The fibrotic interstitial lung diseases (fILD) is a group of debilitating chronic lung conditions that are characterised by scarring of lung tissue, dyspnoea on exertion and significant physical impairment. Exercise training is recommended for people with fILD in improving breathlessness and exercise tolerance. However, despite the best efforts of patients and clinicians, many of those who participate are not attaining its benefits. The current exercise training strategies of moderate intensity continuous training may not be well suited to fILD. High intensity interval training (HIIT), short bouts of high-intensity exercise regularly interspersed with periods of rest or light exercise may be an alternate exercise training option for people with fILD. The study will determine to whether HIIT is better than the current method of continuous exercise training at moderate intensity in improving exercise tolerance, breathlessness and quality of life in people with fILD. A randomised controlled, assessor blinded trial will be conducted. A total 130 people with fILD will be randomly assigned to moderate intensity continuous training or HIIT. If this trial demonstrates that HIIT is effective, it will provide an exercise training strategy that can readily be implemented in practice that will maximise the outcomes of exercise training for people with fILD.
