Effekten av to uker med høyfrekvent okklusjonstrening på variabler i det proteinnedbrytende ubiquitinproteasom systemet: hvordan påvirker okklusjonstrening mengden og lokaliseringen av variabler i ubiquitin-proteasom systemet akutt og over en treningsperiode, og er den akutte responsen lik etter 10 dager hvile mellom to treningsuker?
Amundsen, Roar (Master thesis, 2015-08-17)Innledning: Styrketrening med lav motstand og redusert blodtilførsel (okklusjonstrening) kan øke muskelstørrelse og muskelstyrke på kort tid. En tidligere studie viste stor økning i muskelfiberareal etter tre uker med ... -
