Key Takeaway
Consider aerobic plus resistance plus breathing training to improve 6-minute walk distance in patients with interstitial lung disease.

This systematic review and network meta-analysis evaluated the impact of various exercise modalities on functional capacity and quality of life in 1,409 adults with interstitial lung disease. The study compared aerobic training (AER), aerobic plus resistance training (AER_RES), respiratory-focused training (BREATH_IMT), aerobic plus resistance plus breathing training (AER_RES_BREATH), and mind-body exercise (MIND_BODY) against a control group.

Findings indicate that all active modalities improved 6-minute walk distance (6MWD) compared to controls. AER_RES_BREATH produced the greatest estimated improvements, with a mean difference of 57.12 m compared to control. When compared directly to other modalities, AER_RES_BREATH showed a mean difference of 27.67 m over AER and 25.18 m over AER_RES. Regarding quality of life, AER_RES, AER_RES_BREATH, and MIND_BODY all improved SGRQ total scores by 10.08 to 15.20 points.

The authors note that comparisons for 6MWD between AER_RES_BREATH and other active modalities relied mainly on indirect evidence. Furthermore, results for FVC% predicted showed only a small improvement with AER_RES_BREATH (MD 3.08 percentage points) and were noted to have limited robustness and low confidence. These results should not be interpreted as evidence of disease modification. Due to limited direct comparisons, no single intervention is designated as optimal.

How this fits prior evidence

This finding addresses a gap in non-pharmacological management for interstitial lung disease by evaluating exercise modalities. While previous evidence notes that sarcopenia is associated with increased mortality risk in patients with interstitial lung disease, this study provides evidence that active exercise training improves functional exercise capacity and may improve health-related quality of life.

Living with interstitial lung disease can make even simple movements feel like a mountain to climb. For many patients, the goal is to improve their daily mobility and overall quality of life. A large review of data from over 1,400 adults found that all types of active exercise helped patients walk further during a six-minute test compared to no exercise at all.

Among the different routines, a specific combination of aerobic training, resistance training, and breathing exercises showed the greatest improvements in walking distance. While other methods like mind-body exercise and standard aerobic training also helped, the combined approach provided the most significant gains in physical capacity. These results suggest that a multi-pronged approach to exercise might be particularly effective for those with lung conditions.

It is important to note that while the walking results were strong, other measures like lung capacity showed only small improvements with the combined training. Because many of the comparisons were indirect, researchers cannot yet name one single method as the absolute best. However, the evidence clearly shows that staying active is a powerful way to improve daily function and quality of life.

What this means for you:
Combining aerobic, resistance, and breathing exercises provides the greatest boost to walking distance for lung patients.

Common questions

What kind of exercise is best for lung disease?

All active exercise types, including aerobic training and mind-body exercises, helped patients walk further. However, a combination of aerobic, resistance, and breathing training showed the greatest improvements in walking distance compared to other methods.

Does exercise improve lung capacity?

Only the combination of aerobic, resistance, and breathing training showed a small improvement in predicted lung capacity. Because these results were not very robust, they should not be seen as a way to change the underlying disease.

How much did walking distance improve?

Patients doing the combined aerobic, resistance, and breathing training walked significantly further than those doing only aerobic training or just resistance training. The results for walking distance were the most reliable findings in the study.

IntroductionExercise training is central to pulmonary rehabilitation for interstitial lung disease (ILD), but the comparative effects of different exercise modalities remain uncertain. We compared their effects on exercise capacity, pulmonary function, and health-related quality of life.MethodsSix databases were searched from inception to June 11, 2026. Randomized controlled trials of exercise training in adults with ILD were included. Interventions were classified as aerobic training (AER), aerobic plus resistance training (AER_RES), respiratory-focused training comprising breathing exercises or inspiratory muscle training (BREATH_IMT), aerobic plus resistance plus breathing training (AER_RES_BREATH), mind–body exercise (MIND_BODY), or control (CON). Frequentist random-effects network meta-analyses evaluated changes in 6-min walk distance (6MWD), percentage predicted forced vital capacity (FVC% predicted), and St George's Respiratory Questionnaire (SGRQ) total score. Mean differences (MDs) with 95% confidence intervals (CIs) were estimated. RoB 2 and CINeMA were used to assess risk of bias and confidence in the evidence.ResultsTwenty-six trials involving 1,409 participants were included. Compared with CON, all active modalities improved 6MWD, with MDs ranging from 29.46 m for AER (95% CI 11.82–47.10) to 57.12 m for AER_RES_BREATH (95% CI 41.76–72.48). AER_RES_BREATH produced greater estimated improvements than AER (MD 27.67 m, 95% CI 4.25–51.08) and AER_RES (MD 25.18 m, 95% CI 6.69–43.68), although these comparisons relied mainly on indirect evidence. Only AER_RES_BREATH showed a small improvement in FVC% predicted versus CON (MD 3.08 percentage points, 95% CI 0.05–6.12), with limited robustness and low confidence. AER_RES, AER_RES_BREATH, and MIND_BODY improved SGRQ total scores (MDs 10.08–15.20 points). Findings for 6MWD were the most robust across sensitivity analyses.DiscussionExercise training improves functional exercise capacity and may improve health-related quality of life in adults with ILD. AER_RES_BREATH showed the strongest signal for 6MWD, but limited direct comparisons preclude its designation as the optimal intervention. Evidence for FVC% predicted was less robust and should not be interpreted as evidence of disease modification.Systematic Review Registrationhttps://www.crd.york.ac.uk/PROSPERO/view/CRD420261399024, identifier PROSPERO CRD420261399024.
