Study Overview
Brief Summary
Many believe that it is unsafe to swim immediately after having a meal and that it is preferable to wait at least 30 minutes. The fear is that swimming can cause stomach cramps and muscle cramps with discomfort and potentially drowning.
With this randomized controlled trial, the aim was to investigate whether there was any hold in this belief and what could potentially happen by swimming with the stomach full immediately after a meal.
Detailed Description
All volunteers will be adults. Participants will receive both oral and written information about the trial prior to giving consent for participation.
Participants will act as their own control over two days. On the first day, participants will be randomized to either swim immediately after they have eaten their usual lunch or 30 minutes after the last bite. They will do the opposite on the second day. The randomization will be done by throwing a dice.
Prior to swimming, participants will fill out the following:
- Visual analogue scale (VAS) about their well-being
- Questionnaire about their mood state
After swimming, participants will fill out the following:
