This study evaluated two approaches for estimating the total propulsive force on a skier’s center of mass (COM) with double-poling (DP) and V2-skating (V2) skiing techniques. We also assessed the accuracy and the stability of each approach by changing the speed and the incline of the treadmill. A total of 10 cross-country skiers participated in this study. Force measurement bindings, pole force sensors, and an eight-camera Vicon system were used for data collection. The coefficient of multiple correlation (CMC) was calculated to evaluate the similarity between the force curves. Mean absolute force differences between the estimated values and the reference value were computed to evaluate the accuracy of each approach. In both DP and V2 techniques, the force–time curves of the forward component of the translational force were similar to the reference value (CMC: 0.832–0.936). The similarity between the force and time curves of the forward component of the ground reaction force (GRF) and the reference value was, however, greater (CMC: 0.879–0.955). Both approaches can estimate the trend of the force–time curve of the propulsive force properly. An approach by calculating the forward component of GRF is a more appropriate method due to a better accuracy.

Evaluating objective measures of impairment to trunk strength and control for cross-country sit skiing
Rosso, Valeria; Linnamo, Vesa; Vanlandewijck, Yves; Rapp, Walter; Fasel, Benedikt; Karczewska-Lindinger, Magdalena; Lindinger, Stefan; Gastaldi, Laura (Springer, 2021)In Paralympic cross-country sit skiing, athlete classification is performed by an expert panel, so it may be affected by subjectivity. An evidence-based classification is required, in which objective measures of impairment ... -
Changes in biomechanics of skiing at maximal velocity caused by simulated 20 km skiing race using V2 skating technique
Ohtonen, Olli; Lindinger, Stefan J.; Göpfert, Caroline; Rapp, Walter; Linnamo, Vesa (Wiley-Blackwell Publishing Ltd., 2018)This study investigated how the fatigue caused by a 20-km simulated skating cross-country skiing race on snow affects the final spurt performance from a biomechanical perspective. Subjects performed a 100-m maximal skiing ... -

Contribution and effectiveness of ski and pole forces in selected roller skiing techniques on treadmill at moderate inclines
Zhao, Shuang; Lindinger, Stefan; Ohtonen, Olli; Linnamo, Vesa (Frontiers Media SA, 2023)Background: Most of the studies about the effects of incline on cross-country skiing are related to the metabolic efficiency. The effective skiing biomechanics has also been indicated to be among the key factors that may ... -
Assessment of Heart Rate Variability Thresholds from Incremental Treadmill Tests in Five Cross-Country Skiing Techniques
Mendia-Iztueta, Ibai; Monahan, Kristen; Kyröläinen, Heikki; Hynynen, Esa (Public Library of Science, 2016)The assessment of heart rate variability (HRV) thresholds (HRVTs) as an alternative of Ventilatory thresholds (VTs) is a relatively new approach with increasing popularity which has not been conducted in cross-country ...
