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.
