“…Since volleyball serving precision and caffeine ingestion has not been evaluated in other studies, we can also compare our results with the findings of Klein et al (22) who investigated the effects of caffeine on tennis stroke accuracy, which is a sport that also requires upper limbs precision and motor coordination. The study results showed that 6 mg·kg -1 of caffeine ingestion improved the number of successful shots during a tennis skill test, accomplished after 45 minutes of intermittent treadmill exercise.…”

“…This allows athletes to consume 6 mg·kg-1 of caffeine, dosage associated with the positive effects on physical and cognitive performance (2,14,16,22) , compared with bigger than 9 mg·kg -1 doses that may cause shivering and shaking, resulting from chronic muscular tension. In addition, high caffeine doses (9 mg·kg -1 or above) may also cause insomnia, anxiety, nervousness, irritability, nausea, and gastrointestinal discomfort (6,34) .…”

Objective: The aim of this study was to identify whether caffeine ingestion affects the precision of volleyball serves. Material and Methods: The study´s design was double-blind, crossover, and counterbalanced. Nineteen college volleyball players took part of the study. They performed two adapted volleyball matches on different days, separated by a 72 hours interval. Before the matches, they consumed randomly 6 mg·kg -1 of caffeine or placebo. After each volleyball match, a serving precision test with two sets of ten serves was performed. Results: The evaluation of each serve's mean (placebo or caffeine) as well as the sum of total points according to the serve's order and intervention were not statistically different. However, the caffeine intervention mean scores were significantly

“…The duration and degree of the standardization protocols differed among studies. The duration whereby participants had to abstain from all dietary sources of alcohol, caffeine and other stimulants ranged from the day itself [36,40] to 24 hours [35][36][37][41][42][43][44][45], 48 hours [34,38,39,[46][47][48][49][50] and the entire study duration (2 sessions separated by 1 week) [51]. Participants were also asked to adopt a similar diet and fluid intake level the day before each experimental trial.…”

“…Only in studies were participants involved in a light and standardized training session the day before each trial [44,49,50]. No information on pre-trial standardization and procedures was reported in 3 studies [34,37,45]. The overall rating for quality of evidence determined using the GRADE approach for both physiological and performance outcomes was low.…”

Effects of Caffeine Supplementation on Performance in Ball Games

Although a large body of evidence exists documenting the ergogenic properties of caffeine, most studies have focused on endurance performance. However, findings from endurance sports cannot be generalized to performance in ball games where, apart from having a high level of endurance, successful athletic performances require a combination of physiological, technical and cognitive capabilities. The purpose of this review was to critically evaluate studies that have examined the effect of a single dose of caffeine in isolation on one or more of the following performance measures: total distance, sprint performance, agility, vertical jump performance and accuracy in ball games. Searches of three major databases resulted in 19 studies (invasion games: 13; net-barrier games: 6) that evaluated the acute effects of caffeine on human participants, provided the caffeine dose administered, and included a ball games specific task or simulated match. Improvements in sprint performance were observed in 8 of 10 studies (80%), and vertical jump in 7 of 8 studies (88%). Equivocal results were reported for distance covered, agility and accuracy. Minor side effects were reported in 4 of 19 studies reviewed. Pre-exercise caffeine ingestion between 3.0 and 6.0 mg/kg of body mass appears to be a safe ergogenic aid for athletes in ball games. However, the efficacy of caffeine varies depending on various factors, including, but not limited to, the nature of the game, physical status and caffeine habituation. More research is warranted to clarify the effects of caffeine on performance measures unique to ball games, such as agility and accuracy. It is essential that athletes, coaches and practitioners evaluate the risk-benefit ratio of caffeine ingestion strategies on an individual case-by-case basis.

“…Caffeine intake can improve high‐intensity performance across a continuum of activities, including swimming (Collomp et al., ), rowing (Bruce et al., ), running (Wiles et al., ; Glaister et al., ), cycling (Wiles et al., ; Santos et al., ), and variable intensity activities (Schneiker et al., ; Klein et al., ). Caffeine is believed to deliver its performance‐enhancing effects through the central nervous system by blocking adenosine receptors (Ribeiro & Sebastião, ) and increasing neural excitability (Walton et al., ).…”

We assessed the efficacy of caffeine mouth rinsing on 3-km cycling performance and determined whether caffeine mouth rinsing affects performance gains influenced by the CYP1A2 polymorphism. Thirty-eight recreational cyclists completed four simulated 3-km time trials (TT). Subjects ingested either 6 mg/kg BW of caffeine or placebo 1 h prior to each TT. Additionally, 25 mL of 1.14% caffeine or placebo solution were mouth rinsed before each TT. The treatments were Placebo, caffeine Ingestion, caffeine Rinse and Ingestion+Rinse. Subjects were genotyped and classified as AA homozygotes or AC heterozygotes for the rs762551 polymorphism of the CYP1A2 gene involved in caffeine metabolism. Magnitude-based inferences were used to evaluate treatment differences in mean power output based on a predetermined meaningful treatment effect of 1.0%. AC heterozygotes (4.1%) and AA homozygotes (3.4%) benefited from Ingestion+Rinse, but only AC performed better with Ingestion (6.0%). Additionally, Rinse and Ingestion+Rinse elicited better performance relative to Placebo among subjects that performed prior to 10:00 h (Early) compared with after 10:00 h (Late). The present study provides additional evidence of genotype and time of day factors that affect the ergogenic value of caffeine intake that may allow for more personalized caffeine intake strategies to maximize performance.
