The Efficacy Of A Verification Stage For Determining Vo2max And The Impact Of Sampling Time, Emily J. Kontos

Senior Honors Projects, 2020-current

Purpose: Verification phases may improve the validity of maximal oxygen uptake (VO_2max) measurements during maximal graded exercise testing (GXT). It is not known whether VO₂ sampling times influence the necessity of a verification stage. Methods: 15 female and 18 male test subjects (18 – 25 y) completed a treadmill incremental GXT. Speed was increased from 3.0 mph by 0.5 mph every minute until 6.0 mph was reached. Elevation was then increased by 3% every minute until volitional fatigue. Subjects then walked for five minutes at 3.0 mph and 0% grade; after which time the verification stage began …
