“…In agreement, another study on WHBM reported that a representative subject ended the last BH with a pH of 7.50, a value 0.10 higher than at the start (Kox et al, 2014 ). In comparison, other studies reported improved performance using HV with comparable or smaller pH changes (Sakamoto et al, 2014 ; Jacob et al, 2015 ), greater pH changes (Ziegler, 2002 ), and smaller pH changes using bicarbonate supplementation (Costill et al, 1984 ; Bishop et al, 2004 ). However, other studies did not find improved performance even though comparable or smaller pH changes were reported (Jacob et al, 2008 ; Kairouz et al, 2013 ; Sakamoto et al, 2018 ).…”

“…While the WHM seems to present interesting benefits, there is virtually no published research on its effects on sport performance. However, studies have shown that HV, which is part of the WHBM, can improve anaerobic performance (Ziegler, 2002 ; Sakamoto et al, 2014 ; Jacob et al, 2015 ). HV induces hypocapnia and drives the reaction sequence

more to the right, elevating blood pH (Saladin and Miller, 2004 ).…”

The Wim Hof breathing method (WHBM) combines periods of hyperventilation (HV) followed by voluntary breath-holds (BH) at low lung volume. It has been increasingly adopted by coaches and their athletes to improve performance, but there was no published research on its effects. We determined the feasibility of implementing a single WHBM session before repeated sprinting performance and evaluated any acute ergogenic effects. Fifteen amateur runners performed a single WHBM session prior to a Repeated Ability Sprint Test (RAST) in comparison to voluntary HV or spontaneous breathing (SB) (control) in a randomized cross-over design. Gas exchange, heart rate, and finger pulse oxygen saturation (SpO2) were monitored. Despite large physiological effects in the SpO2 and expired carbon dioxide (VCO2) levels of both HV and WHBM, no significant positive or negative condition effects were found on RAST peak power, average power, or fatigue index. Finger SpO2 dropped to 60 ± 12% at the end of the BHs. Upon the last HV in the WHBM and HV conditions, end-tidal CO2 partial pressure (PETCO2) values were 19 ± 3 and 17 ± 3 mmHg, indicative of respiratory alkalosis with estimated arterial pH increases of +0.171 and of +0.181, respectively. Upon completion of RAST, 8 min cumulated expired carbon dioxide volumes in the WHBM and HV were greater than in SB, suggesting lingering carbon dioxide stores depletion. These findings indicate that despite large physiological effects, a single WHBM session does not improve anaerobic performance in repeated sprinting exercise.

“…Hyperventilation attenuates the post-exercise decrease in pH, reduces CO 2 saturation, and increases anaerobic power, especially at the end of a set of efforts [ 55 ]. A beneficial effect of pre-exercise hyperventilation before a competition on short-distance swimming performance has also been reported [ 56 ]. The reduction in CO 2 saturation and hydrogen ion concentration due to hyperventilation improves physical performance during repeated resistance efforts [ 55 ].…”

Background: Acid–base balance (ABB) is a major component of homeostasis, which is determined by the efficient functioning of many organs, including the lungs, kidneys, and liver, and the proper water and electrolyte exchange between these components. The efforts made during competitions by combat sports athletes such as kickboxers require a very good anaerobic capacity, which, as research has shown, can be improved by administering sodium bicarbonate. Combat sports are also characterized by an open task structure, which means that cognitive and executive functions must be maintained at an appropriate level during a fight. The aim of our study was to analyze the changes in ABB in capillary blood, measuring levels of H+, pCO2, pO2, HCO3−, BE and total molar CO2 concentration (TCO2), which were recorded 3 and 20 min after a three-round kickboxing bout, and the level of technical and tactical skills presented during the fight. Methods: The study involved 14 kickboxers with the highest skill level (champion level). Statistical comparison of mentioned variables recorded prior to and after a bout was done with the use of Friedman’s ANOVA. Results: 3 min after a bout, H+ and pO2 were higher by 41% and 11.9%, respectively, while pCO2, HCO3−, BE and TO2 were lower by 14.5%, 39.4%, 45.4% and 34.4%, respectively. Furthermore, 20 min after the bout all variables tended to normalization and they did not differ significantly compared to the baseline values. Scores in activeness of the attack significantly correlated (r = 0.64) with pre–post changes in TCO2. Conclusions: The disturbances in ABB and changes in blood oxygen and carbon dioxide saturation observed immediately after a bout indicate that anaerobic metabolism plays a large part in kickboxing fights. Anaerobic training should be included in strength and conditioning programs for kickboxers to prepare the athletes for the physiological requirements of sports combat.

“…A small but growing body of research has focused on the potential ergogenic effects of various breathwork practices including voluntary hyperventilation (VH); an intentional and sustained increase in breathing frequency and/or depth leading to respiratory alkalosis and a reduction in hydrogen ions [1][2][3][4][5][6][7] . During exercise hydrogen ions build up and impair excitationcontraction-coupling resulting in reduced energy supply and fatigue 7 .…”

“…The reduction in hydrogen ions from VH may therefore delay muscle fatigue and subsequently improve performance in activities relying on sustained muscular contractions 4,6,7 . Jacob et al 3 determined that VH performed prior to a 50m swim resulted in significantly faster times. Additionally, Fujii et al 8 and Dobashi et al 9 found that 5 or 20min of VH prior to Wingate sprints resulted in similar peak and mean power outputs but lower O2 uptake.…”

Introduction: To examine the effects of voluntary hyperventilation (VH) between sets of bench press (BP) and squat (SQ) at 70 and 90% 1RM on repetitions to failure, power, bar velocity, blood lactate, session RPE (sRPE), and muscle oxygen saturation (SmO2). Methods: Fifteen recreationally trained (2.92 ± 2.18 yrs. of resistance training experience) college-aged males (20.27 ± 1.39 yrs., 182.40 ± 7.42 cm, 82.23 ± 10.84 kg) performed 3 sets of BP and SQ to failure at 70 and 90% 1RM on separate days with normal breathing (CON) or 30 sec of VH during inter-set rest periods. Results: There were no significant differences between conditions for repetitions, power, velocity and sRPE (p’s > 0.05) at either intensity. VH resulted in a slight attenuation of blood lactate accumulation between sets 2 and 3 of SQ (p = 0.037). There was a significant condition and intensity interaction for SmO2 of the pectoralis (p = 0.034) with VH producing higher SmO2 at 90% 1RM and lower SmO2 at 70% 1RM than the CON. Conclusions: Voluntary hyperventilation did not produce an ergogenic effect in recreationally trained individuals which, when considering current evidence, suggests other factors including training experience, may influence the effectiveness of VH.
