Why the study?

Does controlled frequency breathing swimming induce systemic hypoxia in elite college swimmers?

Population

9 elite college swimmers experienced with controlled frequency breathing (CFB)

Comparison

Tethered controlled frequency breathing swimming… vs Breathing every two arm strokes (control)

Implication

CFB swimming produces hypercapnia, not hypoxia; hypothesis-generating and should not yet change practice.

Structured PICO

Does controlled frequency breathing swimming induce systemic hypoxia in elite college swimmers?

Population

9 elite college swimmers experienced with controlled frequency breathing (CFB)

Intervention

Tethered controlled frequency breathing (CFB) swimming (breathing every three, four, and five arm strokes) at a constant arm stroke rate of 30/min

Comparator

Breathing every two arm strokes (control)

Outcome

Respiratory and heart rate (fH) responses (including O2 extraction, estimated tidal volume, O2 consumption, CO2 production, respiratory exchange ratio, estimated PAO2, PACO2, and SAO2)surrogate

Controlled frequency breathing during swimming induces hypercapnia rather than the intended systemic hypoxia, as oxygen extraction and tidal volume increase to maintain oxygen consumption.
