Key result
HIIT improves cardiorespiratory fitness and lowers 24-hour mean glucose in adults with type 1 diabetes.
Why the study?
Patients with T1DM face impaired cardiorespiratory fitness and glycemic control, and the effects of HIIT and its most effective protocols in this population remained to be clarified.
Does high-intensity interval training (HIIT) improve cardiorespiratory fitness and glycemic parameters in adult patients with type 1 diabetes?
Meta-Analysis (n=204)
Does high-intensity interval training (HIIT) improve cardiorespiratory fitness and glycemic parameters in adult patients with type 1 diabetes?
Standardized Mean Difference: 0.59 (95% CI 0.16–1)
p-value: p=0.01
In adults with type 1 diabetes, high-intensity interval training significantly improves cardiorespiratory fitness and reduces 24-hour mean glucose levels, supporting its use as a beneficial exercise modality.

Supports HIIT in type 1 diabetes for fitness and glucose control; extends evidence for exercise guidelines in this population.
Lazić et al. (2024) conducted a meta-analysis in Type 1 Diabetes Mellitus (n=204). High-intensity interval training (HIIT) vs. Pre-intervention (baseline) or control group was evaluated on Cardiorespiratory fitness (pre vs. post) (SMD 0.59, 95% CI 0.16 to 1, p=0.01). High-intensity interval training significantly improved cardiorespiratory fitness (SMD 0.59) and reduced 24-h mean glucose levels (SMD -0.44) in adults with type 1 diabetes.
