Physiological and perceptual effects of a time trial position in submaximal cycling, and the effects of cycling position on transition running performance in well-trained triathletes
Kløvning, Møyfrid (Master thesis, 2021)Oppsummering Introduksjon: Tempostilling (TTP) benyttes hyppig av triatleter for å redusere luftmotstand under sykling. Det er mulig at TTP medfører fysiologiske og perseptuelle endringer som kan påvirke sykkel- og ... -
Physiological Response to Cycling With Variable Versus Constant Power Output
Kolsung, Erik Borg; Ettema, Gertjan; Skovereng, Knut (Peer reviewed; Journal article, 2020)Introduction: Variable power output (VP) is one of the main characteristics of a road cycling mass-start. Tolerating VP during outdoor road cycling highly influences performance. There is a lack of continuous and comprehensive ... -
Power production and biochemical markers of metabolic stress and muscle damage following a single bout of short-sprint and heavy strength exercise in well-trained cyclists

Prolonged double poling in cross-country skiing: How does it affect performance and performance-determining variables?
Veltun, Sindre Brekke (Master thesis, 2021)Prestasjons-bestemmende variable blir normalt målt fra utvilt tilstand, noe som kan avvike fra utmattet tilstand, som på slutten av en konkurranse i langløp på ski. Hensikt: Å undersøke hvordan prestasjonen reduseres under ... -
Quantification of the anaerobic contribution during low to moderate intensity exercise with different fluctuation amplitudes
