Quick answers
Which local rescue or training agency should I check first?
Use the local lens: coastguard/federation norms and the shop briefing for that bay — not a blog visibility claim.
Why do 25 m and 50 m records differ?
More walls in a 25 m pool mean more push-offs. World Aquatics keeps separate short-course and long-course lists.
When did FINA become World Aquatics?
The federation rebranded in 2022. The 1908 founding date did not change.
Are tech suits allowed?
Textile suits with coverage rules replaced the 2008–2009 polyurethane spike. National bodies publish the current approved list.
Is this the same as triathlon swimming?
No. Triathlon swimming is open-water, usually wetsuit-banded, and ends in a transition. Pool racing is stroke-legal and wall-based.
How do people join?
A club, a time trial, and a meet entry. There is no PADI-style card; there are memberships and qualifying times.
Racing is low-risk compared with wreck or night diving and still produces shoulder injuries and the occasional shallow-water spinal injury. Hypoxic underwater sets have killed trained swimmers.
This is orientation, not sports-medicine advice.
Hazards
- Shoulder overuse — The standard clinic presentation of the sport.
- Shallow racing starts — Some 25 m halls still have unsafe start depths; federations publish minimums.
- Hypoxic underwater repeats — A known fatal pattern. Not a VO2 hack.
- Eating disorders and weight talk — A documented culture risk in aesthetic-adjacent endurance sport.
- Deck slips — Sprinting to a heat in socks.
- Asthma and chloramines — Poor air handling in old halls.
Rules
- Respect start-depth rules — If the meet forbids starts at one end, that is a spinal rule.
- No underwater breath-hold games — Coaches who programme them need a different chapter.
- Report pain early — A week off beats a season of impingement — clinician, not this page.
- Follow warm-up traffic rules — Head-up when merging.
- Safeguarding — Youth sport requires the federation’s chaperone and photo rules.
Red flags
- Sudden shoulder night pain — Stop paddles; see a clinician.
- Chest tightness in a chloramine fog — Exit; tell staff. Not a diagnosis.
- Dizziness after underwater work — End the set. End the fashion.
- A coach who mocks DQs as “cowardice” — Leave the programme.
First response
- Spinal suspicion after a start — Do not “walk it off.” Guards and emergency services.
- Cramp — Stop, wall, stretch — not a medical protocol page.
- Not medical advice — Cardiac and concussion decisions are clinical.
The sport’s danger is mostly cumulative and cultural, not cinematic. Treat underwater contests as a different, dumber sport.
