Does Higher Intensity Increase the Rate of Responders to Endurance Training When Total Energy Expenditure Remains Constant? A Randomized Controlled Trial.
Worth trying if it fits your goal and context.
ELI5
In plain language
BACKGROUND: Standardized training prescriptions often result in large variation in training response with a substantial number of individuals that show little or no response at all. (randomized trial; n=31 trained participants).
The abstract suggests a positive effect on VO₂max, Lactate threshold 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: Standardized training prescriptions often result in large variation in training response with a substantial number of individuals that show little or no response at all.
- • The abstract suggests a positive effect on VO₂max, Lactate threshold under the tested conditions.
- • Population: n=31 trained participants.
- • Protocol cues (title/abstract): 10 weeks • 3 day • 16 weeks • 8 weeks • 26 weeks • 50 min.
Protocol
Protocol (as reported)
- • Intervention/exposure: endurance, interval.
- • Dose/time/duration cues in abstract/title: 10 weeks • 3 day • 16 weeks • 8 weeks • 26 weeks • 50 min.
- • Outcomes: VO₂max, Lactate threshold.
- • 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=31 trained participants) working on endurance.
- • Athletes who can measure VO₂max, Lactate threshold 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.
- • Population: n=31 trained participants.
- • Outcomes measured: VO₂max, Lactate threshold.
- • Protocol cues mentioned: 10 weeks • 3 day • 16 weeks • 8 weeks • 26 weeks • 50 min.

Results excerpt
What the abstract reports
“Maintaining moderate endurance training intensities might not be the best choice to optimize training gains.”
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.
