Biomechanical and neuromuscular performance requirements of horizontal deceleration: A review with implications for random intermittent multi-directional sports
Harper, Damian J.; McBurnie, Alistair J.; Santos, Thomas Dos’; Eriksrud, Ola; Evans, Martin; Cohen, Daniel D.; Rhodes, David; Carling, Christopher; Kiely, John (Peer reviewed; Journal article, 2022)Rapid horizontal accelerations and decelerations are crucial events enabling the changes of velocity and direction integral to sports involving random intermittent multi-directional movements. However, relative to horizontal ... -
Hand reach star excursion balance test
Eriksrud, Ola (Doctoral thesis, 2019)Background: Different tests for dynamic postural control; i.e., the ability to maintain a stable base while completing a movement, are frequently used to assess functional and athletic performance. Current tests primarily ... -
Hand reach star excursion balance test: An alternative test for dynamic postural control and functional mobility
Eriksrud, Ola; Federolf, Peter Andreas; Anderson, Patrick Julian; Cabri, Jan (Journal article; Peer reviewed, 2018)Tests of dynamic postural control eliciting full-body three-dimensional joint movements in a systematic manner are scarce. The well-established star excursion balance test (SEBT) elicits primarily three-dimensional lower ... -

The relationship between selected load-velocity profile parameters and 50 m front crawl swimming performance
Gonjo, Tomohiro; Njøs, Nikolai; Eriksrud, Ola; Olstad, Bjørn Harald (Peer reviewed; Journal article, 2021)The purpose of the present study was to establish relationships between sprint front crawl performance and a swimming load-velocity profile. Fourteen male national-level swimmers performed 50 m front crawl and semi-tethered ... -
Relationship between stability and variability ofthe core in dynamic reaching tasks
Eriksrud, Ola; Cabri, Jan; Federolf, Peter Andreas (Peer reviewed; Journal article, 2019)Core stability is important to many functional and athletic tasks. Motion variability has been proposed as a measure to characterize core stability. Based on motor learning theories, the current study hypothesized that ... -
Reliability of load-velocity profiling in front crawl swimming
Olstad, Bjørn Harald; Gonjo, Tomohiro; Njøs, Nikolai; Abächerli, Kathrin; Eriksrud, Ola (Peer reviewed; Journal article, 2020)The purposes of this study were to establish test-retest reliability of calculating load-velocity profiles in front crawl swimming using five and three different external loads, and if outcome results were comparable between ... -
Reliability of phase-specific outcome measurements in change-of-direction tests using a motorized resistance device
Westheim, Frederic; Gløersen, Øyvind; Harper, Damian; Laugsand, Håkon Nilsen; Eriksrud, Ola (Peer reviewed; Journal article, 2023)This study aims to determine test-retest reliability of phase-specific information during initial acceleration, deceleration, and re-acceleration phases of different change-of-direction (CoD) tests using a motorized ... -
