Change in breathing economics during exercise due to previous application of breathing exercises based on the Wim Hof method to warm up
MARKO, David
The Wim Hof method is a worldwide phenomenon nowadays. The aim of our work is to determine whether the application of breathing exercises based on WHM will affect the breathing economy in subsequent spiroergometry in adolescent runners (14 boys and 14 girls). Runners underwent two identical graded exercise tests within 3 days, while before one of the tests was performed breathing exercise containing three rounds of controlled hyperventilation and subsequent breath holds. The spiroergometric test consisted of 4 two-minute load phases 1, 2, 3, and 4 W-kg-1. After the application of breathing exercises, there was a significant effect on the kinetics of VO2 (5.09%, 3.11%, 1.55% and 3.39% increase in individual phases of the test). There was also a significant increase of VO2-HR-1 (7.89%, 5.02%, 6.78% and 6.9%). On the other hand, smaller values were measured for the RER, where significance was demonstrated in the first three phases (7.53%, 2.94%, 2.7% and 0.85%). The parameters VE, VT and BF were not significantly affected. No significant differences were measured in the change in the involvement of the breathing sectors. The results of our work show that due to breathing exercises, including controlled hyperventilation and breath holding, the kinetics of oxygen consumption can be accelerated, which can lead to facilitated endurance performance.
