Meta-Analysis of HIIT Effects on Glycemic Control in Adults with Prediabetes

A systematic review and meta-analysis of 13 intervention studies evaluating high-intensity interval training (HIIT) in adults with prediabetes. The document, authored by Jun Li, compares HIIT to moderate-intensity continuous training (MICT) for outcomes like fasting blood glucose and cardiorespiratory fitness. The review was registered in PROSPERO and includes studies searched from database inception to January 2026.

Use Cases

• Comparing the efficacy of HIIT versus MICT for glycemic control based on the meta-analysis results.
• Assessing the certainty of evidence for exercise interventions in prediabetes based on the GRADE framework mentioned.
• Identifying research gaps for future trials based on the review's conclusions about short-term studies and low evidence certainty.

Strengths

• Includes a specific number of studies (13 intervention studies) in the analysis.
• Reports quantitative effect sizes with confidence intervals (e.g., MD -0.16 mmol/L for 2hPG).
• Uses established methodological frameworks (Cochrane Risk of Bias 2, GRADE) as stated in the description.

Limitations

• The primary data file is a 19.8 KB DOCX document, indicating a very limited scope as a summary report rather than a raw dataset.
• Row count and column-level documentation are unknown, limiting suitability for direct computational analysis.
• The description notes the evidence certainty for key outcomes was 'low to very low' and many studies were short-term.
