“…From a methodological standpoint, our study allows us to identify themes that refresh the ideas of some highly cited review articles presenting studies relating coffee/caffeine to sport [ 6 , 23 , 67 , 68 ]. Our study also provides greater coverage of the articles analyzed (larger article dataset size) than other recent review studies [ 17 , 25 , 26 ], also analyzing the relationships between the selected articles [ 35 ]. However, we recognize that this type of limited review study [ 17 , 25 , 26 ] tends to favor the specificity of the articles selected for analysis.…”

“…Sports activity also requires these strategies, with caffeine being frequently consumed in sports and physical activity for its ergogenic properties, such as stimulation of the central nervous system and a greater development of muscular strength [ 18 , 22 , 23 , 24 , 25 , 26 , 27 ].…”

“…Although there are several ways to consume caffeine during exercise, (caffeine anhydrous, sports drinks, caffeinated carbohydrate gels, and chewing gum), a popular method among athletes is coffee, which is also used by sportsmen [ 25 , 26 , 28 ]. There are several studies in different disciplines on the effect of caffeine.…”

Bibliometric Analysis of Studies on Coffee/Caffeine and Sport

This article provides an empirical overview of coffee/caffeine studies in relation to sport worldwide, an incipient but growing relationship that has existed since 1938, although systematized over time since 1999. The extracted articles were examined using a bibliometric approach based on data from 160 records stored in the Web of Science (JCR) between 1938 and August 2021, applying traditional bibliometric laws and using VOSviewer for data and metadata processing. Among the results, these articles highlight an exponential increase in scientific production in the last two decades, with a concentration in only 12 specific journals, the hegemony of the USA among the co-authorship networks of worldwide relevance, and the thematic and temporal segregation of the concepts under study. This article concludes a high fragmentation of the authors with the highest level of scientific production and an evolution of almost 20 years in relevant thematic topics, and a concurrent concentration in three large blocks: (1) coffee consumption and risk factors, (2) health and coffee consumption, and (3) metabolism and sport correlated with the intake of coffee, which are distanced in time, providing evidence of an evolution that gives way to the irruption of alternative visions in the relationship of coffee and caffeine with sport.

“…In a double-blind, Latin-square randomized, crossover, placebocontrolled design, in which participants and treatments were the blocking factors, 46 recreationally active participants (27 men: [mean ± SD] age = 29 ± 6 years, height = 180 ± 6 cm, body mass = 78 ± 12 kg;VO 2 max = 55 AE 11 ml • kg −1 • min −1 and 19 women: age = 28 ± 6 years, height = 166 ± 7 cm, body mass = 72 ± 11 kg;VO 2 max = 41 AE 9 ml • kg −1 • min −1 ) completed a 5-km cycling time trial on a cycle ergometer 60 min following the ingestion of 0.09 g/kg coffee providing 3 mg/kg of caffeine, or a placebo (PLA). A caffeine dose of 3 mg/kg was ingested as this dose has been demonstrated to offer ergogenic effects (Pickering & Grgic, 2019b). Participants were recreational cyclists and had consistently trained on average 2 ± 1 times per week for at least 1 year.…”

Habitual Caffeine Consumption Does Not Affect the Ergogenicity of Coffee Ingestion During a 5 km Cycling Time Trial

There is growing evidence that caffeine and coffee ingestion prior to exercise provide similar ergogenic benefits. However, there has been a long-standing paradigm that habitual caffeine intake may influence the ergogenicity of caffeine supplementation. The aim of the present study was to investigate the effect of habitual caffeine intake on 5-km cycling time-trial performance following the ingestion of caffeinated coffee. Following institutional ethical approval, in a double-blind, randomized, crossover, placebo-controlled design, 46 recreationally active participants (27 men and 19 women) completed a 5-km cycling time trial on a cycle ergometer 60 m in following the ingestion of 0.09 g/kg coffee providing 3 mg/kg of caffeine, or a placebo. Habitual caffeine consumption was assessed using a caffeine consumption questionnaire with low habitual caffeine consumption defined as <3 and ≥6 mg · kg−1 · day−1 defined as high. An analysis of covariance using habitual caffeine intake as a covariant was performed to establish if habitual caffeine consumption had an impact on the ergogenic effect of coffee ingestion. Sixteen participants were classified as high-caffeine users and 30 as low. Ingesting caffeinated coffee improved 5-km cycling time-trial performance by 8 ± 12 s; 95% confidence interval (CI) [5, 13]; p < .001; d = 0.30, with low, 9±14 s; 95% CI [3, 14]; p = .002; d = 0.18, and high, 8 ± 10 s; 95% CI [−1, 17]; p = .008; d = 0.06, users improving by a similar magnitude, 95% CI [−12, 12]; p = .946; d = 0.08. In conclusion, habitual caffeine consumption did not affect the ergogenicity of coffee ingestion prior to a 5-km cycling time trial.

Mental Performance and Sport: Caffeine and Co-consumed Bioactive Ingredients

The plant defence compound caffeine is widely consumed as a performance enhancer in a sporting context, with potential benefits expected in both physiological and psychological terms. However, although caffeine modestly but consistently improves alertness and fatigue, its effects on mental performance are largely restricted to improved attention or concentration. It has no consistent effect within other cognitive domains that are important to sporting performance, including working memory, executive function and long-term memory. Although caffeine’s central nervous system effects are often attributed to blockade of the receptors for the inhibitory neuromodulator adenosine, it also inhibits a number of enzymes involved both in neurotransmission and in cellular homeostasis and signal propagation. Furthermore, it modulates the pharmacokinetics of other endogenous and exogenous bioactive molecules, in part via interactions with shared cytochrome P450 enzymes. Caffeine therefore enjoys interactive relationships with a wide range of bioactive medicinal and dietary compounds, potentially broadening, increasing, decreasing, or modulating the time course of their functional effects, or vice versa. This narrative review explores the mechanisms of action and efficacy of caffeine and the potential for combinations of caffeine and other dietary compounds to exert psychological effects in excess of those expected following caffeine alone. The review focusses on, and indeed restricted its untargeted search to, the most commonly consumed sources of caffeine: products derived from caffeine-synthesising plants that give us tea (Camellia sinensis), coffee (Coffea genus), cocoa (Theabroma cacao) and guaraná (Paullinia cupana), plus multi-component energy drinks and shots. This literature suggests relevant benefits to mental performance that exceed those associated with caffeine for multi-ingredient energy drinks/shots and several low-caffeine extracts, including high-flavanol cocoa and guarana. However, there is a general lack of research conducted in such a way as to disentangle the relative contributions of the component parts of these products.
