Current World Records
Freediving world records represent the extreme edge of human breath-hold capacity. They're useful both as reference for what the sport can achieve, and as context for where recreational training sits relative to those limits.
Static Apnea (STA)
Floating face-down, breath hold for maximum duration.
These times use regulated pre-dive oxygen breathing — standard for competition records. The records represent extraordinary physiological adaptation: heart rates as low as 10 beats per minute, profound spleen contraction releasing oxygen-rich red blood cells, and extreme CO2 tolerance.
Dynamic Apnea with Fins (DYN)
Horizontal underwater swimming on one breath, with fins. Distance is the metric.
Dynamic Apnea Without Fins (DNF)
Same as DYN but using only body undulation.
Constant Weight with Fins (CWT)
Vertical depth diving — the most recognized open water discipline.
Constant Weight Without Fins (CNF)
Depth diving using only dolphin kick with bare feet and hands.
William Trubridge's CNF records are considered among the most remarkable achievements in the sport. Diving past 100m using only bare feet and hands is widely regarded as the pinnacle of freediving technique.
Free Immersion (FIM)
Pulling down and up a line by hand, without fins.
No Limits (NLT) — Historical
Using a weighted sled to descend and an inflatable bag to ascend. No longer in active AIDA competition.
- Men's unofficial record
- 253m — Herbert Nitsch (Austria), 2012. Nitsch suffered a serious decompression accident during this attempt and required extended hyperbaric treatment.
Where Recreational Divers Fit
The world records exist at a different physiological tier from recreational diving. Recreational freediving — exploration, marine life observation, spearfishing — happens at depths that require none of the extreme adaptation that record holders develop.
The Progression of Records
In the 1970s, a 50m constant weight dive was considered near the limit of human capacity. Current records have more than doubled that.
The combination of improved technique (particularly Frenzel and mouthfill equalization), training methodology, and physiological research has driven this progression.
Current records are almost certainly not the final answer on human breath-hold capacity.
