Why underwater hockey isn't the extreme breath-hold sport you think it is
In short: While many imagine players spending minutes submerged in a high-stakes battle, the reality of underwater hockey is far more rapid. Recent data suggests that for most participants, the game functions less like an extreme endurance test and more like a series of quick, tactical bursts of movement.
Underwater hockey (UWH) originated in 1954 in Portsmouth, England, as 'Octopush.' Created by Alan Blake to keep club members active during cold winters, the sport requires players to maneuver a puck across a pool floor using sticks while holding their breath. Because scuba gear is prohibited, the game naturally involves dynamic apnoea—the act of holding one's breath while moving underwater.
Despite its reputation as an 'extreme-apnoea' sport, a 2023 study measured 2,000 submersion times during various matches to test this classification. Data showed that players spent a mere 12.1 seconds underwater while holding the puck, dropping to 9.3 seconds otherwise. These figures fall significantly short of the 45-second breath-hold requirement typically used to define extreme-apnoea sports.
The study also highlighted a significant gap between perception and reality; aquatics directors estimated submersion times to be over 100 percent longer than they actually were (averaging 22.7 seconds). By proving that routine play involves much shorter durations, the research suggests that UWH is more comparable to competitive swimming—a breathing-controlled sport—rather than a high-risk activity prone to hypoxic blackouts.
This distinction matters for safety and classification. While players must be strong swimmers capable of recovering their breath quickly, the data indicates that the 'one to three minutes' of submersion often cited in lay press reports are not representative of standard play. The sport relies on fluid team formations, like the 3-3 or New Zealand’s 'box formation,' where constant substitution ensures players can cycle back to the surface frequently.
