“…RPE also improved with a CHO mouth rinse over plain water. This effect corroborates the findings of Decimoni et al (2018) and Pomportes at al. (2017).…”

“…The findings in this study indicate that a CHO mouth rinse results in significantly higher total training volume when compared to a non-calorie sweetener solution or just plain water. This affirms previous reports by Decimoni et al (2018) and Jeukendrup (2018) who found that CHO mouth rinses work better in high intensity, shortduration exercises. RPE also improved with a CHO mouth rinse over plain water.…”

“…In contrast, this study required subjects to do every set to volitional fatigue or maximum muscular effort. Performing maximal effort produces a more observable difference in perception of effort (Decimoni et al, 2018). A non-calorie sweetener solution showed the same effect on perceived exertion, and thus fatigue, as CHO but without the same ergogenic effect on total training volume.…”

“…Most studies on CHO mouth rinsing are on cycle time trials (Carter et al, 2004;Fraga et al, 2017;Pomportes et al, 2017) while we found only one that measures its direct effect on weight training (Decimoni et al, 2018). A CHO mouth rinse solution produced positive effects on the studies done on cycle time trials and weight training while its effect on the Rating of Perceived Exertion (RPE) remains inconclusive.…”

The effect of carbohydrate (CHO) mouth rinse as an ergogenic aid in aerobic activity is wellestablished. However, its effect on short-duration, high-intensity resistance training is yet to be explored. This study aimed to investigate the effect of a CHO mouth rinse on resistance training performance of trained men in terms of total training volume and perceived exertion in a randomized, cross-over, double-blind design. Fourteen trained men participated in three repeated experimental resistance exercise sessions. Each resistance exercise session consisted of three sets performed until volitional fatigue for the deadlift, squat, bench press, and military press with a load 75% of their tested 1-repetition maximum and 2 minutes rest interval between sets. At the start of each experimental session, and immediately before the third exercise in the sequence, subjects were given a 100 ml solution of either CHO, artificial sweetener (placebo), or water (control) as a mouth rinse for 10 seconds. Comparisons were evaluated with a repeated-measures analysis of variance at α = 0.05. A CHO mouth rinse significantly increased total training volume compared to both the placebo (+23.1%) and control (+25.9%). The effect on perceived exertion was similar for the CHO solution and the non-calorie sweetener solution. The authors conclude that a carbohydrate mouth rinse may benefit resistance training performance in terms of total training volume and perceived exertion in trained men.

“…Clarke et al (2017), reported that, when exercise was performed after an 11-hour overnight fast, the repetitions of the bench press and squat, performed to failure at 60% of one-repetition max, were significantly greater with a 10-second rinse of a 6% carbohydrate solution. Similarly, administration of a 6% maltodextrin mouth rinse elicited a 12% increase in total volume workload during whole-body resistance training session performed after an 8hour overnight fast (Decimoni et al, 2018).…”

The effect of carbohydrate mouth rinse (CHO MR) on resistance exercise performance is equivocal, and may be moderated by carbohydrate availability. This study determined the effect of CHO MR on low-load resistance exercise capacity completed in a fed but glycogen-lowered state. Twelve resistance-trained men (age: 22±4 years; height: 1.79±0.05m; weight: 78.7±7.8kg; bench press 1-RM: 87±21kg; squat 1-RM: 123±19kg) completed two fed-state resistance exercise bouts consisting of 6 sets of bench press and 6 sets of squat to failure at 40% 1-RM. Each bout was preceded by glycogen-depleting cycling the evening before, with feeding controlled to create acute energy deficit and maintain low muscle glycogen. During resistance exercise, participants rinsed with either a 6% CHO MR solution or a taste-matched placebo (PLA) between sets. Total volume workload was greater with CHO MR (9354±2051kg vs. 8525±1911kg, p=0.010). Total number of repetitions of squat were greater with CHO MR (107±26 vs. 92±16, p=0.017); the number of repetitions of bench press were not significantly different (CHO MR: 120±24 vs. PLA: 115±22, p=0.146). This was independent of differences in feeling or arousal. CHO MR may be an effective ergogenic aid for athletes completing resistance exercise when in energy deficit and with low carbohydrate availability. Novelty • CHO MR can increase low-load resistance exercise capacity undertaken in a glycogen-lowered but fed state. • This effect was driven by a greater number of repetitions-to-failure in the squat – using muscles lowered in glycogen content with exhaustive cycling on the evening prior to resistance exercise – but not bench press.

Carbohydrate mouth rinsing has been reported to enhance exercise performance although individual variation exists. The present study aimed to investigate the effect of habitual dietary carbohydrate intake on the efficacy of rinsing a 6% carbohydrate solution on the number of bench press repetitions to failure at 60% of 1‐RM. Twenty‐one recreationally active male participants (Mean ± SD) (age: 24 ± 4 years, height: 177.8 ± 7.8 cm, body mass: 78.6 ± 8.1 kg; bench press 1‐RM: 73.3 ± 20.5 kg) performed bench press repetitions to failure at 60% 1‐RM following rinsing with 25 mL of a 6% carbohydrate (CHO), an artificially sweetened solution (PLA) and a non‐rising control condition (CON) in a randomised cross‐over design. A 7‐day dietary record was completed prior to the first session and subsequently analysed for daily carbohydrate consumption. The number of repetitions performed during CHO (24 ± 4) was higher than CON [21 ± 4; p < 0.001; 95% CI: 1, 4; d = 0.64], as was PLA [23 ± 4; p = 0.002; 95% CI: 1, 3; d = 0.48]. However, there was a large, negative relationship [r = −0.68 (95% CI: −0.86, −0.36), p < 0.001] between daily relative carbohydrate intake (g kg−1) and the difference in the number of repetitions between CHO and PLA. The present study suggests the existence of an inverse relationship between daily carbohydrate ingestion and the efficacy of carbohydrate mouth rinsing; participants who consumed the most daily carbohydrate were generally less likely to see an increase in performance with carbohydrate rinsing.
