Paper Selection Leads to a Misleading Conclusion: Updated Evidence of Ice Slurry Ingestion on Endurance Performance
This short report added to the scientific debate regarding a controversial conclusion published in European Journal of Sport Science. Reasons for the conflicting views have been presented in detail. Importantly, updated evidence suggests that ingestion of ice slurry is an effective countermeasure for endurance performance in the heat. Endurance athletes competing in the upcoming Tokyo 2020 Summer Olympics are encouraged to continue utilizing this simple yet very effective method for best possible performance.
