Running Economy: Neuromuscular and Joint-Stiffness Contributions in Trained Runners.
Worth trying if it fits your goal and context.
ELI5
In plain language
To understand the relationship between certain neuromuscular and spatiotemporal biomechanical factors associated with running economy. (controlled study; trained runners).
The abstract reports an association involving Running economy (not necessarily causation). Treat this as a signal, not a guarantee; confirm methods and context in the full paper.
Takeaways
What the abstract suggests
- • Study question: To understand the relationship between certain neuromuscular and spatiotemporal biomechanical factors associated with running economy.
- • The abstract reports an association involving Running economy (not necessarily causation).
- • Population: trained runners.
- • Protocol cues (title/abstract): 3 m.
Protocol
Protocol (as reported)
- • Intervention/exposure: stride, biomechanics.
- • Dose/time/duration cues in abstract/title: 3 m.
- • Outcomes: Running economy.
- • Replication note: abstracts often omit adherence and timing; confirm details before changing training or supplementation.
Fit
Who it helps, and who should skip it
Who it helps
- • Athletes similar to the study population (trained runners) working on biomechanics.
- • Athletes who can measure Running economy with a repeatable workout or time-trial effort.
Who should skip
- • 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: trained runners.
- • Outcomes measured: Running economy.
- • Protocol cues mentioned: 3 m.
- • Source: PubMed PMID 29809077 (2019) — International journal of sports physiology and performance.
Results excerpt
What the abstract reports
“Lower ankle and greater knee stiffness were associated with lower oxygen consumption (r = .527, P = .007 and r = .384, P = .043, respectively).”
Note: excerpts are short; for full context, read the paper.
Limits
Limitations & 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.
