Abstract

Assessment of the Effects of Controlled Frequency Breathing on Lactate Levels in Swimming

A randomly assigned maximal effort 100-yd swim test was conducted twice, once with normal breathing (NB) pattern (1 breath every 2-3 strokes), and the second using controlled frequency breathing (CFB) pattern (1 breath every 7 strokes) in 21 trained female swimmers (19.0 ± 1.1 years). Post-swim blood lactate levels, heart rate, and time to completion were measured and assessed after completion of each bout. Blood samples were taken from the earlobe at rest (prior to the bout), 0-min,1.5-min, 3-min, and 5-min post-swim. Heart rate was taken at rest and at the same time points as blood lactate.
