For the determination of ground reaction forces in alpine skiing, pressure insole (PI) systems and portable force plate (FP) systems are well known and widely used in previous studies. The purposes of this study were 1) to provide reference data for the vertical component of the ground reaction forces (vGRF) during alpine skiing measured by the PI and FP systems, and 2) to analyze whether the d...
OBJECTIVE To describe the epidemiology of sports injuries occurring in a community during 8 years and to evaluate the outcome of an intervention implemented against injuries occurring in downhill skiing. METHODS Hospital treated sports injuries occurring in Harstad, Norway (population 22 600) were recorded prospectively during an 8 year period. A prevention programme targeting downhill skiing...
BACKGROUND To effectively prevent injury in recreational alpine skiing, it is important to identify modifiable risk factors that can be targeted through exercise and training. Fatigue is a potential risk factor in recreational skiing, but no investigations have evaluated concentric/eccentric quadriceps and hamstring fatigue in recreational skiers. We tested the hypothesis that recreational skii...
We tested whether the rate at which force is applied to the ground sets metabolic rates during classical-style roller skiing in four ways: 1) by increasing speed (from 2.5 to 4.5 m/s) during skiing with arms only, 2) by increasing speed (from 2.5 to 4.5 m/s) during skiing with legs only, 3) by changing stride rate (from 25 to 75 strides/min) at each of three speeds (3.0, 3.5, and 4.0 m/s) durin...
There have been considerable changes in equipment design and movement patterns in the past few years both in alpine skiing and ski-jumping. These developments have been matched by methods of analysing movements in field conditions. They have yielded new insights into the skills of these specific winter sports. Analytical techniques have included electromyography, kinetic and kinematic methods a...
During a day of skiing thousands of repeated contractions take place. Previous research on prolonged recreational alpine skiing show that physiological changes occur and hence some level of fatigue is inevitable. In the present paper the effect of prolonged skiing on the recruitment and coordination of the muscle activity was investigated. Six subjects performed 24 standardized runs. Muscle act...
BACKGROUND Skiers have to differ between slow to moderate and fast skiing speed to determine their skiing style according to the ISO 11088 standard for setting binding release values. Despite existing evidence that males ski significantly faster than females, no sex-specific factor was inserted into the ISO 11088 standard. OBJECTIVE To evaluate factors potentially associated with the percepti...
The purpose of the study was to examine potential differences between male and female alpine ski naive young people in attitudes towards alpine skiing before and after the completion of structured alpine ski school program. We included 136 ski beginners (41 women and 95 men) who anonymously filled out a previously validated 26-item Lickert scale-type questionnaire related to their attitudes tow...
BACKGROUND Systematic surveillance of injuries and illnesses is the foundation for developing preventive measures in sport. AIM To analyse the injuries and illnesses that occurred during the XXII Olympic Winter Games, held in Sochi in 2014. METHODS We recorded the daily occurrence (or non-occurrence) of injuries and illnesses (1) through the reporting of all National Olympic Committee (NOC)...
Cross-country skiing has always been one of the most popular winter sports in Scandinavia (Eriksson, 1976). Although downhill skiing has become more and more popular during the last ten years, cross-country skiing is still the most important mass sport in Finland. The number of competitive skiers has been increasing owing to the fact that the younger age groups as well as the veteran series hav...
