Study note • PMID 10362391
Effect of endurance training on blood lactate clearance after maximal exercise.
Worth trying if it fits your goal and context.
ELI5
In plain language
The aim of this study was to measure serial changes in the rate of blood lactate clearance (gamma2) in response to sequential periods of training and detraining in four… (controlled study; triathletes).
Effects on Time-trial performance 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 aim of this study was to measure serial changes in the rate of blood lactate clearance (gamma2) in response to sequential periods of training and detraining in four…
- • Effects on Time-trial performance are mixed or unclear from the abstract alone.
- • Population: triathletes.
- • Protocol cues (title/abstract): 5 weeks • 2 weeks • 4 weeks • 30 min.
Protocol
Protocol (as reported)
- • Intervention/exposure: taper.
- • Dose/time/duration cues in abstract/title: 5 weeks • 2 weeks • 4 weeks • 30 min.
- • Outcomes: Time-trial performance.
- • 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 (triathletes) working on tapering.
- • Athletes who can measure Time-trial performance 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: triathletes.
- • Outcomes measured: Time-trial performance.
- • Protocol cues mentioned: 5 weeks • 2 weeks • 4 weeks • 30 min.
- • Source: PubMed PMID 10362391 (1999) — Journal of sports sciences.
Results excerpt
What the abstract reports
“There was a clear upward shift in gamma2 above baseline throughout the first and second training and taper in two subjects; this was less clear in the remaining two subjects, each of whom had a lower deltaCP.”
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.
