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 compares HIIT to moderate-intensity continuous training (MICT) for outcomes like fasting blood glucose, 2-hour plasma glucose, and cardiorespiratory fitness. It was authored by Jun Li, registered in PROSPERO, and last updated on May 14, 2026.

Use Cases

• Comparing HIIT and MICT effectiveness for glycemic control based on fasting blood glucose and 2-hour plasma glucose outcomes.
• Evaluating the impact of HIIT on cardiorespiratory fitness in prediabetic populations based on standardized mean difference metrics.
• Assessing the certainty of evidence for exercise interventions using GRADE methodology described in the review.
• Identifying gaps in research for future trials based on the limited number of studies and short-term interventions noted.

Strengths

• The review is registered in PROSPERO (CRD42024605154), indicating a formal protocol.
• It includes a risk of bias assessment using the Cochrane Risk of Bias 2 tool.
• It provides specific effect size estimates (e.g., MD -0.16 mmol/L for 2hPG) with confidence intervals and certainty ratings (low to moderate).

Limitations

• The file size is 19.1 KB, indicating a limited scope document rather than a large dataset.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description notes a limited number of eligible studies (13), preventing quantitative synthesis for some comparisons.
