Mixed
Pre-cooling strategies (e.g., cooling vests, ice slurry, cold water immersion) can improve endurance performance in hot environments by reducing cardiovascular strain and heat storage.
For long events in the heat, try pre-cooling. Wear a cooling vest or drink an ice slurry (about 1 liter) before you start. This helps your body handle the heat better. Avoid cooling your legs too much if you need to sprint, as it might slow you down.
GoodQualifiesMEDIUM confidence
Following the development of commercial cooling systems (e.g., cooling vest), athletes can implement cooling strategies to facilitate heat loss or increase heat storage capacity before training or competing in the heat.
Why this rating
Consensus statement citing multiple studies with mixed results for sprint vs endurance.
