Impact of inspiratory muscle training in patients with COPD: what is the evidence?
How to use this page
This note summarizes one study record. Check the participants, methods, results, and limitations before applying it to training.
- • Design signal: systematic review / meta-analysis.
- • Population relevance: mixed/unclear athlete specificity.
- • Consistency: synthesis evidence present.
- • Practical recommendation depends on tolerance, context, and whether it protects training consistency.
ELI5
In plain language
A meta-analysis including 32 randomised controlled trials on the effects of inspiratory muscle training (IMT) in chronic obstructive pulmonary disease (COPD) patients was performed. (systematic review / meta-analysis; participants).
In this systematic review / meta-analysis, the abstract doesn’t find a clear benefit for Time to exhaustion. Treat this as a signal, not a guarantee; confirm methods and context in the full paper.
Takeaways
What the abstract suggests
- • Study question: A meta-analysis including 32 randomised controlled trials on the effects of inspiratory muscle training (IMT) in chronic obstructive pulmonary disease (COPD) patients was performed.
- • In this systematic review / meta-analysis, the abstract doesn’t find a clear benefit for Time to exhaustion.
- • Population: participants.
- • Protocol cues (title/abstract): 85 m.
Protocol
Protocol (as reported)
- • Intervention/exposure: inspiratory muscle training, respiratory.
- • Dose/time/duration cues in abstract/title: 85 m.
- • Outcomes: Time to exhaustion.
- • Replication note: abstracts often omit adherence and timing; confirm details before changing training or supplementation.
Fit
Who it may help, and who should be cautious
Who it helps
- • Athletes similar to the study population (participants) working on breathing.
- • Athletes who can measure Time to exhaustion with a repeatable workout or time-trial effort.
Who should be cautious
- • If you have symptoms or conditions that make the intervention risky, get professional guidance.
- • If you’re near race day and can’t safely test, defer the experiment.
Methods
What the study actually did
- • Design: systematic review / meta-analysis.
- • Population: participants.
- • Outcomes measured: Time to exhaustion.
- • Protocol cues mentioned: 85 m.
- • Source: PubMed PMID 21282809 (2011) — The European respiratory journal.
Results excerpt
What the abstract reports
“Respiratory muscle endurance training revealed no significant effect on P(I,max), functional exercise capacity and dyspnoea.”
Note: excerpts are short; for full context, read the paper.
Limits
Limitations and bias
- • Abstract-only summaries can miss critical details (population, protocol, adherence, and context).
- • Reviews and consensus statements mix protocols and populations; recommendations may not match your exact constraints.
- • If your context differs (elite vs recreational; cycling vs running), adjust expectations and be conservative.
- • This is performance information, not medical advice.
