“…Six studies were excluded because they were performed using animal models or did not evaluate endurance performance. Thus, 13 studies were found to satisfy the inclusion criteria in the first phase [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 25 ]. In the second phase, an additional 532 search results were found, and one study satisfied the inclusion criteria [ 24 ].…”

“…In this study, r amounted to 0.90 and therefore this value was used for all studies in the aerobic endurance analysis. For the analysis of muscular endurance, correlation was calculated using the individual data from two studies [ 20 , 23 ]. In these two studies, correlation values were 0.65 and 0.93.…”

“…The consumption of 10 mg/kg of capsaicin enhanced endurance performance and these effects were largely attributed to the increase in fatty acid utilization [ 11 ]. Deriving from these findings in animal models, recent studies have explored the effects of capsaicin and capsiate on exercise performance in humans [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ]. One of the initial studies investigated the effects of capsaicin on muscular endurance in resistance exercise, using a protocol involving four sets performed to muscular failure with 70% of one-repetition maximum (1RM) in the squat [ 14 ].…”

“…The consumption of 12 mg of capsaicin, 45 min before exercise, increased total volume load performed in the four sets [ 14 ]. Other studies used a very similar protocol of supplementation and exercise tests and did not observe an ergogenic effect of capsaicin [ 23 ]. Capsaicin or capsiate ingestion has also been reported to enhance aerobic endurance in different cycling or running tasks, even though this finding is not consistent in the literature [ 15 , 19 ].…”

“…Such an analysis would be valuable given that some studies might have been underpowered to detect a significant effect. Additionally, this area of research is growing, as evidenced by the publication of seven studies on the effects of capsaicin and capsiate on endurance performance in 2021 and 2022 [ 17 , 18 , 19 , 20 , 23 , 24 , 25 ]. Due to the growing evidence and the conflicting findings, we aimed to perform a systematic review and meta-analysis exploring the effects of capsaicin and capsiate on endurance performance in humans.…”

Several studies have explored the effects of capsaicin and capsiate on endurance performance, with conflicting findings. This systematic review aimed to perform a meta-analysis examining the effects of capsaicin and capsiate vs. placebo on endurance performance in humans. Seven databases were searched to find eligible studies. The effects of capsaicin and capsiate on aerobic endurance (e.g., time-trials or time-to-exhaustion tests), muscular endurance (e.g., repetitions performed to muscular failure), and rating of perceived exertion (RPE) were examined in a random-effects meta-analysis. Fourteen studies (n = 183) were included in the review. Most studies provided capsaicin or capsiate in the dose of 12 mg, 45 min before exercise. In the meta-analysis for aerobic endurance, there was no significant difference between the placebo and capsaicin/capsiate conditions (Cohen’s d: 0.04; 95% confidence interval: −0.16, 0.25; p = 0.69). In subgroup meta-analyses, there were no significant differences between the placebo and capsaicin/capsiate conditions when analyzing only studies that used time-trials (p = 0.20) or time-to-exhaustion tests (p = 0.80). In the meta-analysis for muscular endurance, a significant ergogenic effect of capsaicin/capsiate was found (Cohen’s d: 0.27; 95% confidence interval: 0.10, 0.43; p = 0.002). When analyzing set-specific effects, an ergogenic effect of capsaicin/capsiate was found in set 1, set 2, and set 3 (Cohen’s d: 0.21–29). Capsaicin/capsiate ingestion reduced RPE following muscular endurance (p = 0.03) but not aerobic endurance tests (p = 0.58). In summary, capsaicin/capsiate supplementation acutely enhances muscular endurance, while the effects on aerobic endurance are less clear.

Purpose. This study aimed to verify and compare the potential acute effects of combined and isolated supplementation of caffeine and capsaicin on the performance and the perceived exertion (RPE) in a session of resistance training (RT). Methods. Fourteen trained men participated in the study (5.6 ± 3.5 years of experience in RT and weekly training frequency of 5 ± 0.8 days), aged in average 24.8 ± 3.3 years old, with a mean height of 178.6 ± 4.9 cm, and mean total body mass of 82.4 ± 7.1 kg. We applied a randomized, double-blind, crossover, and placebo-controlled experimental design. The volunteers performed the training protocol after consuming the combined supplementation (CAF+CAP) of capsaicin (12 mg) (CAP) and caffeine (CAF) (5 mg × kg -1 ), in addition consumed them alone. The RT protocol consisted of performing the barbell bench press and incline barbell bench press exercises, with 70% of 1RM until concentric muscle failure. The intervals adopted were 90 and 120 seconds between sets and exercises, respectively. The maximum number of repetitions (MNR), total volume (repetitions × mass lifted), and the RPE in the sessions were registered and compared. Results. One-way ANOVA with repeated measures found no statistically significant difference in the means of MNR (p = 0.176), total volume (p = 0.110), and RPE (p = 0.233) between the experimental conditions. Conclusions. Therefore, combined and isolated caffeine and capsaicin acute supplementation did not improve the upper-body RT performance of trained men. Furthermore, these substances may not attenuate the perception of exertion during RT with maximum repetitions.

Objetivo: O objetivo deste estudo foi investigar os efeitos agudos da suplementação de Capsaicina no desempenho físico de Kickboxers no Specific Kickboxing Circuit Training Protocol (SKCTP), na frequência cardíaca (FC) e na percepção subjetiva do esforço (PSE). Métodos: A amostra foi composta por seis atletas faixas pretas de Kickboxing (idade 30,8 ± 6,47 anos; altura 1,76 ± 0,08 metros; massa corporal 82,43 ± 28,03 kg; experiência na modalidade de 13,71 ± 9,21 anos). O delineamento randomizado, cruzado e duplo cego, foi aplicado em dois encontros separados por uma semana entre eles. Um para a suplementação de Capsaicina 12 mg (CAP) outro para a suplementação Placebo (PLA). Resultados: O teste Wilcoxon verificou que a quantidade total de golpes desferidos foi significativamente maior (p = 0,03; d = 1,55) na condição CAP (369,14 ± 12,10) em comparação à condição PLA (332,28 ± 31,23). O teste Friedman demonstrou que o primeiro round da condição CAP foi superior aos três rounds PLA, e que o segundo round CAP foi superior ao segundo e terceiro round PLA. Não foram verificadas diferenças na frequência cardíaca média entre as condições (CAP: 132,42 ± 19,03 bpm e PLA: 133,57 ± 21,25 bpm; p = 0,87; d = 0,05) e na Percepção Subjetiva do Esforço (CAP: 7,57 ± 1,51 e PLA: 7,00 ± 1,82; p = 0,43; d = 0,34). Conclusão: Conclui-se que a suplementação aguda de Capsaicina melhorou o desempenho dos atletas no SKTCP em comparação ao Placebo, mas não apresentou diferenças para FC e PSE.
