A kinematic and kinetic study of alpine skiing technique in slalom
(Doctoral thesis, 2010)Despite a large body of lay and professional literature covering numerous aspects of alpine skiing technique, only a limited number of published scientific investigations have examined the relationship between skier ... -
A biomechanical analysis of how rider behavior and equivalent fall height affect landing stability in World Cup Big air in freeski and snowboard.
(Master thesis, 2023)Purpose: This study aimed to examine the impact of equivalent fall height (EFH) and rider behavior on landing stability among snowboard and freeski World Cup athletes participating in a Big air event. Furthermore, the study ... -
A biomechanical study on the effect of bouncing in front squats
(Master thesis, 2020)The purpose of this study was to compare performance, and biomechanics between a dynamic front squat, and a paused front squat variation. Specifically, we investigated how removing the bounce affected the execution of the ... -
Changes in posture and balance performance during five days of wobble board training
(Master thesis, 2013)Introduction: Human postural control is facilitated through postural movements such as ankle-, hip-, or multi-joint strategies. Principal component analysis (PCA) applied to kinematic marker offers a novel approach study ... -
Characterisation of skiers’ mechanics, course setting and terrain geomorphology in World Cup Alpine Skiing using global navigation satellite systems: Injury risk, performance and methodological aspects
(Doctoral thesis, 2014)This study was undertaken to characterize course setting, terrain geomorphology and skier mechanics in World Cup (WC) alpine skiing. Since there was no existing appropriate methodology to capture skier mechanics across ... -
En sammenligning av tredimensjonale og todimensjonale målemetoder og subjektiv vurdering av knekontroll i frontalplan ved landing fra vertikalt fallhopp
(Master thesis, 2014)Bakgrunn: Fremre korsbåndsskade er en alvorlig skade med lang behandlingstid for spilleren og store kostnader for samfunnet. Stadig flere kvinner deltar i idrett og med den økte deltakelsen har også antall idrettsskader ... -
External forces acting in direction of travel and their relation to energy dissipation in slalom
(Master thesis, 2008)The share of literature describing the kinetics of alpine skiing is limited in general, but especially for the discipline slalom. In recent kinematical studies energy dissipation, a measure for the quality of skiing, turned ... -
Fordeling av leddmomenter mellom albue- og skulderledd ved seks ulike varianter av push-ups med ulike hånd- og albueposisjoner.
(Master thesis, 2022)Hensikt: Det er mangel på studier vedrørende kinetikk-basert kvantifikasjon av push-ups øvelser (Dhahbi, et al., 2022). Siden bruk av øvelsen er utbredt og blir benyttet i mange ulike sammenhenger, er vi avhengig av en ... -
Hand reach star excursion balance test
(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 ... -
Kinetic and kinematic analysis of the lower extremities during a vertical drop-jump with and without an overhead target: Implications for ACL injury screening
(Master thesis, 2013)Former studies have indicated that knee valgus angles and -moments in a Vertical Drop-Jump (VDJ) can predict future Anterior Cruciate Ligament (ACL) injuries. The use of an overhead target has proved to improve effort ... -
The kinetic characteristics in competitive slalom skiing
(Master thesis, 2009)The purpose of the present study was to quantify and describe ground reaction forces in competitive slalom skiing. Background: Recent alpine skiing research has measured forces in skiing using instrumentation which ... -
Muscle mechanics in diagonal stride cross-country skiing and the effect of speed and incline
(Master thesis, 2021)Background: In gaits, such as running and walking, decoupling of the muscle fascicles length changes from the length changes of whole muscle-tendon unit (MTU), allows muscle fascicles to work almost isometrically and close ... -
Performance in golf putting
(Doctoral thesis, 2010)Putting, which accounts for about 40 - 45 % of shots in elite golf, is a complex skill. To perform in putting an elite player needs to master green reading, putter aim and technique. Mental skills, equipment and strategy ... -
Posterior pelvic tilt in Barbell back squats: a biomechanical analysis
(Master thesis, 2015-10-21)The squat is one of the most used exercises in both performance and rehabilitation exercise programs (37). Squatting with a full ROM is beneficial for increasing strength and cross sectional area of the working muscles ... -
Reliability and methodological concerns of vertical drop jumping and sidestep cutting tasks: implications for ACL injury risk screening
(Doctoral thesis, 2015)Vertical drop jumping (VDJ) and sidestep cutting tasks have been suggested as movement screening tasks to identify players with increased risk for ACL injury. Previous studies have investigated the reliability of kinematics ... -
Sammenhenger mellom anatomiske risikofaktorer og maksimale valgusmomenter, valgusvinkler og valgusbevegelse ved fallhopp: en biomekanisk tverrsnit[t]sstudie blant kvinnelige elite håndball- og fotballspillere
(Master thesis, 2011)Bakgrunn for studien: Fremre korsbåndsskader er et alvorlig problem i ball- og pivoteringsidretter som håndball og fotball. Generell leddlaksitet, genu recurvatum, knelaksitet og skjevstillinger av underekstremitetene ... -
Star excursion balance tests as a measure of functional joint mobility: an exploratory study
(Master thesis, 2016-08-15)Background: The Star Excursion Balance Test (SEBT) consists of 8 directional foot reaches on each leg, and it is used to evaluate dynamic balance and postural control in single leg stance. The SEBT has been able to ... -
The effect of 8 weeks of stretching training on knee-joint range of motion and hamstring muscle archietcture
(Master thesis, 2012)Aim: The present study, therefore, was designed to investigate the effect of 8 weeks of flexibility training on knee joint range of motion and hamstring muscle architecture during active and passive joint movement. Hypotheses: ... -
Validation of loaded Change of Direction tests using Robotic Resistance Technology
(Master thesis, 2021)Change of direction (CoD) is a fundamental part of field and team sports. It consist of an initial acceleration and deceleration into the a turn with a subsequent re-acceleration in another direction. A myriad of tests has ...
