High-intensity interval training (HIIT) has gained attention as a potentially effective alternative to traditional exercise modalities for individuals with type 2 diabetes mellitus (T2DM). Previous studies have evaluated this exercise strategy with various regimens, comparator groups and outcomes, limiting the generalisability of findings. We performed a novel umbrella review to generate an up-to-date synthesis of the available evidence regarding the effect of HIIT on glycaemic control and other clinically relevant cardiometabolic health outcomes in individuals with T2DM, as compared with traditional moderate-intensity continuous training (MICT) and/or non-exercise control (CON).

- - The study aimed to determine if high-intensity interval training (HIIT) is more effective than moderate-intensity continuous training (MICT) or no exercise for improving components of metabolic syndrome (MetS) in affected individuals.
- - A systematic review analyzed 23 randomized controlled trials (RCTs) with 1374 participants, finding that HIIT significantly improved various health metrics like waist circumference, blood pressure, cholesterol levels, triglycerides, and blood glucose compared to non-exercise control.
- - The results suggest that HIIT is a beneficial exercise option for enhancing cardiometabolic health, with low-volume HIIT being as effective as higher-volume workouts, making it a practical alternative to traditional aerobic exercise.
Background: Although the efficacy of interval training for improving body composition has been summarized in an increasing number of systematic reviews in recent years, discrepancies in review findings and conclusions have been observed.
Objective: This study aims to synthesize the available evidence on the efficacy of interval training compared with moderate-intensity continuous training (MICT) and nonexercise control (CON) in reducing body adiposity in apparently healthy adults.
Methods: An umbrella review with meta-analysis was performed.
Article Synopsis
- - The study conducted an umbrella review to assess the effects of high-intensity interval training (HIIT) on cardiorespiratory fitness (CRF) in adults, comparing it with both non-exercise control groups and traditional moderate-intensity continuous training (MICT).
- - A total of 24 systematic reviews, including nearly 13,000 participants, showed that HIIT, especially sprint interval training (SIT), significantly improves CRF compared to non-exercise groups and MICT, with results being consistent across various populations and HIIT types.
- - While the reviews highlighted the effectiveness of HIIT, most were rated as having moderate to critically low methodological quality, suggesting that the findings should be interpreted with caution. *
