Precooling With Crushed Ice: As Effective as Heat Acclimation at Improving Cycling Time-Trial Performance in the Heat.
Worth trying if it fits your goal and context.
ELI5
In plain language
This study compared the effects of precooling (ice ingestion) and heat-acclimation training on cycling time-trial (CTT) performance in the heat. (controlled study; n=7 triathletes).
The abstract doesn’t indicate a clear change in Performance in heat 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: This study compared the effects of precooling (ice ingestion) and heat-acclimation training on cycling time-trial (CTT) performance in the heat.
- • The abstract doesn’t indicate a clear change in Performance in heat under the tested conditions.
- • Population: n=7 triathletes.
- • Protocol cues (title/abstract): 7 g/kg • 30 min • 20 min.
Protocol
Protocol (as reported)
- • Intervention/exposure: heat acclimation.
- • Dose/time/duration cues in abstract/title: 7 g/kg • 30 min • 20 min.
- • Outcomes: Performance in heat.
- • 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=7 triathletes) working on heat.
- • Athletes who can measure Performance in heat 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: n=7 triathletes.
- • Outcomes measured: Performance in heat.
- • Protocol cues mentioned: 7 g/kg • 30 min • 20 min.
- • Source: PubMed PMID 28605253 (2018) — International journal of sports physiology and performance.

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.
