Time spent at or near V̇O₂max during high-intensity interval training - a systematic review and meta-analysis.
BMC sports science, medicine & rehabilitation·June 3, 2026·PMID 42237396
Why it mattersFor clinicians guiding exercise prescription in performance and longevity, understanding which HIIT configurations maximize tV̇O₂max helps optimize cardiorespiratory stimulus. This meta-analysis clarifies that longer and variable-intensity intervals are superior for accumulating time near V̇O₂max, informing more effective training design.
