Meta-analysis of high-intensity interval training and alternative modalities for enhancing aerobic and anaerobic endurance in young athletes.

ABSTRACT: This meta-analysis examined whether HIIT outperforms low-intensity endurance training (LIET), generic training (GT), or sport-specific drills (SSD) in improving aerobic and anaerobic endurance in youth athletes. Systematic searches of PubMed, MEDLINE, SPORTDiscus, and Web of Science identified studies comparing HIIT with LIET, GT, or SSD in athletes aged ≤18 years. Outcomes included maximal oxygen uptake (VO₂max), continuous endurance, intermittent endurance, and repeated sprint ability. Random-effects meta-analyses computed standardized mean differences, with risk of bias and sensitivity analyses conducted. Twenty-eight studies (N = 707, 10.7% female) met inclusion criteria. HIIT elicited significantly greater VO₂max improvements than GT (g = 0.97; p < 0.01) and also
