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: controlled study.
- • Population relevance: mixed/unclear athlete specificity.
- • Consistency: single-study evidence.
- • Practical recommendation depends on tolerance, context, and whether it protects training consistency.
ELI5
In plain language
This study determined the effect of inspiratory muscle training (IMT), a non-pharmacological treatment on pulmonary function, inspiratory muscle strength and autonomic modulation measured by heart rate variability in obese… (controlled study; n=9 participants).
The abstract doesn’t indicate a clear change in Time to exhaustion under the tested conditions. Treat this as a signal, not a guarantee; confirm methods and context in the full paper.
Takeaways
What the abstract suggests
- • Study question: This study determined the effect of inspiratory muscle training (IMT), a non-pharmacological treatment on pulmonary function, inspiratory muscle strength and autonomic modulation measured by heart rate variability in obese…
- • The abstract doesn’t indicate a clear change in Time to exhaustion under the tested conditions.
- • Population: n=9 participants.
- • Protocol cues (title/abstract): 5 days • 4 weeks.
Protocol
Protocol (as reported)
- • Intervention/exposure: inspiratory muscle training, respiratory (vs control group).
- • Dose/time/duration cues in abstract/title: 5 days • 4 weeks.
- • 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 (n=9 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: controlled study.
- • Population: n=9 participants.
- • Comparator: control group.
- • Outcomes measured: Time to exhaustion.
- • Protocol cues mentioned: 5 days • 4 weeks.
- • Source: PubMed PMID 40833943 (2025) — PloS one.
Results excerpt
What the abstract reports
“Both groups performed 30 breaths twice a day, 5 days/week for 4 weeks.”
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).
- • Single studies often don’t generalize to your event, history, and training load; treat results as a starting point.
- • If your context differs (elite vs recreational; cycling vs running), adjust expectations and be conservative.
- • This is performance information, not medical advice.
