A multi-sensor system for automatic analysis of classical cross-country skiing techniques
Seeberg, Trine Margrethe; Tjønnås, Johannes; Rindal, Ole Marius Hoel; Haugnes, Pål; Dalgard, Steffen Harald; Sandbakk, Øyvind (Journal article; Peer reviewed, 2017)Commercial systems utilizing data from inertial measurement units (IMUs) to analyse movement patterns have not yet been adapted to monitor daily training in cross-country (XC) skiing. The main purposes of this study are ... -
Assessment of Basic Motions and Technique Identification in Classical Cross-Country Skiing
Tjønnås, Johannes; Trine, Seeberg; Rindal, Ole Marius Hoel; Haugnes, Pål; Sandbakk, Øyvind (Journal article; Peer reviewed, 2019)Cross-country skiing is a popular Olympic winter sport, which is also used extensively as a recreational activity. While cross-country skiing primarily is regarded as a demanding endurance activity it is also technically ... -
Automatic Classification of Sub-Techniques in Classical Cross-Country Skiing Using a Machine Learning Algorithm on Micro-Sensor Data
Rindal, Ole Marius Hoel; Seeberg, Trine Margrethe; Tjønnås, Johannes; Haugnes, Pål; Sandbakk, Øyvind (Journal article; Peer reviewed, 2018)The automatic classification of sub-techniques in classical cross-country skiing provides unique possibilities for analyzing the biomechanical aspects of outdoor skiing. This is currently possible due to the miniaturization ... -
Blood Pressure Response and Pulse Arrival Time During Exercise Testing in Well-Trained Individuals
Heimark, Sondre; Eitzen, Ingrid; Vianello, Isabella; Bøtker-Rasmussen, Kasper; Mamen, Asgeir; Rindal, Ole Marius Hoel; Waldum-Grevbo, Bård; Sandbakk, Øyvind; Seeberg, Trine Margrethe (Peer reviewed; Journal article, 2022)Introduction: There is a lack of data describing the blood pressure response (BPR) in well-trained individuals. In addition, continuous bio-signal measurements are increasingly investigated to overcome the limitations of ... -
Estimation of mechanical power output employing deep learning on inertial measurement data in roller ski skating
Uddin, Md Zia; Seeberg, Trine Margrethe; Kocbach, Jan; Liverud, Anders E.; Gonzalez, Victor; Sandbakk, Øyvind; Meyer, Frederic (Peer reviewed; Journal article, 2021)The ability to optimize power generation in sports is imperative, both for understanding and balancing training load correctly, and for optimizing competition performance. In this paper, we aim to estimate mechanical power ... -
