Exploring the Epidemiology of Injuries in Athletes of the Olympic Winter Games: A Systematic Review and Meta-Analysis.

This study sought to provide a comprehensive assessment of the incidence of sports injuries among athletes participating in the Olympic Winter Games and to investigate contributing factors. We gathered injury data from athletes participating in the recent four Olympic Winter Games, incorporating details on the sports event, sex, injury location, and type. Through a meta-analysis, we calculated the injury incidence rates for each sport and examined the influence of sex and the type of sport on these incidence rates. Out of 11,197 registered athletes, we documented 1,304 sports injuries. The sports events with the highest injury rates were freestyle skiing, snowboarding, alpine skiing, bobsleigh, and ice hockey, with the most frequent injury locations being the knees, thoracic/lumbar/back regions, and the wrist/hand/fingers. Contusions, hematomas, and bruises were the most prevalent injuries, followed by strains (including muscle rupture, tearing, or tendon rupture) and sprains (covering dislocations, subluxations, and ligament ruptures). In the Olympic Winter Games, events such as freestyle skiing, snowboarding, alpine skiing, bobsleigh, and ice hockey pose a particularly high risk. Predominant injury sites include the knee, spine/back, and wrist and hand, with injuries ranging from contusions and hematomas to strains and sprains. For effective injury prevention, it is crucial to emphasize proper medical resource allocation, specialized training for medical personnel, and meticulous venue maintenance.

A Study of the Training Load of Chinese Men Cross-Country Skiers in the Winter Olympic / Un estudio de la carga de entrenamiento de los esquiadores de fondo chinos en los Juegos Olímpicos de Invierno

This study examines the training load and performance of Chinese male cross-country skiers in preparation for the 2022 Winter Olympics. The research aims to establish a solid foundation for organising training loads and managing competitive readiness in Chinese cross-country skiing competitions. The study used quantitative data from four Chinese male athletes during the preparation period for the Beijing Winter Olympic Games in 2021. The Garmin 945 heart rate monitor was used to observe and document the training load, including factors such as training content, duration, distance, intensity level, and timing. The index test method was employed to assess the athletes' blood index at biweekly intervals. The Chinese skiers underwent a general preparation period that lasted 164 days, a special preparation period that lasted 70 days, and a pre-competition period that lasted 26 days. The overall training volume exceeded that of world-class athletes, with a notable emphasis on terrestrial training. The prevalence of endurance training was lower in comparison to world-class athletes, with a greater emphasis on strength training. The training intensity exhibited a modest increase, with a distribution pattern of low, medium, and high levels of intensity. The frequency of training and land training declined from the general preparation period to the pre-competition period, while the frequency of snow training increased. The intensity of the competition arrangement during the special preparation period was heightened.(AU)

Managing Accident Prevention in Ski Resorts: Participants' Actual Velocities in Slow Zones.

Velocity is one of the main factors affecting the kinematic of snow sports' accidents and the severity of resulting injuries. The aims of the present study were to measure the actual maximum velocities attained by a sample of snow sports participants in slow zones, to compare them to the recommended velocity limits and to assess whether their velocities were in any way related to their personal characteristics and to environmental conditions. Data were drawn from a sample of 1023 recreational skiers and snowboarders during the 2021-2022 winter season at four ski resorts located in the Spanish Pyrenees. Maximum velocity measurements were taken by the authors with a radar speed gun whose precision had been previously validated. Bivariate analysis tests were used to compare the influence that personal characteristics and environmental conditions had on the participants' maximum velocities. Furthermore, a multivariate analysis was performed. The binary logistic regression was used to distinguish the categories of personal and environmental factors that have the highest probabilities of impact on different segments of velocity. As generally accepted, probability values were two-tailed, and values of 0.05 or less were regarded as statistically significant. Participants' mean measured maximum velocity (±SD) was 51.61 (±16.14) km/h. A vast majority of the participants in this study traveled in slow zones at actual maximum velocities well over the recommended limits. Multivariate analysis showed that modality and both environmental conditions (visibility and snow quality) were highly significant and can be used to explain the chances of an increase in velocity in slow zones. Further research is needed to investigate causal relationships between skiers and snowboarders' accidents, injuries and disrespect for velocity limits.

The Global Research Status and Trends in Ice and Snow Sports Injuries from 1995 to 2022: A Bibliometric and Visualized Analysis.

OBJECTIVE: The aim of the present study is to focus on the most popular winter sports programs, and to investigate the global research status and trends in sports-related injuries. METHODS: The Web of Science (WoS) Core Collection database was chosen as original data and used for extracting publications on ice and snow sports injuries on 18 February 2022. Articles published in English between 1995 to 2022 were selected for this study. RESULTS: Finally, for the topic search, a sum of 1605 articles were extracted and used for further analysis. The country and journal ranked first-in terms of total number, total citations and the highest H-index of publications-were the USA and American Journal of Sports Medicine, respectively. The affiliation with the most cited publications was the Norwegian School of Sport Sciences. The most influential first author with the most citations (2537 times), the greatest average citations per article (65.05 times) and the highest H-index (26) was Bahr R. Articles were divided into five main clusters based on keyword analysis: injuries study, head and neck damage study, risk study, therapy study and epidemiology study. Studies related to epidemiology and brain damage in ice and snow sports will continue to be research hot topics. CONCLUSIONS: In conclusion, our study indicates that the ice and snow sports injuries research domain is more prevalent in North America and Europe. This study contributes to a comprehensive understanding of ice and snow sports injuries and provides hotspot directions.

Effects of six weeks of sub-plateau cold environment training on physical functioning and athletic ability in elite parallel giant slalom snowboard athletes.

Background: Hypoxic and cold environments have been shown to improve the function and performance of athletes. However, it is unclear whether the combination of subalpine conditions and cold temperatures may have a greater effect. The present study aims to investigate the effects of 6 weeks of training in a sub-plateau cold environment on the physical function and athletic ability of elite parallel giant slalom snowboard athletes. Methods: Nine elite athletes (four males and five females) participated in the study. The athletes underwent 6 weeks of high intensity ski-specific technical training (150 min/session, six times/week) and medium-intensity physical training (120 min/session, six times/week) prior to the Beijing 2021 Winter Olympic Games test competition. The physiological and biochemical parameters were collected from elbow venous blood samples after each 2-week session to assess the athletes' physical functional status. The athletes' athletic ability was evaluated by measuring their maximal oxygen uptake, Wingate 30 s anaerobic capacity, 30 m sprint run, and race performance. Measurements were taken before and after participating in the training program for six weeks. The repeated measure ANOVA was used to test the overall differences of blood physiological and biochemical indicators. For indicators with significant time main effects, post-hoc tests were conducted using the least significant difference (LSD) method. The paired-samples t-test was used to analyze changes in athletic ability indicators before and after training. Results: (1) There was a significant overall time effect for red blood cells (RBC) and white blood cells (WBC) in males; there was also a significant effect on the percentage of lymphocytes (LY%), serum testosterone (T), and testosterone to cortisol ratio (T/C) in females (p < 0.001 - 0.015, η p 2 = 0 . 81 - 0 . 99 ). In addition, a significant time effect was also found for blood urea(BU), serum creatine kinase (CK), and serum cortisol levels in both male and female athletes (p = 0.001 - 0.029, η p 2 = 0 . 52 - 0 . 95 ). (2) BU and CK levels in males and LY% in females were all significantly higher at week 6 (p = 0.001 - 0.038), while WBC in males was significantly lower (p = 0.030). T and T/C were significantly lower in females at week 2 compared to pre-training (p = 0.007, 0.008, respectively), while cortisol (C) was significantly higher in males and females at weeks 2 and 4 (p (male) = 0.015, 0.004, respectively; p (female) = 0.024, 0.030, respectively). (3) There was a noticeable increase in relative maximal oxygen uptake, Wingate 30 s relative average anaerobic power, 30 m sprint run performance, and race performance in comparison to the pre-training measurements (p < 0.001 - 0.027). Conclusions: Six weeks of sub-plateau cold environment training may improve physical functioning and promote aerobic and anaerobic capacity for parallel giant slalom snowboard athletes. Furthermore, male athletes had a greater improvement of physical functioning and athletic ability when trained in sub-plateau cold environments.

Clinical characteristics of patients with snow sports trauma transported to a trauma care center: A retrospective observational study.

BACKGROUND: Snow sports are a popular recreational activity; however, the incidence of injury of snow sports can be high for skiers and snowboarders. Our hospital receives severe trauma cases from snow resorts and hospitals throughout the region. This study aimed to determine whether the risk of snow sports-related major trauma that requires emergency surgery under general anesthesia varies by the equipment and injury mechanism. METHODS: This retrospective cohort study included patients with snow sports trauma referred to Gifu University Hospital, Japan between November 2010 and March 2020. We analyzed the need for emergency operation under general anesthesia within 24 h using Fisher's exact test. We identified 106 patients: (1) 90 in the snowboarders' group and 16 in the skiers' group or (2) 46 in the fall after jumping group (jumping group), 27 in the collide with other people and obstacle group (collision group), and 33 in the fall during gliding group (gliding group). RESULTS: Snowboarders were nearly twice as likely as skiers to require emergency surgery under general anesthesia (44% vs. 25%; p = 0.236]. No significant associations were found between emergency surgery under general anesthesia and injury mechanism, but half of the patients in the jumping group required emergency surgery. CONCLUSIONS: Snowboard as equipment and falls after jumping as a mechanism of injury tended to be associated with emergency surgery under general anesthesia, with no significant differences. In order to provide adequate resources for snow sports trauma, the cause of the patient's injury is strongly related to the urgency of the condition, and transport to a trauma center should be actively considered. Further studies are warranted with respect to the effects of personal protective equipment and skill level.

Winter sport musculoskeletal injuries: epidemiology and factors predicting hospital admission.

INTRODUCTION: Participation in winter sports such as skiing, snowboarding and snowmobiling is associated with risk of musculoskeletal injury. The purpose of our study was to describe and quantify emergency department encounters associated with these sports. METHODS: The National Electronic Injury Surveillance System (NEISS) was queried for skiing-, snowboarding- and snowmobiling-related injuries from 2009 to 2018. Patient demographics and disposition data were collected from emergency department encounters. Descriptive statistics were utilized to describe the trends in injuries from each sport and factors associated with the sports-specific injuries. RESULTS: From 2009 to 2018, there were an estimated 156,353 injuries related to snowboarding, skiing, or snowmobiling. Estimated injury incidence per 100,000 people decreased over time for skiing (3.24-1.23), snowboarding (3.98-1.22,) and snowmobiling (0.71-0.22,). The most common injury location by sport was shoulder for skiing (29.6%), wrist for snowboarding (32.5%) and shoulder for snowmobiling (21.9%), with fractures being the most common diagnosis. Only 4.5% required admission to the hospital. Fracture or dislocation was associated with highest likelihood of hospital admission (OR 42.34; 95% CI 22.59-79.37). Snowmobiling injuries (OR 1.63; 95% CI 1.20-2.22) and white race (OR 1.42; 95% CI 1.17-1.72) were also both associated with increased risk of hospital admission. CONCLUSIONS: Upper extremity injuries, particularly those involving fractures, were more common than lower extremity injuries for all three sports, with the shoulder being the most common location of injury for skiing and snowmobiling. This study can serve as the foundation for future research in sports safety and health policy to continue the declining trend of musculoskeletal injuries in the future. LEVEL OF EVIDENCE: III.

Research on Application Experience Design of Ice and Snow Sports Equipment Based on Bee Colony Model.

Sports equipment is the key to the smooth development of ice and snow sports. With the rapid development of social economy and the improvement of people's living standards, the demand for ice and snow sports equipment is increasing day by day. This article presents an improved method based on the chaos theory and the bee colony algorithm to quantify the application experience design of ice and snow sports equipment and reduce the influence of uncertain factors on the design results. First, the chaos theory can establish the dataset of application experience design and analyze the discreteness of the set. According to the bee colony algorithm, the dataset is divided into several groups, and each group obtains the best application experience design by using the design optimization strategy. Finally, the results are mixed to obtain the final experience design results. Through MATLAB simulation analysis and verification, the improved bee colony model can improve the accuracy of application experience design of ice and snow sports equipment in an uncertain environment, shorten the overall design time, and meet the requirements of application experience design of different ice and snow sports equipment. Therefore, the model proposed in this paper is suitable for the application experience design of ice and snow sports equipment.

Helmet Use in Preventing Head Injuries in Bicycling, Snow Sports, and Other Recreational Activities and Sports.

Bicycling, snow sports, and other recreational activities and sports are important activities to keep children and youth active as part of a healthy lifestyle. These activities can be associated with serious and fatal head and facial injuries. Helmets, when worn correctly, are effective in decreasing head injuries and fatalities related to these activities. Legislation for helmet use is effective in increasing helmet use in children and, ultimately, in decreasing deaths and head and facial injuries. A multipronged strategy employing legislation, enforcement of laws, and medical clinicians and community programs is important for increasing helmet use to decrease deaths and injuries from recreational sports.

Helmet Use in Preventing Head Injuries in Bicycling, Snow Sports, and Other Recreational Activities and Sports.

Recreational activities and sports are a common and popular way for youth to enjoy physical activity; however, there are risks related to physical injury. Injuries can potentially result in death and long-term disability, especially from traumatic brain injury. Helmet use can significantly decrease the risk of fatal and nonfatal head injury, including severe traumatic brain injury and facial injuries when participating in recreational sports. The most robust evidence of helmet effectiveness has been demonstrated with bicycling and snow sports (eg, skiing, snowboarding). Despite this evidence, helmets are not worn consistently with all recreational sports. A multipronged approach is necessary to increase helmet use by children and youth participating in recreational sports. This approach includes legislation and enforcement, public educational campaigns, child education programs, and anticipatory guidance from clinicians. This policy statement guides clinicians, public health advocates, and policymakers on best practices for increasing helmet use in recreational sports, including bicycling and snow sports.

Consumer Group Identification Algorithm for Ice and Snow Sports.

As an important part of the modern sports industry system, the quality and level of its development are related to whether China's sports industry can successfully become a pillar industry of the national economy. Therefore, the development of the ice and snow sports industry is to promote the expansion of China's sports industry scale high quality development of the national economy and an important way to build sports power. Participative sports consumption is the most important part of sports consumption and the development of the sports industry. The sports industry separated from participative sports consumption is water without source and tree without roots, while participative sports consumption demand is the power source of participative sports consumption. At present, there is no systematic and complete research on participation sports consumption demand. In order to understand the causes and demand state of residents' participation sports consumption demand and provide entry points for enterprises to formulate marketing strategies, this study constructs an organic system with participation sports service products as consumption objects, centering on the demanding state of participation sports consumers. In the system, on the theory of supply and demand, under the guidance of consumption economics theory, adhere to the combination of theoretical research and empirical analysis, the combination of macroplanning and microdesign, the combination of qualitative analysis and quantitative analysis, through the empirical investigation and receipt collection of residents' participation sports consumption demand, the use of systematic analysis, literature method, and survey method, through mathematical analysis, and other research methods, the paper explores the main causes and demand conditions of residents' participation sports consumption demand in different consumption states and excavates the main causes and demand conditions of participating sports consumption demand in different consumption states under different sports levels.

Behavior in Avalanche Terrain: An Exploratory Study of Illegal Snowmobiling in Norway.

Snowmobilers make a grim and significant contribution to avalanche fatality statistics in Norway. However, there is limited knowledge on the behavior of this group in avalanche terrain and the factors influencing this behavior. Our study documents what snowmobilers do and not do in avalanche terrain, how their behavior relates to managing complex avalanche conditions and if there is a mismatch between avalanche competence, education and riding preferences. This ethnographic study observed snowmobiler tracks and thus avalanche terrain usage in Northern Norway during 2018 and 2019, supported by open-ended conversations with target group riders. Results show that high-marking lost popularity to technical riding, which seems to be perceived as safer despite increased exposure to complex avalanche terrain and conditions with persistent weak layers in the snowpack. The detected mismatch between preferences and avalanche knowledge/attitude will remain an obstacle to future accident prevention efforts unless behavioral changes are addressed. This study of a predominantly illegal activity sheds light on how to explore and observe hard-to-reach illegal activities and should be of interest to a wider audience from other research disciplines.

Sledding Accidents at a Level 1 Pediatric Trauma Center Between 2006 and 2016.

BACKGROUND: Sledding is not a risk-free winter sport. According to the US Consumer Product Safety Commission, there were an estimated 13,954 sledding accidents requiring medical care in 2010. However, specific information concerning pediatric injuries related to sledding is not well defined. OBJECTIVES: This study aimed to identify the most common types of injuries associated with sledding accidents and demographic factors related to risk of injury in pediatric patients, and to compare injuries associated with 2 different age groups and sexes. METHODS: This is a retrospective descriptive study of pediatric patients (<18 years of age) presenting to a regional level I pediatric trauma center secondary to a sledding injury between 2006 and 2016. Demographic information including sex, age, mechanism of injury, and injury severity score was captured and analyzed using descriptive statistics. RESULTS: There were 209 patients identified for 10 years. There were no mortalities. There were 85 patients with primary head injury, of which 82 (96.5%) were hospitalized and 33 (38.8%) required an intensive care unit (ICU) stay. Seventy-five patients primarily suffered from extremity injuries, of which 56 (74.6%) had lower extremity fractures requiring operative intervention. There was no difference in ICU or length of stay between younger children (0-11 years) and adolescents (12-18 years) or between male and female patients. CONCLUSIONS: Childhood sledding can result in a variety of significant injuries requiring surgical intervention and hospitalization. Children pulled on sleds behind motorized vehicles are at higher risk for more severe injuries resulting in a higher rate of ICU admission.

Sledding while towed behind motorized vehicles associates with more severe and lethal injuries☆.

INTRODUCTION: Our institution has recently experienced an increase in sledding-related injuries, particularly when towed behind motorized vehicles. The purpose of this study was to characterize injury severity and clinical outcomes between pediatric patients who sustain injuries owing to motorized sledding accidents to aid in injury prevention messaging. METHODS: This retrospective study queried all patients who presented with a sledding-related injury to a single ACS-verified Level 1 Pediatric Trauma Center located in the Southeastern United States between 01/2015 and 01/2022. Demographics, injury details, and clinical outcomes were compared between two groups: patients towed behind a motorized vehicle (MOTOR) and those who were not (GRAVITY). RESULTS: Of the 67 patients included in our analysis, 15 (22%) were in the MOTOR group. Patients in the MOTOR group presented with significantly higher injury severity (ISS) and lower Glasgow coma scale (GCS) scores. Additionally, patients in this MOTOR group more often received a blood transfusion and intubation, had longer intensive care and overall hospital lengths of stay, and incurred higher hospital costs. In a multivariate analysis, the use of a motorized vehicle to sled was independently associated with increased ISS (OR: 9.7, 95% CI 1.9-17.5; p = 0.02). Two deaths occurred after sledding while being towed behind a motorized vehicle. CONCLUSION: Children experiencing sledding accidents while being towed by motorized vehicles sustain significantly more severe injuries and require more intensive treatments that together lead to increased hospital costs. These findings provide the framework for community educational initiatives and injury prevention measures to mitigate risk among children engaged in sledding. LEVEL OF EVIDENCE: IV retrospective cohort study.

Analysis of Ice and Snow Path Planning System Based on MNN Algorithm.

Traditional ice and snow path planning methods still have internal environmental problems in intelligent path planning, such as weak innovation ability, imperfect management, long planning path, unreasonable security structure, and low degree of specialization. Therefore, more and more ice and snow sports lovers are eager to solve this problem. This paper designs a path planning method based on three-dimensional ice and snow model. The path planning method of moving snow and ice based on MNN (Multiclass Neural Networks) algorithm is studied from many aspects. MNN algorithm is used for comprehensive analysis and evaluation. The mobile phone provides data information on key nodes, air resistance, momentum change, ice and snow movement track, and so on. The results show that the ice and snow path planning system based on MNN algorithm designed in this paper has the advantages of high feasibility, high data accuracy, and good prediction effect and can effectively improve the efficiency of ice and snow path planning.

Injuries in Skating and Sledding Winter Sports: Patterns and Imaging Findings.

While skiing and snowboarding are amongst the most common winter sports, skating and sledding activities are also popular for competition or recreation. Related injuries following an acute trauma mainly involve head, spine, upper and lower limbs. For elite athletes, overuse injuries represent a significant burden. In skating, lesions can be related to boot structure and design. This article reviews epidemiology, patterns, and imaging findings of common injuries in ice skating, short track speed skating, curling, luge, bobsleigh, and skeleton.

[Das unterschätzte Verletzungsrisiko beim Freizeitschlittenfahren]. / Das unterschätzte Verletzungsrisiko beim Rodeln im Freizeitsport.

BACKGROUND: Sledding is generally considered to be a relatively harmless winter leisure activity. The increased incidence of injuries, some of them severe, in our emergency department in the catchment area of several sledding slopes prompted an analysis of this patient population with respect to frequency and severity of injuries. PATIENTS AND METHODS: Based on the hospital documentation system, a retrospective evaluation of all emergency department visits in the winters 2016-2019 was performed. The words "sled", "sledge", "bob", "sledding", "sleighing", "sledging" were used as keywords, and the recorded data were analyzed with respect to outpatient treatment, inpatient treatment, inpatient treatment days, treatment days in the intensive care unit, number of necessary operations, injury patterns, and injury severity. RESULTS: A total of 175 injured patients were recorded over the 3­year period. In 94 patients (54%) the injury was classified as mild, 70 patients (40%) required inpatient treatment with an average length of stay of 8 days, resulting in a total of 590 inpatient treatment days. Surgical treatment was given to 49 (28%) of the injured with a total of 66 operations, 81 patients suffered from severe injuries up to multiple trauma with an injury severity score (ISS) of 34. DISCUSSION: The study demonstrates that sledding has a significantly higher injury potential than generally assumed and that the resulting costs and consequences of accidents are relevant. Especially on the designated sledge slopes, an increase in safety standards could be achieved through appropriate measures and rules.

Optimizing the regulation and control of sports injury and fatigue of winter olympic ice and snow athletes based on injury prevention / Otimização da regulação e controle de lesões esportivas e fadiga de atletas do gelo e da neve nos jogos olímpicos de inverno com base na prevenção de lesões / Optimización del control de lesiones deportivas y fatiga de los atletas de hielo y nieve en los juegos olímpicos de invierno basada en la prevención de lesiones deportivas

ABSTRACT This study reveals the characteristics and relationship of sports injury and fatigue of the Winter Olympics athletes, and monitors the athletes' psychological condition through case analysis of excellent athletes, and provides empirical evidence for athletes' psychological training and preparation for the physical and mental health services of Winter Olympics. Through questionnaires, literature review and other methods to study the injury situation of Winter Olympics ice and snow athletes, the results show that the proportion of chronic lumbar and knee joint injuries, and repeated muscle strains of Chinese Winter Olympics ice and snow athletes is large, and the cure rate is not high. The preparation activities are neither paid enough attention or sufficient, and the rationality of training plan arrangement is insufficient. The main cause of injury is insufficient understanding of the mechanism of injury and illness among athletes and coaches. Individual elite athletes need to improve their coping skills and pay attention to their psychological fatigue. In view of the sports' psychological characteristics and the problems faced by winter athletes, personalized psychological intervention programs should be formulated.

RESUMO O presente estudo revela as características e a relação de lesões desportivas e fadiga de atletas participantes dos Jogos Olímpicos de Inverno, e monitora as condições psicológicas dos atletas através da análise de casos de atletas de alto desempenho, além de apresentar provas empíricas para o treino e a preparação psicológico dos atletas para os serviços de saúde física e mental dos Jogos de Inverno. Através de questionários, revisão de literatura e outros métodos de estudo das lesões que acometem os atletas dos Jogos Olímpicos de Inverno, em esportes que envolvem gelo e neve, os resultados mostram que é grande a proporção de lesões lombares crônicas, lesões articulares do joelho e recorrência de distensões musculares, e a taxa de cura não é alta. As atividades de preparação não são suficientemente consideradas e a racionalidade do plano de treinos é insuficiente. A principal causa de lesão é a falta de compreensão dos mecanismos que ocasionam lesões e enfermidades entre atletas e treinadores. Atletas individuais de elite precisam melhorar suas habilidades de enfrentamento e prestar atenção à sua fadiga psicológica. Tendo em conta as características psicológicas desportivas e os problemas existentes entre os atletas dos Jogos de Inverno, programas de intervenção psicológica personalizados devem ser formulados.
