“…In studies conducted with futsal (De Oliveira et al, 2020) and football (De Oliveira et al, 2019) players, it was found that post-activation potentiation application positively affected repetitive sprint running performance, on the other hand, combination of the application and CHO-MR has been shown to have no additive effect. Similarly, in a study testing performance of 6 × 40 m sprints (round trip = 20 m + 20 m) divided by 20 s of passive recovery, it was found that CHO-MR had no significant effect on repeated sprint performance compared to placebo and control sessions (Bortolotti et al, 2013). Cherif et al (2018) revealed that 5 × 5s × 2sets (3 min rest between sets, 25 s rest between sprints) performed in the fasting state, CHO-MR (10% maltodextrin) performed before each sprint in the maximal sprint protocol does not have a significant influence on sprint performance.…”

“…They have reported that only CHO consumption is more likely to give a beneficial performance effect. Bortolotti et al (2013) and Clarke, Kornilios, and Richardson (2015) stated that the stimulus produced by CHO-MR may not be strong enough to affect short-term and high-intensity training. Although it is known that CHO-MR has the ability to mechanically stimulate the motivation centers (orbitofrontal cortex) in the brain (De Pauw et al, 2015), with the method constructed from the results obtained in this study, it seems that the stimuli used are insufficient to affect the outcome variables of physical performance.…”

Aim: The purpose of this research is to examine the effects of oral rinsing of CHO and NaCl on repeated sprint performance in trained athletes. Methods: Fifteen trained athletes (5 women; 10 men) voluntarily participated in the repeated, single-blind, placebo-controlled and crossover design study. Athletes came to the laboratory with a night fasting four times with an interval of at least 48 hours and participated in the repeated sprint test (10 sec × 6, 40 sec intervals) after 30 minutes of endurance exercise (70% maxVO2). At the 0th, 10th, 20th and 30th minutes of the endurance exercise, it was requested to MR with CHO (6.4% maltodextrin), sodium chloride (6.4%) solution and water (placebo) or no rinsing (control). Results: As a result of the analyzes performed with 3 × 4 ANOVA, the power output variables obtained by repeated sprint performance [peak power, average power, minimum power (W, W/kg) and fatigue index (%)] and fatigue variables (heart rate, blood lactate level and rate of perceived exertion) between sessions were not found to be significantly different. Conclusion From the obtained results, it may be concluded that the method and stimuli used in this study seem insufficient to affect the outcome variables of physical performance.

“…In healthy men on a 3‐day intermittent fasting state, MR with 10 ml of 6.4% CHO solution before each sprint (2×5×5 s, inter‐repetition rest: 25 s, inter‐set rest: 3 min) for 5 s was found not to differ from the control and PLA interventions in the measured repeated sprint variables (Cherif et al, 2018). In young football players, 10‐s CHO‐MR (6% maltodextrin) immediately and 5 min before the 6×40 m sprint test separated by 20‐s active recovery did not show significant effect on best sprint time, mean sprint time, and FI (Bortolotti et al, 2013). Similarly, CHO‐MR had no effect on repeated sprints with direction changes (de Oliveira et al, 2019), single or four VJs, short sprints, or shuttle running (Přibyslavská et al, 2016).…”

“…In the same study, Beaven et al (2013) used a solution containing a combination of 6% CHO‐MR and 1.2% CAF‐MR, which was found to significantly increase PPO during the first sprint and MPO in the fifth sprint compared with CHO‐MR. The reflections of the effects associated with these mechanisms were mostly revealed via tests performed with cyclic efforts such as cycling (Bataineh, Al‐Nawaiseh, Taifour, Khasawneh, & Abualtaieb, 2017; Beaven et al, 2013; Chong et al, 2011; Devenney et al, 2017; Marinho et al, 2019; Phillips et al, 2014) or sprinting (Bortolotti, Pereira, Oliveira, Cyrino, & Altimari, 2013; Cherif et al, 2018; Tomko, Laurent, Fullenkamp, Voth, & Young, 2019; Washif & Beaven, 2018). In the present study, the 30‐s repeated vertical jump (RVJ) test, which was confirmed for reliability and validity (Čular et al, 2018; Pupo et al, 2014), was chosen for detecting effectiveness of CHO‐MR and CAF‐MR.…”

The ergogenic effects of carbohydrate (CHO) and caffeine (CAF) mouth rinse (MR) methods on anaerobic performance remains unclear. Therefore, the aim of this study was to investigate the effects of CHO, CAF, and CHO + CAF combination solutions in mouth on repeated vertical jumping (RVJ) performance in highly trained male athletes. Eight male athletes (mean age: 22 years) underwent test sessions four times with minimum 24-h intervals under fasting conditions. Participants rinsed their mouths with four different 25-ml solutions, namely, CHO (6.4% maltodextrin = 1.6 g), CAF (1.2% caffeine = 300 mg), placebo (PLA, saccharin), or CHO + CAF (6.4%+1.2%) combination, for 10 s and performed a 30-s RVJ test twice with a 5-min interval. Peak power output, vertical jump height, blood lactate level, fatigue index, and rate of perceived exertion of the RVJ tests for different intervention sessions were compared. The statistical significance level was set at p ≤ 0.05. Analyses demonstrated that CHO-(Δ: 3.4), CAF-(Δ: −0.8), and CHO + CAF-MR (Δ: −1.8) interventions led to similar RVJ performance changes compared to PLA. All differences in the dependent variables were statistically insignificant and had moderate and lower effect sizes between interventions (p > 0.05, g < 0.94). Our study did not elicit sufficient evidence to recommend highly trained male athletes the use of CHO-and CAF-MR separately or in combination to enhance jump performance. However, the fact that some differences have medium to large effect sizes suggests that the issue is still worth to be a potential topic for further research. Highlights. Effects of CHO + CAF-MR on anaerobic performance in highly trained athletes have not been investigated using performance tasks requiring high technical skills. . There is not enough evidence to suggest that CHO, CAF and CHO + CAF-MR interventions have beneficial effects on RVJ performance compared to PLA in highly trained male athletes. . Some statistically insignificant differences have medium to large effect sizes. Therefore, the issue is still worth to be a potential topic for further research.

New Insights into Enhancing Maximal Exercise Performance Through the Use of a Bitter Tastant

It is generally acknowledged that for an orally administered ergogenic aid to enhance exercise performance it must first be absorbed by the gastrointestinal tract before exerting its effects. Recently, however, it has been reported that some ergogenic aids can affect exercise performance without prior absorption by the gastrointestinal tract. This is best illustrated by studies that have shown that rinsing the mouth with a carbohydrate (CHO) solution, without swallowing it, significantly improves exercise performance. The ergogenic effects of CHO mouth rinsing in these studies have been attributed to the activation of the brain by afferent taste signals, but the specific mechanisms by which this brain activation translates to enhanced exercise performance have not yet been elucidated. Given the benefits of CHO mouth rinsing for exercise performance, this raises the issue of whether other types of tastants, such as bitter-tasting solutions, may also improve exercise performance. Recently, we performed a series of studies investigating whether the bitter tastant quinine can improve maximal sprint performance in competitive male cyclists, and, if so, to examine some of the possible mechanisms whereby this effect may occur. These studies have shown that mouth rinsing and ingesting a bitter-tasting quinine solution can significantly improve the performance of a maximal cycling sprint. There is also evidence that the ergogenic effect of quinine is mediated, at least in part, by an increase in autonomic nervous system activation and/or corticomotor excitability. The purpose of this article is to discuss the results and implications of these recent studies and to suggest avenues for further research, which may add to the understanding of the way the brain integrates signals from the oral cavity with motor behaviour, as well as uncover novel strategies to improve exercise performance.
