The current study simulated cross-country skiing on varying terrain by using a power balance model. By applying the hypothetical inductive deductive method, we compared the simulated position along the track with actual skiing on snow, and calculated the theoretical effect of friction and air drag on skiing performance. As input values in the model, air drag and friction were estimated from the...

Leading the aggression in some athletes ensures productivity; however, misleading does not give the same result. The aggression may reach dangerous extents. Nevertheless, aggressive behavior can be regarded as a relaxation. One of the important reasons of violence and aggression seen in sports is the belief that it increases the performance or success. Based upon these arguments, we aim to exam...

BACKGROUND Alpine skiing and snowboarding are popular winter activities worldwide, enjoyed by participants of all ages and skill levels. There is some evidence that the incidence of traumatic brain injury (TBI) and spinal cord injury (SCI) in these activities may be increasing. These injuries can cause death or severe debilitation, both physically and emotionally, and also result in enormous fi...

The purpose of the study was to compare tubing-related injuries to wakeboarding- and water skiing-related injuries. Data was collected from the 2000-2007 National Electronic Injury Surveillance Survey for 1,761 individuals seeking care at an emergency department due to a tubing-, wakeboarding, or water skiing-related injury. Data included patient age and sex, as well as injury characteristics i...

We explore here the evolution of skiing locomotion in the last few thousand years by investigating how humans adapted to move effectively in lands where a cover of snow, for several months every year, prevented them from travelling as on dry ground. Following historical research, we identified the sets of skis corresponding to the 'milestones' of skiing evolution in terms of ingenuity and techn...

In this paper we identify skier groups in data from RFID ski lift gates entrances. The ski lift gates’ entrances are real-life data covering a 5-year period from the largest Serbian skiing resort with a 32,000 skier per hour ski lift capacity. We utilize three representative algorithms from three most widely used clustering algorithm families (representative-based, hierarchical, and density bas...

The lower extremity dexterity test quantifies sensorimotor control for cross country skiing. Introduction: Research on top-level crosscountry skiing ability is predominately centered on the athlete´s physical fitness, biomechanical aspects of the skiing technique, and materials that make up ski hardware. Results concerning aerobic endurance capacity have been extended by new findings regarding ...

BACKGROUND Skiing is a very popular sport in Austria. Nevertheless, there is little information concerning online monitoring of bio-signals during alpine skiing in the mountains. Within the last years innovative scientific monitoring tools for evaluating features of neurocardial fitness have been developed. AIMS The goal of this study was to demonstrate the new 'Fire of Life' heart rate varia...
