Abstract
This case-control study aimed to analysis of the relationship between individual behaviours and sports risk factors and injuries among skiers and snowboarders. During the 2021-2022 winter season, 1132 injured and 1069 non-injured skiers and snowboarders were surveyed regarding demographic, self-reported individual behavioural and sporting characteristics. Multivariate regression analysis revealed previous snow-sports injury (OR: 26.39, 95% CI: 13.32-52.31, P < 0.001), nervousness (OR: 3.78, 95% CI: 2.91-4.90, P < 0.001), calm (OR: 1.90, 95% CI: 1.46-2.48, P < 0.001) and fearful (OR: 20.60, 95% CI: 11.45-37.04, P < 0.001) emotional states, and higher risk-taking behaviours (OR: 3.72, 95% CI: 2.87-4.83, P < 0.001) were important risk factors associated with injuries to all skiers and snowboarders. Compared to snowboarders, the risk of injury to skiers was more likely to increase as the length of their skiing experience increases. Emotional and cognitive levels appear to be important conditions that influence injuries to skiers and snowboarders, a proper understanding of the potential interactions between cognition and behaviour appears to be important for public ski safety management.

Abstract
Terrain parks (TP) are popular attractors to snowsport resorts for both skiers and snowboarders, however there is some concern about the risk of severe injury. TP risk management needs to balance the business case against the human cost of injury. To inform effective TP risk management strategies, it essential to understand risk factors, and injury frequency and severity. To this end, a retrospective inductive analysis of Canada West Ski Areas Association's Accident Analyzer database (2008-2009 to 2017-2018). Inclusion criteria., (i) at least 8 seasons of matching injury and participation data, (ii) minimum of 10 TP injuries p.a., (iii) activity either skiing or snowboarding, and (iv) injury location was coded as terrain park/rail. Data was excluded for ticket type N/A. Anonymised and deidentified secondary data was entered into SPSS for analysis. Between group differences were explored via χ2 analysis with Yates' Continuity Correction for 2 × 2 tables and an inductive data driven approach to explore other factors. From this data, 12,602 injuries were in TPs across 28 resorts. 11,940 (94.7%) met the inclusion criteria (14.2% female; 86.5% <25 years; 73.0% snowboarders. 50.8% were male snowboarders <25 years). Higher levels of helmet use were not correlated with a decline in reported head injuries. Day-ticket holders were more likely to be injured on their first two uses of a run than season pass holders. More snowboarders injured in TPs (59.7%) went to hospital than skiers (51.0%). Thus, participants injured in TP are typically younger, male, and snowboarders with either a Season Pass or day ticket, thus potentially a distinct target group for injury mitigation and prevention strategies and communications. The application of other frameworks such as the hierarchy of control and socioecological framework reflects the complex multifactorial systems in which snowsports occur and from which more targeted risk management strategies may emerge to mitigate injury risk while maintaining TP appeal.

Abstract
Introduction An anterior cruciate ligament (ACL) tear is a devastating injury for athletes that is predominantly low energy and non-contact in nature. ACL tears are one of the most well-researched injuries in sports, however, scant research has been done on competitive snowboarders. Boardercross is a relatively new sport introduced to the Winter Olympics in 2006. Initially, it entailed four snowboarders racing head-to-head down a course of obstacles in a race to the finish, with the top two riders advancing to the next rounds. It has since expanded to six racers traveling up to 60 mph and jumps up to 100 feet in length in a head-to-head race to the finish. This extreme sport puts its athletes at risk for serious injury, requiring investigation. Purpose Investigate the prevalence of ACL tears in the extreme sport of boardercross, evaluate sport-specific factors that may put athletes at higher risk, and report return to sport data. Methods An expedited IRB approval was obtained. A survey was distributed to athletes via e-mail to national/regional coaches of countries with competitive boardercross teams. Professional coaches distributed the survey and secondarily distributed it to athletes. Results Sixty-six competitive snowboardcross athletes responded to the email surveys 48.5% of respondents had torn their ACL at least once in their career. Of the female respondents, 55.6% suffered at least one ACL tear, and 43.6% of male respondents suffered at least one ACL tear. 31.2% suffered more than one ACL tear during their career. Of those who tore their ACL, 91.3% (p <0.001) tore their front leg. 100.0% of the respondent athletes returned to sport post-ACL reconstruction. Conclusion Professional boardercross racers are at a higher risk of tearing their ACL than other winter sport athletes, including alpine skiers. A predominance of ACL injuries occurred on the front leg during landing from an aerial maneuver. All respondent athletes returned to the sport after injury, with approximately half returning within six months. Although no statistical significance was achieved, the data provided trends on risk factors related to ACL injuries among snowboardcross athletes.

Abstract
There is a lack of reviews covering the topic of the parallel high prevalence of injuries in female winter sport elite athletes. We aimed to review the data on incidence and patterns of injuries in female athletes participating in official competitions of winter sports. We conducted a comprehensive literature search on epidemiological data and etiological information on alpine skiing, snowboarding, ski jumping and cross-country skiing. The most common location of injury was the knee among skiers and ski jumpers and the incidence of severe ACL events was 7.6 per 100 ski racers per season (95% CI 6.6 to 8.9) in female alpine skiers. Snowboarders and cross-country skiers were more affected in the ankle and the foot. The most common cause was contact trauma with stagnant objects. The injury risk factors include training volume, knee pre-injuries, the period of the season and the technical equipment. Females are at greater risk of suffering from overuse injuries during the competitive season, as opposed to male athletes who are more likely to suffer from traumatic injuries. Our findings can be used to inform coaches and athletes and to guide future injury prevention plans.

Abstract
To prevent spinal and back injuries in snowboarding, back protector devices (BPDs) have been increasingly used. The biomechanical knowledge for the BPD design and evaluation remains to be explored in snowboarding accident conditions. This study aims to evaluate back-to-snow impact conditions and the associated back injury mechanisms in typical snowboarding backward falls. A previously validated snowboarder multi-body model was first used to evaluate the impact zones on the back and the corresponding impact velocities in a total of 324 snowboarding backward falls. The biomechanical responses during back-to-snow impacts were then evaluated by applying the back-to-snow impact velocity to a full human body finite element model to fall on the snow ground of three levels of stiffness (soft, hard, and icy snow). The mean values of back-to-snow normal and tangential impact velocities were 2.4 m/s and 7.3 m/s with maximum values up to 4.8 m/s and 18.5 m/s. The lower spine had the highest normal impact velocity during snowboarding backward falls. The thoracic spine was found more likely to exceed the limits of flexion-extension range of motions than the lumbar spine during back-to-snow impacts, indicating a higher injury risk. On the hard and icy snow, rib cage and vertebral fractures were predicted at the costal cartilage and the posterior elements of the vertebrae. Despite the possible back injuries, the back-to-snow impact force was always lower than the force thresholds of the current BPD testing standard. The current work provides additional biomechanical knowledge for the future design of back protections for snowboarders.

Abstract
INTRODUCTION Skiing and snowboarding are popular winter sports with significant youth participation and inherent potential for injury. We investigated the relationship between age and injury characteristics exhibited by youth skiers and snowboarders. METHODS In this cross-sectional study, we investigated injury characteristics among youth skiers and snowboarders at a ski resort, examining the association between age and injury type. We compared injury characteristics among young children (aged 3-6 y), school-aged children (aged 7-14 y), and older adolescents (aged 15-17 y) using χ2, and examined predictive variables for injuries at different anatomical locations using logistic regression. RESULTS Compared with snowboarding, skiing was associated with greater odds of lower extremity (adjusted odds ratio [aOR]=6.8, 95% confidence interval [CI]: 4.89, 9.47, P<0.001) and head/face/neck (aOR=1.63, 95% CI: 1.20, 2.21, P=0.002) injuries. Compared with skiing, snowboarding was associated with greater odds of upper extremity injury (aOR=5.9, 95% CI: 4.6, 7.6, P<0.001). Age group significantly affected injury mechanism (χ2 [df=12, n=1129]=42.882, P<0.0001) and diagnosis (χ2 [df=12, n=1129]=43.093, P<0.0001). Young child skiers had the highest proportion of injuries to the head/neck/face and lower extremities and a significantly higher proportion of collision injuries and fractures than older skiers. Young child skiers most frequently injured the lower leg/ankle, while older skiers most frequently injured the knee. CONCLUSIONS Youth skiers exhibited predominately lower extremity injuries, while snowboarders exhibited predominately upper extremity injuries. Age significantly affected injury mechanism and injury diagnosis in youth skiers. Specifically, younger skiers tended to suffer more fractures and collision injuries than older youth skiers.

Abstract
BACKGROUND Acromioclavicular joint (ACJ) injuries are among the most common injuries in contact and non-contact sports. As winter sports become more popular, there has been an increase in shoulder injuries among recreational skiers and snowboarders. METHODS This was a retrospective analysis of all patients who presented to the Denver Health Winter Park Medical Center with ACJ injury from 2012 to 2017. We examined the incidence of ACJ injuries, the injury mechanism, demographics, and type of ACJ injuries among skiers and snowboarders treated at the clinic. RESULTS A total of 341 ACJ injuries (6.7% of total visits) were encountered during the study period. The majority of ACJ injures were type I (41.3%) and mainly occurred in men (86.5%). Most (96.8%) of the cases were primary ACJ injuries on the right shoulder (56.9%). The average age of patients with ACJ injuries was 30.0 years (range 10-72). More than half (62.2%) of ACJ injuries occurred while snowboarding. The most common mechanism of injury (93.5%) was fall to the snow while skiing/snowboarding. Women were more likely to have a type I ACJ injury than men (80.4% vs 35.4%; P < 0.001). Women with ACJ injuries were more likely to suffer the injury while skiing than snowboarding (71.7% vs 28.3%; P < 0.001), compared to men who were more likely to suffer the injury while snowboarding than skiing (67.5% vs 32.5%; P < 0.001). CONCLUSIONS Most of the ACJ injuries were type I and occurred mostly in men. Snowboarders were more likely to have an ACJ injury than skiers. LEVEL OF EVIDENCE Level IV, Epidemeiology Study.

Abstract
Aim To assess the rate of self-reported concussion in midwestern skiers and snowboarders. Patients Recreational skiers and snowboarders between the ages of 14 and 69 years during a single winter ski season (2020-2021) at a ski area in Wisconsin, USA. Methods Survey study. Results Among this survey population (n = 161), 9.32 and 19.25% reported one or more diagnosed concussion and suspected concussion respectively as a result of a skiing- or snowboarding-related incident. Skiers and snowboarders that self-identified as advanced, those who utilized terrain park features, and those that participated in freestyle competition had significantly higher self-reported rates of concussion. Conclusion Self-reported concussion history indicates a concussion prevalence that is higher than expected based on previous studies. Participants reported significantly more suspected concussions than diagnosed concussions, indicating a possible issue with underreporting in this population.

Abstract
This study investigated the effect of a new type of ear pads for ski helmets on the hearing performance of 13 young adults (mean age: 22 years). Free-field hearing thresholds and sound localization performance of the subjects were assessed in three conditions: without helmet, with a conventional helmet and with the modified helmet. Results showed that the modified helmet was superior to the conventional helmet in all respects, but did not allow for a performance level observed without a helmet. Considering the importance of precise hearing and sound localization during alpine skiing, acoustically improved ear pads of ski helmets, as demonstrated in this study, can essentially contribute to enhancing the safety on ski slopes.

Abstract
Background: The epidemiology of acute vertebral fractures (AVFs) sustained while skiing
and snowboarding remains poorly defined in the United States. Hypothesis: It was hypothesized that there would be no significant differences across sex
and a greater number of AVFs in younger age groups associated with skiing
and snowboarding. Study Design: Descriptive epidemiological study. Methods: The authors utilized the National Electronic Injury Surveillance System to
identify patients who were reported in emergency departments in the United
States from 2000 to 2019. All patients were noted to have sustained AVFs
during skiing or snowboarding. National estimates and demographic analysis
were performed. Results: A total of 466 AVFs were identified, or roughly 23.3 AVFs per year. Compared
with women, men accounted for the majority of AVFs sustained in both skiing
and snowboarding: 67.8% (95% CI, 62.6%-73.0%) during skiing and 82.1% (95%
CI, 76.3%-87.8%) during snowboarding. This represented a significantly
larger percentage of AVFs while snowboarding compared with skiing
(P = .002). Women accounted for 32.2% (95% CI,
27.0%-37.4%) of AVFs while skiing and 17.9% (95% CI, 12.2%-23.7%) while
snowboarding, which indicated a significantly larger percentage of AVFs
sustained during skiing compared with snowboarding (P =
.002). Snowboarders were more likely than skiers to sustain an AVF in the
region of the coccyx (21.5% [95% CI, 14.3%-28.7%] vs 11.5% [95% CI,
3.5%-16.9%], respectively; P = .003) and as a result of a
fall at ground level (69.2% [95% CI, 62.1%-76.4%] vs 52.8% [95% CI,
43.2%-62.4%], respectively; P = .009). A significant
decrease in the number of snowboarding-related AVFs was identified over the
20-year study period: 899 in 2000-2003 versus 283 in 2016-2019
(P < .01). The change in skiing-related AVFs over
the study period was not statistically significant (694 vs 462;
P = .5). Conclusion: This national study of AVFs sustained while skiing and snowboarding
identified critical sex- and age-specific differences in the population at
risk, anatomic location of injury, and mechanism of injury. The national
data generated from this study over a 20-year period may be utilized to
better inform public health injury awareness and prevention initiatives in
the rapidly growing sports of skiing and snowboarding.

Abstract
Study Design Retrospective descriptive observational study. Purpose Skiing and snowboarding offers valuable opportunities for outdoor physical activity throughout the cold winter months, but these activities can result in substantial personally injury. This study aimed to analyze trends in skiing and snowboarding-related facial trauma epidemiology. Methods The National Electronic Injury Surveillance System (NEISS) was queried for facial trauma related to skiing and snowboarding treated in United States (US) emergency departments between 2010 and 2019. These data and weighted estimates were used to analyze patient demographics, injury location, and etiology. Results A total of 361 skiing or snowboarding-related facial injuries were recorded. Lacerations were most common injury (165/361; 45.7%), and facial fractures occurred in 21.6% (78/261) of patients. The most common facial fracture locations are the nose (38/78; 48.7%), orbit (17/78; 21.8%), and mandible (15/78; 19.2%). Pediatric patients accounted for 52% (187/361) of these injuries and had higher rates of lacerations (51.9% vs 39.1%, P < 0.05) and hospital admission (4.8% vs 1.15%, P < 0.05) than adults. Adults had a higher rate of facial fracture (30% vs 13.9%, P < 0.001) than children. Conclusions Skiing and snowboarding-related facial trauma is relatively uncommon in the US. In general, these injuries are largely decreasing, but facial fractures still occur not infrequently during these activities. Based on our data, we strongly urge helmet manufacturers to increase the availability of recreational snowsport helmets that include nose, orbit, and mandible protections, which could help to prevent many of these injuries.

Abstract
Elite athletes achieve superior performance under high pressure in competitive situations. Although it is known that such situations affect the precompetitive activity of their autonomic nervous system (ANS), the relationship between precompetitive ANS activity and performance remains controversial. Especially in extreme sports, it has been shown that cardiac sympathetic tone occurs in athletes before competition attempts. However, the relationship between precompetitive sympathetic tone and performance is unclear. To investigate this relationship in extreme sports, we organized a freestyle snowboard jumping competition and examined competitors' physiological states and performance during this event. The electrocardiograms (ECGs) of 20 elite snowboarders were measured 10 min before each jump in different competitive situations: practice, qualifying, and final sessions. The mean heart rate (HR), the low-frequency to high-frequency component ratio (LF/HF ratio), the logarithm of the HF (lnHF) component of the frequency-domain of the heart rate variability (HRV), the ratio of the standard deviation of all R-R intervals to the root mean square of successive differences of R-R intervals (SDNN/rMSSD ratio), and the rMSSD of the time-domain of the HRV were calculated from the ECG data. The results showed a significant increase in the mean HR as well as significant decreases in the lnHF component and rMSSD of the HRV as the sessions progressed. Interestingly, the mean HR, LF/HF ratio and SDNN/rMSSD ratio of the HRV showed significant positive correlations with competitive scores, and the lnHF component and rMSSD of the HRV showed significant negative correlations with the scores. Our results indicate that precompetitive ANS activity becomes predominantly sympathetic in elite extreme athletes, such as freestyle snowboarders, when the competition intensifies, and that this sympathetic predominance is positively related to competitive performance.

Abstract
Background Although clavicle fractures are a common sports injury, there are limited studies on the incidence and causes of clavicle fractures among winter sports athletes. Purpose To evaluate the characteristics and injury mechanisms associated with clavicle fractures among patients evaluated at a Colorado ski resort. Study Design Descriptive epidemiology study. Methods This was a retrospective descriptive analysis of patients with clavicle fractures at the Denver Health Winter Park Medical Center during the 2012-2013 to 2016-2017 ski seasons. Chart review was performed on the patient cohort to confirm clavicle fracture diagnosis and to evaluate factors associated with clavicle fracture. Results A total of 393 clavicle fractures (6.2% of total clinic visits) occurred during the study period, corresponding to an overall clavicle fracture incidence of 8.4 per 100,000 participant-visits. The mean patient age was 26.4 years (range, 5-73 years). The majority were middle-third fractures (85.5%), occurring mainly in men (87.3%). More than half of the fractures were comminuted (54.5%) and occurred in snowboarders (55.0%). The most common mechanism of injury was a fall onto snow while skiing or snowboarding (92.4%). Women sustained more clavicle fractures while skiing compared with snowboarding (82.0% vs 18.0%; P < .001), while men sustained more fractures while snowboarding compared with skiing (60.3% vs 39.7%; P < .001). Conclusion Clavicle fractures are relatively common, but there are scant incidence data for clavicle fractures in mountain sports. Consistent with prior studies, clavicle fractures were more common in younger patients and men. The most common anatomic fracture location was the midclavicle. A greater proportion of clavicle fractures among men were sustained during snowboarding and among women during skiing.

Abstract
PURPOSE To determine and compare the incidence and severity of wrist fractures in skiers and snowboarders. METHODS A university-run orthopedic clinic at the base of a major ski resort has maintained an injury database spanning the years 1972 to 2012. Demographic information, equipment type, ability level, trail type and conditions, number of falls, circumstances surrounding the injury, and radiographs were collected on participants sustaining wrist fractures and compared with uninjured control participants asked the same questions, but in reference to their last fall where no injury resulted. A risk factor model for wrist fracture and severity in alpine sports was developed. RESULTS During the 40-year period, 679 wrist fractures were identified. The incidence of wrist fracture per 1,000 days was 0.447 in snowboarders and 0.024 in skiers. In comparison with a representative sample of uninjured skiers, bivariate analyses revealed that skiers who experienced fractures were less experienced, had a greater number of falls, were on green or double black trails, and were injured owing to jumping or other reason related to technique. A higher risk for fracture was found for beginners, males younger than age 16, women older than age 50, and 4 or fewer days skiing that season. Bivariate analyses found that injured snowboarders were more likely to be female, younger, less experienced and had received less instruction than uninjured snowboarders. Higher risk for wrist fracture among snowboarders was found to be associated with age younger than 18 and less experience. CONCLUSIONS Wrist fractures occur at an 18 times greater incidence in snowboarders than in skiers. Skiers with wrist fractures were beginners, males younger than 16, women older than 50, or those who had less participation. Snowboarders sustaining wrist fractures were younger than 18 or had less experience. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic III.

Abstract
Background There is limited knowledge regarding the incidence of recreational snowboarding-related spinal injuries. Objective This study investigated the incidence and characteristics of recent recreational snowboarding-related spinal injuries and discussed possible preventive measures to reduce the risk of spinal injuries. Methods This descriptive epidemiological study was conducted to investigate the incidence and characteristics of snowboarding-related spinal injuries at the Myoko ski resort in Niigata Prefecture, Japan, between 2006 and 2017. The incidence of spinal injuries was calculated as the total number of spinal injuries divided by the number of snowboarding visitors, which was estimated based on the ticket sales and estimates regarding the ratio of the number of skiers to the number of snowboarders reported by seven skiing facilities. Results In total, 124 (72.5%) males and 47 (27.5%) females suffered spinal injuries. The incidence of spinal injuries was 5.1 (95% CI 4.4 to 5.9) per 100 000 snowboarder visitors. Jumps at terrain parks were the most common factor in 113 (66.1%) spinal injuries, regardless of skill level (29/49 beginners, 78/112 intermediates, 6/10 experts). Overall, 11 (including 9 Frankel A) of 14 (78.6%) cases with residual neurologic deficits were involved with jumps. Conclusions In recreational snowboarding, jumping is one of the main causes for serious spinal injuries, regardless of skill level. The incidence of spinal injuries has not decreased over time. Individual efforts and educational interventions thus far have proven insufficient to reduce the incidence of spinal injury. Ski resorts and the ski industry should focus on designing fail-safe jump features to minimise the risk of serious spinal injury.

Abstract
The purpose of this study was to compare injury patterns between recreational skiers and snowboarders. Injured skiers (n = 3,961) and snowboarders (n = 2,428) presented to a mountainside medical clinic, 2012/13-2016/17. Variables investigated for analysis included demographics/characteristics, injury event information, and injury information. Skiers were older than snowboarders (34.3 ± 19.3 vs. 23.2 ± 10.5 years, p < 0.001); a greater proportion of skiers were female (46.3% vs. 27.8%, p < 0.001). Most skiers (84.4%) and snowboarders (84.5%) were helmeted at the time of injury (p = 0.93). Snowboarders were most frequently beginners (38.9%), skiers were intermediates (37.8%). Falls to snow (skiers = 72.3%, snowboarders = 84.8%) and collisions with natural objects (skiers = 9.7%, snowboarders = 7.4%) were common injury mechanisms. Common skiing injuries were knee sprains (20.5%) and head trauma (8.9%); common snowboarding injuries were wrist fractures (25.7%), shoulder separations (9.1%), and head trauma (9.0%). Given that injury patterns significantly differ between sports, it is important for clinicians, ski patrollers, and resorts to develop and deliver sport-specific injury prevention interventions to most effectively decrease injury burden.

Abstract
Understanding the structure and variability of motion is essential for sports technique development and an effective training design. Biomechanical analysis is particularly important in new disciplines with spatially complex motions, such as snowboarding. This study aimed to evaluate the level of variability of the kinematic variables in a single backside snowboard flip known as a “wildcat”. Forty-six correct flips performed by 7 experienced athletes (age: 24.9 ± 4.34 year; body mass: 71.6 ± 12.87 kg; body height: 177.4 ± 6.99 cm) were recorded using an optoelectronic VICON system in the controlled setting of an indoor freestyle park. Athletes were equipped with special boards with wheels and the geometry of the ramps corresponded to the actual on-snow conditions. The analysis revealed two distinct single flip strategies, which differed in the way the tuck position was sustained. For all the measured variables, the coefficient of variation was computed, which allowed to identify the athlete with the highest (average 45.3%) and lowest (average 20.5%) variability of kinematic variables. Moreover, it was shown that the lowest values of the coefficient of variation occurred at the end of the grouping phase (average 14%) and that among all the different variables, those related to the duration of motion were most unstable (average 63%, SD = 48.5%).

Abstract
Annually, millions of people engage in mountain sports activities all over the world. These activities are associated with health benefits, but concurrently with a risk for injury and death. Knowledge on death rates is considered important for the categorization of high-risk sports in literature and for the development of effective preventive measures. The death risk has been reported to vary across different mountain sports primarily practiced in the summer season. To complete the spectrum, the aim of the present review is to compare mortality rates across different mountain sports activities primarily practiced in winter. A comprehensive literature search was performed on the death risk (mortality) during such activities, i.e., alpine (downhill) skiing, snowboarding, cross-country skiing, ski touring, and sledging. With the exception of ski touring (4.4 deaths per 1 million exposure days), the mortality risk was low across different winter sports, with small activity-specific variation (0.3–0.8 deaths per 1 million exposure days). Traumatic (e.g., falls) and non-traumatic (e.g., cardiac death) incidents and avalanche burial in ski tourers were the predominant causes of death. Preventive measures include the improvement of sport-specific skills and fitness, the use of protective gear, well-targeted and intensive training programs concerning avalanche hazards, and sports-medical counseling for elderly and those with pre-existing diseases.

Abstract
Behavioral variables might play an important role in explaining the differences in injury rates across winter sport disciplines and injury prevention programs might be more specifically designed based on this knowledge. On ski slopes, alpine skiing, snowboarding, and ski touring are the predominant winter sport disciplines. Therefore, the aim of the present study was to investigate possible differences in injury-related behavioral variables between practitioners of these disciplines. Using a matched re-analysis approach of a cross-sectional survey, 414 winter sport participants (alpine skiers, snowboarders, ski tourers, each n = 138) were analyzed on the differences in sensation seeking, treated injuries, and injury-related behavioral variables. Cochran-Mantel-Haenszel and Friedman tests revealed significantly higher sensation seeking, p < 0.001, and a significantly higher percentage of participants reporting to have consumed alcohol in the past five skiing days, p = 0.006, in snowboarders compared to alpine skiers. The participants with treated injuries showed higher sensation seeking, p < 0.050, and a higher percentage of snowboarders, p = 0.020, compared to participants without treated injuries. Injury prevention programs for snowboarders, who remain an important risk group for injury prevention, might benefit from considering a possibly higher percentage of alcohol-consuming participants and from providing information on injury-related risks of sensation seeking.

Abstract
OBJECTIVE To synthesise the current evidence regarding the risk factors, the injury prevention strategies and the profile of injured skiers and snowboarders in terrain parks (TPs) and half-pipes (HPs). DESIGN Systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. DATA SOURCES Literature searches from six electronic databases and manual searches were performed. ELIGIBILITY CRITERIA FOR SELECTING STUDIES Inclusion criteria were: (1) publication based on original data; (2) injuries sustained in TPs or HPs; (3) recreational skiing or snowboarding injuries; (4) observational or experimental study design with a comparison group. RESULTS No study explored the risk factors in HPs or the prevention strategies in TPs or HPs. From the literature retrieved, there is strong evidence that skiing or snowboarding in a TP is a risk factor for head, neck, back and severe injuries. Two papers assessed the risk factors for injuries in TPs, mainly demonstrating that features promoting aerial manoeuvres or a large drop to the ground were associated with higher feature-specific injury rates. The profile of injured skiers and snowboarders in TPs described in the literature suggested some evidence of associations between factors including activity, sex, skill level, helmet use, age and TP injuries. SUMMARY/CONCLUSIONS This systematic review demonstrates the need for studies identifying the risk factors for injuries to skiers and snowboarders and on interventions to reduce the risk of injury in TPs and HPs. Studies addressing the issue of TP design should be considered. PROSPERO REGISTRATION NUMBER CRD42016045206.

Abstract
The sport of snowboarding has grown in popularity as both a recreational winter activity as well as a prominent Olympic sport. Both forms are comprised of one of three different disciplines within the sport: freestyle, alpine, and snowboard-cross. In recent years, the increased professionalism and substantial growth of snowboarding as a global sport has increasingly attracted the interest of exercise physiologists and sport scientists. Given the small (but growing) number of studies that have been published, the research analyzing the physiological and performance characteristics and requirements of snowboarding remains limited. The absence of such studies signifies a lack of examination into this important but under-explored area of research, which could contribute valuable information to the scientific community and international snowboarding teams. The studies conducted thus far have indicated different requirements of physiological and physical traits dependent upon the specific discipline of snowboarding in question. For example, in order to meet the divers demands of each discipline, athletes must develop various qualities, such as muscular strength and power. This can increase their ability to withstand the high forces and loads on the muscular system during competition, and further decrease their risk of lower limbs injuries. At the same time, the studies acknowledge the potential advantages of aerobic fitness in terms of recovery, to more efficiently sustain the athlete through both competitive and on- and off-snow training sessions. Given the value and breadth of application of these limited studies, further analysis and research could contribute greater knowledge and benefits to the field of snowboarding. Therefore, it is the purpose of this preliminary review to explore the current literature, providing further insight into the physiological and physical demands of snowboarding performance. This preliminary review is intended to stimulate interest among the communities of exercise physiologists, sport scientists and particularly coaches in order to improve our current understanding of snowboarding and its demands as a sport. This preliminary review further seeks to develop protocols and strategies to assess physiological and performance characteristics of snowboarding, monitor athletic performance, provide practical recommendations for training, identify new areas of scientific research, and develop accurate talent identification programs.

Despite different injury rates and injury patterns previous personality related research in the field of downhill winter sports did not subdivide between different alpine slope users. In this study, we tried to find out whether the personality trait sensation seeking differs between skiers, snowboarders and ski tourers. In a cross-sectional survey 1185 persons (726 alpine skiers, 321 snowboarders and 138 ski tourers comparable in age and sex) were electronically questioned with the sensation seeking scale (SSS-V) comprising the four factors thrill and adventure seeking, experiences seeking, disinhibition and boredom susceptibility. Kruskal-Wallis Tests revealed a significantly higher total score of the SSS-V for snowboarders in comparison to alpine skiers and ski tourers (H(2) = 41.5, p < 0.001). Ski tourers and snowboarders scored significantly higher in the dimensions "thrill- and adventure-seeking" and "experience-seeking" than alpine skiers. Furthermore, snowboarders showed higher scores in "disinhibition" related to alpine skiers and ski tourers and "boredom susceptibility" compared to alpine skiers. Data show differences in the personality trait sensation seeking in people practising different winter sports. As snowboarders showed higher SS-scores compared to alpine skiers and ski tourers prevention and information programs might benefit from a selective approach focusing on special characteristics of the respective group. Key pointsIt is the very first research trying to identify differences between different types of winter sport slope usersObtained results show higher sensation seeking scores in snowboardersThese results might stimulate new approaches in educational campaigns to reduce accident rates in winter sports.

Abstract
BACKGROUND AND AIM Alpine skiing and snowboarding share the hazards of accidents accounting for tibial fractures. The aim of this study was to evaluate the fracture patterns and mechanisms of injury of tibial fractures taking place in downhill skiing and snowboarding. MATERIALS AND METHODS All patients with tibial fracture due to alpine skiing or snowboarding accident treated in four trauma centers next to the largest ski resorts in Finland were analyzed between 2006 and 2012. The hospital records were retrospectively reviewed for data collection: equipment used (skis or snowboard), age, gender, and mechanism of injury. Fractures were classified according to AO-classification. RESULTS There were 342 skiing and 30 snowboarding related tibial fractures in 363 patients. Tibial shaft fracture was the most common fracture among skiers (n = 215, 63%), followed by proximal tibial fractures (n = 92, 27%). Snowboarders were most likely to suffer from proximal tibial fracture (13, 43%) or tibial shaft fracture (11, 37%). Snowboarders were also more likely than skiers to suffer complex AO type C fractures (23% vs 9%, p < 0.05). Adult skiers had both wider variety of fractures and higher prevalence of proximal tibial fractures compared to children (49% vs 16%, p < 0.05). Skiers typically got injured due to falling down on the same level (70%) and snowboarders due to loss of control while jumping (46%). CONCLUSION The most important finding was the relatively high number of the tibial plateau fractures among adult skiers. The fracture patterns between snowboarding and skiing were different; the most common fracture type in skiers was spiral tibial shaft fracture compared to proximal tibial fractures in snowboarders. Children had more simple fractures than adults.

Abstract
Introduction Little is known about the distribution of injuries in competitive snowboarding and there are no reports describing long-term complications of professional snowboarding. To examine the injury distribution and long-term impairments in active and retired professional snowboarders, a retrospective data analysis was performed using a questionnaire. As a control group, injuries of recreational snowboarders of a southern German university clinic were examined. Methods Retired and active snowboarders were identified from the result lists of the International Ski Federation (FIS) and from the current team lists of the German-speaking European national snowboard teams. After identification, a questionnaire regarding injury distribution/treatment was sent to the athletes and the filled-in questionnaires were subsequently evaluated. Injuries in recreational snowboarding were evaluated by analyzing the medical records and surgical reports for a seven-year period. Results Compared to the available literature, significantly more severe injuries that necessitated surgical treatment in recreational snowboarders were documented. Most injuries accounted for wrist fractures but also many nonunions and spinal fractures were recorded. Between active professionals, distinct differences in injury distribution were found. The number of days off differed greatly with less days in speed disciplines (35.5 days) and the maximum number of days off in snowboardcross (51 days). Injury distribution varied clearly with more injuries of the upper extremity and ankle in speed disciplines compared to snowboardcross and freestyle professionals, who exhibited more injuries to the lower extremity and head. Freestyle athletes used significantly less protectors compared to speed (P=0.01) and snowboardcross athletes (P=0.00). An analysis of retired professionals revealed a higher number of impairments in daily life and a significantly higher number of days off snowboarding (P=0.018). Conclusion Knowledge about snowboard-specific injuries is a requirement for an appropriate treatment of these patients. This first description of long-term impairments after professional snowboarding highlights the importance of the development of specific strategies to prevent daily life impairments after a professional sports career.

Abstract
BACKGROUND Skiers and snowboarders incur a variety of injuries and medical emergencies each year at ski resorts. The ski patrol is primarily responsible for initial triage, assessment and stabilization of these problems. OBJECTIVE The purpose of this study was to subjectively evaluate the type of training, resources, and equipment available to local ski patrols within Utah. METHODS Ski patrol directors at ski resorts in Utah were asked to complete a voluntary computerized survey. RESULTS Of the 14 ski areas in Utah, ski patrol directors representing 8 resorts responded. The majority of patrols in Utah use Outdoor Emergency Care (OEC) as their primary education and certification source. Most programs also include site-specific training in addition to basic certification. All responding resorts had basic first responder equipment, including splinting devices, basic airway management, and hemorrhage control. Six of 8 responding resorts had affiliated clinics, and all had access to aeromedical transport. All of the responding ski patrol directors believed the current training level was adequate. CONCLUSIONS Utah area ski patrollers frequently see trauma-related injuries and have the resources to assess and provide initial immobilization techniques. Many resorts have affiliated clinics with advanced providers, and all have access to aeromedical support to rapidly transfer patients to trauma centers. Medical directors may be of use for training as well as developing extended scope of practice protocols for advanced airway use or medication administration. Patrols may benefit from additional resort-specific training that addresses other frequently seen injuries or illnesses.

Abstract
BACKGROUND AND AIMS The aim of this study was to provide information on incidences and severity of recreational alpine skiing and snowboarding injuries in Northern Finland and to discuss possible preventive measures to reduce the number and severity of injuries in the future. MATERIALS AND METHODS This retrospective study consists of all injured skiers and snowboarders in the Levi Ski Resort during the 2006-2012 winter seasons. The Levi Ski Resort has a SKIDATA® system which records automatically every ski-lift run taking place. The emergency system of the resort registers the data (conditions during the injury, patient characteristics, and observed and/or suspected injuries) of all injured persons they meet. The severity of injury is defined by the needed level of care: Grade 1 (treated by the emergency system with no need for further referral), Grade 2 (referral to the local primacy care clinic), Grade 3 (transfer to hospital by ambulance), and Grade 4 (transfer to tertiary care by helicopter). RESULTS During the 6-year study period, there were 29,576.132 lift runs and 2911 injuries were met by the emergency system, resulting in the average injury incidence of 0.98 injuries per 10,000 lift runs. Vice versa, the average number of the ski-lift rides needed to generate one injury was 10,160. The knee injuries of the skiers constituted almost one-third of all cases, whereas snowboarders sustained more injuries to the upper limb and axial areas. CONCLUSION Skiing and snowboarding are related to a relatively high risk of injury. The most common injuries affect the knee in skiers and the upper extremity, especially the wrist, in snowboarders. A continuous and systematic review of injuries is needed to monitor the effects of changes made in terms of the safety.

Abstract
This report presents 2 cases of subtle injuries to the subtalar joint, specifically, osteochondral defects of the middle facet of the talus and concomitant involvement of the middle talocalcaneal articulation sustained while snowboarding. The 3T magnetic resonance image revealed fracture of the lateral talar process with osteochondral lesions of the middle talocalcaneal articulation. This injury can lead to severe and chronic disability if undetected and could ultimately end athletic participation prematurely.

Abstract
Background: Skiing and snowboarding have become increasingly popular since the inception of the winter X-Games in 1997. Purpose: To determine (1) rate of return to sport (RTS) to the winter X-Games following anterior cruciate ligament (ACL) reconstruction and (2) performance upon RTS following ACL reconstruction. Hypotheses: There is a high rate of RTS to the winter X-Games in subjects undergoing ACL reconstruction. There is no difference in performance upon RTS following ACL reconstruction versus preinjury. Study Design: Case series; Level of evidence, 4. Methods: Skiers and snowboarders competing in the winter X-Games who tore their ACL and underwent ACL reconstruction between 1997 and 2012 were evaluated. Athlete data were extracted from winter X-Games media websites, ESPN, injury reports, player profiles/biographies, and press releases. All athlete, knee, and surgical demographic data were analyzed. RTS and performance as it related to the number of gold, silver, and bronze medals won both pre- and postoperatively in the X-Games were analyzed. Results: Fifteen skiers (19 knees) and 10 snowboarders (10 knees) were analyzed. There were 13 males and 12 females, with a mean subject age of 22.6 ± 4.45 years. The rate of RTS in the X-Games following ACL reconstruction was 80% overall (20/25 subjects). The rate of RTS in winter X-Games following ACL reconstruction in skiers was 87% (13/15 subjects) and in snowboarders was 70% (7/10 subjects). The rate of RTS in winter X-Games following ACL reconstruction in males and females was 85% (11/13 subjects) and 75% (9/12 subjects), respectively. The rate of revision ACL reconstruction due to ACL tear following primary ACL reconstruction was 4% (1/25 subjects). There were more left- than right-sided tears (18 vs 11). Skiers and snowboarders competed in the X-Games for 3.84 ± 2.73 and 3.40 ± 2.84 years prior to ACL reconstruction and 2.56 ± 2.06 and 7.29 ± 3.30 years after ACL reconstruction, respectively. Skiers earned 22 medals prior to ACL reconstruction (9 gold, 5 silver, 8 bronze) and 24 medals after ACL reconstruction (16 gold, 2 silver, 6 bronze). Snowboarders earned 7 medals prior to ACL reconstruction (4 gold, 1 silver, 2 bronze) and 19 medals after ACL reconstruction (7 gold, 7 silver, 5 bronze). Conclusion: Winter X-Games skiers and snowboarders have a high rate of RTS after ACL reconstruction. Skiers earned a similar number of medals preinjury and postsurgery, while snowboarders earned more medals following surgery.

Abstract
OBJECTIVE The purpose of this study was to measure support for a mandated helmet policy among resort employees along with the impact of such a policy on job satisfaction, and additionally, to measure the prevalence of barriers to helmet use among this population. METHODS In all, 728 Vail Resort employees were surveyed regarding their opinions on the helmet policy and on general helmet use. RESULTS The majority of the 728 employees surveyed (66.5%; 95% CI: 63% to 70%) agreed with the helmet policy. Only 18% (95% CI: 16% to 21%) reported a negative effect on job satisfaction. Older employees (>25 years old) were more likely to disagree with the policy (odds ratio [OR] 3.1; 95% CI: 2.2 to 4.3) and report a negative effect on job satisfaction (OR 4.8; 95% CI: 3.0 to 7.6). Skiers were much more likely than snowboarders to report a negative effect on job satisfaction (OR 9.8; 95% CI: 5.2 to 18.1). Among resort employees, ski patrollers were more likely to disagree with the mandate (OR 9.8; 95% CI: 6.8 to 13.9) and report a negative effect on job satisfaction (OR 13.2; 95% CI: 8.3 to 21.). Forty-three percent of participants (95% CI: 39% to 46%) agreed with the statement that wearing a helmet encourages reckless behavior whereas 51.0% (95% CI: 47% to 54%) believed that wearing a helmet limits sensory perception. CONCLUSIONS A mandatory helmet use policy was supported by most resort employees. However, ski patrollers and older, more experienced employees were more likely to report a negative effect on job satisfaction. Barriers to helmet use continue to persist in the ski industry and represent a target for further educational efforts.

Abstract
The physiological adaptation to training is specific to the muscle activity, dominant energy system involved, muscle groups trained, as well as intensity and volume of training. Despite increasing popularity of snowboarding only little scientific data is available on the physiological characteristics of female and male competitive snowboarders. Therefore, the purpose of this study was to compare the aerobic capacity and maximal anaerobic power of elite Polish snowboarders with untrained subjects. Ten snowboarders and ten aged matched students of Physical Education performed two exercise tests. First, a 30-second Wingate test was conducted and next, a cycle ergometer exercise test with graded intensity. In the first test, peak anaerobic power, the total work, relative peak power and relative mean power were measured. During the second test, relative maximal oxygen uptake and lactate threshold were evaluated. There were no significant differences in absolute and relative maximal oxygen uptake between snowboarders and the control group. Mean maximal oxygen uptake and lactate threshold were significantly higher in men than in women. Significant differences were found between trained men and women regarding maximal power and relative maximal power. The elite snowboarders demonstrated a high level of anaerobic power. The level of relative peak power in trained women correlated negatively with maximal oxygen uptake. In conclusion, our results seem to indicate that the demanding competition program of elite snowboarders provides a significant training stimulus mainly for anaerobic power with minor changes in anaerobic performance.

Abstract
A 33-year-old gentleman who was otherwise fit and healthy suffered repetitive low impact head injuries while snowboarding in Austria over a period of one week. During the fall he had several hyperextension injuries and presented with headache, nausea, vomiting, drowsiness (felt ‘drunk’ on Friday night despite not being drunk), diplopia, abnormal pupillary signs. A Horner’s syndrome was diagnosed and on investigation, the left intercavernous portion of internal carotid artery (ICA) was found to be thrombosed. The symptoms gradually settled after conservative treatment for a month. Blunt head trauma is a recognized cause of carotid dissection and thrombosis and many neuromechanics studies have attempted to calculate the wall shear stress involved. Physicians treating snowboarders should be aware of the condition and should look for Horner’s syndrome and consider the possibility of carotid occlusion. With a thorough PubMed, Ovid, EMBASE search using ‘snowboarding’, ‘carotid dissection’, ‘Horner’s syndrome’ no such case was found to be reported. Proper training for such sport activities is essential to avoid serious consequences.
