ObjectivesTo describe the incidence, type, aetiology and severity of injuries sustained by the International Ski Federation World Cup level female ski jumpers during the 2017–18 season.DesignProspective cohort study.MethodsSixty-seven female ski jump athletes from 16 countries were followed throughout the 17-week winter season. Preseason baseline demographic data and injury history were recorded via questionnaire. Prospective biweekly reports and retrospective end-of-season interviews provided data on all injuries requiring medical attention.ResultsSeventeen injuries were recorded, corresponding to an incidence of 25.4 injuries/100 athletes/season. The incidence of time-loss and severe injuries were found to be 17.9 and 4.5, respectively. The knee was the most common site of injury (4/17; 23.5%). Fourteen injuries occurred on the ski jump hill and crash-landing was the most common mechanism of injury (10/14; 71%). Eighty-five per cent of all moderate and severe injuries occurred in snow or windy conditions. Length of jumps resulting in injury averaged 83.7% (95% CI 72.9% to 94.4%) of hill size. Moderate injuries causing 8–28 days absence from training activities were most common (7/17; 41%) and there were three severe injuries necessitating >4 weeks absence.ConclusionInjuries among elite female ski jumpers are common and the majority are acute, resulting in time loss from training and competition. The knee was the most common site of injury and poor weather conditions may be a risk factor. Future studies are needed to identify risk factors for injury and to guide injury prevention initiatives.

Baseline Information

ObjectivesTo define incidence and injury patterns of International Ski Federation (FIS) World Cup (WC) women ski jumpers over three seasons.MethodsSki jump athletes competing in the Women’s FIS WC were recruited for prospective injury surveillance from 2017–2018 to 2019–2020. Team representatives recruited the athletes annually and prospectively recorded all injuries requiring medical attention. Retrospective end-of-season interviews corroborated injury surveillance. Medical doctors collected and processed the data. The 4-month competitive season was used to calculate the annual incidence of injuries per 100 athletes per season. Injury type, location, severity and aetiology were reported.ResultsAthletes from 19 nations were enrolled equalling 205 athlete-seasons. Mean age was 21.2 years (SD=3.8). Thirty-nine injury events resulted in 54 total injuries (26.3 injuries/100 athletes/season). Injuries were mostly acute (83%) and occurred on the ski jump hill (78%). The most common injury location was the knee (n=18, 33%). Crash landings were the most common cause of injury events (70%). Nearly half of the acute ski jump injury events occurred in snowy, windy or cloudy conditions (44%) and/or during telemark landings (46%), and most jumps (96%) were shorter than hill size. One third of the injuries were severe, and 78% of severe injuries involved the knee.ConclusionAcute injury events occur relatively frequently in elite women ski jumpers, most resulting in time-loss from sport and a significant proportion involving serious knee injuries. Crash landing was the leading cause of injury. This baseline information can be used to guide and evaluate future efforts at injury prevention.

Purpose this study aims to show the patterns and outcome of pediatric injury among those living in Albaha region in Saudi Arabia Methods this is a cross-sectional descriptive household-based study, included children between 0-17 years old both male and female. The data were collected with structured questionnaire between 20 Nov – 20 Dec 2018 and  analyzed with SPSS version 25 Results the total of participants was 257 injured child. 199(77.4%) are male and 58(22.6%) are female. About 44%of them were injured at pre-school level and 56% were traumatized at school age. The least incidence of injury occurred in those less than 2 yrs and higher incidence in those between 3-10 yrs old. The most common mechanism of injury was falling from height. The most affected group age by RTA accidents was 11-17 yrs old. Approximately 83% of the injured children required hospital management. Only one third of the injuries were  associated complications. The most common injured anatomic part was the upper limb and the least affected part was the spine. Only 5% of the injuries were associated with a disability and the common was loss of organ or part of it. Paralysis occurred in less than 1% and head injury resulted in disabilities more than 1%. Conclusion the vast majority of the injuries in our participants are not serious. The severe injuries were associated with RTA-related trauma. Most of injuries due to falling from height are not serious. We recommend not to allow the children to drive cars. Keywords: pediatric injuries; injury patterns; household.

ObjectiveTo compare injury rates among professional men’s football teams that have a winter break in their league season schedule with corresponding rates in teams that do not.Methods56 football teams from 15 European countries were prospectively followed for seven seasons (2010/2011–2016/2017)—a total of 155 team-seasons. Individual training, match exposure and time-loss injuries were registered. Four different injury rates were analysed over four periods within the season, and linear regression was performed on team-level data to analyse the effect of winter break on each of the injury rates. Crude analyses and analyses adjusted for climatic region were performed.Results9660 injuries were reported during 1 447 011 exposure hours. English teams had no winter break scheduled in the season calendar: the other European teams had a mean winter break scheduled for 10.0 days. Teams without a winter break lost on average 303 days more per season due to injuries than teams with a winter break during the whole season (p<0.001). The results were similar across the three periods August–December (p=0.013), January–March (p<0.001) and April–May (p=0.050). Teams without a winter break also had a higher incidence of severe injuries than teams with a winter break during the whole season (2.1 severe injuries more per season for teams without a winter break, p=0.002), as well as during the period January–March (p=0.003). A winter break was not associated with higher team training attendance or team match availability. Climatic region was also associated with injury rates.ConclusionsThe absence of a scheduled winter break was associated with a higher injury burden, both before and during the two periods following the time that many European teams take a winter break. Teams without a winter break (English clubs) had a higher incidence of severe injuries following the time of the year that other teams (other European clubs) had their scheduled break.

Safety Outcomes

The increasing number of registered road crashes involving cyclists during the last decade and the high proportion of road crashes resulting in severe injuries and fatalities among cyclists constitutes a global issue for community health, urban development and sustainability. Nowadays, the incidence of many risk factors for road crashes of cyclists remains largely unexplained. Given the importance of this issue, the present study has been conducted with the aim of determining relationships between infrastructural, human factors and safety outcomes of cyclists. Objectives: This study aimed, first, to examine the relationship between key infrastructural and human factors present in cycling, bicycle-user characteristics and their self-reported experience with road crashes. And second, to determine whether a set of key infrastructural and human factors may predict their self-reported road crashes. Methods: For this cross-sectional study, a total of 1064 cyclists (38.8% women, 61.2% men; M = 32.8 years of age) from 20 different countries across Europe, South America and North America, participated in an online survey composed of four sections: demographic data and cycling-related factors, human factors, perceptions on infrastructural factors and road crashes suffered. Results: The results of this study showed significant associations between human factors, infrastructural conditions and self-reported road crashes. Also, a logistic regression model found that self-reported road crashes of cyclists could be predicted through variables such as age, riding intensity, risky behaviours and problematic user/infrastructure interactions. Conclusions: The results of this study suggest that self-reported road crashes of cyclists are influenced by features related to the user and their interaction with infrastructural characteristics of the road.

Abstract Background Young, planted forests are particularly vulnerable to wildfire. High severity effects in planted forests translate to the loss of previous reforestation investments and the loss of future ecosystem service gains. We conducted prescribed burns in three ~35-year-old mixed conifer plantations that had previously been masticated and thinned during February in order to demonstrate the effectiveness of winter burning, which is not common in the Sierra Nevada, California. Results On average, 59% of fine fuels were consumed and the fires reduced shrub cover by 94%. The average percent of crown volume that was damaged was 25%, with no mortality observed in overstory trees 1 year following the fires. A plot level analysis of the factors of fire effects did not find strong predictors of fuel consumption. Shrub cover was reduced dramatically, regardless of the specific structure that existed in plots. We found a positive relationship between crown damage and the two variables of Pinus ponderosa relative basal area and shrub cover. But these were not particularly strong predictors. An analysis of the weather conditions that have occurred at this site over the past 20 years indicated that there have consistently been opportunities to conduct winter burns. On average, 12 days per winter were feasible for burning using our criteria. Windows of time are short, typically 1 or 2 days, and may occur at any time during the winter season. Conclusions This study demonstrates that winter burning can be an important piece of broader strategies to reduce wildfire severity in the Sierra Nevada. Preparing forest structures so that they can be more feasible to burn and also preparing burn programs so that they can be nimble enough to burn opportunistically during short windows are key strategies. Both small landowners and large agencies may be able to explore winter burning opportunities to reduce wildfire severity.

Context: Musculoskeletal injuries (MSKIs) are ubiquitous during initial entry military training, with overuse injuries in the lower extremities the most frequent. A common mechanism for overuse injuries is running, an activity that is an integral part of United States Coast Guard (USCG) training and a requirement for graduation. Objective: Assess the effects of athletic footwear choice on lower quarter MSKI risk in USCG recruits. Design: Descriptive Epidemiological Study Setting: USCG Training Center, Cape May, NJ Participants: A retrospective cohort study was performed in which 1229 recruits (1038 males, 191 females) were allowed to self-select athletic footwear during training. A group of 2876 recruits (2260 males, 616 females) who trained under a policy that required obligatory wear of prescribed athletic shoes served as a control. Main Outcome Measures: Demographic data and physical performance were derived from administrative records. Injury data were abstracted from a medical tracking database. Multivariable logistic regression was used to assess group, age, sex, height, body mass, and run times on MSKI outcomes. Results: Ankle-foot, leg, knee and lumbopelvic-hip complex diagnoses were ubiquitous in both groups (experimental: 20.37 to 29.34 per 1000 recruits; control: 18.08 to 25.59 per 1000 recruits). Group was not a significant factor for any of the injuries assessed. Sex was a significant factor in all injury types, with female recruits demonstrating ~2.00 greater odds of experiencing running-related injuries (RRIs), overuse injuries, or any MSKI in general. When considering ankle-foot or bone stress injuries, the risk in female recruits was 3.73 to 4.11 greater odds than their male counterparts. Run time was a significant predictor in RRI, all overuse injuries, and for any MSKI in general. Conclusion: While footwear choice did not influence MSKI risk in USCG recruits, female sex was a primary, nonmodifiable intrinsic risk factor.

Abstract. Climate change is already affecting the entire world, with extreme weather conditions such as drought, heat waves, heavy rain, floods and landslides becoming more frequent, including Europe. In according to Paris agreement and relative European announcement of Carbon neutrality (by 2050), the saving of water and energy supplies is a fundamental aspect in the management of resources in production, sports, hospitality facilities and so on. Some methodologies for the optimization of the consumption of natural resources are required. This article describes an activity aimed at measuring, monitoring and analysing the thickness of the snowpack on the ski slopes during the winter season to permit a sustainable approach of snowmaking in alpine ski areas . The authors propose a methodology based on the integration of multitemporal surface (ground/snow) survey by Autonomous Aerial Vehicle (AAV) and low cost GNSS receivers mounted on snow groomers for a RTK (Real Time Kinematic) solution. To obtain a complete snow surface digital models with poor detailed images on ski slopes, some pre-processing techniques have been analysed to locally improve contrast and details with a local high pass filtering. The methodology has been employed in two study areas (Limone Piemonte, Prato Nevoso) located in the province of Cuneo, in the southern alpine area of Piedmont.

Travel Distances

The awarding of the hosting of the Football World Cup to Russia and Qatar initiated discussions about temperature and travel distances related to the game. This study examines the effect of weather conditions, travel distances, and rest days—three factors potentially causing fatigue—on running performance using player-level and teamlevel data from the 2014 World Cup. The results show that the heat index (combining temperature and humidity) significantly decreased running performance (number of sprints, high-intensity running), while a clear sky was positively associated with distance covered at high intensity. Travel distance and rest were insignificant. When these models are used to predict running performance at the 2022 Qatar World Cup, the projections show that the combination of heat and wind could hinder the performance of both players and teams and create potentially dangerous conditions. The present study has implications for policy makers regarding the choice of future host countries.

AbstractInjuries effect the performance of athletes. Severity of injuries is determined by time loss and sporting performance reduction. To treat injuries adequately, it is necessary to get an overview of varied injuries types in different sports disciplines. In a retrospective study 7.809 athletes from Germany, Switzerland and Austria competing in competitive or recreational levels of sports were included. Injury prevalence was highest in team sports (75%), followed by combat (64%), racquet (54%) and track and field (51%). Knee (28%) and shoulder (14%) were the most at risk joints. Time loss in sporting activity after injury was longest in the region of knee (26 weeks). Of all reported injuries, 48% were accompanied by a reduced level of performance. The highest injury prevalence occurred in the year 2016 (45%). More injuries occurred during training (58%) compared to competition (42%). Across Olympic disciplines, a large number of injuries occurred during training sessions. Injury frequency increased as the Olympic games drew closer. Knee and shoulder injuries were the most severe injuries with respect to time loss and reduction sporting performance.
