Uvod: Metodo Wim Hof je ustvaril Nizozemec Wim Hof, ki je znan po izjemni toleranci na mraz in je nosilec mnogih svetovnih rekordov. Njegova metoda temelji na treh stebrih;dihalni tehniki, izpostavljenosti mrazu in meditaciji. V naši raziskavi smo se osredotočili na prvi steber, torej na dihanje. Namen: Namen raziskave je izmeriti srčnožilni odziv človeškega telesa na kratkotrajni stopnjevani telesni napor, če pred naporom izvajamo dihanje po metodi Wim Hof in ga primerjati z odzivom v normalnih razmerah, torej po predhodnem spontanem dihanju. Metode dela: V raziskavi je sodelovalo 14 zdravih mladih preiskovancev. Raziskava je vključevala tri obiske laboratorija, med katerimi je bilo vsaj 48 ur. Ob prvem obisku so se preiskovanci naučili dihanja po metodi Wim Hof. Protokol drugega obiska je bil sledeč: 5 minut mirovanja brez obremenitve, nato 1 minuta ogrevanja na cikloergometru pri 30 W, sledil je stopnjevan napor na cikloergometru, do izčrpanosti, kateremu je sledila faza aktivnega okrevanja s kolesarjenjem pri 30 W za 5 minut, čemur je sledilo še 10 minut pasivnega okrevanja sede na cikloergometru brez obremenitve. Pri tretjem obisku je bil protokol podoben, kot pri drugem, le da se je pred začetkom stopnjevane telesne obremenitve izvedlo Wim Hof dihalno tehniko. Med drugim in tretjim obiskom smo pred naporom, ob maksimalnem naporu in po naporu merili temperaturo kože in kožni krvni pretok na blazinici prsta in na podlakti, prekokožni delni tlak kisika, srednji arterijski krvni tlak in frekvenco srčnega utripa. Rezultati: Pokazali smo, da Wim Hof dihalna tehnika izvedena pred stopnjevano telesno vadbo vpliva na temperaturo kože na blazinici prsta. Ta je bila v primerjavi z meritvami brez Wim Hof dihalne tehnike statistično značilno nižja ob maksimalnem naporu (p = 0,01) in po naporu (p = 0,01). Na ostale merjene srčno-žilne dejavnike Wim Hof dihalna tehnika nima pomembnega vpliva. Razprava in zaključek: Nižja temperatura kože je lahko posledica manjšega pretoka krvi, do česar sklepamo, da pride zaradi aktivacije simpatičnega živčnega sistema z izvedbo Wim Hof dihalne tehnike, ki povzroči vazokonstrikcijo v blazinici prsta. Kožni pretok krvi v blazinici prsta je bil pri meritvi z Wim Hof dihalno tehniko namreč tudi nižji, vendar zaradi velike napake to ni bila statistično značilna razlika v primerjavi z meritvijo brez Wim Hof dihalne tehnike.

Izvleček

Introduction: The Wim Hof method was created by the Dutch Wim Hof, who is known for his exceptional tolerance for the cold and is the title holder of numerous world records. His method is based on three pillars: breathing technique, cold exposure and meditation. In our research, we focused on the first pillar – breathing. Purpose: The purpose of the research was to measure the cardiovascular response of the human body to graded exercise, if before the exercise we perform the Wim Hof breathing method and compare it to the response in normal conditions – after the spontaneous breathing. Methods: 14 healthy young participants took part in the research which comprised of 3 visits to the laboratory, with at least a 48 hour pause between them. On their first visit, the participants learnt how to breathe accordingly to the Wim Hof method. The protocol of the second visit started with 5 minutes of resting / inactivity without any strain, followed by 1 minute of warming up by cycling at 30 W and later a graded exercise until maximum workload was achieved. What followed was a 5-minute active recovery phase with cycling at 30 W, and the end phase was 10 minutes of passive recovery of sitting on a bike without any strain. The third visit was like the second, except that the participants performed the Wim Hof breathing method prior to starting the graded exercise. During the second and third session, we measured the skin temperature and skin blood flow on the fingertip and on the forearm before the strain, during the maximum strain and after the strain. We also measured the cutaneous pO2mean arterial pressure and the heart rate Results: The analysis showed that the Wim Hof breathing method performed before graded exercise affects the skin temperature on the fingertip. This was significantly lower at the point of maximum workload (p = 0,01) and in recovery (p = 0,01) compared to the measurements without the Wim Hof breathing method. Discussion and conclusion: The lower skin temperature of the fingertip may be due to reduced blood flow, which we propose is due to the activation of the sympathetic nervous system by the Wim Hof breathing method, which causes vasoconstriction in the fingertip. Skin blood flow in the fingertip was also lower in the Wim Hof breathing method measurements, but due to the large error, this was not statistically significant, compared to the non-Wim Hof breathing method measurement.
