- Meta-analysis of 115 trials comparing HIIT and MVICT effects on physiological adaptations and physical performance.
- HIIT showed superior improvements in relative and absolute maximal oxygen uptake, maximal aerobic power/speed, and mean anaerobic power compared to MVICT.
- No significant differences between HIIT and MVICT in peak anaerobic power, intensity thresholds, exercise economy, and physical performance indices.
- Training status, age, sex, interval type, and exercise mode significantly moderated the effects of HIIT vs. MVICT.
- HIIT benefits were more pronounced in inactive, recreationally active, and elite/national tier individuals, males, and mixed-sex populations.
- Short-interval and long-interval HIIT, along with rowing, running, or cycling, showed greater improvements in maximal oxygen uptake.
