“…Consequently,

E peak increased in HYP, as a compensatory response aiming to maintain oxygen consumption. In accordance, previous studies observed that the magnitude of the ventilatory response appears a critical factor of performance during a Wingate test in hypoxia (Fallon et al, 2015 ). Indeed, the authors showed that ventilation was elevated at the beginning and throughout the exercise when F i O 2 was decreased from 20.9 to 10% (Fallon et al, 2015 ).…”

Objective: The aim of this study was to determine the effects of sprint interval exercises (SIT) conducted under different conditions (hypoxia and blood flow restriction [BFR]) on mechanical, cardiorespiratory, and muscular O2 extraction responses.Methods: For this purpose, 13 healthy moderately trained men completed five bouts of 30 s all-out exercises interspaced by 4 min resting periods with lower limb bilateral BFR at 60% of the femoral artery occlusive pressure (BFR60) during the first 2 min of recovery, with gravity-induced BFR (pedaling in supine position; G-BFR), in a hypoxic chamber (FiO2≈13%; HYP) or without additional stress (NOR). Peak and average power, time to achieve peak power, rating of perceived exertion (RPE), and a fatigue index (FI) were analyzed. Gas exchanges and muscular oxygenation were measured by metabolic cart and NIRS, respectively. Heart rate (HR) and peripheral oxygen saturation (SpO2) were continuously recorded.Results: Regarding mechanical responses, peak and average power decreased after each sprint (p < 0.001) excepting between sprints four and five. Time to reach peak power increased between the three first sprints and sprint number five (p < 0.001). RPE increased throughout the exercises (p < 0.001). Of note, peak and average power, time to achieve peak power and RPE were lower in G-BFR (p < 0.001). Results also showed that SpO2 decreased in the last sprints for all the conditions and was lower for HYP (p < 0.001). In addition, Δ[O2Hb] increased in the last two sprints (p < 0.001). Concerning cardiorespiratory parameters, BFR60 application induced a decrease in gas exchange rates, which increased after its release compared to the other conditions (p < 0.001). Moreover, muscle blood concentration was higher for BFR60 (p < 0.001). Importantly, average and peak oxygen consumption and muscular oxyhemoglobin availability during sprints decreased for HYP (p < 0.001). Finally, the tissue saturation index was lower in G-BFR.Conclusions: Thus, SIT associated with G-BFR displayed lower mechanical, cardiorespiratory responses, and skeletal muscle oxygenation than the other conditions. Exercise with BFR60 promotes higher blood accumulation within working muscles, suggesting that BFR60 may additionally affect cellular stress. In addition, HYP and G-BFR induced local hypoxia with higher levels for G-BFR when considering both exercise bouts and recovery periods.

“…These findings indicate that peak and relative to body mass anaerobic power have not been discriminating variables in futsal players' performance belonging to different categories. Fallon et al (2014) demonstrated that elite female football players obtained a mean value of 533 W in peak anaerobic power.…”

The current investigation aimed to find the difference between right and left lower limb strength of quadriceps and hamstring muscles and describe young futsal players' explosive strength and anaerobic power. The study comprised 12 university male U-20 futsal players (74.5 ± 9.7 kg;173.2 ± 7.2 cm; 18.7 ± 1.2 yrs.). Isometric strength was measured using an isometric dynamometer, lower limb explosive strength was assessed through the Countermovement Jump and anaerobic power was estimated with the Wingate test. Initially, results were displayed through descriptive statistics. Magnitude-based inference with respective Confidence Intervals (CI=90%) and effect size were used to compare inter-lower limb strength. No substantial differences were found between right and left lower limb, to knee extension and flexion. Team's explosive strength and anaerobic power were 36.7 ± 7 cm and 998.3 ± 125.9 W, respectively. These findings suggest that young futsal players' performance may be less affected due to inter-lower limb asymmetries.

“…They performed a Wingate anaerobic test to determine maximal power (Wmax) (15). The Wingate Test has been used as a major test of muscle power whereas isokinetic devices have been used to determine muscle strength (16). The Wingate Test is commonly known as a method for measuring peak anaerobic power (PP) and mean anaerobic power (PM) (17).…”

The aim of this study was to investigate the effects of ginseng and glutamine supplementation on peak and mean anaerobic power output. Handball players (n=40) were volunteered for this study. Weight and height of the players were measured and the age range was between 17-24 years old (20.7±4.3). The Experimental Group (n=20) that n=10 for ginseng supplementation and n=10 for glutamine supplementation was given glutamine treatment of 0.3g/kg/day of glutamine for a period of six weeks and 400 mg ginseng daily. Control Group (n=20) for two supplementations had no treatment. Each participant performed the Wingate Test on a Monark 894e arm ergometer. Peak power and mean power were determined as the highest and average power achieved during any 30s of the test. There was a significant effect (p<0.05) of the supplementations on W max producing a higher value post-test than the pre-test. The ginseng supplement had more significant effects (p<0.05) on the mean and peak power under anaerobic circumstances in compare to the glutamine supplementation. It concluded to suggest other dosages of ginseng and glutamine should be investigated. Further research could assess the influence of ginseng and glutamine intake and intensive physical exercise involving athletes of other sports and using other performance traits, such as athletic skill elements.

Elite Female Athletes' Ventilatory Compensation to Decreased Inspired O₂During the Wingate Test

Abstract: Under hypoxic conditions, the ventilatory response to the Wingate test is perhaps more important than aerobic capacity per se in determining whether or not Wingate performance is decremented.
