Skiing and snowboarding are popular recreational and competitive sport activities for children and youth. Injuries associated with both activities are frequent and can be serious. There is new evidence documenting the benefit of wearing helmets while skiing and snowboarding, as well as data refuting suggestions that helmet use may increase the risk of neck injury. There is also evidence to supp...

BACKGROUND Nordic combined (NC) is an Olympic winter-sport performed as a ski jumping (SJ) event followed by a cross-country (XC) pursuit race employing the skating style. PURPOSE To elucidate the associations between sport-specific laboratory capacities and SJ, XC skiing, and overall NC performance in a world-cup NC event. METHODS Twelve international world-cup NC athletes from 8 nations p...

OBJECTIVE Snowboarding has increased in popularity worldwide, with an associated increase in injuries suffered by its participants with a significant proportion of these injuries being severe. We sought to understand the risk of sustaining a splenic injury in snowboarders as compared to skiers, and whether there are noteworthy differences in their characteristics at hospital admission. METHOD...

At the Institute for Theory and Practice of Training and Movement a model was developed to calculate the running time and the optimal trajectory in alpine skiing with the use of genetic algorithms. Up to now the results of the validation of the model were promising but the evaluation (3D-kinematic, DLT) required a lot of time. A GPS-System from the Institute for Sports and Environment offers ne...

[Purpose] The purpose of this study was to examine the effect of a 40-minute race on muscle activity and spatiotemporal cycle variables at four-time points during a 12-km roller skiing test using the double-poling technique. [Subjects and Methods] Five elite cross-country (XC) skiers on the Korean National reserve team participated in the study. Part of a biathlon course that consisted of both ...

Th is paper deals with the subject of injury in alpine skiing and snowboarding and the aim was to defi ne the characteristics of injuries and the risk factors as the basis for establishing preventive measures. Th e types of injuries and risk factors were analyzed by examining previous papers. During the last thirty years, the number of injuries has generally decreased by 50-70%. Th e changes we...

The use of regression equations to predict oxygen uptake in relation to speed, grade, power output, and anthropometric characteristics is common in cardiac rehabilitation and athlete fitness testing. Research has suggested that sport specific testing improves the reliability of the test methodology and is appropriate for the development of effective training programs. This study focused on the ...

In the sport of alpine skiing, knowledge about the centre of mass (CoM) kinematics (i.e. position, velocity and acceleration) is essential to better understand both performance and injury. This study proposes a global navigation satellite system (GNSS)-based method to measure CoM kinematics without restriction of capture volume and with reasonable set-up and processing requirements. It combines...

15 What goes through our minds While We fall asleep? at sleep onset, students preparing for exams commonly re-experience some of the material they have been revising during the day; lovers have pervasive thoughts about their romantic partner; software developers may see bits of programming codes unfold in their mind's eye. these anecdotal observations suggest that, during the transition from wa...
