Whole-body vibrations associated with alpine skiing
Matej Supej, Jan Ogrin, Hans-Christer Holmberg
Izvirni znanstveni članek
Oznake: biomechanics;injury prevention;kinematics;kinetics;recreational skiing;shock;ski racing;
Alpine skiing, both recreational and competitive, is associated with high rates of injury. Numerous studies have shown that occupational exposure to whole-body vibrations is strongly related to lower back pain and some suggest that, in particular, vibrations of lower frequencies could lead to overus ...

Asymmetries in the technique and ground reaction forces of elite alpine skiers influence their slalom perfermance
Matej Supej, Jan Ogrin, Nejc Šarabon, Hans-Christer Holmberg
Izvirni znanstveni članek
Oznake: biomehanika;kinematika;globalni navigacijski satelitski sistem;vzajemna inercija gibanja;tekmovalno smučanje;pritiskovni vložki;
Background: Although many of the movements of skiers are asymmetric, little is presently known about how such asymmetry influences performance. Here, our aim was to examine whether asymmetries in technique and the ground reaction forces associated with left and right turns influence the asymmetries ...

Application of experimental measurements in a wind tunnel to the development of a model for aerodynamic drag on elite slalom and giant slalom alpine skiers
Matej Majerič, Nina Verdel, Jan Ogrin, Hans-Christer Holmberg, Matej Supej
Izvirni znanstveni članek
Oznake: sport;biomechanics;mechanical modelling;energy;dissipation;energy loss;coefficient of aerodynamic drag;cross-sectional area;performance;GNSS;GPS;
Aerodynamic drag is a major cause of energy losses during alpine ski racing. Here we developed two models for monitoring the aerodynamic drag on elite alpine skiers in the technical disciplines. While 10 skiers assumed standard positions (high, middle, tuck) with exposure to different wind speeds (4 ...

Reliability and validity of the core sensor to assess CORE body temperature during cycling exercise
Nina Verdel, Tim Podlogar, Urška Ciuha, Hans-Christer Holmberg, Tadej Debevec, Matej Supej
Izvirni znanstveni članek
Oznake: merjenje temperature;športniki;kolesarstvo;veljavnost;zanesljivost;telesna temperatura jedra;rektalna temperatura;senzor CORE;kolesarjenje;neinvazivno;validity;reliability;core body temperature;rectal temperature;CORE sensor;cycling;non-invasive;
Monitoring core body temperature (T$_c$) during training and competitions, especially in a hot environment, can help enhance an athlete’s performance, as well as lower the risk for heat stroke. Accordingly, a noninvasive sensor that allows reliable monitoring of T$_c$ would be highly beneficial in t ...

Asymmetries in ground reaction forces during turns by elite slalom alpine skiers are not related to asymmetries in muscular strength
Jan Ogrin, Nejc Šarabon, Mads Kjær Madsen, Uwe G. Kersting, Hans-Christer Holmberg, Matej Supej
Izvirni znanstveni članek
Oznake: smučanje;alpsko smučanje;slalom;vrhunski športniki;asimetrije;jakost;zmogljivost;sport;skiing;alpine skiing;elite skiers;asymmetries;muscular strength;reaction forces;turns;
The ground reaction forces (GRF) associated with competitive alpine skiing, which are relatively large, might be asymmetric during left and right turns due to asymmetries in the strength of the legs and torso and the present investigation was designed to evaluate this possibility. While skiing a sym ...
