Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Change in endurance time

    Endurance time measured during constant work rate test (CWRT) at 75% of the peak work rate achieved on a baseline cardiopulmonary exercise test (CPET).

    Baseline, nine weeks and 6 months following intervention

Secondary Outcomes (10)

  • Change in dyspnea measured using the Dyspnea-12 questionnaire

    Baseline, nine weeks and 6 months following intervention

  • Changes in fatigue evaluated by the Fatigue Severity Scale

    Baseline, nine weeks and 6 months following intervention

  • Change in health related quality of life using the St George's Respiratory Questionnaire idiopathic pulmonary fibrosis specific version (SGRQ-I)

    Baseline, nine weeks and 6 months following intervention

  • Change in health related quality of life using the chronic respiratory disease questionnaire (CRQ)

    Baseline, nine weeks and 6 months following intervention

  • Change in anxiety and depression measured by the Hospital Anxiety and Depression Scale

    Baseline, nine weeks and 6 months following intervention

  • +5 more secondary outcomes

Study Arms (2)

High Intensity Interval Training

EXPERIMENTAL

Participants will undergo a twice-weekly supervised exercise training program for eight weeks. Each session will involve 36 minutes of interval aerobic exercise on a cycle ergometer alternating every 30 seconds between 100% of peak work rate, achieved on the cardiopulmonary exercise test (CPET), plus upper and lower resistance training.

Other: High intensity interval training

Traditional pulmonary rehabilitation

ACTIVE COMPARATOR

Participants will undergo a twice-weekly supervised exercise training program for eight weeks. Each session will involve 30 minutes of continuous aerobic exercise on a cycle ergometer at 60% of the peak work rate achieved on the CPET, plus upper and lower resistance training.

Other: Traditional pulmonary rehabilitation

Interventions

36 minutes of interval exercise on cycle ergometer alternating every 30 seconds between 100% peak work rate achieved on cardiopulmonary exercise test and unloaded cycling

High Intensity Interval Training

30 minutes of continuous exercise on cycle ergometer at 60% peak work rate achieved on cardiopulmonary exercise test.

Traditional pulmonary rehabilitation
