Active Child, Accomplished Youth: Middle Childhood Active Leisure Fuels Academic Success by Emerging Adulthood.

Background/Objectives: Physical activity is an important protective factor throughout life. However, little research has observed the associations between the practice of physical activity and academic success longitudinally, and none have done so with a pan-Canadian sample. This article aims to examine the prospective associations between active leisure in middle childhood and academic achievement in emerging adulthood, for both boys and girls, beyond several family factors. Methods: Participants are 2775 children from the National Longitudinal Study on Children and Youth (NLSCY) aged between 12 and 20 years. Active leisure was self-reported by children at age 12 years regarding their weekly organized sport, artistic sport, and unstructured physical activity participation outside of school hours. Academic success was measured by self-reported school average at age 18 years and the obtention of high school diploma at age 20 years. Results: Girls who engaged in more organized or artistic sports at age 12 years had better academic results at age 18 years (respectively β = -0.082, p < 0.01; β = -0.228, p < 0.001). Both boys and girls who partook in more organized sports at age 12 years were more likely to graduate from high school by age 20 years (respectively β = -0.146, p < 0.001; β = -0.071, p < 0.05). However, girls who engaged in more unstructured physical activity at age 12 years had lower academic achievement at age 18 years (β = 0.077, p < 0.001). Conclusions: Policy makers should aim to reduce the many barriers to an active lifestyle in childhood. Parents should be encouraged to lead their children to go play outside with friends to allow them to fully reap the benefits of an active lifestyle from a young age.

Clinical comprehensive of microfracture, autologous chondrocyte implantation, and periosteum-covered iliac bone grafting for Hepple stage IV-V lesions.

Chronic ankle pain significantly impairs daily activities and athletic performance with osteochondral lesions of the talus (OLT) in Hepple stages IV and V, which are often causative factors. This study aimed to assess the efficacy and safety of autologous osteochondral transplantation (AOT) for the treatment of these conditions. This retrospective study was conducted from May 2020 to May 2023 at Cangzhou Traditional Chinese and Western Medicine Combined Hospital, including patients with a diagnosis of Hepple stage IV or V OLT confirmed by magnetic resonance imaging (MRI) and arthroscopy. Surgical interventions involved arthroscopic debridement, followed by AOT or limited arthrotomy based on the location and size of the lesion. Preoperative and postoperative evaluations used the Visual Analog Scale, American Orthopedic Foot and Ankle Society Ankle-Hindfoot Scale, MRI-Based Cartilage Repair Tissue Scoring, and the International Knee Documentation Committee Knee Evaluation Form. Statistical analysis was conducted using paired-sample t tests to compare the preoperative and postoperative data. Twenty patients were included, revealing significant postoperative improvements in Visual Analog Scale, American Orthopedic Foot and Ankle Society, and MRI-based cartilage repair tissue scores (P < .05). The radiographic findings suggested effective cartilage regeneration. No adverse effects were observed in the donor knee sites, as confirmed by the stable pre- and postoperative International Knee Documentation Committee Knee Evaluation Form scores. Recovery of physical abilities was achieved on average within 7.3 weeks for daily activities and 13.4 weeks for sports activities. AOT effectively treats Hepple stage IV-V OLT, improves ankle function, promotes cartilage regrowth, and allows quick resumption of daily and athletic activities without compromising donor-site integrity.

Long-Term Performance of Subcutaneous Implantable Defibrillators in Athletes: A Multicenter, Real-World Analysis of Sport Activities from the iSUSI Registry

BackgroundNo data regarding subcutaneous-implantable cardioverter defibrillator (S-ICD) technology in patients actively engaging in sports activities are available. ObjectiveThis study aims to compare S-ICD performance between athletes and nonathletes. MethodsThe primary outcome of the study was the comparison of overall device-related complications between athletes and nonathletes. Appropriate shocks, inappropriate shocks, and individual device-related complications were secondary outcomes. ResultsA total of 1493 patients were extracted from the International Subcutaneous Implantable Cardioverter Defibrillator Registry (iSUSI) registry, of whom 152 (10.2%) were athletes, mostly engaging in dynamic sports (54.2%). Brugada syndrome, myocarditis, and arrhythmogenic right ventricular cardiomyopathy (ARVC) were more common in athletes (11.2% vs 3.3%, P < .001; 19.1% vs 9.0%, P < .001; 8.6% vs 2.8%, P < .001, respectively). During a median follow-up time of 25.5 (12.0–41.2) months, athletes were more likely to experience appropriate shocks (yearly rate: 7.2 [4.9–10.7] % vs 4.3 [3.6–5.1] %, P = .028), occurring more frequently during exercise (3.9% vs 0.6%, P < .001). This finding lost significance when adjusting for confounders (adjusted hazard ratio [aHR] 1.440 [0.909–2.281], P = .120). No differences were found in overall device-related complications (yearly rate: 3.3% vs 3.4%, P = .448) and inappropriate shocks (yearly rate: 5.3% vs 3.7%, P = 0.111). Myopotential oversensing (4.0% vs 1.3%, P = .011) was more common in athletes, as were lead infections (3.3% vs 0.9%, P =.008), with the latter clustering in the early postimplantation period. ConclusionThe S-ICD is a valid therapeutic option for preventing sudden cardiac death in athletes. Sports practice was not associated with an increased risk of complications or inappropriate shocks, although athletes are exposed to a higher risk of S-ICD infections in the early postoperative period.

Experimental Evaluation of Damping and Stiffness in Optimized Active Sport Utility Vehicle Suspension Systems

On a flat city road, the specificity of the suspension poses a challenge. Sport utility vehicles (SUVs) have less flexibility compared to regular cars, despite providing a firm grip on asphalt and concrete. Constant adjustments to the center of gravity of SUVs are necessary. Surprisingly, they are less reliable and stable in urban settings due to this characteristic. In this study, a mathematical model of the suspension system of SUVs based on the Newtonian approach is introduced and validated with data from experiments carried out by the MTS machine system on the mono-tube (oil/air) mixed damper element. The model accurately predicts the performance of this damper, commonly used in SUVs, across various operating conditions, including different frequencies. A coil spring element, serving as a passive suspension unit with this damper, is also tested experimentally under similar conditions. By integrating passive suspension elements with the active actuator, the proposed modified design reduces the power consumption needed for the actuator to function and ensures a certain level of reliability. The effectiveness and performance of the modified active suspension system in comparison to the traditional passive suspension system are assessed using three different strategies: hybrid PID-LQR, linear quadratic regulator (LQR), and proportional-integral-derivative (PID). The genetic algorithm is utilized to determine the optimal parameter values for each controller by minimizing a cost function, maximizing performance, and minimizing energy consumption. Simulation results demonstrate that the active suspension system controlled by the PID-LQR controller offers significantly improved ride comfort and vehicle stability compared to other systems. This suggests that the performance of the active suspension system is greatly enhanced by the combined application of the hybrid PID-LQR controller compared to other systems.

What Are the Factors Associated With Revision Surgery on the Residual Limb and Functional Results in Patients With Posttraumatic Lower Limb Amputations?

Lower limb amputations performed after trauma are associated with a high risk of revision surgery. While the factors influencing revision surgery in the upper limbs have been studied, no studies have analyzed these factors in the lower limbs. Existing explanations for these revision surgeries are unclear, often leaving patients uninformed. Surgeons also lack the tools to explain the factors that influence repeat operations to patients. Therefore, the aim of this study was to provide surgeons with some answers so they can inform their patients undergoing posttraumatic lower limb amputation, whether military or civilian. (1) What was the survivorship of the initial amputation free from any revision surgery? (2) What patient- and injury-related factors were associated with revision amputation? (3) Do these factors influence functional outcomes in these patients? A single-center, retrospective study was conducted between January 2010 and February 2020 on patients who had undergone traumatic lower limb amputation. Between January 2010 and February 2020, 322 patients underwent amputation or were followed up at Percy Military University Hospital. Thirty-one patients had undergone amputation at another center, 178 had undergone amputation for nontraumatic reasons, and 27 patients had only upper limb amputations. Of those remaining, 1 died before 6 months, and 6% (5 of 86) were not fitted with a prosthesis, leaving 99% (85 of 86) for survivorship free from revision analysis and 93% (80 of 86) for functional endpoints analysis in this retrospective study at a median of 6.5 years (IQR 5 to 9) following the index amputation. The median age at the time of amputation was 31 years (IQR 26 to 52), 85% (72 of 85) of patients were men, and 31% (26 of 85) were military personnel. Revision surgery was defined as surgery performed at or after 6 months to ensure that the residual limb was healed and fitted with a prosthesis. Revision procedures performed before 6 months (median 2 [IQR 0 to 7]) were considered as part of the initial residual limb formation surgery. We performed Kaplan-Meier survivorship analysis for the time free from revision amputation from 6 months after amputation. We considered the competitive risk of death using a Fine-Gray model by an ascending stepwise procedure. To answer our third research question, we performed a chart review and assessed patients' use of prostheses and assistive devices and the percentage of patients who returned to work. An ordinal logistic regression was used to analyze the factors influencing functional outcome using an ascending stepwise procedure. A total of 85 patients (94 limbs) were included, of whom 25 (27 limbs) underwent a revision surgery on the residual limb > 6 months after amputation. Kaplan-Meier survival estimates indicated that 5 years after the initial amputation 64% (95% confidence interval 53% to 77%) of the patients remained free from revision surgery on their residual limb. Factors associated with increased odds of revision amputation were smoking (subdistribution HR 2.6 [95% CI 1.2 to 5.8]; p = 0.02) and an age of > 50 years (subdistribution HR 0.3 [95% CI 0.1 to 0.8]; p = 0.01). Ninety-four percent (80 of 85) of patients were fitted with prostheses, and 40% (32 of 80) of patients used material or human assistance for simple activities of daily living. Seventy-one percent of patients (57 of 80) had returned to work. Ordinal logistic regression revealed an association between preinjury sports activity and the absence of need for assistance in daily activities (OR 9 [95% CI 2.9 to 31.8]; p < 0.001). Smoking appeared to be an associated risk factor for residual limb revision surgery in posttraumatic lower limb amputations and is potentially modifiable. Being at least 50 years of age seemed to be associated with a lower incidence of revision surgery, which is probably linked to lower functional demands made on limbs beyond this age. Our study showed a remarkable rate of fitting with a prosthetic device, with an improved functional result if the patient was athletic before the trauma. These results provide more precise information on the care pathway to be considered for each patient. A study with a much larger sample would make it possible to assess the risk factors for the occurrence of each complication involving revision surgery. Level III, therapeutic study.

Psychological well-being and healthy personality in sports practice

This study investigates the relationship between sports practice, psychological well-being, and personality traits. It involved 761 participants from Spain (80.6%) and Argentina (19.4%), comprising 37.1% men and 62.9% women, with a mean age of 20.4 years (SD: 7.5). Among them, 70.8% engaged in regular sports activities, contrasting with 29.2% who did not. The Scales of Psychological Well-being and the NEO-FFI were the assessment instruments chosen in order to measure psychological well-being and personality traits. Data analysis consisted of Student's t-tests and multiple linear regression models. The results reveal higher scores in five of six psychological well-being dimensions and healthier personality traits among subjects that engage in sports practice. Noteworthy enhancements were found in Self-acceptance, Autonomy, Environmental Mastery, Personal Growth, and Life Purpose for sports participants. Personality traits significantly mediate between sports practice and psychological well-being dimensions. Extraversion, Openness, and Conscientiousness correlate positively with well-being dimensions, while Neuroticism negatively impacts several aspects. Keywords: Sports practice, psychological well-being, athlete well-being, sport psychology, exercise psychology, personality traits, Big Five Model.

Oxygen Consumption, Ventilatory Thresholds, and Work Zones in Nordic Walking Competitors.

Background: Nordic walking (NW) is a physical sports activity that has been sufficiently studied from the point of view of health, but physiological and performance analyses have not been so much. Objectives: With this study, we intend to analyse the physical work areas, according to ventilatory thresholds, that occur during a NW competition. Methods: Four participants of different characteristics anthropometrics (weight 57.6-85.6 kg; height 165.8-178 cm; and fat percentage 14.5-21.5%) gender (3 males and 1 female) and age (15-57 years) who participated in the NW regional championship have been chosen, and their electrocardiographic tracing was recorded using a NUUBO® device throughout the race, obtaining average and maximum heart rates (HR) in eight sections of the circuit. Previously, in the laboratory, a maximal stress test was performed to determine the maximum oxygen consumption (VO2max), the first (VT1) and second (VT2) ventilatory threshold (VT). With these data, four work areas were obtained. Results: Most of the sections of the circuit were conducted with average HRs in zone 2a (above average between VT1 and VT2 but below VT2) and peak HRs in zone 3 (between VT2 and VO2max). Conclusions: We conclude that, with the data collected on HR, VO2max, and VT, the training zones obtained can be related to the heart rates in the different sections of the circuit. This can be used to improve the sports performance of the walkers.

This study explores the problems and strategies in modern physical education around the issue of improving students' sports participation. By analyzing factors such as outdated teaching methods, single curriculum design, imperfect evaluation mechanism, insufficient school sports culture atmosphere, and lack of social and family support, the reasons for the low level of students' sports participation are deeply analyzed. The study emphasizes that physical education is not only a means to improve physical fitness, but also an important way to promote students' mental health and cultivate social interaction skills. On this basis, the study proposes specific strategies such as improving teaching methods, optimizing curriculum design, strengthening school sports culture construction, providing diversified sports projects, and family and social support. Through multi-dimensional methods such as gamification teaching, stratified teaching, ability grouping, interest-driven, interdisciplinary integration, and family and community resource sharing, students' participation in sports activities can be effectively improved, thereby improving the effectiveness of physical education. The study pointed out that the purpose of physical education is to help students develop comprehensively in terms of physical fitness, psychological and social abilities through scientific teaching and management, and promote the improvement of their comprehensive quality.

Physical education and sport activity assessment tool-based machine learning predictive analysis for planification of training sessions

Background and purpose The aim of this study is to incorporte machine learning techniques in physical education activities assessment so we can plan a training session and learning cycle based on predictive analyses using machine learning algorithms. Material and methods A dataset represent the collection of physical tests (as Harvard test, Vertical and Horizontal Trigger) and activities performance (as 600 m, 1000 m, 12 min cooper) of 600 students in a secondary high school, aged between 15 and 20 years old (mean:16,21, SD:0,92), during 2021-2022 scholar year and project the predicted results on the following learning cycles in the scholar year of 2022-2023. We used Microsoft Azure Machine Learning Studio to obtain the best predictive model based on R2 score as an evaluating metric. Results Even if we focus on one metric test (as a target) with numeric values in this article, the results were promising compared to the predicted values of both physical tests and athletic performances, where we noticed some students have exceeded the expected values to reach. And the predictive analysis unveiled the more important features impacting the predicted results for the physical test. Conclusions Incorporating the Machine Learning techniques may encourage the change in the way we teach physical education and sport activities; otherwise, the assessment based on ML techniques will give a different overview on how to start a learning cycle and follow it up. The obtained predictive model provides an explication of the most impacting features on students’ performance allowing any training planification to relay on their importance respectively based on their density that affects prediction.

Sport and physical activities: actual Ukraine’s strategic narrative (in terms of encyclopedias)

Background and purpose Outline the importance of sports encyclopedias as a form of spreading and promoting a healthy lifestyle and popularizing high-achieving sports for the social and humanitarian development of Ukraine. Material and methods In the article, the primary used research methods are overview and descriptive analysis (an overview of academic publications indexed in Scopus, PubMed, Google Scholar, and National Library of Ukraine, as well as data on Ukrainian encyclopedias from the Corpus of Ukrainian Encyclopedias). This is a basis for descriptive analysis the capability of sports activities to improve the physical and mental (emotional, moral-volitional) resilience of the Ukraine’s population during wartime difficulty, the overall health level of the nation, and the demographic and accordingly economic situation in the country. Additionally, based on descriptive analysis, the potential of encyclopedias on sports and athletes in promoting a healthy lifestyle and physical activities among the population is examined). Reflection method is also used: authors offer a vision of how encyclopedic knowledge about sports and athletes should be structured to help improve the nation’s health, demographic, and economic situations, and thus resistance to Russian aggression). Results The war in Ukraine significantly damages the population’s health, adversely affecting the demographic and economic situation in the country. As a result, state humanitarian policy must focus on finding ways to counter these threats and emerging from this crisis. The article emphasizes that targeted, systematic development of sports and physical culture should be among the state policy priorities, as sports and physical activities improve population health. Authors show that promoting physical culture and a healthy lifestyle is crucial in this process, necessitating the studying of various information sources that can disseminate sports relevant knowledge and identifying the most effective ones. Conclusions Based on extensive justifications, the article proposes the idea of creating a Ukrainian sports encyclopedia as a means of promoting a healthy lifestyle among the Ukrainians, particularly essential in the post-war period. This would contribute to Ukraine's restoration by improving its demographic, socio-economic situation, and encouraging the return of Ukrainian refugees. The potential of a sports encyclopedia lies in highlighting and popularizing distinguished athletes who have achieved success and are respected globally, serving as role models, especially for the young generation of the country. The encyclopedic promotion of famous Ukrainian athletes is considered an effective mechanism for fostering a healthy lifestyle and patriotic feelings among Ukrainian citizens. The preparation of such a publication should rely on global encyclopedic-biographical experience, modern information technologies, and academic knowledge.

Effects of Pathological Characteristics on Functional Scores and Surgical Satisfaction in Patients after Hallux Valgus Surgery.

Few studies have explored the relationship between the pathological characteristics of hallux valgus and surgical outcomes. The aim of our study was to report the influence of pathological characteristics such as the tibial sesamoid position (TSP) and first metatarsal pronation on postoperative functional scores and patient satisfaction with hallux valgus surgery. From June 2017 to December 2022, a retrospective analysis was conducted on patients who underwent hallux valgus surgery at our hospital. Anteroposterior (AP) x-ray parameters (hallux valgus angle [HVA], intermetatarsal angle [IMA], distal metatarsal articular angle [DMAA], TSP, first metatarsal pronation, and first metatarsophalangeal joint dislocation) (preoperative weight-bearing, immediate postoperative non-weight-bearing, and early postoperative weight-bearing), visual analog scale (VAS) scores, American Orthopaedic Foot and Ankle Society (AOFAS) forefoot scores, SAFE-Q self-administered foot evaluation questionnaire (excluding the Sports Activity subscale), complications, and patient satisfaction were used to describe the outcomes. Correlation analysis and multiple linear regression models were used to identify factors influencing postoperative functional scores and patient satisfaction after hallux valgus surgery. Eighty-one patients (92 feet) whose early radiographic parameters and latest follow-up scores improved significantly (p < 0.01) were included in the present study. The overall complication rate was 27.2%, with recurrence being the most common complication (20.7%). Functional scores and patient satisfaction were associated with age; preoperative, immediate postoperative, and early postoperative HVA; and immediate postoperative IMA (p < 0.05), but not with TSP, first metatarsal pronation, DMAA, callosities, toe deformities, or first metatarsophalangeal joint dislocation (p > 0.05). The R2 values of the multiple linear regression models predicting postoperative functional scores and patient satisfaction ranged from 0.042 to 0.351. TSP and first metatarsal pronation were unrelated to postoperative functional scores or patient satisfaction. This finding enhances surgeons' understanding of the functional prognosis of hallux valgus surgery, particularly aiding in explaining the condition and assessing surgical outcomes.

The impact of moderate-intensity basketball intervention on the physical self-esteem and school adjustment of first-year high school students.

This study conducted an 8-week experiment with the basketball sports intervention program to explore the relationship between the basketball sports intervention program and the physical self-esteem and school adjustment of first-year high school students, providing references for first-year high school students' school adjustment and related research. Using convenient sampling,88 students in two classes of grade one in a senior high school in Changzhou were selected as the experimental research objects and were randomly divided into experimental groups (basketball) 44 people (20 male and 24 female; control group routine physical education) 44 people (23 male and 21 female). The exercise intervention lasted 8-week, 3-times-a-week with about 30 minutes of moderate-intensity exercise each time. The control group had normal sports activities, and the exercise intensity was not monitored. The Physical Self-esteem Scale and the School Adaptation Scale were used to measure the data in a group manner before and after the experiment. All data were statistically analyzed with SPSS26.0. (1) After 8 weeks of basketball intervention, the post-test level of school adaptation of first-year high school students was significantly higher than the pre-test (p<0.01), and the post-test level of physical self-esteem was significantly higher than the pre-test (p<0.01). (2) Basketball intervention can directly affect the school adaptation of first-year high school students and indirectly affect the school adaptation through physical self-esteem. The direct effect was 86.79%, and the indirect effect was 13.21%. (1) Intervention of moderate intensity basketball can improve first-year high school students' school adaptation and physical self-esteem. (2) Intervention of moderate intensity basketball can directly improve first-year high school students' and school adaptation by improving individual physical self-esteem. Physical self-esteem plays a partial intermediary role between basketball and school adaptation.

The association between insomnia and musculoskeletal problems in employees of an automotive company in Tehran, Iran

ObjectivesThe purpose of this study was to examine the association between insomnia and the number of pain areas among employees of an automotive company. Secondary aim was to examine the association between depression, anxiety, and stress, and musculoskeletal pain independent of insomnia. Material and methodsWe performed a cross-sectional study conducted in an automobile manufacturing factory. To collect data, we used the Nordic Musculoskeletal Questionnaire, ISI (Insomnia Severity Index), and DASS-21 (Depression, Anxiety, and Stress Scale). The univariate and multiple association analyses were performed using ordinal logistic regression adjusted for gender, age, industrial/non-industrial, sport activity, pack year, educational level, years of employment, anxiety, stress, and depression. ResultIn individuals with insomnia, the lower back was the most common area where pain was reported (59.5%). In all areas, pain symptoms were significantly more prevalent in individuals with insomnia compared to those without insomnia. Insomnia was associated with having pain with an increased odds of number of pain sites (odds ratio [OR] 2.81,95%CI 2.34–3.39). In ordinal logistic regression, there was an association between insomnia and pain, independent of the effects of depression, anxiety, and stress (OR 2.21,95%CI 1.52–3.23). DiscussionInsomnia was associated with pain in all regions of the body and a higher prevalence of pain in multiple areas. The insomnia-pain association was independent of depression, anxiety, and stress.

Rethinking Cultural Ecosystem Services in Urban Forest Parks: An Analysis of Citizens’ Physical Activities Based on Social Media Data

Urban forest parks play a vital role in promoting physical activities (PAs) and providing cultural ecosystem services (CESs) that enhance citizens’ well-being. This study aims to reevaluate CESs by focusing on the physical activity experiences of park visitors to optimize park management and enhance citizen satisfaction. This study utilized social media data and employed natural language processing techniques and text analysis tools to examine experiences related to physical activities in Beijing Olympic Forest Park, Xishan Forest Park, and Beigong Forest Park. A specialized sports activity dictionary was developed to filter and analyze comments related to PA, emphasizing the impact of natural environments on enjoyment and participation in PA. The importance–performance analysis (IPA) method was used to assess the service characteristics of each park. The findings reveal that urban forest parks are highly valued by citizens, particularly for their natural landscapes, leisure activities, and the emotional fulfillment derived from PA, with 82.58% of comments expressing positive sentiments. Notably, appreciation for natural landscapes was exceptionally high, as evidenced by the frequent mentions of key terms such as ‘scenery’ (mentioned 2871 times), ‘autumn’ (mentioned 2314 times), and ‘forest’ (mentioned 1439 times), which significantly influence park usage. However, 17.11% of the reviews highlighted dissatisfaction, primarily with the management of facilities and services during sports and cultural activities. These insights underscore the need for performance improvements in ecological environments and sports facilities. This study provides a novel perspective on assessing and optimizing urban forest parks’ functions, particularly in supporting active physical engagement. The rich CESs offered by these parks enhance physical activity experiences and overall satisfaction. The findings offer strategic insights for park managers to better meet citizens’ needs and improve park functionality.

Psychological Well-Being of Young Athletes with Physical Disabilities: A Systematic Review.

Currently, young people with disabilities practice less sport than people without disabilities, which is a risk to their health and affects their well-being. The aim of this research was to identify the specific dimensions and tools used to measure psychological well-being (PWB) in young athletes with physical disabilities and to analyze the influence of sport. A systematic review was conducted using PUBMED/MEDLINE, Web of Science, Scopus, and Sportdiscus databases, and the search was completed without limitation to any specific year, including results up to and including 29 May, 2023. A total of 2112 articles were obtained in the initial search. Eligibility criteria were: (i) athletes with a physical disability, (ii) performing adapted and non-adapted physical activity and/or sport, (iii) the study aimed to analyse well-being, and (iv) outcomes of psychological well-being variables were identified. Exclusion criteria were (i) people with injury or transient difficulty, (ii) rehabilitative physical activity, and (iii) the results did not show any psychological well-being variables or mentions. This review identified that the most used dimension was mastery of the environment, together with the autonomy. All studies showed a positive correlation between sport practice and psychological well-being.

An unusual Ogden type V tibial tubercle avulsion fracture: a case report and literature review

BackgroundOgden type V tibial tubercle avulsion fracture is an unusual type of physial injury. Thus, little is known about its mechanism of injury and treatment. The type of osteosynthesis is variable and depends on the experience of the surgeon. We commonly used cancellous screws fixation combined with tension band wiring for displaced fracture of the anterior tibial tuberosity.Case presentationThe present manuscript describes a case of a Han nationality 13-year-old boy who presented with severe pain of the left knee, which began after landing following a high jump. He had no significant past medical history apart from a high body mass index of 30.3. Radiographs revealed that he had an unusual Ogden type V tibial tubercle avulsion fracture. He was treated by open reduction and combined fixation with cannulated screws and tension-band wiring. After 3 months, the fracture healed without any complications or knee symptoms with full range of motion. He underwent reoperation for symptomatic hardware, which was removed at 5 months after initial surgery, and returned to his prior level of sporting activity at 1 year follow-up.ConclusionOur case suggests that excellent functional outcome could be achievable by open reduction with the combination of internal fixation and tension-band wiring for Ogden type V tibial tubercle avulsion fracture. This type of osteosynthesis could not only achieve anatomical reduction and stable fixation for such fractures, but also avoid further damage to the proximal tibial epiphysis, which prevents serious complications, such difference in leg length.

The Effect of a Training Programme (Skill-Psychological) on the Psychological Fitness and Performance of some Offensive skills of Volleyball Players

Volleyball is a competitive sport activity characterized by a direct struggle between two teams: Volleyball is one of the competitive sports activities that are characterized by direct struggle between two teams, as it has become a lot of practice today and occupies a good position as it is at a high and beautiful level of performance, so there is a desire for those who practice it to appear integrated performance as it is a combination of many different skills, whether offensive or defensive. Hence the importance of the research lies in knowing the extent of the effect of a training programme (skill - psychological) on psychological fitness and performance of some offensive skills in volleyball players. The issue lies in the fact that the player faces difficulties and psychological pressures during the match and his inability to regulate and control his emotions and greatly affect his performance, so the researcher decided to study the effect of a training programme (skill-psychological) on the psychological fitness and performance of some offensive skills in volleyball players. The aim is to find out the effect of a training programme on psychological fitness and performance of some offensive skills. It is hypothesized that there are statistically significant differences between the results of the pre and post tests in psychological fitness and the performance of some offensive skills in the sample. The experimental approach was used. The sample was volleyball players. It used the appropriate methods, tools and devices for research and also used the scale and tests and conducted pre and post tests and the exploratory and main experiment and the number of units was 16 units, two units per week, and concluded that the training exercises (skill - psychological) have a clear impact on the psychological fitness of players.

Emergency services at sports places in Rio de Janeiro: intervention of the sports management, activity and tourism

Emergency services in sports environments are crucial to ensuring the safety of those participating. Although Rio de Janeiro boasts a large and varied number of sports facilities, little is known about the dynamics of care provided in these locations. The primary objective of this study was to analyze the emergency response data from sports environments attended by the Military Fire Brigade of the State of Rio de Janeiro (CBMERJ). Secondly, the study aimed to compare the factors associated with emergency care at sports facilities, identify the most common injury sites, infer the causes of these accidents, and observe the frequency of fatalities during sports activities. For this study, 615 data points from the first emergency rescue group (1GSE) of the Rio de Janeiro Military Fire Brigade were analyzed, divided into North (n = 215), South (n = 145), West (n = 214), and Central (n = 30) zones. The dependent variables were: gender, outcome types, care types, transport types, immobilization, care characterization, care strategy, death details, emergency occurrences, and injury distribution by region. The zones were compared using the Kruskal-Wallis test and Dunn’s post hoc analysis, with a significance level of p≤0.05. Statistical analysis revealed differences between the zones when comparing outcomes, with the northern zone showing higher values (~75%) of treated and removed victims compared to the western zone (60%). There were also differences between the zones in the type of care provided, where the northern zone showed higher values (~35%) of intermediate care compared to the western (~20%), southern (~25%), and central (%) zones. The type of transport used varied between zones, with the southern zone showing higher usage of rapid response vehicles (ASE L) than the northern and central regions. The analysis further revealed a difference in immobilization conditions, with the central zone showing a lower frequency (~20%) of immobilization, that is, a higher proportion of "other" outcomes compared to the northern (~40%), western (%), and southern (~50%) zones.

Hybrid Fixation for Large Unstable Juvenile Osteochondritis Dissecans Lesions: Midterm Results in Adolescent Patients With Completely or Partially Salvageable Progeny Fragment.

This study aimed to describe the midterm clinical and radiographic outcomes of a hybrid fixation technique (HFT) combining interfragmentary compression with screws and biological support provided by the osteochondral autograft transplantation system (OATS) for treating large unstable juvenile osteochondritis dissecans (JOCD) lesions involving the knee in patients aged ≤18 years. Thirteen patients (15 knees, 9 males) with unstable JOCD lesions in the knee underwent treatment. HFT was indicated for lesions that had a completely salvageable (N=10) or partially salvageable progeny fragment (N=5). Patients were evaluated at a minimum follow-up of 1 year. The mean age of the patients was 15.3 years (range, 11 to 18y), with 10 lesions involving the medial femoral condyle and 5 involving the lateral femoral condyle. The mean lesion area were 397.7mm2. The outcome measures included the Pedi-IKDC and Tegner activity scales. Radiographic evaluation consisted of assessing osteochondral graft integration using the MOCART score on MRI and determining the degree of osteoarthritis using the Kellgren-Lawrence system (KL). At a mean follow-up of 51 months (range, 12 to 143mo), the mean Pedi-IKDC and Tegner activity scale were 90.1±7.2 and 94.7±6.7 points, respectively. Patients with unilateral lesions resumed sports activities on average after 7.7 months (range, 6 to 12mo). All patients exhibited progeny fragment integration on MRI, with a mean MOCART score of 85±6.5 (range, 75 to 95). Radiographs indicated grade 1 KL joint space in 13 knees and grade 2 in 2 knees. At the last follow-up, 12 patients were asymptomatic, whereas 1 patient experienced occasional mild discomfort during intense physical activity. Six patients required additional surgery for hardware removal, and 1 patient underwent intra-articular loose body removal. The hybrid fixation technique showed promising outcomes in terms of fragment healing and midterm results for unstable JOCD lesions. These findings suggest that HFT can be considered a valid treatment option for large unstable lesions involving the femoral condyles of the knee in adolescents. Therapeutic study (level of evidence IV).
