ELI5

In plain language

BACKGROUND: As an adjunct to running training, heavy resistance and plyometric training have recently drawn attention as potential training modalities that improve running economy and running time trial performance. (systematic review / meta-analysis; trained triathletes).

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.

  • Population: trained triathletes.
  • Protocol cues (full paper): 6 months • 4 weeks • 14 weeks • 10 weeks • 60 min • 120 min.

Protocol

Protocol (as reported)

  • Intervention/exposure: resistance training, plyometric.
  • Dose/time/duration cues found in the full paper: 6 months • 4 weeks • 14 weeks • 10 weeks • 60 min • 120 min.
  • 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 triathletes) 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 (randomized).
  • Population: trained triathletes.
  • Outcomes measured: Running economy, Injury risk.
  • Protocol cues mentioned: 14 weeks • 8 weeks • 10 weeks • 6 weeks.
  • Source: PubMed PMID 36370207 (2022) — Sports medicine - open.

Full paper

What the full paper adds

  • Design features (paper): randomized.
  • Participants (paper): trained triathletes.
  • More protocol detail (paper): 6 months • 4 weeks • 14 weeks • 10 weeks • 60 min • 120 min.

Results excerpt

What the abstract reports

In addition, running economy appears to be improved better when training is performed for a longer period in both heavy resistance and plyometric training.

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.
