Relative Body Weight and Standardised Brightness-Mode Ultrasound Measurement of Subcutaneous Fat in Athletes: An International Multicentre Reliability Study, Under the Auspices of the IOC Medical Commission
(Peer reviewed; Journal article, 2019)Introduction: Fat is a metabolic fuel, but excess body fat is ballast mass, and therefore, many elite athletes reduce body fat to dangerously low levels. Uncompressed subcutaneous adipose tissue (SAT) thickness measured ... -
Reliabilitet av isokinetiske muskelstyrkemålinger og hinketester for barn: en metodestudie
(Master thesis, 2011)Introduksjon: Hinketester og isokinetiske muskelstyrkemålinger blir mye brukt for å evaluere knefunksjon etter ACL skade. Målemetodene har demonstrert høy reliabilitet (ICC > 0,80), men studiene er i hovedsak gjennomført ... -
Reliabilitet og validitet av målemetoder for muskelstyrke hos pasienter 6 –24 måneder etter rekonstruksjon av fremre korsbånd: En reliabilitets- og validitetsstudie av isokinetisk styrketest og styrketest i beinpress-, ekstensjon- og fleksjonsapparat
(Master thesis, 2017)Introduksjon: Isokinetisk styrketest er gullstandard av objektiv muskelstyrketesting i forskning og ved retur til idrett. Dette er en reliabel og valid testmetode for å avdekke sideforskjeller i muskelstyrken. Dette er en ... -
Reliability and concurrent validity of the International Physical Activity Questionnaire short form among pregnant women
(Journal article; Peer reviewed, 2017-03)Background: The International Physical Activity Questionnaire short-form (IPAQ-SF) is frequently used to assess physical activity (PA) level in the general adult population including pregnant women. However, the reliability ... -
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 ... -
Reliability and validity of match performance analysis in soccer : a multidimensional qualitative evaluation of opponent interaction
(Doctoral thesis, 2010)Match performance analysis is widely used as a method for studying technical, tactical and physical aspects of player and team performance in a soccer match. Therefore, ensuring the validity and reliability of the collected ... -
