A Comparison of Frontal Theta Activity During Shooting among Biathletes and Cross-Country Skiers before and after Vigorous Exercise
Luchsinger, Harri; Sandbakk, Øyvind; Schubert, Michael; Ettema, Gerardus Johannes C; Baumeister, Jochen (Journal article; Peer reviewed, 2016)Background Previous studies using electroencephalography (EEG) to monitor brain activity have linked higher frontal theta activity to more focused attention and superior performance in goal-directed precision tasks. In ... -
Contribution from cross-country skiing, start time and shooting components to the overall and isolated biathlon pursuit race performance
Luchsinger, Harri Simon; Kocbach, Jan; Ettema, Gerardus Johannes C; Sandbakk, Øyvind (Peer reviewed; Journal article, 2020)Purpose Biathlon is an Olympic sport combining 3–5 laps of cross-country skiing with rifle shooting, alternating between the prone and standing shooting positions between laps. The individual distance and the sprint are ... -
The influence of exercise modality on training load management
Sandbakk, Øyvind; Haugen, Thomas André; Ettema, Gerardus Johannes C (Journal article; Peer reviewed, 2021)Purpose: To provide novel insight regarding the influence of exercise modality on training load management by (1) providing a theoretical framework for the impact of physiological and biomechanical mechanisms associated ... -
On the existence of step-to-step breakpoint transitions in accelerated sprinting
Ettema, Gerardus Johannes C; McGhie, David; Danielsen, Jørgen; Sandbakk, Øyvind; Haugen, Thomas (Journal article; Peer reviewed, 2016)Accelerated running is characterised by a continuous change of kinematics from one step to the next. It has been argued that breakpoints in the step-to-step transitions may occur, and that these breakpoints are an essential ... -
The role of incline, speed and work rate on the choice of technique in classical roller skiing
Løkkeborg, Johannes Alnes; Ettema, Gerardus Johannes C (Peer reviewed; Journal article, 2020)Cross-country skiers use different sub-techniques like ‘gears’ (diagonals stride, double poling with kick, and double poling) depending on terrain (incline) and demand (speed and external work rate). Previous studies have ...
