摘要: Purpose: To assess the utility of a self-paced maximal oxygen uptake (VO2max) test (SPV) in eliciting an accurate measure VO2max comparison with traditional graded exercise (GXT) during motorized treadmill exercise. Design: This was cross-sectional experimental study whereby recreationally trained men (n = 13, 25.5 ± 4.6 y) completed 2 tests (SPV, GXT) separated by 72-h recovery period. Methods: The GXT continuous and incremental, prescribed 1-km/h increases every min until attainment VO2max. SPV consisted 5 × 2-min stages incremental exercise, which were self-selected adjusted according to RPE levels (RPE 11, 15, 17, 20). Results: Although no significant differences observed between (63.9 3.3 cf 60.9 mL · kg−1 min−1, respectively, P > .05), apparent 4.7% mean difference may be practically important. 95% limits-of-agreement analysis 3.03 11.49 min−1.
