“…It is reasonable to assume that an OTC mouthguard has less contact between the teeth and gums compared to a custom-fit mouthguard; this may cause the total volume of the mouthguard to be greater and could lead to a reduction in the airway opening, thus inhibiting airflow. Although no mouthguards were used, this notion is corroborated by Fujii et al 13 . who found that higher minute ventilation (V E ) immediately following a WAnT led to lower [BL] values.…”

Background/ObjectiveMouthguards are the primary mode of protection against maxillofacial injuries in contact sports, but recent research has also linked performance enhancement to this piece of equipment. The purpose of this study was to test the claims of the Under Armour ArmourBite (UAAB) mouthguard to decrease blood lactate concentration ([BL]) and increase power when compared to a generic over-the-counter mouthguard (OTC) and no mouthguard (NOMG) during an anaerobic performance test.MethodsSeventeen recreationally active males (23.4 ± 2.7 years; 179.6 ± 7.4 cm; 83.0 ± 14.0 kg) were tested using the 30 s Wingate anaerobic test (WAnT) during three separate testing sessions.ResultsThere were no differences in [BL] between any of the conditions immediately or 5 min posttest. There were also no differences in peak, relative or average power, or fatigue index during the WAnT. The UAAB mouthguard was therefore unsuccessful in improving anaerobic performance.ConclusionIt is likely that more expensive, custom-fit dental mouthguards may be necessary for individuals to see any benefits to athletic performance.

“…Despite such findings, the usefulness of VH as an ergogenic aid remains questionable with several studies finding no benefit to performance based outcomes 8,9,[16][17][18] . Hilbert et al 18 found no performance benefits to repeated bouts of handgrip exercise following VH in untrained males.…”

“…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. Sakamoto and colleagues 4 investigated the effect of 30 sec of VH during the rest periods between repeat cycling sprints.…”

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.

“…(1,4) An interesting aspect is that the majority of investigations that have used the WAnT as physical performance index have analyzed the energy systems in isolation (6)(7)(8)(9)(10) or combined with the use of ergogenic aid. (11)(12)(13)(14)(15)(16)(17)(18) Undoubtedly, information produced by these studies has contributed a lot to understanding metabolic aspects and fatigue mechanisms related to high intensity exercise. Nevertheless, it is important to point out that in general in the above studies the analyses were performed by means of blood samples or muscular biopsy.…”

Introduction:The Wingate Test (WAnT) has been used to evaluate anaerobic performance in cycle ergometer. Objective: The purpose of the present study was to analyze the EMG response of the superficial quadriceps femoris muscles during the Wingate anaerobic test (WAnT). In addition, we investigated the influence of these muscles in performance and fatigue during the WAnT. Methods: For this purpose eight male cyclists performed a 30-s WAnT. Electromyographic amplitude (RMS) and median power frequency (MPF) data of the vastus lateralis (VL), vastus medialis (VM), and rectus femoris (RF) muscles, performance index (mean power, MP) and rate of fatigue (fatigue index, FI) were recorded during the test; and compared along six time points. The correlation between EMG data and performance parameters were made. Results: No significant differences were found in maximal EMG amplitude for all the muscles. The MPF of the VL and VM muscles decreased throughout the test (12% and 13%, respectively), however, the decline for the RF was twice greater (25%). Correlation among MP and EMG amplitude was observed only for VL (r=0.83; P<0.01). There was significant correlation between the FI and the MPF decrease in the RF muscle only (r=0.78; P<0.05). Conclusion: During the WAnT, MPF decrease of RF muscle was significantly larger when compared to the VL and VM. The VL muscle electrical activity was positively correlated with MP, suggesting that VL is an accurate predictor of the performance in the WAnT. The MPF decrease of the RF muscle was positively correlated to the FI. These results may be explained by differences in the fiber type composition, biomechanics and architecture properties of these muscles.

Effect of voluntary hypocapnic hyperventilation on the metabolic response during Wingate anaerobic test

Abstract: These results suggest that during short-period all-out exercise (e.g., 30-s WAnT), hypocapnia induced by voluntary hyperventilation reduces the aerobic metabolic rate without affecting exercise performance. This implies a compensatory elevation in the anaerobic metabolic rate.
