“…As adenosine is a subproduct of different metabolic pathways, the effect of caffeine on the CNS successfully enhances physical performance in a myriad of exercise activities, but it may be especially effective to enhance muscle performance. Evidence in resistance-based exercise indicates ergogenic benefits of acute caffeine intake during bench press maximal strength, muscle power output and muscular strength-endurance (15)(16)(17)(18)(19), with recent meta-data confirming a moderate-to-high effect of caffeine on resistance-based exercise (20). In addition, preexercise caffeine intake has the capacity to increase the total amount of work performed during a strength training session due to more power being produced in each repetition (16) or due to more repetitions executed with caffeine during the whole session (21).…”

Previous research has identified acute caffeine intake as an effective ergogenic aid to enhance velocity and power during bench press exercise. However, no previous investigation has analyzed the effects of chronic intake of caffeine on training adaptations induced by bench press strength training. Thus, the aim of this investigation was to determine the effects of pre-exercise caffeine intake on training adaptations induced by a bench press training protocol. Using a double-blind, randomized experimental design, 16 healthy participants underwent a bench press training protocol for 4 weeks (12 sessions). Seven participants ingested a placebo and nine participants ingested 3 mg/kg/BM of caffeine before each training session. Three days before, and 3 days after the completion of the training protocol, participants performed a one-repetition maximum (1RM) bench press and force-velocity test (from 10 to 100% 1RM). From comparable pre-training values, the strength training similarly increased 1RM in the caffeine and placebo groups (+13.5 ± 7.8% vs. +11.3 ± 5.3%, respectively; p = 0.53). In the caffeine group, the strength training induced a higher mean velocity at 40%, (0.81 ± 0.08 vs. 0.90 ± 0.14 m/s), 60% (0.60 ± 0.06 vs. 0.65 ± 0.06 m/s), 70% (0.47 ± 0.05 vs. 0.55 ± 0.06 m/s), 80% (0.37 ± 0.06 vs. 0.45 ± 0.05 m/s), 90% (0.26 ± 0.07 vs. 0.34 ± 0.06 m/s), and 100% 1RM (0.14 ± 0.04 vs. 0.25 ± 0.05 m/s; p < 0.05) while the increases in the placebo group were evident only at 30 (0.95 ± 0.06 vs. 1.03 ± 0.07 m/s), 70% (0.51 ± 0.03 vs. 0.57 ± 0.05 m/s) and 80% 1RM (0.37 ± 0.06 vs. 0.45 ± 0.05 m/s) (p < 0.05). The placebo group only increased peak velocity at 60 and 70% 1RM (p < 0.05) while peak velocity increased at 10%, and from 30 to 100% 1RM in the caffeine group (p < 0.05). The use of 3 mg/kg/BM of caffeine before exercise did not modify improvements in 1RM obtained during a 4 week bench press strength training program but induced more muscle performance adaptations over a wider range of load.

“…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.…”

“…The effects of caffeine use have been associated with an improvement in muscular endurance and contractile performance, and in the synthesis of nitric oxide, which positively impacts blood flow and progression among patients with Parkinson’s disease [ 14 , 15 , 16 , 17 ]. With a continuous and high consumption of caffeine, this negatively affects human functioning due to the increase in blood pressure, increasing nervousness, euphoria, irritability, insomnia, and diuresis.…”

Bibliometric Analysis of Studies on Coffee/Caffeine and Sport

et al. 2021

View full text Add to dashboard Cite

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.

“…Presence of caffeine, irrespective of dosages, in the oral cavity did not affect the 1-RM strength performance in the current study. If caffeine is ingested, it has been generally accepted that caffeine increases 1-RM strength performance in men [34] and women [35]. Furthermore, in a review of recent research [7], it was examined if there is a difference in caffeine's effect on 1-RM strength between the upper and lower body and it was concluded that caffeine is ergogenic in both lower and upper body strength.…”

High Dose of Caffeine Mouth Rinse Increases Resistance Training Performance in Men

et al. 2021

Caffeine mouth rinsing (CMR) has been shown to enhance exercise performance. However, no studies have analyzed the effects of different dosages of CMR on muscular performance. Therefore, the purpose of this study was to examine the effects of different dosages of CMR on strength (bench press 1 repetition maximum (1-RM)) and muscular endurance (60% of 1-RM repetitions to failure) in resistance-trained males. Fourteen resistance-trained males (age: 23 ± 2 years, height: 179 ± 3 cm, body mass: 83 ± 4 kg, BMI: 17 ± 2 kg/m2) completed four conditions in random order. The four conditions consisted of a mouth rinse with 25 mL solutions containing either 1% (250 mg) of CMR (low dose of CMR: LCMR), 2% (500 mg) of CMR (moderate dose of CMR: MCMR), 3% (750 mg) of CMR (high dose of CMR: HCMR) and sweetened water (placebo: PLA) for 5 s prior to a bench press strength and muscular endurance test. Maximal strength, muscular endurance, heart rate (HR) and ratings of perceived exertion (RPE) were recorded for each condition. There were no significant differences in strength (p = 0.30) and HR (p = 0.83) between conditions. HCMR significantly increased muscular endurance performance (p = 0.01) and decreased RPE values (p = 0.01). In conclusion, CMR did not affect bench press 1-RM strength performance, but muscular endurance responses to CMR seems to be dose-dependent.
