Determination of peak oxygen uptake, the anaerobic threshold and efficiency in Paralympic sitting sports - With emphasis on the influence of test mode and protocol
Baumgart, Julia Kathrin (Doctoral theses at NTNU, 2018:342, Doctoral thesis, 2018)SUMMARY Endurance exercise performance is mainly determined by peak oxygen uptake (VO2peak), percentage of VO2peak used at the anaerobic threshold and efficiency. Furthermore, a high VO2peak increases tolerance for higher ... -
