Evaluating High Intensity Interval Training Versus Moderate Intensity Continuous Training in Fibrotic Interstitial Lung Disease: Insights from a Randomized Controlled Trial

Highlight

• High intensity interval training (HIIT) was compared with standard moderate intensity continuous training (MICT) in patients with fibrotic interstitial lung disease (fILD) during pulmonary rehabilitation.
• Both HIIT and MICT resulted in clinically important improvements in cycle endurance time and six-minute walk distance without significant differences between the two exercise modalities.
• HIIT was safe, well-tolerated, and had similar adherence and intensity achievements compared to MICT, suggesting it is a viable alternative exercise strategy in fILD.
