In brief
What you will learn
- •Breath-hold risk can develop without reliable warning.
- •A dedicated buddy must know the attempt.
- •Short or familiar attempts are not exceptions.
Familiarity does not control hypoxia
Previous success, comfort in the pool or a personal best cannot predict that the next attempt will recover normally.
Use active task-specific supervision
The observer knows the plan, watches the complete attempt and recovery, and is prepared within trained limits.
- Do not hide breath-holds inside swim sets.
- Do not rely on a distant lifeguard.
- Stop when supervision is interrupted.
