CFB may attenuate cardiorespiratory demands without changing lactate in swimmers; leaves open effects on training zones and performance.
Does controlled frequency breathing alter blood lactate and metabolic responses in competitive collegiate swimmers during graded swimming?
Controlled frequency breathing during swimming reduces ventilation, VO2, and heart rate without altering blood lactate levels, suggesting coaches should adjust heart rate training zones when using this technique.
West et al. (2005) studied this question.
