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...

The influence of spinning on a time extension in the static apnea during free diving
Braum, Zdeněk ; Fiala, Miloš (advisor) ; Bažant, Filip (referee)
Title: The influence of spinning on a time extension in the static apnea during free diving Objectives: The objective of this work was to find out whether even a short and intensive training can have an affect on the increase of a vital lung capacity, on a time extension in the static apnea, and on a performance improvement during free diving. Methods: The search of available literature and its recherche. Measurement methods determination: digital stopwatch for the apnea, spirometer for the vital lung capacity, and a Sport-tester and a Borg scale for the spinning program. Data collection. Results: The statistical analysis of the values of a vital lung capacity and a static apnea before and after sports training Keywords: diving, vital lung capacity, spinning, apnea, free diving

Comparison of Special Breathing Exercises versus Specialized Physiotherapeutic Interventions for Static Apnea
Šírová, Anna ; Vondrášek, David (advisor) ; Žáková, Lenka (referee)
Title: Comparison of Special Breathing Exercises versus Specialized Physiotherapeutic Interventions for Static Apnea Objectives: The aim of this diploma thesis is to look deeper into the issue of improving performance in static apnea, one of the competitive disciplines of freediving and compare its training with 1) special breathing exercises for divers (Mana, 2018) and 2) physiotherapeutic intevrentions based on working with the diaphragm and deep stabilization system of the spine (Kolář, 2009). The aim was to find out which group achieved a more effective result and what is the overall diference between the training result of both groups in terms of posture quality and performance in static apnea. Methods: The experiment involved 14 healthy people, men and women, aged 19-23 years old. The experiment consisted of three parts: 1) Initial measurement of static apnea and examination of four tests to determine the quality of one's postural muscles, 2) four-week lasting training according to the division into groups (breathing exercises for divers or training based on physiotherapy intervention), 3) final measurement of static apnea and re-examination of posture tests. The obtained data were recorded and processed. Results: It appeared that due to the small amount of statistically signifiant data and...

Physiological differences and potential risks while scuba diving and freediving
Flodr, Tomáš ; Fiala, Miloš (advisor) ; Hošek, Václav (referee)
Title: Physiological differences and potential risks while scuba diving and freediving Objectives: Goal of this study was to prove, whether freedive performed after finished dive using self-contained underwater breathing apparatus, may potentially increase the risk of decompression sickness and afterall put together appropriate principals and guidance for safe combining of both scuba diving and freediving on the same day. Methods: This study used research of local and foreign sources that covered freediving and diving using self-contained underwater breathing apparatus issues. Casual research was also conducted involving 34 participants, all certified self-contained underwater breathing apparatus divers experienced in combining freediving and scuba diving on the same day. Results: Based on the research has been found that a freedive performed after dive using self-contained underwater breathing apparatus may under certain circumstances increase the risk of decompression sickness. Conservative principals and recommendations for safe combining of scuba diving and freediving on the same day were established. Results of this study will be provided to local and foreign diving communities. Keywords: Scuba diving, decompression sickness, nitogen load, freediving, risks

Prolonged apnea: monitoring brain activity in freedivers
Skopalová, Pavla ; Pánek, David (advisor) ; Nováková, Tereza (referee)
Title: Prolonged apnea: monitoring brain activity in freedivers Objectives: The aim of this study is to monitor the brain electrical activity during the prolonged apnea in freedivers. Prolonged apnea in the water and prolonged dry apnea were compared to each other and also to a resting state before the apnea, all states with the eyes closed. Brain activity was obtained from the scalp EEG and evaluated using the sLORETA program. Methods: The research was conducted in 11 healthy men at the age of 23 - 51. The data was obtained from the scalp EEG. The record was first taken at a resting state before the apneas with eyes closed, then at maximum prolonged dry apnea with eyes closed and finally at maximum prolonged apnea in the water with eyes closed. The lenghts of the prolonged apneas ranged from 2:15 minutes to 5:30 minutes in idividual probands. There were pauses of at least three minutes between each apnea as by the proband's needs. The compared pair groups were following: prolonged apnea in the water against prolonged dry apnea, prolonged apnea in the water against resting state before the apnea and finally prolonged dry apnea against resting state before the apnea, all with the eyes closed. Selected sections of EEG record without artefacts were processed by sLORETA program. In the statistical...

Influence of temperature on the diving reflex
Soustružník, Ondřej ; Vondrášek, David (advisor) ; Bažant, Filip (referee)
Title: Influence of temperature on the diving reflex Background: It is likely that the sum of the defense systems of the organism to changes in temperature known as the diving reflex occurs in each individual differently depending on the physical preparedness. Objectives: Check the effect of temperature on performance-diving reflex two different groups - experienced and novice divers. On the basis of experimental testing in hot and cold water, check the reaction of the body to different environmental conditions. Based on the physiological changes in an organism to assess whether it was demonstrated physiological ability of the body, known as the diving reflex. Methods: Experimental testing beginner diver (n = 5) experienced divers (n = 5) in hot water of temperature 20 - 25 ř C and cold water at a temperature of 4-6 ř C in the static apnea. Based on the measured values, changes in the body, heart rate, oxygen saturation, the overriding influence of sympathetic and parasympathetic, concentration and relaxation index to assess the extent of reaction of the organism and the subsequent involvement of the defense systems of the organism, as called diving reflex. To assess the difference between groups were used statistical methods - Cohen da Kolmogorov-Smirnův test. Results: The results of experiments...
