HIIT Effects on Adolescent Athletes: A Systematic Review and Meta-Analysis

A 644.7 KB document summarizing a systematic review and meta-analysis of 35 studies involving 988 trained adolescent athletes. The work, authored by Fengming Zhang and published on figshare, evaluates the effects of high-intensity interval training on various physical fitness outcomes. The document was last updated on May 18, 2026.

Use Cases

• Evaluating the efficacy of HIIT on VO2max based on pooled effect sizes
• Comparing training effects on sprint performance across different distances based on subgroup analyses
• Assessing the impact of HIIT on change-of-direction ability using the reported standardized mean differences

Strengths

• The analysis is based on 35 studies and 988 athlete participants, providing a substantial evidence base
• It employs rigorous methodological standards, including Cochrane RoB 2 and GRADE for assessing risk of bias and evidence certainty
• The document reports specific effect sizes (SMD) and confidence intervals for multiple fitness outcomes like VO2max, sprint, and jump performance

Limitations

• The dataset is a single 644.7 KB document; its scope is limited to the review's text and findings
• Column-level documentation for any underlying data is absent; field semantics must be inferred from the text
• The row count for any potential underlying data tables is unknown, which may limit suitability assessment
