[Ab] Resumo:The aim of this study was to advance current movement analysis methodology to enable a technique analysis in sports facilitating (1) concurrent comparison of the techniques between several athletes; (2) identification of potentially beneficial technique modifications and (3) a visual representation of the findings for feedback to the athletes. Six elite cross-country skiers, three world cup winners and three national elite, roller ski skated using the V2 technique on a treadmill while their movement patterns were recorded using 41 reflective markers. A principal component analysis performed on the marker positions resulted in multi-segmental "principal" movement components (PMs). A novel normalisation facilitated comparability of the PMs between athletes. Additionally, centre of mass (COM) trajectories were modelled. We found correlations between the athletes' performance levels (judged from race points) and specific features in the PMs and in the COM trajectories. Plausible links between COM trajectories and PMs were observed, suggesting that better performing skiers exhibited a different, possibly more efficient use of their body mass for propulsion. The analysis presented in the current study revealed specific technique features that appeared to relate to the skiers' performance levels. How changing these features would affect an individual athlete's technique was visualised with animated stick figures.

[Ab] Resumo:In this study micro-sensors were employed to analyse macro-kinematic parameters during a classical cross-country skiing competition (10 km, 2-lap). Data were collected from eight male participants during the Australian championship competition wearing a single micro-sensor unit (MinimaxX™, S4) positioned on their upper back. Algorithms and visual classification were used to identify skiing sub-techniques and calculate velocities, cycle lengths (CL) and cycle rates (CR) over the entire course. Double poling (DP) was the predominant cyclical sub-technique utilised (43 ± 5% of total distance), followed by diagonal stride (DS, 16 ± 4%) and kick double poling (KDP, 5 ± 4%), with the non-propulsive Tuck technique accounting for 24 ± 4% of the course. Large within-athlete variances in CL and CR occurred, particularly for DS (CV% = 25 ± 2% and CV% = 15 ± 2%, respectively). For all sub-techniques the mean CR on both laps and for the slower and faster skiers were similar, while there was a trend for the mean velocities in all sub-techniques by the faster athletes to be higher. Overall velocity and mean DP-CL were significantly higher on Lap 1, with no significant change in KDP-CL or DS-CL between laps. Distinct individual velocity thresholds for transitions between sub-techniques were observed. Clearly, valuable insights into cross-country skiing performance can be gained through continuous macro-kinematic monitoring during competition.

[Ti] Título:Maturity status influences the relative age effect in national top level youth alpine ski racing and soccer.

[Ab] Resumo:Since the relative age effect (RAE) characterizes a problem in all age categories of alpine ski racing and soccer and the fact that, yet, to date the underlying factors have not been well investigated, the aim of the present study was to assess the influence of the biological maturity status on the RAE among youth alpine ski racers (YSR) and soccer players (SP). In total, 183 male and female YSR selected for national final races and 423 male SP selected for Elite Youth Development Centres were investigated. Additionally, a comparison group of 413 non-athletes was evaluated. The birth months were split into four relative age quarters. The biological maturity status was assessed by the age at peak height velocity (APHV) method; according to the M±SD of the comparison group, the athletes were divided into normal, early and late maturing. Chi2-tests indicated a significant RAE among YSR (χ2(3,N = 183) = 18.0; p<0.001; ω = 0.31) and SP (χ2(3,N = 423) = 33.1; p<0.001; ω = 0.28). In total, only a small number of late maturing athletes were present (0.5-2.3%). Among relatively younger athletes, high percentages of early maturing athletes were found (43.1-43.3%). The findings indicate that relatively younger and less mature athletes are marginalized or totally excluded in alpine ski racing and soccer. Thus, selection criteria in both sports are effectively based on early biological development and relatively older age, both of which should be considered in future in the talent selection process. In this context, the easy feasible method of assessing the APHV can be used.

[Ab] Resumo:We aimed to elucidate potential differential effects of hypoxia on cardiorespiratory responses during submaximal cycling and simulated skiing exercise between adults and pre-pubertal children. Healthy, low-altitude residents (adults, N=13, Age=40±4yrs.; children, N=13, age=8±2yrs.) were tested in normoxia (Nor: P O =134±0.4 mmHg; 940 m) and normobaric hypoxia (Hyp: P O =105±0.6 mmHg; ~3 000 m) following an overnight hypoxic acclimation (≥12-hrs). On both days, the participants underwent a graded cycling test and a simulated skiing protocol. Minute ventilation (V ), oxygen uptake (VO ), heart rate (HR) and capillary-oxygen saturation (SpO ) were measured throughout both tests. The cycling data were interpolated for 2 relative workload levels (1 W·kg & 2 W·kg ). Higher resting HR in hypoxia, compared to normoxia was only noted in children (Nor:78±17; Hyp:89±17 beats·min ; p<0.05), while SpO was significantly lower in hypoxia (Nor:97±1%; Hyp:91±2%; p<0.01) with no between-group differences. The V , VO and HR responses were higher during hypoxic compared to normoxic cycling test in both groups (p<0.05). Except for greater HR during hypoxic compared to normoxic skiing in children (Nor:155±19; Hyp:167±13 (beats·min ); p<0.05), no other significant between-group differences were noted during the cycling and skiing protocols. In summary, these data suggest similar cardiorespiratory responses to submaximal hypoxic cycling and simulated skiing in adults and children.

[Ti] Título:Impact of Prehospital Transportation on Survival in Skiers and Snowboarders with Traumatic Brain Injury.

[Ab] Resumo:INTRODUCTION: Prehospital helicopter use and its impact on outcomes in snowboarders and skiers incurring traumatic brain injury (TBI) is unknown. The present study investigates the association of helicopter transport with survival of snowboarders and skiers with TBI, in comparison with ground emergency medical services (EMS), by using data derived from the National Trauma Data Bank (2007-2014). METHODS: Primary and secondary endpoints were defined as in-hospital survival and absolute risk reduction based upon number needed to transport (treat) respectively. Multivariable regression models including traditional logit model, model fitted with generalized estimating equations, and those incorporating results from propensity score matching methods were used to investigate the association of helicopter transport with survival compared with ground EMS. RESULTS: Of the 1018 snowboarders and skiers who met the criteria, 360 (35.4%) were transported via helicopters whereas 658 (64.6%) via ground EMS with a mortality rate of 1.7% and 1.5%, respectively. Multivariable log-binomial models demonstrated association of prehospital helicopter transport with increased survival (odds ratio 8.58; 95% confidence interval 1.09-67.64; P = 0.041; absolute risk reduction: 10.06%). This finding persisted after propensity score matching (odds ratio 24.73; 95% confidence interval 5.74-152.55; P < 0.001). The corresponding absolute risk reduction implies that approximately 10 patients need to be transported via helicopter to save 1 life. CONCLUSIONS: Based on our robust statistical analysis of retrospective data, our findings suggest prehospital helicopter transport improved survival in patients incurring TBI after snowboard- or ski-related falls compared with those transported via ground EMS. Policies directed at using helicopter services at remote winter resorts or ski or snowboarding locations should be implemented.

[Ti] Título:Influence of slope steepness, foot position and turn phase on plantar pressure distribution during giant slalom alpine ski racing.

[Ab] Resumo:The purpose of this study was to investigate the evolution of ground reaction force during alpine skiing turns. Specifically, this study investigated how turn phases and slope steepness affected the whole foot normal GRF pattern while performing giant slalom turns in a race-like setting. Moreover, the outside foot was divided into different plantar regions to see whether those parameters affected the plantar pressure distribution. Eleven skiers performed one giant slalom course at race intensity. Runs were recorded synchronously using a video camera in the frontal plane and pressure insoles under both feet's plantar surface. Turns were divided according to kinematic criteria into four consecutive phases: initiation, steering1, steering2 and completion; both steering phases being separated by the gate passage. Component of the averaged Ground Reaction Force normal to the ski's surface([Formula: see text], /BW), and Pressure Time Integral relative to the entire foot surface (relPTI, %) parameters were calculated for each turn phases based on plantar pressure data. Results indicated that [Formula: see text] under the total foot surface differed significantly depending on the slope (higher in steep sections vs. flat sections), and the turn phase (higher during steering2 vs. three other phases), although such modifications were observable only on the outside foot. Moreover, [Formula: see text] under the outside foot was significantly greater than under the inside foot.RelPTI under different foot regions of the outside foot revealed a global shift from forefoot loading during initiation phase, toward heel loading during steering2 phase, but this was dependent on the slope studied. These results suggest a differentiated role played by each foot in alpine skiing turns: the outside foot has an active role in the turning process, while the inside foot may only play a role in stability.

[Ab] Resumo:INTRODUCTION AND AIM: There are no high mountains or any advantageous circumstances for winter sports in Hungary, yet within the 10 million population there are about half a million people (the exact number is 550,000) who tend to go for skiing or snowboarding abroad. Authors compared the injury statistical data with results described in the international literature in order to develop conclusions about the differences in the injury patterns and frequency between the Hungarian ones' and those found in countries with plenty of winter sport possibilities. METHOD: Authors analysed the winter sport injury cases of an insurance company. All the injury happened abroad and the assistance provider of the insurance company has managed the patient treatment and repatriation. Three winter seasons (12 months) data was analysed from the point of view of injuries frequency at different body parts and areas. Due to the fact that only limited information was available a simple statistical method was applied. RESULTS: Of 222 cases 90.5% were ski-related injury and 8.6% were snowboard injury. As for the skiers, the upper limb injuries accounted for 21.9%, the truncal region for 24.4% and the lower limb for 55.8%. Among snowboarders the upper limb injuries accounted for 36.9%, the truncal region for 37% and the lower limb for 26.1%. The most frequent was the knee (36.8%), the wrist (12.4) and the shoulder (11.4) injury. Skier's thumb injury was only 1.5%. The most common snowboard injury was the wrist trauma (31.6%), the head/neck/face was accounted 15.8% of all the injuries. And the ankle was injured in 10.5% of all the cases. The head/neck and the knee injury often combined with injuries of some other body part. 29 patients (13%) had to be repatriated, the most frequent reason for the repatriation was the injury of the lower limb. CONCLUSIONS: The Hungarian sportsmen's injury patterns do not always follow data described in the international literature, but they correspond to data of countries with similar geographical situation. The injury rate of knee and of the shoulder displays same data, the injury rate of the wrist was more frequent than in the international data, and this is true both for skiers and the snowboarders. The Hungarians' injury of the truncal region (mainly the head) was more frequent, but on the other hand the general injury rate of other body parts proved to be a lower number. It seems that the frequent use of the protective equipment and the preventive measures applied by the Hungarians are mirrored in the lower injury figures. Orv. Hetil., 2017, 158(16), 618-624.

[Ab] Resumo:CONTEXT: Up to 75% of skateboarders and snowboarders admitted to the hospital sustain head injuries. It is unclear why not all children and teenagers wear helmets while snowboarding and skateboarding given the protection they afford. OBJECTIVES: To report on the prevalence of, and factors associated with, skateboarding and snowboarding in injured children and to explore factors that influence helmet use, head injury, and hospitalization in this sample. DESIGN: A cross-sectional study of skateboard- and snowboard-associated injuries from 2003 to 2012 among individuals younger than age 18 years using National Electronic Injury Surveillance System (NEISS) data from approximately 100 hospitals. MAIN OUTCOME MEASURES: Helmet use, head injury, and hospitalization. RESULTS: Of 1742 patients in the study, 852 (48.9%) and 890 (51.1%) were skateboarders and snowboarders, respectively. Overall, 907 (52.1%) did not use helmets, and 704 (40.4%) sustained head injuries. Multiple logistic regression analysis showed that age, race/ethnicity, location of boarding, and engaging in skateboarding influenced helmet use. Sex, race/ethnicity, helmet use, and skateboarding predicted head injury. Age, sex, skateboarding, and head injury predicted hospital admission. CONCLUSION: Statistically significant differences exist in helmet use, head injury, and hospitalization rates between skateboarders and snowboarders. Our findings suggest that injury prevention and outreach programs are needed to increase helmet use and reduce the risk of head injury and hospitalization in skateboarders and other at-risk groups. Further studies are needed to clarify the association between race/ethnicity and helmet use among skateboarders and snowboarders.

[Ab] Resumo:BACKGROUND: Cardiac trauma is associated with a much higher mortality rate than injuries to other organ systems, even though cardiac trauma is identified in less than 10% of all trauma admissions. Here we report blunt trauma of the left atrium due to snowboarding trauma. CASE PRESENTATION: A 45-year-old Asian man collided with a tree while he was snowboarding and drinking. He lost consciousness temporarily. An air ambulance was requested and he was transported to an advanced critical care center. On arrival, a pericardial effusion was detected by a focused assessment with sonography for trauma. His presenting electrocardiogram revealed normal sinus rhythm and complete right bundle branch block. Laboratory findings included a white blood cell count of 13.5 × 10 /µl, serum creatine kinase level of 459 IU/l, and creatine kinase-myocardial band level of 185 IU/l. Enhanced computed tomography showed a large pericardial effusion and bleeding from his left adrenal gland. There were no pelvic fractures. A diagnosis of cardiac tamponade due to blunt cardiac injury and left adrenal injury due to blunt trauma was made. Subsequently, emergency thoracic surgery and transcatheter arterial embolization of his left adrenal artery were performed simultaneously. A laceration of the left atrial appendage in the lateral wall of his left ventricle was detected intraoperatively and repaired. His postoperative course progressed favorably, although a pericardial effusion was still detected on chest computed tomography on hospital day 35. His electrocardiogram showed normal sinus rhythm and the complete right bundle branch block pattern changed to a narrow QRS wave pattern. He was discharged on hospital day 40. CONCLUSIONS: The present case report illustrates two points: (1) severe injuries resulted from snowboarding, and (2) complete right bundle branch block was caused by blunt cardiac injury. The present report showed blunt trauma of the left atrium with complete right bundle branch block as an electrocardiogram change due to snowboarding trauma. To detect cardiac trauma in snowboarding accidents, an examination of an electrocardiogram is required in all patients who might have a bruised chest.
