(Universidad Privada Norbert Wiener, 2024-06-05) Muñoz Castillo, José Manuel; Espinoza Rado, Erika Paola
Energy drinks are very popular among young people. Their main ingredients include caffeine and sugar, but previous studies have shown differences between the amount of caffeine and total sugars in the product compared to the amount declared on the label. Methodology: The study population included 10 energy drinks. Two data collection forms were used. Results: Regarding caffeine, it ranged from 28.95 to 78.48 mg/100ml, with 50% exceeding the maximum caffeine limit (>35mg/100ml), and 80% exceeding the declared value on the label. Regarding total sugars, it ranged from 0 to 9.50 g/100ml, with 60% exceeding the maximum sugar range in drinks (≥5g/100ml). Conclusion: Energy drinks contain high amounts of caffeine and total sugars, exceeding the values set by NTP 103.003.2022 and Law No. 30021. Most also do not comply with the declared content on the label, with the Monster Energy Ultra Sugar-Free drink being the most concerning as it contains four times more caffeine than indicated.

Sports caffeine supplementation is suitable to improve physical performance in elite and recreational athletes according to sport classifications (endurance, strength or mixed) to avoid the presence of fatigue. For this secondary research entitled Critical Review: Caffeine supplementation and physical performance in athletes with genetic polymorphism variations", the objective was to identify the effect of caffeine supplementation on physical performance in these types of athletes. Being the clinical question: Will caffeine supplementation (capsules) improve physical performance in elite or recreational athletes with genetic polymorphism variations?, the methodology used was Evidence-Based Nutrition (NuBE) and the databases used for the information search were "PUBMED, MEDLINE, GOOGLE SCHOLAR, EMBASE," reporting 192 clinical investigations from which 12 articles were chosen and evaluated by the critical reading tool CASPE, where finally the randomized clinical trial entitled: Caffeine, CYP1A2 genotype and endurance performance in athletes" was selected; having a level of evidence: AI and Grade of Recommendation: Strong, according to the researcher's experience. It was concluded through critical commentary that caffeine supplementation is recommended to improve physical endurance performance in elite athletes with CYP1A2 genetic polymorphism for homozygotes of the A allele (AA).

Caffeine is one of the most commonly used supplements by athletes due to its various effects, such as delaying fatigue and preserving overall physical and mental performance. This is why the present study, titled "Critical Review: Effect of Caffeine Supplementation on Physical Performance in Basketball," aimed to identify the effect of caffeine supplementation on physical performance in basketball. The clinical question was: What is the effect of caffeine supplementation on physical performance in basketball? The evidence-based nutrition (NuBE) methodology was employed. Information was gathered from EMBASE, SCOPUS, PUBMED, COCHRANE, and SCIENCE DIRECT, with 217 articles found. Ten were selected for critical reading evaluation using the CASPE tool. The systematic review titled "A Systematic Review on the Effects of Caffeine on Basketball Performance Outcomes" was chosen, with a level of evidence AI and a strong recommendation grade. The critical commentary concluded that caffeine has a beneficial effect on physical performance in basketball at a dose of 3 mg/kg body weight.

General acceptability and caffeine quantification of an energy drink with residual coffee pulp.
(Universidad Privada Norbert Wiener, 2020-04-30) Salca Quispe, David Brayan; Inocente Camones, Miguel Angel
Objective: The objective of this research work is to evaluate the amount of caffeine and the level of acceptability of an energy drink made with residual coffee pulp. Materials and methods: The study is cross-sectional, prospective and analytical. Three formulations of different concentrations were prepared: formulation 1 (40% coffee pulp), formulation 2 (60% coffee pulp) and formulation 3 (80% coffee pulp). A hedonic sensory test was applied to determine the characteristics of smell, color, flavor, appearance and acceptability in 100 adults of both sexes from the district of Villa el Salvador. Results: The formulation containing 40% coffee pulp has the highest acceptability in all attributes, while the caffeine content was determined through the AOAC method and was 41.2 mg in 100mL of sample. Conclusions: Through the sensory test, it was concluded that there are differences between the 3 formulations, in which formulation 1 had better acceptability by the panelists.
