Adaptation of Running Biomechanics to Repeated Barefoot Running: A Randomized Controlled Study.
Worth trying if it fits your goal and context.
ELI5
In plain language
BACKGROUND: Previous studies have shown that changing acutely from shod to barefoot running induces several changes to running biomechanics, such as altered ankle kinematics, reduced ground-reaction forces, and reduced… (randomized trial; n=41 participants).
Results section: no 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: BACKGROUND: Previous studies have shown that changing acutely from shod to barefoot running induces several changes to running biomechanics, such as altered ankle kinematics, reduced ground-reaction forces, and reduced…
- • Results section: no clear change in Running economy under the tested conditions.
- • Population: n=41 participants.
- • Protocol cues (full paper): 8 weeks • 6 months • 1 week • 15 minutes • 5 minutes.
Protocol
Protocol (as reported)
- • Intervention/exposure: cadence, foot strike (vs control group).
- • Dose/time/duration cues found in the full paper: 8 weeks • 6 months • 1 week • 15 minutes • 5 minutes.
- • 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 (n=41 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: randomized trial (randomized, single-blind).
- • Population: n=41 participants.
- • Comparator: control group.
- • Outcomes measured: Running economy.
- • Protocol cues mentioned: 8 weeks • 15 minutes.
- • Source: PubMed PMID 31166116 (2019) — The American journal of sports medicine.

What the full paper adds
- • Design features (paper): randomized, single-blind.
- • Participants (paper): n=41 participants.
- • More protocol detail (paper): 8 weeks • 6 months • 1 week • 15 minutes • 5 minutes.
- • Results section: no clear change in Running economy under the tested conditions.
Results excerpt
What the abstract reports
“After the habituation to barefoot running, the foot strike index was further increased, while the force and average loading rates also increased as compared with the acute barefoot running situation.”

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.
