“…Another study conducted in the group of elite volleyball players also showed improvements in CMJ parameters like: flight time (+5.3%), peak power (+16.2%) and peak concentric force (+6.5%) without any side effects of caffeine ingestion in the amount of 5 mg/kg (42). Protocol used in this research did not show any changes in the CMJ height after caffeine ingestion.…”

BackgroundThe purpose of this investigation was to examine the acute effects of a commercially available multi-ingredient performance supplement (MIPS) in comparison to caffeine, on reactive agility and jump height, in recreationally-trained handball male players. MethodsThe study followed a randomized double-blind, crossover design. Twenty-four individuals were treated with placebo, caffeine or multi-ingredient performance supplement (MIPS). Dosage of caffeine in caffeine supplement and MIPS contain the same amounts of caffeine for each subject (5 mg/kg) . All subjects attended a familiarization session 1 week before testing. Participants underwent reactive agility test (Y-test: 1-1-2 test) on three separate days with 72 h apart between test days. Just after accomplishing of each repetition of reactive agility tests participants were asked to perform countermovement jump (CMJ; 2 repetitions separated by one minute break) to establish the average height of jump, that is directly related to lower body power. To assess the significance of differences between the groups studied, Friedmann ANOVA test was used, the chi-square value (χ2) calculated and the p value of statistical significance estimated. ResultsThe research indicated significant inter-group differences in 1-1-2 agility test (p=0.04). The time was significantly shorter for MIPS supplement group in comparison to placebo (-3.4%; p=0.02) and to caffeine (-2.8%; p=0.004) group. Significant improvements (p<0.01) were observed in jump height for MIPS supplement group in comparison to placebo (+5.2%; p=0.001) and caffeine (+5.1%; p=0.001) groups, but not in caffeine to placebo comparison (p=0.84). ConclusionsThe results of these study may contribute to the assessment of the usefulness of multi-ingredient performance type supplementation in comparison to the ingestion of identical amounts of caffeine only in enhancing reactive agility and jump performance.

“…A double-blind randomized crossover study conducted by Zbinden-Foncea et al (2018) was done to determine the impact 5 mg of caffeine per kilogram body mass had on performance of a countermovement jump (CMJ) by ten elite male volleyball players. Study subjects were selected if they had atleast six years of prior volleyball experience and trained at minimum 4 to 5 days a week or 14 hours in a week total for the past year.…”

“…After examination of the seven randomized controlled trials (Punete et al 2017, Marques et al 2018, Grgic et al 2017, Cheng et al 2016, Zbinden-Foncea et al 2018, Potgieter et al 2017, and Fett et al 2017, this literature review sought to determine if caffeine was able to enhance athletic performance through physiological and neuromuscular effects. The end goal of this paper was to prove caffeine could be used as a performance enhancing agent prior to an athletic event to give athletes an advantage during competition.…”

“…Other limitations could be the relationship between serum potassium and interstitial muscle potassium levels due to caffeine showing no changes to serum potassium levels during in the study. Zbinden-Foncea et al (2018) determined 5mg per kilogram body mass caffeine ingested by volleyball athletes led to increased jump height, velocity of jump and force produced during jump in countermovement-jump (CMJ) performance. The caffeine group had increased maximum velocity, maximum acceleration, maximum power, and maximum force generated during concentric contraction.…”

The Effect of Caffeine on Athletic Performance

Hypothesis:The intake of caffeine can increase physical performance during athletic activity Methods:A search for primary sources was done using PubMed with MeSH terms. The search was limited to randomized controlled trials that were published between 2015 and 2020. After application of inclusion and exclusion criteria, seven articles were selected for this literature review. Results:Of the seven randomized controlled trials selected, six demonstrated caffeine ingestion led to a statistically significant increase in physical performance. One of the randomized controlled trials found no statistically significant relationship between caffeine and run timings. The level set for statistical significance for this literature review was set to p < 0.05.Conclusion: With regards to the results of the selected studies, caffeine was shown to have ergogenic activity and was able to increase physical performance during exercise and sporting competition through multiple mechanisms. Further research should be done with greater sample sizes to determine the effect of rate of metabolism on caffeine activity and to compare caffeine responders and non-responders.

“…It is suggested that its effect in a peak power test could be through tetanic tension [ 3 ], however, high and toxic concentrations of caffeine in humans are necessary to produce the aforementioned neuromuscular process [ 3 , 4 ]. One of the increased power events associated with caffeine consumption is countermovement jump (CMJ) height [ 5 , 6 , 7 , 8 , 9 ], which is a useful and sensitive tool to monitor lower limb neuromuscular status [ 10 ]. However, only analyzing the main outcomes of the CMJ prevents us from understanding the neuromuscular function along the force-time curve and the different phases of the jump [ 11 ].…”

Caffeine Doses of 3 mg/kg Increase Unilateral and Bilateral Vertical Jump Outcomes in Elite Traditional Jiu-Jitsu Athletes

Caffeine increases vertical jump, although its effects on kinetics and kinematics during different phases of bilateral and unilateral jumps remain unclear. The aim of this study was to identify the effects of 3 mg/kg on kinetic, kinematic and temporal variables in the concentric and eccentric phases of bilateral and unilateral countermovement jumps. A total of 16 Spanish national team traditional Jiu-Jitsu athletes took part in two experimental trials (3 mg/kg caffeine or placebo) in a randomized, double-blind crossover study. Sixty minutes after ingestion, bilateral and unilateral jumps were performed on a force platform. Compared to the placebo, caffeine increased bilateral jump height (p = 0.008; Δ% = 4.40), flight time (p = 0.008; Δ% = 2.20), flight time:contraction time (p = 0.029; Δ% = 8.90), concentric impulse (p = 0.018; Δ% = 1.80), peak power (p = 0.049; Δ% = 2.50), RSI-modified (p = 0.011; Δ% = 11.50) and eccentric mean braking force (p = 0.045; Δ% = 4.00). Additionally, caffeine increased unilateral RSI-mod in both legs (Left: p = 0.034; Δ% = 7.65; Right: p = 0.004; Δ% = 11.83), left leg flight time (p = 0.044; Δ% = 1.91), left leg jump height (p = 0.039; Δ% = 3.75) and right leg FT:CT (p = 0.040; Δ% = 9.72). Caffeine in a dose of 3 mg/kg BM in elite Jiu-Jitsu athletes is a recommended ergogenic aid as it increased performance of bilateral and unilateral vertical jumps. These increases were also accompanied by modified jump execution during the different phases of the countermovement prior to take-off.
