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: athlete/trained context.
  • Consistency: single-study evidence.
  • Practical recommendation depends on tolerance, context, and whether it protects training consistency.

ELI5

In plain language

The aim of this study was to determine whether whole-body endurance training is associated with increased respiratory muscle strength and endurance. (controlled study; runners).

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: The aim of this study was to determine whether whole-body endurance training is associated with increased respiratory muscle strength and endurance.
  • The abstract doesn’t indicate a clear change in Time to exhaustion under the tested conditions.
  • Population: runners.
  • Protocol cues: abstract may omit dose/timing; use the full paper to replicate accurately.

Protocol

Protocol (as reported)

  • Intervention/exposure: respiratory, breathing (vs comparison group).
  • Dose/time/duration: abstract doesn’t include enough detail; use the full paper’s methods section.
  • 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 (runners) 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: runners.
  • Comparator: comparison group.
  • Outcomes measured: Time to exhaustion.

Results excerpt

What the abstract reports

PImax was similar between the two groups of subjects but the maximum threshold pressure achieved was greater in marathon runners (90 +/- 8 vs 78 +/- 10% of PImax, respectively, mean +/- SD, P < 0.05).

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.
