Reliability analysis of the 3-min all-out exercise test for cycle ergometry.

Unlabelled: The 3-min all-out exercise test (3 MT) is purported to estimate critical power (CP) and anaerobic work capacity (W') and serve as an exercise mode for measuring maximum oxygen uptake (VO(2max)). Reliability analysis of the 3 MT has been confined to CP, not W', and verification of "true" VO(2max)was exclusive to a graded exercise test (GXT).

Purpose: We conducted a reliability analysis of the 3 MT and compared VO(2max)values from the 3 MT with a GXT and an exhaustive square-wave verification bout.
