Dose-response effect of photobiomodulation therapy on neuromuscular economy during submaximal running.
Worth trying if it fits your goal and context.
ELI5
In plain language
The purpose of this study was to verify the photobiomodulation therapy (PBMT) effects with different doses on neuromuscular economy during submaximal running tests. (randomized trial; recreational runners).
Effects on Running economy are mixed or unclear from the abstract alone. Treat this as a signal, not a guarantee; confirm methods and context in the full paper.
Takeaways
What the abstract suggests
- • Study question: The purpose of this study was to verify the photobiomodulation therapy (PBMT) effects with different doses on neuromuscular economy during submaximal running tests.
- • Effects on Running economy are mixed or unclear from the abstract alone.
- • Population: recreational runners.
- • Protocol cues (title/abstract): 5 min • 9 km.
Protocol
Protocol (as reported)
- • Intervention/exposure: dose, response (vs placebo).
- • Dose/time/duration cues in abstract/title: 5 min • 9 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 (recreational 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: randomized trial (double-blind, placebo-controlled).
- • Population: recreational runners.
- • Comparator: placebo.
- • Outcomes measured: Running economy.
- • Protocol cues mentioned: 5 min • 9 km.
- • Source: PubMed PMID 29101708 (2018) — Lasers in medical science.
Results excerpt
What the abstract reports
“Eighteen male recreational runners participate in a randomized, double-blind, and placebo-controlled trial, which each participant was submitted to the same testing protocol in five conditions: control, placebo, and PBMT with doses of 15, 30, and 60 J per site (14 sites in each…”

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.
