A new training assessment method for alpine ski racing: Estimating center of mass trajectory by fusing inertial sensors with periodically available position anchor points
(Journal article; Peer reviewed, 2018)In this study we present and validate a method to correct velocity and position drift for inertial sensor-based measurements in the context of alpine ski racing. Magnets were placed at each gate and their position determined ... -
Biomechanical analysis of defensive cutting actions during game situations: six cases in collegiate soccer competitions
(Journal article; Peer reviewed, 2015-07-10)The strengths of interpersonal dyads formed by the attacker and defender in one-on-one situations are crucial for performance in team ball sports such as soccer. The purpose of this study was to analyze the kinematics of ... -
The influence of pole lengths on O2-cost, kinematics, and performance in double poling at high speeds before and after a training period with long poles
(Peer reviewed; Journal article, 2019)Purpose: Previous studies have found an acute performance improvement with longer pole lengths in double poling (DP) at low-to-moderate speeds. We investigated the influence of pole lengths (PL) on O2-cost, 3D kinematics, ... -
Pole lengths influence O2-cost during double poling in highly trained cross-country skiers
(Journal article; Peer reviewed, 2017)Purpose: In elite cross-country skiing, double poling is used in different terrain. This study compared O2-cost and kinematics during double poling with four different pole lengths [self-selected (SS), SS − 5 cm, SS + 5 ... -
The influence of pole length on performance, O2-cost and kinematics in double poling
(Journal article; Peer reviewed, 2016-04-27)Purpose: In the double poling cross-country skiing technique, the propulsive forces are transferred solely through the poles. The aim of the present study was to investigate how pole length influences double poling ... -
Three-dimensional body and centre of mass kinematics in alpine ski racing using differential GNSS and inertial sensors
(Journal article; Peer reviewed, 2016-08-22)A key point in human movement analysis is measuring the trajectory of a person’s center of mass (CoM). For outdoor applications, differential Global Navigation Satellite Systems (GNSS) can be used for tracking persons since ...
