Effect of Sitting Posture on Sit-Skiing Economy in Non-disabled Athletes
2020
This study focused on resolving the differences in economy between two common sit-skiing postures used by disabled athletes, suspected to be the most and least effective. Ten experienced non-disabled male cross-country skiers went through an incremental testing protocol with an ergometer simulating double poling in two sitting postures “kneeing” and “knee-high.” The protocol consisted of 3 × 4 min steady-state stages (13, 22, and 34% of maximal sprint power output). Subjects' respiratory gases and heart rate were measured and blood lactate concentrations were determined. In addition, pulling forces and motion capture recordings were collected. Oxygen consumption was 15.5% (p < 0.01) higher …

Yhdistetyn kestävyys- ja nopeusvoimaharjoittelun vaikutukset kestävyyssuorituskykyyn sekä voima- ja nopeusominaisuuksiin kestävyysurheilijoilla
2001
Eija Salonen. Yhdistetyn kestävyys- ja nopeusvoimaharjoittelun vaikutukset kestävyyssuorituskykyyn sekä voima- ja nopeusominaisuuksiin kestävyysurheilijoilla. Voima- ja kestävyysharjoittelun yhdistämistä on pidetty ongelmallisena, sillä vaikutusmekanismeiltaan nama harjoitusmenetelmät poikkeavat selvästi toisistaan. Kestävyysurheilijoilla nopeusvoimatyyppisen harjoittelun on todettu kehittävän nopeusvoimaa, kuitenkaan heikentämättä kestävyysominaisuuksia. Hiihdossa ja ampumahiihdossa tarvitaan erittäin hyvää aerobista kapasiteettia sekä kilpailuvauhtien kasvaessa hyvää hermo-lihasjärjestelmän toimintakykyisyyttä. Nopeusvoiman harjoittaminen saattaa jopa parantaa kestävyyssuoritusta, koska l…

Aiming strategy affects performance-related factors in biathlon standing shooting
2021
This study focused on investigating differences in shooting performance and performance related factors between two different aiming strategies (HOLD, low radial velocity during the approach 0.4‐0.2 seconds before triggering, and TIMING, high radial velocity) in biathlon standing shooting. 23 biathletes fired 8x5 standing shots at rest (REST) and 2x5 shots during a race simulation (RACE). Shooting performance (hit point distance from the center of the target), aiming point trajectory and postural balance were measured from each shot. Shooting performance was similar both at REST (HOLD 33±5 mm vs TIMING 38±8 mm, p=0.111) and in RACE (40±11 mm vs 47±12 mm, p=0.194). Better shooting performanc…
Ski economy and physiological responses while double poling : curved vs. straight poles
2015
Christina Mishica (2015). Ski economy and physiological responses while double poling: curved vs. straight poles. Department of Biology of Physical Activity, University of Jyväskylä, Master’s Thesis in Exercise Physiology. 57 pp. Introduction. Double poling (DP) is commonly used in cross country skiing (XC). It is becoming more and more popular and in some competitions it is the exclusive technique. Ski poles allow a skier to apply power and force to the snow and their composition and design have a significant effect on performance. Different pole lengths and cross sections are some of the differences that have been tested. Advancements in equipment will continue to be introduced so it is i…
Energetic demands and nutritional strategies of elite cross-country skiers during Tour de Ski : A narrative review
2021
The Tour de Ski (TDS: 6–9 sprint and distance races across 9–11 days) represents the most intense competition series of the cross-country (XC) ski season and is characterized by accumulated stress from consecutive days of high-intensity (~ 85%–160% VO2max) racing, travel, cold temperatures and low to moderate altitude (500–1500 m above sea level). Here, nutritional strategies play a key supportive role for optimized health, recovery and performance. This narrative review aims to provide an evidence-based discussion on the energetic demands of the TDS and recommendations for nutritional strategies to optimize health and performance of XC skiers during and following the TDS. We highlight seve…
