“…In agreement with our results, Pettersen et al (2014) and Lee et al (2014) observed that CAF ingestion (5 mg/kg) had no ergogenic effect on strength performance. However, Pallares et al (2013) tested the effect of three different doses of CAF (3, 6, and 9 mg/kg) on four progressive loads (25%, 50%, 75%, and 90% 1MR).…”

The aim of the present study was to investigate the effects of caffeine (CAF) and carbohydrate (CHO) intake on strength performance and its metabolic and inflammatory responses during concurrent training. Seven active males ingested a double-placebo (P), CAF (capsule 5 mg/kg) or CHO (20% maltodextrin solution) supplementation before strength exercise. Participants performed three randomized sessions of 5,000-m high-intensity intermittent aerobic exercise at maximal intensity followed by strength exercise, performing after the P, CHO, and CAF intake. The blood samples were collected before (pre) and immediately after concurrent strength exercise (post). We found a similar number of repetitions and total volume in all supplementation groups. There was a main effect of time on glucose, lactate, and interleukin (IL)-6 (P<0.05). When compared the changes between groups (postvalues minus prevalues), there was lower glucose in CAF group when compared to CHO group (CAF= 5.0±10.4 vs. CHO=27.8±20 vs. P=15.1±14, P=0.031) and higher IL-6 levels (CAF=11.9±9.2 vs. CHO=−2.4±1.7 vs. P=4.3± 11.7, P=0.017). There was significant interaction for glucose and lactate (P<0.001). In conclusion, CAF and CHO intake did not improve strength performance during concurrent strength training in active males. However, CAF affected immunometabolic responses.

“…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.…”

“…Thus, ratings for inconsistency and imprecision were higher which resulted in a downgrading in the quality of evidence. Secondly, although blood glucose and blood lactate concentrations were mentioned in 2 and 3 studies respectively, mean comparisons were only performed in 1 study [43] and hence the evidence for these 2 outcomes were considered as "sparse" and subsequently labelled as "low quality". However, the quality of individual studies reviewed from the perspective of internal validity was high with PEDro quality scores being ≥ 8.…”

Effects of Caffeine Supplementation on Performance in Ball Games

et al. 2017

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.

Introduction:The objective of this study was to analyze the effect of caffeine ingestion in soccer performance, particularly in the countermovement jump test (CMJ). Material and Methods:A total of 17 players from a U-19 amateur Spanish team participated in this pilot study. A double-blind placebo-controlled randomized experimental design was used in 2 different sessions (1.5 hour per session) separated by 1 week. CMJ was collected at the beginning and at the end of sessions; Rating of Perceived Exertion (RPE) was recorded. Players ingested caffeine or placebo at the beginning of session (minute 0 of session), providing a total of 4mg of caffeine or a placebo per kg of body mass. Side effects from caffeine and placebo ingestions were analyzed. The effect sizes (ES) were calculated using values for Cohen's and Quantitative differences were assessed qualitatively (QA). Results:The jump height with caffeine supplementation at the beginning of training was 37.03 (±3.87) cm and at the end was 39.35 (±4.05) cm, obtaining significant improvements (p<0.05; ES:0.56; QA:99/1/0). Significant differences on CMJ at the end of the training session between caffeine and placebo groups were observed (39.35 [±4.05] cm vs. 36.85 [±3.15] cm; p<0.05; ES:0.65; QA:0/1/99). Significant differences on RPE between groups were observed. A nonsignificant tendency to suffer more side effects with caffeine ingestion was obtained. Conclusions:This study shows how the ingestion of 4mg of caffeine per kg of body mass could be an ergogenic aid to improve soccer performance. However, further studies with bigger soccer players sample would be necessary to refute the present results.

Se siguió un diseño a doble ciego, placebo-control, aleatorizado en 2 entrenamientos (1,5 horas/sesión) separados por 1 semana. El CMJ se recogió al inicio y, al final de las sesiones, la tasa de esfuerzo percibido (RPE) fue recogida. Los jugadores tomaron cafeína o placebo al inicio del entrenamiento (minuto 0), proveyendo 4mg/kg de masa corporal de cafeína o placebo. Se analizaron los efectos secundarios provenientes de la cafeína y del placebo. Los tamaños de efecto (ES) se calcularon utilizando valores para Cohen y las diferencias cuantitativas se evaluaron cualitativamente (QA).Resultados: La altura del salto media cuando se ingirió cafeína fue 37,03 (±3,87) cm al inicio y 39,35 (±4,05) cm al final del entrenamiento, obteniendo una mejora significativa (p<0,05; ES:0,56; QA:99/1/0). Se observaron diferencias significativas en el CMJ al final de los entrenamientos entre la ingestión con cafeína y placebo (39,35 [±4,05] cm vs. 36,85 [±3,15] cm; p<0,05; ES:0,65; QA:0/1/99).
