Influence of Wim Hof method on freediver performance
Pilušová, Viktorie ; Heller, Jan (advisor) ; Pavlů, Dagmar (referee)
Title: Influence of Wim Hof method on freediver performance Objectives: The aim of this thesis is to find out whether Wim Hof's method (WHM) can demonstrably improve the performance of a freediver and whether, as an added component of regeneration in his training unit, it can demonstrably contribute to the improvement of selected physiological parameters, compared to a group practicing Pranayama in combination with cold exposure and meditation and a control group without intervention. Another goal is to compare the results obtained in the individual groups for a period of two and four weeks of measurement and thus objectify the effect of the selected intervention. Methods: As part of the issue of improving the athlete's performance, selected physiological parameters of individuals engaged in freediving on the breath were observed. For the implementation, the WHM was used, which uses the connection of psychological and physical resistance to stress factors. A total of 32 healthy male subjects in the age range of 32-61 years participated in the study, who were randomly divided by lot into 3 as closely as possible groups of 10-11 members each for WHM or Pranayama training, or into a control group. The experiment consisted of an initial measurement, where input data was taken from the participants and...

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.
