Validity of oxygen uptake cut-off criteria in plateau identification during horizontal treadmill running

摘要

BACKGROUND: When determining achievement of maximal oxygen uptake ((V) over dotO(2max)) during treadmill running using speed increments, the (V) over dotO(2) cut-off criteria applied during plateau identification is often not justified, not protocol specific, or not related to actual change in (V) over dotO(2) (Delta(V) over dotO(2)) with speed increment, which can influence plateau achievement rates between studies. The purpose of this study was to compare plateau incidence using an individualised plateau criteria approach based on a "percentage" Delta(V) over dotO(2) compared to using previously established criteria of Delta(V) over dotO(2)<= 2.1 mL.kg(-1).min(-1) not developed on running speed.
