Reliability of Time Spent Near V̇o2max During 2 Cycling Interval Training Sessions: The Effect of V̇o2max Criteria.
Abstract: Raimundo, JAG, Tramontin, AF, Martins, EC, Borszcz, FK, Turnes, T, de Aguiar, RA, and Caputo, F. Reliability of time spent near V̇o2max during 2 cycling interval training sessions: the effect of V̇o2max criteria. J Strength Cond Res XX(X): 000-000, 2025-This study aimed to determine the reliability of the time spent near V̇o2max (tV̇o2max) during 2 work-matched cycling interval trainings and to compare tV̇o2max reliability using different V̇o2max criteria. Fifteen healthy males participated in this cross-sectional and crossover study. The participants performed on different days, an incremental ramp test followed by a V̇o2max verification test, and a test-retest model to analyze tV̇o2max during 2 distinct work-matched interval training sessions. The interval training protocols comprised 5 × 2-minute efforts with 1-minute recovery (HIIT2min:1min) or 10 × 1-minute efforts with 30-second recovery (HIIT1min:30s) at 85% of the incremental peak power output, both followed by a V̇o2max verification test. Times sustained above 90 and 95% (t95V̇o2max) of V̇o2max were analyzed and were compared based on 3 different criteria: (a) V̇o2max from incremental and verification test (V̇o2maxINC-VER); (b) V̇o2max from the verification test on the training day (V̇o2maxDAY); and (c) mean V̇o2max from V̇o2maxINC-VER and V̇o2maxDAY. There were no significant differences in test-retest tV̇o2max; the only exception was t95V̇o2max during HIIT1min:30s assessed by V̇o2maxINC-VER. The typical error of measurement and coefficient of variation ranged from 28 to 61 seconds and 19%-35% for HIIT2min:1min, and from 21 to 66 seconds and 36%-72% for HIIT1min:30s. V̇o2maxINC-VER reduced tV̇o2max coefficient of variation compared with V̇o2maxDAY for HIIT2min:1min, but not for HIIT1min:30s. Despite similar test-retest, tV̇o2max exhibited low reliability, with no improvement when a V̇o2max verification test was included on the training day.
期刊介绍：
The editorial mission of The Journal of Strength and Conditioning Research (JSCR) is to advance the knowledge about strength and conditioning through research. A unique aspect of this journal is that it includes recommendations for the practical use of research findings. While the journal name identifies strength and conditioning as separate entities, strength is considered a part of conditioning. This journal wishes to promote the publication of peer-reviewed manuscripts which add to our understanding of conditioning and sport through applied exercise science.
