% of athletes dropped out, while 6.5% of teams reported increased membership. After the summer break, participation rebounded, and the second lockdown had a smaller impact, indicating partial resilience in youth sport engagement. Training frequency and modality were substantially affected, with 20% of coaches not implementing remote sessions and fewer than half conducting post-lockdown fitness assessments. Coaches reported declines in general physical fitness (71%) and sport-specific skills (70%), heterogeneous changes in body mass, and reduced self-confidence and motivation in over 50% of athletes, whereas team spirit remained relatively stable. A significant association between perceived changes in body mass and motivation highlighted the role of physical self-concept in supporting engagement. These findings demonstrate that prolonged interruptions to organized youth sport have multidimensional effects on physical, technical, and psychosocial development. Future research should explore long-term consequences, identify effective mitigation strategies, and consider sport-specific, age, and gender-related factors to enhance resilience in youth sports systems under exceptional circumstances.

Patients with Parkinson's Disease (PD) experience motor and non-motor symptoms that decrease their quality of life. The non-pharmacological management of PD is imperative to improve the quality of life for patients with the disease. Non-pharmacological management options such as exercise, medical, and surgical interventions can improve function and independence in patients with PD. Many non-pharmacological management options target specific symptoms commonly associated with PD. The Knowledge Attitude Practice (KAP) model was adapted to develop a questionnaire that assesses patient and practitioner knowledge of non-pharmacological management options for PD. The questionnaire consisted of 11 questions. To assess the relationship between sociodemographic variables and patient and practitioner knowledge of non-pharmacological management options likelihood-ratio chi-squared, Spearman's correlation, simple logistic regression, and multiple logistic regression analyses were performed on the collected data. Six hundred and forty-one participants completed the questionnaire. For patients (n = 492) and practitioners (n = 149), the most widely known non-pharmacological management option was regular exercise, and the least-known was subthalamotomy. Compared to patients, practitioners were more likely to have knowledge of most non-pharmacological management options (OR 1.73 - 7.36). Higher education level (OR 3.10 - 10.96), younger age (OR 0.09 - 0.32), geographical location (North America OR 0.05 - 0.49, Europe OR 2.24), employment status (OR 4.81 - 12.02), and sex (OR 0.59) had a significant relationship with patient and practitioner knowledge of non-pharmacological management options. Practitioners were more likely to have knowledge of most non-pharmacological management options for PD compared to patients. Several sociodemographic variables impacted one's ability to identify non-pharmacological management options in both populations. Increasing patient and practitioner knowledge of non-pharmacological management options could improve the care and quality of life of patients with PD.

Introduction: Adolescent idiopathic scoliosis (AIS) is a three-dimensional spinal deformity characterized by lateral curvature, vertebral rotation, and sagittal imbalance. It affects 2–4% of adolescents, predominantly females (7:1 ratio). Progressive deformity can cause respiratory dysfunction, chronic pain, and psychosocial distress. Developing effective conservative treatments remains a major challenge in orthopedic rehabilitation. This study aimed to evaluate the effectiveness of combined Schroth therapy and 3D-Chêneau bracing in managing AIS, focusing on sagittal alignment, postural control, and functional improvement. Material and Methods: A prospective quasi-experimental study was conducted with 60 adolescents (mean age 13.3 ± 1.6 years) diagnosed with AIS (Cobb angle 20°–47°). The intervention consisted of two phases: an intensive 3-week supervised Schroth exercise program (21 sessions) followed by continued home exercises combined with a custom 3D-modified Chêneau brace. Assessments were performed at baseline, 4 weeks, 3 months, and 6 months. Primary outcomes included sagittal balance (mm) and sagittal index (mm), evaluated by standardized plumb-line analysis. Results: After six months, significant improvements were observed in sagittal alignment (p < 0.001). Sagittal balance increased toward the physiological reference (~20 mm), indicating improved postural symmetry and trunk stability. Sagittal index values reflected curve-specific and localization-dependent adaptations, particularly in thoracic deformities. Conclusion: Combined Schroth therapy and 3D-modified Chêneau bracing effectively enhanced sagittal spinal alignment in adolescents with AIS. This integrated conservative approach demonstrated measurable improvements in physiological balance and postural organization, supporting its role as a functional, noninvasive intervention for AIS management.

Recently, entrepreneurship has become increasingly attractive to sports and physical education students. As a result, many students recognize entrepreneurship as an opportunity for career development and the achievement of professional goals. This study examines the entrepreneurial preparedness of sports and physical education students, revealing significant gaps in essential business skills despite high entrepreneurial interest. The findings highlight the need for enhanced educational programs to better equip graduates for successful entrepreneurial endeavors. Based on previous research, to analyze the readiness and understanding of entrepreneurship among students, assess their entrepreneurial capabilities, and evaluate their level of competence in running their own business. The following academic databases were used for literature search: Scopus (158 sources) and Web of Science (104 sources). A total of 262 references were found. After removing duplicates, 234 references remained. The following inclusion criteria were applied: 1. Articles published since 2010; 2. Studies written in English; 3. Research focused on the topic of entrepreneurship in sports and student entrepreneurship. The results of this study indicate that entrepreneurship in sports faces significant challenges, including limited employment opportunities and a lack of essential entrepreneurial skills among students. These challenges hinder the development of successful entrepreneurial initiatives in the sports sector, as students often lack adequate training in the areas of starting and managing a business. Moreover, the job market in sports offers relatively few employment opportunities, further complicating students' ability to find jobs or start their own entrepreneurial projects in this specialized field.

Female reproductive hormones such as progesterone and estrogen play an important role in the body as they orchestrate functions of numerous cells including skeletal muscle cells. Onset of menses marks the beginning of reproductive life, whereas menopause marks its cessation. We distinguish three phases of the 28-day menstrual cycle namely follicular, ovulatory and luteal phases. The follicular phase is characterised by marked increases in estrogen, which triggers ovulation. During this phase, estrogen peaks, whereas progesterone levels are low. Following ovulation, the luteal phase commences marked by high progesterone levels and reduced estrogen. Indeed, these periodic fluctuations in reproductive hormones may affect rates of muscle protein synthesis and hence hinder sought adaptations such as skeletal muscle hypertrophy in female athletes. With the introduction of hormonal contraceptives, female athletes were able to have ameliorate the negative effects of the menstrual cycle by reducing menstrual cramping and bleeding. Hormonal contraceptives are constituted of a single or multiple synthetic hormones namely estrogen and progestin. Nevertheless, the impact of hormonal contraceptives on skeletal muscle hypertrophy remains elusive. In this review, we aim to present the potential implications of hormonal contraceptives on skeletal muscle hypertrophy.

The goal of the research was to determine the effects of six weeks of isoinertial training on explosive strength, speed, and agility compared to traditional strength training in tennis players. The subjects, thirty male tennis players aged 20 to 35, were divided into three groups: the experimental group 1 (E1; n=10), which performed strength training on an isoinertial device; the experimental group 2 (E2; n=10), which performed traditional strength training; and the control group (C1; n=10). E1 and E2 groups had a total of six weeks of training with two training sessions per week, with three exercises per training session performed in four series for six to eight repetitions. The results showed that isoinertial strength training has a positive effect in the variables squat jump (SJ), countermovement jump (CMJ), 5-meter sprint (5M), 20-meter sprint (20M), agility T-test (T-test), and 505 agility test (505). Post hoc analysis revealed that there are significantly better effects of isoinertial training compared to isodynamic training in the countermovement jump (CMJ), 5-meter sprint (5M), and 20-meter sprint (20M). The E1 group had significantly better results than the C1 group in all tests. The E2 group had significantly better results compared to the C1 group in the variables SJ, 20M, and T-test. The results also show that six weeks of isoinertial training produce better results in the development of variables CMJ and 20M compared to the traditional strength training group. Accordingly, fitness and tennis coaches should also use this training method when working with tennis players.

Vascular entrapment syndromes of the lower extremities represent a diagnostic challenge in athletes, with emerging evidence suggesting sport-specific presentations. This study aimed to characterize and compare patterns of vascular compression, anatomical variants, and hemodynamic consequences across different sporting disciplines. We conducted a retrospective analysis of 210 athletes with confirmed vascular entrapment syndrome from a 10-year cohort (2014-2023). Athletes were categorized as long-distance runners (n=87), cyclists (n=71), triathletes (n=24), soccer players (n=19), and other sports (n=9). All participants underwent standardized clinical assessment and vascular imaging during provocative maneuvers. Multivariable analyses and latent class analysis were performed to identify independent predictors and distinct phenotypes. Sport-specific patterns of vascular compression were identified. Long-distance runners exhibited highest compression during plantarflexion (85.7±8.6%), predominantly with Type III gastrocnemius variants (60.9%). Cyclists demonstrated highest compression during knee extension (79.2±11.4%), with predominant Type II variants (49.3%). Soccer players exhibited primarily Type I variants (57.9%) with lower compression severity. Latent class analysis identified three distinct phenotypes: "runner phenotype" (43.8%), "cyclist phenotype" (37.1%), and "low compression phenotype" (19.0%), each with characteristic anatomical, hemodynamic, and clinical features. Sport category remained an independent predictor of compression severity after adjusting for potential confounders (p<0.001). Vascular entrapment syndrome manifests with distinct sport-specific patterns reflecting the interplay between anatomical predisposition and functional demands. The identification of sport-specific phenotypes provides a framework for tailored diagnostic approaches and management strategies. Recognition of these characteristics may enhance diagnostic accuracy, inform individualized treatment, and improve outcomes for affected athletes across diverse sporting disciplines.

This scoping review investigates the effects of Pilates exercise interventions on health and quality of life of older adult women. Through a comprehensive examination of existing literature, this review identified key areas where Pilates has shown to significantly benefit physical capabilities such as strength, balance, and flexibility, alongside mental health improvements, including reduced symptoms of depression and anxiety, and enhanced sleep quality.  Thus, this scoping review emphasizes a possible role of Pilates in addressing age-related physical and psychosocial challenges, and suggests it as suitable low-impact exercise for promoting healthy aging. Despite the methodological heterogeneity among studies, the overall evidence suggests that Pilates may be a valuable component of geriatric healthcare strategies. The findings advocate for further research to expand the evidence and further guiding healthcare professionals in integrating Pilates into exercise prescriptions for older adult women.

Modern directions in the development of physical education in the world emphasize the importance of health-related physical fitness (HRPF), with special attention to the development and monitoring of knowledge about HRPF through the application of a targeted questionnaire. The main goal of this research was to analyze the characteristics of the HRPF questionnaire adapted to the Serbian language. After adjustment to Serbian language and terminology, questionnaire was administered to a sample of 270 children, 175 children of the fifth grade (11 to 12 years) and 95 children f the eighth grade (14 to15 years). In both subsamples, the questionnaire has shown good internal consistency (Cronbach's α was 0.73 for fifth grade and 0.67 for eighth grade) and good features of most questions. The results also suggested problems with three questions which needed adjustment for further use: Question Q2 - Jana wants to do something after school what would help her to become successful in the football team she plays in, she should; Question Q11 - Volleyball is good; Question Q25 - If you want to be stronger, you should. After that kind of implementation, the questionnaire can be recommended for evaluation of HRPF of older primary-school children.
