However, their combined contribution to running performance is unknown. We investigated the ... -
Commentary on Viewpoint: Using V̇O2max as a marker of training status in athletes - can we do better?
Hunter, Ben; Meyler, Samuel; Muniz, Daniel (2022-07-01)To the editor: Podlogar et al. (1) have presented a compelling argument for using the critical intensity as an alternative method of classifying athletes. It was concluded that the critical intensity best represents the ... -
A comparison of methods to estimate anaerobic capacity: Accumulated oxygen deficit and W' during constant and all-out work-rate profiles.
Muniz, Daniel; Pedlar, Charles; Godfrey, Richard; Glaister, Mark (2017-12-02)This study investigated (i) whether the accumulated oxygen deficit (AOD) and curvature constant of the power-duration relationship (W') are different during constant work-rate to exhaustion (CWR) and 3-min all-out (3MT) ... -
