Low risk + high feasibility for most athletes.
ELI5
In plain language
Balsalobre-Fernandez, C, Santos-Concejero, J, and Grivas, GV. (systematic review / meta-analysis; trained runners).
In this systematic review / meta-analysis, the abstract is mixed or unclear for Running economy. Treat this as a signal, not a guarantee; confirm methods and context in the full paper.
Takeaways
What the abstract suggests
- • Study question: Balsalobre-Fernandez, C, Santos-Concejero, J, and Grivas, GV.
- • In this systematic review / meta-analysis, the abstract is mixed or unclear for Running economy.
- • Population: trained runners.
- • Protocol cues (title/abstract): 4 weeks • 12 weeks.
Protocol
Protocol (as reported)
- • Intervention/exposure: strength training, plyometric.
- • Dose/time/duration cues in abstract/title: 4 weeks • 12 weeks.
- • Outcomes: Running economy, Injury risk.
- • 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 strength.
- • Athletes who can measure Running economy, Injury risk 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: systematic review / meta-analysis.
- • Population: trained runners.
- • Outcomes measured: Running economy, Injury risk.
- • Protocol cues mentioned: 4 weeks • 12 weeks.
- • Source: PubMed PMID 26694507 (2016) — Journal of strength and conditioning research.
Results excerpt
What the abstract reports
“Four of the 5 included studies used low to moderate training intensities (40-70% one repetition maximum), and all of them used low to moderate training volume (2-4 resistance lower-body exercises plus up to 200 jumps and 5-10 short sprints) 2-3 times per week…”
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).
- • Reviews and consensus statements mix protocols and populations; recommendations may not match your exact constraints.
- • If your context differs (elite vs recreational; cycling vs running), adjust expectations and be conservative.
- • This is performance information, not medical advice.

Running economy research for endurance athletes
Economy is the cost of speed. Small improvements compound over long races.
Injury risk research for endurance athletes
Most injury risk comes from load spikes and insufficient tissue tolerance — manage both.
