Study note • PMID 18390772
Running economy in early and late maturing youth soccer players does not differ.
Useful, but technique/population sensitive.
ELI5
In plain language
The aim of this study was to investigate the influence of maturity on running economy in a population of young soccer players. (controlled study; participants).
The abstract doesn’t indicate a clear change in Running economy 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 investigate the influence of maturity on running economy in a population of young soccer players.
- • The abstract doesn’t indicate a clear change in Running economy under the tested conditions.
- • Population: participants.
- • Protocol cues (title/abstract): 11 km.
Protocol
Protocol (as reported)
- • Intervention/exposure: stride.
- • Dose/time/duration cues in abstract/title: 11 km.
- • 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 (participants) 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: participants.
- • Outcomes measured: Running economy.
- • Protocol cues mentioned: 11 km.
- • Source: PubMed PMID 18390772 (2008) — British journal of sports medicine.
Results excerpt
What the abstract reports
“There was no significant difference in the running economy of early and late maturing soccer players, nor any significant differences in mass adjusted physiological values.”
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.
